One of the guys in my Air Force unit took a front motorcycle tire and then placed his erect penis in the center of the tire lifted the tire up and put the head of his penis on a countertop and managed to hold up that entire tire with his hard on!
He had a very hard erection and that would make his shaft go completely vertical along his abdomen and extend just above his belly button almost touching his abdomen, that’s how hard he was when he did this trick. He also was very girthy; and about maybe nine inches? So, a nice cock indeed!
