Inkou Kyoushi 4 feat. Ero Giin-sensei - JK to Inkou Kyoushi 4

Hatsune is enjoying her vacation on a cruise. She was brought by Sensei, who she hasn’t had to herself for a while. Tolerating the embarrassment, she shows off her excellent body with a skimpy bikini that Sensei told her to put on. She is filled with joy after Sensei expressed his wish for her to make friends with those of her own age. On the other hand, there is the cheeky model magazine that makes her manager/teacher quell her body whenever she gets hot. She complains to him, but is easily coaxed into doing what he says… Simple as ever, Shizuka ends up meeting with Hatsune who has come to her school. Dumbfounded on how someone could look like a princess straight out of a story, Shizuka gets all buddy with Hatsune saying that she would love to meet her father who is a legislator. Thinking to herself that using her weapons as a high school girl would be more than enough for some legislator…
