As I stood next to the bed, my naked and freshly-fucked sister-in-law Rachel looked up at me. "More sex?" she asked with a hint of concern on her face.
"You don't have to be home till tomorrow morning, and Claire is dead asleep in our bed down the hall. You've clearly needed a good fucking for a long time, and our evening is just getting warmed up."
Rachel's pretty face changed into the bitchy expression I'd dealt with for years. "We both know this wasn't consensual. I've been drinking, and you took advantage of me." Her eyes flashed with anger. "You raped me."
"Oh, Rachel. Rachel, Rachel, Rachel," I said with a measured tone, as I grabbed handcuffs and a gag from the bag at my feet. I quickly grabbed one of her wrists and cuffed it to the metal-frame headboard. In an instant, I was straddling her chest and wrestling her other arm toward the far side of the bed.
"What are you..." she started to say, as I forced a ball gag in her mouth, fastening it behind her head. She was kicking and mumbling loudly. I moved to the foot of the bed and knotted a rope securely to its legs. When she stopped trashing about for a second, I was able to catch an ankle, which I quickly tied down. A few moments later, I had the other one secured as well.
I stepped back to admire my handiwork. In front of me, my slender sister-in-law, with her long, blonde hair splayed sexily around her, was tied spread-eagle and gagged. Her naked body pulled side-to-side in anger, which made her perfect-handful tits bounce. The landing strip she had so kindly shaved pointed at the pussy I had just fucked. My cum was slowly oozing out of Rachel, spilling down her thighs onto the sheet below. Her body glistened with the massage oil I had used on her while feeling almost every inch of her body. And the techno playlist I had chosen actually was excellent in combination with the strobe lights.
I traced my finger up Rachel's body as I walked alongside the bed, making sure to pause to lightly tug on her pussy lips and to slide a finger momentarily inside her. I stroked up her flat stomach and circled around her breasts, giving each nipple a hard pinch.
"You've been such a bitch to me since the moment I met you. And you treat my wife -- your sister -- like trash most of the time too. I know your husband can't be fucking you right if you have so much anger to aim at Claire and me."
Rachel mumbled loudly, showing some of her familiar hatred.
"I really want to take that gag out of your mouth so I can fuck your face. Oh right, Claire told me you hate giving Tim blowjobs even though you were apparently the queen of them in college. I'd like to find out."
Rachel let out a muffled scream into the ball in her mouth, but it was barely audible over the music.
