Ok the girl in my picture is my girlfriend, she is amazing beautiful and much much more, but the massive problem is that she has an identical twin who is trying to get with me, i love my girlfriend we've been together 2 years but her sister keeps trying to have her way with me, a week or so ago i was about to have sex with my G/f but then her mum called her and told her to go to the shop, she told me to just wait in the room till she got back. whilst she was gone her sister came in the room and started kissing me and feeling me up, i had no idea it was her sister i thought it was my G/f, and then about 5 minutes later my G/f got back and shouted up the stairs asking if i was still here, that's when i realized who i was kissing, i don't wanna tell me G/f about it because i don't wanna lose her and i don't want her and her sister to break up. what do i do? this isn't the 1st time something like this has happened her sister is always asking me for sex, to go some quiet and more, but i can't a single difference between both of them, it's so annoying. but i have been with her for ages and breaking up with hr isn't an option, she's the only good thing that's ever happened in my life. help
