My step Daughter was 4 when we marrid and had always slept with her Mom so she always ended up in our bed. I worked til 11 at night and when I would come home she would be in our bed. One night I went home andd got in bed naked and put my arm around my wife and there was my step daughter laying face toward my wife. I told my wife this has to stop I am so h**** and whispered Im not weaaring p****** be very still she wont wakee up. I pulled her night gown up and slid in slowly it dawned on me my hand was on my step Daughters a** and my wife diddnt know I got so turned on as I fucked my wife I moveed my fingers so they were touching my step Daughters p**** covered p****. I c** so hard I was afraid I would wake her up. After my wife said why are you so h**** and I said I just needed you. When she slept between us I started waking up with my hard on agains her a** and I would quickly move away and turn over. One Saturday my wife had gotten up early and went shopping with her sister leaving us in bed. I woke up with my hard on prressing against her little b***. I lay there for a few minutes and slid my boxers down and felt her soft skin against my c*** head. I started dripping pre c** and her legs got slick and I couldnt help myself I pumped between her legs but pulled ot quickly and went to the bathroom and jacked off. Now everytime I get the chance which is almost everyday I f*** between her little legs.I would never try to penetrate her and dont take her p****** off as a safety barrier
