It takes a while before Scar approaches him. By this point, Grian has basically accepted his place in the pack. He's well-fed and protected, and kept warm every night even after he's abandoned his clothes. Sleeping in a pile of furry bodies does well to trap in heat. He felt embarrassed before at walking around naked all the time so he kept his clothes, but eventually it becomes too much of a hassle to take them off every time a wolf wants to fuck him, so he just leaves them somewhere.
And, of course, his cunt is constantly wet and dripping from both his own slick and cum. He never goes long without getting fucked, and he's come to reallllly like the feeling of being filled up and knotted. There's a river he'll bathe in on occasion but he's never clean for long before he's being pinned by a wolf again, so he only does it if he really feels like he needs to.
The day was like any other when Scar finally came up to him. Grian doesn't know what he was waiting for, if anything, but one day while Grian is sleeping in a pile of wolves, he wakes to Scar watching him. A shudder goes down his spine at Scar's gaze. Scar motions for Grian to follow him, and he quickly scrambles up to do just that. As he follows Scar, his head spins. What does he want? Is he finally going to fuck him? This is the most direct attention he's gotten from Scar since he joined the pack.
He takes him out of the cave, somewhere into the forest. Grian's a little worried that someone's going to see them, or worse, that Scar's decided he's not a good fit for the pack and is going to kill him. But a glance down at Scar's dick reveals that he's hard and leaking precum. Immediately Grian is clenching and leaking slick at the thought of him finally fucking him, and he's a little worried because Scar is bigger than the wolves he's been fucking. Is he going to fit?
Still, despite his nervousness, when Scar stops in a hidden area and turns to Grian with an eyebrow raised, Grian wastes no time in presenting himself, shuddering as he feels his cunt leaking slick down his legs. Scar comes forward, mounting him with his front paws pinning him down and cock going right to his cunt.
Slowly, inch by inch, Scar works him open. He thrusts a few inches in before pulling out and thrusting in again, a bit more each time, until he's nestled in his cunt. Mercifully, he gives Grian some time to adjust. And then he's fucking into him, hind paws firmly planted on the ground to give him the leverage, and all Grian can do is take it. Each hard thrust into his cunt, never giving him a moment of reprieve as pleasure is forced into him with every grind against his g-spot.
And then he starts to feel the knot building, grinding against his hole, and he can't help but try and work back against it, desperate to get it in him. He feels so full but he knows he could be even more full. And then it pops in and he comes at the fullness, especially as Scar starts to come inside him. It fills him up with nowhere else to go with the knot plugging him.
Scar settles beside him, carefully maneuvering him until they can lie beside each other without pulling on the knot. Scar kisses him, and Grian practically moans into it, trying to press himself closer. When they part, Scar starts to preen his wings - having seen Grian do it himself - and Grian relaxes into him.
It's a few days later, when Grian is stuck on Scar's knot another time after Scar fucked him, that Scar finally tells him why he decided to keep Grian, and why he waited until earlier to fuck him. He tells him that Grian is pregnant, which sends a jolt down Grian's spine. He hadn't even realized that was possible. He gets a little worried, too - he's a hybrid, does that mean the pups will be hybrids too? But Scar reassures him that the pups will just be wolves.
He hopes the pups are Scar's, but Scar happily informs him that is not the case. In fact, he'd specifically waited to ensure the wolves had bred him before he fucked Grian himself. He wanted to make sure Grian had accepted his place in the pack as their breeding bitch. Grian clenches around the cock in him at those words, and feels another spurt of cum fill him up.
Grian rubs a hand against his stomach, marveling a little at the idea that he's been filled with pups. He thought his stomach rounding out was just from him eating a lot - the wolves were very efficient hunters, and he'd gotten good at foraging as well - and being filled with so much cum, but to find out that he's pregnant...He is relieved that he won't have to raise any actual people, that it'll just be some more wolves. He had noticed that none of the wolves in the pack were capable of birthing pups, but had never really thought about what that might mean for him.
It's a couple months later that the pups are born. His stomach expanded rather rapidly, and he had to stay in the cave more often. The wolves all became far more protective of him, often grooming him and still fucking him. Which Grian appreciated, because just the thought of being pregnant, of becoming the pack's breeding bitch, often made him horny.
The birth goes smoothly, which he's grateful for. And after, he curls around his 3 pups. 2 are latched onto his tits while the other cries. His tits have gotten a bit bigger during the pregnancy, but Grian doesn't mind. It just means he's able to feed his pups better. It'll be a struggle to feed the 3 pups, but Grian is determined to be able to watch them all grow big and strong. This is his purpose, he's here to help the pack grow.
He stays in the cave to keep an eye on the pups. The wolves give him a break for a few days, but soon enough they're back to fucking him. Scar does, too, and Grian hopes the next pups are his. There's a few times where one of his pups will mistake his clit for another teat, often while he's dozing off. One will do a little exploring and finds his clit and clamps their little teeth onto it, and Grian very quickly wakes up. It takes him a moment to even process what's happened, and then he feels the pup suckling on his clit, searching for milk it's not going to find, and he nearly doubles over from the unexpected pleasure. (Which Scar always finds absolutely hilarious)
He can live out his days being constantly horny and filled with cum as the pack's little breeding thing. If he's horny, he can present himself and within seconds a wolf will be mounting him. The wolves used to bite and snap at each other, aggressive, but now they can take that out on Grian. He helps keep the peace by being someone the wolves can fuck. He can be sooo happy and full with a big belly full of puppies :3
He doesn't have to worry about his old life anymore, he can just live in the forest where he's always full, easily able to get fucked at a moment's notice whenever he wants, and he's got Scar who by this point dotes on him and makes sure he's nice and comfy. And bred <3
Another I'm not super crazy on, but it can definitely be fun! Reducing someone to be nothing more than something to breed and fuck, to milk...I looooove breeding kink stuff so honestly it kinda scratches that itch pretty nicely lol
