Mei-chan wa Aware na Kohitsuji

A sheep beast person was ravaged by the mercenary that raised him. He has continued to lust after his body since that very day... A magician and a swordsman, May, a sheep beast person, and Zephyr, a mercenary and May's foster parent, party together. Compared to Zephyr's incredible abilities as a swordsman, May's lack of ability causes him endless worries. Zephyr lusts after May's body day after day, to such an extreme degree that May starts to wonder if that's the only reason he's in this party... Love exists between them, but as it's not communicated, you're left feeling sorry for May from start to finish.
