I have a pretty good life. I do well in school, I'm fairly popular, almost everyone knows my name (Alex), and I get laid enough to satisfy my sexual desires. My 7.5" cock has pleasured many hot girls, and they've returned the favor to me quite well. I enjoy life very much.
I do worry for my sister, Cynthia. She is a very shy girl. Because of that, she's doesn't have very many friends, which causes her to feel lonely often. I try to help her to meet people, but she never seems to fit in. She's just not outgoing enough. Another problem for her, is that she has trouble in her classes. She tries her best, but she just can't understand the lessons. Our parents often scold her, asking her why she fails. Due to her personality, she never argues much. When our parents yell at her, she usually just runs to her room, locks the door, and cries herself to sleep. I always try to comfort her to the best of my ability. I hug her, and say encouraging things to her.
Although it usually doesn't help much, I can tell she really appreciates it. I am pretty much the only person who truly understands her. We're very close siblings. We both have black hair, brown eyes, etc. Our personalities are one of the only differences between us, aside from gender, etc. We were even born on the same day. I always wonder why she's never had a boyfriend before. I have to admit, even though she's not the most beautiful female I've seen, she is quite attractive. I know it's wrong, but I sometimes think about how my life would be if our relationship was more intimate. Even though I could easily get many girls to fuck me, I often dream of being with my sister. Many times when our mom and dad were out on a date or an errand, I'd even spy on her during one of her many masturbation sessions. The cute little moans she made would turn me on so much that sometimes I would go to my room and play with myself. I normally don't jack off, but watching her was always too much for me.
On our 18th birthday, I got a video camera with a remote control for one of my presents. I'm sure you know how I put it to use. I was able to find a perfect place to hide it in the bathroom. While she took her shower, I used the remote control to tell my camera to start taping. When she finished, I'd turn it off, and prepare for my shower, after which I'd take out the video and watch it in my room when everyone went to sleep. These tapes were better than any porno I'd ever seen.
After a few months, when we had already started college, I decided that if I could seduce Cynthia, then not only would I be the happiest man alive, I could probably improve her self-esteem as well. Both our lives would be improved, mostly hers. We had separate dormitories, but I visited her regularly, since her roommate was usually on a date or dance or whatever. My sister still had her periods of hating herself and crying, so I decided to make my next visit a bit more special for the both of us.
