Day 2 of Kinktober 2021 - Edge play.
I will leave a small explanation here... for those who don't know, edge play is not the same as edging. In this case, it is the use of a sharp or pointed object, something that has an edge, including knives, sticks, enough ice or fire to open the skin...
TW: I never mention that I draw blood but that should be understood by the kink, so be warned.
A possible bad kink negotiation awaits you and perhaps a somewhat toxic moment... oops!
And well, that's it... We are getting closer to being up to date, although it seems to me that it won't be so easy... to tell you the truth :(
The sound of the door echoed throughout the apartment as Shouto entered, alarming Katsuki in the process and causing him to immediately meet him near the entrance but stopping suddenly a few feet from him. Shouto was covered in sweat, dirt and dust, making Katsuki extremely alert upon seeing him; he had no idea how he had gotten to that state but it worried him a lot... not that he would say it out loud, of course.
Katsuki closed the distance that separated him from his boyfriend and practically pulled him by the arm to go to the bathroom, dragging him while he asked about what had happened; Shouto didn't answer him and Katsuki wanted to turn around to threaten him with a couple of explosions but he held back until he turned on the bathroom light and was able to really detail the expression on Shouto's face and the small cuts that covered all his exposed skin.
"Katsu, my quirk," Shouto whispered, stumbling as he tried to get away from his boyfriend.
"Sho, what the hell happened?" He asked, holding it up so it wouldn't fall off.
"They injected me with something," Katsuki could see the fear in his eyes, "and I can't control myquirk… please, stay away."
"Are you an idiot or what the fuck is wrong with you?" Katsuki didn't want to take it out on him but his nerves were acting alone. "Tell me what happened."
"Leave me alone, Katsu, please." His voice came out much lower than normal, his words separated by vapors of different temperatures coming out of his mouth.
"Nope, I'm not fucking crazy," he replied, starting to take off Shouto's hero suit so he could step into the shower. "Come on, collaborate a little."
"Katsuki, no." Shouto was waving his arms in an attempt to get his boyfriend's hands off him. "I'm going to hurt you..."
"I don't care, you idiot," he exclaimed, pinning one of his wrists against the wall. "You need help... and urgently."
"No, Katsuki. You can't be close when…" You could tell how annoyed Shouto was by the small frown on his expression, "Katsu, go."
"Let's go to the shower." Katsuki had already undressed him and was now pushing him into the shower. "You perfectly know that I can hold my ground against your quirk."
"It's not the same, Katsuki." Shouto gasped with the effort of holding off until his boyfriend walked away. "Now I'm drugged."
"And I don't give a shit that you are," Katsuki turned the knob towards the icy water and kept Shouto under the stream, "don't keep trying to push me away, you idiot."
"I don't want to hurt you, Katsuki," he whispered back, shivering from the change in temperature.
"You're on fire, Shouto." His tone sounded softer than before. "Please explain to me what they did to you."
It turns out that Shouto had found the lair of a clan that had escaped from the police a couple of months ago and passed the invisible protective barrier ALONE, and he had also not told anyone that he was going to see if the information someone gave him was real or not. In the end he met two of the leaders of the group and, since they had surely recognized him, they attacked him… one of guys had the quirk of immobilizing his opponent with his eyes and the other could grow needles from his skin like it was nothing.
In less than what Shouto would have liked to admit, they both had him static and with a fine needle pricking his left arm. A liquid of doubtful origin entered his body immediately and Shouto began to feel his temperature rise and rise, and he couldn't balance it as he was used to; what had been injected into him caused his quirk to spiral out of control.
"You must be a moron," Katsuki said while putting conditioner on his hair, "you know you're safe now... remember that the house is fire and explosion proof."
"But you aren't!" Shouto yelled, a hint of pain in his tone. "Katsuki, I don't want to feel even worse now."
Katsuki finished bathing him in a couple of minutes. Shouto didn't give up, he kept asking Katsuki to leave him alone and him, who was much more stubborn than Shouto, ignored it until he closed the stream of the shower and felt his boyfriend's temperature rise again; steam was beginning to come out of his entire left side but not a single grain of ice covered his body… and that worried Katsuki more than what he was able to show.
