[center][u]Anne and Milo: A Teaching Experience[/u]
By Green[/center]


Anne Thompson sat on the couch, sending texts at a blistering pace to her various friends, about all the normal things a girl in her late teens concerns herself with. The German shepherd wasn't quite up to tail-wagging status yet, but she was feeling pretty content as she sat there exchanging e-gossip with her pals. So she wasn't terribly pleased when Eric and Milo, her older and younger brothers, respectively, stormed down the stairs, clearly not pleased with each other. Eric was speaking as they reached the main floor.
        "Jesus, dude, what's gotten into you today?"
Milo turned around and gave him a very dirty look, but didn't say anything.
        "Dammit, Milo, I didn't mean it like [i]that[/i]..."
        "No, it's fine, I know exactly how you meant it. And you know what, Eric? I've got a much better idea for how to spend the afternoon. Why don't you go fuck [i]yourself?[/i]" 
As he stormed outside, Eric caught the door mid-slam, and then yelled after his brother.
        "Fine! Go run to your fucking girlfriend, maybe Angela will let you have your [i]balls[/i] back!"
Milo yelled something back, indistinct from where Anne was sitting, but obviously very angry. Eric made a rude gesture out the door and slammed it behind him, muttering under his breath. Anne suspected this wasn't anything major, just the kind of argument that brothers get into all the time, but all the same, it had her quietly worried, distracted enough to lower her phone and stop checking it, actually ignoring the buzz as yet another text came in.
        [i]Sounds like they're really pissed at each other. Man, I hope neither of them does something stupid, they might stop doing The Deed.[/i]
The more she thought about that, the more she frowned. 
        [i]God, nothing gets me as hot as watching those two, they can't stop! Not to mention that if they stop screwing around, they'll [/i]never [i]fall for each other for reals, and that'll be a huge bummer.

[/i]As she watched her older brother return, still fuming, from the kitchen, Anne decided to do her best to keep the dream alive. As Eric passed by the entryway to the room, Anne called out to her brother, giving him a target to bitch at.
        "Trouble in paradise?"
        "Ha, ha, that's [i]hilarious[/i]."
Instead of further antagonizing him, as much fun as it would be, Anne lowered her glasses and looked at him, trying to look more neutral now that she had his attention.
        "Seriously, Eric, what happened?"
The irritation still burned in his eyes, but now Eric looked oddly uncomfortable, like he'd been put on the spot, avoiding eye contact.
        "Well, I, uh, I was feeling a bit pent-up, so I went and, you know, asked Milo if he wanted to fool around." 
        "And?"
        "[i]And[/i] he fuckin' [i]blew up[/i], acted all offended that I '[i]assumed [/i]he would want to mess around'. I dunno what pissed him off so bad, it's not like I [i]demanded[/i] he drop what he was doing and suck me off or something. [i]Fuck[/i]..."
Anne mentally added that scenario to her "To-Fantasize-About" list, but didn't pursue it just yet, just nodding empathetically.
        "I swear to God, it was just like I'd done it all those times before, the same way [i]he [/i]does it when he's in the mood. It's gotta be something else."
There were a few seconds as Anne tried to think of the softest way to ask her question, before deciding to be direct.
        "Eric, did something... [i]happen[/i] the last time you two forgot to invite me to the show?"
        "Man, I don't know, maybe?"
        "What do you mean, [i]maybe?[/i]"
He ran his hands through his hair, clearly still uncomfortable discussing this with his sister.
        "I mean I'm not sure, what do you think I mean! ...Look, it was mostly like it's been a bunch of other times, we did it doggystyle -"
Anne snickered, but Eric allowed that one.
        "- and I was on top. The whole thing went okay, I thought, it was actually one of our better, uh, sessions, Milo seemed a bit more, I don't know, 'into it' than he normally did, seemed more relaxed, but there was this thing at the end."
Sensing he was going to finish that thought, Anne remained silent as he paced to the window, looking out at the empty street.

        "When I went to get Milo back after I, you know, came, I saw that he'd finished already, blew his load all over the sheets. But the thing is, the position we were in, I had my hands on top of his the whole time, so he couldn't have just been jacking off while I was fuckin' him. Th-the only thing I could think of was that he'd lost it from having his dick rubbing against the bed, and he confirmed that, so I guess that's what happened, but it was still kinda weird, eh? Today was the first time I'd asked him since then." 
Another possibility immediately jumped into Anne's mind as Eric told the story, and as she watched him carefully, it seemed to her that either Eric didn't know about this possibility, or he was actively trying[i] not [/i]to think about it. Either way, he definitely seemed to [i]want [/i]to believe Milo's explanation and leave it at that, though even in his denial he seemed to recognize that something wasn't quite right. Now that her brother had both quieted and calmed down, she stood up and went to him, putting a hand on his shoulder reassuringly. 
        "He'll be fine, Eric, he's seventeen, guys sometimes freak out for no reason at his age. Look, I'll talk to him when he comes home, and hopefully by the end of the week, you two can kiss and make out."
He glanced over his shoulder and gave her a Look, but he couldn't hide the smirk on his face.
        "[i]Up![/i] I meant kiss and make [i]up![/i]" 
That finally brought a small chuckle out of her older brother, who put a hand on top of her head and jostled her hair like she was a small child.
        "Sure you did, sis, [i]sure[/i] you did." 
At that moment, the phone in her hand made a light tone, which caught her attention. Anne had set up all her friends with personalized text tones, so that whenever she received a message from a friend or family member, her phone emitted a second or two of a song that reminded her of them. For it to make the default noise meant she was receiving a message from someone outside of her social circle, which made her immediately curious. She failed to notice Eric pulling his own buzzing phone out of his side pocket as she slid hers open and clicked the update button. The message quickly flashed up on screen; it was from Angela Taylor, the female mouse that Milo had just gone to visit, his best friend since the two of them had been in pre-school together. The message read 'What's up Milo's butt? He's really pissed 2day, wtf', and it caused both siblings to snicker at Gela's unintentional joke. Anne gave her brother a big grin and winked.
        "Well... should we tell her?"
Eric laughed, seeming much more at ease now, and shook his head.
        "Hey, man, I told you, I didn't get there today!"
Anne laughed with him, and the tension of the situation was completely gone.

