Rock Hard is an erotic tour of masturbation vignettes featuring seven well-built studs. This 1987 John Summers production, co-directed by Summers and John Travis (of Brentwood) and subtitled The Ultimate Masturbation Experience, provides horny dirty-talking narration from the models over its sizzling solo scenes with loose stylized settings (gym, office, bathtub) and themes (mirror jack off, a show put on for a bedroom-peeping voyeur). The film features shaft-stroking, exhibitionism, and displays of attractive (and often very muscular) bodies abound, plus a little fingering and a dash of kinkiness with handcuffs, light self-bondage, and self-spanking. This well thought out and attractively produced series of vignettes is a sexy stunner for fans of narrated solo tapes in the vein of Summers' Young Gladiators. Cast: Leigh Erickson (aka Marc Bennett), Jason Lowe, Eric Radford, Vinnie Marino (aka Drake Horton), Joe Gibbons, Bill Bix (Falcon's Mystery Skier), Alan Fox
