In a scientific establishment, a new form of android called the "Sexaroid" was created. The Sexaroid was created to be like the ultimate "living" sex toy, and the new male half-human, half-animal model is sure to be a success, though still in the testing phase. The first two prototypes were Shiro, a cat-boy Sexaroid, and Kuro, a dog-boy Sexaroid, created by the Doctor with help from his assistant, Kashiwagi. Before they can be put on the market, the Doctor decides to test them himself, to see if they can be made into subserviant sex slaves. To get the data needed, he needed a human to compare the results with, and he turned to Kashiwagi, who firmly refused the offer, even when the Doctor offered to double his pay to be the guinea pig for the testing. Not taking no for an answer, the Doctor knocked Kashiwagi out with an anesthetic and restrained him, and is now using him in his studies. His first client wants a Sexaroid in two months, which the Doctor finds sufficient to do his testing. For the next sixty days, he will find out exactly what the Sexaroids are capable of.
