[center][u]Eric and Milo: Working Out
[/u]By Green[/center]


It was a quiet Saturday in the Thompson home. The man of the house, Alexander, and his lovely wife Karen were at a neighbour's barbecue, spending time with their friends, since they'd been busy lately. The only noise of note inside was a rather spirited conversation between their youngest son, Milo, and their only daughter, Anne, who was the middle child. Anne was following Milo as he descended the stairs from his room, and, as any sister worth her salt is known to do, was being rather a pest.
        "No. Leave me alone."
        "Come on, Milo, at least let's talk about it, come to a compromise!"
        "I said no, Annie!" 
        "I don't think you understand exactly how much this would mean to me, little brother. Maybe I should ask Eric, and he can use his 'magic touch' to convince you..."
The younger German shepherd turned around and glared at his sister even as he blushed. 
        "Dammit, Annie, I am [i]not [/i]going to act out your gross yaoi fantasies for you! I'm not Eric's ook, I'm not going to call him 'onii-chan', and I'm not going to yell - whatever that was before I come!"
Smiling brightly, as if he were happily agreeing with her, Anne winked at her brother.
        "Uke, Milo. It's pronounced oo-kay. And I wanted you to say 'dame' when you come. [i]Dah-may. [/i]It means -"
He threw his hands up in the air, exasperated. 
        "I don't [i]care[/i] what it means!"
        "- It means 'It's no use!', like you're trying real hard not to come, but you can't help it because it feels so good... Sound familiar?"
The other canine stopped in his tracks and looked at her, shocked [i]and [/i]embarrassed. She giggled and winked again.
        "Say what you will about my 'gross yaoi fantasies', little brother, but face it; you're [i]living[/i] one!" 

Milo clearly didn't know how to respond to that one, apart from blushing and frowning at his sister. Anne put her hands on her hips and clicked her tongue at him, her stern appearance totally betrayed by her gleefully wagging tail.
        "Don't give me that look, Milo. You guys never invite me to watch, so I've gotta make every session I [i]do [/i]get to see count."
Reaching up, she carefully lowered her glasses, looking at him over the rims, for maximum dramatic effect.
        "Why [i]do [/i]you guys do that, anyway? Where's the fun in blackmailing you guys if I never get to enjoy it?"
        "For starters, if you're going to keep calling it blackmail, then I guess we don't see much reason to do you any favours."
Anne crossed her arms and said nothing, just staring at the younger shepherd. Put on the spot, Milo looked away, avoiding eye contact, his tail firmly between his legs. 
        "Well, [i]jeez[/i], Annie, it just feels really weird to go 'oh, we're about to do it, let's go invite our sister'."
The female laughed once, shaking her head.
        "And it doesn't feel weird to go 'I'm feeling horny, I should go [i]have sex with my brother[/i]'?"
Walking towards the living room to get away from the stairs, Milo looked over his shoulder at his sibling, feeling himself losing the argument.
        "As opposed to, 'I'm feeling horny; I'll ask my brothers to have sex'?"
        "Hey, at least I [i]acknowledge [/i]that I'm a pervert."
Not really having a response to that either, Milo stopped, desperately grasping for words. Before he could think of anything, Anne walked around behind him and he felt his sister's hands on his shoulders, gently massaging his muscles, kneading the stress away. 
        "Come on, Milo, it's not [i]that[/i] bad when I'm around, is it? It's getting to the point where I'm considering getting you both webcams so I don't miss anything."
        "B-but you always try to tell us what to do, and what positions to use, and stuff..." 
        "Okay, so I'm a bit of a backseat - uh, let's not put a verb there, actually. But still, think about it, little guy, I could help cover for you if you get that prostate thing going on while you're with Eric. By the way, when [i]are[/i] you two gonna start doing it again? I thought you were all collected and okay and stuff since I helped you figure out your 'problem', but Eric says you've been avoiding him. I still don't know why you don't just [i]tell [/i]him about it..."

Milo had been horrified to discover, shortly after he and his brother had crossed that line for the first time, that he [i]really [/i]enjoyed being on the receiving end of anal sex, and had on a few occasions reached orgasm hands-free from that stimulation alone. The previous week, his sister had helped him figure out that it didn't indicate, as he feared, that he was secretly as gay as the day is long and madly in love with his brother, he just had a very sensitive prostate. However, Milo and Eric had not yet resumed their secret trysts, and just the [i]idea [/i]of explaining his prostate issue to his older brother made Milo anxious.
        "P-please, Annie, I'm just not ready yet..."
Milo whimpered. Anne was [i]surprisingly [/i]good at this shoulder blade massage, and with her cooing, reassuring tone, he was mildly worried that she was going to be able to talk him into whatever she wanted. He briefly envisioned himself wearing a frilly pink dress while Eric railed him, when, as if summoned by the thought, their older brother appeared, walking up from his basement bedroom with a duffle bag slung over his shoulder, whistling idly to himself. The eldest shepherd went round the corner and paused for a moment, taking in the sight before him, and Milo looked at him pleadingly, mouthing the words [i]help me[/i]. Eric smirked and just stood there for a moment, clearly trying to decide whether to have mercy on his brother or make it worse, in true Older Sibling fashion, before he cleared his throat.
        "Hey Milo, where's your stuff? I told you to get ready like an hour ago."
Anne leaned around Milo, not having noticed their brother standing there.
        "Oh, hey Eric. Are you guys going somewhere?"
The smile on her muzzle made it rather obvious what she hoped they were planning. 
        "Yeah, I'm going to the gym and Milo wanted to join me this time, put a bit of muscle on those arms. Right, Milo?"
Desperate for any out, Milo gratefully nodded.
        "Y-yeah, sorry, Annie distracted me; I'll just grab some stuff."
He hurried upstairs to get a change of clothes appropriate for working out, as well as an all-important stick of deodorant. He glanced over his shoulder once before he reached the top of the stairs, and regretted it; Anne's smile hadn't diminished one iota. In fact, the announcement that they were going to the gym, a somewhat cliché location for homosexual encounters, had her positively [i]beaming[/i]. As Milo disappeared into his room, Eric walked up to the front door, setting down his gym bag to sit on the stairs and put his shoes on, while Anne walked up and leaned up against the wall next to him, still grinning. 
        "Nice of you to cover for him like that."
Eric didn't bat an eye, continuing to tie his shoes.
        "I'm not sure what you're talking about."
Anne crossed her arms, chuckling.
        "Oh come on, big brother, you expect me to believe Milo suddenly has an interest in exercising?"
As a general rule, Eric Thompson was [i]much [/i]better at lying than his brother, who crumbled under the slightest scrutiny from an authority figure. Anne was notoriously good at reading her family, though, so he kept it simple.
        "Sure, he got all embarrassed when I asked, so I assume he's trying to impress Gela."
The distaff sibling's expression darkened just a bit, because that [i]was [/i]actually plausible; in addition to his issues with the secret dalliances with his brother, Milo had a much more normal 'thing' going on with his childhood friend Angela, with both of them insisting that it was purely casual, and no one in either circle of friends and family believing them for an instant. Gela was a tomboy, rather aggressive for a mouse, and Milo sometimes worried that his quiet, somewhat submissive nature wasn't enough for her. Shaking her head, Anne got off the wall and walked away, towards the kitchen.
        "Fine, I'll just have to use my imagination. Have fun pumping iron."
It would have sounded a lot more innocent if she hadn't added a pelvic thrust to the last two words. It was now Eric's turn to frown; Anne had teased him about going to the gym in the past, implying none-too-subtly that he went looking for hot, sweaty manlove rather than for exercise. As if he would be stupid enough to try that in public, especially with Milo acting all weird lately. Practically on-cue, Milo came down the stairs, looking decidedly relieved that their sister was gone.
        "Alright man, thanks a bunch. Now, let's make like a tree and get the fuck out of here..."
He looked around, almost nervously.
        "...Before she gets any more ideas."

About ten minutes later, Eric neatly eased the car to a halt at the intersection, muttering aloud, wondering how he always, [i]always [/i]managed to catch this red light. He glanced over at his passenger, who was staring out the window, lost in thought. Neither of them had spoken since they'd left.
        "...Hey, Milo, I know you're not into working out, I can just drop you off somewhere if you'd like, tell Anne I did it after the session."
The younger shepherd's thoughts turned rather immediately to a certain morphic mouse, but he didn't like dropping in unannounced. 
        "N-no, it's fine, I could probably use it, all the time I spend on the Internet..."
        "Okay."
Another few seconds passed, and Milo thought about turning the radio on to cut the blasted tension in the air. But before he could act on that, his brother apparently decided to confront the issue that had been silently screaming in their heads for the last couple days. 
        "...Look, I... I couldn't help but notice you've been uncomfortable around me since the last time we... you know." 
That wasn't a question, and Milo didn't say anything, suddenly very interested in the plastic floor mat under his feet.
        "Was it something I did, Milo? Something I said? You can tell me, I won't be mad."
Milo swallowed a whimper, still unable to look at his brother. Outside, the light changed, and the car began to roll again, but Eric was still expecting a response. 
        "W-Well, I... uhhh... I..."
Well, that went just great. He shook his head and tried again.
        "See, there's this... [i]thing[/i]... and Annie..."
Now he was trying to skip the really embarrassing part, and in doing so, all of the context for the explanation. He caught himself on the verge of letting out a high-pitched whine, blushing and silently cursing his canine instincts. Eric meanwhile, tried to be helpful, fill in the blanks, even if the look in his eye suggested his idea was his personal worst-case scenario.
        "Look, dude, if you want to stop what we've been doing, go back to the way things were..."
Milo's 'No!' came a little too quickly and with a little too much emphasis for his liking, blushing the instant he did it, then shrugging and looking back out the window. 
        "Look, Eric, it's nothing you did, it's... personal. I don't really wanna talk about it... not yet, anyway. But Annie helped me a lot, and I'm feeling much better now, wouldn't mind, you know... starting up again. I just didn't know how to, uh, ask you." 
Letting out a sigh that Milo could [i]swear [/i]was one of deep relief, Eric glanced over at his brother with a grin. 
        "Great. Glad to clear things up."
Milo finally looked over and smiled back, if a bit less enthusiastically than his brother. Eric brought his eyes back to the road, and added on to that thought.
        "We're almost there. Don't worry, it won't be so bad, you don't have to work any harder than you want to. Hey, maybe you'll even enjoy it. Be fun to have some company at the gym every once in a while, eh?"
Milo nodded absently, feeling a little like a liar for leaving out the explanation. 
        "Maybe... I've never really done the whole gym thing, aside from that year I took weight training instead of phys. ed. But I was never really into it, I don't really remember any of the exercises."
        "Well, this place has got some better stuff than the school can afford, let me tell you. Not to mention girls in spandex outfits and short shorts."
Both brothers couldn't help but grin at that. Whether or not their feelings for each other went beyond mere stress relief, as their sister [i]loved [/i]to suggest, there was no question whether they still appreciated the female form. From the way they were both more relaxed, easier with a grin and a comment, it seemed that both brothers felt significantly better than they had when they left the house, and the rest of the brief trip was much easier on them both.

