Honnouteki Touka Koukan

Naoki, who dreams of taking over the family business and becoming a successful farmer, turns to his relative, Fujiyoshi, for help in paying off his family’s debts. Meanwhile, Fujiyoshi, a writer of erotic novels for men, feels he's in a rut and is looking to break new ground. Naoki’s arrival comes at just the right time. Together with Naoki, Fujiyoshi plunges into a world of eroticism he’s never experienced before, plotting to break out of his creative slump—but what will happen?!
