Taboo!! I can't believe it! I was doing my step-Son's laundry and found my panty in his pile of dirty clothes. I thought that was so odd, I picked them up and my panty is drenched in gooey cum. The only person home is my step-Son, I confront him. He admits that he wraps my panty around his cock and jerking off in them because I turn him on so much. I understand that he is at a ripe age, and sometimes mommys can dress sexy and not wear silly things like bras in the house. I had no idea my step-Son would be hard and wrapping my panties around his cock blowing globs of cum in them. Then he tells me how beautiful I am. I am flattered because his own step-Father does not say such things. Seeing now how much cum my step-Son produces has me thinking that he can help with a fertility problem me and his step-Dad are having. I stuff my panties inside me, hoping the left over sperm can enter my body to conceive. My step-Son is getting aroused from watching me. I can't let this go unnoticed. It's best we keep this in the family, my step-Son has a mass production of sperm that can help mommy get pregnant. Please don't tell on me step-Son, please keep mommy's dirty secret. I love you so much..ok? (Cum inside pussy) such a treat for taboo pervs.
