Conspiracy of Doctor Busujima

Doctor Busujima turned 90 years old, but he did not want to die. He wished to live forever. The doctor found a married couple perfectly suited for the experiment and infected the husband with a virus. Soon he contacted the wife and offered her to resurrect her husband in exchange for sex with her. She, of course, agrees, and after using a special device, the soul of Doctor Busujima himself enters her husband's body... 

In general, a rather strange, surreal and delusional story...
