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.
Nice pussy, although her breasts are a little saggy and her ass is a little pimply. But I will not pick on her, really very attractive and her lips are working! Except that she wasn't fucked all over and not enough. Judging by her, she wouldn't mind another half an hour on the cock.
Somebody's jerking off to a man's ass.
