Undead

Kayo is my BNHA OC. She was working with the League of Villains with an ulterior motive, secretly trying to free someone from them. This fic is an AU where Dabi uses her for sexual favors.
==================
Walking down the dark, worn out hallway, Kayo had tried to avoid the gazes of others. This was her usual mindset ever since joining the League of Villains, as she had a particular history with them in the past. She only had herself to blame for the amount of distrust displayed towards her due to her having joined alongside her brother to keep him safe, then siding with the Heroes to fight for the side of justice, and then again flipping to the Villains after feeling betrayed by her adopted family. Kayo didn't care, however. Rather, she couldn't afford to care for the sake of her mental health.
Growing up without a quirk under the care of Hero Society left her in a position to constantly be looked down on by others. Pity for not having a quirk shaped her personality and childhood, acting as a motivator for her to constantly push past her limits until she eventually became one of the most reliable heroes in training. She developed a familiarity with grappling hooks that aid in mobility, and wouldn't lose to most people in a fist fight, granted the other party doesn't use their quirk. Even if she's up against someone using their quirk, she's proven several times over that she can put up a fight that, at the very least, helps her survive until assistance arrives. Her quirklessness influenced the relationship between herself and her family, which caused her brother to resent her after he was rendered quirkless in an accident that could be blamed on Kayo, depending on the interpreter.
Now that she had become a part of the League of Villains with her quirk revealed, she was still the cause of many looks of disdain. Aside from having recently flipped to her former enemy's army, her quirk itself was something to be feared. Not quite under control, Kayo's ability to heal her own wounds by absorbing the "life force" of others was a danger to any living creature she came into contact with. The only reason she was even alive was because her sleeping quirk activated as she laid dying against a large tree, which later wilted due to tranferring its energy to heal her stabbed chest.
"Undead" was what they called her. The origin came from a time long before now, however. When Kayo was first born into this world, delivered by Chiyo Shuuzenji, her mother died on the operation table. It was discovered that Kayo would have been a stillborn had her quirk not activated in the womb, killing her mother slowly until finally leaving her. Dr. Shuuzenji, now known as Recovery Girl, was mortified to learn that this child had no heartbeat, nor a heart at all. The inside of her chest where her heart would have been was instead strung together by flesh formed as she absorbed her mother's life for 9 months. Despite not being a heart, it acted as a replacement that pumped blood through her veins to keep her alive. When Toga stabbed through what she thought was her heart, she instead cut through the strings of flesh, which were simply reconstructed after Kayo took in energy from the tree she was laid to die on.
After being found barely alive by Toga, Kayo was brought to be nursed back to health by their own doctor. Almost everyone aware of this was apprehensive of the decision, but Toga pushed for her friend to be helped. After explaining the circumstances, Shigaraki eventually gave the okay for Kayo to be reinstated with the League. Convinced by Toga's pleas to fight against the Hero Society that mistreated her, as well as some unfiltered criticism from Dabi, Kayo made the tough decision to once again abandon her life on the side of the Heroes and instead switched her motivation to eliminating the society that made her suffer all her life. For the first time in many, many years, Kayo broke down in front of the two, damning the culture of Heroes that glorified those with "acceptable" quirks and shaming those who didn't fit the critera to be "useful."
By this point in time, Kayo had been stable enough to fight in petty missions, and she was now walking back to the room she claimed as her own. The League, despite being organized enough to commit massive crime raids, lacked the structure of daily life in many ways. One of those ways was typically not finding a proper room for recruits. Due to Kayo's special circumstances, there wasn't anyone who felt comfortable enough sharing a sleeping space with her, so she was able to claim a space for herself. She wasn't the only one who had her own room, as many longtime members did, as well. In fact, there was one room in particular that she had been spending a lot of time in, and others were beginning to notice.
"O-ho~ Is the corpse selling her body again tonight?"
"Your client's room is the other way, sweetheart."
The voices of various lackeys taunted her, which she didn't really mind. Their personal feelings had nothing to do with her, so she didn't care enough to debunk any rumors floating around about her. She did, however, feel a little more agitated this evening than usual, but a brief glare in the voices' direction quickly shut them up.
This evening, she would not be visiting anyone else's room. What was supposed to be a short robbery for supplies for herself ended up as an almost-run-in with a former classmate of hers - Mirio Togata. Kayo had made her peace with betraying her former allies. At least, she thought she did. She always kept herself masked in public so that she didn't reveal her alive status, but this was almost discovered after being chased by Mirio after unsuccessfully retrieving supplies. In just a short one-on-one fist fight, Mirio showed signs that he recognized the moves of his former training partner, but Kayo took the opportunity to flee before any presumptions had been made. Frustrated and filled with mixed feelings, she drearily entered her room, sighing upon seeing a familiar face with a sinister grin.
