This one is a little...harsher than chapter one. You have been warned.

Miho gently sat Arisu down on the edge of the bed, put her hands on her shoulders, and kissed her. Arisu hummed into the kiss, and Miho smiled. She broke the kiss and put one of her hands on Arisu's cheek, rubbing her thumb back and forth across it. "Do you remember the safe word and signal?" Miho asked.

Arisu nodded.

*SMACK!*

Arisu nearly fell over onto the bed, but Miho's firm grip on her shoulder kept her in place. She looked back at Miho with an expression of hurt and bewilderment, but Miho just smacked her again. "I should've punished you properly yesterday for being so disobedient," Miho said. "Guess I'll just have to do it double today."

"Wh- Miho, what are you doing?!"

*SMACK!*

"Excuse me? Don't talk back to me," Miho said. She yanked Arisu off the bed, marched her over to the corner, and shoved her onto her knees. With one hand on top of Arisu's head, gripping her hair, Miho used her other hand to yank her shorts down, letting her hardening cock bob free. She eagerly stroked it, letting the sight of the red hand mark on Arisu's face and the look of fear in her eyes fuel her lust. Fully erect she laid her cock across Arisu's face, her balls on her little girlfriend's mouth. "Suck. Now."

"M-Miho, please don't-"

*SMACK*

"I told you, don't talk back to me. Do you understand? Suck me off right now, or I'll make it worse."

"M-Miho, please..."

Miho had had enough. She pushed Arisu's head back against the corner, lined her cock up, and forced it into Arisu's throat. Her girlfriend gagged and clawed at her bare thighs, but Miho ignored her. She grinned and forced herself deeper into Arisu's mouth, greatly enjoying the look in Arisu's widening eyes.

"Thhhhere we go," Miho cooed. "Much better now that you're done back-talking me, you dumb bitch." She sank her cock into Arisu's throat until she bottomed out, her balls pressed against her girlfriend's chin and her pubic mound compressing her girlfriend's nose. She held it there until Arisu started to squirm from asphyxiation and then pulled back and started thrusting, using Arisu's mouth as little more than an onahole.

Amazingly, as if she hadn't learned enough, Arisu started to resist. She groaned and squirmed, smacking Miho's thighs. Miho couldn't concentrate with her doing that, so she decided to put a stop to that. She grabbed one of Arisu's wrists and pushed in until she was suffocating Arisu again. "What did I tell you?" Miho asked. Arisu whined and relaxed, and Miho took that to mean Arisu wouldn't do that anymore. She released Arisu's hand, smacked her head, and started thrusting again. Her cock slid back and forth, gliding across Arisu's tongue, her girlfriend's lips firmly and obediently wrapped around the shaft. Her balls smacked Arisu's chin on each thrust, audibly reminding the little sub of her place.

Miho pulled out completely and stroked herself. "Need a break?" she asked, and Arisu nodded. Unfortunately for her.

*SMACK!*

Miho forced herself back into Arisu's throat, both of her hands on top of her girlfriend's head. "Haagghhhhh yeah," Miho groaned. "I can't believe you use this mouth for anything but sucking me off. Hopefully this'll be enough to remind you that it's only good for one thing."

Arisu whined and groaned, her hands between her legs. Miho looked down, noticed this, and stopped. "Are you touching yourself, dumb bitch?" Miho asked. Arisu froze, unsure of how to respond. If she told the truth, Miho would punish her. If she lied...

Miho pulled out.

"W-WAIT! MIHO PL-"

*SMACK!*

Arisu gritted her teeth, tears running down her cheek, and Miho plunged back into her mouth. "Stop touching yourself right now," she ordered, and Arisu did as told. Miho shoved herself in hard enough that Arisu's head was pushed back into the corner, trapping her completely. She put her hands on Arisu's cheeks and pulled her in, forcing her girlfriend to take very last millimeter. Her cock flared and throbbed but she managed to hold back from cumming, at least for the time being. Arisu began to struggle and writhe, her eyes watering as she was slowly deprived of air. Her fingers scratched Miho's thighs but she did not smack, because she was a good girl.

