Jessica looked puzzled at your hand for a second as the number of potatoes in your hand seemed to have not changed... and then sensed a change in the weight on her chest and looked down "...WHAT HAPPENED TO MY BOOBS?!?" You hadn't really done much to her aside from swapping her melons sizes with actual melons, but you weren't expecting her to realize everything you had swapped.
"Umm... Well..." You said feeling a lot guiltier you went to the small melons you placed on the table and picked them up "These look somewhat familiar?"
"What the hell happened to the big..." Then she looked back to her boobs... Then back to the melons... she remembered how big her boobs were and how big the melons were. "You turned my boobs into melons?!?"
"I was going to turn them back..."
"You will, but not before we play around a bit!" Jessica's pulse was racing as she got really excited as she played with her boobs a little. A little irritated you looked at the tiny melons as they swelled to their normal sizes... Or maybe swapped normal sizes as Jessica's tits shrank in her hands as she had been enjoying being the bustiest girl she knew to be back to what they used to have been. "Hey!" Jessica yelled.
"Calm down, let's have dinner first. Then we can mess around with the numbers that compromise reality."
You had cooked a stew with Jessica, the food was nice, but she seemed a bit pouty... It was hard to blame her. You show her something fantastical and then yank it away and tell her to finish her dinner before having dessert. As the dishes were being washed you placed the first of the cleaned dishes and imagined the dishes and silverware and whatnot into two groups. The number of washed and unwashed... Jessica was pouty as the number shifted as she found that there was suddenly a lot fewer dishes to wash. She looked over to you as you said "Well... I don't like doing the dishes either." You let Jessica do the last dish as you reached into your pocket as you found a number of different coins. As she finished up you asked "So what do we wanna mess with first?"
