Walking sister in the street, or rather, the new OTASHINAMI of Yamato Nadeshiko! How about inserting a thick vibrator pen into the vagina and practicing erotic calligraphy!? The more you write, the more prize money you can get, but the pleasure is incredible! Once you climax, you can't write anymore, and you want money, so what should you do!? Hang in there, nine Yamato Nadeshikos!
