I don't know what to do. I am completely turned on by my gf's sister. Whenever we hang by the pool and she is in her bikini I get hard instanty. Everytime she has a skimpy outfit on I can't help but to think about fucking her. I don't kno what to do

how old is she?

She is only a year younger then me and my gf.

Ummmm you gotta problem like she turns you on more than the g/f?

I felt the smae way about my mother in-law

My wife's sister is a lesbian and I often think of her and her GF going at it when I see them together.

i get the same everytime i c my 2 sis in laws i get instant hardon and imagine wild fantasies with both of them together mmmmm

I think that happens alot it's just a what you can't have you want sorta thing. It would be better to deffinitly have a GF than potentially not have any

sneek os a picture of her, and gf, we will enjoy both

I had a strange attraction to my wife's sister. It wasnt helped any by the fact she lived with us for a couple months 3 different summers.

Do nothing, except masturbate. If you tried anything and your gf's sister objected, you'd be in deep doo.

I used to be in the same situation,my philosophy was there are plenty of fish in the sea so i went for it, gf got rid of me as soon as she heard about it and i didnt get layed by the sister. If you do try make sure both chicks are drunk as shit first. Either way its over with the gf though.

Yeah my wife has a 19yo sis i fantaisze about all the time.. and fantasize about a 3some with both. She's my favorite fantasy.

My girlfriend has a younger sister. What's not to fantasize about. It's pretty much what my girlfriend looked like 5 years ago.

I get the same feelings when I'm around my sisters husband. I get moist and later fantasize about fucking him, or having a 3some with my sister and him.

She tells me he's very well hung, which drives me even crazier to see it and masturbate, fuck and suck him off. What's a girl to do?!! It'll never happen.
