Instructor Yaya-sensei returns for another private swimming lesson. Starting with warm-up exercises, she provides meticulous guidance throughout. While focusing on simulated swimming drills, Yaya-sensei's pussy becomes soaking wet. The intense training leaves her students drenched in sweat, bodies pushed to the limit. Once the lesson ends, they move to the bedroom for a cumshot finale—spurt after spurt shooting across her face, concluding the session with a messy facial.
