Akari, a normally serious and quiet librarian, has a shocking secret... A quiet beauty suddenly changes... She plays with the withered cock of a middle-aged man, devouring him until he runs out of sperm! If you make a sound, you'll be found out, right? Are you sure? In a situation where you can't make a sound, your cock is exposed, stroked, sucked, and you are forced to ejaculate in shame! She has a cute girly voice. A whisper of intellectual dirty talk that stirs up shame. The masochistic nature of a middle-aged man is developed. The ultimate pleasure of being humiliated, submitted to, and made into a cock slave by a gentle beauty. Do you not like it? If you don't like it, you can stop...?
