Leo had just finished peeking through the house trying to be as unsuspecting and quiet as possible while ensuring that the house was empty of other people so he could delve into a guilty favorite of a pass time for him. Which of course was cross-dressing his lithe, curvy frame was the peak of girly looking with wide hips and a bouncing bubbly ass, longer than normal hair it was no coincidence that he’d been mistaken for a girl numerous times even from the front but a more thorough inspection would should that his face wasn’t quite as soft and round as it could be and his voice was just a touch too deep to be truly feminine, naturally the “biggest” give away for him was the tiny package that he was currently tucking into a pair of blue and white striped panties, which barely even seemed to bulge out the fabric while flaccid his thumb was bigger than it and even when he was hard it didn’t make much difference but he tried not to let it get him down after all size doesn’t matter when you’re with a girl he could do plenty to please one. He finished getting dressed up rather quickly a pair of stretchy yoga shorts that hugged his girly ass tight while up top was a loose-fitting white blouse just to complete the look he dabbled in the bits of makeup he had, throwing on a small coat of mascara and some bright pink lip gloss for good measure. After all that work it was then he heard a knock at the front door and his stomach dropped wondering who it could be coming around the house, looking at himself in the mirror he could see that even at 14 he looked womanly, gifted in every way except for his male bits but through looking at that hard work he couldn’t help but wonder at answering the door like this, just to see the reaction… to test the limits of what he was willing to do and before he had time to talk himself out of it he was moving downstairs. 

Sam was grumbling to himself when he finally started walking up to the front door of the house, his size went past massive and into the realm of obscene,  the top of his head would nearly be touching the top of any door frame he went through as such he would tower over just about anyone else but if that wasn’t enough he was built like a flesh and blood tank with thick muscle obvious and defined over his arms and legs, in fact, the only part of him that wasn’t rippling with muscle would be his gut with extended out to expose an obvious enjoyment of beer. Perhaps his most striking feature though is the fat bulge that pressed out against the front of his pants a true monster just waiting to be released; Which coincidentally is what he thought was going to happen when Leo’s mother had given him a call, she is the latest of many such flings and while it was disappointing to hear that she wanted him to watch her kid for a bit while she was gone overnight after some car troubles on a work trip they’d worked out an agreement that involved her acting as his slave for a week afterward, making it abundantly clear that she’d need to find a place for her kid to stay because he was going to get the most out of it but she’d agreed sounding just a bit excited for it herself this is what finally led him to knocking on the door just planning to say “ Hi” explain the situation and set the kid to him own devices, order a pizza later for him, make sure the house doesn’t burn down while he sees how many of Leo’s mom’s clothes that he can ruin with his endless musky seed. Naturally when the door opened and Sam caught sight of a tiny, plump downright womanly figure greeting him his spirits lifted visibly as his eyes dragged up and down Leo’s body obviously sizing himself up against the supposed girl in front of him and just like that Sam’s thoughts turned to think that maybe he would have a warm hole to empty his nuts in after all and someone to make him dinner, after all, that would make an excellent payment for making him come out here on such short notice just too look after her brat!

Leo’s words died on his lips as he was forced to look up at the massive wall of muscle and fur that was standing over him, eyes going wide while trying to imagine just how strong someone like that could be and more importantly why they were there in the first place, Leo couldn’t place the fact that he was seeing a range of emotions passing over his face quickly while he continued to stare but the smell coming off the man was certainly distinctive he’d gotten a whiff of a more potent version every time he came home from school on Friday and walked by his mothers room
“Umm... Hello... Can I help you?” Leo called out in his soft off feminine voice trying to get an idea of what was going on, while shrinking down to a lower height nervously unable to stand tall at the gaze staring down at him, the sudden deep, booming voice coming out of Sam was nearly enough to make him squeak
“ Yeah, I’m here to babysit you, Lisa called me and said that you needed some supervision, she certainly didn’t mention she had a little girl though. So you better listen to what I say when I say it.” Sam spoke calmly just managing to hold back the wild arousal that was seeking to drip into his tone just hearing Leo talk made Sam want to jump forward and put it better use already but he restrained himself, thinking that it could end up being much more fun to play along with it, he had all the time in the world to toy around so why not. 