[center]***[/center]

Later that night, after returning home and speaking very little to his family, Milo slept fitfully, whimpering quietly as he twitched and moved in his sleep. 
        "No..."
Given his unconsciousness, there was almost no force behind his voice, barely above a whisper. He suddenly thrashed to the side, moaning. 
        "No, don't look... No, please..."
The shepherd's movements became stronger, faster, as he thrashed on the bed, until finally, with a cry of '[i]Stop![/i]', Milo burst from the bed, sending the blankets to the floor with a muted [i]whumph[/i], charging to the door, blind fear in his eyes. He struggled with the door lock for a second and then rushed outside - only to nearly fall down the stairs opposite his room, stairs he apparently hadn't been expecting to see there. He pinwheeled his arms as he forced himself to stop, falling unceremoniously backwards onto his butt instead. He was still light-headed, not quite awake all the way, and his heart rate hadn't calmed down yet. That was about the second or third dream this week. Rushing out into the hallway in a panic was new, though. He'd woken up so suddenly he hadn't yet realized that it was a dream, and more importantly, that it wasn't happening any longer, he'd just suddenly felt that he was free and tried to run. Just as he was wondering how he could be any more embarrassed, a voice cut through the silence.
        "...Milo? Are you okay?"
He looked up, momentarily startled back to that fearful feeling, then relaxed even as he blushed, seeing that it was his sister Anne, probably on her way to or from the bathroom, wearing pyjama pants and a long T-shirt emblazoned with the faded logo of a pop band that had broken up years ago. She had her hair up, and was squinting slightly, having left her glasses behind. He looked down at the carpet, trying to act natural, as if bursting out of his room and hanging out on the floor was something he did all the time. 
        "Annie? Well, I uh, I... I had a bad dream, is all... it's nothing..."
Thinking about the details of the dream made him blush even harder, he was glad his sister couldn't see what he was thinking.
        "Oh. Do you... wanna come and talk about it?"
He frowned slightly, not sure he was hearing her right.
        "What do you mean?"
Anne shrugged and gestured towards her bedroom.
        "You know, the way you used to come over when you had a bad dream."
He opened his mouth to turn her down, embarrassed, but then he remembered. When he'd been small, he'd always relied on his big sister to help calm him down and reassure him after he had a scary dream. This was a rather significantly different kind of dream, but... 
        "Does it have to do with why you were angry at Eric this morning?"
He started at that. Maybe she [i]could [/i]read his mind.
        "Wh-what?" 
She shrugged, and walked over to him, helping him up. 
        "It doesn't take a rocket surgeon to figure out there's something bothering you, Milo. You wanna come and talk about it? It'll probably make you feel better."
That was a reference to a very old joke in the household, based on the way their father used to playfully refer to easy tasks as 'not exactly rocket surgery'.
        "Well..."
        "I promise I won't repeat what you say to anyone else, if it helps."
It did, actually.
        "Well I guess I could give it a try..."
Smiling, Anne put her arm around his shoulder.
        "Then come on, little brother."
He grinned back, if weakly, but was confused when Anne stopped and gently nudged him in the direction of her room.
        "What are you waiting for?"
Now it was Anne's turn to blush, looking slightly put-off by the question.
        "Jeez, Milo, I just still need to pee, you just go ahead and wait for me in my room." 

And so it was that Milo found himself sitting on his sister's bed, waiting for her to return from freshening herself up, and wondering if her room had always smelled this nice. He felt oddly nervous, which he supposed was counter-intuitive. As he heard the toilet flush, knowing it would still be a few minutes, as Anne always took her time washing up after being in the bathroom (something that he and Eric had found infuriating as children, waiting to get inside), Milo suddenly felt the impulse to flee, to hurry back to his room and pretend the whole thing had never happened. All in all, he'd [i]really [/i]rather not discuss this with anyone. And yet he stayed, sitting right where he was. Maybe he was just too tired to run, but maybe he had finally reached the point where he needed to share his fears with another person. Then again, maybe he was just afraid of falling down the stairs again. He didn't quite feel comfortable getting under the covers and lying down, so he just sat there, kicking his feet and humming elevator music to himself, which seemed entirely appropriate. He glanced to his side; Anne's glasses lay inside their case on her nightstand, next to her alarm clock, her reading light, and a book, apparently her idea of night reading. '[i]The Midnight Lesson[/i]', it was called, with a pair of muscular men, an orange fox and a white wolf, standing shirtless next to a window before a starry sky and a full moon. Milo hadn't even been aware that gay romance novels were a thing that actually existed. 
        [i]I guess she must order them from the same site as all those yaoi comics she's always fawning over.
[/i]Finally, the sink shut off, and Anne left the bathroom, turning off the light behind her, and then returned to her room. It was dim, but the small reading lamp on her bedside table was on, so there was light enough for the siblings to see. Anne smiled benevolently at her brother as she closed and locked the door, and he was instantly reminded of why he'd found her so comforting all those years ago. 
        "Scootch over, Milo."
He silently did as she asked, and she lay down on the bed, patting her stomach with a grin.
        "Make yourself comfy, little brother."
He frowned slightly.
        "I thought this was just gonna be talking..."
She giggled softly.
        "I meant use me as a [i]pillow[/i], you deviant, what did you [i]think [/i]I meant?"
Her wink was mostly unnecessary; the two of them had recently shared a whole lot more than a bed, so he figured she was being facetious when she mocked him for such thoughts. As he lay down between her legs, blushing, resting his head on her surprisingly soft stomach, he wondered how he'd gotten into this.
        "For the record, Milo, you know I'm not particularly subtle about things like this. If I was suggesting that you make use of my uterus, you'd know about it." 
She began to run her hands through her brother's hair, scratching behind his ears gently, soothingly, as she put on her best therapist voice.
        "So, little brother, tell me about this dream of yours."
He let out a quiet whine, clearly uncomfortable.
        "Well... before I tell you, you have to promise..."
        "What is it, that I won't tell anyone? I thought I already promised that."
        "No, it's, uh... y-you always talk about this kinda stuff as being 'super hot', and I don't want to hear how, you know, [i]sexy[/i] this dream was, it really bothered me."
Anne waited only long enough for her mouth to suddenly go dry before responding,
        "Of course, I wouldn't want to make you uncomfortable."
For a moment, she paid particular attention to his ears, scratching and massaging at the thin flesh, helping Milo relax.
        "W-well... okay."
He cleared his throat, probably just to buy another couple of seconds before he actually had to start talking about it.

