Different artists have different preferences for the proportions of the female bodies that they draw. I have to say, your art is very near to my ideal. I almost always say "wow" when I see your latest art.
You wake up slowly. You feel groggy and dazed. "Oohf" Your muscles burn as you sit up - sore all over. You look down and gasp. A soft curvaceous body is laid out underneath your gaze. Moving as you move. Breasts rising and falling with each panicked breath. It wasn't a dream, the transformation was real. That's your body.
Metal cuffs jingle from your wrists and you can feel something similar around your neck. Solid metal rings with no visible clasp - magically attached. There's no escaping it - you're a slave. And there's only one reason to give a slave a body like this...
Awesome art, great curves, love the collar and cuffs. Your description is really good too. Would be awesome to see some art detailing the descent into submission.... perhaps curiousity first, then entrapment, then training, then slavery/bondage
