It might have been fair, but Fuutarou knew that if he wasn't careful with this — it would also be very anticlimactic, not to mention very painful — and painful in the wrong way.

That seemed silly in the face of it; yes, Nino had agreed to her punishment for masturbating without permission, and yes, he had agreed to deliver it with her consent, but nowhere did anyone nor anything give him license to take things too far. And while the line between a sensual paddling and abuse was undoubtedly thin, it was still there and it was eating him out. So he had to think about what he would do.

By the time they arrived at the Pentagon half an hour later, he had a good idea of what he wanted to do. As soon as they greeted Yotsuba downstairs (they had to say that they went shopping as their excuse when she asked) and took off their shoes, and then after making sure that Itsuki and Miku were in their rooms, they headed towards the second quint's bedroom. After locking the door, Fuutarou ordered his troublesome redheaded companion to strip naked. This produced an extended stream of complaints from the girl, but Nino obeyed anyway.

When she had shed all her clothes and stood there blushing, her arms wrapped around herself, her pussy moist and gleaming and her breasts full and capped with stiff pink nipples, Fuutarou filled her in on what they were going to do.

First she was to shower, paying special attention to washing her ass and pussy. Then, after toweling herself dry, she would present herself in her room for her collaring. After that, she would meet the paddle. Thirty blows, delivered at his discretion and at whatever strength he desired to use. While she showered, she was also to think of a safeword.

"Once I put the collar on, I don't want to hear you complain. Understand?" Fuutarou told her, his voice loaded with the firmness that he usually used while in tutor-mode, but loved even more by his girlfriend during their private time.

Nino nodded, her face set despite blushing slightly. "Okay. No complaining. Anything else?"

"Nothing for now." He was pleased that she was taking this seriously too. It would be less of a hassle this way. "Go shower. You have fifteen minutes. For every minute that you keep me waiting after that, I will add another ten hits to your count."

As she left with a towel around her body, he couldn't help keeping an appreciative eye on her. Nino always made an impression leaving a room, particularly when she was butt naked, her cheeks moving up and down — taut, round, and creamy.

"They won't be like that much longer," Fuutarou thought. He was still amazed that Nino was letting him do this, but, of course, he was also aware of the trust she was placing on him. She was literally putting herself in his hands, and she only proved her words when she agreed to put on a collar that he bought.

Fuutarou had to admit it made him a little nervous. He could have started her punishment right away, but sending her to shower bought him — and her — a little longer to build the anticipation and settle themselves for what was coming. That, and he wanted to have her after she was done showering, when she was cleanest and freshest and smelled of her body wash.

While Nino was busy doing her thing, Fuutarou went about the other preparations. He'd already figured some things out; it wouldn't do to try to improvise everything at the last moment. He went through the shopping bags and retrieved the collar, placing it on top of his girlfriend's dresser. He then brought out the paddle that they kept hidden under her mattress.

Scarcely two minutes before her time was up, Nino emerged from the bathroom, toweled dry but still slightly damp in places, her loose hair falling disorderly down her back and shoulder, head bowed to hide the obvious red on her face. She walked up to her room where Fuutarou was waiting and presented herself to him, dropping her towel to the floor. Her eyes instantly fell on the collar, but then she saw the paddle. Fuutarou watched her bite her lip, and marveled at how subdued and naturally beautiful she seemed.

"She's had time to think," he imagined. Maybe she's having second thoughts? Maybe she doesn't want to do this after all?

Fuutarou had to be sure before he does something he would regret. "If you want to back out, now is the time. I'm still not forcing you to do this."

"As if I ever would back down," Nino replied, lifting her head. "You know me better than that. You told me not to touch myself. I touched myself. You caught my hands in pants. This is the price we agreed on."

He nodded. "I know. I also know you are stubborn, but I trust that you won't make me do something you don't want to do."

"No, it's fine," Nino tried to sound confident. "If it becomes too much, I'll… I'll just say it. My safeword is 'Please'. I don't want to make it any more complicated. Is that good enough for you?"

Fuutarou nodded, knowing he would have to trust her to stop him in case things went too far. He picked up the collar. "Okay. Turn around."

She was blushing a little as she did just that and lifted her hair with her hands, showing him not only her smooth back and lovely ass but also the base of her neck, normally hidden by her long red hair. The skin was still a bit damp there.

Trying not to stare at her too much, Fuutarou stepped behind her and carefully slipped the collar around her neck. He took the loose end, worked it through the double buckle until the collar was just tight enough to press on the skin but not enough to actually put pressure on it, closed the buckle and pushed the remainder at the end under the two loops so it wouldn't flap around.

A dog collar it might be, but on her it looked stunning. Two inches of tall purple leather banded her neck, with the gold buckle giving a nice accent. The height made it seem a little more severe than Fuutarou thought it would, which was perfectly fitting all things considered, and when she turned back, he noticed the small bone-shaped tag nestled perfectly in the hollow of her collarbone. A bone in a bone.

"It looks good," he told her.

Lifting a hand, Nino touched her fingers gently to the collar, an embarrassed but strangely affectionate expression on her face. She gave him a smile. "You know how to pick them, Fuu-kun," she said. "It feels different than the other one. Bigger, more restrictive." She moved her head from side to side, flexing her neck.

"Is it too tight?" He started reaching for the buckle.

"No. It's perfect."

Fuutarou was glad, and finally returned her smile. "Good."

Actually, she was much more than good, but no single word could do a collared Nino Nakano justice, so he slipped his arms around her and drew her close and kissed her. Nino tensed at first, surprised, but soon had her hands in his pants and her tongue in his mouth.

