I have been doing my best to fight this temptation but it’s a daily battle. I am attracted to my wife’s younger sister. She is hot and sexy and I have touched her yansh playfully a few times while giving her a back massage. The sharp girl that she is I think she knows. She gives mixed signals but never accepts any direct approaches. Our hugs are unusually longer than normal and on one occasion she felt my hard dick. She just moved in with us and I’m just waiting for the right moment to fuck her.
