Iino and Ishigami "Protecting School Morals" (Kaguya-sama wa Kokurasetai) [Full Color]

Strict morals enforcer Miko Iino catches Ishigami with an erection at school and decides the only way to protect public decency is to handle it herself — swallowing him deep before bending over so he can pound her from behind, pantyhose stretched around her thighs while she insists it's purely disciplinary. Just as she finally breaks and admits how badly she's wanted him all along, a bespectacled classmate stumbles onto the whole corrupting lesson. Then Ishigami jolts awake in his own bed, horrified that his fantasy played out like a cheap doujin — and that he now has to survive student council with his 'morals' barely under control.