Soon enough, they'd arrived at the gym, and gone through the procedures of signing in, and having Milo listen to a short spiel about the benefits of full membership while he signed a form to get a guest pass. Milo looked around, impressed, and a little intimidated, by the vast array of equipment around them, but Eric said he'd explain where everything was after they changed. Upon walking into the locker room, Milo was relieved to discover that the area didn't smell like sweaty balls, as he had feared. It [i]was[/i], however, occupied by a number of men of a wide selection of species, in a variety of stages of buffness, all naked or in the process of getting changed in one direction or the other. As he stood nervously by the entrance, one of the shower stalls in the back opened up, and an [i]enormous [/i]rhinoceros ambled out, running a towel along his back, fully at ease with his nudity. Realizing with a start that he was staring at the man's impressive package (out of awe, not 'interest'), Milo blushed and forced his eyes away, moving quickly to the side wall, where he opened the locker next to Eric's and began to get changed quickly, keeping his eyes glued to either his bag or the inside of his locker, never straying. 
        "Good idea, little brother, keep those eyes front and center. Best not to let your view [i]linger[/i]."
Stripping his shirt off, revealing one of the slenderest chests in the room, Milo was about to make a wise-ass remark in response when something bumped into his foot. Looking down, he saw a water bottle with a faded Vancouver Canucks logo on the side, having apparently rolled across the floor under the bench. Sensing someone approaching, and being naturally helpful, he knelt down to get it. 
        "Hey, thanks mate."
The voice had a light Australian tinge to it, but the guy's background was the last thing on his mind as he held up the bottle and looked to see who was claiming it - because the border collie standing on the other side of the bench was as naked as the proverbial jaybird, his junk at the same level as Milo's face. It was plain to see that the guy had Inherited bits, which is to say that unlike Milo's 'human-but-fuzzy' parts, this gentleman's penis was currently hidden inside his body in a sheath very much like that of a feral canine, and presumably possessed the same tapered shape and swelling knot as well. The German shepherd had never been this close to Inherited genitals before, and because he tried with all his might [i]not [/i]to think about anything untoward, his mind immediately conjured up the image of himself leaning forward and licking the stranger until he could get a better look at his exotic shaft. Blushing and silently cursing himself, he banished all thought of fellatio from his mind and held up the water bottle, which the collie took, grinning thankfully as he performed a little salute with it, nodding to the younger canine as he held it up as if proposing a toast.
        "Cheers."
With that, he turned around and walked back over to an open locker, and Milo looked down at his bag and swallowed a groan of deepest embarrassment. It didn't help when he felt his brother's elbow nudging his shoulder. 
        "Hey - hey Milo. I think he was checking you out. You should ask for his number!" 
If looks could kill, the glare he sent towards the older shepherd not only would have ended his existence, it would have kept right on going and melted a hole in the ceiling behind him.

A few minutes later, the Thompsons stepped out of the change-room, taking in the impressive array of gleaming machines designed to get people in shape. Milo stepped a little ahead of Eric, looking a bit overwhelmed, but Eric was distracted for a moment. 
        "Hey Milo, you think those shorts are tight enough?"
The other canine looked over his shoulder, frowning.
        "Shut up. I was in a hurry, okay? Grabbed the wrong ones, haven't worn these in a few years."
The plain blue shorts were indeed rather tight, clearly outlining the dog's firm buttocks, though mercifully they left more to the imagination out front. Eric suddenly caught himself staring at his brother's booty, remembering the feeling of those cheeks in his hands... Shaking it off, Eric coughed, embarrassed, though he didn't blush at the drop of a hat the way his brother did. 
        "Uhh, let me fill my water bottle and we'll get started."
        "'Kay."
As he moved to one of the several water fountains around the floor, Eric silently gave himself shit for that momentary distraction. So it had been a while since he'd gotten any. So he hadn't masturbated since Wednesday. That was no excuse not to keep it in his pants in public! He was in the process of writing it off as a fluke, when he screwed the top back on his bottle and turned around. Milo was doing some stretches, facing away from him, legs spread a bit, reaching down towards one foot, then the other, his tail wagging slowly behind him. Despite himself, Eric's eyes locked onto that butt again, remembering the first time he'd taken his brother from behind, how tight and hot and - 
        "Fuck!"
That bit hadn't been in his head. Unintentionally embarrassing Eric further, Milo looked behind him without standing up straight, the earnest look on his face making it clear his thoughts were nowhere near his brother's. 
        "What? You okay?"
        "Oh, I, uh - no, it's fine, I just, uh, I remembered I forgot to set the DVR before I left, wanted to record the - the game."
To his immense relief, Milo did not ask what 'game' he was referring to, just nodded politely while standing up properly. Trying not to let his feelings show on his face, Eric gestured towards the line of machines on their right. 
        "R-right, let's start with some cardio, okay? Get warmed up before the weights."
        "Sure thing."
Eric let Milo go on ahead, forcing himself to look at the back of Milo's worn Trogdor the Burninator shirt, taking deep breaths. Okay, maybe he needed it more than he thought. Jeez. He shook his head again, silently sending a 'give me strength' to the heavens. He swore, if he got a hard-on in these shorts, he would never be able to show his face here again. Which was fair, really, given that if he was caught actually [i]trying [/i]any of the things running through his mind, they'd never [i]let [/i]him.

The cardio section consisted of stationary bicycles, treadmills, stair-climbers, and a few rowing machines, one of which was being used by a buff cheetah femme with a cast on one leg. All of them were oriented the same way, facing a row of televisions hanging from the ceiling, each labelled with a little numbered card, each set to a different channel, and each and every one completely silent. 
        "I forgot to mention before we left, but you see that little dealie stuck on the machine, here?"
He gestured to a small electronic device clamped onto one of the hand grips on a treadmill. There was one attached to every machine in the area.
        "If you bring headphones, you can plug them into this thing, and use the buttons here to control the volume and which TV you're listening to. But it looks like there's nothing on any of the channels they've got these things on, so it doesn't matter anyway. Here, you use this bike; I'll take this one."
Normally, Eric preferred to use the treadmill, actually, wasn't much of a biking guy. He didn't have any particular reason for suggesting that they use the bike over any of the other pieces of equipment... except that it would involve the least movement in the gluteal region, and they would be side-on to each other. Maybe if he had a few minutes to calm down without Milo being all showy, he could get himself under control. He took a moment to show his brother how to adjust the bike to his liking, and then they were off, metaphorically speaking. 

They pedaled in silence for a short time, but eventually, boredom got the better of them.
        "So, Milo, how's Gela?"
The younger canid immediately gave his brother an untrusting sideways glance.
        "What do you mean?"
        "You know, how's she doing, what have you two been up to lately? Ever since you and her started this totally-just-friends thing, you barely say a word about her."
Leaning over, he regarded his brother with an exaggeratedly suspicious expression.
        "It's almost like you've got something to hide..."
Scowling at his brother, the younger shepherd muttered under his breath before responding.
        "Oh, yeah, because if I'm going to be hiding something, it's going to be my [i]normal[/i] relationship."
        "So you admit it's a relationship then?"
        "Oh for - shut up, Eric, you know what I mean."
Quite enjoying himself, finally able to think of his companion as his brother instead of his fuckbuddy, Eric forced himself to remain deadpan.
        "Is she pregnant, Milo?"
        "[i]What?![/i]"
        "You heard me. Is that girl carrying your pups? Is that why you've been so stressed and distant lately?"
This time, as Milo looked over at his brother again, the expression on his face was a combination of embarrassment and indignation.
        "I - Jesus, Eric, I don't even know if rodents and canines can[i] have[/i] kids!"
        "Oh, so you're trying, but it hasn't taken yet."
        "What?! I... oh, you piece of shit."
The younger shepherd finally having figured it out, Eric burst out into friendly laughter.
        "Oh, God, Milo, you should have seen your face. Fuck, that was priceless. For a second there, you looked so horrified, I thought you really [i]were [/i]gonna be a dad, and I'd stumbled into a secret."
As he started laughing again, Milo stopped pedalling and gave him a Look, though it was hardly as effective as when Anne did it.
        "Yeah, yeah, yuk it up. I'm so glad my life is so entertaining to you."
        "Heh, heh, heh... well, what can I say, Milo? I'm a son of a bitch." 
They kept up their imaginary bike ride for a short while, and then Eric spoke up.
        "Seriously, though, you treating her well? I still feel weird about being the guy on the side, but if you say you're not official yet, I believe you."
Milo's ears lowered ever so slightly and he blushed.
        "Y-yeah, I'm doing my best. Things haven't really changed, except that now sometimes we, uh, d-do The Deed."
He was clearly trying to sound casual, but his voice trembled as he said it, his cheeks burning brighter. Eric said nothing, giving him a pass this time.
        "Didn't you say her birthday was this month? You gonna get her something nice?"
        "Yeah, man, of c-course, I got something really nice lined up. Umm... what about you? You seeing anyone? Um, I mean apart from..."
He trailed off, and Eric didn't blame him, assuming that 'Annie and I' was the missing end to that sentence.
        "Eh, not really... I mean there's this girl I see sometimes, but it's definitely not serious, not going anywhere."
Milo nodded, though he didn't really understand why his brother would continue such a relationship. They continued pedalling in silence for a while longer, working up a nice sweat before the fifteen minutes Eric had suggested had elapsed. 

Leaving the cardio section behind, the Thompsons wandered over to the weight training area. There, Eric and Milo found a bench and tried out some free weights, talking casually while they tested different sizes and then started various exercises. Since they'd been cold to each other for several days, they briefly discussed the goings-on in their lives over some light arm curls. Milo complained about the complex direction one of his classes in school was taking, while Eric talked about how he was having the opposite problem with one of his classes, which was being too [i]easy[/i], teaching only things he already knew. Then, of course, being Eric, he turned to a feline girl with a tight rear as she passed the brothers, and invited her to the gun show. She giggled and said she'd have to take a rain cheque, and Milo shook his head, silently jealous of his brother's ability to remain casual around the opposite sex. It occurred to him for a moment that perhaps the reason he liked Gela so much was that she basically behaved like a guy. Then, taking that thought even further, he blushed, and banished it from his mind, looking around for a distraction.
        "Uhh, hey, Eric, what's this thing?"
        "What, that? That's the bench press. Haven't you seen it in movies? You just lie down there on the flat bench, lift the bar there off the frame, and then do reps until you're done."
        "Ohhhh, that thing. Okay, right."
        "It's supposed to be [i]great [/i]for your biceps."
Eric grinned and flexed, though it wasn't as showy as some of the men in the room; as a soccer player, Eric preferred agility and stamina over raw brute strength, though he was still fairly nicely toned. Suddenly remembering the first time he'd run his hands over his brother's abs, Milo blushed and focused on the bench.
        "Uhh, the little sign here says it's good for your pectorals, actually."
Dropping his arm and looking embarrassed, ears lowering slightly, Eric averted his eyes and frowned.
        "Oh. Right. That's what I meant to say. Great exercise for your [i]pecs.[/i]" 
Milo shrugged, looking uncertainly at the weights designed to go on the bar.
        "Well yeah, if you don't [i]crush [/i]yourself first..."
        "Heh, there's where your spotter comes in, you doof. I'll stand back here by the top, and put my hands under the bar. It'll be all you unless you get into trouble, and if that does happen, I'll help you lift it back onto the frame so nobody gets hurt. Nice and easy."
Milo still wasn't certain of his ability to handle the bar, but he found himself reassured by the casual grin on Eric's face.
        "Alright, Eric, let's give this a try." 
 The younger shepherd sat down on the bench and then lay himself down along it, careful to avoid the bar with the back of his head. Eric began to fiddle and adjust with the weight plates, though it was hard to see from Milo's position. 
        "Let's see, I'll start you off a little low, see how you do with that."

