Boku ni Harem Sefure ga Dekita Riyuu 1

In class, three girls were mesmerized by the perverted Nanashi! Without any female immune system, Nanashi is tormented by the carefree and unconscious girls. The three girls forcefully show up at Nanashi's house...? Nanashi, who is tricked by the girls' gossip, ends up completely immersed in their conversation, which gradually turns into an explicit flow... "I want to try it too!" Nanashi's excitement explodes, and the girls, starting with 4P, lead her into a self-indulgent experience, both body and mind sinking.