Miho pulled back, letting Arisu breathe, and then started thrusting again. The way her cock slid in and out of her girlfriend's lips made her skin tingle and her toes curl, and she panted as she went. She looked down at Arisu with nothing but lust in her eyes and Arisu gazed back, quietly taking the cock like the good girl she was. Spittle flew from her lips on each thrust, slathering Miho's shaft in saliva. Miho was close to finishing, her pace becoming erratic. She pulled out and stroked her cock eagerly, precum drooling from the tip. "In your mouth, or on your face, dumb bitch?"

Arisu looked at the cock in front of her, the wad of precum bobbing with Miho's stroking, and her stomach tightened. She licked her lips and looked up at Miho. "In, please. Thank you."

"I thought so," Miho said, and forced herself back into Arisu. "You've finally learned your mouth is only good for drinking my sperm. Is that right? Have you finally learned your lesson?" she asked. Arisu just moaned. "Have you? Hav- Ggggrrrnnn." Miho cut herself off by cumming, pumping her load straight down Arisu's throat. She put one hand on top of Arisu's head and cupped her girlfriend's chin with the other, keeping her firmly in place to ensure she swallowed it all. Like a good girl.

When she was done Miho pulled back just enough to let Arisu breathe and kept her cock inside while she recovered from the orgasm, her hands at her sides. She panted and panted, a shiver running through when she felt Arisu swallow her wad. "Good girl..." she whispered. She licked her lips, took a deep breath, blew it out, and stood up straight. "Good girl. But I don't think you've learned your lesson."

Miho pulled out of Arisu's mouth and yanked her to her feet. Arisu protested weakly as Miho marched her across her dorm to her desk, where her hairbrush was lying. She stood Arisu right next to the desk, yanked her pants and panties to her ankles, and snatched up the hairbrush. "W- Miho, wait, don't! Stop!"

Miho gave her a look. "Who the fuck said you could give me orders?" she said. She wrapped one arm around Arisu's back and forced her into a half-hug, gripping the handle of the hairbrush with the other. Arisu wrapped her arms around Miho's back and gripped her tightly, preparing herself.

"No, stop! Please stop, don't-"

*SMACK!*

Arisu yelped as the hairbrush hit her bare bottom, leaving a harsh stinging in her left cheek. Miho spanked the right one, then the left, then the right. She went on like this, alternating between the two tiny cheeks of Arisu's little bottom, until her girlfriend began to cry. "P-Please stop..."

"Shut up," Miho said, and started spanking harder. Arisu's hands dropped her sides and she gritted her teeth, trying desperately to anticipate each swat to her tender bottom and failing each time. Miho spanked and spanked her, turning her butt bright red as she did. "I have to do this because you're too fucking stupid to learn your lesson."

Arisu held back from outright sobbing as she endured her second punishment, trying to ignore the pulsing in her privates and the moisture drooling down her thighs. Before she knew it Miho's spanking was becoming lighter and lighter, telling her it was almost over. With a few final firm smacks her second punishment ended and Miho set the brush aside, using her hand to gently stroke Arisu's bottom. "There there," Miho whispered. "Good girl, good girl."

Miho let her go and Arisu stepped back, her hands behind her back. She squirmed on her feet, trying to will away the intense stinging in her little bottom. She wiped away the tears on her face and looked at Miho, who gazed back lovingly. Miho put her hand on Arisu's shoulder, rubbed it for a few moments, then raised her hand.

*SMACK!*

Arisu stumbled back and collapsed onto the bed, stars in her vision from Miho's backhand. Before she could scramble away Miho jumped on her and pinned her down, the wild look in her eyes making Arisu excited in a very deep way. One that she just could not explain, no matter how many times they did this. She felt a trickle on her lip and reached up, her fingertip coming away bloody. She looked at it and Miho with a look of bewilderment, and for just a moment Miho wondered if she'd gone too far. She gave Arisu a full four seconds to say the safe word before she continued.

"A little nosebleed never hurt anyone," Miho said, and rubbed her cock against Arisu's wet pussy. "You deserve it anyway, dumb bitch. Every time you wear that Boko onesie I get a nosebleed, so consider it payback." She moved her hands from Arisu's shoulders to her throat and squeezed. "You like that onesie, don't you? You like teasing and enticing me, you fucking braindead slut. She released one of her hands and backhanded Arisu again, flicking blood across her white bedsheets. She gritted her teeth and squeezed Arisu's throat again, making her girlfriend's eyes bulge. She released her again and used her right hand to line her cock up with Arisu's pussy, pushing it into her. Arisu gasped at being split open and looked down the length of her lithe body to watch Miho's cock sink into her. "You like watching, huh? I bet you do, dumb bitch."