Leo was dreading having to say anything while Sam was speaking, hearing himself referred to as a girl was equal parts exciting that his dressing could work so well and nerve-wracking that he’d have to correct the gargantuan musky man standing before him but he couldn’t let the misunderstanding go on he was most certainly a boy after all
 “Well um.. Sir? I’m actually a... Boy..” Leo spoke softly while stumbling over his words, using sir because he wasn’t sure what else to say without knowing the man's name but he was quickly interrupted with a little grunt as Sam examined him closer clearly giving his face another inspection before he realized that Leo was telling the truth and while his smile initially faded it was brought back even brighter after a few more seconds
 “ Yeah right, you’re as much of a boy as I am a girl, don’t matter what you got, no boy dresses up like that and the name’s Sam, kid ask your mom about me,” He said, finishing with almost a teasing growl as he finally stepped inside the house without permission and shut the door behind him, he was already walking along to the living room without a second glance Leo’s way silencing his skittish protests with a wave of his hand directing the boy to follow him.

Once in the living room, Sam wasted no time in plopping down on the love seat closest to him, taking up nearly the entire thing as he went for the remote letting off such dominant controlling energy that Leo wasn’t even sure what to do fear crept into his mind as he imagined all the ways that Sam could hurt or maim him with barely and effort, looking like a bear in a canine's body and once again without even looking at Leo who was standing nervously half was across the living room unsure of what he should be doing after following Sam’s command to follow 
“ Your mom keeps some beers for me in the fridge, go get em’ then you can plop yourself right here.” Sam rumbled out while patting the sliver of couch that was free beside him, naturally not bothering to say please as it was just expected that Leo would just to it and be grateful for the opportunity, Leo barely even realized that he’d hoped to complete the task before he was rooting around in the fridge until he tugged out a small case of expensive beer, His mom didn’t drink so it would seem that he wasn’t lying about this, which of course added to the credibility of being here to babysit instead of just robbing them blind. Leo hauled the case of beer back into the living room with obvious effort as he wasn’t exactly drowning in upper body strength but soon enough Sam was reaching forward to grab it and set it on the table already tearing into it and cracking the first can he found, flicking his head to the side once again telling Leo to sit himself down, Leo did so quickly feeling more nervous by the second about disobeying Sam which is why he didn’t even speak up as he was nearly crushed against the side of the couch, his hips just barely able to fit while Sam leaned back with a load groan damn near chugging his beer as his arms splayed out on the couch, one powerful arm laying across Leo’s shoulder made it a struggle to sit upright, he couldn’t even imagine how anyone could deal with this beast of a man.

 Sam was pounding back the beers as he always did when he was at this house, commanding Leo to pass him another as soon as he was finished with one while he was using the remote to go through some of the saved videos that he knew would be in the memory while looking for it he thought once again about just giving up the play and just bending the “girl” Over so he could go to town but he fought down the urge as he knew that it would be more fun in the long rung to break Leo down
“So seein’ as I’m going to have to look after you, I thought we could watch a home movie that me and your mom made, I think you’ll like it” The lewd grunt that followed had Leo thinking that this could only mean one thing and his suspicions were proven correct as the screen flared to life with an image of his mother… 

 Nude and laying on her back the camera panning down to show off Sam’s massive cock, the fat organ throbbing and drooling copious amounts of thick musky pre down her body to soak into the bed sheets. By now Leo’s blood was pumping in his ears as his cheeks flushed with color unsure of how to deal with this situation as he was all but forced to watch his mother get fucked harshly, Sam was hurling a stream of insults and demeaning things while getting physical often, slapping her, tugging on her hair even going as far to spit on her face but through all of it she was squealing and all but begging for more even of the abuse, clearly she had some interests that Leo had no idea about. While his eyes were locked to the TV screen, Sam prevented him from turning his head away or even closing his eyes. A familiar potent stench began to rise into the air as out of the corner of his eye Leo could see the same fat breeding tool that was attempting to break his mom was rising high with a pearly bead of pre on the tip, Sam using his free hand to lazily stroke it while finishing off his sixth beer tossing them into a small pile he’d made on the floor as if he owned the place, His low arousal drenched voice sounding out of his chest like the rumble of thunder
“ Fuck, your mom looks nice, you shoulda' heard her the first few times  I tore up that bedroom, she was squealing so loud people down the block could hear it, begging me to wear a condom too but after a few hours of going raw she could barely say her own name” Sam finished with a little chuckle his large hand reaching over to smear the thick pre he’d gotten on his hand over Leo’s clothing as a casual act of marking, his gaze turning to him with a deep grin as he continued speaking large hand already trailing down to grab at Leo’s much frailer wrist tugging it over to press against the throbbing flesh of his musky cock while the video played in the background, making it abundantly obvious what Sam wanted from Leo
“Hell I really wish I’d thought to take a video of your moms first time taking it up the ass, She was gettin’ all uppity with me so I crammed it in without a care and went to town, it was great even with her whining and crying about it when I was done she cleaned me off and said thank you like I taught her! You could learn a thing or two about pleasing a man from your mom” 

