I had a model recently who had 7 inch trails of pre cum dripping and drooling for three hours from the moment he dropped his pants, (in the hallway on arriving.)
Just wish I'd got some shots of it, but he kept wiping it away with a tissue (there were a soggy pile when he left!) It was reall-l-l-y wild, hard to draw though he would not stay still, fondling, jerking and moving around the room.
Quite the exhibitionist, wicked body and wild cock.
Wish I'd had a chance to "capture" him under more controlled conditions.
The drawings I did do didn't do it justice.
Any way, about pre cum I've never seen so much and so active.
