Open Question: My gf's friend is at it again....can I stay away?

[feedcrawler]

My gf's friend came over this weekend and as we were sitting at the table eating she started to rub me with her feet. She was barefoot and started by just sliding them up and down my shins. When my gf walked away from the table she told me if I say anything to my gf about it she will tell my gf I always hit on her and cause all kinds of trouble for me.When my gf came back to sit down at the table her friend started to rub on my ____ through my pants. I could help but get excited because I have a foot fetish and she knows it, and I also think her feet are very sexy too. I'm torn because I enjoy it but at the same time I hate it because I love my gf. If I tell my gf we are likely to split because her friend will tell her I hit on her all the time. If I don't tell her I am afraid I'll give in to the temptation and possibly will cheat on her if I get the chance to be alone with this girl. Her friend made it known that she would have sex with me if given the chance. What would you do?