"Taking such a long time without even visiting me? And here I thought we were finally beginning to open up to each other."
Dabi, also known as Touya Todoroki, stood across from her, leaned against the wall with his arms crossed.
In the time Kayo had first joined with the League, her and Dabi had never really spoken with each other. He never showed interest, and Kayo only cared about Ryou's safety. After rejoining, however, Dabi was appointed by Shigaraki to ensure Kayo showed no signs of betrayal like their former hero-turned-villain, Hawks. Dabi was easily able to see through him, so he was trusted to oversee Kayo, as well.
Personal interest was something he hadn't expected to influence him, but something about witnessing Kayo's breakdown and determination for revenge sparked something in him before he even realized it. He couldn't tell if it was out of sympathy due to similar motivation, but he started feeling pleasure after watching her change from a justice-loving hero to a villain who would stop at nothing to reach her goal. There were some parts of her that remained unchanged, however, which only amused Dabi more.
For example, Kayo had been unsuccessful in fulfilling orders that involved taking someone's life. She found it a struggle to even threaten somebody innocent, in which another villain would have to take her place and finish the job for her. Kayo would always show frustration that she couldn't fulfill the task given to her.
Kayo also had issues fitting in with the League's daily life. Used to following rules and maintaining order, Kayo would voluntarily clean up after others and would straighten out furniture to keep things orderly. This didn't sit well with some, as they felt like she was criticizing them by doing this.
It was apparent to Dabi that little habits and setbacks like these were things Kayo desperately tried to change about herself, but constantly met with failure. It gave Dabi an idea - if she couldn't break free from her old life, perhaps he should break her himself.
××××××××××
It started after one of Kayo's failed assassination attempts. With no one else around, Dabi had to be the one to take the life in that particular mission. Kayo had already been able to kidnap the target and restrain them in a secluded area, but couldn't bring herself to end the victim's life. At first, Dabi began his usual criticism, talking down to her about her failures and lack of conviction. There was something that had to be done so that this girl could stand on her own without him constantly supervising her. Then, an idea had come to his head.
Punishment.
Kayo had faced physical punishment several times in the past, getting beaten by Dabi for wasting everyone's time when she failed. On that day, a new idea had popped into his mind. After disposing the body, Dabi walked himself back to the trembling girl who had already began cursing herself. He crouched down infront of her, and she expected him to start hitting her at any moment. Instead, she felt a hand reach for her chin, lifting her head up into an unexpected kiss.
Completely shocked, her first reaction was to push him away, forgetting about the failure she had just committed. Unfortunately, the trauma of holding someone at gunpoint still shook her, and she was easily overtaken and pushed down onto the hard concrete by Dabi. With no one around as a witness, Dabi once again forced his lips onto hers, this time forcing his tongue through, as well.
Kayo struggled to free herself to gasp for air, but eventually was able to pull her lips away. "What the hell are you doing!?"
Kicking and trying to move her arms, Dabi continued to hold her down tightly and grinned crookedly. Moving his head lower, Kayo felt a pain in her neck, unable to stop a surprised squeak from leaving her mouth.
"My other methods to teach you have been ineffective. I need to change up your punishments so that you'll finally understand how things work around here." Dabi shifted his hold so that both of her arms were now pinned with one of his hand while his free hand began lifting up her top. "These don't look like much, but I'll work with what you've got."
After giving a small chuckle, he soon exposed her bare breasts. Kayo felt his hot breath get warmer as he moved his face closer, eventually feeling his tongue trailing around her nipples. Knowing that they were alone, she gave up on shouting, now trying to focus on using her legs to throw him off of her. This was of no avail, as he continued to overpower her. Without a means of escape, she was forced to go through whatever Dabi had in mind.
"You're not fighting back anymore......not that I mind......makes this a whole lot easier......"
Dabi's tongue continued to play with her nipples, and her suppressed squeaks slowly changed to quiet moans as her face became redder with heat.
Another chuckle escaped his lips, "You sound like you're starting to enjoy it. Even these are getting harder......"
He lightly bit one of her nipples, envoking a louder moan, suggesting to him that she was feeling pleasure from someone forcing themself on her.
"You're rather cheeky, aren't you......Don't worry, I won't be stopping with light play."
Using his free hand, he was now lowering the shorts she had been wearing, which caused her to start struggling again.
"Tch, quiet down!" Dabi shouted and brought his lips back to hers to shut her up.
