I stood at the foot of the bed, naked and glistening with sweat, having just shared my sister-in-law Rachel's pussy with my friend Zack. Double vaginal was a long-held sexual fantasy I'd finally experienced. But in my post-orgasmic haze, with Rachel and Zack on the bed, equally satiated and foggy, I was watching Rick strip off his clothes and start to stroke his cock.
"What the hell is going on here?" Rick asked me. "That's your wife's sister, right? My boss Tim's wife? Man is she a hot piece of ass! Look at those tits!" He had jumped on the bed and was squeezing one of Rachel's breasts while running a hand down to her pussy and jamming a finger inside her. "And shit she's wet!"
I snapped back to reality and pulled Rick's hands away from Rachel. "Stop that, asshole," I said, and Rachel looked relieved.
"What, man? I want a turn!" he said, as if he didn't understand why that wasn't exactly what should happen now. "You guys are married to your pretty wives. She's married. You were all fucking. Damn she was talking dirty. I just want to get some too."
Zack scooted out from under Rachel and stood up next to me. Rick was lying next to Rachel. The music pumped, and the strobe lights swirled around us.
Rachel looked at Rick. She had an obvious distaste for him and had known him for years as her husband's pudgy, mediocre underling. I'm sure she had been as much of a bitch to him as she had been to me. She liked knowing men found her attractive, smugly thinking that made her better than them. Her cruelty was a practiced art, and my plan for this entire evening had been about getting revenge on her by fucking the bitchiness out of her. My goal had been to make her my slut and lord that power over her afterward to cower her into kindness toward my wife Claire and me in the future. Getting to tag-team Rachel with Zack had been an unexpected, fun bonus but having Rick involved was definitely not any part of the plan.
I could see Rachel looking at Rick's belly with disgust, and it was the exact expression I hated. God, she could be such a bitch.
"OK," I said with a nod. "You can fuck her."
"What?!" Rachel said, looking at me. Rick moved with surprising quickness and was between her wide-spread legs and forcing his cock into her pussy before she could even turn to look at him.
