Ai wo Ataeru Kemono-tachi

40 year-old doctor Chikayuki Shinra suddenly finds himself de-aged and transported to Fenewald, a medieval world of magic and animal-shifting beastmen. Captured by bandits and sold into slavery, Chika has a curse placed on him and spends the next few years suffering from extreme abuse. Salvation comes unexpectedly one day when he is rescued by Gail, a bear shifter with a crippled leg, and Douglas, a lion shifter who is missing an arm. The wounded warriors lovingly nurse the battered Chika back to health and life finally begins to feel hopeful again as the three men find joy in what soon becomes a tender three-way marriage. Chika wants to put his medical knowledge to use helping people in this new world, including the men he loves, but there's still the matter of his curse to deal with. In order to break it, he'll need to... have a baby?!
