Namaiki Lip
Synopsis
As a young, oral sex-enthused tutor makes his way to student Aki Kimishima's house, he thinks about how she's probably slacking off and reading manga again. Unsurprisingly, he hits the nail right on the head. This time however, their usually quiet lesson is flipped upside down when Aki asks him about his interest in oral sex. [Written by MAL Rewrite]
