Is it normal my girlfriend's sister uses me to practice her lap dance routine?
my girlfriend has a younger sister who wants to be a stripper (dont ask why, i sure didnt) and she needs a man to give a lap dance to as a form of practice. my girlfriend (her older sister) volunteered me for it. i said to my gf "isnt this like me cheating on you" and she insisted that i was being a great helper. i feel bad cuz i get wicked horny from the lil sister's lap dances (i'm not sure why she's practicing, i think she could easily be a stripper, but maybe i dont know what i'm talking about) she also...jerks me off afterward. my gf has no problem with it though. is this sort of thing normal at all?
