Makutsu No Ou ~Yomei Ikkagetsu No Doutei, Mahou Shoujo Harem O Kizuite Ou E Kunrinsu~

Shimizu Shouichi finds himself suddenly thrown into a strange, monster-infested forest in another world. His life is saved by a charming fairy named Ami, who grants him the abilities needed to survive in this dangerous realm. However, there’s a catch—he must bring a girl to climax at least once every month, or he will perish. As a socially awkward virgin, Shouichi struggles with the idea at first. Yet Ami’s persuasive words slowly break down his resistance, revealing the hidden desires he’s kept buried deep inside. With his life on the line, he must navigate the challenges of intimacy with magical girls. What follows is the unlikely journey of a shy, inexperienced young man and a fairy with an unusual fixation on doggy-style antics. Will Shouichi overcome his fears and fulfill his bizarre condition, or will his inexperience lead to his doom? The stakes are high, and time is running out.