        "So it started with me having lunch at school, you know, in the caf. And, uh, I'm sitting there at the table, and everything is swell, when suddenly Eric is just [i]there[/i], and he, um, he..."
Milo swallowed, fighting the urge to lower his ears.
        "...He picks me up, puts me on the table, and, um, pulls down my pants. And then he, well you know... right there in front of the whole room. So he keeps doing me, and people are all around, watching and, and [i]talking[/i]. Talking about how I'm, um, a 'butt-slut', or how 'well I'm taking it', or other stuff like that. And I even see Gela, and sh-she just looks at me like she never wants to see me again, all angry and hurt, and then runs off. B-but I don't care about any of that because, um..."
He whimpered quietly before continuing. Anne suspected that 'the good part' was about to begin, and that it would be relevant to the problem at hand, too.
        "I didn't care b-because getting fucked felt really, [i]really [/i]good, getting me crazy hot. And it wasn't just that... it was that I was getting fucked by [i]Eric [/i]that turned me on so much. I - in the dream, I actually c-came just from being fucked, without even touching my, uh, my cock. And I didn't care! I didn't care that all those people were seeing me bust a nut from getting railed by my brother, just because it felt too good! God, Annie, I was... I was Eric's [i]bitch![/i]"
He let out another whimper, and shivered against his sister, his cheeks burning, almost afraid of how she would react. But she didn't make fun of him the way the other students did in the dream. She bent forward for a moment and wrapped her arms around him, hugging him tight.
        "Oh, Milo..."
Although he felt a little better in his sister's embrace, he wasn't terribly thrilled with the impression he got that she'd been expecting something like that, and now his ears finally gave in and flattened themselves against his skull.
        "Let me guess, Milo. This isn't the first time you've had a dream like that."
        "N-no..."
Milo dreaded the idea of having to go through the set-up of all those dreams before they got to the same ending, but, to her credit, Anne never asked. That only bought a short moment of relief, however, as what she did ask managed to somehow be even more dreadful.
        "Well, most people have bad dreams because their subconscious is trying to work out something that's bothering them in the real world. Which begs the question... what's bothering you?" 
Milo looked back over his shoulder at her and swallowed yet another whimper.
        "A-are you sure about that? You know, you're not a, a psych expert or anything..."
She shrugged, giving him a sly smile.
        "[i]Well[/i], my other source is yaoi manga, and [i]that[/i] would suggest that you're just madly in love with Eric and want to be his Uke. Which interpretation do you prefer?"
        "Well,[i] [/i]Jesus, Annie, when you put it [i]that[/i] way..." 

He cleared his throat again, and then forced himself to utter every syllable, wondering if one could literally die of embarrassment. 
        "The - the thing that happened at the end of the dream... that's actually happened a couple of times now. The f-first time Eric and I did it, when I was the bottom... I - I tried to fight it, tried to hold it in, resist, but..."
He began to shiver against his sister, but didn't notice, so focused was he on his memories.
        "I - getting f-fucked felt so goddamn good, I'd never felt anything like that, and I came without touching myself even once. I didn't know that could even [i]happen![/i] I told Eric that I got too horny and had to whack off, and he bought it, but I couldn't stop worrying about it, about what it meant."
Now that he had started, Milo kept going and going, letting it all out. Anne just lay there, continuing to run her fingers through his hair.
        "I told myself that maybe that happens to all guys the first time they bottom, but I've [i]never[/i] been able to make Eric come by fucking him, no matter how hard I do it! I - do you remember the first time you made us let you watch?"
        "Mmm-hmm."
Of course she did, she doubted she would ever forget it until the day she died. They both knew that, but sometimes a rhetorical question just needs to be asked.
        "W-well, I - I hadn't felt it in a while at that point, but I felt it real bad that time. I - God, I almost came all over myself with you right there watching me, and you guys wouldn't let me touch myself so I'd have the excuse... if Eric had been able to hold off coming for like five seconds longer..."
He shook his head as if banishing the mental image.
        "A-and then, the last time we did it..."
There were tears in the corners of his eyes now, as he finally directed all his attention towards the fear that he'd actively been trying not to think about for months now.
        "Oh God, Annie... he was holding my hands so I would have no excuse, but it felt so good, I really, really didn't care, I just wanted to come... I was acting like a - like a giant slut, p-pushing back at him and stuff, I didn't care what happened as long as it felt good. I can't believe Eric thought I got off by humping the bed, I almost wish he [i]had [/i]figured it out, at least then it would be over..."
Embarrassed, the shepherd let out a sound about halfway between a cough and a sob.
        "Oh, Annie... what does it mean? Am I really in love with Eric? Am I gay? I - I'm so submissive with everybody, I don't want to be anyone's bitch!"

As he let out a pitiful whine, on the verge of tears, Anne gently rolled him off of her, and pulled him up the bed so she could embrace him, face to face, gently rubbing his back as she whispered in his ear.
        "It's okay, little brother, everything's going to be just fine, I promise."
Milo held her tightly, eyes screwed shut. She was so soft and warm, but what he felt had nothing to do with the fact that they'd made love in the not-too-distant past, it was all about the way she used to comfort him when they were children, just holding him very much like this, putting him at ease so he could fall asleep in her arms. Suddenly, a specific fear surged through him, and he leaned back to look at her, shivering against her.
        "Oh, God, Annie, please don't tell Eric! If he finds out..."
She leaned forward to kiss him on the cheek, her voice still soft and soothing.
        "He'll what, Milo? Call you a faggot and never speak to you again? Beat the shit out of you for enjoying it? He's your [i]brother[/i], Milo, and he loves you very much, you know that. And he was the one who [i]made [/i]you come by bottoming, in case you'd forgotten, your little problem doesn't exist in a vacuum."
        "B-but... it wasn't supposed to be anything [i]real[/i], Annie, we were just supposed to be helping each other unwind, doing a little stress relief..."
Gently cradling his head, she pressed her forehead against his, something she'd done as a child when she claimed she was letting him borrow some of her bravery so he could go back to sleep without worrying about nightmares. 
        "Calm down, Milo. Deep breaths. Think this through. Do [i]you [/i]remember what happened after the first time I watched you two?"
Milo had fled to the shower, and Anne had snuck into his room while he was washing, so that he discovered her on his bed when he returned, clad only in a thin robe. What had followed had come naturally.
        "Uh-huh."
        "Well, you seemed pretty damned into that, little brother, I gotta say. And what about Gela? You lo- you care about her, don't you?"
His tense muscles slackened a bit as she lead him down this train of thought, which she took as a good sign.
        "...You never heard me say this, but yeah, you were right... I - Gela's [i]really[/i] important to me." 
She ignored the impulse to squee with girlish delight and set that aside for later.
        "You told me yourself that you'd never felt anything for any male except our brother, right? Whether or not what you've got going on with Eric is 'real', Milo, you can't be [i]gay[/i]. And I don't know if you've been hanging out in the bad part of the Internet or not, but contrary to anything you might read, you can't [i]make [/i]someone gay just by making them feel really good."
Personally, Anne believed that both of her brothers were bisexual, assumed they [i]had [/i]to be if they actually went as far as having sex, but that was one more topic for another time.

        "W-well, even if I'm, uh... [i]bi[/i]..."
He had to force the word out, and this close, Anne could literally feel the heat from his blush. 
        "...or whatever, I - I don't like the other thing, the coming-without-touching thing. I don't want to be a girly little bottom, sis, I don't..."
        "You don't [i]have [/i]to be anything you don't want to be, Milo."
That didn't seem to help much, and the shivering shepherd whimpered against her again.
She gave him a squeeze and thought for a moment, when something she hadn't thought about in quite some time occurred to her.
        "...Milo, can you tell me something? You said it doesn't feel crazy good every single time, right?"
        "Yeah, why?"
        "Well... when it [i]does [/i]feel that good, is it always like that from the beginning, or does it happen after you change positions or something?"
Milo leaned back again, frowning in the dim light. That hadn't occurred to him before, but now that he thought about it...
        "Uhh... yeah, actually, the first time Eric moved a bit, the second time you had us shift a little to get a better view, and the third time... Annie, do you know what this is?"
        "I think I might have an idea."
Hope shone in the younger canine's eyes, and his ears lifted themselves away from his skull. 
        "Please, Annie, I need to know, please!"
        "Well, I'm not certain, I'd need to perform a test to be sure." 
        "Wh-what kind of test?"
        "Well..."
        "Please, Annie?"
He was not above begging at this point, but fortunately she didn't make him go that far. 
        "I would need to, ah, feel you... inside."
His tail was already hanging down, curled between his thighs, but it twitched behind him, moving to more directly cover his rear entrance.
        "...Oh."
That made sense, given the nature of the problem, but it was still embarrassing. He closed his eyes, unable to look at her as he said it.
        "...Please, Annie? I - if it's too gross, that's okay, but..."
She moved away from him and he opened his eyes again, to see her reaching into the drawer on her bedside table, retrieving a clear plastic tube full of some kind of gel.
        "How could I say no? You're my little brother, and I want to help you."

