White mesh thong and a green toy

You’re looking at someone from behind, their ass cheeks are rounded and shiny, like they’ve been oiled up. They’re wearing a white mesh thong with lace trim, and you can see a small black tattoo on the crack. A bright green, textured toy is inside their butt, pushing out slightly. The skin is glistening, maybe from lube or sweat. The person’s lying down, maybe on a bed or couch, with a black fabric underneath. There’s a tattoo peeking out on their left hip. The lighting is kinda purple and blue, like a party or bedroom vibe. The whole thing feels intimate and casual, like someone just got down to business without any fuss.
