"Mind control?" said Kita. "Just gross motor functions!" said Terra. "And we're not even sure it's going to do that, which is why we need a test." Kita can’t afford a flat on her own, and Terra and Gerana aren’t bad roommates. But there are disadvantages to living with a mad scientist and a mad entrepreneur. Like finding undead frogs in her shoes. Or when they want her help testing their latest product, and their latest product is a mind-control collar. Or when it turns out that Gerana has clearly spent a lot of time thinking about what she’d do to Kita with a mind-control collar. Or when it turns out that Kita really likes it . . .

Terra is a mad scientist. Gerana is a mad entrepreneur. Kita used to be their roommate, until they tested a mind control collar on her. Kita is happier as a pet and lab animal than she’s ever been, but Gerana and Terra still aren’t satisfied. Terra wants a mad science castle. Gerana wants her mind control collar back from the billionaire she sold it to. So they come up with a new product that they hope will make them an even bigger fortune: a belt designed to keep its wearer constantly on edge, without ever allowing her release. And Kita is there to test if for them. After a couple days with her new toy, Kita is totally focused on pleasure, and eager to be trained to serve Gerana, Terra, and their prospective buyer in any way they want. Until Gerana and Terra are satisfied, Kita won’t be—and they’re looking for a big payout.
