Her roommate.

Turning your head slightly, you can see Charlie peeking at you from around the corner. Narrowing her eyes, she walks over to you, wearing a tank top and short shorts, carrying half a six pack in her hands before blocking the your view of the television. "Evening Charlie," you smile. "How uh, how you holding up?"

Pursing her lips, she snaps off a beer and cracks it open with one hand. She takes a couple long swallows of it before responding. "You aren't fooling me. I know what you want." You raise an eyebrow at her and look around the room, checking if she's talking to someone else. She leans down and gets in your face. From her breath, you suspect that it might not be the first six pack she's gotten into today. "You just want to get in Terri's pants and then dump her. Just like all the other men I've dated."

Pushing her away with a couple of fingers on her shoulders, you defend yourself. "Look, I'm sorry the guys you've been with were all creeps, but I really like Terri okay? If it happens, it happens, but this is only our second...date, I guess. It's probably not gonna happen anytime soon, alright?"

Charlie eyes you suspiciously and sets the beers down on the coffee table. "No. No, it wont." she says, shoving you onto your back. You yelp out in surprise and suddenly find Charlie on the couch with you, fishing your cock out of your trousers. You try to fight her off, but she has a very tight and painful grip on you. "I'm not gonna let this thing call the shots for you. Terri doesn't deserve to get dicked around, just because you're horny. So what I'm gonna do, is get it out of you, so that Terri gets the real you, instead of the lying front you got right now, that's trying to get her to take her pants off."

There's a bit of a dilemma here. You could shout and try to fight her off, but all she would need to do is scream that you were trying to rape her and decimate your reputation and ruin your chances with Terri; or, you could let her do what she wants and hope that Terri doesn't show up suddenly when she's got your cock in her mouth. But the underlying issue with both of these options is that Charlie is drunk off her ass. It feels off for you to take advantage of her in her current state, and any court of law would take her side if she were to decry that she was unable to give consent because she was intoxicated.

So you're kind of fucked either way.
