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...

Tina has her date with Allie and spreads the milk. Dana gets the heat again, and Allie happily succumbs to it when she visits after escort duties. Maddie and Leila play house with adult baby Ruth. Jenny and Hoshi visit a 'pet-friendly' BDSM club but find it isn't quite what they're looking for. Kara edges toward cowdom, in a behavioral sense.

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.

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

Maddie gets involved with her mom and sister's sex games, while Leila starts succumbing to a blackmail attempt by their milky boss Tina. Maddie falls into the trap, too, but turns out to be a bit more clever and ruthless than Tina expected. Their victory celebration is sweet, but results in Leila unwittingly using the device on Maddie while she sleeps.
