If He Doesn’t Get Pregnant in a Month, He Turns Back to a Man (4)

Synopsis

Himemiya, the protagonist, was transformed into a female body by a strange illness. He has one month to turn back into a man—but only if he doesn’t get pregnant. Her female body feels too good, and before long she’s enjoying raw sex with the entire class as if it were the most natural thing. But will he really be able to turn back into a man?

In volume 4, the male classmates take a trip to the beach and spend the entire night having sex at an inn.