She squeezed a little of the gel onto the first two fingers of her right hand, then put down the tube and hugged him again, careful not to press her slicked-up hand against his sleek pelt.
        "This is just a bit of lube to make it easier on you. Don't worry, I promise it's not the kind that warms up."
As she spoke, Anne's left hand gently ran down his back until it reached his pyjama pants. Very few clothing items were designed for a single Morphic species, and these pants were no exception. A small flap was opened to allow his tail to stick through, but snaps above and below allowed the opening to widen to accommodate wider tails, such as those of reptiles. Anne gently pushed her brother's tail aside, opening the snaps beneath its base to gain access to his flesh, and brought her right hand down to the tight ring of muscle hidden there.
        "Y-you know, I could take my pants [i]off [/i]if it would help."
        "That's okay, Milo, it's really for the best this way. Just relax."
Milo let out a different kind of whimper as his sister's well-lubricated fingers came into contact with his anus and gently pushed. The younger shepherd moaned quietly as Anne's fingers slowly but steadily pushed into his backside, whereupon she immediately began to rub along his inner walls.
        "Relax, Milo, I promise it won't hurt or anything." 
He squeezed his sister just a little harder for a moment, trying not to clench down on the intruding digits. Milo was now somewhat used to having something in his rear, though, and once he'd gotten over the initial odd sensation, he managed to fully relax, lying there and letting Anne gently finger him, hoping she'd be done soon. As her fingers gently slid in and out, rubbing against his inner walls from different angles, Milo began to notice a problem he hadn't anticipated, and began to blush just as vibrantly as he had while explaining his dream.
        "Ohh, uh, Annie? You're, uh, you're... it's making me hard."
He resisted the urge to cover his face in embarrassment, but his ears still flattened back down. As his penis continued to grow longer and fatter, pushing against the fabric of his PJs, Anne nuzzled against him. 
        "That's perfectly natural, sweetie, the butt is a very sensitive thing, don't you worry about it."
But worry he did, and despite his best efforts to try to resist by focusing on his shame or biting his tongue to distract him from the nice feelings, he was soon fully erect, his shaft proudly jutting forth, tenting out the tight material of his pants. No matter how much he tried to ignore it, Anne's probing fingers felt so good that he was slowly getting hot and bothered. The teenager lay there, trying to be still and ignore the pleasure, but there wasn't much else to focus on. For her part, Anne looked very professional, eyes unfocused, concentrating on what she was feeling, occasionally nodding knowingly.
        "Hmmm, that's [i]very[/i] interesting. If my hands weren't otherwise occupied, I'd be taking notes."
        "Wh-what is it?"
        "Shhh, relax, Milo, just close your eyes. Let me finish here, and then I'll tell you."

He shut his eyes, as she'd suggested, but that just made it even harder to ignore the pleasure her slender digits were wringing out of the most embarrassing part of his body. The shepherd felt himself throb in his pants, and swallowed a whimper. The following minutes passed in relative silence, as Anne continued her achingly slow exploration of her brother's rear. 
        [i]Oh God... why does it feel so good... it's just fingers... you always hear older dudes bitching about the doctor having to do this, it's not supposed to be sexy!
[/i]Milo twitched and shivered on the bed, wondering how he looked to his sister, when suddenly her fingers pushed a little harder against a certain spot and he gasped, eyes snapping open, a burst of pleasure spreading out from within him as he involuntarily clenched down on Anne's fingers. That wasn't a good sign. He recognized that feeling... it had preceded him blowing his load hand-free on both occasions. Blushing, he grinned nervously at his sister, who was raising an eyebrow.
        "S-sorry..."
        "Sorry? But whatever for, dear brother?" she asked mischievously, as though she hadn't been studying his every move and expression for the past five minutes.
      
Swallowing, he muttered 'never mind' and willed his legs to stop twitching. Maybe he hadn't actually made any noise, and she hadn't noticed. He didn't really have much time to think about it, as all thought was pushed from his mind when Anne added a third finger to his backside. He felt himself throbbing again, hard enough this time that he was pretty sure there would be a damp spot in his pants over the tip of his penis. He managed to gasp out a protest, grabbing on to his sister's wrist and momentarily halting her nimble fingers.
        "[i]Annie![/i]"
As before, she was all maternal benevolence, rubbing his cheek soothingly with her free hand and whispering to him.
        "It's okay, Milo, I'm almost done, you just have to hang on a little while longer."
He let go of her hand and let her continue fingering him, and barely resisted a moan; she was focusing all three of her fingers on that one spot, that one specific part of him that sent out those pulses of pleasure. Now he couldn't keep his legs still, and he reached out to grasp his sister's shoulders to resist the overpowering urge to masturbate and get some relief. It was all he could do to [i]not [/i]roll his hips, pushing back against her fingers.
        [i]Ah, God, she said she's almost done, but so am I! I - I [/i]can't[i], though, not like [/i]this![i] I - I have to keep fighting it, she'll be done any second... she's [/i]got [i]to be!
[/i]Milo so desperately wanted to finish himself off, get some relief, he was certain by now the tent in his pants would be stained with pre, he was throbbing now almost every time Anne's shockingly efficient fingers rubbed over that special spot. The young canid was doing his best to think of this as a clinical test, an uncomfortable experience to be endured for one's own good. But that just put the humiliating mental image of blowing his load at the doctor's office into his mind. Then there was that part of him that had caused all the worry in the first place, the part that wanted to give in, push back against his sister and jack off right then, right here, without any regard for the consequences. He was ignoring that impulse, but it seemed he might not have a choice. His hands tightened their grip on Anne's shoulders, his distraction causing him to miss the widening of her smile, and he realized, with a sinking feeling in the pit of his stomach, that he was rapidly approaching the point of no return, just as he had with his brother. He clenched his eyes shut as tight as he could, trembling against his sister; if he'd been able to form a coherent thought he might have wondered how she could possibly be ignoring this. Finally, he knew the moment was upon him, but he resisted right up until the very last second.
        "No... no... [i]nooooo![/i]"
Groaning out of both embarrassment and relief, Milo shuddered, hard, as his erection began throbbing and spasming in his pyjamas, his backside rhythmically clenching down on his sister's fingers, which kept wiggling inside him, rubbing hard against that mysterious spot that was giving him all this trouble. Desperate for more stimulation, Milo thrust his hips forward, pressing his groin against Anne's thigh and grinding as his penis spurted again and again, hot, wet canine semen jetting out to paint the inside of the shepherd's pants. With his worry, he hadn't taken care of business since the last time he and Eric had been together, so he found himself with a somewhat larger load than usual, but he barely noticed, continuing to thrust against his sister as he came and came, smearing his seed against his groin fur with the pressure.  

