Fit M43 here. My gym has individual shower stalls with curtains. I was in the last shower stall and left the curtain open just a couple inches. Easier access to my towel and to deter someone from taking my stuff.

To my surprise, I noticed someone got in the shower stall immediately opposite mine and also left his shower curtain open a few inches. He was watching me. Younger guy…late 20s or 30s.

This quickly got me hard, which he noticed. He started stroking. So did I. Watching one another. So much contact. I quickly came…then he did too. Was so hot!

No physical contact.

Never thought I could have that effect on someone…especially younger than me. Low risk, great experience!
