Musty

Today I worked out and then mowed the yard in the afternoon. After mowing I went inside and took off my clothes for a shower. Noticed my ass was very sweaty and my underpants had hree distinct scent zones. Sweat at the waist band, musty at the crotch , and dank and musty in the back. So I fired up XRMXX and jacked off to some of my favorites while sniffing my shorts. Came a geyser!
