I felt frisky on sunday early morning about 1am. I was watching a film on tv the mrs and step ...... was upstairs asleep. So i looked through some porn on my phone and started pleasuring myself i was solid as a rock with my pants around my ankles enjoying the moment in full stroking mode when the living room door opens and as it opened it was my step ...... who is 20 she was looking straight at me and said sorry as she looked at my cock smirked and shut the door.
I pulled my joggers up and whent in the kitchen said sorry to her and thought you was all asleep! She said dont worry its ok all men do it!. Never been mentioned afain and talks to me like it never happened
