You notice immediately

You keep laying against Mommy, not understanding why he was messing with that remote talking about some how making your breasts bigger. (flash) You feel your bra tighten. You sit up, what the Fuck? You grasps at your bra now spilling with titties where just a moment ago was empty cups.

"How the hell? Mommy what did you do?" You stare at Mommy in disbelief

"Interesting" Mommy said looking at the remote "That change you noticed, well that's weird, it must be because I was touching you that time?"

What did he mean "That Change" "That time"?

"How can you do magic? Mommy what is with that remote? Have you changed other things"

He looks at the remote and then you and ponders.
