Serino, who has a strong desire to be mistreated, arrives once again for her training session. Even as every part of her body is tormented underfoot, even while restrained and unable to move, she continues to accept it all in pursuit of pleasure. Surrendering to her instincts, abandoning all reason, she does nothing but moan and serve. Devoid of human dignity, driven purely by animalistic urges, she remains motionless like a doll. At the end of this training awaits nothing but a beastly, burning lust.
