I have recently discovered that bodyswap videos of the adult entertainment variety have been made and do exist!
I have provided links to some at the right.
There are more, I downloaded many, but now they are harder to find.
For instance, Xev Bellringer has a lot of missing free links now but these 3 are the best thankfully. You can buy the videos off her site too. Same with Sexy Saffron, she has a whole transformation fetish section and I could only find a link to part 2 of her 2 part mom swap series. Also Tara Tainton is the really curvy one in the tan dress and she has others only available for purchase on her site but somebody uploaded her mom possession one!
I would suggest saving them before they get taken down. Enjoy!
