18 M4F - Raped in the dorm bathroom [Fdom]

I sigh as I walk back to my co-ed residence hall after the last class of the day, exhausted from last night's frantic essay-writing. Fuck, I just want to pass out on my bed... At my floor, I exit the elevator and turn the corner to find a girl, maybe a year older than me, standing in the hallway, checking her phone. I've seen her around, but never had any interaction with her. I nod to her and politely try to slip past, our bodies touching for a split second before she turns and blocks my way.

"Um, excuse me," I say, a touch of uncertainty in my voice. She looks at me, a slight smile crossing her face as her eyes run over me, and then steps aside, letting me go through. I take about two steps past her before a hand covers my mouth and another wraps around my throat. I could tell that she was pretty athletic when I first saw her, and at 120 pounds, I didn't have much of a chance against a surprise attack. "Mmmmph!" I try to say something, but she kicks the back of my legs and drags me to the handicap bathroom, closing and locking the door and pushing me to the floor.

"What the fuck is -" I start to say something, but she cuts me off quickly, staring down at me.

"Don't say another word, or I'll run out of this bathroom, crying, telling everybody on the floor that you raped me." My mouth drops open, the beginnings of some sort of noise forming before she draws a finger across her throat, glaring at me. "Not. Another. Fucking. Word."

I was a little nervous posting this cause I don't think I have any writing skills, but here it is. 

With that cheerful intro, I hope it's clear the type of RP I want to do. As you may have guessed from my age and/or subject matter, I'm starting college this year, and thought it might be interesting to fantasize about something rarer than the usual noncon. This is my first post where I actually have a scenario, and I'd appreciate feedback if you're willing to take the time to read it. 

I'm aware I wrote in the other character's actions, but that's only for the intro. I hate when people write for me too. I intentionally didn't describe the girl so you can make her however you'd like.

I'm about 5'7", medium length dark hair, brown eyes, glasses, slim, kind of nerdy, quiet, shy. My limits are kids and bodily fluids not normally involved with sex.
