When I was a teenager I used to baby sit for my parents friends. A younger couple than them. The guy was a cadillac salesman, and fucking hot. Gold chains and all! After the baby went to sleep, I'd go into the their laundry bin. I'd find his dirty underwear that he had worn that day at work. I'd get undressed and take turns wearing them next to my own large hard teenage penis, watching tv etc, and putting them on my head so I could smell is cock and ass. I'd eventually stroke and I'd shoot some of the hottest loads ever!
Still love guys dirty underwear to this day.
