The problem with that steady stimulation is Lapis doesn't want it? She prefers the jerking motion, honestly. The jerking hips really did it?

So if Peridot isn't doing it, clearly Lapis has to, and she jerks her hips back against Peridot, and then forward against her paw. Please. She's so desperate? She's about to take hold of herself too, just for the more consistent stimulation to somewhere she'd never really thought to be sensitive, but it is.
