I watched my gorgeous, naked sister-in-law Rachel answer her front door, knowing whoever was on the other side would see her bouncing breasts and long, blonde hair that had been mussed from the intense round of oral sex that her sister - my wife - Claire had just performed on her, after Rachel rode me to a mind-blowing cream pie. I assumed it was Rachel's husband Tim returning from dropping off my friend Zack and Zack's wife Mel, who had both been forced by Rachel to participate in that afternoon's fuck-fest. Claire and Mel, drugged into a sexual frenzy, had been fucked repeatedly in their pussies, asses, and mouths by Tim, Zack, Rick, and me. I knew the aphrodisiacs would still be flowing through Claire's system for a couple more hours and hoped we'd be allowed to leave soon so that I could get another few rounds in with my wife before the inevitable, painful conversation tomorrow.
I guessed that Rachel had restrained me to a chair again, my arms and legs bound tightly, so that Tim wouldn't find out she had let me fuck her again. Tim was still no doubt extremely angry with me for raping his wife a few weeks before, in a perhaps-misguided attempt to screw and then blackmail her into being nicer to Claire and me. Even though Tim had spent the afternoon cumming in my wife, I don't think he would react well to Rachel willingly, much less excitedly, taking my cock into her mouth and pussy.
All of those thoughts quickly disappeared when Rachel led six men I didn't recognize into her living room. She gestured to Claire, naked on a mattress in the middle of the room, playing with herself, her amazing breasts and pink pussy fully on display. "Tada!" Rachel said giddily.
"What the fuck is going on?!" I screamed, looking from the group of men, to Rachel, to Claire, and back.
Rachel sauntered to my chair, knelt between my legs, and stroked my hard dick. "Oh, Jake," she said with a smile. "You didn't think I was just going to get even for what you did to me, did you? I found these lovely gentlemen online to help me really drive home the lesson for you."
I struggled against the ropes but only managed to tire myself further. When I looked up, the six men were undressing. "My Lord," Rachel said, "They have really huge cocks, don't they? Imagine the damage those things will do to your wife!" Panic told hold of my mind, as I watched the men standing in a circle around Claire, stroking their dicks -- all of which were at least nine inches long and as thick as my wrist.
"I noticed something earlier," Rachel whispered to me. "While you hated when Claire was fucked by other guys, what really sent you over the edge was seeing her take a dick while passionately kissing her rapist." She continued to glide her hand up and down my shaft. "That kind of intimacy is only supposed to be for you, right?" Rachel squeezed my cock, intending pain. "Remember when you drugged me and forced me to do that with you?"
Rachel waved happily at the guys and said, "Start with a round of missionary, one at a time, pounding her pussy and making out with her." The men smiled back at us. "Oh," Rachel added, "Make sure to get every last drop of cum deep in her cunt."
For the next twenty minutes, which seemed like an eternity to me, Rachel remained at my side, playing with her clit and giving me a hand job, as the six strangers pulled a train on my wife. Claire came repeatedly, her moans echoing in the room, easily audible over the music from our seats a few feet away. Each time one of them spewed their seed into Claire's pussy, Rachel whispered the new, higher number of guys that had filled my wife that day.
"That's ten men who cream pied Claire today!" Rachel said, after the last of the group came. "She woke up thinking you would always be her one-and-only, but tonight she'll fall asleep knowing she hit double digits!" Rachel reminded me, both of us knowing how much what was happening now would impact my wife forever. My sister-in-law joined the others standing on the mattress around my wife. One of them cupped Rachel's breast, and she batted his hand away. "I made it clear that I'm off-limits when we talked. This party is specifically and exclusively about wrecking my sister while her husband watches." Rachel bent down and rolled Claire to her stomach. Then Rachel gave my wife a hard smack on the ass. "OK, boys," she said, walking back to me with a huge grin, "All her holes are open for business. Don't be gentle, and don't forget that Jake really loves seeing her take more than one of you at a time." The group cheered.
