[Niui] High on Love (Gotoubun no Hanayome) [Full Color] [The NekoMancers]

Nino Nakano's carefully guarded composure crumbles when a drug unleashes desires she can no longer deny—submitting her entire body to Uesugi-kun in a haze of heat and humiliation she secretly craves. As she loses herself in the moment, a drawing of her sister Yotsuba held over her flushed face hints at a deeper fixation, and the thought of convincing the ribbon-wearing sister to join them lingers in the air. What begins as one sister's drugged confession of lust spirals toward a taboo tangle of quintuplet intimacy neither twin can walk away from.
