*use of taboo trigger word* Your sister is showering, and you're peeping on her and jerking off. When she catches you, she's super pissed at first, calling you a perv and telling you she's gunna tell all your friends about this. Once she sees how big you are though, she can't help but get curious. She starts teasing you and eventually sucks your cock. She says she wants to fuck, but mom is home and she doesn't want to get caught. She says no condoms cause the risk is better, even though she's not exactly sure if she took her birth control this morning. When you two fuck, you try to be extra quiet, and eventually you fill her pussy up with cum...
