Early days eroticism
When I was young I was almost tortured by adolescence. I had a reluctance to masturbate because I felt guilty about it afterwards, but I could not help it at times and was always thinking about it. There was an Asian girl in my class at school that had super soft skin and would wear miniskirts and sit next to me. I would stare at her legs and have an ache in my crotch all day that several times put me close to orgasming in my pants.
I tried to be respectful and know I did not come across as a pervert, but I was always 2-3 tugs from climaxing when I let my thoughts drift too much. The smell of her perfume, her soft skin, and the occasional hug (we were classmates and friends) was too much.
One time in geometry class I was thinking about her and pressing my hardon almost unconsciously against the underneath part of my desk. I did not mean to, but I ended up shooting hot cum into my underwear and pants. I was terrified that someone might have seen and was worried that it would soak through. fortunately, I was able to pull my shirt out and get to a bathroom to clean myself up. Remarkably, I don't think anyone noticed.
As I started dating, if I was turned on, I was always 3-10 jerks away from shooting ropes of cum into my girlfriends hands and all over me and her. There was something so erotic about feeling the heat of my cum between us.
As an adult I sometimes yearn for those days, even though I have control of myself now. I still love the eager tug of a horny woman who loves to make me cum.
