Black Swan (not at all connected to the movie)

This is my best description of subspace that I think I can write and is one of the reasons I haven’t updated this in a while. I’ve been researching subspace and one of the hard parts of that is that it’s different for men and women, but I could really only find descriptions about women’s. I’m not a sub or masochist and therefore have never felt subspace. However, a friend of mine who is in the BDSM scene said that a state I described to him that I enter sometimes when writing or thinking about what to write sounded like subspace to him.
If you think they are acting odd after sex in this scene, crashing is normal after achieving subspace and Kakashi is giving him aftercare for it. I hope this is somewhat accurate.

Kakashi might have forgiven him, might have decided no argument was worth losing his precious little swan, but he decided this was the perfect excuse to abuse him a little. To whip the cum right out of him.

Sasuke knew what Kakashi was planning and was frankly fine with it. He came into Kakashi’s bedroom like a lamb giving itself up to slaughter. He wore the collar and Kakashi’s favorite outfit, relieved that the bastard hadn’t bought him a dress yet. It would be just like him to buy him a maid’s uniform. He promised himself that he would throttle Kakashi if he bought him any kind of dress.

He still couldn’t walk around unashamed wearing women’s underwear, so he kept his robe draped over his shoulders. Of course, Kakashi wasn’t going to let him get away with that for long. Almost as soon as he walked in, Kakashi was on him and taking off the robe and throwing it to the side. He proceeded to grope Sasuke’s thin body.

“I like the fact you’re shy about it,” Kakashi whispered against the shorter man’s temple. “I like you humiliated.” He stroked the Uchiha crest on the collar.

Sasuke blushed. He did feel a dress coming. But for now, Kakashi knelt down in front of his lover and nipped at his fabric covered nipples. His hands moved over Sasuke’s sides and back.

Kakashi went lower to Sasuke’s trapped cock and licked at the silken fabric, making it wet while rubbing his cock nicely. The head of Sasuke’s cock peaked out the waistband and Kakashi tongued it as well. Sasuke’s head went back and enjoyed the sensations. Kakashi’s hands traveled up and down Sasuke’s muscular legs, exploring the hairless, smooth skin, tracing muscles.

“Fuck, you’re sexy,” Kakashi breathed as he brought his hands back up his legs.

Kakashi stood and pulled out something new: six inch wide, black fabric ribbon. He stood behind Sasuke and pulled his arms back and wrapped Sasuke’s forearms together behind his back so that he could almost cup his elbows with his hands. Sasuke was limber, but it wasn’t the most comfortable position, yet it was tolerable.

Kakashi eased Sasuke to his knees and pulled his head to his bare cock. He kept his hand on the back of Sasuke’s head so Sasuke couldn’t pull away. Well, he could if he really wanted to, but he wasn’t about to ruin their play unless he was in danger.

Sasuke found this really arousing. He really couldn’t get his arms free; the wrap was tight around his wrists so it would take hours of shimmying to pull out an arm. Being well bound and his head held still made Sasuke feel absolutely helpless. He was fully at Kakashi’s mercy. He looked up adoringly at Kakashi. He was truly a submissive and was in his place. He drooled, making Kakashi’s cock and his chin glisten. Kakashi forced his cock in deeper and pulled further out to fully enjoy the slutty look on Sasuke’s face and the pleasure of his mouth over his entire length. Then he held his cock as deep in his throat as he could and didn’t move. Then he went back to fucking his mouth. Kakashi could see how happy Sasuke was, the bliss and lust in his eyes. He looked incredibly high.

A shudder went through Sasuke’s body. He was in a slightly dissociative state, but it felt wonderful, like an orgasm brought on purely through emotion. It was an emotional orgasm. His cock was still hard and ready to cum, but the endorphins were already flooding his system.

After nearly five minutes of oral, Kakashi used Sasuke’s hair to pull him back and then took hold of Sasuke’s throat firmly, but gently in his hand and stared hard down into Sasuke’s eyes. Sasuke didn’t look away, didn’t smile, didn’t giggle, didn’t move, he just looked back, trusting and giving himself to his lover. He was also fascinated by the details of Kakashi’s mixed matched eyes. He could stare forever.

Kakashi didn’t soften his expression or praise him; he straightened up and rubbed his wet cock on Sasuke’s face, painting his cheeks with precum with the tip and using the sides and underside to coat his skin with saliva. Sasuke didn’t move, but he did open his mouth a little.

“You can use your mouth,” Kakashi said as he continued to move his cock over Sasuke’s face.

