I'd love to be completely owned by a dominant black man. I'm not really into pain, beyond an occasional spanking, but i love transformation fantasies and I'd love to be owned by a man who would share or sell me, who kept me at his service full-time 24/7, and who changed me in some way that showed me to be indisputably a slut-***** (tats, for instance)
As for the plumping up thing, I love the idea - though I'm already much bigger than I'd like to be - and have come across some sites on it, including a forum that has "changing stories" many of which are about "******" weight gain.
I also love the good-girl-to-slut change talked about above, though again that won't ever be me because I'm nothing like a good girl, lol
