DON'T TELL MUMMY! STEPBRO CAN ONLY DO ANAL?!

This wanker, I catch my stepbrother jerking off to my pictures. He can't be serious, I'm his big stepsister! But fuck, now he's got something on me and threatens to tell my mum. And I'd rather my mum never found out, she's such a strict Catholic. To keep his mouth shut, he offered me a deal and wants to fuck me. But only in my tight little arse. I hope he doesn't tell Mammy...
