One night while my wife and step daughter were in bed i started to watch a porn movie.as a girl was giving a guy a sweet bj i took down my pants and took out my cock rubbing it nice and easy enjoying the scene. Well i noticed movement in the tv screen i turned around to see my step daughter sitting there robe open rubbing her pussy though her panties. I said did you like what was on tv she said yes and also my show.so now on occasion we get together and watch porn and masterbate nude in front of each other.no touching maybe wife would join in.
