After her mother and newlywed husband died, Riri Nakayama was left alone. Hoping to at least meet her father, who disappeared when she was a child, she masturbates hungrily in the apartment she moved to. When the manager comes to tell her that her moans are too loud, she uses her beautiful pantyhosed legs to lure him out of danger by giving him a footjob. When a stranger breaks into her room, he tells her that she's run away, so she comforts him with a creampie. Meanwhile, Riri happens to be reunited with her long-lost father, who lives in the same apartment building, and she seeks out his cock, climaxing with joy as he showers her with incestuous semen!