As it turned out, that setting was actually a little [i]too [/i]low for Milo, who found to his surprise that he could easily lift the bar, barely needed both hands. Eric increased the amount of weight, and it proved to be just right for Milo to feel the burn while still keeping it under control. So they stayed with this setting, and the elder sibling began to count out the reps, giving encouragement to his brother as necessary. This went splendidly for Milo, who began to consider joining Eric here more often... until he noticed something. A very specific scent in the air. For a couple of seconds, he couldn't identify it, frowned as he racked his brain, but then he took a deep breath thanks to his exertions, and his eyes widened slightly. Looking 'up' with his eyes, trying not to be too obvious about it, Milo saw that in order to be in position to spot his brother, Eric was standing very close to the end of the bench. The height of the bench meant that Eric's crotch was just behind and slightly above his brother's head. Suddenly, Milo remembered his brother mentioning in passing one day that he didn't shower in the morning on days when he went to the gym, since he was going to do it afterwards anyway and he didn't want the soap and shampoo from the extra washings drying out his fur. Milo needed no more convincing, but that did explain it. He was smelling his older brother's natural canine musk. Normally, a good washing would minimize the strength of the scent, so it wasn't very strong on most civilized morphics. It only tended to get stronger when, as now, the male in question worked up a sweat... though pop culture made it seem like the only activity that actually triggered it was having sex. Milo had had trouble identifying it at first because he usually encountered this smell in a bedroom, while he was doing The Deed with his brother. Shivering, he tried to ignore it and focus on the exercise, focus on the mild ache in his muscles, focus on [i]anything [/i]else, but with his proximity to Eric's junk there was nothing he could do to avoid the scent, and very little he could do to prevent the fantasies that began to play in his mind, imagining Eric suddenly whipping out his length and helping Milo secure the bar even as he slid his penis into his little brother's mouth for an upside-down BJ. 
        [i]No! Think about something else, [/i]anything [i]else!
[/i]Locking the bar into place, Milo is shocked to discover Eric at the other end of the bench, sliding his shorts down without a word. He puts up no resistance, though, and only moans and blushes when his brother joins him on the bench and slides his rigid prick into Milo's rear, balls-deep. Somewhere across the open floor, a woman gasps.
        [i]Jesus! Not like [/i]that! [i]Where did that even come from?! Oh fuck, I can't have a boner now! Not in these shorts, not flat on my back!
[/i]Milo bit his lip, wondering whether his current state of arousal was visible yet, but dared not look down his body for fear of giving the game away. Looking up towards his brother, he thought he saw Eric staring pointedly in the direction of his crotch before he looked away, face unreadable from this perspective. The younger shepherd briefly imagined a crowd of people circling the bench, pointing and laughing at an obvious erection tenting out his shorts while he was inexplicably forced to continue pumping iron. 
        [i]Dammit, that's counter-productive. Okay, I need an out, I need to get my nose away from Eric's fucking balls...
[/i]A muscle in his right forearm gave a particularly uncomfortable twinge, and he suddenly saw his exit strategy. Suddenly, he let his right arm dip, exaggerating the pain he'd just felt, going as far as to make it tremble slightly, as if barely able to hold up the weight.
        "Eric!"
Suddenly Eric's hands were there, gripping the bar tightly, confidently, holding it still.
        "Whoa there, little brother. I gotcha. It's alright. Let's just put this away, just like I said, okay? Upppppp..." 
With the other canid's "help", Milo lifted the bar back onto the jutting notch in the frame, carefully putting it in place so they could relax. As Milo let his hands fall back down to his torso, he resisted the urge to clap his hands over his groin. The other shepherd's concerned face suddenly blocked out the overhead light as Eric leaned over his brother to look him in the eye.
"You okay there, Milo? Maybe that was too much weight after all."
Suddenly, Milo felt oddly bad for misleading his brother.
        "N-no, I think that was a good weight, I just, uh, slept on that arm funny last night, it's been achey all day. It should be f-fine for next time."
Closing his eyes, he swallowed a whimper, certain Eric was going to call him out, as he was no better at lying to his brother than his sister. To his surprise, the elder dog just nodded slowly, and stood back up straight. 
        "Okay, little guy, if you say so."

After Eric helped Milo up (and Milo 'discreetly' checked the status of his penis when Eric's back was turned), the Thompson brothers tried out several other exercises, with Eric explaining (mostly accurately) how each of the machines or weights was used and then using them in turns, until finally, panting like ferals, they decided that they'd seen enough different exercises for now, and headed over to the drinking fountain set into the wall to refill their water bottles. Milo gratefully re-hydrated while his brother waited, his tail wagging eagerly. When they moved on to actually filling up their bottles, a friendly voice greeted them.
        "Hey, it's you two again!"
Turning to look, Milo found himself blushing again, as he discovered the border collie from the bathroom, coming to refill his Canucks bottle. Thankfully, he now wore a sleeveless T-shirt and a pair of track pants instead of absolutely nothing at all. His fur was a sweaty mess, and would need a shower and a good combing, making it clear that he'd been working at least as hard as the Thompsons. Holding up his bottle, he grinned.
        "Thanks again for getting my bottle for me, mate. It's always super awkward, getting things from under a bench guys are sitting on."
Milo discarded the immediate instinct to question the man's judgement if he [i]hadn't[/i] thought their first meeting was awkward, and grinned, hoping his blush wasn't too obvious.
        "Oh, hey, it was nothing..."
Eric stuck his hand out, smiling. It was impossible to read whether he was aware of his brother's discomfort or not.
        "Hey, I'm Eric, this is Milo. I've been coming here a while and don't recognize you, you new in the area or just to the gym?"
Accepting the outstretched hand and shaking vigorously, the other dog smirked crookedly.
        "I'm Keith, good to meetcha'. And it's a little of both, actually. I just moved, but I was already in the area, just switched to a better apartment. This gym just happens to be a lot closer to my new place than my old place, so it's easier to force myself to get up and go."
        "Oh yeah, I know [i]exactly[/i] what you mean. I used to put it off all the time before they built this one. It's not exactly close, but it's a couple towns closer than the next one, so I get out a lot more."
The collie grinned at Milo.
        "What about you, you a regular too?"
        "Oh, uh, no, actually this is my first time here, Eric invited me out today."
His grin widening, Keith switched his gaze to the other Thompson.
        "Well, isn't that nice of you?"
Eric chuckled softly.
        "What can I say? I've gotta get him out of the house somehow."
They laughed together and began comparing notes about the gym. Milo didn't really [i]know [/i]anything about the place, so he mostly just stood there, nodding and smiling in what he hoped was a pleasant manner. Bored out of his skull, he let his mind wander, at least until it conjured the image of himself on all fours, stark naked, Eric kneeling behind him and energetically rocking his world, while still casually talking to the Australian stranger. Swallowing a whimper, wishing his brain would spontaneously generate a fantasy where he was the dominant partner once in a while, Milo tried to pay more attention to the conversation. Fortunately for him, it seemed it was wrapping up, with the collie looking at his wristwatch and sighing before speaking up again.
        "But yeah, I'd better get back to it, I gotta get finish up here in time to get home and make dinner." 
        "I hear you. Good talking to you, though."
        "Same here."
Keith paused, eyes switching back and forth between the other dogs for a moment.
        "You know, it's good to see couples out doing things together, shared hobbies and all that."
Milo froze in place, deeply embarrassed, practically horrified. Beaming at the German shepherds, oblivious to his mistake, the border collie nodded as he left them.
        "You two look cute together, too."
Milo's ears lowered to his skull as Eric, to his surprise, did nothing to correct the mistake, returning that smile like nothing was out of the ordinary. 
        "Later!"
Heading over to the weight training section the brothers had just left, Keith gave a little wave and then turned his attention to the exercise equipment. Milo stood there stunned for a few seconds more, and then he finally managed to shake it off. 
        "He - he... he thought we were... oh God, Eric, he thought we were [i]boyfriends![/i]"
Snorting in amusement, Eric shook his head, still grinning.
        "Gee, Milo, whatever gave you [i]that[/i] idea?"
        "This isn't funny, Eric!"
        "Oh, it's pretty funny." 
        "Eric!"
By now, Milo was on the verge of actual panic, when he felt his brother's strong hands on his shoulders.
        "Hey, chillax, little br- "
Here he looked around, to make sure Keith wasn't within earshot.
        "...Just relax, okay? It's not a big deal. It's not like he's rushing home to post about it on Facebook. He doesn't even know our last names, we're just 'the nice gay guys he met at the gym today.'"
Milo still looked uncertain, but his muscles relaxed visibly. 
        "B-but what if he sees us in public?"
        "I don't know, we correct him and laugh awkwardly about it. It's not going to be a problem, you hear me? I don't know anyone else who comes to this gym, and I haven't seen any of your cronies around either."
Eric began to rub his brother's shoulders with his thumbs, musing for a moment that this sight wouldn't do anything to discourage Keith from his assumption. The younger canid mulled it over for a moment, and then sighed and nodded.
        "Okay, Eric, I trust you."
As his brother released his grip on his shoulders, Milo shrugged apologetically. 
        "Hey, uh, can we get out of here? I'm really not feeling up to more after that."
To his deep relief, Eric nodded without even making a wisecrack, patting him on the back as he answered.
        "Sure thing, dude. You worked pretty hard today already. Let's hit the showers."

Shortly thereafter, Milo found himself back in that changeroom, this time feeling achey instead of cold as he stripped out of his sweaty clothes and stuffed them in his bag. Taking the towel Eric had suggested he pack with him, he walked the short distance from the locker to the showers in the buff, blushing fiercely and trying not to look around, paranoid that someone was staring at him. As he walked, he made a physical effort to keep his ears upright and his tail in a neutral position. There wasn't much he could do about the blushing, but he'd be damned if Milo Thompson wasn't going to keep his dignity. He'd noted as they first walked in, to his immense relief, that instead of the flat tiled wall with interspaced showerheads, as he'd been expecting, the shower facilities in this gym were actually separated into enclosed cubicles, with opaque plastic curtains serving as privacy barriers. The shower area was quite a bit wider than the open entryway between it and the locker area, and Milo walked into an unoccupied stall off to the side, where no one would be walking past. Hanging his towel up on a peg jutting out of the cubicle wall near the curtains, out of splashing range, the lanky teen turned on the water and was pleased to find it spraying with a decent amount of pressure, and heating up almost instantly. Stepping under the downpour, closing his eyes and just savouring the feeling of water against his fur, Milo sighed happily. This was [i]much [/i]better than showering with a bunch of strangers, staring at the wall and blushing. He also noted, smirking, that 'dropping the soap' was a non-issue, as the wall of the cubicle had a liquid soap dispenser with a starburst label boasting 'Good for skin [i]and [/i]fur!'. The shepherd got his hands all lathered up and went to work, starting with his head, rubbing stress out of his scalp and ears as he worked the shampoo in, then stuck his head under the water so he'd be able to see for the rest. No sooner had he done this, though, when he heard the sound of the curtain in the stall jostling to the side. Turning to face the front of the stall, he realized that he couldn't see anything from the water still in his eyes, so he held out his hands in front of him, blush returned with a fiery vengeance.
        "Shit! Occupied, occupied!"
To his shock, the blurry outline of a man didn't apologize and hastily close the curtain, he [i]stepped into [/i]the stall with Milo and closed the curtain behind him. These few seconds it took his eyes to clear had suddenly become some of the most stressful of the day, but when he finally managed to blink away the water, he relaxed, leaning against the tile wall to wait for his pulse to go back to normal as he glared at the other male.
        "Fucking hell, man! You can't just waltz in here like that!"
Eric Thompson laughed softly, hanging up his own towel over Milo's.
        "You know, it's funny, I seem to remember you doing the [i]exact same thing [/i]the day we first did The Deed."

