This story is 100% true. I'm a 24yr old male with a high sex drive. My girlfriend of 3 and a half years is 25, extremely good figure, very sexy. She has always been totally committed and loyal to me. However I've always known that deep down she's sex crazy and is naturally attracted to other blokes. I began to get sexy thoughts about her being fucked by someone else etc when I became curious of the swinging / cuckold world. Whenever I hinted this to her she told me to stop being stupid and that she could not understand why I wanted this. I've gone from dripping minor hints to outright telling her that I'd love to hear about her going out getting fucked by a stranger. She said it would never happen. We have since sat down and I explained that I love her just as much but accept sex is sex and IF she ever did fancy someone she could have sex as long as she told me and as long as there's no feelings involved. Anyway, nothing more was said on the subject until Sunday when she was going on her girls holiday for a week (she's still there now). We had a conversation About her friend who is always having one night stands and guaranteed to be doing the same this holiday. I explained that id love it so much if she called me up one night telling me she's been fucked! She said she would let me know if she had but I knew she was just saying this to shut me up. Anyway, about one hour ago at 0530am I was woken up by my girlfriend. She was very very drunk. She said she's just got In and been a naughty girl. "You know you said you wanted me to get fucked? Baby don't be angry but I have fucked someone tonight" Wow. I was in total shock. My cock was as hard as a rock! I asked her to tell me the details. She said she was in a bar with her mates when she noticed a group of young blokes quite muscly but not too much (like me. She doesn't like too much). Her friend began to talk to one and her other friend by this time had gone home. So she had no choice but to join in with conversation when the bloke who was eyeing her up all night spoke to her. Although she thought he was fit, she didn't think anything more than that. As the night went on he was turning out to be a really nice bloke. Making her laugh and buying her drinks. They began to dance and she suddenly got that tingly feeling In her pussy she always tells me about when she's horny. She was thinking about me and the fact she was taken. But she then remembered everything I've ever said to her. She told me that she began to kiss him. One thing led to another and they were quickly back in his room!! They fucked for about an hour, then she left and walked back to her hotel. She said she felt really dirty and hoped I wasn't angry. She told me her black thong is soaked with her pussy juice. I've told her to keep her thong from tonight safe for me so I can fall in love with the dried white pussy juice stains and tell how horny she was! She said she's going to bed now and will tell me more when she wakes up. I'm so horny I can't stop thinking about her getting fucked! Hopefully she will do this again tonight!
