OK I have a Mistress that enjoys kicking, kneeing, and punching. I am able to take many of it. I do show pian but do not whimper either. Yes, my balls get bruised and sore. Sometimes swelled. Ice helps and rest.
A man who gets kicked in the balls by a fully dressed woman while he's completely naked actually becomes a stronger man I think I'm stronger today for it./.
I used to know girl who used to do this./. I love being naked before having her kick me in the balls./. it actually got me hard./. It didn't hurt as much as I felt pleasure from it it hurts more now that it has stopped./. I long for this process to start up again./.
