f**k him...
stuff ya sister
how big is his dick?
do him
Pack your chit and go home while you still have a sister who calls you sister.
What the hell is chit, and how do you pack it?
You dirty slut, Find your own guy and don't be so shitty to your sister.
Wear some see through nighties with pink lace panties that he can see and see if he gets bigger under those boxers. That will give your answer. If he does then do the same but without panties underneath. Wear more and more revealing clothes until he makes a move and you won't have to.
So, any update?
Walk around in a see through nightie with pink lacy panties. Then leave the panties where he can find them. If they are moved, then take that as a green light to seduce him any way you want.
