For a certain fee now any stranger is ready to take off her clothes, spread her legs and suck the first man she meets. Every cute girl is weak in the face when she sees bucks in front of her. I wouldn't want to be a pickup artist because it's a risky business to fuck unknown holes. Sure you can use a condom, but rubber doesn't always save the day.
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.
The kid's cute.