When Milo's climax had finally burned itself out, he slumped against the bed, his entire body going limp as he dully wondered when the world would stop spinning.  Anne looked very pleased with herself as she cleaned off her hand, using the conveniently placed tissues and sanitizing lotion on her bedside table. When she turned back to her brother, she was all smiles, but Milo felt lower than dirt.
        "...Sorry I ruined your test, Annie."
She laughed softly, for some reason, and gave him a sideways look.
        "Milo, what exactly did you think I was testing for in the first place?"
Suddenly it became very hard for Milo to work out what Anne looked like at all, as his eyes began to fill with tears.
        "S-so I guess it's true, then, and I can't fight it anymore... I... I really [i]am [/i]a sissy little bitch! I'm a s-submissive little b-bottom, and I'm j-just kidding mys-self with Gela..."
His voice had begun to hitch up, making it difficult to speak, but he forced himself to continue, ignoring whatever placations Anne was no doubt trying to give him.
        "Oh God... y-you were j-just using [i]fingers[/i], it wasn't even - it wasn't even supposed to be [i]sexy[/i], but I - I [i]came in my pants![/i]"
He shook his head as if trying to erase the memory. Anne tried to speak up again, but he cut her off.
        "I - I'm so sorry, Annie... Jesus, I was humping your leg like a fucking [i]feral[/i]... I should just ask Eric if I can be his omega, m-maybe it won't be so bad..."
He couldn't say anything more, sobbing bitterly, burying his face in his sister's shoulder and finally letting the tears flow. He held onto Anne tightly, unable to form coherent thoughts, just crying and shivering against her. For her part, Anne just hugged him tight, running her fingers through his fur and making soothing noises to his ear. It was not entirely unlike what she'd done for him after particularly bad dreams had gotten him this upset, just let him cry himself back to a state where he'd be able to comprehend her. After a minute or so, he was down to sad little sniffles, though he was still pressed against her, not in the mood to do anything except wallow in his own misery. It was then that Anne took her opportunity.
        "Oh Milo, I'm the one who should be sorry. That [i]was [/i]supposed to be sexy, I was [i]trying [/i]to make you lose it. I - I thought you'd figured that out on your own, thought you were just playing along. I feel like such an ass right now."
Milo was still having trouble holding back little sobs, but his ears twitched, perking up ever-so-slightly at these words, leaning back and looking up at her with mistrust, as if he suspected she was getting his hopes up before dashing them again.
        "Wh-what do you mean? What d-did you [i]do?[/i]"
Anne leaned over and kissed him on the nose.        
        "You wanted to know why bottoming makes you come, right? Well, I had a feeling I knew the reason, and that it [i]wasn't [/i]'you're a little bitch', but I couldn't be sure unless I tried, well, [i]that[/i]."
He let out a whine, grasping at the straws as she offered them.
        "Well?! I'm dying over here, Annie, please, you gotta tell me!"
She blinked.
        "Oh, you didn't figure it out? It's just prostate stimulation, little brother."
Milo shrugged helplessly, and she chuckled.
        "You know, it's [i]your[/i] body, you shouldn't know less than me about it."
He said nothing, but glared at her, blushing slightly.
        "Okay, okay, look, guys have a gland down near your junk, 's called the prostate."
The younger canine added a frown to his glare.
        "I've at least [i]heard [/i]of it, all those cancer charities and stuff."
        "Hey, you want an answer or not? Anyway, I don't know what the exact reason is, but the prostate is tied into your sex drive pretty deeply, so rubbing it is supposed to feel [i]crazy [/i]good. It's like the male version of the G-spot, basically. You lose it when you're bottoming because Eric's dick is rubbing against just the right spot. That's why it doesn't always happen, because when the angle is different, he isn't putting pressure right there."
Milo liked the sound of that, that it was just a physical thing, nothing to do with him being submissive or not, but something didn't quite add up. 
        "But... but Eric never ever came when I topped him, never even seemed close!"
Anne squeezed him tight.
        "Well, that's the thing, most guys don't, your prostate must be extra-sensitive, or closer to the, uh, surface, or something. It's like how some people have a really weak sense of smell, don't worry about it. It's super rare to be able to come from bottoming, actually, a lot of guys would be [i]jealous[/i] of you."
Milo blushed self-consciously at that, smiling thinly. He did, however, make a conscious effort not to think about the [i]type [/i]of guy who would be jealous of him.

It was hard to believe there was a totally reasonable explanation for the 'problem' that had been worrying him for so long. 
        "...So, I'm [i]not [/i]a submissive little butt-slut?"
She chuckled softly and scratched him behind an ear.
        "Oh, you're [i]definitely [/i]submissive, Milo, there's no getting around that. But that's not a [i]bad[/i] thing, it's just who you are. But to answer your question, [i]no[/i], you're not a 'butt-slut' or whatever you want to call it."
Milo bristled briefly at how quickly she had acted to confirm his subby nature, but he was self-aware enough that he wasn't terribly bothered by that. His brow furrowed as something occurred to him, now that he had time to think.
        "...Annie, thanks for the revelation and everything, but did you have to teach this particular life lesson by making me cream my pants?"
The elder shepherd giggled and then shrugged.
        "Hey, can you blame a girl for mixing business with pleasure? God, that was so hot..."
        "How did you even know how to do that in the [i]first [/i]place?"
She winked at him.
        "Girl's got to have her secrets. Maybe I had an ex who was really into that, hmm? Showed me how to get him off? The world may never know."
Grinning along with her, Milo leaned in and hugged her tight. 
        "Well, thanks for helping me, Annie, this has been bugging me for so long now.... kind of a 'weight of the world' thing." 
She kissed her brother on the cheek and winked at him.
        "Happy birthday, Milo."
He frowned slightly, and was about to point out the obvious fact that it was [i]not [/i]that festive occasion, when she continued.
        "...And Christmas, and New Year's, and pretty much any other holiday for the next year or so. Lifting the weight of the world ought to cover me for a while now."
The siblings cuddled in silence for a moment, just enjoying the warmth of another body so close to theirs, and then Milo spoke up again. 
        "Really, though, Annie, if there's anything I can do to pay you back, you just let me know."
He winked at her, finally relaxed again, even adding a joke.
        "Just as long as you don't charge me interest for a favour this big."
To his surprise, for just a moment, Anne let the veneer of supreme confidence he so admired about her drop, and she looked uncertain, even hesitant, biting her lip and suddenly avoiding eye contact.
        "Well... um... I wouldn't want you to do anything special, Milo. I didn't do any of this just so that I could get something back."
        "Come on, sis, I want to thank you for what you did for me."
She looked back at him, blushing, which was an interesting change of pace.
        "Well, there is [i]one [/i]thing..."
He grinned.
        "What's that?"
        "I didn't want to interrupt this warm sibling moment, but I suppose it wouldn't be that much of a stretch given how we [i]got [/i]here. I kinda wasn't expecting exactly how, uh, [i]hot[/i], getting you off hands-free would be. God, I'm so turned on I can barely stand it! I was gonna wait until you went back to your room so I could play with myself, but if you wouldn't mind, I'm sure you could help me scratch that itch in a [i]much[/i] more satisfying way."
Milo started blushing and Anne smiled, her confidence returned, and things between the two siblings were back to normal.
        "Um, I'm sure that would be nice and all, Annie, but you kinda just got me off, remember? I don't think I can get it up again this fast..."
Putting on an almost predatory grin, the female shepherd released her brother from her embrace and began to move down the bed.
        "Oh, we've got all night, Milo, don't you worry..."
Gently taking hold of the waistband of her brother's pants, Anne began to tug them down. 
        "There we go, much better. It's the middle of summer anyway, you won't be needing these..."