He grabbed the largest towel they had to dry his boyfriend but when he turned to look at him, he realized that Shouto was practically dry by now and raised an eyebrow, not because his boyfriend had dried himself but because not even a minute had passed that they had finished and that was not normal at all.
He grabbed Shouto's wrist when he tried to walk past him to get out of the bathroom and received a fierce look from his two-toned eyes, causing him to open his own red ones in surprise at that new expression on his boyfriend's face. Pulling is wrist towards him and holding his chin with his free hand, Katsuki bit his lip doubtfully.
As almost always, he threw his sanity out the window and pushed his boyfriend until his back was pressed against the wall behind them. Katsuki stood on his tiptoes and kissed Shouto intensely, parting his hot lips with his thumb and holding the wrist that was still between his fingers against the ceramic; Katsuki thought it would be a good idea to make his boyfriend think of something else to help him calm down... but he was very wrong in the way.
Small flames began to erupt from Shouto's left hand, burning Katsuki's skin instantly. Shouto tried to push him away upon hearing the groan of pain that came out of his boyfriend but stopped when he saw the expression on his face; it seemed like, although it had taken him by surprise, the pain of the fire had pleased Katsuki. Shouto took a deep breath before clearing his throat and approaching his boyfriend's neck.
"Katsuki, are you sure about this?" He asked, lowering his voice and intertwining his two hands with his boyfriend's. "You know what can happen."
"And you know we've talked about it before, njhm," Katsuki gasped as he felt the edge of the counter against the small of his back, "besides, you know I like to see you like this."
"You remember what to do if it starts being too much, right?" Shouto asked, his lips brushing his ear.
"What do you take me for, you idiot?" Katsuki replied, tilting his face to give his boyfriend more space. "Don't you dare to stop until I say so."
"I think your roles are reversed, Katsu," he murmured against his neck, licking from his collarbone to his jaw as he finished the sentence.
"Stop teasing, half and half." Katsuki climbed on the table as he said it.
"Impatient, as always." Shouto put one arm around his waist and lifted his head with the other.
Shouto left a trail of kisses all over his neck and shoulders. He drove both of his hands to his chest and cupped his pecs, pressing his thumbs against the nipples, drawing a growl from Katsuki, transforming it into a moan as the temperature of his fingers rose; Katsuki wasn't sure if it had been on purpose or not, but he had liked it and wanted Shouto to continue treating him like that.
Katsuki lowered his face, to try and kiss his boyfriend, to drown out the sounds that escaped from his throat. Shouto played along for a few seconds but he already had other plans in mind, an idea that seemed very risky but that he would carry out now that his boyfriend had given him free rein to do whatever he wanted... Shouto couldn't ignore the pain in his crotch and the growing pressure in his abdomen.
It wasn't long before Shouto raised one of his hands to his boyfriend's blond hair and pulled it back, burning the ends of several strands in the process, and told him, in a voice more passionate than before, to go into the room and lie down on the bed; Katsuki obeyed as soon as he had some room to get out of the bathroom, almost running nude in front of his boyfriend.
Shouto followed him until he had him spread out under him. Their gaze scanned the muscles and scars that covered the other's body, Shouto took the opportunity to slowly rub his erections; twin moans flooded the room at the desired contact. Katsuki raised his hands to rest on his boyfriend's hips but Shouto hit them, repeating the friction with a little more pressure and biting his lip while looking in his direction.
"Katsuki, I'm going to use the fire," Shouto muttered, bringing his fingers to his boyfriend's abdomen.
"I don't know what you were waiting for, dum... Ahhh!" The yell Katsuki let out, along with the way he arched his back, made his crotches rub again and they both sobbed.
"You look so attractive like this, Katsuki," Shouto whispered, tracing lines with his index finger on his skin, a small flame burning at the tip.
"Shouto," Katsuki closed his eyes and sighed before continuing, "only you make me feel like that."
