Zach didn't hugely mind the idea of Romilda touching some of his toys, especially given he had the feeling Crouch had run his hands all over them, which was rather disturbing. Romilda wasn't being creepy to do so. They were just comparing. Picking up a sex toy was not always a sexual act.
Glancing over at the sound, Zach wondered what of his she had noticed. Ah, yes, whips. Zach had a few different kinds of those and a riding crop and a couple paddles of different material. He nodded at her request. That whip he hadn't actually gotten to use with Tracey yet. "It's definitely easy to keep going on those," Zach agreed, "Change just a little bit and it can feel totally different." To handle and to receive.
And somehow that Morag had and used whips didn't surprise him.
