I first realized I had a problem when I was about 13. I needed to masturbate at least one time a day. I spent all my time trying to think of something new to masturbate to. At the time my sister was about 17, and I began to swipe her dirty panties and sniff them while I masturbated.
Most of the time her panties had a nice faint little smell that would turn me on, but on occasion they would be moist and have a stronger smell, this was a huge turnon. On occasion when she would come home late after partying with her friends, she would shower before she went to bed. She would throw her dirty clothes into the laundry shoot before she showered. Her bedroom and the bathroom were on the second floor, and my bedroom was in the basement next to the laundry room. Since I could not go out past 9 at night, I would always be home in my room when she would come home. Once I heard her come into the house, I would turn the volume off on my TV, and listen for her to go upstairs. Once she went upstairs I would go into the laundry room and hope and pray she would take a shower. When her dirty close would come down the shoot, I would feel like I just won a jackpot on a slot machine.
I would grab her fresh panties out of her dirty clothes and take them into my room. I would lie in my bed and put them on my face. I would sniff them and lick them while I masturbated. When they were moist, the smell was such a turnon I would masturbate twice.
After about 3 months of doing this I realized her panties were no longer moist when they came down the shoot. This was very disappointing to me. I figured this was because it was now fall, and the weather was starting to cool off so she didn't get as hot down there. Regardless, I continued to retrieve her fresh panties from the shoot as a stimulus for my ejaculation. Unusually in February, her panties started to come down the shoot moist from time to time. It wasn't hot outside so I couldn't figure out why.
About 2 months later my parents went on vacation and left me and my sister to ourselves. One night when I was supposed to stay over at my friends house but decided not to. I heard my sister and her boyfriend come into the house and go into the family room to watch TV. I decided to go up and spy on them. By the time I got up there my sister had her skirt lifted up with no underwear and she was climbing onto her boyfriends cock. At this point the gears began to turn in my head and I was overcome with shock. Was the moistness in my sisters underwear actually her boyfriends cum. They were broken up during the time that her panties stopped being moist. I went back down to my room and my mind was going crazy. I kept telling myself I wasn't gay, the smell was not his cum.
A couple hours later I heard her boyfriend leaving and she went upstairs. I decided I had to know so I went to the Shoot. After about 5 minutes (it seemed like 1000) her dirty close came down and I grabbed her panties. The panties were moist to the touch and the smell was the same. I threw them back in with the dirty close and went back to my room. I couldn't believe I was getting turned on by a guys cum, I though that was her pussy I was smelling. It took about a month before I could mentally convince myself that it was no big deal and it didn't mean anything. After about another month I managed to convince myself that I wasn't gay if I continued to do it. I still liked girls and was not at all turned on by guys.
The next time her moist panties came down the shoot, I took them into my room to perform the routine, except this time my load was twice as big as the biggest load I had ever shot. I did not know why I was so turned on by the smell, but I wanted her panties more than I ever did before.
It was just a matter of time before I started tasting my own cum.
As an adult this seems like a predictable story, but when you are 13, it is not so obvious. When you spend your years as a youth trying to avoid doing anything that might make you look gay, then you find out that you were getting incredibly turned on by the smell and taste of another guys cum, it takes you some time to find yourself again.
