Quite a lot!

The first voice I hear belongs to the gentleman fucking Lacy from behind, "Yeah slut, take it in the ass like the whore you are, fuck yeah," because I am shocked to hear that his cock is actually buried in her ass, but behind his clench-jawed rambling I quickly become aware of my wife's drunken declarations,

"Ooo god you dirty bastard, fuck this married asshole. You fuck me so fucking good. Better than the idiot I'm marrying could ever fuck me."

I have my cock out and am stroking it frantically, almost hypnotized by my slut wife and her mesmerizing lies. And her ass. She has such a glorious ass, that even though she would never let me fuck her there, I feel lucky just to be able to lick her there.

The man fucking her spat her gorgeous tit out of his mouth long enough to tell my wife, "I'm going to cum in both your holes tonight, engaged slut."

"Yes yes yes please." Hannah begs him, "Use me. I love it." She encouraged him further, with many "fuck"s and a long, drawn out, "meeeeeeee!" as he went back to work sucking and gnawing on her nipples.

The man fucking Hannah's beautiful ass neglects her tits once more to let out an animal groan that surely indicates he is spurting his cum deep inside Hannah's tight ass. Hannah squeals incoherently. The man fucking Lacy also proclaims, "Take my cum in your ass whore fuck yes," and the man getting his dick sucked in the car seat rolls his head back and lets out a sound like a creaky door, Lacy's head still moving busily in his lap.

"Now fuck my pussy," I hear Hannah's voice loud and clear, and I cum hard, getting a streak of my jizz on the door I'm peeking through. I manage to suppress a sound from being made when I climaxed, unlike the other four people who had done so in the last five minutes, including my fiance Hannah. She is rolled onto her back with the man's hard cock still buried in her asshole. He slowly slides his glistening shaft from her ass and then slides it slowly into her pussy. This is what I imagine is happening, since I can no longer watch at this moment, overtaken by the shame that tends to follow an orgasm caused by lies, but knowing that the sexual compulsion that governs my life will not be beaten so easily, I keep the door ajar and listen.
