Day 1: Possession-Ception

Abigail let out a heavy sigh as she slumped onto the sink. Not even bothering to even consider fixing or touching up her makeup, she stood there, contemplating her life. Knowing that, in only a few minutes, she'd have to deal with boarding a flight and all the fun that came with that, she silently appreciated the coolness of the probably-gross sink.

Feeling her phone vibrate in her back pocket, Abigail considered pulling it out. No doubt it was a text from her wife, reminding Abigail to pump before the flight home. Maybe a picture, too, probably alongside a joke about how their child wasn't screaming and crying, unlike the seemingly-mandated one on every single flight. Maybe... a "saucy" picture, teasing Abigail about what was waiting at home, legs spread and that glint in her eyes...

Abigail bit down on her lip as she began to rub her thighs together, the denim of her jeans creating a bit of a ruckus. Shutting her eyes, her mind began to wander, constructing a scene. Her wife, meeting her at the door, teasing Abigail about being jet-lagged before slyly mentioning how their child was out cold and wouldn't wake up for anything. The deep kiss that followed, each hand frantic in its attempts to strip off any and all articles of clothing as they stumbled into the bedroom. The silent pause as they each contemplated bringing up the lack of shaving during Abigail's trip before...

Abigail's fantasy was shredded as she felt a cold, metallic sensation at the base of her spine. Her eyes shot open, only to immediately struggle to keep them open as her eyelids insisted on drooping back down. Forcing herself to stay awake, she managed to look over her shoulder and catch a glimpse of a massive grin peeking out from behind a face mask, a pair of piercing blue eyes lecherously sizing her up, and what looked like a pile of skin laying on the floor of a stall, its door flying open and slamming shut again and again. Before she could even begin to process what was happening to her, her mind went dark, her body deflating into a pile of warm, steamy skin in the grasp of the grinning, blue-eyed man.

Wasting no time, as if he was putting on a full-body suit, the man jammed both legs into the "wound" on Abigail's body before yanking it up. He didn't bother holding back his moans as the pleasurable sensation of hijacking someone else's nerve endings traveled up his legs, Abigail's body adhering perfectly to his form, her shape overriding his. His arms were next, "his" new fingers wiggling excitedly as he felt his new outfit cling to him, shrinking him a fair few inches in the process. Then, after a few squeezes on "his" new chest, he pulled Abigail's face over his own, his moan shifting from his deep bass to Abigail's higher tenor as her face wriggled and stretched over his own.

"Abigail" blinked with her new, bright blue eyes, her tongue running over her lips. Giving her ass a firm slap and letting it jiggle for a bit, she chuckled. Making a mental note about how horny and wet "older" women were, "Abigail" adjusted her outfit, giving extra time to make sure that her bra and her knickers weren't too snug. Keeping a hand on her chest, "Abigail" sauntered over to one of the bathroom stalls, crouched down next to the deflated pile of skin on the floor, and picked it up. For a brief moment, "Abigail" contemplated stuffing the "spare outfit" into some luggage but, ultimately, opted to press her lips against the "wound" on the skin's back and blow. As it inflated, its mind still unconscious, "Abigail" stood back up and stepped out of the stall, more than eager to enjoy "exploring" her fine-ass body during the upcoming flight...

Except, "Abigail" only managed to get a quick glance at her body in the bathroom mirror before she was leaning on the sink once more. Her new, bright blue eyes slam themselves shut as a bolt of lightning shot up her spine. Her cheeks became bright, rosy red as she struggled to contain her moans as she felt it roll around inside her, causing pangs of pleasure with each and every movement. Jamming a finger down the front of her jeans, "Abigail" silently cursed that her host had, apparently, some sort of vibrator jammed deep inside but only managed to get her middle finger inside her hot, damp folds before everything suddenly went black for "Abigail".

"Abigail" blinked a few times, the bright blue color of her irises steadily becoming replaced by an unnaturally bright pink with each blink. She slowly stood up straight, each movement awkward and unpracticed. Clenching and relaxing her hands, over and over, a smile slowly crawled across her face. Smacking her lips together, "Abigail" silently mouthed word after word, as if she was getting the hang of speaking for the very first time. She was so engrossed in this task, however, that she failed to notice the stall door creaking open and a very confused set of gray eyes locking onto her body.

"Abigail" managed to hear a voice shout, "Sorry about this!" before the loud slaps of bare feet echoed throughout the bathroom. Looking up in the mirror, she caught a glimpse of a woman, a naked woman, sprinting directly at her before "Abigail" felt an impact, as if someone had shoved her but became attached in the process. More than a little confused, "Abigail" tried to look over her shoulder before a loud gurgling sound echoing from the pit of her stomach snatched her attention there instead. Wondering if there was another like her, "Abigail" felt her body start to shake, her clothes suddenly feeling a bit tighter, a moment before everything went dark...

"Abigail" let out a groan as she glanced around with her gray eyes. Grumbling under her breath about where she was, why she was naked, and how she was forced to use her powers, she adjusted her clothes. Continuing to grumble, this time about how a change of clothes was needed the second it was available, "Abigail" stepped out of the bathroom, hoping that her host's flight was headed somewhere nice and crowded, with plenty of options to pick from. Except, "Abigail" had only managed to get as far as the plane bathroom before her plans were derailed before they ever really began.

A hand covered her lips, a sinister smirk shushing her as she tried to explain her situation, that it was either Abigail's body or streaking through the airport she had no recollection of arriving at. The sinister smirk chuckled, saying that the flight was short a single flight attendant that day, but it was alright, because Abigail's body would like great in the uniform. Then, the hand covering her lips turned into a green, slime-like substance before rocketing past her lips. Her eyes rolled back into her head, her mouth, throat, and stomach bulging out as the green substance streamed inside, seemingly without end... until Abigail's body jittered a bit, a sinister smirk crawled across her face, and her eyes became a bright green, just as the last of the slime slipped down her throat, the "bulging" turning into a bit of extra mass around each and every one of her already-delectable curves. causing the clip of Abigail's bra to sheer off and the button of her jeans to shoot off and ping throughout the airplane bathroom...

"...Damn, I was gonna take that one..." Rachel grumbled, floating out of the plane bathroom with a frown on her transparent face. "Like one of those fucking Russian doll things, I swear..." She continued to grumble, shooting a glare at the gaggle of flight attendants milling about on the plane, their eyes all unnatural shades of green...

First-off, I wanna say that today's prompt was weird for me. Not because of the subject matter, but because Eagle_Bacon did a poll of themes/topics for this year and I wrote this one in. No idea if they picked mine specifically or multiple people wrote something like this as well, but when they revealed the list I felt weird seeing it there, in a good way. The alien that possessed Abigail first is obviously inspired/shamelessly stolen by "Popuni" (which I put as a tag for the chapter as well) from the series "Popuni Kei Joshi Panic!" by Himekuri and Kurisu, which is pretty great, highly recommend (although the ending is kinda mid imo). Writing this also reminded me of an old caption by Kanske, called "I´m going for the hat trick and beyond!" which... is now 10 years old, holy shit.

Anyway, my favorite piece today is from Fanterfane (being this hard to pick on day one does NOT bode well), I really like the facial expressions:

Originally, I was gonna do honorable mentions each day too, but there would be like 50 of them because I'm indecisive as shit, so... I'm not gonna do that.
