Sister x Lecture
シスター×レクチャー
A young man is recruited to provide a very private form of education to two celebrity sisters. The sisters, famous for their public image, are completely inexperienced in the art of cunnilingus. He becomes their secret instructor, tasked with giving them monthly lessons in this intimate act.
What begins as a straightforward arrangement soon grows complicated. The lessons take place behind closed doors, hidden from the world. As the sessions continue, the strict roles of teacher and student begin to fade. The sisters discover new sensations, and the instructor finds himself drawn deeper into their world. The boundaries of their relationship start to blur, leading to unexpected and passionate entanglements that go far beyond the original lessons.
