[ Animation Sex ]Stringendo: Angel-tachi no Private Lesson 2

Based on the manga series by Seto Yuuki. Tomohisa and Endou aren't particularly attractive or unattractive; they are simply ordinary high school boys. They're staring at Mizuho, the older student, and Mikura, a classmate. Mizuho is a returnee student who draws the attention of all the other students with her attractiveness. Mizuho detects their gaze and offers Tomohisa a provocative glance. Tomohisa discovers a message on his desk one day. It reads, I'm waiting in the ladies' room on the third floor. He arrives to the location and finds Mizuho waiting for him... The following day, Tomohisa can't stop thinking about what happened the day before. He is surprised to see that Endou has vanished, as well as Mikura, whom he has a hidden crush on. He is concerned about what they are doing. Exactly what they're doing on the fire escape is a mystery to me.
