An arse swap

Rebecca aimed the remote at the final few people left in the room and fired. The first beam flew off and hit Cassandra in her head. She was just getting up from the table to return to her room.

She is 23 years old, five and a half feet tall and has long straight black hair. She is slightly chubby and has a nice pair of 36D cup breasts. Her one issue is that she has been brought up around no one else the same age as her, so her mental age is still a good 5 or 6 years younger than it should be. And most people usually assume she has a learning difficulty.

The second beam was directed at Nina, who was just leaving the room.

“Random?” Rebecca asked. You nodded silently and watched.

You could just about see Nina as she walked off, her arse getting ever so slightly larger. Not in a sexy sense, however. Fat was bubbling in and her arse went from being tiny and flat to being slightly chubby, as if all the fat she put on went to her arse.

Cassandra’s arse got smaller and flatter, but it was barely noticeable in her slightly baggy outfit.

“Not too bad.” you said, “At least we could tell this swap occurred.”

“What do you mean?”

“Mental swaps are hard to spot a lot of the time remember.”

“True. Shall we try a mental one though?”

“Sure. On them then” you said, pointing.
