Suctioned Balls

Well lubed balls are submitted to a test fitting for new acrylic electro cuffs, by being suctioned into tight fitting glasses. Once they start in, they're squeezed smaller & longer until the whole ball pops in, squeezed very tight & very hard..
First trial was one ball per glass. Then both testicles were suctioned extremely hard till one, then both finally popped into one glass. One ball suctioned down tight & hard on top of the other one for an incredibly tight, fit, all around and top to bottom.. Cock dripping fun :-)
