START658 hands the classroom over to Mana Sakura as the female instructor, and the curriculum is humiliation.

This is a lecture on holding back ejaculation, aimed squarely at men who have given up on real sex and survive on masturbation alone — and Mana looks down on every one of them while she teaches.

She rejects, she taunts, she corrects, and she never lets the student forget how far behind he has fallen.

The format is instructional in name only; the real engine is the power imbalance, with Mana Sakura in full domineering instructor mode, pacing the lesson so each failed hold earns another round of mockery.

If the appeal of a strict female teacher who treats masturbation as a character flaw is your thing, START658 is built exactly for that.

It is a solo-work showcase for Mana Sakura, and she carries the whole runtime with a mix of condescension and clinical control that makes the eventual release feel earned.

Sit down, take the lecture, and try not to break early.
