Yoiko no Gohoubi♥

A young boy named Yuuji is a model student who always follows the rules and gets good grades. His mother rewards him with a special treat for his excellent behavior. However, this reward takes an unexpected turn when his mother introduces him to a new form of "discipline" that blurs the lines between punishment and pleasure. As Yuuji navigates this confusing new dynamic, he finds himself drawn into a world of taboo desires and forbidden encounters.
