S & M (R-18)

Ryo and Rika went back to the mansion and found everyone waiting for them to eat. Apparently they barely made it on time for dinner.

"Aahaha... sorry everyone... we kinda got too into modifying the weapons" Ryo excused himself and Rika to the others, who where looking at them disapprovingly. Thankfully, he wasn't a work addict. "Anyways, thank you for waiting for us"

After dinner, Ryo showed each girl the weapons he had made. They were a bit surprised when they saw that they functioned properly, and when Ryo explained what each weapon was made of and how it funtioned, they all got happy. He had though of the needs each of them had, instead of just jamming the blade in a gun.

Yuriko looked at hers and thought that it was simple, but she preferred it like that. She did tease him by saying she might need to re-establish her position in his heart, but laughed energetically when she saw Ryo's troubled look. Saeko and Hiratsuka were very content with their weapons, since it was a failsafe in case it was needed, rather than something they would use actively.

But there was one person who was the happiest of them all.

"This is... This is Master's first gift to me!" Miku screamed ecstatically. She was full of happiness when she saw her weapons. After all, even if they were simple, they were made specially for her. She jumped on Ryo and hugged his waist with her legs. "Master is so good! I love you!"

She got down from her hold and, with Ryo looking at the girls apologetically, dragged him away to her room.

"I'm done being patient!" she yelled agitatedly, but if one paid attention you could hear anticipation in her voice. "You're taking me tonight!"

*

Already in Miku's room, Ryo was a bit lost. He did want to take her, but he wanted to make it special for her. Then again, he came to a conclusion rather quickly. Miku really didn't care about the situation. He was pretty sure that if he ordered her to drop on her knees and blow him in the middle of the day with people watching, she would. And he was right.

"Master, I've been a good girl and waited patiently~" Miku said as she crawled on all fours towards him. When she finally was close enough, she hugged his legs and pressed her face against his crotch, nuzzling her cheek right where his dick was. "But I don't want to wait anymore~"

Ryo could feel how the girl sniffed his crotch as her eyes hazed and her breathing turned ragged and heavy. He knew she wanted to be fucked and he knew how much she liked being ordered around. She was a submissive masochistic girl.

Something snapped in Ryo's mind when he saw her begging look.

"What are you waiting for?" he said with a different voice than his usual one. Yuriko would easily recognize that voice as the dominating Ryo that had fucked her silly, but to Miku, it was a new side of him. She smiled alluringly and began unbuckling his pants. "Yes Master~ Let me service you plentily~"

When Miku pulled his pants and underwear down, Ryo's dick slapped her face. Her reaction was just as he expected. As soon as she had her prize in front of her, Miku began licking and smelling it. Pausing for a second she grabbed it with both hands and began masturbating him. She released a hot sigh when she felt just how hard he was.

"*sigh~* Master... you're so hard... let me help you~" Miku said, soon taking the dick as deep in her mouth as she could. Ryo could feel her gagging a bit, but she soon stopped. Still, he somehow wasn't happy with such a development. Miku should be more...

'Obedient'

"Miku, take it out" he said, clearly giving her an order. Miku was surprised at first but soon complied. She liked the way he had commanded her. She felt how in his control she was. "Now, stare at it, right in front of your face"

"Now, each time you do something out of place" Ryo said while staring at Miku's face, entranced by his cock. "You will be punished later on"

"Yes, Master" Miku answered while still staring at his cock. She so wanted it deep in her throat, roughly fucking her... but her Master had ordered her otherwise.

Ryo had her like that for a few moments. He could see the desire in her eyes and how she grew more aroused each second that passed. She flinched every now and then, probably holding her body back from moving. Ryo thought it was enough.

"Good girl" he said while smiling warmly. The stark contrast between his comanding tone and his face making Miku shiver. "Now open your mouth, you'll get your reward"

It didn't take even a second for Miku to open her mouth as wide as she could with her tongue out. Ryo immediately rammed his dick all the way down to her throat. Miku took it like a champ, slurping and vacuuming it while enjoying how roughly he fucked her mouth-pussy. Her mind was going haywire because of how much pleasure being used by Ryo brought her.

"Don't touch yourself" he said when he caught her hand sneakily moving towards her snatch. "If you behave I'll reward you"

Miku was dying to pleasure her pussy as he raped her throat, but the thought of the possible reward he would give her stopped her from acting on her desire. She was growing impatient, but Ryo, who had been building up his release, soon made her giddy.

"Since you've behaved... *grunt* drink it all!" he grunted as he plunged his cock into her throat until her lips were kissing his crotch. He groaned as he released all his cum down her throat, straight into her stomach.

When he finally stopped cumming, he took his cock out of her mouth and was surprised when he realized she had climaxed from that alone. She really was a submissive masochist.

"Show me your mouth..." he ordered the shaking girl. Miku obliged, opening her mouth wide and showing that she had swallowed everything, like the good girl she was.

"Good. Since you've behaved..." he said as he sat down in the bed. "I'll give you your rewards. Lay across my lap"

Miku stood up with her legs still a bit shaky from kneeling for so long, but she wanted her rewards so bad she didn't care. Laying across his lap, her clothes still donned, she anticipated what he would do.