Yeah, he liked the collar. He liked it a lot. She clearly liked it too, judging by how she was squeezing him.

"Thanks for letting me do this with you," he told her when he broke the kiss a moment later, though he kept her close, feeling the warmth of her body through his clothes. "It means a lot."

"Are you talking about the collar, the paddling, or the regular fuck sessions?" she smirked, humor in her voice.

"Is there an option for all the above?" He let his hands drift down her warm body and squeezed her ass, but since she was wearing his collar now, technically it was his.

Her pussy belonged to him.

Her breasts belonged to him.

Nino belonged to him.

Neither of them wanted it any other way.

"Are you ready?" he asked.

"Yeah. I don't like owing things to people," Nino said. Fuutarou relaxed his embrace and she pulled back, then looked around her room. "So… um, where and how do you want me?"

Fuutarou grabbed the paddle from the mattress and pointed to the latter afterwards. "Kneel over the edge and spread your legs."

Nino dropped down and draped herself over the edge of the mattress, thrusting her plump bottom out towards him. Fuutarou found it hard not to stare. Other things were quite hard as well, but he tried not to focus too much on that.

"What do I do with my hands?" Nino asked. She sounded a bit uncertain but her face remained determined. It eased some of Fuutarou's own doubts.

"By your head, on either side," he told her and she obeyed. "Make sure you can say your safeword when you need to."

"Yeah, this is good," Nino confirmed, settling herself on the soft bed comfortably, with both palms on either side of her head.

Fuutarou kneeled behind her, slightly to her right so she could see him without too much difficulty, his hand tightly wrapped around the paddle's leather handle. "Remember, I'm trusting you to tell me if I go too far."

Nino smiled. "I know."

"You're beautiful like this."

Giggling despite what's about to happen, Nino wiggled her bottom in the most alluring way imaginable, and for a moment Fuutarou really thought he was dreaming again. He quickly shook that thought off, and whispered to himself that this was reality. Nino belonged to him in every way now, and he was about to give her a punishment she would never forget.

Shuffling closer, he lifted the paddle and placed it gently against her bottom. He watched her face as it tensed at the leather kissed her skin. "Take a deep breath," he told her. "Slowly." He heard the air rush into her lungs, her chest, pressed to the bed, expanding. "Keep count."

When she exhaled, he moved his hand back, aware that Nino was following him with her eyes, and swung it down hard. The sound of leather meeting soft, creamy flesh was like a WHACK! Nino jerked forward, gasping as her eyes went wide. She didn't cry out.

"O-One!" she said and bit her lip.

Fuutarou let the paddle kiss the skin of her backside a little longer, then drew it back again and swung just as hard as before. Now that she knew what to expect, Nino had braced herself so her body didn't jerk this time. She hissed as the paddle hit her, eyes widening from the painful surge.

"Two!" she managed more firmly, counting loud enough that her voice could have been heard throughout the penthouse if the walls weren't soundproof. Despite her determination to remain stoic, her face still very clearly showed the pain from the blow.

"Don't forget to breathe," Fuutarou reminded her. Up went his hand, down swung the paddle, and for the third time landed a solid smack in the middle of Nino's vulnerable and delicious ass. She squeezed her eyes shut.

"Three!" she counted and took a deep breath.

Fuutarou lifted his hand again, noticing the red mark quickly spreading over Nino's butt. It was not too deep yet, but he knew that would change. The fourth blow was gentler than the others. Nino gasped, but she clearly wasn't happy.

"What was that?" Her eyes brimming with accusation. "You are not wimping out on me ar— AHHH!"

The fifth swing shut her up, hitting harder than all the others, smashing her squarely on her right buttcheek, flattening it and sending her whole rump jerking upwards. For the first time, Nino cried out.

"F-Five!" her voice quivered. Fuutarou noticed her face was also turning red, which had the benefit of making the thick purple collar stand out in stark contrast with her color. Her breathing, now loud and heavy, made her throat press against the band. "Ahh…"

Fuutarou swung again, hitting the left cheek this time. Nino counted. "Six!" After taking a moment to let the paddle rub her rapidly reddening skin, he pulled it back, targeting the left cheek a second time in a row. The blow, arriving as it did on already tender and inflamed flesh, sent Nino into a string of groaning and loud gasping. "S-S-Seven!" she managed.

Again, Fuutarou paused, letting the paddle brush against her skin, now a very bright, very deep red, slowly teasing the offered cheeks. He also noticed a glint of wetness a little further down. Nino's pussy was clenched tight, like the rest of her, but still drooling with her juices.

"I'll go faster now," Fuutarou informed the naked, clearly aroused redhead. "Are you okay?"

Nino nodded, trying to steady her breathing. Her mouth was wide open, her face flushed almost down to her collarbone. Fuutarou swung, the paddle licking both crimson buttocks at once. "Eight!"

Then again. "Nine!"

Then he did only the right side. "Ten!"

Then the right side again. "Eleven!"

The left. "Twelve!"

Both together. "Thirteen!"

Nino counted every time, her voice quivering more, rising between gasps and moans and grunts of pain, her body breaking out in sweat. Meanwhile her ass turned redder and redder, almost to the point that someone could tell it was hot just by looking at it.

The fourteenth blow nearly made Nino lift her upper body off the table as she wailed. When she tried to count it, her voice was shaking so badly she could barely get the word out. "F-F-Fourt-teen!"

