Karen and her boyfriend have been in love for a while. Today she went to the apartment he had just moved into. Her boyfriend gave Karen the house key, and they both imagined a happy future together. However, continuous sounds of sexual activity came from the next room. The foul smell from the long-overdue trash bags made it hard for them to breathe. Karen's boyfriend went over to remind the old man in the next room to turn down the TV and take out the trash, but he seemed to ignore it and became extremely unpleasant. The next day, Karen went to prepare dinner for her boyfriend. But at that moment, sounds of a sex movie came from the room next door. When Karen went to remind him, the old man pulled her into the room and forcefully took her body! Karen's strength was no match for the powerful man, and she could only watch as he invaded her and planted his seed inside her. From then on, every time she finished cooking for her boyfriend, she was called over to be fucked by him. Karen's boyfriend heard but thought the old man was watching some sex movie. And time passed.

And soon, Karen became pregnant, and her boyfriend, unaware of everything, took responsibility for her, helping the dirty neighbor next door...
