DANDYA-010 - A glimpse of a student's developing breasts causes sexual arousal and inability to control an erection. A submissive male teacher, in dismay, immediately exposes himself and engages in sexual activity.

A male teacher, aroused by a chance exposure of a student's breasts, pleaded for fellatio, and unexpectedly received consent. Unable to resist while watching the student diligently perform oral sex, he ejaculated. Saying "This is also part of the lesson," he finally received pleasure from a small, sensitive penis and ejaculated on the student's cute face.
