Swimming coach makes Rina and a guy do nasty things in a locker room

As any other Japanese girl, Rina obeys those in authority. So, she takes a vibrator and toys her pussy through a swimsuit as her swimming coach request. Then Rina's teammate toys her pussy with a dildo making this chick squealing and shaking. She feels very embarrassed and horny at the same time. Soon the coach orders Rina to give a blowjob to her friend. She kneels down and sucks a dick obediently while the coach moves her head back and forth.
