The white satin ruffled shirt unbuttoned to his waist and Julia’s image faded into Robin’s image. His cock slowly grew in his pants as he imagined... staring deep into Robin’s eyes. He saw the heat of her lust in them mixed with the look of complete trust in what he was going to do. The ache of not having her in his arms this week slowly faded away as his fingertips lightly grazed her thigh. Robin moved her leg towards his touch. A slight gasp escaped from her lips as Joe’s tips dragged closer to. I spread her ass so as to make her movements easier.She increased her speed and was gripping my body tightly. She was about to cum. I want to time mine too, perfectly. I started to pound her while she jumped on me. We groaned and moaned while the sounds filled the room.We both gripped our asses and cummed at the same time. She held my head and kissed me and fell over me. That’s when the beast woke up in me. I turned her over on the bed. I kissed her boobs over the blouse and ripped it open.I. She told Sis to hold my cock and point it at her pussy.After Mum had said I could put in her pussy, Sis and I had practiced. We had been playing with each other a lot and Sis had used a finger in her pussy. I hadn't put it in Sis, although when she rubbed my cock against her opening she did pull me forward and the head did just go in, just a bit. She told me not to tell Mum yet but she thought my cock would go in all the way just like our fingers in Mum's pussy. We really liked my cock touching. Starting at her toes. I worked it all over her body; breasts, arms, stomach, then her tits, and her thighs. Finally massaging her ass gently letting my fingers graze the sides of her pussy. She was soaked.Now the real worked begins. I started working on her clit softly pinching it between my fingers, flicking it with my tongue until all the blood was making it sick out farther than my dick. I put my face right up to her slit just letting her feel my breath. Every time I would exhale her lips.
