おっぱいハート～彼女はケダモノ発情期ッ!?～
Ryuya lives a peaceful school life alongside his older sister Miya and his friends. This ordinary existence is shattered when the group accidentally consumes a strange medicinal juice. The concoction has an immediate and drastic effect on their bodies, particularly for the girls.
The drink induces a state of extreme sexual sensitivity and arousal. As a side effect, the girls' breasts begin to enlarge, and they are overcome by an intense heat that can only be quelled through sexual intercourse. Furthermore, the only way to create a cure, or vaccine, for this condition is for the affected girls to become pregnant. Faced with this bizarre crisis, Ryuya finds himself in the position of having to intimately assist the girls to both cool their urges and work towards a remedy.
