Goddess Lena wanted to make this guy humiliate himself. So she teased him. And she used her nylon lingerie which she was sure would make him horny and also get him do what she wanted. When he was ready for her, she got him to jerk off and to humiliate himself. She made it look like they were having a great time together and the guy did it the way she wanted.
From their interactions with him, these mistresses could tell that this guy was clueless. The mistresses were bored with him and they wanted some fun so they took advantage of the clueless bastard. He was in pain and he was humiliated but the mistresses did not care as all they wanted was fun. And being sadistic mistresses, his pain was their pleasure and it was a joy for them to inflict pain on him.

This mistress wanted her feet to sweat. That is why she wore nylon stockings. She knew that if she wore them with her boots, she would sweat after some time and it happened.

She even choked him as she trampled him in the neck.