Leo could only shudder to feel utterly trapped as his hand was locked in place at the wrist by the steel strength grip that Sam was holding even all his struggling and tugging couldn’t even wiggle his arm before his soft hand was forced up against his fat throbbing cock, the heat alone was astonishing closely followed by the size of it, while his hand might have been small it couldn’t even come close to wrapping the entire way around the grith, Sam’s hand quickly starting to work long stroking motions utterly soaking his hand in reeking pre-used as lube for further stroking, Leo was naturally disgusted with what he was being made to do but any complaints died on his lips whenever he thought about the overwhelming strength and size difference between them, so with his mind moving a mile a second from fear, disgust, and unwillingness he hadn’t even noticed that Sam pulled his hand from his wrist Leo continuing to power along pumping his forearm up and down a mild burning already starting to run through his small muscles as he worked them.

Sam groaned softly at the stimulation sending little sparks of pleasure through his mind fat cock twitching in anticipation while spurting more pre by the second looking more like a fountain then any kind of dribbling Leo’s hand was already well and truly soaked in it the rest pooling down into his pants, the couch and even down to the floor adding the potent breeding aroma in the air giving Sam another sight to peek in at with Leo’s face twisting as he finally caught a good whiff of the stench his mom had become so addicted too
“Get both your hands to work and start pickin’ up the pace, your mom tried pulling something like this she’d be sore for a week!” Sam spoke, the threat he was making obvious even with Leo’s attention pulled in so many directions and so like he’d just been slapped Leo bristled no doubt in fear from the casual tone of it all and set to work with both small soft hands laboring and stroking as if his life depended on it and he was rewarded with many growls and grunts from Sam as his cock continued to spurt copious amounts of his pre until it looked as if a water bottle had been spilled in his lap the staining damp marks only growing larger by the second as finally, he felt himself getting close after nearly 15 minutes, Leo was heavily panting and whining along the entire way clearly this was the hardest he’d perhaps ever pushed himself and his muscled ached from it. So when Sam suddenly got up and his arms were allowed a small break Leo nearly cried out in bliss.
 That bliss was crushed as his vision was suddenly blocked by Sam’s body and he could see that massive bitch breaking cock throbbing and bouncing so close to his face, the potent scent coming off of it nearly made his eyes water as he was forced to breathe in deeply, Sam had taken over stroking his own cock and stared down with expectant arousal as Leo’s quivering face
 “ You best remember that your job is serving real men, your only purpose is being beneath me. So open wide!” Sam called out perhaps laying it on a bit thick, but he was in the mood for it as his swollen nuts tingled in excitement ready to unload some of their backed up payload, however stubbornly Leo refused his command keeping his lips firmly closed together which at the very least gave Sam the chance to do something that he loved… Which came as his cock whacked his cheek, a hard baton of flesh, quickly moving to repeat the action all over his face leaving a bright sheen of reeking pre and a feeling of being utterly demeaned like a toy. Just like that Leo’s mouth was opening just a fraction and Sam wasted no time in stroking himself to completion, a deep rumbling growl as his cock bounced and his balls clenched up large ropes of cum spurting out like a first hose, filling his mouth to its entirety before he dragged his cock around to properly coat his face and his clothes so much so that by the time he was finally tapering off Leo looked more cum than fur however Sam certainly wasn’t done with him as his large hand clamped over his mouth and nose just as it was looking like Leo was planning to spit out the musky goop that was assaulting his taste buds
“That’s awfully rude, What do you say when someone gives you a gift?” He spoke with an annoyed tone his intentions beyond obvious even as Leo began struggling against his hand the need to breathe intensely after all that physical exertion and there was only one way Sam’s hand was going to be moved, so with a few tears and a long whine Leo managed to swallow that mouthful of dirty seed leaving him panting and gasping for breath, looking like a well-used whore while Sam stood there waiting for the obvious.