As his own hand started to ache, especially the wrist, Fuutarou well imagined that Nino's bottom must have been on fire by now. It was practically glowing red. When he delivered the next blow, the halfway point, he waited for Nino to count it and paused again. She was gasping hard, one of her hands clawing at the table while the other was drawn closer to her heaving chest. Her breath was loud and ragged, eyes tightly shut. And down between her legs…

"I should have put a towel under her," Fuutarou thought, having the urge to kick himself for forgetting to deal with this issue beforehand. "There's gonna be a stain after this."

A moment later, Nino's gasps became words. "F-Fuu-kun, please… please… let me touch myself. My pussy… is aching so much… let me masturbate. Please. Please. Please."

Fuutarou knew she must be desperate to beg like that — even in perverted situations, Nino could beg if it was needed and she did it with a scowl on her face. But hearing her now, looking at her face… her lust had evidently triumphed over her pride and shame. "Touching yourself is what got you in trouble," he said, liking the situation a little too much. "But I'll give you a chance. You can cum if you can do it without your hands. Remember to breathe. And say your safeword if—"

"I know. Fuu-kun, I know!"

For that, he swung the paddle without warning, just as hard as he had when he started. "AHHHH!" and for the first time, he received a legitimate, unguarded cry. "Ahhggh— fuuuuck!"

"Language, Nino," he chided her mildly.

"My ass is on fire," Nino groaned. "I can curse if I want to!"

"No, you can't. Not while wearing that collar I bought for you." Fuutarou raised his hand, the paddle high, before he remembered something important and frowned at her. "You didn't count."

Nino glared at him in return. "Ah, it was… ahh… dammit."

*WHACK!*

"Ahh!" Nino jerked up in time with the fresh strike, crying out sharply before she could stop herself. "F-Fifteen!"

"That one was sixteen." By now, Fuutarou could tell she was starting to lose focus. She was also beginning to rub her legs together. The red on her bottoms had spread all over her cheeks. Her normally clear skin looked like someone had taken a paintbrush to it. "The one you missed was fifteen."

"Fine!" Nino snapped shrilly. "Sixteen!"

Fuutarou pressed his lips together and carefully thought the situation over. "Nino, if you want to stop…"

"We said thirty," the redhead reminded him. Her eyes softened, and her body seemed to relax, slumping against the bed. "I know… you are concerned, but please. I made a commitment. I… put on the collar. It's not just about me anymore. This is what we agreed on."

"We agreed you would stop me if it became too much," Fuutarou replied, and no matter what he did to cover it up, his voice sounded worried.

"Fuu-ku— Fuutarou, we agreed I would say 'Please'." Nino pushed herself higher so she could turn to look at him more fully. His eyes met hers, and while he saw a whole mess of emotions there, ranging from lust to outright pain, he did not see someone who was surrendering. "When it's too much… I'll do that. Not before. Don't you insult me by quitting on me."

"I don't want you to be too—"

"I won't get hurt. I'll stop you before that happens." She laid herself back down on the mattress and squeezed her thighs together, crossing her legs at the ankles. "Now carry on, Fuu-sama."

He liked— no, he loved the sound of that, and not just because it was her saying it. It was also pretty embarrassing. He raised his hand again and sent the paddle whistling through the air. This time the SMACK was followed by an open moan. Nino thrust herself forward, grinding against the bed with her thighs rubbing.

"Seventeen!"

*SMACK!*

"Ahh— Eighteen!" Nino grunted from the pain but kept rubbing herself into the bed, and Fuutarou could see her nipples flattening on the sheets as she extracted every ounce of stimulation from her body.

He kept the next two blows at roughly the same strength, delivered one to the left cheek and one to the right cheek, both of which were bruising quite noticeably, starting to shift from red to something darker. Nino counted the blows, but between the gasps of pain and her labored breathing, there was no mistaking the look of pleasure on her blushing face.

"She's going to have marks after this," Fuutarou thought, and tried not to feel too guilty about it. Nino was literally writhing now, driving her thighs together to create as much pressure against her pussy as she could, toes curled from the mix of stinging pain overwhelming her backside and the clearly rising tide of her approaching climax.

Nino took the next few blows in stride. He swung the paddle, aiming for the middle of her bottom, trying to spread the strikes evenly across her already tomato red butt. Each time, Nino moaned, driving herself forward as she counted, back arched and thighs so tightly squeezed it would have been impossible to get so much as a pencil between them. Fuutarou could almost see the force of impact ripple through her body, spreading out until it reached her pleasure center. By blow number twenty-five, he noticed she'd stopped swallowing, her saliva dangling from her lips.

*SMACK!*

"Ahhh… twenty-six!" Nino called out, her voice rattling between moans. With her stomach and chest pressed flat and her body snaking along, it was like she was trying to have sex with own mattress. "Ahh… ahhh!"

*SMACK!* *SMACK!* *SMACK!*

The next three blows landed so quickly Nino barely had time to count them, but by the time number twenty-nine licked like a fiery tongue across her bottom, her body had reached its limit. Almost as soon as the paddle struck, she cried loudly, jerking upward, her mouth and eyes wide open, thrusting widely. Then Fuutarou saw the gush of clear juice from between her legs and that was when he knew she was cumming.

Fuutarou delivered the last strike while Nino was lost in the throes of her orgasm, and with all the moaning and thrashing, she barely seemed to notice. Her beautiful form jerked spasmodically, spraying her thighs and the carpet with the liquid of her passion as she rode that wave until it broke. And once it was done, she collapsed onto her bed, her hair sticking all over her face and mouth and eyes, panting so raggedly Fuutarou worried the collar might be getting in the way of her breathing.

He quickly set the paddle down, ignoring the ache in his hand and arm, and moved in around Nino, pulling her hair back so he could see her face. Her eyes were lidded and full of tears. Her cheeks were wet, her mouth open and her throat pushing against the white band of the collar. But when he reached down and tried to undo the buckle, she squirmed away.

