Fuck her

I second that notion. I say next time she bends over in front of u, without hesitation, whip ur c*ck out, pull her panties to the side and F*ck her hard. Let us know how it goes.

what the hell kind of sister do you have. tht's weird man.

PICS. NOAW.

Tell her to stop or just give her an open hand smack on her face that should do it .

The kind wed all like

Are you from Arkansas? If so, this is perfectly acceptable behavior.

SCREW HER!!

huh... sisters do that if they re smaller than u cause u re like a hero for her. If u try to fuck with him probably she will get angry, embarassed, sad, and will broke any try of friendship relation will u for all ur damn life.
Cmon she's not ur stepsister.

Not tellng you what to do but if I had had a sister I might have fucked her.

That is wrong on so many levels...

skrew her or try and stop her

Euw! what the fuck!!!! its your sister. your sad and can't get a girlfriend!

Tell her to stop behaving this way otherwise you will avoid her. If she continues then stick to your words and distance yourself from her. You don't provide much information about your background. Perhaps you are not related by blood, which would make her attraction more understandable if she is a half sister. I'd establish a boundary and if she crosses it, hold firm.

I think if she crosses the boundaries, he wont have a problem with the "hold firm" part. =]

FU*K HER!!!!!!!

hit that pussy like a caveman!!

O.....she's butter-faced lmao

Do her, then track down and kill stargirl.
