A week ago a guy was playing with my nipples, pinching them really hard, he had a lot of precum and used it to pinch my nipples.
Two days later i realize there was small scabs around my nipples. I am sure that he cut
my nipple while he was pinching them. I'm not sure if it bled or not (i didn't notice any blood anyway) but it must off tore of abit if there was a scab.
