I can't think right, ever since my dad got in a car crash and is suffering from a coma I just have been fucked up. I'm 17 and my sister is also 17, were twins and have the same birthday, but when I turned 15 I realized what a hottie she is. . . my dad hadn't gotten in a car crash back then, and I hadn't felt too strange for my sis, but I still thought she was hot. By the time I was 16 I had fallen head over heals for her, helping her carry her books, giving her a hug before we separated to go to lunch or classes, and fighting with her boyfriends. . . I've always regretting chasing them off since she was always so pissed when it happened, but some part of me felt good to know shes somewhat single again. Then one day after school we were sitting on the living room carpet playing Scrabble (Shes a fucking genius at that game) I had spelled the word "love" she didn't think anything of it, until I found a way to spell "you" she looked at me like I had ten heads, then I leaned in and kissed her, I knew it was very, very wrong, but I just had to do it. Her eyes flew open and she started to pull back, but I held her by the side of her head so she couldn't when she stopped rejecting me I slipped her the tongue, then she flew back, wiped her mouth and said "What the hell is wrong with you?!" my heart sank when she said that, but I stood and she went into her room and locked the door. I banged on it till she opened, and she was standing there will the most mad face I've ever seen, I asked her what was so wrong with kissing me and that I wasnt planning on getting her pregnant. We had a VERY long talk after that and I kissed her once more in the middle of that conversation, she didnt reject that time and it lasted so long, I had to admit I had a boner, but I didnt plan on having sex with her. . . so we slipped eachother the tongue and had as much fun making out for about five minutes until she pulled away, turned her head, and whispered one word "leave" I keep trying to kiss her each few months, and it lasts for about five minutes each time, but she is always the person to back away, the night we first kissed I went to her door after supper and I heard her crying, I wanted to come into her room, but I knew it would only make things worse, so I left. Every time I kiss her we always seem to get closer and closer to having sex, even though It bothers me deeply to know I wanna fuck my sis, I always end up doing it anyways. . . I'll put up another post when she allows me to strip her down to nothing instead of a bra and panties.
