Education

Ryo is taken to a secluded villa by a man as payment for his father’s debts, where he is to be “educated.”
When he wakes, he finds himself naked on the bed.
Subjected to every kind of torment — a bumpy silicone finger-sleeve, a vibrator, a dildo, and relentless teasing of his nipples and perineum.
Overwhelmed, Ryo breaks into tears, and the man suddenly shifts, treating him with unexpected gentleness and declaring that the “education” will stop.
Given a small amount of freedom, Ryo stumbles upon an unlabelled DVD.
It was a recorded video showing how his father had sold him off, trading his debt and “something else” in the bargain.
—A prequel to the previously released “Education (Completed)”
