That's the kind of slutty sister every brother would let work his testicles. And this one probably accustomed her to these pranks a long time ago. At least that's what I would have done. She'd have to suck and spread her legs anyway, so why not with her own man? It's about time she got her ass printed, too, so she can date like a grown-up bitch. Or maybe she's still trying to keep her anal virginity for her husband.
You can't trust blondes. She's willing to give her brother a new haircut between her legs just to be appreciated. I understand him - it is impossible to break away from such a body, even by force of will. And then we wonder why some chicks don't give it up on the first date. It's because they have brothers who string them up before they do!