Glaring at his older brother, who seemed entirely unbothered, Milo crossed his arms. He was fairly certain no one would be able to hear them over the shower, but he still tried not to raise his voice.
        "The hell are you doing in here, anyway? You - you can't just come into the shower with me, man, people might get, you know, the wrong idea."
The elder shepherd just chuckled as he stepped forward, a certain look in his eyes, a certain smile on his lips.
        "Well, little brother... who says it's the wrong idea?"
Swallowing, his shock showing clearly on his face, Milo pressed his back against the wall next to the faucet control, unable to back away as Eric strode forward, putting his hands on the wall on either side of his brother, that same smile getting wider.
        "[i]What?[/i]" 
Milo shivered as his brother boldly let his eyes roam over his unclothed form.
        "Do I have to spell it out for you?" 
Eric leaned in, his muzzle practically touching Milo's ear, to ensure he would hear these next words despite the breathy whisper he delivered them in. 
        "I [i]want[/i] you, Milo."
The younger dog whimpered, not sure how he felt, whether his protests were entirely genuine or just reflex.
        "N-no, Eric, we can't, not in [i]public![/i] God, wh-what if someone walks in on us?"
        "You planning to invite that Keith guy in here? Nobody's gonna come over here Milo... well, except [i]us[/i]... if we keep it quiet and don't blow our cover."
If there was one thing Eric was [i]not[/i], it was forceful. He had yet to lay a single finger on his brother, and Milo knew if he insisted, Eric would back off. And yet... it had been a few days since he'd had the chance to get off, and with this new information from Anne...  shivering, Milo bit his lip, thinking it over, and then glanced back up at his brother.
        "...Oh, what the hell."
For once, Eric seemed taken by surprise as Milo leaned forward, reaching up to embrace his brother as he pressed his lips against the elder shepherd's. He recovered quickly, though, returning the embrace as he hungrily kissed Milo, grinding his pelvis against his brother's. After a moment, he broke it off with a gasp, grinning excitedly.
        "God, I don't know what it was today, but as soon as I saw you in those shorts? [i]Fuck[/i], man, I never really saw it visually before, you know, it was just a hands-on thing, but, uh, you've got a really nice ass, Milo."
As he spoke, his hands slid down Milo's back to firmly grip his buttocks. Shivering, the younger canine pressed back against his brother's hands.
        "You think that's bad? I - I could [i]smell [/i]you while I was on the bench press. It was driving me [i]crazy![/i]"
Eric chuckled, grinning.
        "Ohhh, [i]that [/i]would explain it..."
Remembering his worry that his arousal might have been visible, Milo blushed. 
        "Explain what?"
Silence.
        "Explain [i]what?[/i]"
The elder shepherd just laughed again, giving his rear a squeeze again.
        "You need to learn to relax, little brother."
 With that, he leaned in and kissed the other canid again. Milo moaned and held Eric tighter as he eagerly returned the kiss, feeling his brother's penis growing longer and harder pressed against his body, knew that Eric was feeling the same thing. He focused rather intently on his tongue writhing and rubbing against Eric's, the feeling of someone else's hands on his body. His mind hadn't quite moved on to the next step when he suddenly felt his brother's fingers poking at his backside. 

Breaking the kiss with a yelp, he instinctively grabbed Eric's wrist.
        "E-Eric?"
His older brother flinched, embarrassed.
        "Oh - I'm sorry, Milo, I shouldn't have [i]assumed[/i]..."
Realizing this was the point to try and put his newfound comfort into practice, Milo grinned self-consciously and shrugged.
        "W-well, I suppose it's okay if you wanna be the top, I know you're more used to that..."
        "You sure? Cause I wouldn't mind..."
        "No, no, it's fine, Eric, I j-just didn't know what you were doing."
Okay, so it wasn't admitting he really liked to take it in the can, and it wasn't really [i]asking [/i]Eric to do it, either, but progress was progress. Bringing his mind back to events at hand, Milo whimpered quietly as he felt his brother's hand teasing under his tail again. 
        "Well, I don't bring lube to the gym, Milo, no matter what the cliché says. And even if I did, my stuff is water-based, so it would wash away in here. So what we need to do instead is get you nice and relaxed back here, like stretching before a race." 
Eric's persistent fingers defeated the stubborn muscle that protected Milo's rear entrance, the younger shepherd swallowing a moan as his brother's fingers slid inside him. 
        "[i]Ohhh...[/i] A-alright,[i] [/i]Eric."
There, Milo held his brother tight, closing his eyes and focusing on the sensations in his rear, the way Eric's fingers gently pushed into his body, teasing him from the inside. The elder brother continued stretching him out, occasionally causing a twinge of pain when Eric tried to go too far, too fast. These mistakes were always quickly rectified, and always quietly apologized for. Milo had been worried at first that Eric would stumble across that [i]spot[/i], the one that put such delicious pressure on Milo's prostate, and he'd go off right off the bat, rather firmly freeing the cat from the bag. But now he found himself pushing back against Eric's fingers, wanting more, biting his lip to suppress whimpers of need. As his penis throbbed in empty air, a shining drop of precome emerging from the tip only to be instantly washed away by a dash of water, Milo swallowed his pride and decided to be a bit more proactive. Once again he stopped his brother, pushing Eric back and breaking off their embrace. 
        "That's enough, big brother... I - I think I'm ready..."
Blushing deeply, Milo turned around and bent forward, bracing his hands against the tile wall under the spout as he lifted his trembling tail skyward. 
        "P-please, Eric... I want it..."
The elder Thompson just smiled as he slowly moved forward. Closing his eyes again and trembling with anticipation, Milo shivered, despite the ever-present warm water. Once again he fought the urge to lower his ears to his skull in shame, remembering what Anne had taught him.
        [i]It doesn't mean that I'm his bitch, or that I'm in love with him, or anything! It just means I understand what makes me feel good and -[/i]
To his embarrassment, he let out a gasp as he felt his brother's hands touching him again, placed on his sides, just above his hips, and sliding forward to his fuzzy stomach. As he stepped forward, spooning against the other dog's back, Eric leaned forward and gently bit down on the back of his brother's neck, the location of a loose patch of extremely sensitive skin. Milo groaned quietly, savouring this contact. The way they were standing, the wide spread of the water from the faucet fell across both of them evenly, running down their bodies, dripping off their saturated fur, keeping them nice and warm. They had to be careful to position their faces outside of the streams, though, to make sure they could see and/or breathe. Finally, one of Eric's hands left his stomach, and very shortly thereafter Milo felt his brother's rigid prick nudging at his anus. 
        "Doing it in here's gotta be better than spitting on it, right little guy?"
Milo responded with a rather forced chuckle, nervous about the immediate future. 
        "Okay, Milo, this is probably gonna be at least a little rougher than usual, but you can still call it off at any point if it hurts too much."
        "Thanks, Eric."
Milo shivered as he felt more pressure against his entrance.
        "Ready? Alright, I'm starting..."
[i]
[/i]Just as Eric had warned, Milo felt a [i]lot [/i]more pressure than usual before the sudden moment where his sphincter relented and allowed entry to Eric's penis, which boldly pushed forward, embedding fully half of its length in the shepherd's warm passage, which clenched down, on the fringe of pain, at the sudden intrusion. Whimpering, Milo trembled, but bit his lip and rode it out. When Eric saw that his brother had relaxed slightly, he slowly pulled back.
        "You okay there, little brother?"
        "Y-yeah, I'm fine, just took a little g-getting used to. Um, don't they say only butt sluts can take it without lube?"
Milo could practically [i]hear[/i] his brother's eyes rolling in his response.
        "Who says that, exactly? And why do you care? Milo, you've gotta learn to relax, there isn't a panel of experts grading everything you do in here, nobody's judging you!"
Finding those words surprisingly encouraging, though perhaps not in the exact way Eric intended, Milo relaxed, stopped worrying what his brother would think of all this, closing his eyes in anticipation as Eric spoke up again.
        "Now then, if you're good to go..."
Immediately afterwards, Eric pushed forward again, hilting himself in his brother's rear and causing both brothers to grunt appreciatively. After a moment, seeing that all was still well, Eric pulled back again, and this time kept moving, starting the cycle of pulling and thrusting that had Milo's toes curling up on the tile floor. As his brother's cock rubbed along his inner walls, Milo held his breath at first, afraid that Eric would find that spot inside him that would turn him into a moaning, oversensitive mess. After a moment, though, he let his breath out - mostly because he [i]needed [/i]to, given the energetic nature of the moment, but he felt pretty confident that Eric couldn't push his button from this position, the angle wasn't right. Without having to worry about humiliating himself before he could explain, Milo moved his head forward, straight under the cascading water, to douse himself in warmth as he enjoyed the ride. Eric was holding him pretty firmly from behind, spooned up against the younger canine perfectly. With a groan, Eric began to mutter in his brother's ear.
        "Nnngh, [i]fuck[/i], Milo... still tight as a virgin, but you take it like a champ... God, it's [i]amazing[/i] how much I missed this after only a couple weeks without." 
Milo, meanwhile, had felt their sister's fingers inside him since the last time he'd been with Eric, massaging his prostate and bringing him to a toe-curling orgasm, but somehow, it just wasn't the same as having a nice, thick cock pushed inside him, stretching him out, filling his tight passage... the younger canine whimpered, blushing. It was nice that he was 'allowed' to enjoy being submissive now, but it sure was hard to avoid the instinct for shame every time he had a thought like that. It helped, though, when he remembered how [i]good[/i] it felt; leaning against the wall, his brother thrusting into him again and again, feeling Eric's warm, panting breath on his back, those strong hands gripping his shoulders... and of course that rigid penis rubbing and sliding against his inner walls. As his brother bit down on that sensitive spot again, gently rubbing the loose skin between his front teeth, Milo's head perked up, and he resisted the impulse to moan out loud, fearing someone would hear him. 

They continued energetically rutting like that for a while, with Eric relieving some tension and stress, and Milo just enjoying the experience in a new way. It really [i]did [/i]feel more enjoyable now that he wasn't worrying over every little thing and second-guessing himself. Then, Milo felt his brother's arms pull back on his torso, making him stand up straight and lean back, which the younger shepherd did not resist, leaving his arms hanging at his sides; now that he couldn't reach the wall to lean against it, he didn't know what else to do with them. 
        "E-Eric?"
Milo looked down, blushing, when no answer greeted him. Now that a major stream of water was directed towards his chest, it rushed down his torso like a river, parting as it reached his erection like it was a big rock before a section of rapids. As he watched, his brother's hand slid around to his stomach, creeping down obviously towards his groin.
        "You know, little brother, this isn't just about me. Don't want you to think I've forgotten about you." 
Milo bit his tongue to keep from groaning as Eric's fingers slid around his prick, giving him a gentle squeeze, but not moving otherwise. Eric cleared his throat, and to his surprise, Milo realized from the sound of his voice that his brother was embarrassed.
        "I, uh, I know that sometimes I can get carried away with teasing you, but I also don't want you to think that I'm just trying to take advantage of you or anything..."
There was a moment of silence, neither brother saying anything, Eric having stopped even his thrusting. When the moment passed, he coughed and then spoke up again. Milo could practically hear[i] [/i]the blush on his brother's cheeks.
        "So! How do you, you know, want this to go down? I could give you the reach-around now, or I could suck you off afterwards; the blowjob'd probably feel better, obviously, but you'd have to wait until I finished, and I don't wanna give you blue balls." 
The smaller dog shivered in his brother's arms; he was so turned on by this point he could barely stand it. 
        "Ohhh man, Eric, I - I can't wait for it, I'm dying here, please..."
Milo swallowed a moan as his brother gave his erection a squeeze, and then began to stroke, moving slowly along his shaft. 
        "Relax, Milo, you know I've got your back."

