It was still so hot inside the house.My sister siting in the chair to the left was still just in her tiny bikini. I began to have thoughts of what lay...beneath her panties. I wondered if she shaved herself or had a little landing strip; I wondered what it would feel like to slide my fingers up and down her little, tight, innocent pussy. As my thoughts wandered in my head I felt myself starting to grow so I quickly grabbed a cushion and layed it on my lap.I think my sister noticed what I had done. I topped up her drink and sat next to her and started to rub my hand on her leg she lent over and kissed me, started to remove each others clothes as I felt her pussy it was soaking wet I gently rubbed her lips as she opened her legs wide enough for me to put my finger on her clit, she moaned and begged to be fucked hard. As i stood up my cock was solid and big her eyes opened wide as she licked her lips.I moved inbetween her legs and slowly entered her she moaned with pleasure as she wrapped. Sexy suit? The one that gets transparent when wet?”Oooh – boy!“Everybody will get a chance, but Mom gets me first,” I said, getting a smarmy smile from Sarah as I saw her lick her lips with her tongue as she said, “Me Next.”She left and went to the room she and Mom were sharing.“Claire and K, could you do a few more things together during the Titanic song? I mean like maybe a deux entrechat or cabriole?”“Listen to him, Kalista—it almost sounds like he knows what he’s talking about,” Claire said. When Chris sat down, she moved closer to him and took his hand. "Chris," she said, "You know what we did yesterday, and the day before, was very dangerous and, in fact, wrong."Chris wanted to cry. "Yes," he whispered. "I'm sorry," he added, still feeling that he had taken advantage of his mother.Allison looked at her son with surprise. "There's nothing to be sorry about. We are both adults... and I do consider you an adult now... and we both should know better."Chris remained silent."If we are.