"M-Mi..." Arisu whispered, one of her hands holding onto Miho's wrist. Miho once again gave her a moment to say the safe word or use one of the safe signals, but Arisu just looked at her lovingly, and Miho decided she was ready. She started pumping Arisu's tiny, narrow pussy, the pleasure at once shooting through her.

"Did I give you permission to talk?" Miho asked, and put her left hand over Arisu's mouth, using her thumb to close Arisu's nose. "Do I have to remind you what your mouth is good for?"

Arisu shook her head.

A fresh shiver ran through Miho as the pleasure mounted, and she felt her inhibitions slipping away again. When or how this had started neither of them could say, but they both deeply enjoyed it. They had their boundaries, of course, and they were freely and firmly established. They each knew the safe word and the multiple safe signals, to be used when Arisu's mouth was busy or covered. So long as Miho didn't break Arisu's boundaries, and Arisu didn't use the safe word, then she was free to do what she wanted with her little girlfriend. A fact that, at first, she had been hesitant to exploit.

But today...?

She raised her hand from Arisu's face and smacked her again, and Arisu's body convulsed. Her pussy clamped down around Miho's cock, and Miho grinned. She plunged all the way into her and held herself there for a moment. She gritted her teeth again and stared down at Arisu's red face, blood still trickling down her cheek to the pillow. Sometimes Miho just...couldn't help it. She just had to... Just...

*SMACK!*

"Worthless, stupid, bitch, slut," Miho said. She pulled out, got onto her knees, put her cock back in Arisu, and leaned down over her girlfriend's body. The way her hair hung down around her head gave her tunnel vision, obscuring everything from sight but Arisu's face. Arisu's red, blood- and tear-stained face. She could see it there, in Arisu's gaze. Trust. Something deeper, firmer, than just simple love. She trusted Miho. Trusted her to do, give her, what she wanted without going too far.

"M-Mi... I lov-"

"Did I fucking give you permission to talk?!" Miho said, and smacked Arisu again. "Really now, just what do I have to do to get the message across? Just shut the fuck up already. Tired of hearing your voice, you dumb bitch." She switched into a squatting position, using the extra leverage to piston more of herself into Arisu's sticky pussy, and put her both hands over Arisu's mouth and nose. "It's so much better when you just shut your fucking mouth and let me fuck you in peace." Another shudder wracked her body as she mating pressed her tiny girlfriend's body, completely subjugating her. Aris could do nothing, was nothing, under Miho's bigger frame.

Both of them moaned as Miho got into rhythm, pumping her cock in and out of Arisu's dripping folds. Her fluids were flicked onto the bed on each stroke, staining it darkly. Miho stared down into Arisu's eyes, biting her lip. "Why can't you be a good girl all the time, Arisu?" Miho asked, knowing that using her girlfriend's name would add emphasis. "Why do I have to constantly show you your place? Why are you so fucking stupid?"

Arisu just moaned and began to writhe. Miho's hands were pressed to her mouth in such a way that she was just barely able to breathe, so long as she took very long breaths. She was starting to feel light-headed when Miho let go for just a few moments before she covered her mouth again, the side of her hand blocking Arisu's nostrils. She began to writhe and squirm again, and Miho used her thumb to close Arisu's nose completely.

"I love you," Miho said. "I love you, I love you I love you." She was pumping harder and harder now, her hips harshly slapping the underside of Arisu's thighs. Her plump fluid-splattered scrotum smacked Arisu's butt on each thrust, smearing it in Arisu's juices.

*SMACK!*

"I love you, I love you," Miho breathed. She pressed her hands over Arisu's mouth and nose again and just focused on thrusting, getting closer and closer to her orgasm with each push. Once more Arisu began to squirm. Slowly at first, then more and more as Miho smothered her. She writhed her whole body, groaning in fear and desperation. She started unconsciously tightening her pussy, which drove Miho on and on. Stars filled her slowly darkening vision, and she screamed into her closed mouth. She screamed and screamed, which only further used up her swiftly declining oxygen.