*SMACK*

"Aaahn~ Master..." Minku moaned as soon as his hand fell heavily on her ass. Because Miku was also an enhanced human, he didn't have to worry much about hurting her skin. As such, he could spank her all he wanted.

*SMACK*

"Master, harder~" she moaned once again. She loved how her buttcheeks tingled with each slap they received. She could feel them heating up.

Ryo, deciding it was good enough, removed her shorts and left her only in her panties. He noticed she was wet and her love juiced tricled down the inside of her thighs. It was such an arousing sight.

*SMACK*

"Hyaaan~" Ryo relished in the sound of her moans. "Who are you, Miku?"

*SMACK*

Aaaahm~ Master's little bitch! I want Master to be rough with me!" she confessed her heart our, earning herself another spank in reward. "I want Master to use me for his own pleasure!"

*SMACK*

"Cumming~! I'm cumming from getting spanked!" Miku yelled in ecstasy. Ryo smirked when he saw that and propered her one last, harder than any before, spank. "Mashtaaa~! I'm cummiiiin'~!"

Ryo felt satisfied when he saw Miku spasming softly while laying across his lap. He played with her big ass, molding it in different shapes, making it jiggle and caressing it softly.

"You've behaved very well, Miku" he said while taking off her pantied and grabbing her by the waist. Ryo lifted her up and positioned her dripping pussy right on top of his cock, not penetrating her, but teasing her with the tip. "Now, you only need to do one thing for me to rewards you..."

Miku knew what he meant, and she didn't doubt even one second to it. Using both of her hands, she spread her pussy lips apart and spoke.

"Pleash Mashta~ drill ma pushy with your big, fat cock~" she said while throwing her head back, trying to look at his face. She couldn't because of their position, but she did hear Ryo humming. "Hmm... I expected more, but it is good enough"

After he said that, with Miku in a perfect Craddle, he allowed the tip of his dick enter her pussy. When it was in, he simply allowed her to fall down a bit, swallowing his cock entire.

"AAAAAHHHHN~" Miku moaned, not giving Ryo any signs of being in pain from losing her virginity. He would've leaned towards believing she wasn't one, if it weren't for the fact that he could clearly see the blood falling down from her pussy. "Ahm wan wi' Mashtaaa~ (I'm one with Master)"

Seeing how she didn't seem to be in pain, and knowing she preferred it rough, Ryo picked up the pace instantly, lifting her up and thrusting wildly from below. From time to time he hit her sweet spot, which made him grunt because of how Miku's pussy tightened around his cock.

"Aaahn~ Mashta's cock feelsh sho gud~!" Miku moaned wildly as he kept moving his hips, now allowing her to fall on his cock. The sudden action from gravity made it reach even deeper inside her pussy, something Miku allowed him to now. "Mah womb! Itsh toushin' mah womb!"

"*grunt* This masochistic pussy is so tight!" Ryo growled while thrusting even faster and harder. He was surprised by how easily Miku tightened her pussy around his rod. "Itsh because it wantsh Mashtaa sho much~!"

Ryo lifted his body from the bed and switched Miku's position to the famous Superman. The lack of hold and the strength of his thrusts was too much for the virgin to survive.

"Mashtaaa! Mashta! I'm cummiiiiin~!" Miku moaned as she squirted all over his legs and the floor of her room. Ryo was so excited seeing such a scene, that he couldn't hold back anymore.

Knowing full well that he couldn't risk a creampie, he chose the best possible option. Throwing himself on the bed, he put Miku in a full Nelson. His dick left her pussy, much to her displeasure, but she soon found other hole plugged.

"AAAAH! Mah ash! Mashta ish in mah ash~!" Miku said as she teared up. It hurt, but she felt so much more pleasure from that pain that her face contorted in a stupid ahegao. Ryo smirked as he felt how tight her ass was. It was totally different from a pussy.

"Are you feeling it, my little slut *grunt*! Are you getting off on having your ass raped?!" Ryo asked, realizing he was deeply enjoying "bullying" Miku during sex. The girl in question was moaning her heart out form the pleasure, answering in a barely understandable and very broken speech. "Yeeeesssssh! Miku'sh ge'in' ooov! (Miku's getting off)"

Ryo thrust harder once he felt more comfortable with the tightness of her ass. It had been a bit frightening at first, but now it was just perfect. He quickly felt the climax he had been building up for so long about to release.

"Take it in your ass! I'm pumping your bowels full of my cum! UGH!" Ryo grunted as he finally came, shooting loads of cum up Miku's ass. The girl in question was shaking on top of his cock, squirting in the bedsheets and unable to form any speech. "Mashtaaaaaaaa~!"

When Ryo finally released all his cum, he took his cock out of her, marveling at how his cum flowed out from her butthole.

"You behaved greatly, Miku" Ryo said while he patted the hair of the girl who, apparently, had lost consciousness. "You really are my good girl"

He tucked her in with a clean blanket, tucking her hair behind her ear while smiling warmly. Feeling his caress, Miku smiled even in her sleep. "Good night, Miku"

Ryo decided to sleep beside her for the night, getting under the blanket, he hugged her softly against his body. Soon, they were both asleep, with the only sound present in the room being their peaceful breathing.

Phew! I hope the R-18 chapters don't all look the same. I try my best to make each girls "fetishes" unique and different.
