Yes, you, unknowningly

You smiled to yourself as you spotted these changes, pleased that the remote was still working perfectly and changing people without them knowing.

You might not have smiled as much had you known you were also swapped, unknowingly, with the remote.

You were completely unaware, but your arse was not actually your own arse. The huge arse you were sitting on, the one which was so soft and round and perfect and lovely to squeeze originally belonged to Debby. Debby was 25, 5 foot 1, and had a huge arse and hips. She also wore glasses, had long straight blonde hair, and had a pair of huge 34H cup breasts which she sometimes tried to hide, and sometimes tried to show off. She was confusing like that.

Her arse was now flat, very boyish, yet somehow still feminine because of her hips. She was still attractive, and her boyfriend was still happy to be with her.
