Sex instead of rent? That's a great idea, sister, I agree

Are you a virgin? It's no problem, I'm already naked, bro, fuck me

Holy shit, you came twice! That's what I call missing your sister

Jerking off on my sister, that's not right. You should have fucked her right away

If you show me your tits, you want to suck my dick too, right, sister?

Finally, my brother caught me jerking off - hurry up and fuck me, I don't mind
