When my step-father was not at home, I watched my pregnant stepmother. I saw how she went to the shower and gently washed her big belly, my stepmother touched her body that my penis became so hard and I could not resist. When my stepmother fell resting, I went into her room and touched her belly, then I took out my hard cock and jerked off. I finished and hot cum covered my stepmother's pregnant belly, I had to run away so she wouldn't notice me.