As Milo shivered under his brother's surprisingly gentle grip, Eric leaned them both forward again, letting Milo get his hands back on the wall. The younger shepherd bit his tongue in anticipation as his brother adjusted himself and prepared to pick up where they left off. He managed to keep silent as Eric pulled back for the first time, but despite his best efforts, he was unable to contain the moan that ensued when his big brother pushed home again, hilting himself in Milo's rear. He quickly found himself beyond the point of caring, though, as Eric began thrusting in earnest again, pushing inside Milo again and again, now accompanied by his brother's hand working his prick over expertly. Belatedly remembering that there was a reason for keeping quiet aside from his dignity, Milo closed his mouth tight and cut off the whimper that he felt coming as Eric continued his ministrations. The older shepherd hadn't complained about the noise because he, too, was beyond the point of caring, and because he'd been fighting to contain some pleasured cries of his own. 
        "Ohhh, [i]fuuuuuck[/i]...  Goddamn, Milo..."
Eric trailed off, thought forgotten, as he continued thrusting into his brother, who by now could feel the end approaching much faster than he'd expected. He decided to try and fight it, and while he probably wouldn't be able to suppress a moan if he failed, he promised himself that at the very least, he wouldn't yell 'Dame!'.  Leaning in against the wall, placing his cheek flat against the warm tile, Milo gasped and sighed as quietly as he could, pushing his hips back to meet Eric's thrusts even as he tried to hump into his brother's hand to make himself feel even better. When he found he had to speak, he hissed his words to avoid crying them out.
        "Ohhh... oh, God, Eric... I - I'm so close, I'm gonna come..."
Growling into Milo's ear, shaking with arousal, Eric's voice sounded just under control as he managed to reply.
        "I'm r-right there with you, Milo... don't f-fight it, let's come together..." 
Clapping a hand over his muzzle as he groaned just from hearing those words, Milo nodded eagerly and closed his eyes, focusing on the glorious sensations. He felt his penis tightening up as Eric stroked him harder and faster than ever, clearly wanting very much to finish the other canine off, leaving Milo shivering in anticipation of what was about to happen.

A few moments passed in general quiet, a few muted whimpers and wet slaps that were easily drowned out by the rushing water. Then, Milo suddenly stiffened, inhaling sharply, and pressed down hard on his muzzle to try to contain the long groan of release he couldn't prevent as the orgasm overtook him. His brother's hand rubbed his twitching, spasming cock just the way he liked it, hard and fast, and Eric was still fucking him from behind with even more enthusiasm. Milo muffled another moan as his prick throbbed and pulsed, spurting his hot, gooey shepherd come into the warm air of the shower hall, before splattering against the shiny tile and almost immediately being washed away to the drain directly beneath them. As he came, Milo was naturally urging his brother along as well; every time Milo ejaculated, he clenched down on the slick passage that currently contained his brother's penis. As he himself was rapidly nearing the end, Eric had taken to much shallower, faster thrusts into his brother's rear, and now, he felt Milo squeezing around him. The elder Thompson groaned and closed his eyes as it grew so tight he could barely move. Leaning forward again and spooning against Milo's back, he grunted, the breath tickling the back of the other dog's neck, while his own cock began to throb deep within his brother's body, signalling the oncoming release. Hovering on the precipice, Eric groaned, and whisper-hissed into Milo's ear.
       "F-f-fuuuuck, here it c-comes, Milo, I'm gonna fill you up..."
Milo was [i]way[/i] past being embarrassed right now, so for a change he didn't care one iota if Eric wanted to say such things to work himself up even more as he climaxed. He felt his brother pull all the way back, only the head of his rigid penis still inside, and then Milo yelped, eyes snapping open, as Eric hilted himself one last time, burying his prick beneath his brother's tail as he flew off the edge into the oblivion of orgasm. Then, there it was; as Eric buried his face in Milo's shoulder to muffle his cries, Milo felt that faint pulse, and then the sudden warmth of his brother's semen inside him, running along his tight passage, oozing into every nook and cranny, filling in the space around Eric's hard, spurting cock. Moaning into his hand again, Milo felt his toes curling up, as his orgasm ended while Eric painted his inner walls with thick jets of wet, sticky come.

The brothers stood there for a while, tongues out, panting like ferals, just resting for a moment after a very different kind of strenuous activity than most of the men who used these facilities. Milo was rather enjoying the closeness he felt like this, Eric's whole body pressed up against his back, his brother's slowly softening penis still inside him, Eric's strong hand still lightly gripping his own deflating manhood, and with the warm water pleasingly running down their bodies, he didn't even feel the uncomfortable sweat in his fur that was usually the one flaw in afterglow. Finally, the older canine broke the relative quiet with a heavy sigh of satisfaction.
        "[i]Jesus[/i], Milo, that one felt like I hadn't come in a [i]month[/i]. I am so, so very glad we're talking again." 
Chuckling tiredly, Milo grinned.
        "Oh, is [i]that [/i]what we were doing? See, [I]I[/I] thought you were fucking me."
Eric laughed once, patting his brother on the shoulder as he let go of the younger shepherd's flaccid cock.
        "Wise-ass."
        "But weren't you just talking about how much you [i]like [/i]my ass?" 
Milo whimpered quietly as Eric pulled out, and then turned around to face the older dog, leaning back against the tile, which now felt cool compared to his body heat. Putting his hands on his hips, Eric smirked. 
        "See? I missed this."
Impulsively, Milo reached forward and grabbed his brother's shoulders, pulling him in close for a kiss. The elder shepherd stiffened, resisting for just a moment, before relaxing and going with it, pressing his lips against his brother's, holding him close and kissing him tenderly, gently, no particular urgency. It only lasted a few moments before they broke it off and Eric belatedly remembered that perhaps they [i]should [/i]have felt some urgency.
        "Jeez, we've been in here a while now. I hope nobody cares that we've had the shower running this whole time."
Milo shrugged.
        "Eh, it was going to be on anyway, just not with the same people." 
Eric turned towards the towels at the entrance of the booth, but Milo paused, feeling a familiar sensation. Blushing, he reached down and gingerly touched a couple of fingertips to his recently-vacated backside, feeling Eric's still-warm come slowly leaking out.
        "Ummm, Eric? I, uh, I need to get cleaned up again..."
Pausing midway through reaching for his towel, Eric glanced back at his brother and then shrugged.
        "Actually, I could use a wash myself..."
Feeling the pressure of their delay, as though someone was standing outside looking at a watch and glaring, wondering where they were, the Thompsons quickly moved back to the water, getting soap from the handy dispensers and scrubbing the sweat and come out of their fur. As Eric helped him clean the center of his back, it occurred to Milo that normally, asking someone to help scrub your back was a subtle invitation issued [i]before [/i]you had sex with them. Once they felt clean enough, they turned off the water at last and grabbed their towels. Now, given that they were covered in water-holding fur, towels don't really do morphics a hell of a lot of good, but they were able to at least get themselves slightly less drenched so that the fur dryers - phone booth-sized capsules with warm air jets on all sides - wouldn't have so much work to do. Eric peeked from behind the curtain, and indicated to Milo that the coast was clear, there was no one else in the shower area. Trying his best not to look guilty, forcing his ears upright and his tail anywhere but between his legs, Milo tugged the curtain aside and began walking quickly towards the wall of dryers and his perceived freedom... just as Keith the border collie emerged from around the corner, towel slung over his shoulder, eyes widening as he took in the sight of Milo exiting a shower stall with Eric right behind him.

All three canines froze in place for a moment, the world seeming to stop everything but the water dripping from the German shepherds' bodies in an attempt to hold onto another awkward moment for its private collection. Milo's eyes darted from his brother to the collie as his ears betrayed orders and flattened against his skull with a [i]fwip[/i]. It was obvious that they'd [i]at least [/i]been showering together, there was no excuse they could give to explain this away, at least none the petrified shepherd teen could come up with. Keith's eyebrows raised slowly as he looked back and forth between the Thompsons, his expression otherwise unreadable. Eric seemed surprisingly calm, though Milo could see the tension around his mouth that indicated he wasn't particularly pleased with this situation either. After a few moments that felt like about a thousand years, Keith suddenly broke out into a very wide smile, grinning at the brothers with a knowing expression. When Milo looked to Eric, confused, he saw that his brother was also smiling, and before he could react to the movement, the older shepherd suddenly reached out a hand and gave Milo a single smack to the ass, causing him to jump slightly and give a yelp. Without a word being spoken, the smiling collie nodded to each of the shepherds and then brushed past them, heading into one of the stalls and tugging the curtain in place. A hopelessly confused Milo looked to his brother, who just put a hand on his shoulder and guided him towards the dryer booths. 
        "B-but..."
Eric cut him off with a low whisper.
        "Just play it cool, man, it'll be okay."
There was no one else using the dryers when they arrived, so Milo felt confident enough to at least whisper. 
        "Eric? What - why didn't he..."
Seeming perfectly at ease, Eric smirked as he hung up his towel and stepped into a booth. Glancing around to ensure their privacy, he responded in an equally hushed tone.
        "Relax, Milo. Think about it; he thought we were an item earlier, remember? And we didn't correct him. To him, we're not -"
Here he took one more look around to make sure no one was listening in.
        "...He thinks we're boyfriends, not brothers. As far as he knows, he just walked in on gay dudes catching a moment together in public, not a pair of brothers... well, doing the same thing."
        "S-so we're in the clear?"
        "Of course, that's why he didn't say anything. He wouldn't want anyone ratting [i]him [/i]out if he was making time with someone." 
Letting out a sigh, significantly more relaxed, Milo shook his head. This whole 'secret sex life' thing was really stressful sometimes. And yet...
        "...Wait, what was the spanking about?"
        "You know, I don't think it counts as a 'spanking' if there's only one..."
        "Dammit, Eric..."
The older shepherd chuckled.
        "Come on, Milo, did you really not see that? I was letting him know which one of us wore the pants! 'Aww yeah, I tapped that.'"
 Milo blushed [i]fiercely [/i]at that, and his jaw literally dropped open in shock.
        "What the [i]fuck,[/i] Eric!? Y-you let a [i]stranger [/i]know that you - that I - oh Jesus, I can't believe you did that!"
Milo imagined Keith in the shower, with that knowing grin on his face, chuckling to himself as he pictured the slender shepherd being taken by his larger, more muscular lover, and just barely suppressed a whimper. He was already uncomfortable with the idea that two people he trusted implicitly knew he'd taken it in the can, but a stranger? Naturally, the elder Thompson winked, as though it were no big deal.
        "Oh, I think this is [i]entirely [/i]in keeping with my past behaviour. Offering him sloppy seconds, now [i]that [/i]would be unbelievable."
Crossing his arms and pouting, his cheeks burning with embarrassment, Milo tried to kill his brother with an angry glare.
        "God, you're [i]such[/i] an asshole sometimes."
        "You know you love me. Now, if you'll excuse me, it's getting fucking cold out here, and being soaking wet isn't helping."
Eric stepped into the booth and closed the door behind him, the whirr of the heat jets drowning out any further protests Milo might try to make. The younger sibling stood there, dripping, for a few moments longer, still shocked. Eric had done a lot of shit over the years - they were brothers, it happened, and Milo was certainly no saint himself - but this was too far, at least as far as Milo was concerned. Sighing and stepping into a booth of his own, as Eric had been right about the temperature, he tried to shake it off, as Eric so clearly had, but he couldn't help but feel hurt over that. Maybe he would feel differently if [i]he'd[/i] been the top and Eric had somehow indicated [i]that[/i] to Keith. Maybe...