Sasuke moved his lips over the offered flesh and stuck out his tongue. He kissed and teased his master’s cock. Kakashi pulled away to slap Sasuke’s cheeks with his cock several times.

Kakashi knew Sasuke well enough to know what was arousing such a strong, independent, powerful warrior and knew it was the control he’d given away. Voluntarily facing the worst fear of being overpowered and threatened.

He slipped a kunai from the side of the bed where they were always close at hand and knelt in front of Sasuke. He held up the kunai so Sasuke, even a little out of it, could see it. Kakashi caressed Sasuke’s throat with the blade, shaving the very short hair trying to grow there, and moved the point down his collarbone and then down his chest, all the while, looking into his eyes.

Kakashi lowered his eyes to carefully touch the cold steel to Sasuke’s hot cock. Sasuke couldn’t keep from flinching, but Kakashi made sure not to let the edge cut him.

“A pain slut like you probably wants me to cut him,” Kakashi whispered. “I’ll give you a small scar, just to mark you as mine.”

Sasuke didn’t object or say anything; he let Kakashi slide the point harmlessly over his hip and then put a small slice in his inner thigh. Kakashi was gratified to see even that hadn’t softened Sasuke’s erection. He trailed a finger up the cut and scooped up the blood and then licked it. He reached down for another few drops and coated Sasuke’s lips. Sasuke took Kakashi’s finger into his mouth and sucked. His eyes crossed slightly as he twisted his tongue around the appendage. His lips were red from sucking cock, but also from the blood. It made him look more erotic.

Kakashi sat down on the bed and pulled Sasuke with him and back onto his cock. Sasuke let Kakashi dictate all the motions, pushing and pulling his mouth up and down his cock. Blood smeared around his lips transferred to Kakashi’s cock. Kakashi was being brutal and controlling only because he saw the need in Sasuke to be used. They both knew that the use of teeth would indicate Sasuke needed to stop and he could force his head out of Kakashi’s grip. He did neither.

Sasuke’s eyes clouded slightly, but not in the way of oxygen deprivation, but what looked like a drug induced trance. His jaw fell slightly and his throat relaxed even more. Kakashi kept looking down into those usually wide, glassy eyes as he used the looser orifice. Kakashi wondered if Sasuke might be slipping into subspace.

Kakashi drew his damp cock from Sasuke’s mouth. He helped Sasuke to his feet then shoved Sasuke’s face into the bed. Sasuke spread his knees, knowing what was coming.

After a moment to prepare his cock, Kakashi drove full force into Sasuke’s body. Sasuke was so slack jawed that he couldn’t even cry out coherently, just make pathetic little sounds that were merely air being forced through uncontrollable vocal cords. Then his orgasm hit and he thought he really might die; he couldn’t even moan. His torso would have slipped off the bed if Kakashi wasn’t still pounding into him.

Kakashi came shortly afterward, pressing his cock as deep inside Sasuke as he could and holding himself there as his cock pulsed and ejaculated into Sasuke’s body. He didn’t collapse on him, but he did cover Sasuke’s body with his own, much like a canine knotting his mate.

Once Kakashi got his breath back, he straightened and pulled Sasuke off the bed so that he was back on his knees. He grabbed Sasuke’s chin and stared into his eyes. “You alright?”

“Yes.”

“Good.”

He helped Sasuke to his feet. Picking up the kunai, he slit the ribbon to free Sasuke’s arms then pulled down Sasuke’s silky panties. He ran his hand up Sasuke’s abs to clutch at his chest. “Put your hands on the wall and spread your legs.”

Sasuke did as he was bid and spread out his hands shoulder width apart and leaned forward. He was well aware what Kakashi was about to do.

“Step back a little and lean forward.”

Sasuke obeyed, sticking out his ass.

Kakashi caressed Sasuke’s muscular ass, feeling the texture of his unblemished skin and preparing Sasuke for what was to come.

Using his bare hand, Kakashi spanked his former student. Sasuke jumped a little, but didn’t object. Kakashi alternated the cheek he hit, sometimes striking the center of his ass over his crack.

Sasuke’s ass was quickly turning red and the slaps hurt more and more. Kakashi stopped and caressed the heated flesh, sending pleasure up Sasuke’s spine. The gentle stroking felt extra good after the abuse. Kakashi didn’t ask if Sasuke was alright, knowing what Sasuke’s limits were. Rather, he renewed his assault.

