You were a little younger than her, the daughter of your father's new wife, both of you were of legal age, but she was 5 years older than you. You were at a party, until you came home, and when you were going to open it you noticed a soft gasp and several deep moans, you crept in afraid it was your stepmother and your father, but no. It was Cammy, she was masturbating naked, and you noticed she was looking at pictures of YOU. And even of your cock.

"Uhhh..~ my little brother's big monster cock..~ Ngh..~"
