Cassie uses the remote and Salalai and gives the girl a mesmerizing pussy, while Maddie tries to come clean with the pet girls and explain matters, to mixed results. Kara, Kat, and Hoshi work through their feelings about the revelations, but their animal instincts ultimately rule the day. Maddie and her family finally locate a user's manual of sorts, which makes them aware of what's to come. Dana transforms in a park and sets off an orgy, and Cassie finds herself doggishly submitting to Sally.

Tina and Ruth bond, while Hoshi and Kara ponder petdom while visiting Jenny and Allie, who are making plans for a petgirl orgy. Dana freaks out after returning to her human form and flees with Miguel, while Cassie humbles herself to Maddie in exchange for borrowing the device. None of them realize that fourth level traits happen automatically, and Maddie gets a new kink while she sleeps.

Allie accidentally lets slip that she and Jenny are related around Hoshi, which causes some strain on their sexy times. Tina starts thinking about ways to monetize her milk, but Maddie has her own plans for the would-be dominant woman involving their adult baby Ruth. Cassie and her friends finally ambush Leila and Maddie afterwards, but it doesn't work out exactly as planned. Instead, Dana and Miguel get zapped again; he gets magical sexual endurance, and she gets turned into a weredog...

Many of the characters come to decision points about where they want their lives to lead. Cassie tries to explain the device to Miguel and Dana, recruiting them against Leila, but before the confrontation can happen she winds up fucking a teammate. Maddie has a taste of public humiliation, but it helps her come to terms with her mental dilemma, and she devises a plan.

Maddie starts to realize that some traits seem contagious. Tina gets zapped again, making her lactation spreadable as well. Maddie and Leila decide to ditch school for a few days to figure things out, but a new function of the device reveals itself, and Leila winds up zapping an old bully of theirs, who they chance to meet on their mini-vacation. Meanwhile, Cassie starts putting the pieces together, but wrongly, while Dana and Miguel have issues at home thanks to their new nudism.

Maddie, Leila, and Cassie engage in a petplay threesome, after which Cassie gets a more advanced form of nudism. Meanwhile, Jenny, Allie, and Hoshi are having a lesbian pet threesome of their own, and spreading their fetishes to the puppy girl. The following day sees Cassie finding the device, but making the same mistake as Leila did, uses it on her friends Dana and Miguel, bringing them into the fold.

Cassie goes permanently nude, Maddie trances her girlfriend and her sister, and Jenny has a petplay date.

Maddie turns her roommate Cassie into a nudist (who then seduces some classmates), turns her boss into a lactating breastmilk fetishist, and turns her girlfriend into even more of a bunny.
