A fake casting pitch asking office worker Yui Tenma to skip work unexpectedly lands a stunning beauty. Fresh from a breakup and still carrying an air of sadness, she enjoys a date and admits it is the first happy day she has had since leaving her boyfriend, then heads to a hotel. The better the sex feels, the more her masochistic nature emerges; even when treated harshly, she responds with an ecstatic face and gradually becomes obsessed with cock.
