We start off with Professor Wyzinski (Jon O'Brien) at University College pissed off that Professor Carol Lash (Chandra Sweet) won't fund his robotics project, which unknown to him, has possessed and tortured his wife and neighbor. He begs Chandra to check out his work in person. Professor Lash's assistant Pamela (Amy Van Allen) tags along.

Meanwhile, in the garage ...

Neighbor Kimberly (Penelope Pace) has a big red ballgag in her mouth, her ample breasts are bound in rope, and she is sporting a nasty-looking black strap-on dildo. The professor's wife (Lisa Kinkaid), who is topless and frogtied with ropes, is forced to give the dildo some head. She gags repeatedly on the dildo while Penelope gags on her ballgag.

With a cleavegag back where it belongs, Lisa, on her back, is violated by Penelope while the machine, named Ed, gets off by moving its arms. Lisa does some nice screaming through the gag while Penelope pumps away.

Chandra, wearing a white blouse, black pants and glasses, and Amy, in a tight sleeveless red top and tight skirt, check out the machine in the garage, where Lisa and the neighbor have mysteriously disappeared.

Chandra and Amy giggle at the phallic nature of some of Ed's parts. After Amy heads out to get some papers, Chandra takes a closer look. Ed comes alive, clamps her hands and shoves the dildo thing in her mouth as an effective gag. The professor eventually passes out.

Ed moves in and removes Chandra's clothes. She comes to but wires are wrapped around her legs so she can't escape. Another wire goes up her butt that puts her under the control of the brain. Amy returns to the garage, and says what anyone would say if they saw their uptight female boss naked, squatting on the floor and giving head to a piece of rubber sticking out of a machine: "Professor Lash, what are you doing?"

Chandra, with a lovely psychotic look in her eyes, attacks her assistant forces her to give some "machine head" while playing with her tits from behind.

Amy passes out and Chandra, on the orders of the talking brain, gets Amy naked to her black garter belt and stockings and gives her a literal tongue lashing. The professor ties Amy's hands behind her back with her panties, gives her tight ass a few swats and plays with her some more.

We flash back to four years ago, and we find Amy, looking damn hot in an incredibly tight and short orange skirt, being attacked in a garage.

The maniac (Bryan Dunhill) tears off her panties and forces her to blow a dildo sticking up from a chair. He verbally abuses her, but she's feisty, calling him a son of a bitch and telling him to go to hell. She is forced to sit on the dildo, and the villain compares it to a ride at Disneyworld.

A bit more goofy dialogue ensues, and the villain shoves Amy's white panties in her mouth and keeps it in place with a swatch of yellow tape. He then ties her with rope and puts mousetraps on her nipples and clothespins on her pussy lips. He fondles her, smacks her pussy a bit and taunts her while giggling like a nutter.

But a cop interrupts the fun and shoots the maniac. We find out that Amy was attacked by the now-deceased Workshop Killer.

We return to the garage with Chandra spanking Amy. On the orders of Ed, Chandra ballgags Amy, who is bent over with her wrists secured by the machine. She gets dildo fucked from behind by Ed and makes some good grunting sounds, although the dildo isn't really moving. Chandra fondles her tits and pulls her long hair aside so we can see her ballgagged face.

The ballgag is removed and Amy has to blow the machine. Ed's sperm spills out and a puddle of spunk forms.

Ed speaks and tells Amy that he is the brain of the Workshop Killer.

"You're evil!"

"Yes, and loving it!"

Next Amy is hogtied and tape gagged. Chandra licks her all over before sitting on the floor to masturbate. The tape is removed so Amy can eat out Chandra, who cackles.

Amy is now tied AOH with a big ball shoved on her mouth and held in place by a white strap. Chandra puts clothespins on Amy's nipples, spanks her and tastes her pussy, much to the delight of Ed.

Jon arrives and we find our what happened to Penelope. She's now a bloody piece of meat hanging from the ceiling. Jon decides to destroy the machine, but Ed talks him out of it. After all, he controls Professor Lash, who is in charge of funding. Ed also promises Jon immortality and fame. Oh, and he's got wife Lisa hidden away as an insurance policy. Jon, after a drawn-out dialogue, decides to grant Ed's wish and make him a body.

The movie ends with Chandra taking orders to spank Amy some more.

Although Cold Metal is mostly girl/girl action, it had its moments. Chandra Sweet plays a great psycho, and Bryan Dunhill is, as always, dependable as a nutcase. And Amy Van Allen has always been my favorite victim.

The scenes themselves were OK, but like the first movie, the ones with machine were lukewarm at best.