“Thank you,” Leo said in an incredibly soft voice while continuing to pant, he looked up with misty eyes towards Sam hoping for some kind of break or chance to get away but what filled his vision was Sam’s fat bitch breaking cock, still hard, throbbing and ready for action; Clearly he wasn’t even close to being out of the woods yet.

Sam was being extraordinarily nice to Leo, giving him a few minutes of sitting there panting and whining to let his arms recover from their workout but any time Leo tried something more than that such as speaking Sam’s hard cock was slapping him across the face sometimes even turning back for two or three more before he seemingly learned his lesson about talking when Sam didn’t want to hear it 
“Now, get your ass up and go make me some dinner, I don’t care what it is long as there’s meat” Sam finished with his usual predatory smile before taking a step back and ushering Leo off towards the kitchen before he was up taking the stairs two at a time clearly going to do or grab something from upstairs.

This finally left Leo alone to whine to himself as he stood in the kitchen, face still smeared with potently musky seed and a few sore spots on his face from been slapped so much, but the real damage was to his pride, he’d always thought of himself as a boy even when he dressed up or toyed around with his tiny package, Sam though... He invalidated all of that showing Leo what a real man was like, how easy it was for Sam to utterly overpower him and plant him firmly in the position of a submissive bitch. Leo had no idea how deeply those feelings were sinking into him until he realized that he was doing exactly as Sam commanded working around the kitchen to prepare a meal after of course taking the time to wipe his face clean of all seed he could manage without a full shower. While pulling a package of two steaks from the fridge so he could really get to work he heard a little grumble through the ceiling and noises of rummaging about stopped, so Leo could only assume that Sam found what they were after, but that meant they’d be down soon and while that defiant spark was still burning in him, the thought of being subjected to further degradation and cock slapping spurred him to work. Within moments of getting the steaks into the pan for cooking Sam peeked his head in with a lewdly approving smile looking Leo up and down again before speaking
“You look just like your mom doing that, there might just be hope for you yet kid, tell me when my dinner is ready,” he said before retreating back into the living room to do something… most likely finish off that case of beer.

It had taken nearly half an hour but Leo was finally getting the last piece of the meal together, all things considered, he would have been very proud of making it at any other time but now he was just fearful that it wouldn’t be good enough; After having spent the last half hour listening to all sorts of grunts and groans from the living room which were mostly for show to keep him working he was still terrified of encouraging the wrath of Sam. So once everything was good and done Leo peeked into the living room to spot Sam just watching tv, empty beer cans tossed around the floor and there were even more stray ropes of seed spread around the room as if Sam had been stroking himself the entire time
“Ahh... Dinner is ready... Sam!” Leo said softly trying to keep the embarrassing fear out of his tone before retreating back into the kitchen and busying himself getting everything out of the pans and bowls they were cooked in. The sound of Sam’s footsteps got louder the closer he got until he was finally in the kitchen, Leo heard a little “Clink” as something was placed onto the floor but he didn’t dare look back until Sam was prowling his way closer his low voice coming out like a grumble “Not bad, looks like you’d make a decent wife after all” Finishing with a little chuckle he moved towards where both plates had been set up, piled nicely with food… only he took both one in each hand as he went towards the table setting the food down with a little grunt, leaving Leo dumbfounded just praying this wasn’t going where he thought it was because something other than cum could do his stomach good right now
“Uhh Sam, sir... You took both plates!” Leo called out trying not to sound as nervous as he felt standing up to Sam like this.

