My step sister feeling trapped takes me for the ride of my life when she wants to give me some nude pictures of her

My stepsis found me naked in bed, groping for clothes while her naked pictures laid spread all over. Afraid of mom who very often beat her, she undertook an exchange – sex in exchange for the non-disclosure of her actions. I saw this and I swallowed the bait hook line and sinker and what followed was a crazy crazy crazy and extremely phwhoosy session.
