Shiho, a former female teacher, teaches calligraphy to her former students while giving sex lessons. Instructing Haruo to deep sex, stimulating cock with a brush at Takashi's wish, going crazy with lewd slut play, and receiving caress with naked calligraphy at Shinji's request. Shiho is now my turn and 3P, restraint, vibrator, and rotor are disturbed as much as lust.
