All I could do was watch as Marve walked in and had Peggy tied up with her ass in the air, all for the taking. He started to lick her ass and pussy an... I swear I could hear Peggy moaning and screaming through the closed window. Between screams of stop it, there were screams and moans of pleasure. I could also see drips, not sure if she was cuming or if Marve was drooling and using extra saliva. I could now see Marve was getting more excited and he hopped up on the bed, his cock was fully erect.. I don't know how long i was down there but he John pulled me up from his cock that was now glistening with my spit. He turned me around and bent me over the edge of the bed. He leaned into me and I could feel his cock sliding along the crack of my ass as he did. He whispered "I'm going to get you ready to receive my cock". With that he used one of his hands to spread my ass open to expose my waiting sphincter and with the other he squeezed some lube. The cold made me jump but the sensation was. Kristy ran the towel over her face and then lower, drying the rest of her body slowly, as if she enjoyed the feel of the rough terrycloth against her soft skin. Kristy has an amazing body and I couldnt help but blush with admiration taking it in. My sisters movements were languid and drawn out, bending over to dry her legs and feet, she gave me a full view of her round ass, and her thick labia between her thighs. She came toward the closet and I shrank back, holding my breath, but she only hung. I start slow but then I go fast, making her tits bounce a bit. After twenty minutes, milk spurts out of her tits and all over me. I lick it all up."You thirsty?" she smiles.I flip her over and start at her asshole; I dont waste time, I go hard. She screams as if someone stabbed her. I keep going and I notice she's beginning to cry. I go even harder; I dont even give a fuck about my wife or my job anymore. I finally drop her to the floor; she just falls like a rag doll, all weak looking. I start.