"N-No…" Nino groaned, her voice low and husky. "I'm… it's okay." Her eyes met his, and she smiled. "That was… thirty, right?"

Fuutarou nodded with a smile.

"Good." Nino tried to push up, but she was too worn out. She dropped back down. Fuutarou caught her, putting both arms around her, above and below her breasts, heaving with their pink little niples scratching the air.

Leaning back, he let Nino shift her weight on to him. The moment her bottom came into contact with the floor, however, she yelped and rapidly hurried to turn herself over to her side. Looking down at her, Fuutarou could already see some of the expansive red marks he'd left on her turning slightly purple.

He let her rest there for as long as she needed, her arms tucked in, her face pressed to him. As his own heartbeat settled to its normal rhythm, so did Nino's breathing. And he couldn't help wondering about how vulnerable she looked right now. More than letting him see her naked, maybe even more than spanking her, showing him — or rather, allowing him to witness this side of her was the true mark of her trust and feelings for him.

After a while of just breathing and hugging, Nino stirred again, and when she tried pushing herself away, he didn't stop her. "It's going to bruise, isn't it?" she hissed in a low voice.

Fuutarou knew the question was rhetorical, but he nodded anyway.

"I guess I'll have a souvenir for the next few days." Nino shifted onto her knees, careful to keep her bottom off the carpet, and sent a hand between her legs. Pulling it up again, she saw it was glistening with her secretions. Then she turned her head and sure enough, there was a wet spot on the floor. "A towel next time?"

"Probably," Fuutarou said as he stood up. "How are you feeling?"

Nino made an annoyed face. "How do you think? It's like I got my ass kicked." She raised her hand when he began to open his mouth. "And don't even think about apologizing. I won't have it. This was punishment, remember? Punishment I earned. It didn't even hurt that bad near the end."

"Yeah, you were too busy trying to have sex with your bed," Fuutarou thought. He refrained from saying that. Instead, he gently raised her face to his and placed a gentle peck upon her lips. "You took it like a champ," he praised, earning a blush rising on her cheeks.

"You did well too," Nino replied. "Maybe you should join the baseball team."

With a smile, Fuutarou glanced back at the puddle on the floor. There was a strange sense of satisfaction in knowing he'd done that to her, or rather, made her so desperate she'd been willing to do it to herself, but with all that had happened he forgot an important detail. Another kind of satisfaction. Of course, his preferred method was not available due to her current situation.

He could just order her to suck him off, like she did before whenever he didn't want to use her pussy. However, one look at her bottom, now going purple, brought a swift end to that line of thought. Nino had already shown him more trust and willingness than he wanted to ask so anything more felt excessive and unfairly demanding. It also ignored the fact that she clearly needed a break.

Unfortunately, she had noticed the look that he was giving her and it wasn't something she would pass up on.

"You know, I can tell you want me," Nino said, ignoring the pain in her backside and began grinding herself against him, her groin against his, very clearly feeling his erection poking her through his shorts. Fuutarou had made no effort to hide it either. "So why not just do it? It's not gonna be any worse than the paddling. Plus, wouldn't you want it? Me being completely at your mercy, begging you to fuck me while you pound into me with this dick of yours~?"

"You're right," Fuutarou told her, smirking when he heard her gasp after he grabbed her back and pulled her even closer to him, even moaning when he willingly grinded against her. "I want you. You have no idea how much. That collar's been driving me wild. But I just went through being a nervous wreck after you had that check-up earlier. How can I be sure that we'll be safe this time?"

Nino shot him a serious look. "I told you, didn't I? I know my body better than anyone. I told you that I wasn't going to be pregnant the first time we did it, and I was right. Right now, I'm asking you to just do it but you don't want to because you're feeling nervous. Why can't you trust me, Fuu-kun?"

Fuutarou felt a pang in his chest upon hearing that question, and he couldn't help but ask himself the same thing. Why couldn't he trust her regarding this stuff? It's not like he was a girl to know about menstrual cycles and his knowledge only goes as far as the textbook definition. He didn't even know about Nino's cycle and when she's on her period.

In other words, he had nothing to say.

He sighed in defeat, looking down for a bit before lifting his head to face her. "Fine, I'll trust you, but… well, isn't this a bit unfair after what you went through?"

"Unfair? Why would you give a shit about unfair, when I'm completely yours~" The grin she gave him was mischievous, and full of purpose — Nino always had purpose. She ran her hands down to his erection before she slid down to the floor between his legs. Fuutarou didn't need to be a genius to figure out what she intended, and it became clear once she tugged the front of his pants up and over the bulge of his erection, soon to be followed by his underwear. He quickly removed his jacket followed by his shirt, as he stepped out of his lower garments. Now he was just as naked as her.

Wasting little time, Nino stood back up and meshed her lips against his in a hot kiss, with her boyfriend pulling their bodies closer to each other. Their tongues clashed in a wet battle, trying to suck each other to the best that they can. While this was happening, Fuutarou's hands had shot up to grab her large mounds, squeezing them in his grasp and rolling them in all directions.

Nino made no effort to hold back her moans. The pleasure sparked like a sudden electrical current, and only intensified as Fuutarou found her stiff, hard nipples and played with them as he wished. This girl and her body belonged to him, and he was taking advantage of that privilege.

The girl was so overwhelmed with the combination of the lingering pain in her butt and the pleasure she received from Fuutarou playing with her body that she didn't notice she was being pushed towards the bed.

