Tachi Neko Soudatsu BL
V.1 Ch.9: Elite host club alphas. One works very hard and is very serious about doing a good and respectful job with their omega clients. The other is a natural at being a host and makes customers feel special by acting on instincts alone. The serious one thinks the other is too flippant. But the other one is in love with and admires him so he gets a female client to book them both and then she instructs them to have sex together. V.1 Ch.6: Two men vying for top position in sex. Very short. Maybe historical. One seems to be a playboy. The other is perhaps a little possessive.
