PERSONAL TRAINER HAS TO SERVE FOR THREESOME !!!

My girlfriend was at a job interview at the gym. The boss didn't take her because she was just a shy, grey little mouse? Unfortunately, I have to agree with him. She's really very reserved and doesn't come out of her shell at all... as a test of courage to prove herself, she's supposed to sort out this one guy from the gym for a threesome for us? The only problem is that she also has a boyfriend at home? But she should forget about her bloke now and finally let a good cock do it to her again in a really hot way??
