One evening not far from Patterson University it was a clear cool night. There was a few inches of snow on the ground. It was quiet and peaceful as the land near the school was mostly forest.
The silence was broken as something bright began to fall from the sky smashing in to the ground with a loud bang that was heard for miles however nobody payed much attention to it. A fire crater was left in the middle of a small field with a few small patches of fire around it which melted some of the snow.
A shattered rock laid in pieces in the crater. Everything seemed still until something began to leak out of them. This creature had been frozen in the vacuum of space for many hundreds of years but the fire from the collision finally warmed it enough for it to start flowing together in to a mass of what looked like black blob of tar that began to crawl out of the crater. It touched some snow and pulled away in pain. It new it had to find a warm host soon.
---------------------
Less then a mile away Anna was in her dorm room with her boyfriend Chris. Anna was an attractive brunette and her and Chris had been together for a few months. They were waiting to have sex until they were both ready which was starting to get hard on Chris but he knew she was worth the wait.
They were in her bed making out. Chris ran his hand up under her shirt to which she grabbed him by the wrist pulling it back out."Now Chris we talked about this, if you want it that badly you have to be willing to wait for it."
"Yeah i remember, its just........ you are so f'n beautiful Anna, hard to keep my hands off you!"
She smiled and gave him another kiss before saying "that's sweet, but don't worry, it'll be worth the wait!"
"Ok, well time for bed i guess, see you tomorrow?"
"Of course! Night babe!" She said as he got up and headed for the door.
Anna took off her jeans and her bra getting ready for bed. She played with her phone for a little while before she turned off the light and went to sleep.
Outside her window which was open a little to let a cool breeze in to help her sleep was a small black blob wiggling around in the snow looking for warmth. It started to crawl up the wall and force its way through the screen and plop on the bedroom floor. It then crawled around until it heard Anna make a slight cough in her bed and it froze and flattened against the floor to hide. It soon realized it needed to find a place to camouflage itself somewhere where it could stay hidden while at the same time preparing a suitable host for itself. It could feel Anna's warmth and decided to crawl up the bed and investigate.
As it slithered it way up it moved under the covers getting closer to her leg feeling her body heat. To further up it went the warmer it got so it moved closer to the source until it found a thin piece of cloth around her crotch. It didn't take long for it to reach out and begin to bond with her underwear taking over the whole piece and mimicking the fabric in order to stay warm and begin its work on her.
Anna stayed asleep and was completely unaware of the alien creature that had bonded with her panties and was even starting to make changes to her as well.
-----------------------
Hours later Anna awoke to the sound of her alarm clock going off. She stretched and rolled out of bed ready to shower and get ready for the day. Before she jumped in she pulled out a new pair of panties and a bra throwing them on the bed before removing the pair she was wearing and throwing them in the hamper.
After Anna left the room the creature knew it needed more time to prepare her and abandoned the underwear she had thrown and headed for the bra and panties she had thrown on the bed. It climbed out and shot out tentacles of slime grabbing them both and bonding with both mimicking the fabric again. It then waited for Anna to return.
As Anna got out of the shower she wrapped a towel around herself before walking back in to the room. She dried herself off and threw the towel done before grabbing her underwear and slipping both pieces on still unaware of what had happened to them or what was happening to her.
Anna went through her day like normal going to every class and meeting Chris for lunch. Only thing that seemed odd to her was she would start to get horny randomly throughout the day, especially when she was with Chris. As they ate lunch together she couldn't help but think about jumping his bones right then and there.
At one point she had even slid her hand under the table while they were eating and began teasing his crotch with her fingers. He did not mind as it was the most attention he had gotten from her but he wasn't sure what had suddenly come over her. He looked around the cafeteria to make sure nobody was noticing what was going on to which nobody seemed to. He felt his zipper suddenly slide down as her hand was sliding in to his pants.
"Woah there Babe? What's gotten in to you?" He asked.
