I want a cock in my ass and pussy!" The guys looked at each other for a second, then the blonde said, "For real? You wanna get double stuffed?" "Fuck yeah I do!" Karen panted.

As I stood there, torn between shock and incredible feelings of lust, I heard Karen say, "Mmmm, yeah, now shove your big dick up my tight little asshole! Yeah, fuck both my holes!"

I wanna get a chance at your sweet ass next time!" "No problem, whenever you want, Gary." Again, her soft chuckle. "Well, we gotta take off, practice this afternoon." "K, see ya later. Call me."