Shouto felt his words heading for his cock right away and a current rushing up his spine as Katsuki pushed his hips underneath him. He decided he wouldn't give his boyfriend room to move, so he got up slightly and turned him, pressing him against the bed with his own body.
"You're misbehaving, Katsu," Shouto whispered, placing two fingers on the bone between his shoulders, raising the temperature quickly. "Don't move."
The phrase stopped Katsuki in an instant, causing him to grip the pillows tightly and hide his face. Shouto began to go down his back, fine red stripes covered his skin, not much highlighted by the brown tone of it, but contrasting with the pale color of Shouto's; he couldn't stifle the sob that rose in his throat.
"I'm going to write words on your back and I want you to repeat what you understand."
"Yes, Shouto!" He yelled in response, eager to repeat the sensations and thus reach the climax he had been waiting for.
Shouto ran his fingertips over his skin, writing letter after letter until he finished writing his lover's name, drawing sobs, fat tears and groans from Katsuki. Shouto didn't want to stop listening to his boyfriend getting wrecked under his touch but he needed some stimulation to keep himself from going crazy.
He turned Katsuki around again and, knowing how much he liked to suck his dick, placed his knees on either side of his head and raised his hips a bit, so that Katsuki would have it easier; from that position he could see how his boyfriend's cock vibrated every time his quirk made contact with his skin and that fascinated him.
He didn't even wait for Katsuki to settle before running one of his hands down the inside of his thighs and squeezing his hips in an attempt to get some support, little flames coming out from both sides thanks to the drug that was still circulating in his body. Katsuki rewarded him with a loud suction, causing his eyes to roll back. Shouto had to bite his lip harder than he had expected.
"Are you okay, Katsuki?" He asked, taking a deep breath to turn down the flames in his fingertips.
"Njhm!"
Shouto wasn't sure if that was an affirmation or what, so he did his best to create a layer of ice on his right hand, although he had to make it thicker than normal so it wouldn't melt right away and he had to continually renew it so that it does not disappear; he brought his fingers up to his boyfriend's cock and curled them around the base.
"SHOUTO!" He screamed, when he felt the extreme change in temperature, unable to avoid the convulsion or the way he pushed a couple of times against Shouto's icy hand; spilling into it.
"Katsuki," he didn't want to continue in that condition. Shouto was about to pass the point but he didn't have enough strenght to do so, "please."
And his boyfriend, as if he had read his mind, obeyed. He ran his nails down his back as he licked and sucked his cock hard, bright lines beginning to cover his body. He scraped his thighs with his teeth, crawling up onto his cock, before biting right into the crease of his crotch and pressing a finger to the tip of his dick, scooping up the fluid that had built up.
Katsuki only gave him a chance to put his boyfriend's member in his mouth before he came, his cum going down his throat helplessly and his hips thrusting a couple of times before Shouto was able to stop all his movements; he inhale deeply, melting over his boyfriend from the intensity of his orgasm.
They hadn't felt like this for a couple of weeks, without being able to enjoy something so pleasant together... hero work always interrupted any scene they had planned when they knew that they both would be home. Neither of them moved for a few seconds, trying to calm down their breaths and their heartbeats.
"I didn't hurt you, did I?" Shouto asked, still resting his face on one of his boyfriend's thighs.
"Not at all, silly," Katsuki murmured, his voice still hoarse from screaming.
"I want to kiss you but I don't want to move," Shouto said, sighing.
Katsuki grabbed him by the hips and turned him until their lips met. A short kiss and the soft caress of a wet tongue attacked Shouto on request; he couldn't help but smile sweetly at the romantic attention and reciprocate his slow movements.
Shouto adored those moments in which Katsuki let his barriers fall down and hugged him, squeezing him in his arms, caressing his skin with extreme affection and losing himself in the tenderness of his actions; although Katsuki would never say it, he knew he felt the same because he always looked for those moments when they finished... and they always fell asleep like that, collapsed in each other's arms.
I hope you liked it, even if it's just a little tiny bit...
Tomorrow I should be posting two stories: pet play and role play.
