Monsterfuckery!College AU w/ Aged up! Dragon! Kirishima and Aged up! Octopus! Sero with slight hints of Aged up! Naga! Monoma. The drawings I made above are what I think Hanta and Eiji would look like in FULL hybrid mode, however, for the sake of the setting for this story, they’re more humanistic, Sero especially, except for his tongue which is its own tentacle, Kiri’s got his curly tail that wags, gills, and fins on his arms. Naga Monoma is… well… naga Monoma, if you don’t know what a naga is then I highly recommend you look it up. I may end up drawing him as well in the future ;D And to be completely honest, I prefer my Seroctopus idea over Kiri’s.. could you tell?
tw: slight yandere themes! jealous kirishima!jealoussero! mention of naga monoma neito! hints ofkirishimaxsero! fem reader! she/her pronouns! beware of territorial and possessive monsters! smut a little further down, there will be a warning with details!
Setting -> Modern! Humans are rare! Hybrids are more common, human mates are especially rare because most times humans will try and mate with other humans to continue to grow the human population.
Personally, you don’t give a shit about any of that. Anybody could be a jerk, full human, or hybrid. All you cared about was the personality they had.
The same goes for a certain, unlikely couple who had recently become interested in you.
All of you attend the same University and you also work at the cafe nearby the school to afford your rent and whatnot.
What’ll happen when you go on a date with a certain blonde-haired naga and your two crushes coincidentally end up at the restaurant you’re both in?
“Kirishima,” you called out, pushing a large black coffee over the counter to a certain redhead who’d been waiting for the heated beverage. A polite smile adorned your face as your hands briefly touched, Kirishima’s cheeks becoming slightly red as he took the cup and quickly blurted out his gratitude, “T-thanks, L/N.” A small laugh escaped you when you noticed the slight blush on his cheeks, nodding your head in acknowledgment of his thanks.
The dragon hybrid stepped back and went over to the table he was sharing with Sero Hanta who had already gotten his own drink and was sipping the cold green tea lemonade mix. Kirishima’s curled scaley tail swished around behind him as he hurriedly went to sit down, getting comfortable for a moment while sipping his coffee. It was ridiculously hot and most would probably cry, but he was a dragon and temperatures like this were nothing to him.
“S’cute how you get all tongue-tied whenever you talk to her,” Sero teased, absentmindedly nibbling on the metal straw that was in his cup, “She seems to think the same.”
Remembering just a few seconds ago, a groan left the dragon as he worriedly scratched his scalp in frustration, “Don’t even remind me. It’s so hard trying to keep my cool when all I can smell is her.”
Sero pulled the straw from his mouth and gave his signature smile, straight white teeth revealing themselves between slightly plump, curled lips, “Imagine what she smells like when she’s in heat.~ Never been with a human before but I’m sure it’s absolutely heavenly.”
“Hanta! That’s not— it’s not manly to think about those things about sweet lil’ Y/N. She’s too inno-“
“Cut the shit, Eiji. You know damn well you think about this every time you lock eyes with her. Don’t think I can’t smell your arousal from a mile away,” Sero teased, rolling his eyes playfully as he took another sip of his drink.
“H-hey! No! I- whatever, fuck off,” he growled, starting to chug his coffee as a means to bring down the boiling dirty thoughts he was starting to think up in regards to you.
Y’see, Sero, and Kirishima’s relationship wasn’t exactly an odd one. They considered themselves as partners, they did everything couples would do and so— maybe they were? Or maybe they were just really close bros. They were both madly in love with each other, both of them were satisfied with each other and such but then they both laid eyes on you and something was suddenly missing.
“The one new guilty pleasure I developed over the pandemic was playing Mario Kart on Nintendo Switch. It became therapeutic, and I have a pretty obsessive personality, so once I get into something, I really go in. I actually formed a group of friends, our own Mario Kart Crew haha, it sounds kind of dorky but I’m so glad I found that and them during such a chaotic time.”
