Anata no Milk Kudasai na ~Watashi to Boku to Docchi ga Okonomi?~

Sakurai Manato was a young man with a peculiar sexual quirk: due to past experiences, he could only feel arousal toward girls with underdeveloped bodies.
One day, a succubus named Teana—a buxom older-sister type—showed up at his doorstep.

“I need your help! Can you help me overcome my… sexual quirk?!”

Manato believed that with the techniques of a succubus, he could finally return to being a normal human.
He pinned his faint hopes on this chance encounter.

Teana wanted Manato’s semen, and Manato wanted to use his encounters with Teana to become a normal man again.
But then, another succubus entered the picture—Alicia, whose modest body was her selling point.
Both succubuses wanted Manato’s semen, and both used their bodies to tempt him…!
Could Manato overcome his sexual quirk and return to being a normal human…?
