Years ago a guy at a ABS would ask for guys to dock in his foreskin. I did after he sucked me bring me to the edge. His hood would reach nearly have way over my &= cock. He'd hold his skin over my dick while I slowly fuck against the head of his cock. Only once did he cum while I was fucking him. I always left his loose skin filled. I saw him used many times. I had him 3 times.
