You feel thicker

Your eyes flutter open, and you take in your surroundings. Sheema is strangely missing, and as you stand up to go look for her, you feel a strange weight to your body that you've never experienced. Your entire body has seemingly thickened while you were knocked out. Your breasts are even bigger than Sheema's, your shoulders are wider, your ass and thighs have plumped up, and even your stomach has gotten some softness to it. You walk into the kitchen, and have to adjust your gait so your thighs dont chafe. At that moment, you begin to feel lightheaded, and you hear a voice inside your head, "what the hell?" It says.

"Who was that!?" You whirl around, looking for the source of the noise.

"Why can't I move? Why are my tits so big? What happened!?"

"Sheema?" You say out loud.

"Mia?" The voice says.

"Are you... part of me, now?"

"I think so... i can sorta move stuff around in here. I'm in some sort of room, and there's buttons and levers and cables and shit everywhere. Everything is labeled in these weird symbols that glow when my hand goes near them. What happens if I flip this one?" She apparently flips a switch. With no apparent effect.

"Nothing, so far--ahhh!" Your left nipple lights up with sexual pleasure, as if someone had set a vibrator next to it, and turned it to the maximum setting. You whip your hand up, and clasp it over your left breast. "Scratch that! My left nip just fucking lit up vibrating!"

"Oh, shit, sorry! Here, putting it back, now!" The vibrating stops, "if i flip this one right next to it, does it do the same thing to the right?" The bibrating starts, again, this time on the right.

"Ahh, fuck! Yes! Shit, turn it off!"

"Oh, fuck, sorry!" And the vibration goes awag, once more, "theres a button right between them, is it the 'milk' button?"

"Hey, wait, no-" suddenly, your breasts double in size in the space of a tenth of a second, before going off like pressure washers, blasting milk all over your kitchen. The feeling is like none other, and your knees give out, allowing you to topple to the ground. Your breasts have almost normalized in size, and the excess milk continues to shoot out in bursts of a few ounces. "So that's what that one does..." you pant, "maybe avoid it in the future unless youve got some way to modulate how much they make."

"Yep, got it, leaving that one alone. Can we stand up?"

"I can't seem to, no. Maybe there's some command you can give from in there?"
