Manga otaku Tatsuya used to get excited only by the amazing busty women that appear in erotic comics, but because of work, he came back from overseas after a long time, and his aunt Natsuko's erotic comics surpassed them. I get an erection when I see an erotic boob. Moreover, Natsuko was a lewd woman on the inside who taught Tatsuya how to peel the skin and how to masturbate when Tatsuya was little.
