I was in a bad situation, but it was of my own making. My plan to get revenge on my bitchy sister-in-law Rachel had led my wife Claire, my friends Zack and his wife Mel, and me directly here. Zack and I were tied to chairs, staring at our bikini-clad wives, mere feet away on a mattress on Rachel's living room floor, in the throes of ecstasy and overwhelming horniness. Rachel had spiked their drinks with the same aphrodisiac I had used on her and was planning to force Claire and Mel to experience every sex act Zack and I had done to Rachel.
My sexy, blonde sister-in-law, wearing the same red bikini she had on the night we assaulted her, stood next to her naked husband Tim, between us and our wives.
"What did you start with first, Jake?" Rachel asked, smiling down at me. "Oh, right, you can't talk with that gag in your mouth, but I remember it was a massage." Tim handed her a bottle of massage oil, and she squirted some on my crotch. She slowly stroked my dick, while Tim looked at me with a scowl. My cock was soon rock hard, and Rachel switched to Zack's dick, while continuing talking to us. "Of course I told Tim exactly what you did to me when I got home. He wanted to kill you, but I convinced him to think with his smaller head."
Tim shot her a sharp look. While on the drugs, Rachel had confided that my cock -- which was about the same size as Zack's, both a bit over average length and thickness -- was notably bigger than her husband's, which I could now see was true.
"Don't pretend to be upset, Tim," Rachel purred. "You know it gets the job done, and these two will see that soon." Zack was now fully-erect as well. "Jake, you may notice throughout all of this that Tim added some pills to your drinks to make sure you and Zack stay hard the entire time. That's going to come in handy later," she added with a bitchy laugh.
Rachel and Tim joined Claire and Mel on the mattress, covering their legs and stomachs with massage oil, before turning them onto their stomachs and lathering their backs with more oil.
Claire picked her head up, looking back at Tim who was focused on her while Rachel handled Mel. Claire slurred, "What are you doing? Wait, are you naked?"
"It's ok, sis," Rachel said, patting her on the head. "Jake is right here too. Tim and I are just giving massages to return the favor."
"Oh, ok," Claire said, returning her head to the mattress with a smile, as Tim began stroking her body. Rachel was doing the same to Mel. Soon, Claire and Mel were both moaning. Minutes later, their bikinis had been removed, and Rachel and Tim were kneading the ladies' asses. Tim looked back at me with a smile as he spread Claire's legs and slid his hand down to play with her pussy lips, which elicited a loader groan.
"Tim can't wait to fuck her ass," Rachel needled me, "but that won't be till later."
Rachel and Tim then flipped their respective victims onto their backs, legs spread wide. I was staring directly at my wife's wet pussy, only feet in front of me. She was clean shaven, as usual, with her large clit and puffy, pink pussy lips on full display. I glanced over at Mel. Her pubic hair was trimmed short, the black standing out in contrast to her pale skin. I couldn't see any lips poking out, and her hole looked small and very tight. Her breasts were small, but her nipples poked out at least half an inch. Rachel was now gliding her hands over Mel's tits, stopping to run circles around her nipples and occasionally give them a light tweak.
Claire's moans brought my attention back to her. Tim was playing with her large, but still perky, breasts. He held them in his hands, batted them back and forth, and then sucked on one of her nipples, as his hand trailed down her body to play with her clit.
"Fuuuuuucccccckkk," Claire gasped, as Tim slipped a finger inside her pussy. He quickly positioned himself between her legs and was soon pounding her hard with his stiff cock. Claire's eyes shot open, realizing what was happening. She weakly pushed at his shoulders. "Only Jake can do that," she said sternly. "I only want his diiiiiic..." Claire trailed off, as her body started shaking with an orgasm.
Rachel was kneeling at my side, again slowly stroking my cock while I watched Tim fuck my wife, and whispered in my ear, "I know how much it killed you when Rick fucked Claire, while she was asleep from the pills you slipped her. You really hated that he came in her, so you made me lick every drop from my sister's pussy." Rachel moved her hand faster on my shaft, causing me to moan into the gag. "How many times have you jacked off thinking about that? Or spit-roasting me with Zack? You're going to see that happen to Claire soon, but first we need to fill her up with cum so she'll always know her little pussy isn't just for you."
As if on cue, Tim grunted loudly and stopped moving between Claire's legs. He pulled out of her, smiling broadly. "That's a week's worth of cum I'd been saving up to spray in your wife," he shot at me, his erection bouncing slightly up and down. "I took some pills to keep this thing going, so there's plenty more where that came from," Tim added, staring at Mel.
Rachel turned her attention to Zack, grabbing his dick while still stroking mine. Tim had helped Mel to her knees and was guiding her into doggy position, with her head between my legs. "What's happening?" Mel asked, as if from a long distance away.
"Zack's right here, Mel," Rachel said gently to her. "Remember that you two wanted to try something new?" Mel looked at her blankly, but her expression turned to pleasure as Tim started rubbing her clit from behind. Rachel had placed Claire next to Mel, also on her hands and knees, their hips touching, and Claire's mouth just inches from Zack's cock. Claire looked up at me, confused, then moaned as Tim began playing with her clit as well.