After the second round, Kakashi did ask how Sasuke was doing as he rubbed his red ass.

“I’m good.” Sasuke’s breathing was slow and deep, not panting like he was in distress.

“Straighten up, but keep your hands on the wall.”

Sasuke’s hands crawled up the wall as he stepped closer to it, now standing almost upright, but still leaning forward.

Kakashi unclasped the bra and just let the straps hang from Sasuke’s arms. He turned and brought out his flogger. The first hits were light and thuddy against Sasuke’s upper back, sending pleasant vibrations through his lungs and ribs. This felt like a light impact massage and Sasuke loved it.

Kakashi explored Sasuke’s shoulders, back, ass, and thighs with the light strikes, just waking up the nerves and thumping the leather tails against his body.

After traveling up and down his body twice, Kakashi started swinging the flogger harder and stood a little further back so that the tips of the tails were hitting him rather than the less stinging lengths of the tails. He avoided his ass though since it was still hot and stinging.

The blows to his upper back stung, but didn’t make Sasuke recoil. The hits to his thighs did make Sasuke flinch. Kakashi stopped and rubbed his thighs. Once he soothed the sting, he wind-milled Sasuke’s back.

Next was the cane.

The thin length of bamboo stung as it striped Sasuke’s back, ass, and thighs. After every few strikes, Kakashi rubbed the marks and looked at Sasuke’s face. He looked alright, so he kept going. Yet, Sasuke’s expression never changed to one of pain. If he was in subspace, he might not realize how badly he was being hit. Kakashi stopped.

Kakashi had worked up a sweat and was breathing hard. Kakashi tossed the cane aside and used both hands to sensually rub Sasuke’s back and pressed his erection to Sasuke’s ass.

Kakashi grabbed Sasuke’s upper arms and leaned in and licked at the reddened skin of Sasuke’s shoulder blade. Then he put his hands on the wall next to Sasuke’s, lowering his body to touch Sasuke’s irritated back and ass. Kakashi’s body covered his and he breathed next to Sasuke’s ear. Sasuke found himself well and truly cowed under Kakashi’s larger body.

Then Kakashi started rocking his body, his cock sliding between Sasuke’s ass cheeks.

“Your ass is so fucking hot,” Kakashi grunted into his ear.

Sasuke’s spine nearly melted. He’d softened during the spanking and flogging even though he liked it—pain wasn’t flipping his switch right now—yet Kakashi’s actions right now had Sasuke hard and leaking. He wanted to collapse to the floor. He wanted Kakashi to grab him around the waist and just be savagely fucked. He wanted to just be passive and boneless. Most of his weight—and a bit of Kakashi’s—was on his hands. The stance was all that was keeping him up.

Kakashi could feel the tremble in Sasuke’s shoulders. He put an arm around Sasuke to hold him up as Kakashi stood up straight. Sasuke did let himself relax and he was able to stay standing with Kakashi taking some of his weight. The bra fell from Sasuke’s arms, now leaving him completely bare. Kakashi practically dragged him to the bed. Kakashi sat down and sat Sasuke between his thighs and held him tightly to his chest. Sasuke’s unbeaten skin felt unusually cool. His breathing was coming short and rapid.

Kakashi wrapped his arms around him to warm him and he waited for Sasuke to get his strength back. He touched the side of his head to Sasuke’s and nuzzled him. Kakashi was breathing in his ear. Kakashi closed his thighs a little so that the full length of his thighs were touching Sasuke’s.

Kakashi thought Sasuke had cum, but he looked down at Sasuke’s cock and saw it was still hard, though not rock hard, and there was no semen on his stomach or thighs.

“Okay?” Kakashi asked.

Sasuke just blinked and didn’t respond. Kakashi turned Sasuke’s face toward him and looked into Sasuke’s eyes. The room was mostly dark, so the dilated pupils were normal, but the way Sasuke just stared at his face made Kakashi worry a little. Kakashi pinched one of Sasuke’s nipples and saw no sign of pain. Sasuke looked down, curious about what Kakashi was doing, what he was feeling, but he seemed miles away.

Kakashi smiled; he’d brought his lover to subspace. He snuggled Sasuke into his arms securely again and rubbed Sasuke’s throat, hesitating to try to bring Sasuke back because he wanted Sasuke to fully appreciate just the state of just being, wanted him to enjoy the freedom of having no past and no worries. Something the Uchiha needed.

Sasuke’s breathing became normal as he grew aware again. Kakashi was still rubbing his body, but not sexually, just affectionately.