Twisting his tongue with hers, he continued to pull down her shorts, along with her underwear, until her lower region was fully exposed to him. Not giving her a chance to take a break for air, he took no time entering two fingers into her already-lubricated entrance.
He lifted his head up as she gasped for air, "Looks like it won't be difficult getting it in. Your body's already begging for it."
As he continued to move his fingers inside of her, inserting a third, Kayo understood that it was futile to resist. She couldn't understand it herself, but her body was reacting in ways she didn't want to agree with. Dabi moved his mouth over hers once again, this time gently moving alongside her pace. Kayo was unable to resist the urge to kiss him back, and didn't even notice that he removed the hand that was restraining her arms. Without even realizing it, she had already wrapped her arms around him, pulling him closer. She hadn't noticed him removing his fingers until something hotter pressed against her.
Breaking away from the kiss, she looked up at the man now narrowing his eyes, "...Why are you doing this...?"
In a quiet voice, Dabi responded, "For a while now, I've wanted to break you."
As soon as it was stated, he thrusted his entire self into the virgin all at once. Fully inserted and reaching the base, the two were now entirely connected as Kayo shivered in pain. Without even waiting for her to adjust, Dabi began moving inside of her, thrusting rather quickly and giving no time for Kayo to get used to it. The pain mixed with pleasure caused Kayo to moan involuntarily until it slowly subsided into solely pleasure. Her expression hid no emotion as she panted and held on tight to Dabi.
He brought his face down to hers again and slightly readjusted his position so that he could pound into her even faster. Locking tongues with each other, the two began chasing the ecstasy that awaited them.
Dabi's thrusts quickly became more erratic as his desperation to release inside of her heightened, and Kayo's fingers dug into his back as she craved him with her entire body.
Their kiss became messier with each passing second, until a grunt came out of Dabi's mouth as he gave one more violent thrust into Kayo while she moaned sounds of relief and satisfaction. Pushing himself inside as far as he could, Kayo felt his liquids filling her. She couldn't think of anything in that moment except of the bliss that overtook her. Dabi once again moved his tongue inside of her mouth, relishing the pleasure as much as he could before it faded away.
Finally sliding himself out of her and pushing himself up, Kayo laid on the concrete as Dabi's liquids had begun spilling out of her. Her lower region felt sticky and messy, and a bashful feeling began to arise as she tried closing her legs that Dabi been observing. He quickly held both of her legs open before she could, however, and he grinned towards the girl who looked like she was about to cry in shame.
"Can't you see I'm not safisfied, yet? We'll keep doing this until I say so, and I don't think I'll be getting tired of it any time soon."
As he chuckled again, Kayo shut her eyes upon feeling him enter the hole that had already been violated once more.
In that day, Kayo didn't have the mental strength to count how many times he had released himself inside of her, giving her the same cruel smile each time. What scared her the most was that with each passing second, she felt less shame and more desire to chase ecstasy again and again.
××××××××××
As Kayo understood it, that day was probably when Dabi had successfully taken control over her in both spirit and body. She had a strong enough mind to act naturally among others, and even continued to fail when told to kill. However, whenever she found herself in a closed room with Dabi, she felt unable to resist whatever he demanded. His demands were never anything too complicated, as he only ever wanted one thing.
"Hurry up and undress. You're using your mouth today."
Upon hearing his demands, Kayo removed her clothing and brought herself down to her knees as she leaned on his lower torso.
"Use your teeth to unzip it."
Just as commanded, Kayo brought her teeth to his zipper and pulled it down, his hard cock lifting up and presenting itself infront of her face.
Starting with soft licks and kisses, she soon moved her mouth over his length and bobbed her head gently, invoking a quiet sigh of pleasure from the man. Knowing she was doing well, she slowly moved faster as he began moving his hips on his own.
Unable to wait for her pace, Dabi grabbed her head and took control entirely, causing Kayo to slightly choke. She found no desire to resist, however, and did her best to keep up with his violent thrusting. Pumping himself into her mouth until he gave one final push, Kayo felt a salty taste fill inside of her.
"Savor it."
Upon giving the order, Dabi removed himself from her mouth as Kayo stared up at him with her mouth open and full of his cum. The sight caused him to chuckle as he gave the order for her to swallow. Kayo made sure to take in every drop, as Dabi would always make sure to inspect afterwards.
Despite Dabi finishing inside of her, Kayo knew this wasn't the end of the evening. He brought her down to her bed and fully undressed himself, the two now fully exposed to each other, as they had been several times before already. He pushed himself inside of her lower hole, and the two began another night that would not end until Dabi finally felt satisfied.
