There lives an uncle in the next room who never cleans up the massive amount of trash overflowing into the hallway, no matter how many times he's been warned. One day, while cleaning together, he becomes aroused by the panties visible from Ami's skirt as she crawls on all fours and makes a move on her. With Ami still lacking in sexual knowledge, he manipulates her, unleashing his abnormal sexual desires. 'I'll let you go after we're done,' he says, yet every time Ami wakes up, he thrusts his erect middle-aged penis into her young body, driving her to the peak of ecstasy over and over again.
