Last week I had my balls slapped really hard in session.

My Mistress had already spent some time on my balls using a perspex ball-crusher, a seemingly industrial strength vacuum pump, parachute with winch, etc. Then she decided to just use her strength. And she's tall and strong (my ribs are still hurting after a bear-hug and lift 6 days ago!)

She immobilized me on her padded torture bench, ankles and wrists cuffed, thick leather straps across my chest thighs and shins (I think, it was all a bit of an intense blur by then!). Then she started on my cock and balls

Whenever I felt an orgasm growing she slapped me in my already sore balls. It was the most incredible pain. I couldn’t help but try to double up, to turn my body away from her painful slaps. She tightened the restraints on my legs even tighter. Now there was no turning away. More cock-teasing amd vicious slaps. By this time I was actually frightened of the slaps that I knew were coming. They came and I tried to cry to get her to stop. She wanted me to cry. Eventually she relented and gave me an orgasm while crushing my beaten balls
