IPZZ-296 The serious and quiet librarian, Akari-san, was actually a severely twisted sadistic pervert... Tsugumi Akari.

The usually serious and quiet librarian Akari has an unbelievable secret... A gentle beauty transforms into a wild woman, playing with the shriveled dick of a middle-aged man until he's dry of cum! What if you get caught because you made noise? Is that okay? In a situation where you can't make a sound, your dick is exposed, jerked off, and sucked, leading to forced shameful ejaculation! Making sounds like a little girl, so cute. Whispers that stir up shame and intellectual dirty talk. The masochistic tendencies of the middle-aged man are developed. The ultimate pleasure of being humiliated and made to submit by a gentle beauty, becoming a dick slave. Do you hate it? If you do, we can stop anytime...
