You make your way back to the living room, feeling your pumped legs causing you to gently sway each brawny thigh over the other. You silently wished it was a more pronounced swagger like you used to be forced to do, but any feeling of ‘big’ would do. You plod up the stairs, the stairwell splitting into two paths, to the right and to the left. The master bedroom, your room, and another bedroom, your boyfriend, Ty’s, were to the right, the rest were on the left side.
Your lupine ears pick up the sound of a shower running from the left side. You pause in your step, using your sensitive hearing to eavesdrop. You can hear the sound of deep breaths punctuating the drizzle of water.
“Gruungh,” a deep, bass-laden moan rings through the walls. “Deeper, Andy,” it huffed. Tristan Seouk. He was a massive water deer, and one of your best friends. Or at least, at times he could be. Ever since you’ve shrunk down, and he’s continued to beef up into a humongous lifter that would rival your old competition weight of 660 pounds lean, he’s treated you a little differently. You wouldn’t say he bullied you, but you could definitely tell there was a little more bite to his words when he was around you, a smug sense of superiority. ‘Ungh, pass the salt will ya, skinny?’ he said at the dinner table. ‘Watch it, runt, big MAN coming through,’ he grunted while trying to pass you in the hall. ‘Sorry, might have stretched it a little, shorty,’ he remarked when he passed the cock-chiller to you. He’d gotten pretty huge before, sporting a massive abgut along with his muscles, but lately, ever since spring break of last year, he’s been leaning down. Hell, if he really went for it, he could have a permanent 6-pack if he tried, instead of the ‘temporary 8-pack’ he gets when he sucks in his tummy.
“Unnngh!” an even deeper voice boomed from the shower. That had to be Andy McNeese Jr. He was a kangaroo and pretty much the biggest guy you’ve ever seen beside yourself at your biggest. The kangaroo was an insane 800 pounds, and unlike his boyfriend, Tristan, it was all dense, purely shredded muscle, not an ounce of fat on him. He used to be relatively small, the build of a runner and you’ll admit he used to have one of the most fuckable asses on campus. But all that changed last year. Andy hit a growth spurt like you’ve never seen. The roo pumped himself with so many government-funded superdrugs thanks to his connections to the CIA and army through his dad and stepfather, it wasn’t even fair. Now he stretched shirts to their limits, every one a midriff, exposing a dense jungle of reddish pubic fur. Those shorts of his didn’t fare any better, possibly worse. Being a huge boomer, Andy’s legs were beyond insane, they could rival your chest!
Not only was Andy’s physical development beyond comprehension, but his demeanour had changed completely as well. He used to act way younger than his age, an annoying kid that wouldn’t be out of place in high school, what with how whiny and how much he used to complain about everything. The bigger Andy got, the more aloof, the more... frustratingly sexy, he got. There was still a little mischief in his gaze, he’d still flash a wink to you when he caught you staring at him before blasting his bis for you. He went from a guy who would gab constantly, to an alpha male who could get what he wanted with just a little grunt. Gods... you were getting a little stiff just thinking about it...
You make your way to your room, passing Ty’s along the way. You peer in to see the slight mess the huge pitbull left in there. A humongous desk with his laptop closed, his bed disheveled and unmade. Last night the big pup got listless and came into your room for a little ‘fun.’ Heh, you could see the pre-cum stain settling into his sheets. You sigh, realizing that even for Ty it was a bit unnatural. Sure he was well over 600 pounds, every bit as big as Tristan, but his libido had never been this high before. You sometimes wonder if it’s his newfound love for topping you that did it. Who knows. You peer at his shelf and groan, looking at all the teen bodybuilding trophies he’s won back in his heyday. Damn, you had a couple yourself, but you weren’t nearly as accomplished as the pitbull.
You finally make your way to your room. You’re immediately met with the smell of musk, wet dog and fresh linens, an odd combo to be sure, but one that was frequent with how much Ty spends in your room and how spartan your room was. Other than the bed, everything was in order, just how you liked it – everything in its place, everything predictable.
Lying on your oversized bed with his enormous, globular ass up, was your boyfriend Ty. Every time you see him, your heart skips a beat. The big boy was always there for you. His cute smile never failed to melt you. You begin to drool in your mouth as you stare at his exposed rump. Gods, it was so rare these days for him to let you top him, even if your cock was more than half again as big as his 10” rod. His back was so vast, so meaty, mounds of rock hard muscle encased in a light layer of fat, skin and tanned fur.
