The voluptuous teacher Haruka has come to our school! Her cups shake and tremble with every step she takes! All the boys in the school are fully erect! The homeroom teacher of three naughty boys, Haruka, is in a frenzy of erotic pranks. She plays pranks on her plump jersey in gym class, gives a soothing blowjob in the nurse's office, and becomes a nude model in art class and health and physical education class. It's full of excitement!
