I discover my little stepsister taking some pictures in her underwear for her boyfriend and I end up her hard in exchange for keeping the secret.

My stepparents come out and leave me in charge of my little stepsister, I feel very quiet and I go to look for her to find out what she is doing, when I enter her room I discover her taking pictures in her underwear and I ask her that I should fuck her in exchange for not saying anything to my stepparents. She agrees and I give her the best fuck of her life.