She wasn't able to notice because Fuutarou had pushed her ever so gently and even guided her body so that she landed on the soft mattress as if she was a glass that would break at the slightest fall. Nino felt nothing more than a little jolt of pain as her stinging red ass met the bed.

When she finally opened her eyes, she only saw Fuutarou hovering above her, his eyes looking down on her as if he was piercing through her soul. His cock was already waiting outside her dripping entrance and without hesitation, he pushed it inside.

"A-Ahh! You…You're already inside me~!" she gasped, her pussy being filled by her boyfriend's meat as it sent massive waves of pleasure straight to her brain. Fuutarou didn't waste any time and began to move, pulling out for a bit before thrusting into her again and again.

This was completely different to the other times that they've had sex. Normally, Fuutarou would just fuck her hard and be rough with her since that's what she always wanted — and he liked it too — but this time, he wasn't like that. He moved at a gentle pace, not too slow nor too fast, because she had just went through a harsh punishment and he didn't want to hurt her too much.

Words didn't need to be said between them; the way they looked into each other's eyes did the talking for them like they knew what the other would say. All of a sudden, Fuutarou raised his hands for her to see and Nino immediately knew what he wanted.

Despite being overwhelmed with pleasure, Nino lifted her hands weakly from the bed and clasped them with Fuutarou's. He squeezed her soft hands within his grasp, as if to say that he was here with her and he wasn't going anywhere. Nino managed to flash a smile through her lust-filled gaze, which the young man found too sexy and alluring to ignore.

Fuutarou dove down and claimed her lips, starting a heated liplock as he continued to move at the same pace. Nino tried her best to keep up with him, but could only manage to meet his tongue while he invaded her mouth, losing the battle almost immediately. In spite of the pain she still felt in her ass, she was slowly forgetting it due to the overwhelming pleasure brought by Fuutarou's actions, like everything else didn't matter right now.

Nino's moans only served to fuel his growing arousal, as well as his impending release. Fuutarou kept his lips on hers, not wanting to be anywhere else while he increased his pace slightly, pistoning in and out of her pussy. Nino couldn't do anything else right now but wrap her legs tightly around his waist and keep Fuutarou close to her, not wanting to feel him anywhere else but inside.

"MMMMNNGGGGMMMHHH!" Nino moaned loudly in his mouth as she felt him suddenly explode and release his load into her waiting cunt, painting her inner walls white and again marking her as his. His hot milk sloshed around in her cervix and remained there for a bit, before his cum began to leak out of her entrance. Three minutes surely haven't passed yet, but perhaps this was just a clear indication that he really couldn't resist her even while she was being punished earlier.

His arousal mostly gone, and the high of orgasm quickly receding, it didn't take long for Fuutarou to finally pull away from her lips and stare into her eyes. Both of them were left breathing heavily, Nino more so than him.

"T-That was… so good…" she smiled, as the two shared another kiss.

Slowly, Fuutarou pulled out of her cunt and sat beside her, brushing a few rogue strands of hair that got in her eyes. "Really? I thought I should be gentle for once because you just went through thirty swats with the paddle. I didn't want your ass to hurt a lot more if I fuck you as the same pace I've always done," he confessed, rubbing the back of his head.

"Well, it's not bad…" Nino said with amusement in her tone, taking a moment to think about it before she gave him a sultry smile. "But I like it better when you're rough with me and take charge.

He heaved one big sigh, his eyes drooping down as he looked dismayed all of a sudden. "Guess I've been an idiot for so long, huh?" he asked himself in a rhetorical manner. "Even though I've done these things with you, it still felt wrong."

"Huh?" Nino blinked at him. She slowly sat up beside him, wincing as her weight was suddenly shifted to her stinging red buttocks. A trail of his cum leaked out of her cunt. "What are you talking about? You haven't done anything wrong, Fuu-kun."

Feeling a bit strange, Fuutarou reached out his right hand and traced his index finger along the raised ridge of her collarbone, but his eyes fixed on her collar. She was so close he could smell the sweat on her, the scent having totally replaced that of her soap, and he was sure she could smell him.

"No. I did plenty of wrong things." He kept his fingers moving on her skin. She leaned closer, letting him brush back hair from her eyes. "If I hadn't found your diary, I would have never understood what you wanted. How you felt. I couldn't have understood you without it. You had to wait. I know that must have hurt."

"Fuu-kun, we're naked on the bed, is this really the best—" but she knew from looking at his face, his skin slick with sweat and eyes heavy with concern for her, that he was serious. Plus, this was exactly the best time to talk about this. She took a deep breath and placed a hand on his warm thigh. "Look, I'd be lying if I said it didn't hurt," Nino admitted, looking away. "But I'm glad you found it in the end." She lifted her other hand and touched the purple object around her throat. In daylight, the clear plastic jewels looked almost golden. "I'm glad that you helped me with this. And not just with sex. There's… other things about me that I didn't put in the diary. You've helped me deal with those, too."

"Will you tell me?" Fuutarou still wanted her to know that she could talk about anything, not just sex. And anywhere. He was willing to listen. He was her boyfriend, and it wasn't a mere label. He was there for her.

Nino gave him a reluctant smile. "It's a really painful thing for me to talk about…" She averted her gaze, unable to meet his right now. "Back when we lost Mama, I made a promise to my sisters. I promised that no matter what happens, we'll always stay together as a family. That didn't really turn out well as I imagined, because we started taking up different interests while growing up and while I didn't see anything wrong with it, I also felt scared that we might not be together anymore if it goes on."

He cocked an eyebrow at her and threw her a look that seemed to ask, 'are you stupid?'. "Well, that's just stupid. You can't really stop your sisters from growing up, you know."

