FSDSS-629 Ami Tokita is kept under house arrest by the abnormally sexual-minded uncle next door and is constantly forced to cum.

An old man lives in the next room, and no matter how many times I warn him, he won't clean up the huge amount of trash that overflows into the hallway. When they happen to be cleaning together, Ami gets on all fours and sees the panties that are visible through her skirt, so he gets horny and puts his hands on her. He persuades Ami, who still doesn't have much knowledge about sex, and unleashes his pent-up abnormal sexual desire. I'll take you home when you're done, he said.
