I was adopted by moms 46 yr old cousin called T when i was 7.Often T would flash her bare bottom from bathroom resulting in me m*********** a lot,went on for years.Visiting her WC one night when i was 17 i heard her moaning.Concerned i walked in to find her lying naked on her duvet f******** herself.She said come on in son, take off your PJs and get on me.Now 55 she still had a full rounded nice figure which made me erect.She said OMG son your really thick as she guided me into her.I reached round and gripped her hips and she showed me how to ride her.As i began f****** her she started to climax several times and then i ejaculated up inside her.This was my first s** ever.T then said thats better than us m*********** isnt it.We rested a little then she began sucking my c*** while i massaged her hips and started f******** her.We enjoyed ourselves for hours and she loved me taking her up the bottom.She yelled as i slipped my c*** between her hips and gripped her hips while she fingered herself.Soon i exploded up her b**,it was fantastic.I learned everything from her absolutely.
