When I was just exiting High School me and my twin weren't the best of friends. At the start of High School we did everything together. But towards the end... we started fading, and in 12th grade we were both fighting over a girl and who got to get her and ultimately at the end of 12th grade he got the girl and I wasn't too happy about that. I had been friends with this girl since 3rd grade, when she first moved to our area, and he hadn't taken a liking to her since that year. Basically, you could say I was friendzoned. Me and my brother looked incredibly alike (We're twins, obviously) and more than once she mistook me for him. They were together that entire summer. It was absolute torture to see my brother and the girl I'd liked since 3rd grade together, kissing, hugging, cuddling. I even heard them having sex once. I'd never been so depressed and jealous in my life. That entire summer was one giant heartbreak. Near the end of the summer, mid August or so, I decided that I'd get back at my brother. I decided that one day when he was out doing something I would dress like him, talk like him, and invite the girl over for a little "fun". She'd never know the difference. The girl wasn't that attractive to be completely honest... but her personality more than made up for it. To be honest, I don't even know why she wanted to be with him, her interests aligned with mine much more than they did with his, but that's aside the point. The day finally came when my brother went to hang out with his friends and I quickly invited the girl over. The phone conversation was easy enough, I convinced her to come over without any problem. I was nervous she'd notice something was off when she got to the front door though. She came over, I tried to act as natural as I could and open the door. She said hello and gave me a kiss. I'd been waiting for that kiss for 9 years now and it made me feel ecstatic. She picked up on my extra happiness I guess and said jokingly, "Wow, why are you in such a good mood today?" I invited her to go up to his room and as planned, we started making out and stripping each other's clothes off. Then she stopped suddenly and said, "You don't kiss like Michael (my brother), It's you Thehealeroftri, isn't it?" I'm a terrible actor, I couldn't act this one off, I tried to let out a laugh and say something like, "Haha, yeah right, it's me!" and try to go back to whatever we were doing. Instead it came out like, "AHAHA, Yeahhhhhhh hahaaaaaaaa." and not nearly as smooth as I had planned. I didn't really know what I said completely because I could feel myself start to shake and sweat. I was expecting her to be disgusted, tell my brother, and then we'd all hate each other for the rest of our lives. Instead she just told me, "I know you've liked me for some time now. I would be with you but I think your brother is more physically attractive than you." Instead of trying to explain how we're twins, I just stuttered a bit and nodded. She continued, "But I won't tell your brother if we get together this once." And with that once sentence all of my fear was gone. I was back in the game with her. We ended up having sex, it wasn't the best, but it felt great. Even more so because I'd wanted to be with her for quite some time now. We layed there for a bit. Eventually I looked up at the clock only to realize 5 hours had passed, my brother would probably be home any second, I jumped out of bed and told her she needed to get going too but instead she layed there and told me to get back in the bed with her. I got back in and tried to explain to her that my brother would be home soon but instead she looked at me and said with a happy face, "I need something from you first..." Confused, I replied, "What do you need?" "I need about tree fiddy." It was around this time I realized that this girl was about 8 stories tall and a crustacean from the paleozoic era. That damned Loch Ness Monster had gotten me again, "Damnit Monstah, I ain't givin' you no tree fiddy!" I yelled as she swam away into the distance. My brother never did figure out what happened to his girlfriend, I never told him about it and he became a bit sad that she stopped seeing him, but hey, that's life. tl;dr: Acted as my twin brother, tried to get with his girlfriend.
