[Sago-Jou (Seura Isago)] Ishigami Yuu wa Iyasaretai (Kaguya-sama wa Kokurasetai) [Colorized]

Ishigami finds himself increasingly overwhelmed and flustered by Chika's cheerful obliviousness as she discovers his excitement and eagerly takes charge to "help" him. With her soft, pillowy breasts pressed against him and her wide-eyed enthusiasm, she pulls him into deeply intimate positions, moaning about how huge and different everything feels inside her. The story climaxes with a flood of cum that sends her into a euphoric trance, leaving a mentally shattered Ishigami in his bed, questioning how his Christmas Eve spiraled so spectacularly out of his control.
