Prologue, Vague, Detailed (Skip here for smut)
Prologue:
Lily stepped out of the chem lab and took a few deep breaths before heading to her car.
It was dark now. The days had been getting shorter, and the time change only excaberated that. Nervously, she walked to her car while fidgeting with her hands; holding her bag’s straps, putting them at her sides, then caressing her thighs and bottom before repeating the cycle.
Her mind wandered off to the recent reports of late night gropers and sexual assaults blasted to the students’ phones, and her own thoughts of how they would feel up her legs and ass while she was pinned to a wall, her mouth covered to prevent any unwanted attention. Realizing where she was stroking herself, Lily instead crossed her arms sheepishly and whistled to herself instead, as she rounded the corner, and walked down some steps leading into the mostly empty parking lot.
*Almost there,* she thought to herself with mock cheer. She was whistling some rendition of Don’t Stop Believing as she skipped every other step before jumping the last 4, still tense, but now merrily swinging her arms.
Her car was parked in the furthest lot, bordering some woods. Lily had about 300 feet to clear to get to her car, and she was thankful there was a line of street lamps leading to her car. As she got closer, she relaxed.
*I guess I was just being paranoid.*
Her hand went to one pocket, then the other, groping for a set of keys that weren’t there. Flustered, she then took off her satchel and placed it on the ground, bending over to search her bag with one hand while the other held her phone up for light. Unfortunately, her car was just outside the ring of light from the last lamp, and Lily cautiously eyed the woods as her heart steadily reverberated louder in her head.
Finally, she found her keys and she rose before inserting them into her door and turning her wrist. By now, her heart was pounding out of her chest, and she locked the car doors before taking a minute to calm herself down and take another few deep breaths.
*In,* through pursed lips, and *out* with a bwooh. *In, out.*

Vague:
The night air was cool, and the city was dimmer than usual due to the power saving measures. Several power plants had been affected, with official statements blaming natural disasters.
As she calmed down, she noticed an oddly saccharine scent. She turned on a light and doubled over to examine the floor, then the floor to her side, then twisted back to examine behind her. As she twisted back, she thought she felt a damp sensation on inside of her leg, but chalked it up to perspiration from stress. *Gross.*
Still perturbed by the increasingly strong, fruity odor, she put her keys into the ignition and began to drive home. She felt really tired now, and very warm. Reaching to turn down the heat, she instead rolled a window once she saw that it wasn’t on.
Lily’s anxiety was replaced with a hazy calm, and she began to feel lightheaded as the cool autumn breeze caressed her face. Despite the somewhat chilly air, Lily felt herself burning up as beads of sweat soaked her clothes. At the next light, she peeled off her sweater to reveal her tank top, now clinging to her chest.
Somehow, exposing her skin made her feel even hotter, her body now throbbing unnaturally. Her cheeks were flushed and her body glistened in sweat, as she hurried home. Rationalizing her symptoms as some sort of flu, she beared with her heat for the rest of the ride, as stripping any more would be indecent.
She barely made it into her garage, and closed it as her legs began to tremble. Looking down, she saw that her jeans got soaked somehow without her perception, and curiously, when she felt her damp pants her legs didn’t seem to feel her light probing.
As she massaged her legs, feeling slowly came back to her before snowballing into an intense pleasure. The haze that had lingered in her head went away as Lily’s body convulsed in pleasure.
The throbbing heat was now unbearable, and each pulse was headed by an explosion of pleasure from her crotch. Slowly, a cool moist feeling layered itself on the unbearable heat, slowly slithering up her torso to her chest, before they two exploded with the same pleasure at her groin.
She couldn’t muster the strength to more closely examine what was happening, as her eyes rolled back with pleasure, and her mind being whited out with pleasure, the only experience right now being pleasure. Eventually she passed out while her body continued to buckle and smolder in her car.

Detailed (The Smut):
When Lily got in her car, a small alien glob from below her seat flattened itself and slithered up a leg of her skinny jeans, while injecting a sensation dulling serum through many microscopic needles to prevent her from taking action too soon.
It eventually made it’s way to her panties, where it spread itself thinly across the fabric, and began to exude various serums to be asorbed through the skin; the same dulling serum, a stimulant to increase blood flow, and a precursory viral soup to prep her body for modification.
The slime pressed her panties closely to her skin, and slurped to create a seal, creating a cameltoe beneath the stiff denim, exposing Lily’s plump mound. As the stimulant circulated through her body, it’s temperature rose and she began to sweat profusely, as well as involuntarily ooze out arousal fluid from the gentle suction of the slime. Once her head was addled and her lower body was numb, the slime dissolved her panties.
Now directly in contact with her groin, the slime gently began to probe and contract, undulating in such a way that her vulva was being rubbed slowly up and down, a gentle pressure parting her labia. Several nubby tendrils formed and entered her anus about an inch before spreading her open, allowing many fine long cilia enter her digestive tract, to better administer chemical cocktails directly into Lily’s blood stream.
They latched to the walls of her rectal cavity, and pumped in more aphrodisiac, which for now only gave her a warm sensation while she was still under the effects of the numbing serum. Once the numbing wears off, her nerves will be unbelievably sensitive, leaving her incapacitated just from the slime’s gently probing.
Sensing she was now home, the slime neutralized the numbing serum wifh another injection,and slid into the depths of her vaginal canal before capping her cervix. There, it slathered a strong antispasmodic onto the cervix, relaxing it. The slime continued to massage and gently prod her cervix open as the tendrils in her anus receded.
Two thicker tentacles were formed and they peeked out of Lily’s vagina to gently slide under her top to reach her pert breasts, where they cupped her nipples and began to suck as a ring of small needles injected her with body altering compounds.
As the numbing wore off, Lily began to convulse as her nerve endings were overwhelmed by the small goo’s machinations, eventually passing out as her body continued to change.
Her nipples were now a deep purple color in contrast to their previous pale pink, swollen and lengthened to about an inch long, and leaking milk. As the tentacles continued to suckle, they began to tug and twist as well, pulling her now heavy teats from her body and stretching Lily’s nipples further.
Lily’s cervix was now pliable and loose, and the slime forced its way into her womb. There, it sealed it off before filling it with more viral solution and microscopic gene modifying cells, which made their way up into her ovaries and coated her eggs and uterus, allowing her to be impregnated by any species’ semen.
The tentacles on her nipples were now satisfied by the growth of her breasts, now veiny hand-filling sacs of fat. Her nipples began to be penetrated as milk spurted out, a cavity forming within her chest to hold future seed and spawn.
The tentacles continued to push in and out of her breasts, slathering their insides with milk and fluid as each thrust deepened her new orifices, before swelling up, spreading her nipples wide as seed and eggs filled her breasts. Once they were taut, the tentacles plugged her nipples with a thick plug of translucent mucus, sealing in a mixture of milk and spawn.
Satisfied with its work, the slime recollected itself and slid out of Lily’s womb after sealing her loose cervix with a similar plug. It then turned into a thin soupy form as it made its way up to her face, where it poured into Lily’s nose and made it’s way up to her brain.