Sam barely even responded to Leo until after he’d torn into the meal focusing on eating big hunks of the steak before he finally chuckled hearing Leo’s gentle footfalls getting closer to the table seemingly working up the courage to take his complaining further but Sam was quick to nip that in the bud by nudging his head to the side and calling out 
“This is MY dinner kid, yours is over there and you better be thankful for it” 
Leo’s eyes followed the line Sam was trying to point out and his eyes widened in horror as laying on the ground was a metal dog bowl overflowing with pristine white musky seed, the name on the side was “FuckToy”. Leo’s panicked whine was all it took to set Sam off talking again his tone leaving no room for argument or further bargaining “ Stop whining, We’ll get you your own bowl later but your Moms is gonna enough for now and you better lick it clean cause that’s all your getting until I decide you’ve earned my cock down your throat. Now, eat up” Sam turned back to eating his delicious meal ignoring all the half complaints that Leo was sneaking out like he was trying his hardest to work up the courage to tell Sam off or disobey the command but all the same he was inching forward towards that bowl. 

Leo couldn’t believe that he was actually entertaining the idea of pressing his face into that bowl and eating Sam’s seed as if it were some kind of treat, several times he’d almost gotten up from his hands and knees ready to protest, run or even attack Sam if it came to that, but every time he thought to push through to doing it his bowels turned to water and he lost his nerve his mind flashing with an image of Sam to exasperate just how outclassed physically that he was. Staring down at that bowl Leo could feel his stomach growling and after taking a deep breath he was pushing his way forward whining like a baby all the while as he finally buried his snout in that bowl of seed sucking it up, only to start gagging instantly on the potent taste and the sheer slick goopiness of it, feeling like it clung to his throat in a thick sheet while his nose and eyes stung from the potent scent coming off of it every feeling of humiliation only getting more intense as he heard Sam enjoying the real food he worked so hard to make. 

It was hard to keep track of time while having to suffer eating a buffet of cum for dinner but soon enough he was lapping at the still-warm metal bowl cleaning up the last smears of seed inside of it, his stomach now gurgling with the weight of that meal of hot goop; Feeling as if he would just pass out after such an endeavor with his weight slumped up against the nearest wall, Sam was walking over wiping his face on a spare rag while looking down at Leo with a smile 
“ Well aren’t you a good little cumslut, I think that’s the name we’re gonna get put on your bowl” Sam finished speaking by grabbing the back of Leo’s blouse and giving him a tug, getting him up to his hands and knees before walking back to the living room motioning for him to follow just like that and Leo was far too weak to bother disobeying at this point so he unsteadily crawled after Sam resting himself against the couch while Sam continued to stay down at him hungrily eyes finally focusing lower down, on that plump girly ass that was just begging for some proper attention 
“ After such a big meal I gotta work some energy off, why don’t you drop your panties so I can see what kinda cute little hole you got” Sam called out with a little chuckle while reaching down to grab at Leo's hip and all but throw him stomach-down on an ottoman in front of the couch, his plump ass facing Sam.

With a deep whimper, Leo’s hands started dragging back to his rump, hands fumbling around with the waistband of the panties until they were coming down around his thighs until Sam took over and tugged them down to his ankles, Leo could feel Sam’s gaze weighing him like a piece of meat or a toy he wanted to use and while He wanted to struggle more to start squealing and trying to push himself out of such a revealing position his thoughts were suddenly interrupted as a sudden rush of pain and pleasure hit him like a freight train, two of Sam’s fat fingers just given a cursory spit soaking were being roughly pushed into his pink rosebud and quickly found their way to pressing against his prostate, a no mercy massage that had Leo squealing like a girl, his hole clenching down while his back arched, every muscle that could be tensing up as he tried to work through the overwhelming sensations. Sam though was seemingly eager to push it higher and higher  as he worked his fingers deeper, trying to spread them apart and work the clenching ring of muscle
‘’ To think you were spouting that nonsense about being a boy earlier but now, here you are squealing like a bitch in heat just getting your cunt fingered. You’ll realize soon all you’re good for is pleasing cocks”
Sam continued his assault until he finally felt a bit more give in his ring, the cute pink hole not closing up quite as much when he finally withdrew his slick fingers, however, it wasn’t long until that feeling was replaced with his massive cock head pressing up against that puckering hole, a liberal glaze of pre spread over it as lube while applying steady but forceful pressure there, Sam all too eager to give in to his instincts and deliver a harsh slap to Leo’s bubbly ass, even if it would no doubt make his initial penetration harder.

