28. She starts cheese-grating my dick but at the same time punching my balls at every stroke.
“My ex-girlfriend was never very good at giving handjobs and I realized the first time she gave me one.
So she unzips my jeans and pulls my dick out then gently caresses it. After a little while she starts cheese-grating my dick but at the same time punching my balls at every stroke. I’m squirming in pain trying to roll into the ole classic fetal position but she thinks I’m nearing climax and grates harder.
Get out of there, assess the damage. Had 3 big cuts on my junk that put me out of action for a week. Turns out doing anything with a cut penis is horrendous.”
