This event occurred last summer when I worked for an auto-body shop as an errands boy. I was 19 at the time and openly straight. I was bi-curious but had never had any gay experiences, only fantasized.
Every morning myself and an assistant manager would get to the shop early and open up before the technicians arrived. One particular morning the assistant manager were changing in the change room. I unknowingly still had these white cotton panties on that i had ordered online. I had used them the night before to fantasize.
