In my sophomore year in college, a classmate of mine did this a couple of times, which i guess started my interest in seeing people in public in clothing that is not normally worn in public. It was a warm spring Saturday, right before the start of mid terms, I was in the library, sitting at table studying, when another guy from the same class, Ian, sat down across from me. I was so engrossed in the chapter I was reviewing, that I did not even notice him sit down. After gaining my attention, we spent the next couple of hours reviewing and studying together until we got hungry.
We decided to walk to the student center to get some food. As we were leaving the library, i noticed he was wearing a t-shirt that was was long enough to reach his knees. I didn't think much of it, since the sleeves were kind of big too, so I just figured, he had a shirt that was way to big, for him. After eating, we saw that one of the study rooms in the student center was open, so instead of going back to the library, we grabbed that room, along with another guy from our class whom we encountered while eating. After getting set up in the room, i headed to the restroom to pee. Ian went as well. since it was a smaller room, with only two urinals (this is before dividers existed), Ian walked up to the urinal next to me. Out of the corner of my eye, I saw him lift his shirt, and start to pee, while it didn't quite register at the time, it didn't seem like he unzipped anything, or lower a waistband. I just finished up, washed my hands and went back to our study room. Ian came back and sat down on small couch, while i was at a table facing him, while our other classmate, Gene, sat at the end of table to my left.
It wasn't until about about 30 or 40 minutes later, while we were discussing, an issue, when Ian, lifted his right leg, and rested his right foot on his left knee. This effectively gave me a view right up his shirt, where we could plainly see his cock, resting lazily on his loose ball sack, nestled into his light brown pubes. Gene asked, about his lack of pants, Ian shrugged, explained he hadn't done laundry and was out of clothes and borrowed his roommate's t-shirt (apparently, his roommate was a football player and was three times the size of Ian). We laughed it off and continued studying, and laughed off the other guest appearances, Ian made that afternoon.
I am guessing Ian was really lazy with laundry, because I saw him a few other Saturdays around campus that spring just wearing the same shirt. I always would ask, having laundry trouble, and he always said yes.
