Moxxie loves having things shoved into her holes, especially if it saves her from suffering. Pain can be its own reward but for her it is just a path to what she really wants. Moxxie is a slut, through and through, and if it means having an orgasm or tasting a dick again she will endure anything.
It does not take PD long to twist that to his own end. Everyone knows a pussy is extremely sensitive after a couple orgasms. Once she has cum she can barely keep her wits about her. He puts the hood on her and gives her some more. Every time she cums it is more intense than the last. When he takes the hood off she may think it is over, but he is waiting for the machines to wear out and she has got a long way to go. PD will check back in a few hours.