Sasuke groaned and looked around.

“You’re back with me,” Kakashi pronounced.

“I don’t think I left.”

“You were miles away.”

Sasuke didn’t respond, thinking back. “It felt like I was floating. Everything was distant. You were holding me against the wall and then my mind retreated.” He turned his head to look at Kakashi’s face. “Your face is really pretty.”

Kakashi smiled.

“Please, let me cum,” Sasuke whispered.

“Let’s just sit for a minute. Let me check something.” He pinched Sasuke’s nipple again. Sasuke gave a little moan. “Good. You didn’t really feel it a minute ago. Subspace can be dangerous because your pain tolerance gets really high. And you were in a trance.”

“It felt good though.”

“I know. I’ll get you off when you’re a bit more awake.”

Sasuke felt small against his body, but also warm and safe and loved and cared for and protected. “I feel really good. Just weak.”

“Rest a little and then we’ll continue. You’re too high on endorphins right now.”

“Hn.”

Sasuke took a deep breath after a few minutes and he begged again to be allowed to cum. His erection had softened, but it wouldn’t take much to bring him back to life.

“I should say ‘no’ since this is supposed to be punishment, but I want to give it to you.”

Kakashi rolled a nipple between his finger and thumb and grabbed Sasuke’s hard cock and slowly stroked him. His arms were around him and his body close. Kakashi’s scent filled Sasuke’s senses and his body heat was intoxicating.

“Please, Kakashi.”

“Release would be so sweet right now, wouldn’t it, Sasuke-kun?”

Sasuke let out a heavy, lustful sigh and tilted his head back, but he couldn’t see Kakashi’s face, but Kakashi could see most of his. “Please. I’m so sorry for what I said. Please let me cum. Please, sir. Master.”

“Alright. You’ve been a good boy.”

Kakashi twisted Sasuke’s nipple and quickened his strokes. Sasuke came hard, crying out as his semen was milked from him, his hips bucking into Kakashi hand. He collapsed in Kakashi’s arms. Kakashi looked down at him with affection. He loved Sasuke wholeheartedly.

But he was still hard and his lover was not quite with it right now, having fallen into an orgasmic trance this time.

“That was incredible,” Sasuke whispered after a minute.

“Rest a little. I’m still hard though; you think you’ve got a little left in you? If not, I can manage.”

“I can go another round; just let me reload. That really was amazing.”

“You’re amazing.”

Sasuke smiled. But Kakashi was struck by how out of it Sasuke looked, his eyes were blurry. That made Kakashi swell with pride.

Sasuke finally woke up enough and stood to crack his back. He turned to face Kakashi with more life in his eyes now.

Kakashi stood as well and pushed him down by the shoulder and Sasuke took Kakashi into his mouth. After all he’d done and seen tonight, it didn’t take long for Kakashi to get close. He growled and pulled Sasuke away and sat Sasuke down on the edge of the bed. Sasuke laid back and Kakashi picked up his legs and shoved his cock into him.

No playing, not even love making, Kakashi just fucked him. As he got close, he looked down and noticed that Sasuke wasn’t hard, but he was still enjoying it. Not needing to wait for his lover to cum as well, Kakashi thrust harder and emptied his cum into Sasuke’s body.

After a few moments, Kakashi disengaged and knelt to lick at the cut and suck it to make it bleed again. Sasuke threaded his fingers in Kakashi’s hair while the older man tongued the slice he’d made where no one else should ever see it.

Sasuke’s hands stilled as he came down. Kakashi pulled him properly onto the bed and snuggled up next to him.

Sasuke didn’t know why he started to cry, but he put his head on Kakashi’s shoulder and let go. He was crashing. Kakashi caressed his face and let him cry. It was the emotional downside of achieving subspace. He pulled the blanket over them and mussed his hair.

Eventually, Sasuke calmed. Kakashi uncovered them and eased Sasuke to his stomach. Kakashi fetched a few things from the bathroom and quickly retuned. Kakashi wiped them both down, cleaned the cut, and bandaged it. He moved over Sasuke and gently massaged Sasuke’s aching shoulders.

“You were perfect,” Kakashi said. “So beautiful and sexy. I’ve never seen so much in your eyes before. Anyone’s eyes.” Sasuke was silent, which concerned him. “Are you okay? You want to talk?”

“Keep rubbing,” Sasuke mumbled.

Kakashi obeyed. He hadn’t thought Sasuke would crash that badly or even enter subspace like that. For whatever reason, Sasuke had begun with an emotional state that let him fall into subspace for the first time.

