Kemono wa Okumade Aisaretai
I remember reading this! There's 6 chapters + 1 bonus — Definitely not for people who don’t like naive, “damsel-in-distress” type ukes… Poor Haku has to adjust to his life as a pet for Eiichi while Eiichi has to deal with Haku's desire to please and reciprocate. When Eiichi ends up having sex with Haku during his heat, he finds out after that Haku has no idea what sex even is, and Eiichi refuses to do it again. Unfortunately, Eiichi gets blackmailed into an engagement with a woman who threatens to expose his "like for beasts". She goes as far as scaring Haku out of the house, making Haku believe that he can sell himself for the sake of Eiichi. Haku goes to the men who were after him previously, asking to be sold at a high price so that the money can go to Eiichi. They agree and also reveal the truth about Haku's farther. They then take Haku to an auction, where people quickly begin bidding on "the rare species". Luckily, Eiichi comes to save him since his butler had heard the woman threatening Haku. Eiichi finally confesses to Haku. Overjoyed Haku accepts and when they get home, Haku begins masturbating in excitement for Eiichi, leaving Eiichi confused since Haku isn't in heat. Haku reveals it's because he loves Eiichi and wishes to have sex with him, and Eiichi finally makes love to him.
