Kinky director Aiden Starr presents fearless fetish submissives getting off the hard way in “Masochistic Masturbation.” Tall African-American stunner Skin Diamond is bound to a chair in a metal collar. Wicked suction devices distend her pink nipples. Electric pulses shock her clit, tongue and butthole, causing intense, staccato squeals. Asian-American Mia Li has C-U-N-T lipsticked over her tits and a fluffy animal tail butt plug inserted. Metal nipple clips indent her areolae, electrodes zap her thighs and Mia buzzes off with a plug-in wand, electrodes and butt plug still in place! Spunky Kristina Rose drools around a ball gag and flogs her own ass. A metal tube in her bunghole sustains musical tones when struck, and Kristina drags a spiked pinwheel over tongue, clit and labia. Leggy Kimberly Kane has a bit harnessed to her mouth before donning a horse head. Aiden canes her feet. Kim smacks her own labia and nipples with a strap, and multiple clothespins dig into her lips and boobs. Aiden Starr’s “Masochistic Masturbation” is a single-disc DVD with behind-the-scenes footage, photo galleries, cast list, filmographies and trailers.
