You were secretly changed

The next morning you awoke, to find that Rebecca was already awake. You checked for the remote, and found it still there. However, you were unaware that Rebecca has used it already.

“Morning” you said. Your high pitched, cute, female voice sounded perfectly normal to you, but seemed to amuse Rebecca.

“What is so funny?” you asked.

“Nothing” she said, “just funny that we have a remote to do all this, and we just went to sleep.”

“I was tired” you defended. You ignored her and went to pack the car to go on the journey. It wasnt a long journey for you two, but still.

Shortly after the car was fully loaded and you went to get into it. Taking your time, so you could enjoy Rebeccas new arse squeezing its way into the car.

Rebecca, who was driving, pulled away with surprising speed. This made the remote bounce around, firing off some changes that neither of you would be aware of.
