I was trying hard not to think about the way her shoulders curved down across her collarbones and across the top of her breasts. Those beautiful perky...B-cup tits that I imagined were topped with the most luscious cherry nipples. ‘James,’ she called from the bathroom door which she’d cracked open enough to hold out her wet wardrobe, ‘here’s my stuff. You hang those up, I’ll get in the shower and then I want you to come talk to me, okay?’ ‘Sure.’ I went over to the door and collected her wet. I was really embarrassed, and tried to hind what i had been doing. She knew exactly and started teasing me, she started asking me if I had a girlfriend or ever seen a girl naked or kissed one .... I hadn't. My sister was a slim, fit 19 year old into sports and had an athletic body. I often used to get aroused and horny when seeing her walk from the bathroom back to her room naked or with just a towel around her. I had jerked off with her image in my mind loads of times. She asked me if I. Mandy was looking serious then a light seemed to beam on as her face brightened. She dipped her head. Coyly looking back up at him almost through her eyebrows she asked, "Do you think we can do it again?" What?" You know, SEX!"When Bob just smiled at her she was very confused."I know it hurt when we started before but then, inside, that great feeling spread over the entire inside of my belly."Can we do it again. Please?"Bob, grinned and then laughed a little.A big question mark showed up on her. My cock was as hard as iron and I was groping two tits on two different girls at the same time. It wasn't long before all three of us were stark naked and I was kissing one while fingering the other. I don't know which one I fucked first and we did all sorts of combinations. I remember at one particular time that I was kneeling on the floor licking one of them when I looked up and saw them French kissing. It was an incredible turn on.Anyway, we continued non stop sex for a few hours and I.