Milo shivered, partially at the hungry look in his sister's eyes, and partially at the unabashed way she was staring at what were ostensibly his private parts. Despite the fact that sleeping with his siblings had somehow become routine, he still blushed; somehow it felt different when his penis and balls were slick and shiny with his still-warm seed, the fur on his groin matted and sticky. And, much to his dismay, it was still a relatively unfamiliar experience to be exposed before a female. His blush intensified when Anne started using her soothing maternal voice.
        "Ooooh, poor dear, you've made such a [i]mess[/i] of yourself. I'll just have to take care of that for you, don't you worry."
She had made no move towards the tissues next to her bed, which confused him slightly. Milo thought about pointing out that it wasn't really his fault that he'd emptied his balls into his pants, but said nothing, wanting to see her next move. He squirmed a little as she held his pants up to her face, taking a deep, brazen sniff of the damp patch over the crotch, savouring the scent of his release. He actually gasped when she turned the material over and gave the sticky side a quick lick with her wide, flat tongue. 
        "Annie!"
She gave him that smile again, and winked.
        "You know, little brother, I'm [i]hardly [/i]a connoisseur, but you taste pretty good."
Casually tossing his pants onto the floor, Anne leaned down towards his crotch and gave her brother's penis a lick. Milo shuddered, but his soft manhood did not stir. 
        "I - I told you, Annie, I just came, I can't get it up again!"
        "I'm not trying to get you hard, sweetie, I'm just cleaning you up!"
With that, she began to lick at Milo's cock and balls, lapping up the canine sperm as her brother moaned. It was a very strange sensation for Milo, having a warm-blooded female energetically licking at his genitals while his dick stubbornly remained completely flaccid. The only reaction she was able to get out of it was to make it throb, drooling out some leftover come, which she promptly lapped up. Once Milo's naughty bits were clean, shining with her saliva, Anne moved on to his fur, licking him as though she was a feral cat grooming her mate... or her young. As she continued working, Milo considered the fact that Gela flatly refused to perform oral on him, even though he'd given her that favour a few times now. He didn't mind it, really, it had been his idea, and he liked doing it, so it wasn't like she was demanding he eat her out without any compensation. [i]Besides[/i], he thought to himself rather sarcastically, [i]I'm waaaay too submissive to push the issue, right sis?[/i] Then, pushing the mouse out of his mind while he was with another female, it occurred to him that it was probably appropriate, then, that a girl was finally giving him some mouth-loving, and he couldn't even get hard and fully enjoy it.
        "This is adorable, Milo, stays all soft and cute no matter what I do to you."
Amusement shining in her eyes, Anne took his phallus into her mouth and ran her tongue around it, to no avail. Quickly releasing him, she leaned back to look at her handiwork. She had cleaned up all the visible semen, and gotten most of his fur smoothed down. It would probably take a shower to get him fully presentable again, but he was much cleaner than he'd been before.  

        "Perfect."
Anne began to move up the bed again, beaming at her brother once she was at eye level again, taking hold of his hands and placing them on the waistband of her own pyjama pants, her intentions obvious. Not waiting for a written invitation, Milo eagerly pulled his sister's pants down, slowing a moment when her treasures came into view; looking upon the core of femininity had not yet become a routine occurrence to the shepherd, so he found himself staring with something approaching awe. Even in the dim light he could see that her lips were already slick with arousal. He hurried to tug her pants off, but when he reached for her, she stopped him, pulling him in close and pressing her lips against his. With a shudder, Milo relaxed in her grip and began to kiss his sister. With that, Anne's hand slipped down her brother's lean body, gently taking hold of Milo's penis, squeezing and kneading it as her tongue explored his mouth. Milo wasn't sure which was more distracting; Anne's lips, which were softer than he'd known was even possible, her nimble tongue, or the hand massaging his genitals. That hand soon moved down to his testicles, rolling his balls around in the palm of her hand and squeezing ever-so-lightly, so that it felt good instead of causing him terrible pain. Milo realized suddenly that he hadn't even flinched when she took hold of his boys, his trust in his big sister was absolute. He felt Anne take one of his hands in her own, and he wasn't terribly surprised when she pressed it between her legs. He began to run his fingers up and down his sister's lust-soaked lips, shivering as he felt her pushing back against his hand, eager for his touch. It had taken several sessions with Gela before she had allowed herself that kind of enthusiasm for his ministrations, subconscious as they were. Anne's pussy was absolutely [i]drenched [/i]with arousal, much warmer than he was expecting it to be. Not for the first time, Milo wondered how Anne was so very good at hiding it when she was horny. For a time, he closed his eyes and lost himself to the sensations, pushing his fingers between his sister's labia and feeling around, revelling in the unique textures and shape of her inner walls, feeling the fur on his fingers becoming saturated with her juices. If Anne was at all disappointed with his amateur fumbling, she made no indication of it, even groaning appreciatively when he moved a thumb to rub and stroke at her clitoris, once it had emerged from its hood and made its presence known. Eventually, Milo's eyes fluttered open again as he felt his penis finally waking up from its slumber, twitching and growing in his sister's oh-so-soft grip. Anne broke off the kiss with a triumphant giggle.
        "Ah, finally! I was beginning to wonder if maybe you were right about those dreams after all."
She immediately licked his nose and winked at him, so he had no time to be crushed or embarrassed by her comment before he felt the humour in it. As his erection reached its full pride, Anne began to stroke him gently as she gave him a look that could only be described as "bedroom eyes", a phrase Milo had heard but never truly understood before this night.
        "You know, you're getting pretty hard for a guy who was worried he might be gay such a short time ago, Milo. I know you were embarrassed that time I said your dick was 'cute', but it's also nice and big..."
The younger shepherd shuddered at these words coming from his own sister, adding a groan when she punctuated her statement by gently licking the tip of his sensitive prick. 
        "Mmmm... You know, I thought I had a major preference for guys with knots, but yours is growing on me all the same. Heh, pun not intended. Now..."
She leaned in towards him, whispering directly into his ear, her voice breathy and full of need, but not before teasing him by licking the skin inside. 
        "...Why don't you put this beautiful prick to good use, hmm? I've got a suggestion for you if you can't think of anything..."
She didn't add any physical stimulation to this, so Milo's subsequent moan was caused entirely by the words and who was saying them to him.
        "...[i]Fuck me.[/i]"[i] 

