At Brad's house

When I was 11, I stayed at a friend Brad’s house. His dad was late 40s but his step mom was early 30s. She was slim with big boobs. Very cute. Hippy type. Brad and I went swimming with her. She wore a string bikini that barely covered her tits. I could see her nips and bush through the thin material when it was wet. When she climbed out, she grabbed a big towel and held it up in front of herself with one hand while she unsnapped the top and slipped off the bottoms with her other hand. She tossed her suit on a chair to dry and wrapped the towel behind herself. She said she would shower and make us lunch, then headed for the house.
