The casting couldn’t be better in this sitcom parody, with Evan Stone in full hyperactive motor-mouth mode in the Robin Williams role and Chanel Preston sweetly appealing as his straight woman, Mindy. With the studio audience yukking it up over every innuendo—including a scene where Preston gives date Seth Gamble a champion hummer while they’re out parking after a date—it puts you right back there in the 1970s.

Retooled for porn, the plot involves Mork being sent from Ork to check out reports on a “second pussy” among human women. And he isn’t the only alien around. Robotic door-to-door dildo salesgirls Marie McCray and Tegan Summers are on their own mission of exploration, which involves putting their wares to work on Preston, as well as each other.

The first two scenes are solidly enjoyable, as is one involving Kagney Linn Karter as the head alien from Necrotron, who does the nasty with Tommy Pistol as the Fonz in a pop-culture mashup twist. But the best are, by far, Stone’s two scenes—and not just because of his usual athletic intensity, because his co-stars shine too.

As another alien, Nicki Blue is a foot fetishist’s dream, capable of stuffing her tootsies not only in her mouth but other orifices as well. She puts those limber limbs to good use in the rest of the scene, much of which has her standing spread-eagle while Stone hammers away.

Just as strong is the inevitable Mork-Mindy hookup, with plenty of oral examination of that “second pussy” (but, surprisingly, no anal). Stone stays clothed the whole time—in Mork’s tan chinos, long-sleeved T-shirt and signature rainbow suspenders—but that doesn’t get in the way of his licking, drilling and fingering Preston, who looks adorable both clothed and naked, from her big eyes peeking out from under her bangs to the pretty tattooed pussy beneath her miniskirt.
