Arui wa Koi to Iu Na no Mahō

Arui wa Koi to Iu Na no Mahō is a Japanese adult romance visual novel with fantasy elements. The player takes on the role of Yamato Ibushi, an ordinary man who is living an ordinary life until he is approached by three beautiful princesses: Fatishion Swallow, Lianfest Scale, and Cereaneeg Crown. The trio claim to come from another world which is facing a crisis which they need more magical power to overcome, and fortunately, Yamato's semen possesses special properties which would greatly increase their powers. Unfortunately, Yamato can only choose one princess as his partner, and each has a problem preventing them from being perfect wife material: Faty turns into a bird when she falls asleep, Lian suppresses her feelings to avoid developing a fever when angry, and Cerea cannot convey her feelings in words.
