I read another story months earlier about jock straps and wanted to share mine. When I was entering puberty my dad was heavy into jogging. He wasn't extremely modest and would strip out of his sweaty jogging shorts walking to the bathroom in his jock strap to take a shower after his run.
For what ever reason, I found my dad's sweaty jock strap strangely erotic and would become amazingly hard. One day, after he finished his shower I entered the bathroom and found his jock strap in the hamper. I immediately grabbed it and went to my bedroom. I was so excited and so hard. I jacked off with the damp jock strap in my hand, smelling it, tasting it and rubbing it around my face and chest. It was like an aphrodisiac to my adolescent mind. It seemed so male and had my dad's sweat and scent, which made me blast my cum faster than I would have liked. I used to imagine what the jock held inside and that image drove me wild. From that day on, I was constantly looking for dad's jock in the family clothes hamper. I don't think my dad had any idea that his sweaty jock strap was giving me so much erotic pleasure.
