1x28 - Hello! Spank

Spank and Aiko met a strange grandfather on the street. He wants to sculpt a spank as a model. Two people who became creepy. When I finally shook it off and went home, the grandfather said that he was Fujinami's teacher. Finally, Spank, who can't refuse, takes on the model. At first, it was rare and I even felt fun - but this teacher will never allow me to move. Besides, it seems that they will do all night on the 4th and 5th. The frightened Spank tries to escape, but his assistant gets in the way and gets tied to a chain. Spank who doesn't go through meals due to lack of exercise and lack of sleep. I managed to call for help on the phone...
