Stand up, both of you, I said quietly, as the two obeyed. I took a moment to compare the two beauties in front of me. My wife of sixteen years was a g...ood foot taller, had paler skin, and had larger tits, a good cup size larger. She kept her own mound shaved clean, and I could see the cleft between her legs glistening slightly in the dim light. I realized that tonight, shes had to listen to every dirty thing Marci and I talked about, and heard me cum in her mouth, then retell her own first. My other hand touching your bikini covered breasts, finding its way inside the fabric, connecting with the warm sensation of your skin, gently pinching your already hard stiff nipples. You'd grab backwards, releasing my almost hard dick from the confinement of my shorts, stroking it back and forth, feeling it harden in your hand, as if you were moulding it with your lust.I'll start to kiss you more intense and bite you gently on the side of your neck, kissing your ear as my hand ventures from. With no effort I enter her cunt hard. I am pulling her hair and fucking the shit out of her. She is coming hard. I pull out and throw her on the bed and climb up and begin to fuck her 36D tits. Within a few minutes I unload on her face! Tracy just smiles and says it is time to sleep. She is out in minutes wearing my load. What a slut!Saturday we wake up. I decide I want to eat her cunt for breakfast. So I proceed to get in between her legs and begin to feast on her cunt. She is getting close to. Then I heard Bob?s car pulling out of the driveway. Bob had not said one word to me the whole time. I had not said a word to him. Eventually, I got up and dove in the pool. I picked up the bikini bra and the remains of the bikini bottom and went back into the house. Dinner that night was again completely normal and uneventful. After dinner I went back to my room. I was trying to think about everything that was happening. I was sleeping with my sister?s husband. How long could I keep this up.
