You dropped the remote

This startled you for a second, and you knocked the remote off, firing off an unplanned random change.

One beam hit you, and the other beam hit Zoe. You didnt clearly notice the change, but subconsciously you did. Yuo were now called Zoe, and she was now called David.

You also ended up dropping the remote, but thankfully Debbie didnt even notice this, so you quickly scooped it up and hid it for a while longer.

That drop, however, had fired off an unknown change. The first beam hitting Jemma and the second beam hitting Josh. If you were touching the remote you would have noticed Jemmas breasts deflate to being completely flat, and Josh’s chest suddenly grow quite a nice pair of boobs, bouncing away under his clothing now, rather than Jemmas borrowed clothing.

Eventually you got to the top of the hill, the center point of your walk. You had not done any more changes as you didnt want to risk Debbie seeing, and you dropping the remote again. You had spent the majority of the walk up talking to each other about some of the girls on the walk with you, and sometimes pausing to let people pass you to watch some arses as well as breasts.