She shifted her gaze back towards Fuutarou to give him a frown. "I know that now, so don't remind me." She remained like that for a few moments, before going back on topic. "Anyway, while everyone else had their own stuff to keep them busy and happy, I was just alone, thinking of the past when we were all still together. I had no one with me, except when it's our birthday or when we're out on a trip, or the anniversary of Mama's death. It's the reason why I started masturbating back then during our first year. It was the only way I could keep myself satisfied and happy while I was all alone."

Fuutarou blinked, completely caught off guard from hearing such a thing. "She's been alone for that along?" he thought. No wonder there had been many diary entries already when he came across it for the first time. She had been writing in it for more than a year now. He also felt more of his guilt eating him out upon hearing that Nino only had masturbating to keep herself happy, and she's been like this way before they met…

"Believe it or not, masturbating kept my thoughts under control and if I didn't learn about it, maybe we would still be at each other's throats until now." Nino took a deep breath and finally turned to him, a thoughtful expression on her face. "When I first learned about you, I didn't want you around us. I didn't want you around my family. I knew that if you were around, teaching everyone and all that, my sisters will just grow up even faster and we'll be separated for good when that happens. But you know what happens after that, right? You read the diary."

"She wrote about me because she didn't want to be alone anymore," Fuutarou thought. Even on days where they didn't fool around with the diary, she was beside him, spending time with him and enjoying his company. During the nights that he spent here before their midterms, she was with him, letting him sleep in her bed, warm under the blanket or in his arms. More than once Fuutarou had thought he was dreaming whenever it happened. How could he not? It was so surreal.

It was funny; he'd gone into HER room the first time to get back something that belonged to him and instead ended up getting her to belong to him as a result. Now he was spending a considerable amount of time in her room almost everyday for various things, and they were both visibly happier for it.

"Are you staying over tonight?" she asked sweetly, moving on to another topic because there was no need to dwell on what they just talked about.

He shook his head, smiling. "Maybe for the finals. For now, I'm back to spending afternoons here before going home for the evening."

Nino nodded, but she did give him a knowing smirk. "I'm gonna be really lonely here, you jerk. Maybe you can sneak in here tonight? I'll open the door for you then we can have some fun while we're alone~"

Fuutarou laughed. "Your father would have a fit if he finds out. Also, we'll meet again at school. We'll just have to be away from each other for several hours."

"Oh, come on… please?" she leaned against him, giving him a pair of puppy-dog eyes that were near-impossible to resist. Keyword, near. "I guess I'm just going to play with myself and send pictures of it to you, then~"

Fuutarou laughed again, this time louder than before. "Ah, now, you are just begging for another spanking. How's your ass?" he asked out of concern.

"I expect it's turning purple by now," Nino said.

"Purple like a grape or purple like an eggplant?"

"You tell me." Nino shrugged, then lied on her right elbow and side enough so he could see her backside. The sight made him cringe slightly. Not only had a large area of skin turned purple now, he could actually see individual strokes of color where heavier blows had landed on her flesh. Around this, there was a lot of red.

"She was doing this for me," Fuutarou thought. To show she is serious.

He still felt guilty, but now a little admiration also seeped in. She took all of those hits head-on, and not once did she give up. Her will and determination were aspects about her that truly stood out among the others. If it was him in her place, he was unsure if he would be able to last all thirty blows.

"So which is it? Grape or eggplant?" Nino prompted, looking back over her shoulder and trying to see her own ass. She reached down a hand, but as soon as she touched one of her cheeks, it made her hiss loudly. "Ahhhshh! Oww…"

"Both," Fuutarou said, and brought her up to sit again before hugging her, being very, very careful to avoid her bottom. Nino tiredly eased herself into him with surprising readiness, and seemed quite content to remain in his arms for the rest or the day.

Unfortunately, both teenagers also knew that they would have to bid farewell soon, because Fuutarou still needed to go home and the next time they meet would be tomorrow. They should let out everything they wished to say now before saying goodbye.

"I guess I'll need an excuse for how I'm gonna act in class tomorrow," Nino stood up and faced her towards the mirror next to her cabinet and looked over her shoulder to inspect the damage done to her precious butt. "My ass is gonna sting so much while I'm sitting on my chair. Heh. Everyone's gonna be so weirded out when they see me shifting around in my seat."

"Maybe you can just say you're sick or something," Fuutarou suggested. He quickly wiped both the bed Nino had laid on for her punishment and the floor he'd spotted with their orgasms. It was already noticeably sticky but of course, the only way her sheets could be cleaned would be a trip to the laundry. "Oh, and you should wear panties tomorrow."

"Yeah, that sounds like a good idea," Nino looked at her butt in both amazement that Fuutarou did this much to her and pain because it really hurt whenever her skin came into contact with something else. "I wasn't thinking the bruises would be this bad."

A look of worry flashed through his eyes. "Staying home entirely would be better." Fuutarou could already imagine the agony sitting on those hard wooden chairs would cause Nino's tender, aching butt. "It wouldn't be fair to have you go to school after this. I could be here with you too, because… you know, since it was me who—"

Nino heaved an exasperated sigh and turned to him with a frown. "Are you still feeling guilty?"

Fuutarou finished cleaning up and tossed the tissues into the nearest bin. "Of course. How can I not feel guilty? Look at your butt."

"Fuu-kun, if you don't stop it I won't let you do something like this again," Nino told him firmly. "I mean, I understand why you feel that way, but you don't have to. It was a punishment we agreed on. You shouldn't feel guilty over something we both wanted. And it's not like I want you to be afraid to call me out when I break the rules."

He understood that, he really did, but he could only wince every time he saw the color of her ass. "I think maybe next time, I'll just use my hand," Fuutarou said thoughtfully.