“Oooooh,” the big beast moans. His eyes flutter for a moment but remain shut. He sniffs the air and smiles. “Hi, baby,” he coos, his deep voice rumbling to your core. He hugs the pillow underneath his head and squeezes his arms. At the same time, he squeezes his rump, his tail wagging slightly. “I’m sooooo horny,” he grumbles, slowly grinding into your bedspread. Woof, talk about morning wood. The way he lifted his tail told all.
You growl lowly and you can’t get your shorts off fast enough. Ty barely let you top these days, so you jumped at any opportunity you could get. You climb on top of the bigger beast, your 16” prick rock hard as you hotdog it between his massive glutes. The dog pants into the pillow and bounces his ass around your steely rod. You growl, sneering menacingly as you force your way into his ass.
Gods, Ty’s so tight! Even with his bigger size, the sheer development of his ass muscles made it a trial and tribulation, one you gladly accepted. The dog pants happily, his tongue flopping out as you push inch after inch into him. The way he bounced on the bed in time with your thrusts made you go in deeper. Your eyes roll back with delight at the sheer pressure crushing your huge cock.
“Ohhh, Tyyyy!” you moan, picking up the pace.
“Awooo, harder, babe!” Ty whines. He bucks violently, wanting more of you. Ohhh, you’ll give it to him. You push up off him and then powerslam your pelvis right into his ass, a sonic clap ringing through the air as you do it over and over again. “MORE!” Ty begs, “HARDER!”
“You got it, bitch,” you snarl. Your hands wrap around his gargantuan ribs and you piston into him with so much force you’d kill a lesser man. Ty lets out a satisfied yelp and you go even harder. “Fuck yeah,” you roar. Oh man, this is how it should be! You felt 10 feet tall when Ty let you fuck him, and gods did it ever feel good.
“Harder, faster, c’mon, babe,” Ty whines. Your revelry is cut short when you feel his arm reach back and he tugs at you. Hard. “HARDER,” he snarls. You buck as fast and as strong as you can. “Hnnngh, c’mooon,” he whimpers in response. “Unngh, uuuugh! C’mon, Conner, fuck me harder!”
“I’m cum... cumming,” you choke in your throat as you lose control. You spasm and lose control of your rhythm. You were too lost in your own pleasure to question who the fuck this ‘Conner’ was. You nut inside the behemoth of a pitbull for a good minute before you’re reduced to a dribble.
Spent, you pull out, gasping from the intense fucking. Ty rolls over onto his back, the two of you staring into each others eyes as his eyelid flutter awake, still bleary.
“Hi, baby,” Ty coos.
“Hi,” you pant, still too spent after the fuck. Before you can ask him who ‘Conner’ was, he pulls you into a hug. You feel his massively thick length push against your leg as you lie on top of him. The big beast groans as he reaches around you to play with his shaft. He begins to pant lowly as he strokes at himself, closing his eyes as he pleasures himself.
“Arooo,” he howls as his magnificent, coconut-sized nuts pull up and gush a geyser of white-hot cum all over your back. He goes on for over 3 minutes, continuing to blow inordinate amounts of seed out of his length thanks to his well-developed balls. All you could feel in that moment... was revulsion.
You feel the tears welling in the corner of your eyes. You were pathetic, you couldn’t give your boyfriend an orgasm while fucking him. He brazenly finished himself off without even trying to get you to finish him off, as if to say it wasn’t even worth the effort of trying. And to top it all off... he called for some guy named ‘Conner.’
“Aaah,” Ty gasped happily as he slumped in his posture, thoroughly spent. “Woof, that felt good, thanks, Georgie,” he says softly, a gentle smile on his handsome muzzle. He’d fucked you at least three times last night, and to top it off he had multiple wet dreams that woke you up in the middle of the night too. There was no stopping Ty’s new libido. And to make things worse...
“Oof, my elbows and knees ache,” Ty whined.
“Again?” you murmur. “You should get it checked out, maybe your weight is taking a toll on your joints.” You say it, but you have a deeper suspicion... his joints in pain, his increased libido to insane levels, you worry... that Ty might be going through a growth spurt soon, leaving you further in the dust...
You roll off your big boyfriend and rest your head on his meaty shoulder. The pit’s already snoring and soon you join him, enveloped by his cum, heat and musk...
