I would go into her bedroom at night wearing my pyjamas and sit on her bed talking to her. I would purposely ensure that my pyjama trouser opening was...indeed open and that my cock could be seen, she could not fail to see it through the opening of my pyjama trousers. That would be the extent of my sexual activities with my sister, I found these events immensely erotic and I would masterbate fantasising about them later. What she thought about my displays I don’t know but she never complained or. Four years past my fortieth birthday I had more or less stopped feeling these sorts of feelings. Shit, Asa and I hadn't been intimate in weeks and although that sounds depressing I had gotten used to it. It was like when my eyes started to go and had to get glasses. There was an adjustment period but I was used to them now. I was used to jacking off a couple times a week when it was quiet and I found myself alone at the house. I left #1000 on the table. I think my beer had been #600 on happy. Grace collapsed on top of me when she'd finally cleaned the sperm off ofmy face. We snuggled closely, her boobs pressed firmly against my back,the cock she'd fucked me with lying between my thighs, squeezed againstmy now soft penis, one hand holding me tightly to her by squeezing my ownhuge knocker.We lay there silently for a while. I didn't know what to say about whathad just happened. Before long, I recognized the sound of Grace's evenbreathing that let me know she'd fallen asleep. But I. She had done this with other women; wives of other couples with whom they had swapped partners, but going down on a girl young enough to be her daughter was something she never expected to be able to experience.The teenager was responding to her practiced tongue with unabashed pleasure, wiggling and pushing her pussy up into the older woman's mouth without a bit of shyness. Melanie suddenly saw movement in the glare of the spotlights, and looked up to see Chad watching them from only an arm’s.
