Her ass

"The back" I say with decision.

Marie sits on the bed, and her rock hard cock swings like a pole. Monica swiftly gets on top of her, and kisses her hard. It turns me on to see my girlfriend kissing her lover, our bull, so passionately. She grabs Marie's dick and directs it towards her pussy. I can see it slide in quite easily, given she's completely soaking in her juices and still some of Marie's semen. She grinds her hips, taking her huge cock whole, moaning. She leans forward and Marie grabs her ass and spread her butt cheeks, so I have an easier way in.

I press my dick against her asshole and I slide in. She's very tight, but her hole seems to receive me quite nicely and squeeze me, like a virgin.

"Oh, babe! You feel as if Marie hadn't fucked it like a beast!"

Marie laughs and Monica squeals.

"Aah!! You're so deep!!"

We both start moving. Monica hugs Marie tightly and kisses her non-stop. Our bull grabs her firmly by the hips and slam her body down as she powerfully thrusts upward. I hug my girlfriend from behind, fondling her breasts and holding her belly, while pounding her ass as hard as I can.

"I can feel your cock, Marie!" I say, surprised. "It's almost as if we were touching!"

"Yeah! This is so hot!"

"I'm so full of cocks!" Monica moans, she seems to be about to pass out of pure pleasure. "Please! Pump me full of your seed!!"

"Julie, let's cum together!" Marie says, thrusting harder. "I'm getting close!"

"Yes, let's do it!"

We make her scream for a couple more minutes, until we all three start climaxing.

I release my load in her ass, while Marie pumps hers deep inside her pussy. We spend some time pressed together, grinding against her hips, shooting semen inside my girlfriend.

"I feel you... Both... Your seeds... Mmm..." Monica moans.

I pulls out, then Monica stands a little, just to fall next to Marie, tired. She has so much semen leaking from her holes, although the amount flowing out of her pussy is much larger than her ass.

"Good one, gal." Marie slaps my ass and gropes it a little. "Woah, you're so juicy too, Julie. I kinda wanna hit that too."

I shiver a little. She wants to... Fuck me?

"What? Uh... Really?"

"Yeah, if Mon agrees."

"Babe?"

"Mmm... yeah, sweetie... Let her fuck you good..." She moans in her begging tone.

"Alright. I kinda wanted this to happen..." I admit.

"Cool."