[/i]In response, Milo could only nod, hopelessly turned on. Anne began to move, lifting a leg to move over her brother.
        "Last time you were on top, so this time I'll do the work, okay?"
To her surprise, Milo put a hand on her leg, stopping her.
        "W-wait, Annie... C-can [I]I [/I]be on top instead? Please?"
He desperately hoped she wouldn't ask the reason for this request, which was simple, though embarrassing; every single time he'd made love to his tomboy friend, without exception, Gela had insisted on being on top, wanting to be in control, and Milo, naturally, had given in without a word. To his relief, although she cocked an eyebrow ever-so-slightly, she just nodded.
        "Sure thing, sweetie, whatever you want."
As Milo got up on all fours, she finally tugged her shirt off, tossing it to the floor with their other pyjamas. 
        "Ahh, that's much better..."
The trembling shepherd crawled up the bed, barely able to contain his excitement as he positioned himself above his sister. She reached up and put her hands behind her head, letting him take in the sight of her in its fullness. 
        "What do you think, little brother?"
He shivered as he positioned himself between her legs. 
        "Y-you're so pretty, Annie..."
He trailed off after that, but the awe in his eyes made up for the simplicity of his compliment. He lowered himself towards her, a little awkward about it due to his inexperience, and took hold of his hard-on, carefully positioning himself at her entrance. As she felt the head of his cock nudging at her slit, Anne smiled, wondering if her brother was aware just how energetically his tail was wagging. 
        "That's it, Milo, we're both ready, so just take me whenever you're ready."
He shuddered visibly at her casually lusty words, but then stopped, revelation in his eyes, and he pulled back. Anne groaned in frustration; despite her generally cool exterior, she [i]really, really [/i]needed a good old fashioned dicking tonight. 
        "What's wrong, sweetie?"
        "We need to get a condom, Annie! Where do you keep them?"
She made a face, remembering something of her own. 
        "Oh shit, I'm out! I [i]knew [/i]I forgot something at the pharmacy today!"
Milo bit his lip, showing an impressive amount of hesitation for his level of arousal.
        "Please, Milo, I'm on the pill, remember? We can do it anyway!"
The slender shepherd narrowed his eyes and gave her a sideways glance.
        "Well... you'd better not make a joke about getting knocked up again, that was [i]not [/i]cool..."
        "I won't, I promise! Come here, sweetie..."
Relenting to her needy, honest eyes, Milo bent back down and moved back into position, placing a hand on her hip, bracing himself against her. Then, he took a deep breath, and shoved his hips forward, driving himself into his sister's passage, which eagerly spread to welcome him inside. Anne moaned with delight as Milo hilted himself within her wet warmth, wrapping her arms around him and holding him tight.
        "God, [i]yes[/i]... This is so hot... I wonder if I'll ever get used to the idea of... of fucking my brothers. Christ, I hope not..."
Her own tail was now trying its level best to wag, despite being pinned beneath her back and the bed. She pushed up at Milo with her hips, encouraging him to get started, and he obediently pulled back before pushing home, the feeling of Milo's rigid prick rubbing against her inner walls turning her on just as much as the knowledge that she was making love to her sweet little brother. Milo, for his part, practically moaned himself just from the intense warmth of his sister's tight, slick channel around his erection. As if she was reading his mind, the next time he hilted himself Anne clenched down, her vagina squeezing the entire length of his prick, and he cried out in pleasure. She giggled and reached up, touching his cheek.
        "Easy, little guy, don't want to wake up mom and dad. Here, I've got something for your mouth to do anyway..."
Moving her hand to the back of his head, she gently pushed down, leading his muzzle to one of her full, round breasts. Obediently, he closed his lips around her achingly stiff nipple and began to suckle, teasing the sensitive flesh with his tongue. Gela got oddly self-conscious when he paid this much attention to her breasts, even given what they had already done together, so he was glad Anne actively encouraged him to play with her. Now, as he suckled on one teat and squeezed the other with a free hand, she whimpered, bucking her hips up at him to meet his thrusts, clearly getting more aroused. With a gasp, Milo pulled his mouth from his sister's breast, saliva momentarily bridging the gap between his lip and her nipple, before he sheepishly wiped it off and moved to her other teat. She smiled at this.
        "It's so cute that you blush even when you're fucking, you know that?"
He shot her a look, but the corners of his mouth were turned up.

Both siblings lost all sense of time as they made love; all that mattered was pleasing each other as best they could. Milo switched back and forth between his sister's breasts, squeezing her mounds as he licked and suckled at her nipples. He felt himself throb, deep inside her, and did a pretty good approximation of moaning through his nose. He felt Anne's hand on his shoulder and looked up at her; she was biting her lip, looked oddly desperate.
        "P-please, Milo, my clit, you haven't been touching my clit..."
He broke off the seal of his lips just long enough to apologize as he ran his hand along her smooth abdomen.
        "Sorry, Annie. I forgot."
She sucked in a shuddery breath as his fingers found her throbbing love button, and shuddered against him.
        "Th-that's okay, Milo, that's why I'm t-teaching you..." 
He was slightly distracted, focusing on his fingerwork, and pulled back too far, slipping out of his sister's velvet warmth entirely, slapping the bottom of his cock, now gleaming with her juices, against her lips, dark and swollen with desire. So caught up in the feelings, Milo actually whimpered with the strength of his need to return to her embrace, but to his surprise, Anne was already on it, reaching down and taking hold of his prick, quickly lining him up so that he could get right back to it, burying his cock deep in her folds. The shepherds continued their incestuous coupling with even more vigour than before, Milo doing his best to multi-task, suckling at his sister's breasts even as he pushed into her again and again, all the while squeezing and rubbing at her throbbing clitoris. Anne was pushing up at him, one hand curling into a fist, bunching up the sheets beneath her, the other stroking Milo's back as if offering encouragement to a pet feral, whimpering a litany of quiet praise to her brother as he rutted her. He throbbed again, stronger this time, and released his sister's flesh from his mouth in order to moan.
        "Oh - oh God, Annie... I'm getting close, I'm gonna coooome..."

