Today I once again lay on the medical bed for treating cervical spondylosis. Just like before, I fixed my hands, feet, knees, waist, and chest with ropes, and fixed my head with a medical mask.

then my girlfriend turned the rollers and stretched the bed until I was lying flat on my back, unable to move at all.

The extra props added today are two clamps.Each clamp was attached to a thin wire that wrapped around my big toe. The clamps hurt a lot when they were on my nipples, but the bigger pain was when the string tightened and if I didn't flex my toes hard it would pull on the clamps which would cause even more pain to the nipples.

I didn't last long in this huge pain. My girlfriend's foot touched my cock a few times and I let it out.

I think it was the pain in my nipples that gave me more intense stimulation. This is why men need nipples too.

It's not a decoration any more.hahaha.

ps:My girlfriend refuses me to use the clamp on her, is there any way I can convince her? .
