Help my girlfriends an oversexed slut!

My Girlfriend and I live far apart. She goes out with her friends to dance clubs when I’m not around. She wears sexy skin tight dresses without a bra. They are low cut and her tits jiggle around and show her nipples. The problem is she dances and flirts with guys and gets hit on a lot. I found out that her friends have a competition going to see who can get the most action and egg her on even though they know she has a boyfriend. A lot of times she says that she is too busy to see me because she already has a date with her other “guy friends” She says she just likes being friendly and having fun. She s it’s flattering that guys think she’s sexy and admits that some want to fuck her, but she doesn’t do it. But she admits it’s fun to flirt a little. I confronted her and d her what she does and she admitted that sometimes she has to “take care of them” to make them stop trying to fuck her. Meaning she jerks them off! Then I asked if thats all and she says sometimes if they want to play with or suck her tits she lets them go ahead and do it because they cum faster and her hands are busy. But if her hands get tired a few times she sucked their cocks instead. and if she’s really tired sometimes she just takes her top off and let’s them fuck her tits instead. But never her pussy.One time when I came over early after she just got home from a date, she had cum all over her tits. She giggled and started smearing it around and licking it. I started getting a boner and she saw it and held her tits out told me how hot it would be if I licked it off her tits, and if I did it Shed let me do her hot friend if I wanted to. So I did. She told me how much she would get off on watching us fuck but that we had to do whatever she wanted. I ended ya doing just about everything to her for like 3 hours. She told me to fuck her friend but not cum in her pussy because she wanted me to take my cock so she could suck it and taste it. So I ended up 69 Ing my gf. She’s a hot girl so I guess I’ll put up with sharing her a little with her “friends”
