The above art is the first sketch of a male player character stand-in collared and leashed. This image when complete will be added in as a counterpoint to the similar female image in the Pet-Play Trainer content. The artist NimbleTail has graciously cleared me posting all the versions here as always.
If you want to see more of their work, you can find it through the following NSFW DeviantArt link here, or at their Patreon page here.
