It's another thing Grian had posted about on her tumblr a lot. Post after post about wanting to be fucked and knotted by a dog. It was always one of those things that she never expected to actually happen. She'd been saving up for a knotted dildo when Scar broke into her house.
It comes as a shock to her when Scar comes home one day with a large Irish Wolfhound in tow. Cheerfully, he explains that he's just helping someone out. They needed a dogsitter to watch their dog for a few days, so Scar had volunteered. He apologizes for not asking sooner, but surely Grian doesn't mind, right?
She's a little apprehensive, especially with the way the dog looks at her, but eventually agrees. Not that she had much of a choice, really, but at least Scar seemed apologetic for offering to do this without talking to her about it.
The first night is fine. The dog sleeps on the couch, while Grian sleeps on her bed tucked into Scar's embrace as usual.
It's the first full day that problems start to arise.
By this point, Grian is no longer working or going to school. Scar had told her there was no point to, she can just stay at home! Which means now that she's alone with the dog as Scar goes to class. He won't be back until later, so she has to entertain the dog by herself until then.
The dog is friendly, at least. They were given a few dog toys, so she plays a few rounds of fetch with him. He enjoys pets, too, so she makes sure to give him a lot of attention. And belly rubs.
The moment Grian realizes the dog isn't neutered, she tries not to think about it. It doesn't help that, for once, Scar's even taken off her chastity belt before he left. She can't remember the last time he did that. He also told her there weren't any rules she needed to follow. All of this after days of not fucking her...It caught her off-guard. She tries not to look too into it, but...He's seen everything she ever posted (and continues to post) on her Tumblr. So surely he knows how she feels about...certain animals.
Eventually, it gets too much. She can feel herself dripping from both her thoughts and from being so close to a large dog. She's desperate to be fucked, desperate to do something about the need pulsing through her. And she's finally able to, with the chastity belt off and no rules.
But she also doesn't want to force the dog to do anything, much as she longs to be knotted. So Grian goes into her room and closes the door before quickly throwing her pants and panties off. She wishes she'd managed to get the knotted dildo, but for now a vibrator will do. She grinds her cunt against it, getting close to coming before long while thinking about the dog fucking her.
She hears movement and for a moment thinks Scar has come home early, but a glance at the door shows the dog nudging it open and walking in. Panic spikes through her - she must not have closed the door all the way. Before she can get up, the dog's nose is shoving its way between her legs. She yelps and tries to push the dog's head away, and then he's licking her.
Grian gasps and stops her efforts to push the dog away as the feeling rushes through her. She's been denied for so long, Scar not having fucked her once in days, so to feel the pleasure she's craved...and from a dog, no less, has her coming on the dog's tongue very quickly. She takes a moment to catch her breath, which the dog mercifully gives her. He's looking up at her, panting, tongue poking out of his mouth, and a quick glance down shows his dick poking out of the sheath.
Though she's finally managed to come, it's not enough. She needs more. And, well...if she just presents herself, and if the dog mounts her...It's not like she's forcing him to, right? He did it on his own, after all. She's trying so hard to justify herself as she rolls over until her hands are on the bed and her legs on the ground, presenting herself to the dog who doesn't spare a single second as he mounts her.
Grian gasps as he tries to find her hole, thrusting a few times and smearing pre-cum on her back, before he finally manages to find her cunt. With how wet Grian is, he sinks in immediately and she moans, clenching around his length. Wasting no time, he starts to fuck her, fast and hard thrusts while she's unable to do anything but lay there and take it. When she comes, the knot that had been pounding against her hole finally pops in from how loose and wet she gets.
She's so focused on the dog knotting her and filling her up with his cum that she doesn't realize the front door's opened, or that there's footsteps coming down the hall. She doesn't realize that Scar is leaning against the doorway, watching her. At least, not until he whistles and her head moves over to look, eyes wide.
The dog is excited to see Scar and tries to move over to him, but the knot is still stuck so he doesn't accomplish anything aside from making Grian whine. She tries to splutter out some excuse, some apology, but Scar waves her off. He's glad they did this! It's the whole reason he offered to dogsit in the first place. He's sad to have missed it, but did he make her feel good? She's stretched out around the knot and pumped full of cum.
Scar comes over to her and cups her face and she can't help but close her eyes as he runs a hand through her hair. He pulls away and she whines, but he quickly soothes her, saying he just wants to get some pictures. Gotta memorialize this moment somehow! He gets a few pictures of the knot buried in her cunt and even a video of the way his balls pulse as he shoots even more cum into her.
"He's really filling you up, huh?" Grian can't even manage any words as Scar rubs her clit. "Maybe he'll be able to finally knock you up. We'll have him for a couple of more days still, so I suppose there's only one way to find out!"
