In “Buttman Toy Master,” pioneering pornographer John Stagliano guides natural-bodied, lustful adventurers through body- and soul-baring exercises with his arsenal of orgasmic implements and wicked fetish gear. The director’s signature camera work — and mirrors — present over six hours of arousing intimacy. Dark-eyed, scratchy-voiced stunner Abella Danger’s stretch pants, thong and fishnets show her amazing ass and bald twat — Buttman plumbs the depth of her crack with his nose and Abella spreads, flexes and winks her pretty asshole. A medieval nipple stretching apparatus tests her tolerance. Tiny-waisted Chicago girl Gabriella Paltrova works out with weighted labial clamps and a metal speculum. She blows slobber bubbles as she sucks dildos; she queefs and quivers in “ass-gasm.” And Gaby crams two huge chrome balls in and out of her cratering rectum. Buttman torments auburn-haired cutie Maddy O’Reilly’s nipples with nasty suction devices, one of which makes her clit throb visibly. Maddy’s naked cheeks clap as she twerks. In a striking shot, fair-skinned, trim Jodi Taylor fucks a dildo mounted to a mirror. A toy makes her anus gape colossally and she sucks phallus ass-to-mouth.
