My stepsister had taken me to this stupid holiday party and it was a complete bust. I was so fucking horny and those stupid dating apps were worthless. Sometimes a woman had these urges and needs. I saw the way my step-sister's step-son looked at me and undressed me with his eyes. I was feeling festive and wanted to show my little stepnephew aunty's new boobs. They felt so real when he squeezed them. I was going to teach my stepnephew how to cum for his aunty. My stepnephew's big cock was my best Christmas present.
