First, your boy that's hitting it now should know she already been through 2 out of the 3 of you before him. Then he's gonna fall in love with a chick, who you say is a slut? Sounds like you were getting feelings, LOL. But seriously, as men we get around, you shouldn't hate cause she is. Ass must be good to pass it around, and if you know he's hitting it and didn't tell your other boy who obviously has feelings for her, what kinds of friends are the three of you?? Just curious.
