The clothing

Bellatrix's gaze lingered on the shop assistant for a moment, her eyes flashing with annoyance at the interruption. "No, he will need more clothes," she said finally, her voice dripping with disdain. "I want him to look like the perfect little servant. Get me some more dresses, and some stockings. And make sure they're all pink."

The shop assistant nodded hastily, scurrying off to obey Bellatrix's commands. Harry, still reeling from the aftermath of his orgasm, felt a wave of shame wash over him as he realized he was going to be dressed up like a doll again.
