Dream on, mister.
Some chicks would do a 3-some with a close girl friend, but a sister?
I wouldn't even mention it to your wife if I were you.
You'll be in the dog house for quite a while.
Just Fuck her sister and get it over with! She doesn't want your ass anyways! You must know if you even do this, there is a dad behind the two sisters! I hope he kicks your ass! You shouldn't even think shit like that, dumb ass!
what a cool fantasy. I'd love to do that with my wife and her sis. I get a little stiffy whenever she's around and flirts with me. I start imagining what she'd look like with her butt in the air and her face buried in my wife's shaved pussy.
well in my case my sister fucked my old man before i even got a chance then when she found out we were together she had a mental break-down and now disowns me and says she was in love woth him first... what a loser...
