I recently reread this manga, and really liked the fourth story about the sensei Yukijima getting boinked at the lake by lusty student Uraga. I don't understand the student's mentality regarding the teacher remembering his name, how does that give him reason to seduce the teacher? BTW was the sensei a virgin prior to the sex? Regarding the one with the samurai prisoner and British navy, those navy officials were a bunch of pervs, I felt sorry for the guy.