"What about a belt?" Nino suggested in a helpful voice th!at was, in point of fact, very unhelpful. "A cane? A whip?"

"Oh boy," Fuutarou thought. This was really going to get out of control if he didn't set limits. And now was as a good a time as any.

As Nino turned her head to follow, Fuutarou circled around behind her and got on his knees. At first, she seemed confused, but when he brushed her hair away from her neck and reached for the buckle of the collar, she realized he meant to take it off. She tilted her head in the opposite direction to give him better access. Fuutarou worked the end of the collar back through the buckle and the whole thing tugged loose.

"You know, I can just wear it 'til I have to go out," Nino said, but not in her usual whiny tone.

"If you wear it all the time then it means less," Fuutarou told her. "This is for us. When we want to… do serious things. If you just want a collar to wear all the time, you can use the old one. But right now, though, I think you should relax. Are you messy down there? Want to wash?"

"Not as messy as I would like." Nino rose to her feet anyway. "But fine. I'll go clean myself up because you said so. I can still feel your hot milk leaking out of my pussy," she said nonchalantly, making her boyfriend blush slightly.

It was Fuutarou who left the room first so as to not create any suspicion about what he and Nino were doing inside, especially if the other girls see their sister leaving with a towel around her while he was still inside. Once Fuutarou was downstairs, assisting Yotsuba, Itsuki, and Miku in their homework, Nino made her move. She went straight to the bathroom with her towel while nobody was looking. When asked why she had taken a shower again afterwards, she just played it off and stated that she forgot to clean a certain spot.

Ichika finally arrived home while the second sister was preparing dinner, and she looked really tired that she wanted to retire early and sleep for the rest of the night. Of course, she wasn't allowed to do that because she still had homework to attend to.

During dinner, Nino was strangely quiet. She didn't say a word, nor did she answer any question that was asked to her by her sisters. She only responded to them by gestures, as if something was bothering her deeply. She insisted that nothing was wrong with her and told her sisters not to worry but Fuutarou, who was at the couch watching their interactions, couldn't help but do just that. What was going on with her?

By the time that he was preparing to head home, Fuutarou saw Nino walk down the staircase and head towards him with her head hanging low. He was actually hoping for her to show up so they could have a little talk before he leaves, and this was his chance. "Nino, is something wrong?" he asked.

She shook her head furiously, sending a storm of long red hair in every direction. But she didn't answer.

"Is it your butt?" He had no idea what to do when she wouldn't even give him a verbal answer. The only thing he could do was make the right guess. "Is it hurting?"

Nino shook her head again, releasing a heavy sigh. "I can't hold back anymore," she said. A faint pink bloomed on her cheeks as she looked up at him. "I can't."

"I don't understand." Fuutarou said, confused. "You can't hold back? What does that mean? Are you angry with me? I thought we were doing good."

"It's not that, it's…" she trailed off, the uncertainty clear on her face.

"Then what is it?" He was starting to get worried. "Are you upset about me not staying over for the night? Or is it the paddling? I did it too hard, didn't I?"

Nino shook her head. "It's not that either." She took a deep breath, and finally seemed to make up her mind. "Fuu-kun, listen. There's still some things about me you don't know, and I want to tell you those things. But you should know this. Ever since Mama died, I tried not to need anyone. Despite how lonely I felt and how much it frustrated me that I could only play with myself to stay calm and how I needed a diary to let out what I feel. After meeting you, though… after being around you, I knew there was something different. I started including you in my diary, and I also used it to get some things off my chest. But I don't want to be a person who depends on others. I don't want to need others."

"People aren't meant to be alone, Nino." Fuutarou felt a pang in his chest upon saying that — and even more that he knew he had to say it.

Her eyebrows wrinkled. "And I don't want to be, either. I hate being alone. It's what I felt when Mama died and when my sisters just grew up like it's nothing, and it felt like they were leaving me. But I also don't want to be a weak person who needs others to pamper her with everything. I can't accept that. Of course, you know by now that I'm… a girl pervert. But it was never about the sex. It was about who I wanted to do these things with. I wrote my diary so I could get all this out because these thoughts were eating me up. I never thought about what would happen to me if we actually did this. And now that you are so good at it, I think… I've become dependent on it. When you put that collar on me, it wasn't like before. It wasn't like the night you came into my room. Back then, I could still say no. And I know that I can always say no and you'll stop. But when you gave me that collar… after a while, I wanted you to never take it off."

"Ah," Fuutarou said, and he thought he was finally starting to get it.

"I tried to keep this simple. I really did. I thought it was it was only about sex and pleasure… my body understands those things. But I couldn't keep it that way for long. Every time we did it, you went out of your way to make sure I'd feel safe despite what I've written in my diary. You didn't want to go too far even if I asked you to. Still, you don't pamper me and you're not overly kind because you can do things like punishing me or buying me a collar…"

His confusion was reaching its limit, and he decided to simply go straight to the point. "Nino, what are you trying to say?" he asked.

Nino began twiddling her fingers nervously, something that made her look incredibly cute. It was completely different to her usual demeanor. "Ever since that day, I didn't feel alone anymore. Because…" She looked up at him shyly, a deep blush on her face. "…Because I love you."

His eyes widened almost immediately.

"W-What…?"

Taking a deep breath, Nino steeled herself and looked a lot more serious than before, although the blush never left her face.

"I love you, Fuutarou Uesugi."

With that, her doubts and insecurities seemed to vanish right away. She took a deep breath, followed by a step, then another, and another, and then just when she was about to kiss him, Fuutarou had grabbed her shoulders to stop her. Her eyes shot open and looked at him in confusion, as a spike of fear washed through her. Could it be that he didn't want this?