Leo felt as if this level of penetration should be impossible, that there was no way he could possibly take something so big but Sam was intended to prove that wrong as he pressed deeper a few tears running down Leo’s cheeks as he gripped the ottoman beneath him, he’d just started to squeal louder nearly moving into the territory of full-on screaming as he felt his hole finally starting to accommodate Sam’s obscene size before his face was shoved down into the ottoman as well muting his complaining and not a second too soon as a scream tore up through his body until his throat felt hoarse. Sam hadn’t even bothered to stop once he’d gotten his throbbing cock head inside of that angry red stretched hole, his hips continuing to push with their overwhelming force until he was balls deep inside Leo’s poor freshly deflowered ass, bulging out the boys stomach while letting him feel the crushing pressure on his prostate... Before Sam started thrusting without a care in the world grunting and groaning to himself as he pushed down harder on the back of Leo’s head, using his free hand to grasp on of his wrists using it as more leverage for slamming away at that deliciously tight hole; Sam’s fat swollen balls were crashing into Leo’s like wrecking balls sending jolts of further pain rocketing through his body while it was already near the point of over stimulation from a combination of everything else and that was exactly how Sam wanted it so with further deliberate roughness he adjusted his hips so he could slam his cock even deeper while beating and crushing his prostate in the most effective way possible, it barely took more than a few minutes of this before Leo’s was once again squealing instead of screaming his tight hole spasming around Sam’s fat cock as he came hard and while his load was minuscule compared to even Sam’s ropes of pre, it still drooled down the side of the ottoman. Even during that intense orgasm, Sam hadn’t slowed a bit keeping up the pressure on Leo it was quickly becoming more than clear that Sam was gonna try breaking him on the first go so it was no surprise that he didn’t let up for hours utterly refusing to cum while milking intense orgasms from Leo with barely a second’s gap between them, finally though after a brutally long session Sam was finally slamming himself up to the base to unload, Leo’s ass had been properly beaten and his nuts were incredibly sore from being battered By Sam’s but finally he was going limp around that hard cock as it flooded with thick seed until it was dribbling out around his cock and bloating up his belly just a bit, by the time Sam pulled out it was a gaping mess that drooled a river of cum down onto the floor.

Leo was finally ready to slip into unconsciousness after being used past his limits and then some but Sam wasn’t about to let it be that easy for him as he was rudely awakened with a messy cock slap while Sam re-positioned him as he sat himself down on the couch so he could watch TV again, his large hand moving down to grab the back of Leo’s head, tugging him up so that he was kissing the fat, cum covered cock head before starting to push him down not even sparing a thought for his experience before slamming his cock down Leo’s poor throat groaning delightedly at the way his gagging massaged the entire sensitive length while cleaning it off that leftover seed and while browsing TV Sam could get to roughly throatfucking the boy like he was a cheap toy, utterly ignoring the choking whines that came from him whenever he pulled his head up.

                                                                 -An hour later-

Lisa was almost dreading what she was going to come home to find, she’d gotten a ride with a coworker who luckily enough hadn’t left yet, while her car would be delivered in the next few days. She could only hope that Sam and Leo had gotten along well, it probably wasn’t the most responsible thing to let her fuck buddy watch her kid but the house wasn’t burned down so it couldn’t have gone that bad and she also now got to spend a week with Sam; Lisa was just wondering to herself where she’d get Leo to stay for the week as she walked in the door and was immediately assaulted with the familiar scent of Sam’s musk and the sounds of sloppy fucking. She didn’t even need to turn her head all the way to see Leo dressed up in some of her stolen clothes, his tail hole gaped and drooling cum with his head currently being used as a toy for Sam to slam down onto his cock, She was utterly stunned at the sight but Sam spoke up before too long
“Well seems you got home early, get those clothes off and get your ass down here so you can finish me off, Kids throat is too loose to get off when they’re half-conscious. But don’t you worry, I’ve got a lot of mother-daughter activities planned for the week!”
