Sensei Shokushin shite Kudasai!

"Have you ever been to a backdoor sexual entertainment place?" Because of a brief comment made by his kouhai, the pleasure-loving Saeki teases his own butt. However, the battery he thrust inside got stuck!? He rushed to the hospital and was treated by a gastroenterologist, Kirishima-sensei. When he consulted him about the location of his prostate, he used his finger and explained it hands on... which felt crazy good? "Would you put your dick inside...?" The cool technician doctor and the sex loving straight man's sex love story that started with treatment!