Anne was getting fairly close herself, at least as much from the taboo situation as from Milo's energetic attempts to pleasure her, so instead of asking him to hold back, she just whimpered, before whispering in his ear, getting him even [i]more [/i]worked up.
        "Jesus, [i]yes[/i], d-do it, Milo, give a nice messy finish for your big sister, I - I want to feel you coming inside me!"
Shuddering against her, Milo let out a wordless groan, wanting very much to fulfill her wishes, leading him to redouble his efforts, slamming home with each thrust, his balls gently slapping against his sister's pelvis. Anne gasped hard as he shifted to this more energetic coupling, holding him tight against her, fingers gathering fistfuls of fur, hissing out a long, low [i]yesssss[/i] as she felt her arousal building to a crescendo. By this point, Milo was breathing so hard he couldn't keep his lips closed around his sister's nipples, so he just closed his eyes, focusing on the feelings and allowing himself to whimper and moan; at this point he barely felt the embarrassment, and he knew Anne would find it both endearing and arousing. As his release hurtled closer and closer, the noises he was making became somewhat higher-pitched, and his legs began to shake. At the last second, Milo rammed home, driving himself as deep into his sister's tight channel as he could. No sooner had he hilted himself when Anne threw a leg around his waist, holding him tightly against her heated body, preventing him from withdrawing even the slightest bit. Not that he wanted to, of course, as his orgasm finally exploded through him, his instincts demanded he stay as deep as possible; had Milo been born with an 'inherited' prick, anatomically similar to that of a feral, he no doubt would have had quite the struggle to fight the urge to tie with his sister, as morphic canine culture put a great deal of significance on who one knotted with. As his penis was more or less the same as a human's, though, he was free to just let go, losing himself in the sensations of climax. Such as Anne's surreptitiously lubricated finger pushing under his tail and finding passage into his rear, pressing hard against that 'P-spot' just as he began to unload himself into her velvet heat. His cock throbbed deep within Anne's warmth, shooting long, ropey strands of hot canine seed into his sister's body, feeling her vagina clenching and squeezing down on him, tenderly stimulating every inch of his spurting prick, encouraging him to come even harder. In fact, as he came, Anne felt Milo shuddering against her, fingers still frantically working her clitoris, felt his backside clenching down on her teasing finger, and most of all felt the telltale heat of her brother's sperm spreading deep inside her, and, just as she had hoped, he pulled her over the edge with him. The elder shepherd clamped her free hand over her muzzle to muffle the cry of pleasure she let out as she briefly arched her back off the bed, lifting her shivering brother with her, her inner walls clenching and trembling against his spasming length, milking his erection so expertly Milo momentarily wondered if she had as much control over her pussy as she did her fingers. 

The siblings shivered and moaned together until their orgasms finally ended, Anne's internal convulsions calming down and Milo's ejaculation ebbing to a trickle before ceasing altogether. Both Thompsons went slack together, tired and sweaty and happy, basking in afterglow, the scent of their lovemaking heavy in the air. Anne removed her finger from her brother's rear, reaching over to her bedside table to cleanse her hand once more, but other than that they remained just as they were. She gently ran her other hand along her brother's back, petting him like a feral. Milo, meanwhile, had nuzzled his cheek against her chest, resting his head upon her breasts as though they were pillows, savouring the feeling of closeness he felt with the sibling who had become his lover. They stayed that way for several minutes, and then Anne laughed tiredly, breaking the silence. 
        "Jesus, did I ever need that. Thank you, Milo, I haven't come that hard in weeks."
Looking up at her face, he grinned even as he blushed. In truth, he had actually come harder just earlier, when she was fingering him, even though he had enjoyed this session much more overall. He had only just learned the reason for his anxieties, though, so they were hard to let go of, and he couldn't bring himself to admit that.
        "M-me neither, usually I have to save up for a couple of days for it to feel like that."
Pushing himself up, letting his half-deflated prick slide out of her tired vulva, shivering as he saw that it was glistening with a mixture of their love fluids, Milo swung his legs over the side of the bed and sat up. 
        "W-well, I really enjoyed that, Annie, but I should really get back to my own room, mom and dad will be getting up in a couple hours. Th-"
He stopped mid-word as he felt his sister's arms wrap around him from behind. 
        "[i]Relax[/i], little brother. You don't have to go anywhere. I saw you close your door as you left, and it's a weekend, nobody's gonna be looking for you in the morning."
He allowed himself to be pulled back down to the bed, and back towards her warm embrace.
        "All you need to do is lie here with me and fall asleep."
        "C-can I get my pants first?"
She giggled, teasingly nipping at his ear.
        "The ones you just creamed? You're a morphic, Milo, do as your ancestors did. Unlike you and Eric, I made sure the door's locked, no one's going to walk in on us."
He smiled as she gently pulled the blanket over their bodies, even though she couldn't see it. 
        "I've never slept naked before, feels weird... kinda nice."
To his minor chagrin, Anne snuggled up tight behind him, hugging him close against her chest.  
        "I guess I [i]am [/i]submissive, even with you I'm the little spoon."
She giggled happily behind him, and whispered in his ear.
        "Really? Angela's a lot smaller than you, she'd look ridiculous as the big spoon."
While this was true, as the relative physiques of morphic canines and rodents were very different, there was no doubt in Milo's mind that his fiery lo - [i]friend[/i] could kick his butt if she really wanted to. 
        "A-actually, Gela doesn't like to cuddle, usually goes for the shower as soon as we're done."
He blushed. He hadn't meant to be so candid about the goings-on with his friend. Anne giggled again, and didn't comment on his slip-up.
        "That's a shame, cuddling afterward is practically the best part."
Feeling his sister's warm body pressed up against his, combined with the natural instinct to fall asleep after an orgasm, Milo found he couldn't argue with that.
        "Annie? Thanks again for telling - for showing me what was going on."
        "Don't mention it, Milo. I'm glad to help."
A moment of silence, and then;
        "Ummm... could you... could you not mention it to Eric though? I'm - I'm not ready to tell him that I... that I enjoy being the bottom. Not yet."
He appreciated that there was no trace of the earlier giggle in her response.
        "You have nothing to be ashamed of, Milo."
        "I know, I know, it's just kinda hard getting used to."
She squeezed him gently for a moment.
        "I won't say a word, you don't have to worry."
        "Thanks."
Anne leaned forward, reaching out to turn off her bedside reading lamp, and they just lay like that for a while in the dark. Then, Anne chuckled again, more softly this time.
        "Ohhh, little brother, I can feel you running out of me. You're really productive, you know that?"
He grinned and snuggled back against her. 
        "Eric, actually, he was impressed."
They both snickered at the secrets the Thompson siblings shared. For the first time in months, Milo felt completely at ease, his burden lifted. All was well with the world as he began to drift off in his sister's arms, and he was just about gone when she spoke up again, even more faint this time, obviously starting to go herself.
        "You really came hard from that prostate stuff, Milo..."
And then, she said something that snapped his eyes open, suddenly wide awake.

        "...Maybe next time we should try pegging."
