Your dream that night had been pleasant, the bed nice, and you were able to wake up without an alarm today. In the foggy haze you noticed some lumps on your chest and muttered "...some effect from the micro-..." your voice was softer, a bit higher pitched "-Wave" you said your attention more focused to your voice. You gave a squeeze to your chest which not only was inflated but felt sensitive and not warm... well they were warm, and not microwave warm... Your hand was more slender as you saw it better and... A little exploration found a crevice and your butt was significantly larger.
Issue 1: Morning bathroom time. Was a relatively minor issue all things considered and a way to get more aware of how your plumbing worked in one of the more important ways considering you were babysitting and not Fucking someone. It came relatively easily and you caught yourself wiping your crotch... It felt right even though you hadn't ever been aware of a woman's bathroom habit.
Issue 2: mismatched clothing. This change was just your body it seemed as your cargo shorts and boxers felt... weird on your widened hips, and your V-neck t-shirt felt less appropriate with how they were framing your breasts... and the feeling of your breasts rubbing against the fabric wasn't the most pleasant.
Issue 3: figuring out what happened... You just fell asleep, wasn't like you had activated anything and the bed didn't seem overtly feminine or something. Did you accidentally break a rule and this happened as a result?
Issue 4: Andrea seemed to have stolen your dick... The Munchkin was still wearing their nightgown but it was obvious that Andrea was more of a little boy
"Did you do this?" You asked Andrea
"...maybe..." Andrea said in that annoying kid way and you gave the boy a glare "You seemed interested yesterday in your chest so..."
"You know how to undo this right?"
"...yeah..."
"You do realize I can't go out in public dressed like a guy in this body right?"
"Can I have more nuggies for breakfast?"
"I'm not inflating my breasts for you no, you can have some cereal." Andrea nodded and the two of us went to the kitchen where I poured some sugary cereal, took out the milk carton, poured some out for Andrea before it ran out half-way. I shrugged "Guess I'm eating my dry. but that's..." Then I felt a pressure in my breasts
"...House rule, you have to replace the milk if you use the last of it." Andrea muttered as my breasts started growing and filling. My nipples felt more rigid as some dark patches were starting to appear on my shirt. So I ran to the bathroom with the milk jug starting with the right breast milking myself was an experience... especially since my breasts were pretty uneven at the end of milking my right breast as my left was swollen with milk... but some more milking made them a bit more even. Then my turgid brown nipples seemed to lighten to a pink color as whatever lactation rule had ended. Feeling a bit tired I brought out the milk and Andrea looked like she was expecting some of the milk... I then took a glance at a jug of my bodily fluids and decided... it was going right back into the fridge before I took my bowl of cereal in front of the couch and collapsed a bit as I just felt tired.
