SDDE-437 Acme power generation: a restrained woman is kept in a continuous climax state as the company's power source

The video follows Mako, the woman who serves as the company's power source, kept in a state of continuous climax through restraint and machines. She is made to reach acme repeatedly with vibrators and male genitals, leading to mass squirting throughout the day. The endless loop of orgasms causes her to overheat, as the title suggests.
