CFNM may trigger

CFNM is my biggest fetish. It started for me when I was younger. My step sister (since lost contact after my parents divorced) was two years older than me. She caught me naked in the living room as a teen and after that...she made me go naked all the time when we were alone.
At first she threatened me by saying she would tell on me. I have to admit though as time went on, I did it willingly.
I stripped naked in front of her (and later two of her friends) and masturbated while they watched. The biggest thrill for me was when we went to the ranch where my mother kept our horses. One summer we took my sister's friends twice. We went up into the hills, the four of us. My sister made me strip totally naked right outside in front of them and jerk off. It was crazy exciting. I started down my road to CFNM from those years.

The acronym was new to me. [Clothed Female, Naked Male.] But not the fetish itself. I'm glad you've found the forum, Cobi.
