Description: Most pumpers (as vacuum enthusiasts are known) are used to low intensity hand-pump devices or modestly powered suction machines. You put these on your dick and balls and watch them swell up to amazing proportions, often for hours at a time..uh, we mean some people do. We use vacuum in this tape as punishment – heavy punishment. You wouldn't dare use the levels of vacuum that we used for hours at a time the tissues just wouldn't take it. There is a special kind of masochist who is fascinated with medical technology and hurtful "procedures." Even when the hurt gets unbearably intense you will see them with huge erections. Warning! In its way this feature is every bit as explosive as Kickball I and II. After Andrew Montano and Michael Evans are "sucked off", there is some exquisite C-clamp individual testicle crushing and explosive shocks from a hand-crank field telephone generator.
