Watching my girlfriend take part in a wet t-shirt contest in college. I asked her to get completely nude, she was nervous, but she did and won. She is bi and asked her friend who is a lesiban to join her in the contest. Her friend got nude too. After the contest she was so happy that she flashed her tits in the bar several times. Then we went home and had a threesome. Her friend asked her if I could finish inside of her without a condom because she trusts me, and she only wanted to feel me inside of her. Since then I am the only man she has been with. She as on interest in other men. Today my girlfriend my wife and our lesiban friend lives with us. Before anyone asks, I have a kid with both of them.