Once he massaged the skin red, Kakashi laid on his stomach next to his lover, keeping a supportive hand on the center of his back.

“Okay?” Kakashi asked again.

“I just feel so sad,” Sasuke mumbled.

“First post sex crash?”

“Yeah.”

“Not unusual. I’m here for you. I love you and that was amazing. You are amazing. Ask me anything you need. I’ll get you water or something to eat if you want. Want clothes? Anything?”

“I’m okay. Just depressed.”

“I’m sorry.”

“Don’t be. It felt amazing.”

Kakashi came closer and molded his body to Sasuke and put his arm over him.

“I feel like a slut for liking it so much,” Sasuke whispered.

“You’re not. Well, you are for me. You don’t mind the cut do you? I’ve never marked anyone like that before or done blood play. I want to fully possess you. Collar, marks, a scar . . . I just need to mark you and make you mine forever. As long as you don’t go to anyone else for pleasure, you’re not a slut.”

“Thanks. I don’t mind the cut. That was really good. Just don’t go anywhere for a while.”

“I won’t. I’m here for you.”

Sasuke hummed and slipped off.

-----

Kakashi didn’t even get up to take a piss. He waited until Sasuke woke up, but Sasuke pushed away from him to get up and go to the bathroom. Kakashi waited until the shower started to slip in and relieve himself. He got dressed and went to make breakfast. Sasuke looked grumpy when he came to the kitchen, but he normally did.

Kakashi watched him and Sasuke ignored him. Kakashi wanted to ask him how he was and what he could do for him, but Sasuke seemed to want silence and distance right now.

Sasuke was fully dressed and he walked toward the door.

“You okay?” Kakashi asked.

“Yeah, I just need a walk.”

“I’ll stay here if you need me.”

“Hn.”

-----

Sasuke wandered the village, keeping to the outskirts and avoiding the busy streets. He’d been through a lot of emotional trauma, but this was the first time he didn’t have a reason for being depressed. He gathered from what Kakashi said that it was chemical, but that didn’t help him deal with it.

He’d strapped on his weapon pouches and grabbed his sword purely out of habit. It didn’t matter if he was in his home village; he was uncomfortable not being armed.

But being armed, he thought he might feel better after a spar. Kakashi would hold back, concerned for his state of mind and would pull his punches even more than normal. Sakura didn’t have the skill to challenge him. Sai was an asshole and he didn’t know Yamato well. Sasuke headed for Naruto’s apartment.

Naruto answered his door munching on a mouthful of ramen and one noodle hanging from his lips. Sasuke’s smile didn’t reach his eyes or lips.

“Is it too early to ask for a sparring match?” Sasuke asked flatly.

Naruto swallowed. “You want to spar on our day off?”

“I’ll go find Neji if you don’t want to. He’s more powerful than you anyway.” He turned around to leave.

“Hey! No, I’ll show you who the most powerful is! I’ll meet you on training field three!”

“Sure, Usuratonkachi.” He let a small smile escape while his back was still turned.

-----

They didn’t go all out, of course, but Sasuke put Naruto into the ground. His spirits were lifted. The fight and Naruto’s ridiculousness really did hit the reset switch on his emotions. The activity flushed his system.

He left Naruto barely conscious on the training ground and went home to find Kakashi who was still there like he promised, sitting on the sofa, napping. He dumped his gear by the door and sat next to him, pulling his arm up to drape around him like a scarf. Kakashi woke up and rested his head on Sasuke’s, not caring that he was dirty and sweaty.

“You okay now?”

“Yeah, kicking Naruto’s ass was therapeutic.”

“True, fighting a worthy opponent always feels good. You shouldn’t crash so hard the next time.”

“As long as I can feel that high again.”

“Sorry, I really didn’t think you’d slip into subspace just from bondage and a forced blowjob. Pain isn’t the key to your lock, it’s humiliation and powerlessness.”

“What’s yours?”

“Never hit subspace; not a natural sub. Domspace, however, you get me there. You give me focus and make me feel like a god when you of all people submit to me. It’s an adrenaline high, like a runner’s high. I’ve dropped from it before, but I’m more experienced, so I deal with it better. It’s not as extreme as what you felt.”

Sasuke hummed contentedly.

“Your back okay?”

“Badly bruised, but yeah.”

Kakashi didn’t let Sasuke venture too far away from him for the rest of the day and Sasuke appreciated his concern.
