Take a hot guy, Have him wear those underwear for a day, Get his ball smell all over them then jerk off all over them, Nothing is hotter then holding those pair of some anonymous guys hot drawers up to your nose and smell is man sent as you pull your cock. I have taken my husbands underwear with me and pulled them out to smell his scent. Been 15 years and I still do it. When I do the laundry I smell his underwear, Its hot. Makes me horny.
And no, I don't prefer the skidmarks for you fuckers that are going to go there. I paid good $$ for a pair of Calvins that the guy got messy (Cummed on) for me. He taped the whole act and even called out my name as he shot his load. Great touch. I need some underwear now. I'm horny.
I agree Swede, I suck Straightknob too.
