Milo's manga / #MC is horse(1)

Complet - 6 chapitres I clearly forgot this manga icky point. Somnophilia (seme keeps going after uke fainted, gross), weird power play/obedience training, prove you love me by giving me a bj (wtf ?!), barely allow him to say goodby to his horse mom and friends. A thirty-year-old Japanese male is teleported to Japan's warring-era. But instead of being reincarnated as a samurai or ninja, he is now a pony! Cute and spry, he is enjoying is carefree new life but all that changes when he runs into a human who is fighting off a bear attack! The pony dashes and rescues the man, and thus begins his new life...as a warhorse!
