[ENG] [RJ405647] Boku ga Succubus to Eizoku Keiyakushite Sakusei sareru Ohanashi

This is the story of how I make a permanent contract with a succubus and get my semen milked. Our protagonist finds a book in a bookstore that claims to help you lose your virginity. Though he thinks it’s suspicious, he buys it, only to find that it contains nonsense. Infuriated, he decides to sell it at a flea market. However, in the middle of the night, he accidentally ejaculates all over it! The next morning, he’s woken up by the persistent doorbell, and when he reluctantly opens the front door, he sees a dark-skinned gal with horns standing there.
