Robin jumped to take Paula's place. She spread her pretty pussy open for me as I dove in. Oh, this was wonderful, I thought, and there are three more....Hmm, well, I don't know. One of the remaining girls was my sister, Tina. She's still got her pajamas on, she's the only one with any clothes on at all. Well, maybe I don't blame her.Without waiting on her to do it, I reached up and spread her lips apart and began running my tongue around and around the opening which immediately got her trembling. She spread her legs apart as I moved in to rub my hardon against her pussy. I felt her sweet tits as he rubbed her hand over my semi-hardon. This was the hottest one yet. I put my hand down the back of her little shorts and felt that smooth ass of hers. She put her hand down the top of my shorts and started feeling my bare hardon. We both trembled a little as it was a real turn on for both of us. We heard mom and broke it off quickly. I had a big shirt on and the shirt tail hid my hardon. Mom. "Wait a minute. Please, I really wanted to talk to you. Can we step outside for a minute?" His face looked sweet and sincere. I looked around for Kelly, who was busy flirting with a guy and I felt selfish pulling her away. "Oh... alright." Brad took my hand and lead me to the back of the house through the kitchen and out the back door. Christina's backyard was large and lead to a section of trees. Passing some drunk smokers on her deck, we descended the stairs to the grass and walked out of the. This was starting to get out of control. Her bra was unclipped and fell to the ground. Annie blocked all this out; she just wanted Pete to come so she could get this over with. Grabbing the shaft of his dick in one hand she sucked as hard as she could. Bill’s hands were all over her; squeezing her breasts, sliding up her skirt and between her thighs. With Pete’s dick in her mouth and Bill fingering her pussy, she glanced at her husband. He hadn’t moved but was staring intently. When Pete did.
