Meet the bashful new health teacher, Aoi Mizuno, who finds herself in a compromising situation as she reluctantly agrees to a steamy encounter with her colleague, Hamar. Their bodies entwine on the bed, Aoi's chubby, busty frame pressing against Hamar's as she tentatively explores his desires. She timidly licks his neck, her breath hitching as he pulls her closer, her legs quivering in anticipation.
