You shove him off of you just in time

You plant your hands against his chest and you give him a hard shove and then roll your body in the opposite direction. He's not prepared for the movement, and he slides out of you and tumbles down half off the couch. "FUCK!" he gets out just before he cums, spraying his seed over the couch. A few warm pulses splash against your left hip.

He stares down at his cock, then at you. "You fucking bitch!" he hisses.

You rise to your feet, glaring at him, teeth grit together in frustration. You've managed to avoid him cumming in you, but you're not out of the woods yet. He's angry, for one, and there's still a good chance you could get pregnant from his precum for another, but for the first time since the movie started, you feel like you're in control again. And you're angry. Holy fuck but you're angry!

"Hey Isaac," you say, "Protip: calling me a whore, and a slut, and a bitch? That's a great way to completely end any interest I might have had in having sex with you. You KNOW me. You should fucking know better than to pull that kind of bullshit. I know your brain's probably been warped by all the porn you watch, but the fact that I'm ready to be a woman for the rest of my life AND I have a sex drive AND I was willing to make all that happen with you doesn't make me a whore. I am not your whore, and I never will be, got it? Try again, this time with less 'complete fucking asshole'."
