Hi Cyberdude,
Do you have any photos/movies of tied up testicles being sueeezed? I like to have my balls tied tight for a session as it stops the little beggers escaping. If mine get really scared they seem to withdraw and try and hide inside my body. A bit of rope soon stops that trick. Keep up the great work. This thread is WICKED!

PS. I have some tied testicle pics archived somewhere and I'll try and post a few soon.