Miho rammed herself into Arisu as far as she could and came again, squirting rope after rope of virile sperm into her girlfriend's fertile and eager pussy. As always a jolt of adrenaline shot into Arisu's system, both from the idea that she was being impregnated and from the primal fear that she was about to die, her body violently fighting for air. She was deathly afraid she was about to black out, about to reach up and press her palm to Miho's forehead, when Miho released her. Arisu took a deep, shuddering breath and started coughing uncontrollably, her body heaving.

Miho didn't notice, however. Didn't care, really. She was still coming down from the intense high of shooting her load into Arisu's sticky snatch. She put her hands on Arisu's meager boobs and just panted from the exertion, her eyes half-lidded. Her still stiff cock was lodged firmly up the entire length of Arisu's pussy, the last of her cum drooling out and into Arisu's womb. If she'd actually get pregnant, neither of them knew. She'd never once gotten pregnant from Miho.

Miho sighed, looked down at Arisu, panting for an entirely different reason, and eased herself onto her knees. She lifted Arisu's upper body up into her bosom and held her there for a few moments. When she felt like she'd recovered Miho pushed Arisu back, looked her in the eyes, and cocked her hand back. She balled it into a fist and just held it there, and Arisu stared at it, wide-eyed and fearful. Her breathing became shallow and she started to tremble, waiting and anticipating.

After a few moments, though, Miho let her hand drop. "I... I can't. I'm sorry," she said, and hugged Arisu. Arisu returned the hug but pulled away after a moment.

"What, too weak after blowing your load so quick? Really, how long was that? Four minutes? I never even came close to cumming, you impotent loser," Arisu said with a smug smirk. Miho stared at her for a few seconds, her expression blank and her eyes empty, before she cocked her fist back again.

*WHAM!*

Arisu was knocked clean out of Miho's grasp and fell back onto the bed, both hands instinctively coming up to cover her face, her eyes squeezed shut. Miho's cock popped free from her and she rolled onto her side, legs drawn up in the fetal position. She rolled back and forth for a second, unable to speak or think. Fresh tears flowed down her face and she opened her eyes, reluctantly pulling her bloody hands away from her face. "Oh geez... Holy shit..."

Miho was by her side in a second. "Oh my gosh, are you OK?!" she said, and Arisu looked up at her. Miho snatched a box of tissues from her desk and plucked some out, reaching up with them to wipe Arisu's face. Her girlfriend stopped her, though, and smiled.

"Was... Was that your best? Wow..." Arisu said. Something filled Miho's eyes. Something that Arisu had never seen before. She raised her hand and was about to slug her again when Arisu put up her hands. "Aardvark! Aardvark!"

Miho instantly dropped her hand and moved closer to Arisu. "Let me see, let me see," she said. Arisu lifted her head and let Miho wipe her face off. "It's not broken, is it?"

"No," Arisu said, and shook her head. "You were perfect, as always. The right amount of force without going so far as to leave a mark or break anything. Really, you're quite good at this. Scary good, in fact."

Miho laughed sheepishly and rubbed the back of her neck. "Thanks?"

Arisu hugged Miho again. "Really, thank you. "I love you, Mi."

"I love you too, Arisu," Miho said, and returned the hug. She wiped Arisu's face off again and, aside from the lingering smack marks, her girlfriend's face was unmarred. She took the time to clean off both their privates and then the two of them sat next to each other on the bed, arms wrapped around each other's back. "Did you enjoy it?"

Arisu nodded emphatically. "It was the best," she said, her voice a little nasally from the blood still in her nose. "I loved it~!"

"I'm glad you did," Miho said with a smile, and kissed Arisu. "Though with that last little cheeky remark..." she said, and Arisu shuddered.

"I can't wait~" Arisu said, and kissed Miho back. She gazed up at Miho with a sultry look in her half-lidded eyes. "I wonder how else I can prod you," she whispered huskily.

"Ehehe... Be careful what you wish for; you just might get it," Miho said.

"Good," Arisu replied, and snuggled up to her girlfriend even more. She gently pulled Miho down until she was on her back with Miho over her, their faces just millimeters apart. "Good..." Arisu whispered, and they kissed again. Miho turned so that she was properly above Arisu and returned the kiss. And again, and again, until the two of them were making out, half-clothed and hearts full.

Special thanks to DaniFuli for the inspiration for this one. Sexually sadistic Miho is just... *chef's kiss*
