"You don't even have to do much. Just a little, please?"
Is what Charlie's friend Brock said to him just twenty minutes ago. The wolf shifter, currently in his human form, had approached Charlie with a strange look to his face. He said, plainly, that he'd like to call in a favor that Charlie owed him from a little while back. Charlie took it in stride; he knew that, logically, since he owed the guy about 500 bucks, Brock was allowed to ask for something else in exchange. He's cool with that. So he shrugged and smiled and said, "That's cool. What is it?"
And Brock, who still has a strange look to his dark, smothering eyes, said, "I need you to suck me off."
Charlie, taken aback, attempted to argue at first, but Brock had been calm and firm in his request. Eventually Charlie, after minutes of self debate, decided it would be fine. He's sucked cock before, and he'd be lying if he said that Brock, with his broad, muscled form and handsome face, wasn't attractive. Sure it was a little weird, giving his long time friend a blowjob, but he did owe him a lot of money... So he gave in and agreed. Maybe it'd be fun?
Twenty minutes later and he's on the floor, his legs folded beneath him, as he stares down the front of Brock's jeans. The bigger man unbuckles his pants, and as he slowly works the zipper down, Charlie swallows down his nerves. Brock's cock, large and dark and hard as a rock, springs out of his pants just moments later, almost hitting Charlie in the face. As it's so close to him, Charlie can see all the details of Brock's thick, veiny cock, as well as the precum dripping from the slit. It's long and so, so thick, and suddenly Charlie feels his mouth watering.
There's no way he can fit all of that in his mouth. But for some reason, he really wants to try.
Without a word, Charlie leans in, presses his lips to the tip of Brock's dick. Brock gives a soft inhale, staying still as Charlie does it again. He leads a trail of kisses up and down his shaft, and as he comes back to the tip he inhales and takes the head into his mouth. Brock's cock twitches in his mouth, and the man gives a soft groan, his hips subtly pressing forward. Charlie is fine with it, finds he enjoys it more than he thought he would.
Charlie, despite his earlier trepidation, finds it fun. Giving head is always an enjoyable experience for him, and this time is no different, baring the weird fact that it's his best friend. He swipes his tongue around the head, sucks at it a bit before pulling off to lick long stripes up Brock's length. He lets his salivating mouth get Brock's cock nice and wet, then proceeds to suck several inches into his mouth all at once. Brock almost howls, one of his big hands coming to rest atop Charlie's head as the smaller man goes to town on his dick.
The sound of Charlie sucking dick is loud in the otherwise silent room. Brock's cock is huge, and so Charlie has to do a lot of work to keep up with it, sucking wetly as he tries to force it into his mouth. After a few minutes of rigorous head bobbing, Charlie sucks in a deep breath, and swallows around Brock's cock, letting it slide slowly down his throat. He gags, just a little, but if there's anything he knows he's good at, it's deepthroating cock. He fits a few inches down, swallowing all around it as he begins to bob his head once again.
Brock, now unable to stay still, holds Charlie's head with both hands. He's not leading him, just simply holding on to him as he lets Charlie do his work. Charlie braces his hands on Brock's thighs, using it as leverage to fuck his throat open on Brock's thick length. Every two minutes or so he pulls off a bit, sucks at the head while he regains his breath, then dives back in, taking in a few more inches every time. He's egged on by the soft grunts and groans coming out of Brock, the sounds going right to his cunt.
It's good. It's very good. Charlie didn't intend to get into this much, but the longer he does it, the wetter his boxers become, soaked by the slick gushing out of him. He swallows and sucks, squirming a bit in place as the arousal quickly becomes a problem. It gets worse as Brock's fingers tighten in his hair, carefully but firmly pulling his face forward as his hips do the same. Fuck, that's so hot. Charlie feels delirious.
That's when the change happens. Charlie, having been privy to Brock's secret since they were younger, knows the telltale signs of Brock shifting into his wolf-like form; the sound of joints cracking, the slowly deepening growl that comes from Brock's throat. Charlie's eyes widen, and he instinctively tries to pull back, but is held firmly in place by Brock's superior strength. Charlie is forced to be still as Brock grows in front of him, his body shifting into a familiar half-wolf, half-human form. Everything about Brock grows, from his limbs to his torso, to his cock, still in Charlie's throat.
Charlie feels it all, feels the way Brock's cock morphs into a canine's, the thick prick slowly thickening to twice its normal size. It bulges obscenely in his throat, a scene that he's sure he'd be both awed and embarrassed to see. The cock fills him so well that he has no chance of breathing, and is stuck to the mercy of his shifter friend.
Brock, once done transforming, pulls at Charlie's hair with a low growl. He throws his hips forward, pulling Charlie towards him as he fucks his cock deeper into Charlie's stuffed throat. Charlie gives a choked whimper, his hands pressing at Brock's thighs as if begging him to stop. But Brock, lost to the pleasure, doesn't listen. He happily fucks away at Charlie's throat, giving pleased growls and groans as he uses the man as a cocksleeve. Charlie's lungs are burning, as he's only able to take in an errant breath when Brock pulls out. Soon, though, his rhythm becomes so fast that even that doesn't happen, Brock too busy grinding into his face as he starts approaching his limit.
Charlie can't take it. Brock's thick, heavy balls are slapping his chin, and his knot, growing thicker by the second, presses against his lips with each thrust. He didn't sign up for this. He didn't expect Brock to shift in the middle of a blowjob. But now that he's here, he feels his frustration mounting as a crazy spark of arousal, his pussy dripping endlessly as he endures the abuse. He feels used, like some kind of human toy. His swollen clit throbs, pussy clenching over nothing. His thoughts become a mantra of "fuck, fuck, more, more."
