**Chapter 8: Cruelty Fetish**
**Penny**
Dolly grunted as the dildo pounded in and out of her ass. Behind her, Joanna pumped wildly. Penny enjoyed how lewd and loud Joanna could be, and she allowed the bimbo to moan like a whore while Penny watched.
Nadia had revealed that she had always been nervous to do anal, that she had considered it a boundary she could never cross, and Penny helped her cross it. Dolly needed to be fucked in the ass once a day. Penny said it was to help loosen her up, and she enjoyed Nadia’s nervousness just before she become Dolly for her daily fucking. She enjoyed even more Dolly’s mute acceptance, her placid eagerness to be fucked each day.
It wasn’t the fucking that made Penny wet. It was the betrayal. It was seeing a boundary broken. It was seeing how completely she owned and controlled Nadia. It was how easily she could make Nadia’s body betray her preferences.
Joanna had suggested a strap-on for Dolly, but of course, Penny refused.
