you meet up with a trans girl to have sex. you go to her place and she ties you up with your legs spread, you figure that, she's trans, she respects your identity as a man, you don't have to worry about being taken advantage of like with cis men.
you've always been too dysphoric about your cunt to enjoy penetration there, which is why she agreed that she was only going to fuck your ass.
when she takes her girl cock out of her pants, she teases your asshole with the tip before, to your horror, slowly dragging it up and lining it up with your pussy, "beg me not to do this" she says. at first you thrash, but the ropes make it so you only accomplish wearing yourself out, then you start to beg. you've never done this before, you're dysphoric, you're a man, you don't want this. she just laughs and gets visibly harder to your words before cutting you off and thrusting inside your tight pussy
as shes pounding into you she reaches her hand under your binder and gropes your cow-like breasts, "i love girls like you, so stupid and naive, did you really think i wasn't gonna fuck your confused dyke pussy? Maybe once I'm done fucking a baby into you I'll take pity on you and use your slutty asshole too, I'd bet a girl like you would love that ~" you just shake your head while your cunt gets wetter and wetter from her words and you can't help but let out high pitched cries of pleasure
she reaches her hand down from your breasts to your clit, "what do you call this?" she asks as she rubs it in time with her brutal thrusts. you barely get out that it's your tdick, unable to keep the moans of pleasure out of your voice. she laughs again "i wonder if you're still going to call it that when i show you what a real dick can do; when I make you cum by rubbing your cute clitty while i breed you~"
you try to shake your head but it's already too late, she fucks into you harder and harder, hitting all of the good spots in your pussy that you didn't even know existed, and pretty soon your thighs start to shake and you can't even talk anymore as tears stream down your face. she tells you in a hushed voice, "cum for me baby~" and you do. you clench and squirt all over her cock as you scream in pleasure. She starts pounding into you as hard as possible, leaning over so her breasts are rubbing against yours and biting into your neck as she ruts into you like a dog. Soon you feel her thrust and still as her hot cum fills your pussy.
while she's still inside of you, she forces your mouth open and spits in it before petting your hair, "we're gonna keep going like this all night, until you accept what your girly cunt is really for ~"
