Responding to a request to train Ai, the cute yet non-sexual girlfriend, the scene unfolds with play designed to draw out her pure nature. With both hands restrained, she is penetrated from behind by a large cock, her hair pulled as she is thrust into from behind while standing. Matching her movements, they move to the bed and switch to cowgirl position, enjoying the sight of her swinging her hips and cumming. During this, she is pounded hard from below, made to cum repeatedly. While being taken doggystyle, she is ordered to say "sorry," waiting for her to whisper those words. After receiving intense deep thrusts, she honestly says, "I'm sorry I came," a reaction that is thoroughly enjoyed. In an unconventional doggystyle position, she is intensely piston-fucked deep inside, making Ai moan, "My pussy is going to break, but don't stop. I want you to destroy me," as she is brought to climax. Afterwards, she is made to cum repeatedly in missionary position, finally receiving a forceful pounding while being choked, as she pleads, "Give me lots," and is filled with cum shot into her mouth.
