Goddess Lena was looking for ways to continue having fun at the expense of this guy and she settled on using nipple torture to do it. She was not concerned about what this guy felt. All she knew was that she needed to have fun and she had to ensure that it was worth it. So she stripped him naked and she tied him up before whipping his nuts and torturing his nipples.
Goddess Lena was angered by the fact that this guy had great sex at her expense but she got nothing in return. She did not cum and she was pissed. So she opted to torture his nipples and to whip his dick. She did the same to his balls and he felt pain which was out of this world. He regretted why he had not paid attention to her fun as much as to his own fun.
This guy thought he was something he was not and goddess Lena was tired of always trying to correct him and putting up with his nonsense. So she changed tact and she punished him so as to put him in his place and avoid constant conflict with him. The mistress tied him up so that he would not resist and she tortured him by crushing and squeezing his nipples as tight as she could then she whipped them.