The rest of the trip was mercifully uneventful. Once they were nice and dry, the shepherds headed back to the locker room, gave their fur a quick combing (as no morphic worth their salt would leave home intending to shower without bringing a fur comb), and got dressed. Stuffing his workout clothes and towel into his bag, Milo followed his brother out of the locker room without further incident and walked to the exit. On the way there, Milo found himself blushing. He trusted Eric's judgement when he said that he didn't think Keith would tell anyone, but he couldn't help but worry. When the girl in the circular reception area turned and addressed them, he stiffened for a second, sure they were about to be chastised for doing it in public, but she just said
        "Thank you for using our facilities, we hope to see you again soon!"
Milo forced a grin and a nod to the friendly human; Eric thanked her by name (which was prominently written on her staff ID) and gave her a wink, which earned him a rather genuine looking smile. He looked totally relaxed, carefree, as if he hadn't nearly been caught breaking several laws and moral codes, and then betrayed his partner in crime. Milo remained quiet on the drive home, looking out the window and stewing, trying to let it go, but the smack on his butt and the casual way Eric had put it kept replaying in his head. 
        [i]Aww yeah, I tapped that. [/i]
Sighing, the slender dog leaned back in his chair, just thinking. And he would keep thinking all the way home.

A few hours had passed, and things were quiet in the Thompson house. The parents were still out, and the children had made separate dinners and retreated to their rooms. Right now, Eric lay on his bed, listening to music and blasting virtual aliens into clouds of mist in various colours. There came a knock on his door just as he was lining up the sights on a futuristic sniper rifle with an oblivious invader's cranium, and Eric sighed at the interruption. Putting the conflict on pause, he got up to get it, and was surprised to find his brother at the door. 
        "Uh, hey Eric, can I come in?"
        "Of course, dude. Long as you don't mind the mess."
Stepping inside, Milo began to fiddle with his hands, looking a touch nervous. Eric gestured at the TV.
        "You gotta try this one, man, it's [i]sick![/i] I was in the middle of something, but if you want I could save and we could try co-op."
Milo cleared his throat, avoiding eye contact, which put a tiny smile on Eric's lips.
        "Actually, um... look, Eric, I know it's been a while since we, uh, [i]did[/i] [i]stuff[/i], but I'm still kinda worked up after the gym, and, ah, I was wondering if you wanted to, you know... fool around?" 
He seemed as embarrassed this time as he had the very first time he'd asked, though to his credit he managed to suppress his usual blush. Putting down the controller, Eric grinned predatorily and sat back down on the bed.
        "You know, I could [i]use [/i]a break..."
Grinning, he tugged his shirt off over his head and discarded it, then crooked one finger towards Milo, beckoning him towards the bed. As the younger shepherd walked up, smiling shyly, Eric reached out and gently pulled him into his arms, up onto the mattress, so that Milo was kneeling on the bed, sitting in his brother's lap, when they began to kiss. After only a few moments, though, Eric broke it off, leaning to the side with a frown.
        "What?"
        "...Just making sure we locked the door this time."
As Eric began to fiddle with his brother's belt and the fly to his pants, Milo groused, putting his hands on his hips.
        "Dammit, that was [i]one[/i] time, and I didn't even think we were gonna [i]do[/i] anything when I came in."
        "Yeah, well, I'd rather not have this particular history repeat. I swear Anne's like a fucking Jedi or something, sensed a brotherly disturbance in the Force while we were out."
        "What do you mean?"
As Eric successfully opened his brother's pants, he lay down on his back, gently taking Milo with him, to get the other shepherd into a position that made it easier to discard his jeans.
        "I was making a sandwich earlier when she came into the kitchen, and out of nowhere starts grilling me on whether anything she would be interested in happened at the gym. Did she get anything from you? She seemed convinced."
Milo swallowed, suddenly worried.
        "N-no, I haven't seen her since I got back. What did you say?" 
Eric turned onto his side, so Milo wasn't lying atop him, and then pulled him in close, one hand making a beeline for his brother's butt, giving a cheek a nice firm squeeze before he answered, laughing as he did so.
        "I started going into a [i]lot [/i]of detail about my workout routine, which exercises I do, how many reps at what weight, number of calories I burn..."
Milo couldn't help but giggle, enjoying the warmth of the moment almost as much as the mental image. He knew [i]exactly [/i]how Eric would have done it, too, from previous experience; no doubt he'd put on an overeager expression as he went into the boring nitty-gritty of a workout, pretending to be both way more enthusiastic than he actually was and completely oblivious to his sister's boredom. The younger shepherd grinned, shaking his head.
        "Man, I bet she couldn't get out of there fast enough."
        "I'm not sure she bought it, but either way it annoyed her enough to chase her off. Now then..."
He helped his brother pull off his shirt, so that Milo lay on the bed in just his boxers, and then they both worked on freeing Eric from his shorts, so that they were nice and comfortable and ready to get started. 

As they lay back down and resumed kissing, Milo reflected on the fact that he and Eric never used to kiss. Actually, there'd been very little foreplay to speak of, no cuddling or snuggling. Milo had wanted to save his first kiss for a [i]real [/i]relationship, but once he'd shared that milestone with Gela Taylor (not that they were in a relationship yet, of course, he was quick to nervously remind himself), something his siblings had been [i]surprisingly [/i]quick to pick up on, he and Eric had kissed for Anne's benefit on their first 'blackmail' session. But since then, they had taken to including it in their stress relief, which Milo found he rather enjoyed. The last time he'd been over to Angela's place, after getting into a bottle of vodka one of her older siblings had graciously purchased on their behalf, they'd made out for a bit and Gela had asked him, jokingly, if he'd been practicing or taking lessons. She had then laughed out loud at the expression on his face, which had simultaneously been trying to show pride, embarrassment, and paranoia. Just as Milo's mind was getting to the part where he worried that cuddling and kissing his older brother was a bit closer to something 'real' than perhaps he was comfortable with, his mind was brought right back to reality by the feeling of Eric's hand sliding under the waistband of his boxer shorts and groping his ass.
        "Eric...?"
He trailed off, unable to think of anything specific to say. For a moment, the random point popped into his head that he'd thought that making statements consisting entirely of the other person's name was something people only did in anime. Then, that hand brought his focus back for the second time in as many minutes, when Eric extended his forefinger and pressed it against that tight pucker beneath Milo's tail, pushing a short ways into his brother's body. Milo bit his lip and shivered, while Eric began nibbling at the side of his neck, where it merged with his shoulder, and murmured to his brother.
        "Mmmm, so you [i]aren't [/i]magic... not quite as tight as this afternoon, but damn if you haven't recovered nicely. This is gonna feel so good..."
As his older brother began gently thrusting his finger in and out of his backside, it dawned on Milo that Eric had gone into this assuming that he was going to bottom again. And, as his cheeks began to burn and his ears began to lower, he realized that inside, he was okay with that. He [i]wanted [/i]to just lie there and let Eric take him, since he knew the other shepherd would be gentle and tender and make it good for him. He [i]wanted [/i]to lift his tail for his big brother, to feel that sensation of exquisite fullness... but sometimes, there were more important things to a man than pure pleasure. He suddenly pushed back against Eric's close embrace, surprising the older shepherd, and took hold of his brother's wrist, pulling Eric's hand away from his back door. To his credit, the larger of the two canines looked rather worried.
        "What's wrong, Milo? Did I hurt you? Maybe I should have trimmed my nails first..."
Milo was able to keep his voice steady, stammer-free, but silently cursed himself as he felt himself blushing harder.
        "No, it's not that, it's just - you're getting all touchy-feely with my butt and talking about how [i]good [/i]I'm going to feel, and you didn't even [i]ask [/i]if I was cool with bottoming yet!"
Milo sniffed and looked away, crossing his arms over his chest. 
        "You may be older and bigger, Eric, but that doesn't make me your omega."
Eric slouched down, looking tremendously guilty. Even his ears gave an uncharacteristic twitch towards his skull.
        "...My [i]omega?[/i] Gonna play the cultural tradition card, eh?"
Wordlessly, Milo nodded. It was a rather canine-specific reference; in a traditional 'pack' relationship, there was a single leader of a group of wolves or dogs, called the Alpha, the biggest and strongest among those in the group, whose word was law as far as the others were concerned. But in the old ways, according to tradition, the smallest, weakest member of the pack was designated the Omega, who was just the opposite, required to do basically [i]anything [/i]asked of him by any other member of the pack, in exchange for their protection from the various dangers of the world. Although there were still those in this day and age who lived in packs, mostly in isolated communes, the tradition of selecting an omega was almost never practiced anymore, as it was seen by the civilized world as uncomfortably close to slavery. Eric reached over and put a hand on his brother's shoulder, looking genuinely uncomfortable.
        "Come on, Milo, I would [i]never [/i]do that to you! You're my only brother, man, I gotta look out for you."
He smiled thinly.
        "Look at it this way. If I thought of you as my omega, I wouldn't tolerate this kind of back-talk."
Milo looked back over at his brother, who mimed a backhanded smack, complete with vocally-provided sound effect, and then, doing a poor job of looking cross, Eric pointed at the tent in his boxers.
        "Get back to work, you slacker, or I'll revoke your masturbation privileges!"
Milo glared at his brother for a few more seconds before he relaxed, grinning again.
        "Just try and stop me!"

With the tension in the room lifted, Eric reached up and scratched the back of his neck.
        "Really, Milo, I'm sorry. Like I said at the gym, I'm not trying to take advantage of you, I just got used to it that way, I guess. So, uh, what [i]do [/i]you want to do, anyway? Flip a coin or something? I'd have to get my pants back..."
Walking forward on his knees, Milo put his hands on his brother's shoulders and began to push, gently lowering him to the mattress. 
        "I'll settle for being [i]asked[/i] where I want to be first... next time." 
He winked at the other dog and did his best to look predatory and dominant, though he suspected outsiders would just describe his face as 'cute', sadly. Eric actually managed to look surprised, but quickly recovered, grinning back in a somewhat self-conscious way. 
        "Well, I suppose I do owe you... it's just that you're, you know, better at it."
        "[i]Better? [/i]At - at being the bottom?"
He hadn't exactly been expecting that.
        "Sure, whenever I do it, it takes me forever to get comfortable, keeps hurting for a while, I always get so embarrassed about that. But you, you take it so easily these days, I'm actually kinda impressed." 
Milo wasn't sure how to take that, whether he should be embarrassed or proud. 
        "Well, if you bottomed as much as I did before your first time, maybe we wouldn't be having that problem." 
He thought about that for a moment and then blushed.
        "That didn't sound as gay in my head, somehow."
Eric laughed, though it was light-hearted, not mocking.
        "It's cool, I know it's hard to think sometimes when you're horny."
He looked thoughtful for a moment.
        "When [i]was [/i]the last time I was the bottom, anyway?"
        "That would be the last time Anne caught us and started calling the shots, remember? Thought the skinny guy doing the big strong guy was a 'nice contrast' or something."
Eric sighed, grinning and rolling his eyes.
        "Now I remember. Leave it to Anne to turn gay sex into art critique."
Frowning briefly, Milo muttered under his breath.
        "At least she wasn't asking you to [i]say [/i]stuff..."
        "What was that?"
        "Nothing, nothing, let's just get started. Where'd you leave the lube?"
        "Nightstand, bottom drawer. Next to the pelt mag, which you totally didn't see there."
Slipping onto the floor, Milo reached into the drawer and started searching its cluttered contents. As he moved the magazine, which was open to a two-page spread of a fennec vixen with bedroom eyes, out of the way, Milo felt weirdly put off that Eric was still resorting to the old fashioned kind of stress relief, as though Milo weren't enough for him. Running that thought through his mind again, the slender dog's eyes widened slightly and his blush increased a little bit before he forcefully put that thought out of his head and got back to the task at hand, retrieving the tube of K-Y and standing up, trying to act casual.
        "Heh, what pelt mag?"
Before he got back on the bed, he tugged down his boxers, leaving them on the floor, re-joining Eric in just his fur. He crawled up the bed and got in close again, nuzzling against his brother, enjoying the sensation of the other shepherd's warm fingers closing around his cock, which was only at half-mast. They didn't stay like this long, they only needed Milo to be fully hard before they began, so the brothers just kissed while Eric slowly stroked Milo's fattening penis. When the younger of the two was sufficiently stiff, he got up onto his knees as Eric tugged down his own underwear; the movement was rather quick, as Eric was a bit self-conscious about removing that particular piece of clothing - again, at least when he was bottoming. There was a hushed silence as Milo poured the gooey lube onto his fingers, before spreading it onto his rigid prick, shivering at the touch of the cold gel. He stroked himself a few times, to cover every centimetre of his erection, before wordlessly looking to Eric, who frowned. As his brother reached down to lift his testicles out of the way, Milo silently appreciated the idea that it was finally someone else's turn to blush. As he reached forward with his slicked-up fingers, Eric groaned, averting his gaze.
        "Man, I fuckin' [i]hate [/i]this part, makes me feel... I don't know..."
Before he could finish his thought, though, he grunted and stiffened for a moment, as Milo pushed his fingers against his big brother's anus, smearing the lube around for a brief moment before pushing inside a little, wanting it to be as easy as possible on both of them.
        "Jesus, and you're always talking about how tight [I]I [/I]am... alright, you ready for this?"
        "I guess so. I'll, uh, I'll let you know when it hurts, okay? The usual deal."
Reading past his brother's words and looking at the nervous twitch of his tail to his side, Milo shook his head, smirking.
        "Man, you [i]are [/i]nervous! You gotta relax, dude, it makes it easier. Literally."
It was hard to tell if he was more relaxed, but he certainly seemed more self-conscious for a moment.
        "Fine, fine, whatever you say, Dr. Buttlove, you would be the expert."
Eric took a deep breath and closed his eyes, and this time, he did seem to relax a bit, releasing the tension in his muscles.
        "O-okay, let's do this."
        "Alright, let me just..."
Milo manoeuvred closer to his brother, lifting and spreading Eric's legs, settling in between them and lowering himself down as he put his hands under Eric's butt and lifted, getting them both in the right position. Eric let out a sharp breath as he felt a rigid prick poking against his rear entrance, and visibly braced himself.
        "Okay, here we go."

