@SolomonG There was one Daz render done by an expert—likely JetSlasher, Flagg3D, or SorenZer0—of a tiny dominatrix holding the leash of a very anxious giantess, kneeling, wearing a ball gag. I can't find it my collection, so I'm searching DA. It was very emotionally and intellectually evocative for me and I've kept coming back to it, wrestling with how this would work. #SizeFantay #SizeErotica

Update: I knew I'd find it as soon as I wrote this.
