A girl becomes a pupil in calligraphy school that is famous for it's spartan education. Kaoru Fujisaki is the female college student who is very pretty in her traditional school uniform. She is a serious student and so an honorary master - a living national treasure - deals with her direct guidance. She is surprised at the appearance of the master who teaches stark-naked. Yes, this master does not use the brush but the cock instead! First they start with rubbing an ink stick. However, Kaoru is undressed and finger fuck is made. The large amount of joy juice sprouting out of her pussy is collected in the ink stone. It seems that in this classroom joy juice is used instead of water to mix ink. Then Kaoru's nipple and pussy is stimulated with a writing brush. Next a cock is prepared and she is shown how to grip the cock and slip it into her mouth. The writing brush can be handled only after the cock is handled well. It is original master's calligraphy theory. Of course the integration of the pussy and the cock is the most important part of this theory. And then cock is inserted at backward woman on top posture. The sight of a cock sticking deeply into a delicate woman's body at woman on top, back and bending posture is a masterpiece. Then, vaginal cum shot creampie is made at missionary posture. A lovely piece of pussy calligraphy is well displayed.
