Inflating Origins - Under One Roof

I watched through the window of the car as the driver, mysteriously sent, approached the farmland. The trunk started rumbling loudly. I looked frantically back, shoving my teal hair off to the side.
“Jesus, what’s back there?!” I grimaced. The driver shrugged, unfazed by it.
“Something I was hired to carry. Don’t quite know, myself,” he said. Great, so much information. As he stopped the car, the trunk popped open. He opened my door, and then took a large tank out of the trunk. It was clear, and filled with what looked like Jell-o. I squinted at it, suspicious. The driver set the tank in front of the door and knocked. The farmhouse door opened, answered by a woman with red and green hair. A dark-skinned woman stood behind her, watching me with soft eyes. The woman in yellow smiled at the driver and handed him a small bundle of money.
“Zank you!” she said, her accent thick. “You ‘ave done such an excellent job!” He tipped his hat and drove off. The tank of green sludge wobbled, almost tipping over.
“Alright, first things first,” I groaned. “What is that, who are you, and why am I here?” The woman giggled loudly, snorting.
“Zat is a special surprise! My name is Miro Fraisier, and you are ‘ere because as soon as I saw you at ze store, I knew I ‘ad to ‘ave you!”
“…Soooo, you’re a creep?” I folded my arms, huffing. The darker woman shook her head quickly.
“No, no, Miro is amazing!” she said in almost a lulled tone. Something weird was going on, and I didn’t know if I wanted to stay and find out. As she lead me inside, she pointed out where all the rooms are, and led me to a specific room.
“Zis one is yours, Miss Saa!” she patted the bed. It did look comfy enough, I suppose.
“Wait, how do you know my name?” I narrowed my eyes.
“My research is very thorough,” she said, almost seriously. I shivered, this was getting much too serial killer-y for me. The tank shook again, this time the glass shattering. Miro giggled excitedly and ran to the spilling ooze. I peered out of the doorway and saw the lime tidal wave rush towards my end of the hall. I screamed, trying to shut the door on it. There was a loud thud and a very bubbly “Ow!”
Curiously, I opened the door again, slowly. The puddle of green formed into a humanoid shape. Long hair flowed from her head, a bow on top. I looked her up and down and backed up.
“What the hell are you?!” I yelled, appalled at the creature.
“Oh, uh, yeah! My name is Mally Abel! I’m a slime!” she said, giving an oddly large smile. “Miro found me in an abandoned building and she rescued me, yeah!”
“Why are you in my room?” I seethed, accepting that this was probably my fate anyways.
“Oh, cuz this is my room too!” she smiled wider, her face stretching a little. I groaned and rolled my eyes. Great.
Suddenly, without warning, the slime leapt at me, the taste of fresh honey crisp apples rolling down my throat. I tried to scream, but it only came out as a warm gurgle, bubbles rising along the slime’s body. Her giggle echoed from inside my belly, which started expanding further. I backed up, collapsing against my bed. Like a water balloon, my belly sloshed and filled up rapidly. I tried fighting her off but she was way too devious and, well, malleable.
Like a hyena’s call, her laugh echoed again. She was only half way gone and my belly was already looking full-term pregnant. My shirt rode up, sliding up my round, shining belly.  The more the slime pushed her way into my body, the heavier and rounder my belly got. I felt the insides of my stomach roll around and coil, the slimegirl inside laughing and wriggling. I tried screaming again, the gurgling rippling through the slime’s body again. I could hear Miro’s giggling from the hallway, and the darker woman came to the doorway and gasped. The apple slime forced herself deeper down my throat and belly.
“M-Miro was this a good idea?” the other woman asked.
“’Ush, Lura, they’ll be like two grapes in a pod!”
“EAS!” I gurgled, trying to correct Miro on her improper cliché. The slime coiled deeper into my belly, pushing out heavily. I groaned as she finished, rubbing my belly. Miro giggled and entered the room, looking at Lura, then back at me.
“Well, Lura, do you zink she’ll be a good addition to our ‘appy family?” the strawberry-haired woman asked. Lura looked at me apologetically, blushing deeply.
“U-uh, yes, Miro,” she said softly, a trace of smile poking at the ends of her lips.  I tried to stand, but the slimegirl inside me weighed down like a pair of watermelons. I moaned and groaned, feeling like a woman pregnant with sextuplets. Miro poked her finger into my immense girth and I shivered with the weird touch.
Not that I really liked it or anything.
I think.
