This is a fairly ambiguous shot. You could read all sorts of dynamics into it. But for me, it comes across as puppy play (in the most abstract sense). He’s poised, eager, focused, ready to go. She’s having fun teasing him and setting him simply tasks. It’s not necessarily an animal roleplay, but that kind of underlying vibe comes through the image. They’re both in a crouched posture, but where hers is playful and relaxed, his is attentive and just slightly nervous.
I believe this comes from the Club Stiletto site.
