Goddess Lena was not ok with this patient. She realized that he was a vile person who liked to hurt and con people. She had a duty to help him get better and she did it. While he was recovering, she wore a strapon and she used it to fuck him in the ass so that he would feel a little of the pain that he inflicted on other people.
Goddess Lena was so sexually starved that after she had treated this patient and he was stable, she sort of tortured him and punished him for having a small dick. She hated small dicks as they gave her bad memories and she did not want any of that. So she ass fucked him besides torturing him in other ways like crushing his balls. But she did not overdo it and when he felt a lot of pain, she made him sleep.
