Amai Ijiwaru

Synopsis: Rina is a reserved and submissive girl, whose presence is so weak it's barely noticeable. She has no friends apart from Kotori. Sometimes, when her phone rings, she will sneak out of the classroom. However, she maintains a friendly and easy-going relationship with Kotori. Rina appears before Naoto, Kotori's father, lifting her shirt to reveal her small, adorable breasts in a state of semi-nude. Naoto can only stare at her in astonishment... "Don't worry, I won't tell Kotori anything." In her hand, Rina holds a phone with recordings of herself during their sexual encounters on paid dates... With those words, Naoto has no choice but to give in to her advances.
