The package was pretty unremarkable. It was small, about the size of a softball, wrapped in plain brown paper. I tore into it without bothering to look at the return address, assuming it was the jewelry I bought online. It was not.
Instead of finding a bit of glittery metal, I found a dark sphere, about the size of a baseball. It was hard, but gave under pressure, like rubber, but slicker. It felt slightly warm, and I couldn't tell if the warmth was simple being absorbed from my hand, or was generated by the ball itself. It was kind of pretty, the surface swirling with dark blue and purple streaks. It was almost hypnotic, the way the colors twisted and blended into each other.
"Weird," I muttered to myself, examining the discarded wrapping. There was no return address, no address at all for that matter. Someone must have put it in my mailbox. I suppose this should have alarmed me, but it seemed harmless enough. I shrugged and put it on my nightstand, smiling at the colorful swirls.
I spent some time online, trying to identify the mystery orb, but had no such luck. I came across a few conspiracy websites claiming it was some kind of egg connected to an alien invasion, but that seemed just south of bat crap crazy, so I ignored it. As the evening wore on I gave in to fatigue, deciding that this mystery could wait for another day. I rubbed the "egg" affectionately, then slipped out of my bra and jeans and fell into bed.
I woke up to something brushing against my leg. It wasn't an unpleasant sensation, far from it. It was like a gentle pressure against my skin, like a lover kissing her way up my thigh. I didn't recall picking up any girls at the bar or anything, nor had I managed anything more than a polite wave with the cute girl down the hall from me, so I assumed this was a dream.
Only it wasn't a dream. I was very much awake and my mystery lover was getting very close to my panties. I tossed the sheets away, but I still couldn't see who, or what was in my bed. What I did see was my pretty purple orb, or rather what was left of it. Shards of it were on my nightstand and floor, glittering in the moonlight.
I finally caught a glimpse of the leg kissing bandit as I sat up, spotting a shiny black streak against my inner thigh. I had no idea what it was. It looked kind of like a slug, but it wasn't slimy. It was less about six inches long, thick and fat, with a sucker-like appendage at its head. It continued moving up my thigh, seeming very interested in the space between my legs.
This was about the point where a normal girl would leap out of bed screaming, but I was more curious than anything else. The sensation was quite pleasurable, and it didn't seem to be hurting me, so I figured, what's the harm?
I gasped as the creature finally reached my panties. It brushed against my labia through the thin cloth, kissing my pussy lips, pleasing me in a way I had never experienced. "Well hello to you too!" I groaned contently.
The longer it worked against my panties, the more my arousal built. It didn't take long until I was no longer content to keep the cloth barrier between us. I shifted the crotch of my underwear to the side, allowing the creature unrestricted access to my pussy.
My reward was instantaneous. It latched onto my clit and sucked away at it. "Holy fuck!" I squealed as my little lover brought me over the edge. It let go right as the intensity was too much to bear, opting instead to probe its head inside my cunt.
The rational side of my brain, the side that wasn't addled by post-orgasmic endorphins told me there was no way in hell I should let an alien slug inside my pussy. I ignored it. I could feel its muscles contract as it worked its way inside me, pulling the length of its body between my lips. "Fuck me!" I screamed as the last of it disappeared inside my cunt, coming hard as it moved in deeper and deeper.
I could still feel it moving as I lay in a sweaty panting heap on top of my sheets. I pushed two fingers inside of my sex to try and find it, but I only felt my own warmth and wetness. I still felt movement and I swore I saw a slight bulge in my abdomen. I considered the possibility that the creature managed to pass through my cervix and into my womb. The thought amused rather than frightened me, the prospect that I might be pregnant with an alien slug monster eliciting a giggle.
"Well, that was fun," I murmured sleepily my new passenger, half-convinced that I was dreaming. "Good night."

I slept hard, waking late in the day. Fortunately, I worked from home, so I didn't have to be anywhere. As sex dreams go, the previous night's was the most intense I'd ever had. I woke up to sheets full of sweat and girl cum, more that even the most ambitious evenings of lesbian sex had ever produced.
I blinked when I saw the egg shells. I knew for certain they were egg shells now, spotting the film of the interior lining on the remaining fragments. That also explained the flutter in my stomach, which I woke up thinking was gas, because it had to be gas, because there was no way in hell last night was real.
"Oh my god," I murmured, placing a hand against my slightly swollen stomach. Something moved against it.
I considered going to a hospital. A perfectly rational course of action, given the circumstances. However, I knew that if I went to a hospital, three things would happen. They'd think I was crazy, but they'd examine me. Once they examined me, they'd find out I was telling the truth. Once they found out I was telling the truth, they'd remove the creature.
I didn't want that to happen.
Call me crazy, which was fair, seeing as I had an alien parasite inside my uterus and my plan was to leave it there, but I had no intention of letting any harm come to it. "I must be losing my mind," I muttered, brushing my stomach with my fingertips. The creature tapped against them in response.
I decided to ignore the big problem and focus on a smaller, more manageable one. I was starving. I headed for the kitchen and tore into my fridge, noshing on a couple of random things before discovering that I had a hardcore craving for dairy. I sat at the counter noshing on a block of cheese, washing it down with the remaining half gallon of milk in the fridge.
My dairy binge took the edge off, but I wasn't quite satisfied. Fortunately, there was an Italian place a few block away that delivered and they had pretty amazing alfredo. I ordered enough for myself and four other people, then watched TV while I waited. I only just remembered to throw on a pair of yoga pants before answering the door.
"That'll be forty dollars and seven cents," the deliveryman said. I watched him glance into my empty apartment. I felt the judgement, but I did not care. I did care that the cute girl from across the hall spotted me in my disheveled glory, but she flashed a grin and waved, despite me looking less than gorgeous.
"Here you go, thanks," I said, handing him a fifty. I waved back at my neighbor while accepting the food, temporarily forgetting my bizarre situation, but new movement inside my womb brought me back to reality. I closed the door on the both of them and set to work feeding my little parasite.
Over the next several days I went through gallons of milk and pounds of cheese. I still craved other things, but I literally couldn't get enough milk. It all went straight to my belly, which took on a distinct paunch that continued to swell over time. By the end of the week I looked like I was in my second trimester.
Despite the fact that I actually looked like I was pregnant with an alien slug monster, I was still oddly content with my situation. It helped that I looked completely normal otherwise. Despite eating my weight in a week, I was still as trim and attractive as ever. The only change besides the baby bump was in my breasts, which seemed to get the pregnancy memo and started growing along with my belly.
I actually liked my new body better than the old. I felt like a fertility goddess, my swollen belly and gently padded curves radiating femininity. Neighbor girl seemed to notice too, and while I hoped she didn't end up assuming that I was straight, I was happy to catch her eying my body.
I was a little nervous about the prospect of actually giving birth to whatever was inside me. I didn't know when or if it would stop growing, and I was vaguely concerned that my poor stomach might just burst. Mostly it was the uncertainty that weighed on my mind. I knew that something was going to happen, but I wasn't sure what.
