Ok this is a really wild story.
I believe I was 16, and I was hanging out with a friend at his house. It was the weekend, and we were just kinda lounging around and relaxing. I tended to hang out with him for the entire day around that time, because neither of us had anything better to do those days. On that particular day, we had just watched a bunch of episodes of Futurama and had eaten a bunch of junk food from Wawa. Halfway through another episode, he closed his laptop screen and said that he was going to take a nap. This wasn't very strange to me, as we'd had sleepovers before. What was different this time was the we were the only two people in his house. His parents had taken his twin sister to go shopping or something. Suddenly, I felt a lump in my pants. "Oh man,", I thought, "this is not a good time for an erection...". I immediately hurried out of his room to avoid an awkward encounter, and also to figure out what to do with my random boner. As I walked out of his room, I saw this his sister's room's door was open. I then had a marvelous idea. I first returned to my friends room to see if he could be awoken easily: nope! He was sound asleep. A tornado could've probably hit his house and he still wouldn't have woken up! Excited, I ran back to his sister's room. I immediately saw my goal: her dirty laundry basket. Now since we all have foot fetishes here, I'm sure you guys can guess what happened after this. I was a horny teenager who had a huge crush on my friend's twin sister, and tons of her dirty socks were right in front of me. I took out a pink pair and smelled them. They smelled heavenly. The perfect mix of a small amount of sweat and her personal odor. I inhaled every bit of the smell and could feel my penis growing even more in my pants. I remembered that his sister also did lacrosse, so I looked further in her laundry bin and found the white and maroon socks I knew she played lacrosse in (they were our school colors, and students were required to wear them for school sports games). I barely reached my body halfway in the laundry basket before I could smell an even more overpowering scent of the combined odors of all her other socks. I grabbed the pair of her lacrosse socks and took a long whiff of them too. That was probably the best smelling thing I'd ever experienced. Her lacrosse games always lasted for a few hours, and she always left her socks on around home too, so these things had ample time to soak up all of her sweet smells. I smelled long and hard again, and then had another amazing idea. I took a pink sock from earlier and whipped out my dick. I but my raging boner inside of that sock. I don't know why, but the fact that my penis was touching her sock was just so hot to me, and I immediately started jerking myself off into her sock. I kept smelling the lacrosse socks while masturbating and let me tell you, this was the best jerk off I'd ever had. I didn't want it to end. I almost didn't even want to cum, because it meant that I would stop smelling her amazing socks. I kept smelling and jerking for what felt like an hour, completely forgetting that my friend was asleep in the next room. When I finally came, it was the biggest orgasm I'd ever had. I hadn't masturbated for a few days before that day, because I was just busy with schoolwork and stuff. This hot load of cum filled up her sock as I caught one last satisfying whiff of her foot aroma. Stunned after cumming, I kind of just stood there in place, marveling at what I had just done. I immediately wiped the rest of my cum off my penis with the other socks I was smelling, and quickly hid them back in the laundry basket. In a fit of euphoria, I stumbled out of her room into the bathroom, to wash my hands. After this, I returned to wake my friend up, and we continued to hang out until I left before dinner to go back home. And that was probably the hottest foot fetish experience I've ever had. My friend's sister never found out, as no one digs in their dirty laundry basket normally, and I saw her wearing the same pink socks I'd cum in next week at school. Sadly, I never had another chance to smell her dirty socks again, as my friend revealed the bad news that his dad had received a much better job offer in another state. They moved shortly after the school year ended.
Hopefully I can win this contest lol. Regardless though, it was fun to recount this memory and write about it. Thanks for doing these types of competitions D4.
