Lorna wants to serve PD because she has this silly idea that if she does well he might love her back. She is just desperate for attention. PD cares more about the tools he uses against her than he does this pile of young, writhing flesh in front of him. Her body and mind are just things for him to bend and break for his own amusement. She serves him hoping in vain for some sort of reward.

Lorna is going to have to learn: when Master A says he wants to see her cum it means he wants to see her cum until she starts to cry. She knows that she is his dirty little slut and she would not have it any other way. He is free to punish her or pleasure her as much as he likes. The only choice that she needs to make is whether she wants to beg for mercy or scream for more.
