I personally never put on underwear when I am just hanging out at the house. I like to have my dick and balls be able to breathe. As soon as I get home from work I always change and put on sweatpants. Well yesterday my wife had asked me to go out and run errands with. I obliged and went out. We get out of the car and start walking around the store. I noticed people giving me some odd glances, and a few people even glanced up and down my body. I thought it was weird at first and didn’t give it a second thought. Then a woman had stared longer than the rest of people at my pants. I notice only then that I didn’t have underwear on and I was showing through my sweatpants. I wasn’t embarrassed or anything but actually kind of felt a thrill.