As Milo pushed his hips forward, increasing the pressure on his brother's tight backside, Eric actually shivered and let out a whimper. The stubborn muscle resisted valiantly, but Milo was rather determined, and soon enough, he emerged victorious, pushing past the obstruction with a little bit of force, and sliding into his brother's slicked-up passage, managing to hilt himself fully in Eric's tight warmth in a single thrust. As his groin bumped against the other shepherd's buttocks, Milo saw Eric's entire body tense up, felt him clench down on his erection, [i]hard[/i], though he didn't make a sound. 
        "You okay, Eric?"
It took a second for the older dog to respond.
        "...Oh, f-[i]fuck[/i]... Goddamn, I forgot how - how uncomfortable that is..."
This time, his ears managed to go halfway down and stay there as he looked up at his brother, clearly embarrassed to be making such a request.
        "C-could you stay right there for a bit... please? I - it kinda hurts..."
Milo grinned and adjusted himself for comfort, leaning down and bracing his arms against the bed, careful not to let the movement transfer to their joining. This let him put his weight on the mattress so he could lean forward and thrust with his hips... but it also put him firmly inside his brother's personal space, where he could nuzzle against Eric's cheek reassuringly as he answered.
        "Of course, after all those times you waited for me to be ready, how could I not?" 
When he got a smile out of his brother, Milo winked.
        "Now, stop acting all embarrassed and stuff before you give me an identity crisis!" 
The Thompson brothers laughed quietly together for a bit, and then began to kiss. As their dark-furred muzzles met, Milo reached down and took hold of his brother's cock, which had wilted to half-mast with his discomfort during penetration. While the two of them kissed slowly, tenderly, he began to gently knead and rub Eric's penis with one hand, encouraging it to stiffen and grow again. After a few moments, Eric broke off the kiss and whispered a simple 'alright', and Milo carefully pulled back with just his hips, until just the head of his dick was still inside, and then thrust forward again. Although Eric winced once as he did so, the older dog made a dismissive gesture, encouraging Milo to continue, so he kept the movement going, building up the rhythm as he thrust into his brother's tight rear again and again. They had to stop a few times because it was just too much for the elder canine, but as they continued, it because easier, smoother, and Eric let out a sigh as he lay back, the tension leaving his muscles as he finally got used to it. Milo smiled.
        "We good?"
Eric didn't quite chuckle, but he did manage a smile.
        "Y-yeah, little brother. We good."
With that, Milo allowed himself to focus more on the sensations of his brother's tight passage squeezing along his length, of the scent of the other dog's arousal, of the way he could feel Eric's pulse through his erection, which had begun to drool precome onto Milo's gently stroking fingers. As Milo let out a quiet moan, Eric pulled him in close for another kiss, and the younger shepherd began to thrust with a little more strength, stroke his brother's cock a little bit faster. When they broke off and came up for air, they just looked into each other's eyes for a moment, then simultaneously blushed and looked away. As Milo studied the pattern on Eric's pillowcase, he heard his brother whispering to him.
        "...I think I can see why you like this, bro."
Shuddering, Milo picked up the pace just a little bit more, thrusting into his brother's backside and rubbing his cock just the way Eric had taught him, careful not to squeeze too tightly or stroke too fast. 

It was like this that the brothers continued for a while, kissing and nuzzling each other, Eric's hands wandering Milo's body as the skinny teen continued rutting into the older dog's body. Milo's tail was wagging energetically behind him as he kept thrusting, which was a nice change of pace from keeping it flagged high in the air. As he kept the motion going, he felt the other shepherd's hands sliding down to his butt, squeezing his cheeks and pulling when the younger dog thrust forward, adding a little more force. This surprised Milo, but Eric didn't seem to be in pain, grunting each time Milo slid home into that tight, welcoming embrace, so he just went with it. That behaviour didn't last long, though, and soon Eric went back to just lying back and taking it. As they broke off the kiss, and Eric began to nuzzle and nip lightly at the skin where his brother's neck met his shoulder, Milo groaned, feeling himself throb within Eric's tight channel.
        "God, Eric... this is so good... so [i]tight[/i]..."
With a somewhat strained chuckle, Eric grinned thinly.
        "Enjoy it while you can, little brother... It's only a matter of time - [i]ah, fuck[/i] - before you and Gela admit you're fuckin' crazy about each other... and I bet she'd [i]never [/i]let you under her tail." 
Blushing and frowning, Milo lifted an arm and gestured towards their joining.
        "Can we keep the conversation on [i]your [/i]tail while we're doing this?"
Eric managed to give his brother a sly grin.
        "Heh heh... Sorry, I'll try... not to talk about your girlfriend that way."
        "You know, you [i]are [/i]talking to the guy whose dick is in your ass. That could go [i]real [/i]bad for you, real quick."
His next thrust had [i]just [/i]a bit more force behind it than usual, leading Eric to inhale sharply and tense up, his rear clenching down on Milo's erection for a moment. He now looked a little bit worried, and his next apology sounded rather more honest.
        "...Sorry, Milo."
As he continued at his previous pace, Milo grinned benevolently at the canine beneath him. 
        "Apology accepted, big brother."

After that, the Thompsons somewhat lost track of time, kissing and touching and licking and groaning as they coupled vigorously. Milo shivered as he took in the scent of sweat and canine arousal, beginning to speed up his tender ministrations to Eric's penis, which by now was drooling a fairly constant stream of pre onto his brother's fuzzy abs. He could feel himself throbbing from time to time, as Eric continued clenching down on him at random, and could feel the beginning of the end, his arousal beginning to build within him. After a while, though, he stopped thrusting altogether, releasing the older dog's cock as he began to pant. Eric broke off the kiss to look up at his brother in confusion.
        "Why you stopping, Milo? You getting close?"
With a self-conscious grin, the other shepherd shrugged.
        "I'm just, uh... my hips are kinda tired. I guess I need more practice being the top."
With a gentle laugh, Eric reached up and scratched his brother between the ears, helping Milo feel much better.
        "That's okay. I had the same problem the first handful of times I was with a girl, and that's with stamina training for soccer! It's just something you need to get used to, you know?"
He raised an eyebrow after a moment, looking curious.
        "Funny, though, I would have figured between me and Gela, you'd be better at that by now."
Blushing, Milo averted his gaze, suddenly feeling the sting of shame.
        "Uhhh... me and Gela don't do it all that often, Eric. And..."
He swallowed.
        "She always wants to do it cowgirl-style, so she's the one doing all the work."
There was a moment of silence, and then, to his surprise, instead of mockery, even gentle ribbing, Eric just nodded thoughtfully.
        "That sounds about right for Angela Taylor, now that I think about it. Now I feel kinda bad for topping all the time, didn't realize."
Milo had expected to feel embarrassed by whatever Eric's reaction was; now he felt slightly self-conscious for being surprised by his brother's neutrally sympathetic reply. Looking back into Eric's eyes and hoping he wasn't blushing even harder, he shrugged again.
        "N-no, it's fine, it's not like I don't, uh, [i]enjoy [/i]myself, I just don't get a lot of humping practice." 
Eric snickered, of all reactions, clearly amused.
        "I like that. Humping practice. Hey Thompson, get your head back in the game and your dick back to pumping that ass!"
Laughing softly, Milo grinned and pushed himself back up, the fatigue having mostly left his muscles.
        "You got it, coach!" 

As he began to thrust once more, taking hold of Eric's prick, both brothers let out pleasured sighs, and once they'd gotten back up to speed, Milo leaned in to capture his lover's muzzle with his own. It wasn't long, though, before Milo broke it off with a whimper, starting to slow down. 
        "Dammit... I'm getting close, but I don't want to come yet..."
Eric reached up and wrapped his arms around Milo's shoulders, looking up at him with a grin. 
        "It's - it's fine, little brother. I - you should keep going, don't hold back."
        "But I -"
Eric leaned up and nuzzled against his brother's cheek, whispering into his ear.
        "No, really, it's okay, you can finish me off afterwards."
With a grin, Milo nodded and began to speed up, quickly reaching his former pace as he began to pant and shudder.

Before long at all, Milo was unable to hold back the whimpers, feeling the big moment rapidly rushing towards him, and he bit his lip and arched down low over his brother's chest in anticipation. Speeding up his thrusts a bit more, though he couldn't go full-tilt without hurting his relatively inexperienced brother, he looked down at Eric and smiled thinly.
        "H-hey Eric? You remember - [i]nngh[/i] - after the shower, when K-Keith caught us?"
Eric raised an eyebrow. This was a very odd time for Milo to be making conversation. Normally by this point he just let the whimpers and moans speak for themselves.
        "Yeah, of course... I told you - [i]ooh, [/i]not so rough... I told you, he's cool, not gonna tell anyone."
        "No, I - I believe you... But d-do you remember how you smacked my - my ass? To show him that you were the one who f-fucked me?"
The elder canine's face showed his confusion very clearly; Eric had no idea what was going on here.
        "Uhhh... yeah?"
        "W-well, I didn't appreciate that... [i]oh Christ, so close... [/i]sorry, I didn't appreciate that sh-show of dominance."
        "Umm -"
        "But it's okay! D-do you know why?"
        "No, why?"
Suddenly Milo's smile went from 'thin' to 'from ear to ear', and it was a rather toothy, predatory grin at that. Before Eric could react, Milo did something even [i]more [/i]unexpected, and pulled out of his brother's rear completely. Rearing back, up onto his knees, Milo leaned forward and grabbed his rigid, slicked-up penis, and began stroking it with all his energy. 
        "Oh, ohhhh fuck... [i]ohhhhhhh![/i]" 
Hunching forward, Milo let that syllable trail off into a long moan of release as he was overwhelmed by his orgasm, having timed it perfectly. Eric was still trying to react to the situation when his brother's erection began to throb, spurting hot, wet bursts of canine seed into the cool air of the room, where they fell down upon his hapless sibling's body. Milo was rather productive, and came rather forcefully, painting Eric's stomach and chest with his sperm, his fist a blur on his throbbing shaft as he grunted and twitched, Eric too shocked to do anything but lie there as warm semen rained down upon his prone form, most of it decorating his torso, though a single shot made it as far as his throat.

