My step-son comes home and tells me he saw a man that was not his step-father leaving the house, and knew I was having an affair. He over had overheard me having sex and begging the man to fuck my ass. My step-son threatens to tell his step-father about my exploits. Shocked I beg him not to. He will agree to keep quite on one condition. When he was young he hated oatmeal, but being a good step-mommy I made him eat it always. While he ate it I would read little miss muffet to him. Now his conditions are for me to order a little miss muffet cosplay outfit and allow him to fuck my ass. I had no choice but to agree. He only fucks my mouth and my ass over and over in all kinds of positions making step-mommy cum so hard. Then he gives step-mommy all of his cum.
