Baritone

"I used to play this instrument in high school, and I played it naked a few times. I used to play it every day in high school and the bottom of it rested on my crotch, right on my dick. (I dress/dressed to the left.) And every day during band I would get a raging hard-on during band from the vibrating metal on my dick. Imagine. I was a teenager with constant hard-ons." -- Pictures of Naked Men