The knot slips into his mouth, dragging in and out with every harsh, fast thrust. Part of him is worried, concerned about what will happen if that knot stays in his mouth. His lungs are already screaming for air— it'd be bad if he were connected by a knot for who knows how long. But the other part of him is begging for release, and that part wins out. The knot catches. Brock growls. Charlie whimpers, pussy pulsating as he starts to come. Brock isn't far behind, grinding his hips into Charlie's face as his thick load spurts right down his friend's tight throat.
Charlie swallows, and swallows. He can't do much else. He's shuddering, almost choking over the cum. He can't breathe. He can't move. His orgasm grows and grows, electricity shooting up his spine as the reality of the situation makes him even hotter. He's been knotted, and is fully at the mercy of his shifter friend. He can't help but come again at that thought.
Predictably, Charlie ends up in a precarious situation. He needs air, yet the knot holds the thick wolf cock down his throat, stopping him from taking a full breath. Eventually he starts to feel light headed, shaking desperately as he slams his hands against Brock's thighs as a beg to be released. There's nothing that can be done, though. He starts to pass out right as Brock's knot starts to deflate, blearily going in and out of consciousness as the werewolf lays him down on the floor.
Charlie wakes a few minutes later. He gives a confused moan, whining as he rolls his head and opens his eyes. Brock is between his legs, cock pressed deep into Charlie's soaking wet cunt. Charlie groans as he realizes, shaking his head as a shiver goes through his body. Fuck, that's so much. That wolf cock is so big and thick and it's stretching his pussy apart. "No...!" He whines out, drool and cum dripping down his chin. "We... didn't agree to this...!"
Brock doesn't speak, just growls. His massive hands are holding Charlie's waist, holding him in place as he pounds Charlie's cunt. His cock drags in and out of that tight cunt over and over again, and Charlie, overstimulated and confused, can't help but whimper as his walls cling to Brock's length. It feels good. This shouldn't be happening.
It goes on for a while. Charlie finds himself coming again as Brock grinds into his cunt, unable to resist the stimulation of all his sensitive spots inside. Brock fucks him hard, slams his cock past his cervix and into his little womb. He seems to enjoy it massively, groaning and grunting like crazy as he squeezes Charlie's soft waist. Charlie gives a high pitched whine, fingers scrambling along the hardwood floors as he tries to cope with the stimulation being forced upon him. It's so good, it's too much. He's drooling and crying, thoughts turning to mush.
Brock's knot swells again before long. He presses his body over Charlie's, his hips flush against the human's as he pushes his knot right inside. It locks the two of them together, Brock still thrusting his hips forward to fuck as much of his cock as he can into his womb. Charlie, sobbing, cries out desperately as he comes again. His overstimulated nerves are screaming at him, but even still, Brock keeps fucking pleasure into his cunt.
With a possessive growl, Brock hits orgasm as well, holding Charlie close to him as his throbbing cock blows its load. Every hot, thick spurt goes right into Charlie's womb, filling him up until a bulge grows in his stomach. Charlie feels every bit of it, can't help but whine and cry as it lengthens his orgasm. Crushed beneath Brock's large body, Charlie can't run away, can't do much else than take it. He's being filled. Stuffed. Bred.
The next ten minutes are spent lying on the floor, Charlie trying to catch his breath and calm his overstimulated nerves. Brock's hips roll every few minutes, just enjoying the tight heat of Charlie's pussy and womb for as long as he can. Soon, the knot goes down enough for Brock to pull out— when he does, a bit of extra cum leaks out, getting all over the floor and making a sticky mess of Charlie's inner thighs.
Charlie blearily looks up at Brock. His friend's cock is half hard, sticky and covered in cum. Charlie eyes it wearily.
"You know... I thought it was only supposed to be a blowjob."
Brock's fluffy ears twitch.
Charlie sighs. "Asshole."
Charlie makes to get up, turning around onto his hands and knees and attempting to stand up. Unfortunately, that was the wrong thing to do, as right afterwards he feels Brock's huge body draping over his back, his now fully erect cock pressing in at his cunt once again.
"Fuck!" Charlie cries out, scratching at the floor as cock pierces his swollen pussy. "No! Not again...!"
Brock immediately starts jackhammering away at Charlie's cunt, not giving the smaller man any chance to get away. Brock fucks him, and fucks him, hips moving at a desperate pace as he chases pleasure in his human friend's tight body. Charlie is sobbing, hips twitching away from Brock's but unable to escape the relentless pounding.
In the next hour, Brock manages to knot Charlie two more times, filling his womb with so much cum that he swells like he's several months pregnant. Charlie is forced to take all of it, knowing that there's nothing he can do to stop his much stronger friend from taking advantage of his soft little cunt. He's covered in sweat, tears, and cum by the time it ends, left a shivering mess on the floor as Brock pulls out for the last time.
Charlie falls asleep right there on the floor. When he wakes, a blanket has been thrown over him, and Brock, having re-shifted back into human form, is at his side. Charlie swallows, wetting his dry mouth and throat, before saying, hoarsely, "You ass."
"Sorry man, I couldn't help myself." Brock shrugs and smiles sheepishly, looking down into Charlie's tired face. "But hey, consider us even now."
Charlie gives a sideways frown, and Brock laughs.
"You were a great lay. We should do this again." Then his voice gets deep. "I'd love to fuck your pretty little cunt until you're full of my pups."
A shiver goes down Charlie's spine. He looks at his friend, at the dark, hungry look on his face, and sighs. He wants to say no. He wants to be mad at his friend for going overboard and doing something he never intended to do.
But instead his cunt quivers and he ends up smiling instead. "Could be fun."
Brock grins.
