Koibito wa Hatsujouki

Kiyoharu, friendless and without a family, owns a single dog, Jirou. The dog, which miraculously turned into a human six months ago, went into heat and ravaged his master~\\\"Jiro, I love you very much - but it troubles me to have you make love to me so deeply.\\\" As Kiyoharu becomes deeply troubled, Jirou goes into heat yet again!
