A bright light streaked across the desert night sky. Like most shooting stars, it was a meteor. However, unlike most shooting stars, it was not just some rock that fell to Earth. It fell to the ground and landed with a crashing boom that echoed for a mile. If anyone were around, they would have heard it. Unfortunately, there was no one around. No one, that is, except for her.
Sara cursed loudly as she heard the sound. A minute before, she'd been cursing less loudly at her misfortune. Getting lost in the desert at night was not something that most people would regard as being a good idea, and even as experienced as she was at hiking, she couldn't help but feel like an idiot now. "What the fuck was I thinking?" she thought to herself. Wandering off the trail for a minute had been such a good idea when she knew where the trail was after all. The sound of the explosion didn't do much to allay her fears, but now curiosity pulled at her yet again.
Emerging from some dry brush at the edge of a crater, Sara took in the sight. It was a decent sized crater, several dozen meters wide and several deep. In the cool desert night, she could feel the heat emanating from scorch marks in the blasted dirt.
"What the hell is that?" She asked aloud.
In the center of the crater lay a metal sphere the size of a basketball. It was shiny and chrome and was still glowing from the heat of the crash, though it was clearly cooling quickly. Obviously, it wasn't any ordinary meteorite, but what the hell was it then? Some kind of satellite? Sara needed to know more.
Pulling her long blonde hair into a ponytail, Sara worked her way down into the crater, struggling to keep her boots firmly planted in the steep, loose dirt. She thanked God that her admittedly short legs were firm and toned from plenty of exercise. Finally, she reached the bottom, sliding the last few feet to the sphere.
Sara leaned over the object, looking it over for any marks, but she couldn't find any. No "US AIR FORCE" or "NASA" or anything. Nothing gave away where this thing came from or even what it was. However, there was one square-shaped outline at the top of the thing. Sara stretched out her hand, holding it just above the area to check if it had cooled yet. Satisfied that it was, she gently touched the surface.
"PSSSSSSHHHH!"
A blast of warm air hit Sara in her face as pressure escaped the outline. She stumbled back, her foot hooking on a rock and tripping her over as her back hit the crater wall. The air smelled strange, but immediately she felt strange. She was obviously startled but weirdly something stirred inside her that she shouldn't have been feeling at the time.
She felt horny. Really horny.
And as the seconds drew on she felt even hornier. She should've been concerned about the new opening that had replaced the outline on the meteorite, like an opened hatch on a spaceship. She should've been concerned that she could hear something...slimy... inside the now open sphere. But she found herself thinking less and less about how strange it was.
She was beginning to feel excited.
Sara's right hand found a familiar space between her legs and immediately began groping. Her breath became quicker as her grip tightened and she quickly slipped off her backpack and used her left hand to slide down her shorts.
"Oh God... oh... oh fuck... what's happening... to me?" She muttered as she slipped her hand under her panties as she began to stroke her quickly moistening pussy. Some small part of her mind was still there, questioning why she suddenly was trying to masturbate in a crater in the desert. But a larger part of her mind was already gone, replaced by a burning desire to feel something, anything inside her. Her fingers dove into her slit over and over as she became wetter and wetter, her panties and shorts barely halfway down her pants as she sat in the dirt. But in the sphere, something was stirring that had been waiting for this perfect moment.
Slowly it emerged, poking a light purple tendril out of the sphere and into the air. It probed around for a few seconds, swinging quickly around and taking in its surroundings. Sara saw it, but rather than being scared she instead felt a surge in pleasure as the very air seemed to warm around her. She stroked her burning pussy faster as more of the creature slid out and into the night air. It looked like a slug, only about six inches long and an inch wide. As it slid out, a slimy trail followed in its wake. Sara regarded the creature for the briefest of moments. It was small... It was slimy... It was...
"Fucking hot!" Was what she found escaping from her lips in a moan. She should've pulled up her already soaked panties and shorts and taken off as fast as she could. She should've ran away and never looked back. She should have. But she didn't. The slug knew. As it slithered towards her, passing her boots and climbing onto her legs, it mused to itself with its surprising intelligence. It knew she was gone as soon as the superpheromones hit her.
As it continued up her legs past her knees, Sara could do nothing but moan now, louder and louder the further it traveled. It moved up and over her shorts, still only just past her thighs. It moved past her panties just beyond that. She stroked her pussy faster and prepared herself for what she somehow knew was coming, withdrawing her hand from canal. Her juices were dripping down her taint. Her breath was quick and hard. "Please" was all she could mutter with anticipation and eroticism in her voice.
She was ready.
The slug slowed just before it reached her pussy, poising and recoiling just before her opening. Slowly it moved around her labial folds as Sara moaned in continually increasing ecstasy. The slug moved on top of her toned stomach, with one end at her pussy and the other at her belly button. Its head raised itself before her waiting pussy and paused for a moment.
Then it dove in.
"OHHHH FUCK YESSSS!!" Sara screamed with unbelievable pleasure as the mysterious slug she'd just found slithered its way into her tight vagina. She'd had guys inside her before, but this was... perfect. It was everything she wanted. It was pure sexual bliss. The slug slid deeper and deeper, its slime mixing with her pussy juices to form a perfect lubricant. The slug was sliding in but still found difficulty reaching its destination, as this particular human was tighter than it had expected. It didn't matter. She was totally receptive, and progress was quick. Sara moaned louder and louder as she watched the slug disappear inside her. "Ugh... ugh... ugh..." was all she could mutter, totally lost in bizarre lust. Five inches of it were outside her, then four, then three, then two, then one... then it was gone. Her now slimy pussy lips closed behind it as it disappeared inside her.
She could still feel it inside her as it moved further up her body, but sensory overload was beginning to overtake her. It just felt... too good. Sara drifted off with a smile on her face as she lost consciousness.
A few minutes passed as Sara laid in the dirt. The slimy trail up her legs and into her cunt began to cool and dry. The crater became quiet.
Then she stirred, her firm arms moving slightly as she opened her eyes.
"Mmmmmm..." Sara said, licking her luscious lips and stretching out her arms. A smile crept up her face as her hands moved down her form, going through her hair and down past her shoulders, pausing for a moment at her C cup breasts. She gripped them as though for the first time, as if she hadn't held them before. Because she hadn't.
Sara wasn't Sara anymore. The slug had done what it was bred to do. It had bonded with her body and taken control of it. Even if Sara, the human Sara, had still been awake, it wouldn't have mattered. She would have done her new master's bidding anyway.
But the new Sara sat up, then stood up, pulling up her panties to her pussy. She stopped for a moment, burying two fingers in there, then pulling them out coated in the mixture of her own juices and the slug's slime. She licked them sensually. "Damn... 'I' taste sooo good" She said, giggling like the girl she now was. She repeated the process for a few moments, then finally finished redressing, pulling her backpack over her shoulders and setting off up the crater. A mischievous grin crept across Sara's face.
