You turned your sister on with a vibrator, but who's gonna fuck her to orgasm?

The deal was a blowjob, but you can fuck your brother too, why not?

Money? I'd rather suck your dick! But know that blackmailing your sister is not good

Bro, stop seducing me with dicks, my boyfriend's calling me

You're fucking jerking me off, bro - just ask for it and fuck me

Sister immediately agreed that her brother's long dick was better than her fingers

You ruined my date, bro! Now where do I get my dick?

Sister was breaking down over a blowjob, but ended up asking for a dick herself

Sis, why bother going to the party when I've already found myself a bitch?

Seduced my brother twice - he both fucked me and writes an essay for me

Asked her brother for money for a rubber dick and he let her suck his

"Sister, when are you going to pay me back?" — "No money, let me suck it!"

"Sister, what do you want for New Year's Eve — fuck or 12 iPhones?"
