Getting back at a braggard asinine ex, a man invokes a spell that turns an alpha dom into a needy jock, donking out in the process. Perhaps, however, he takes too much fun in the man's descent into donkeydom...

The final chapter, wherein Maddie finds out Leila's pregnancy is kind of hyper, and might take as little as 8 weeks. Dana tries to cope with her transformation to a weredog, but by moonrise she's entirely sheepdog. Cassie agrees to Sally's plan to seduce more of their teammates, if only to distract the girl from continuing to dominate her with petplay. And then, Leila's animalistic features spread to the other women she's slept with when her fourth trait triggers.

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.

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 and Leila have a threesome with Cassie, and then they go and meet Jenny, who is more catty than ever after a third zap from the device. The three test out her new power by having public petplay sex in a nearby park. Meanwhile, Allie is interviewing for a job as a high-class escort, and dragging Katrina into whoredom with her. She and her mom share some fun afterwards, and she really embraces her role as AllieCat.
