[Seza Team (sezan)] ENA ISM (Yotsubato!) [ScanMTL]

ENA ISM features Ayase-san, a black-haired girl, in explicit scenarios. The cover shows her swimming underwater. Inside, she reacts with surprise to a boy's size and later tastes bitter semen. Later, she is shown tingling and arguing about turns while being intimate. In a classroom during summer break, she engages in sex with a boy while others watch, noting she will lose her virginity too. The author's afterword explains the trope of a girl who cannot refuse and ends up in an orgy, highlighting themes of reluctant submission and physical sensation.
