Beaten by gym instructor's feet

Charlie has hired a private trainer to get him into shape, but he's not taking it seriously enough. He's wearing wrong clothes, he's cheating his workout and he comes as he want to the lessons. Rose, his instructor, is pretty unhappy with him. Rose gets really mad at him and starts a fight with him. Charlie being a small weak guy and Rose being a tall amazon-like girl she kick his ass pretty quick and makes him smell her sweaty feet after being in the gym all day long. Charlie is powerless and Rose has absolute power over him. As punishment Charlie is made to smell her feet and gym sneakers and worship her like a goddess. He is complete loser under Rose's feet.
