By lifting her hips, I knew Sis wanted me to push my cock home. When my cock was fully in we would pause, just feeling the sensations, the pleasure. M..., the warm tight pussy. Sis, the big, hot cock.It had started when Mum had us both in the bath together a long time ago, I can remember she would stand me up and pull back my foreskin and wash me, rinse me and then get Sis to do the same. Mum would wash Sis between her legs, she was different, Sis had to put a foot on the edge of the bath and I. All I had to do was exactly what she said and then I would " get yours". She took me by the hand and pulled me on top of her and kissed me softly but urgently. She removed my shirt and opened up the top of her dress and pulled my chest down against hers tightly. I almost came in my pants! She unfastened my pants and pushed them down and grabbed my cock and began to stroke it - it only took about 4 good strokes and I shot warm cum all over her! She laughed and said not to worry, we can go on. He could feel it inside him. And today, it got the best of him, and he was not ashamed of showing it. So, when he turned around and knew she would see his erection, he became harder, so hard in fact, that he could actually feel the veins popping out as they pumped the blood to keep it up. He could tell when she saw it. He saw how she almost stumbled. Having her see his erection sent even more blood to it and made it throb even more. He wanted to touch it, watch her while he touched it, see how. About a week later we never really talked about it anymore but he was coming over for our routine sleep over , well during a nice game of truth or dare which we always played , I decided too take a dare because game was getting boring , well liam dared me too put on a thong and bra and lipstick and I thought it was a joke but he reached in his bag and pulled out a black and pink thong with matching bra and red lipstick , well I wanted to say no , but seeing the thong and bra curiosity got me.
