She proposed that you'll fuck her while she will eat your cum out of Emma's pussy.

"You wanna fuck me while I'm eating your cum out of her?" she asks you.

"What?" You ask, caught off guard.

"You heard me."

"Oh, yeah. Fuck yeah!" You respond with enthusiasm.

She rolls over onto her stomach, planting her face between Emmas legs. Her ass points up into the sky, and you position yourself over her, your dick hovering over her asshole.

"Condom?" She asks. "To late, your maybe already pregnant. Why do you girls ask that allways after I came inside your cunts?" you ask her.

"Just a habit." She says.

"Are you sure? Because that was never my question to ask."

She turns her head, sticking her tongue out at you as she goes to work eating Emma's pussy and ass.Taking your cum into her warm, wet mouth.

"I'm going in." You say.

You push your dick into her ass, and she lets out a pained grunt.

"Are you ok?" You ask.

"Yeah, it's just... Different." She pants.

You slowly start to thrust in and out of her, and she grips onto Emmas legs hard.

"It feels good though, fuck yeah--don't hold back." She moans.

"I'm... I'm not."

"Just fuck my ass hard man!"

You smack her ass, the sound echoing through the lab."Don't yell at me, you're the one getting fucked."

"I don't care, fuck my ass."

You start to thrust in and out of her harder, she begins to moan loudly.

"Oh shit, yeah fuck my...." Her breathing becomes hard as she vocalizes any sound but its own.

You begin to feel your pace pick up.

"Yeah, don't stop." She pants.

Your heart is pounding as you feel something inside of you building up.

"I'm going to..." You grunt.

"Cum inside my... Fuck!" She cries.

You release deep inside of her ass, your orgasm causing you to grip the base of your cock and push deep into her.

You slowly pull out of her, before collapsing next to her. "Fuck... That was intense." She says. " I have an idea." She says position herself above the sleeping Emma pushing you cum out of her holes onto Emma's face.

"That's not nice," you say, on which she replies "Come on, she already looks like a fucked up bitch."
