Merman in My Tub Vol. 2
This book would be a lot better without the little sister. Honestly it's gross the way she always wants to take a bath with her "onii-chan" and there's always a panel of him feeding her something phallic with her going "Onii-chan it's too big." with all the sexual implications coming from that. Her eyes with tears in them and blushing. Typical moe hentai shot.Also Maki doesn't get enough love.