"Nino… I love you too," he confessed. "Not just because of the things we do together, but also because of what you taught me."

Fuutarou raised his hand to cup her cheek while the other pushed some of her hair behind her ear so he could see her blue orbs clearly. Both teens stared into each other quite intensely for a bit, before leaning close to her with a little smile on his face.

"It's because of you that I learned not to ignore the people around me anymore. If it wasn't for you, I would have stayed as the same dense and idiotic tutor I was back then. Thanks to you, I realized that I can balance my studies and personal stuff like romance rather than focus on one completely. You showed me what it's like to have someone that's there for you, someone who wants to be with you despite a person's faults, someone who you can depend on when you need it…" He leaned even closer that their noses were touching. "I will do everything in my power to stay as your tutor, because I want to be with you, Nino."

And the two kissed. It was completely different to the kisses they have shared so far; whereas their earlier ones were all about lust and passion in the heat of their private time together, this one was filled with emotion and their true feelings coming out into play. They didn't use their tongues at all, because it wasn't needed. It was short as well, but it didn't make the kiss any less important because they were already aware of what each other felt and this only solidified it.

As they separated about ten seconds later, they stared at each other for a while before Nino broke the silence between them.

"This is so stupid… it's only been weeks since we started dating and we're like this already?" she giggled, wrapping her arms around his neck and giving him a smirk.

Fuutarou grinned in return. "Is that a problem?"

She hummed for a bit, before standing on her tiptoes and giving him another sweet peck on the lips. "Hmm, as a matter of fact, I love it so much. I'm not one to waste time with unimportant things~"

The two were left in their own personal world afterwards, enjoying the little time they had before Fuutarou leaves. Unknown to the two of them, however, a girl was watching this unfold from the second floor, but she didn't look mad. If anything, she had an amused smile on her face watching her sister kiss Fuutarou on the lips and just being happy around each other as a couple.

"Fuutarou-kun… please take care of my sister," she thought, before heading back to her room to give the two some privacy.

The day had been long and tiresome and full of frustration and humiliation. Fuutarou had bought her a dog collar as a sign that she belonged to him and of course there was the paddling, which despite being much more painful was also a lot less humiliating. But it had also been a wonderful day thanks to the boy whom she openly admitted she loved.

When Fuutarou had picked the collar in the pet shop, she thought he was kidding, and for obvious reasons, she also thought he had no idea what he was doing. But to her shock, not only did he know, he was willing to take that chance on her. His words had convinced her, but also troubled her. It was then that she began to realize just how far they'd gone, and that, once she accepted this step, it would be very hard to go back even if she wanted.

The diary was never supposed to change her. It was meant to be an outlet for her sexual frustration and her loneliness and to remind herself of things she wanted but would, as sure as she could be sure of anything, never get. Not only had they happened, but both the diary and Fuutarou's own actions and willingness had indeed changed her. Among other things, they had made her more open and understanding, more patient, less prone to violent outbursts. But those same things also scared her. Fuutarou had become far too important, far too ingrained in her heart, and the feelings he provided were like a drug. And drugs were addicting.

When he put the collar on her, she had been afraid. Afraid of what it meant. Afraid to be dependent on someone else. Most of all, she was afraid that she would NEED him to the point where she could no longer accept being without him. And then what would she do after that? How would she sleep alone again? How would she look at herself in the mirror knowing that compared to her other sisters who grew up in other ways, she was the first among them to find someone in their life?

At first, it had been a little easier to ignore this. She had been, after all, extremely horny.

Once she had a chance to work herself to orgasm with nothing but her thighs and the impacts of his paddle, after her post-climax daze subsided, her head cleared and some of the old fears returned. When he took the collar off again, literally and symbolically setting her free from the more intimate obligations for the day, she felt like a different person. Weaker, confused, and suddenly full of doubts. That was why she had spent an hour in the bathroom thinking of the boy who made her feel like this.

Fuutarou Uesugi would never force her to do anything, regardless of how much more assertive he became. He would never force her if she truly refused. He may have acted like a jerk and an asshole at first, but he was someone who cared a lot for the people close to him. Deep down, he truly wanted her and her sisters to succeed, and that's why he was doing his best as their tutor to make that happen. He was way better in real life than the fantasies she's had about him.

Nino wasn't a smart girl when it came to academics, but she wasn't stupid when it came to social interactions. Both of them were aware of their mutual attraction, but did their feelings only involved just mere attraction? It can't be. That's why when she finally decided what the answer was, she stopped him from leaving for a bit and told him what she needed him to say.

She loved him. That was the answer. There was no other way to explain why she had given him her full trust to do these things to her, why she felt comfortable telling him about her fears, and why she agreed to be collared as a sign of belonging to someone else. Perhaps she knew that she did, even way back when he asked her to go out with him, but she only acknowledged it now. She needed him, in more ways than one. She couldn't hide it within her proud and haughty personality, because Fuutarou had broke through that long ago.

As she climbed into bed and settled on her side to hug one of her body pillows, Nino smiled fondly while thinking of her tutor. Her bottom hurt; both a blessing and a curse. A curse because it was painful. A blessing because it reminded her that Fuutarou was not a coward or wimp, and she belonged to someone who was there for her. He may not be here with her now, but Nino didn't feel alone at all. There was someone for her this time, and she couldn't wait to see him again.

Sleep slowly claiming her, she reached out and turned off the light from her night lamp. As she closed her eyes, she knew what the next entry in the diary would be.

Today, I confessed to the man I love.