When Milo's climax had finally run its course, his own act of dominance complete, he sagged backwards, sitting on his lower legs with a satisfied groan, tongue lolling out of the big, stupid grin on his face. While he sat there, cock still in hand, panting like a feral, his tail wagging as fast as physically possible, Eric just lay there, stunned, feeling the warmth of his brother's release on his chest, the strong scent of canine semen in the air, and the fact that his own penis was still achingly stiff. Gingerly lifting his head to survey the damage, he was weirdly impressed that his brother could come so much after they'd just had sex that afternoon. 
        "Jeez, look at it all... Milo, what in the hell was that about?"
Looking down at him, Milo feigned ignorance rather transparently.
        "What do you mean, big brother? I was just showing off that I was the top, is all. You know, sort of a 'Aww yeah, I tapped that' kind of thing."
As he smirked, Eric shook his head. The point was kind of hard to miss.
        "Hurt your feelings, huh?"
Milo nodded, and Eric reached up to scratch the back of his head.
        "Sorry. I guess I just got carried away, it was kind of a rush realizing we were going to get away scot-free. I just didn't think about how [i]you'd [/i]feel about the ass smack. I'm sorry, I would never do that to a girl, so I never should have done it to you."
Eric winked up at his brother.
        "Though for what it's worth... you really [i]do [/i]have a nice, spankable ass. So firm, so round... so hard to resist..."
Milo laughed as Eric leaned forward, reaching around towards his little brother's rear with an enthralled expression on his face. Pushing his hands away, Milo smiled genuinely.
        "Thanks, Eric. I think."
Looking back down at the glistening seed on his chest, Eric shrugged.
        "Well, I [i]was [/i]going to ask you to catch my stuff when I came... and, uh, probably try to talk you into licking it up... but since I'm gonna need a shower now anyway, you might as well just let loose."
There came a sudden scuffling noise outside the door, and both brothers turned to look, frowning. The door was [i]definitely [/i]locked, they'd learned enough to make sure, but there was no knock, no rustle of the handle, nothing further except silence. Shaking off the momentary distraction, Milo looked down at Eric's poor, neglected prick, still hard as iron, and grinned. 
        "Well, I don't want there to be any hard feelings... so let me make that up to you."
The slender shepherd slid down to lie on his stomach, raising his legs at the knees to make room for the footboard of Eric's bed, and placed his hands on his brother's thighs, intentions obvious. As Milo leaned in towards Eric's cock, the elder brother chuckled appreciatively. 
        "Ohhh yeah, I've definitely got a 'hard feeling' you can help me out with."
Milo paused and lifted his head, cringing at the terribleness of that line and giving his brother a dirty look. Eric laughed once and rubbed the back of his neck again.
        "Yeah, sorry about that."

Shaking his head with a smirk, Milo turned back to his task, taking hold of the base of Eric's erection, and leaned in to run his tongue along the sensitive underside of his shaft. Enjoying the quiet moan the action earned, he opened his lips and began to slide down his brother's prick, gently sucking as he teased along the taut skin with his tongue. Eric's hands curled into fists, bunching up the sheets, as he began to squirm under his brother's gentle ministrations, twitching and writhing, not sure what to do with all his energy as Milo did all the work. For his part, the younger sibling seemed oblivious to this, focusing on pleasuring his brother, bobbing his lips along Eric's shaft in deep, even strokes, the depth of his canine muzzle allowing him to easily take his brother in to the root. After a few moments, Eric found himself struck with a thought, wondering if this was how Milo usually felt, as [i]he [/i]was normally the one who finished an energized Milo off after topping him. It wasn't an uncomfortable feeling per se, just... the more worked up he got, the more invigorated he felt, his muscles twitching as he restrained himself; to his embarrassment, his right leg wanted to kick out and retract again and again, like a feral being scratched between the ears. Letting go of the bed, he reached up and covered his face as he let out a deep groan, before spreading his hands enough to uncover his muzzle so he could speak.
        "Ohhh God, Milo... fuck, just like that, that's so good..."
Moaning again, he pushed up towards his brother's face as he felt Milo take hold of his scrotum, gently squeezing and massaging his testicles. He let go of his face as he felt Milo release his cock entirely, but before he could protest, the slender dog took hold of his penis and began to stroke, grinning. 
        "You know, Eric... I didn't miss that bit about wanting to talk me into licking up your come. And here I had just made a big point about you trying to embarrass me..."
As he spoke, the movements of his hand began to slow down.
        "Aww, come on, Milo, don't I at least get points for honesty?"
Milo let go of the other dog's balls to reach up and place a single finger on his chin as if thinking it over, not even trying to hide the smirk on his face as his strokes slowed to a crawl.
        "Hmmm..."
Eric let his ears lower and stuck out his lower lip, turning on the world-renowned Puppy Dog Eyes at full blast, but alas, as a fellow canine, Milo was immune. Letting out a whimper, he fought the urge to reach out and actually take hold of his brother's hand.
        "Miiiiloooo, you're gonna give me blue balls! Please? I - I need it so bad..."
Letting out a theatrical sigh, Milo shrugged.
        "Well, okay. Honesty gets you one point."
He sped his strokes up a bit, and Eric throbbed in his hands. Milo winked and continued.
        "Admitting that you need it like that, that gets you another one."
He sped up his stroking to full speed, and Eric leaned back with a grateful groan.
        "But you [i]did [/i]let me top you again, and you did apologize for the ass smack... with the proper motivation... so [i]that [/i]gets you..."
Eric cried out in surprise as his brother bent down and took his prick back into his mouth. 
        "Oh Jesus! ...Th-thanks, Milo... ohhhhh..." 
Lying back with a big, stupid grin on his face, Eric shivered at the feeling of his brother's tongue running across the skin of his aching penis, teasing at the sensitive zone where the head met the shaft. He couldn't help but grunt and gasp as he resumed twitching under Milo's skilled work, and only a few minutes later he shuddered and let out a moan.
        "Oh God, I'm getting close, don't stop..."
Milo didn't respond, obviously, but the corners of his mouth turned up as he increased the pace, returning a hand to Eric's testicles, giving them a firm squeeze, feeling the sac beginning to tighten up as the bigger shepherd approached orgasm. Eric's breathing became heavier, somewhat ragged, and his writhing became more and more pronounced as he murmured 'oh God' to himself over and over. Finally, he clapped his hands over his muzzle to contain an almighty moan of pleasure as he arched his back and stiffened, every muscle trembling as he climaxed, his cock throbbing in Milo's mouth, each pulse of pleasure spilling his seed onto his brother's tongue, which even now continued to tease along the twitching organ. Meanwhile, Milo's hand continued to squeeze and knead his brother's balls, while he'd moved his free hand just behind them, pressing against the skin just behind Eric's scrotum in time with the rhythmic spasms of his penis; Anne had taught him that a certain level of prostate stimulation was possible from massaging that spot, though of course not as much as was possible [i]inside[/i]. As Eric continued to muffle his cries, Milo worked feverishly, coaxing as much pleasure as possible out of his brother before his orgasm faded out.

When Eric slumped down against the mattress with a groan, Milo sat up, feeling rather pleased with himself. After a moment's thought, and checking to make sure Eric was still dazed, the blushing shepherd swallowed his mouthful, seeing no convenient place to spit it out. He figured that his pride could take the minor hit, after all the teasing he'd done to Eric, who by now was actually laughing softly.
        "Damn, [i]thanks[/i], Milo, that was a nice one. Are you [i]sure [/i]you haven't been practicing? Maybe going down on Anne or Gela with a strap-on? Seems like your kinda thing."
Milo found he couldn't help but laugh himself, shaking his head as he leaned forward and lightly punched the other dog in the arm.
        "You never learn, do you?"
Eric looked up and winked, not looking the slightest bit put off by the punch, though he rubbed his arm as he laughed.
        "Absolutely not. That's what brothers are for, isn't it?"
For a brief moment Milo regretted not spitting out Eric's seed directly onto his fur, but he felt too pleased to hold much real resentment, and just laughed with his brother. After a few moments, when they'd calmed down again, Eric looked down his body and sighed.
        "Yeah, I'm gonna need a shower. It's a good thing mom and dad aren't home." 
Looking down at himself, Milo realized he was rather sweaty from their energetic coupling. He sat there quietly as Eric got up off the bed and retrieved a towel from his dresser, weighing something in his mind.
        "...Hey, Eric? Can I, uh, join you in that shower? I could use a wash myself."
Eric grinned widely, chuckling.
        "Wow, you're insatiable. You really think you're up to it?"
Smiling shyly, Milo nodded. Eric laughed softly and tossed Milo his spare towel.
        "Well then! Let's get over there and get ourselves nice and clean."
Wrapping the towels around their waists for the bare minimum of decency, in case their parents walked in the front door during the vulnerable moment when they were crossing the house, the brothers quickly made the dash from Eric's basement bedroom to the second floor, where the bathtub and shower were found. They slowed down, feeling more confident, as they approached the bathtub, and Milo turned to Eric, smirking and managing not to blush.
        "You know... maybe I should start making a workout a regular part of my schedule. I could stand to be a bit more toned, after all, don't you think?"
Grinning back at the younger shepherd, Eric nodded as he reached out to the doorknob.
        "Certainly couldn't hurt!"
There had been a little more Milo had been planning to say in this thinly-veiled manner, but the thoughts evaporated on his tongue as Eric swung the door to the bathroom open...

...And they were greeted by the sight of their sister Anne, sitting up on the counter next to the sink, one silky-furred leg languidly crossed over the other. She smiled as she saw them, the look on her face making it absolutely clear that she had been expecting them. Though it didn't really take a rocket scientist to work certain things out, given that she was wearing her fuzzy lavender bathrobe, and, apparently, absolutely nothing else. Both brothers stared blankly, and for once it was Eric who found himself blushing as he realized his chest was still blatantly covered in semen. Milo spoke up first, though he was hardly eloquent.
        "...A-Annie? What...?"
Giggling, sounding absolutely delighted with herself, Anne gestured to invite them into the bathroom.
        "Hey boys! I just happened to be walking by the basement when I [i]couldn't help but overhear [/i]what sounded like, ah, a very satisfying work out session."
Remembering the scuffling sound at the door, Milo began to blush too, realizing how much of their tryst had been overheard.
        "I figured you two would need a good washing afterwards, and I was wondering..."
Hopping off the counter as Eric finally stepped inside, she ushered Eric and Milo into the bathroom and closed and locked the door behind them. Then, turning to face the males, she opened her bathrobe, confirming Milo's suspicions, and dropped it onto the floor, standing there boldly, smiling confidently as her brothers couldn't help but stare at her unclothed form. Placing her hands on her hips, she cocked her head in the direction of the bathtub.
        "I know it's not the biggest tub in the world, but what do you think, boys? Room for one more?"
Eric and Milo silently exchanged a glance, smiles beginning to form on their faces, and as they turned back to their sister, Eric chuckled lightly and shook his head.
        "You know, I remember when the shower was used to actually get [i]clean[/i]..."
Then there was much excited laughter as water began to flow, steam began to rise, and hands began to explore. As Milo stepped into the tub with his siblings, tugging the curtain in place to seal them in together, he couldn't help but make up his mind; he was [i]definitely [/i]going to have to go to the gym more often.
