The Bet

I've never been great at winning bets with my sister, she always won. So, I stopped betting with her and that annoyed her as she liked winning the bets. The more I refused to bet with the more annoyed she became. I'm not socially active like she is and so she likes to bet me for money, so she has more to spend. I've always saved my money since I was 7 or 8 and compared to my sister I'm well off. She spent her allowance as soon as she got it, I saved mine. We both still live at home; I'm finished university and got a good career as a result. My sister is younger by 2 years and didn't go to university and works low paid jobs as a result of partying instead of studying. Anyway, she uses to bet me as a way of getting extra cash, I didn't mine losing. But the way she acted after winning got on my nerves, so I stopped betting with her. One big different between us is I don't date or have any social life. I'm not a virgin as I paid a hooker for sex and lose my virginity that way. Of course, my sister was always trying to get to bet her and my refusal, made her wanted to get me to bet even more. She finally came up with a sure way to get me to bet, she offered to let me fuck her and lose my virginity if I won and I give her money if she won. I refused at first and she raised the stakes as it were, 2 fucks. I was tempted and so I agreed, and she made the bet that she could drink more beer than I could. She is smaller than I am, I should win by body mass, but I don't drink that much. But I also knew if I took carbon or charcoal capsules it would increase by alcohol intake slightly and it may be enough to win. Also having a full stomach would also aid my consumption of alcohol a bit as well. Anyway, I accepted her bet and the next weekend our parents were away, we had our beer drinking contest. She got hammered as they say, I wasn't that far behind being hammered also. I was able to video her passed out on the lounge, before throwing up in the toilet. I had won and the next day when we were sober again, I showed her the video to prove I had won. I didn't expect her to honor our bet, but she said I could claim my prize whenever I wanted too. I got an instant hard-on and she saw it and we went to my bed, she let me fuck her and after a rest we fucked again. Since then, no more bets as she just lets me fuck her and I give her money when she wants it and I've gotten her a better job working with me. So, she doesn't need as much money as she uses too. She seems to prefer spending time with me than dating now, as she rules the roost in bed with me and she likes being in charge sexually. Best bet I ever made, I would if needed bet her again.
