I wanted to show my mum whenever I got hard. It was amazing to me that it could grow and stiffen and the feeling was so good when it would throb and h...rden. Mum was apparently relaxed about it, brushing me off and ignoring me, except when it was bath time. If my penis got hard when mum was washing us, I can remember vividly how the atmosphere would change. Mum would wash my brother quickly, lift him out of the bath, dry him and lead him through to the bedroom. As she was leaving the bathroom. Her long tanned legs, slim and athletic body, reminding me of a younger version of her mother.The nightie was a light one suitable for the hot weather we had been having lately with Shoe string straps over her shoulders and a low front showing her budding breasts it was nearly sheer, giving glimpses of her B cup breasts. It was bordered with lace along the bottom edge that came just low enough to nearly hide the white panties she was wearing.We had as a family always been open around the house. He would just say “be careful”. I drove to Peter and Vivian’s house and rang the doorbell. Peter opened the door and I immediately was sorry I had agreed to no intercourse. Vivian met me in the living room and I was sure it was going to be fun. Vivian and I went into the bedroom for a talk. I asked her if it was her idea or Peters. She floored me by saying it was her idea. They had watched porn and the whole idea had got her excited. In preparation she had bought a couple of dildos. One was. I languidly reached for her bra fastener in front and liberated her beautiful breasts. She softly moaned now. I bent to her breasts and slowly licked each nipple in endless circles, while my hands caressed her arms and sides. Too stoned to be afraid she would stop me, I knelt beside her deck chair, and lifted my mother’s little butt up slightly and skinned down her pants and panties as a unit. Here was my mother naked, on a hot sunny day, and I was going to be fucking her in a few minutes.But.
