Hybrid Stardust

"Hey, old man, if you plan to die then at least have sex with me first." Taizo Yakyo is a middle-aged man who's drowning in debt and loathes the world around him. All of a sudden, a handsome young man named Kiyoto appears before him. Kiyoto reaches out and says, "Your body, old man, is too lovely to waste." Taizo accepts the young man's invitation, but... Taizo is then taken to a huge mansion, where he finds out Kiyoto's the heir to a famous and wealthy business conglomerate! Kiyoto then forcibly straddles Taizo, saying, "I'll make all your debts go away, so from now on, you're gonna screw me whenever I want, OK?" ...!? This is a rags-to-riches-style love story between a middle-aged man who's hit rock bottom and a bossy, spoiled brat!
