Where is the weirdest place you have masturbated?

[Everhard]

In the boy's bathroom in middle school.
In my grandmother's bathroom. (I was 13 and perpetually hard ._.)
In the back of my history class in 8th grade. (Through my shorts.)
In my family's pool.
In the bathroom stall at several public pools.
In a public pool shower. (Meant to be for showering the chlorine out of your hair after you swim.)
In a park bathroom.
In a friend's livingroom while he and another guy watched.
In my sister's livingroom while she was in the shower. (She had free adult PPV because she stole satellite service.)
In my mom's bf's bedroom. (looking at porn on his computer.)
On a bed I shared with my older brother.
Under the bleachers (seats for watching people on a sports field) at a park. Though I didn't cum that time.
In bed with my brother watching me.

I'm fairly certain there are others but I can't remember them all right now...