She whimpers as he goes on to say that he knew she'd look so pretty while under a big dog. He'll skip his classes just to watch her take the dog all day for as long as they can. When the knot finally goes down and the dog pulls away, he gets a video of her hole gaping and dripping with cum. Later, Grian finds that video on Scar's Tumblr with the caption "knotted and bred"
The dog continues to fuck her in the remaining days before Scar has to return him. Scar gets plenty of videos of the dog fucking her, the way he thrusts, feral and uncaring of her pleasure and only seeking his own. He makes sure to get shots of Grian's face, the way her eyes roll back with each thrust, or the point where the two connect, especially as the dog knots her. He gets a few of the little tummy bulge she gets from the cock, too.
Grian feels herself getting addicted to the dog's cock and the cum as it fills her cunt, moaning with each spurt. The one fantasy that she thought would never come true, but here she is, forced to become a dog's bitch. He fucks her mouth, too, and knots her there. And her ass. By the time they have to return the dog, Grian is well and thoroughly used by the dog. She can't help but feel mournful as Scar takes the dog away. At least Scar tells her that someday they'll go out and buy one for her! A nice little present for her <3 because he loves her sooooo much. She can't wait.
Going to start this blog off with some lovely tumblr mutuals au. It's really only mentioned in the first fic (which you can find here) but later fics will go all in on the misgendering/forced detransitioning.
It's a bit of a slow process. Grian puts up a fight at first - he's a man. Not a woman. Not a girl. Sure, he's posted some stuff like that on his Tumblr, but...it wasn't meant to actually come true. It was supposed to stay as a fantasy. A lot of what he posted was. It was all just something for him to get off to after a long day.
And now Scar, his longtime friend and apparently the guy behind his favorite Tumblr account (that he's been flirting with for months), has found out who he is and broken into his house to fuck him in the middle of the night. And he just...doesn't really leave.
I mean, sure, he goes to classes and work, but he doesn't go back to his own place after. He goes to Grian's and stays with him and often fucks him. And honestly Grian kind of likes the constant sex. He's been on T for some time now and it's made his libido skyrocket, and it was already pretty high. It's part of why he'd made that Tumblr account in the first place. So he likes the constant attention he gets from Scar, he just...
He wishes he didn't have to deal with the constant misgendering. The constant insistence that Scar can turn him back into a woman, the way she was always supposed to be. That he can "fix" Grian. Every time he says it, he comments on just how wet it makes Grian. And every time, Grian hates himself a little more for it.
Because it does. He knows it does. It's what had drawn him to the kink in the first place. At first he'd been disgusted, but something kept drawing him to it. He scrolled through blogs and tags and soon realized it made him dripping wet much faster than a lot of kinks. So he'd experimented a little. Made some posts about it. Jerked off to asks and messages of people misgendering him. And then he'd come and go on with his life.
He didn't do the same thing others did sometimes. Didn't make posts begging for notes to do something, or stop taking his T for any period of time. He'd worked hard to be able to even get the stuff, he wasn't going to stop taking it just because of a kink. It was just something to think about for a bit and then move on. Until he went back to it the next day, at least.
Things come to a head though when Scar fucks him and then stops right as Grian's about to come. He does that a few times, actually, and just when Grian feels like he's gonna smack some sense into Scar, he tells Grian he's only going to let her come if she admits she's a girl. Otherwise, he'll just keep edging her.
Grian's mouth drops open. There's no way he's serious, right? Scar knows he's a man! He's one of the first people Grian came out to because he knew he could trust him. And sure, he clearly knew about the kink, but this...
Grian knows it's not just a kink for him. He truly, genuinely believes in forcing him to detransition. He has this entire time. Grian had played into it a little at the start, but he realizes now with startling clarity that it was always real to Scar.
He doesn't think he can get out of this.
Maybe she - he - could fake it, but Scar would know. He'd always know. This was his goal from the start, and he's determined to get it. He tells him often that he's going to breed her (another thing that makes him panic, but he tries to ignore it) and make her carry his children, turn her into the woman she was always supposed to be.
There's no escaping this. Not unless he just denies himself an orgasm, possibly forever.
And, horribly, he really wants to come.
He can feel it building, but Scar always stops before it crashes over. It leaves him frustrated, writhing on the bed and desperate for more friction that doesn't come in time. But if he gives in, if he lets Scar turn her back into a girl...If she can just come...
He's grinding into her again, and Grian can feel the pleasure building and building. So before Scar can back off and let the wave pass without carrying her with it, she gasps out: "I'm a girl! Fuck, please Scar, let me come, I'm a girl, pleaaaaase please please -"
Scar groans and continues fucking her, and finally, finally, she comes. It's unlike any orgasm she's ever felt before. She swears she blacks out for a moment and comes to later to Scar having slipped out of her, a plug nestled in her cunt in his place. She knows she's filled with his cum and relaxes a little at the thought.
She's nothing more than a pile of jelly as Scar scoops her up and carries her to the bathroom, praising her the whole way. This feels nice. She likes Scar's attention, likes him telling her she did good. She wants that more often.
And she'll get it. Scar's soooo proud of her now that she's finally accepted who she was always supposed to be. Doesn't it feel nice? This is what was always supposed to happen. He's soooo glad she's finally embraced it, and he'll make sure she feels soooooo good at all times.
