A string of climax-craving chicks arrive at the lair of the "Thrill Hammer". The rhetorical motivation: These women are here to redeem their free vouchers entitling them to an "orgasm." This fun framing device sets the stage for the aforementioned jerry-rigged contraption to work its magic.

The oil-drill pulse and dentist chair motif of the device makes it far from erotic, but orgasmic bliss is uniformly achieved. The fresh-faced cast retains a naïve charm, but the scenes are monochromatic. Still, that G-spot probing mechanism gives any sybian a run for its money. A bonus scene is an unrelated straight boy/girl amateur romp.
