"You'll be mine from today." He whispered into her ear before nibbling her ear. He rubbed his cock on her bare pussy, lubing it up.
"Kazu-kun~ I don't think~ This is a good idea~" She was unbearably aroused but still tried to persuade Kazuya to not take her virginity.
"Don't worry, just leave everything to me. I'll take care of everything." He kissed her earlobe before he started pushing his cock into her tight pussy.
"Ahh!" She screamed because she felt a lot of pain, strangely she felt that the pain was pleasurable.
With the presence of the seal, Kazuya could sense her emotions and could sense the real masochist that was 'yandere' Mami spilling over to the 'cutesy' Mami, as he liked to call them both.
He used the seal to amplify her arousal to make sure that the pain works more to please her.
He kept slowly pushing in his cock and when he finally met a slight obstruction, Kazuya turned Mami's head toward him and kissed her.
Then he pushed his cock into the depths of her pussy, ripping through her hymen.
"Mhhhmm~" She moaned loudly into his mouth, although she felt a hefty amount of pain, most of which strangely made her feel pleasure.
Then Kazuya started pistoning her slowly, enjoying the tightness of her perfect pussy.
He let go of the kiss and got up behind her, sitting on his knees. With him he pulled Mami's ass up, making her bury her face in the bed.
"Such a perfect ass…"
"Kazu-Kunn~" Her whine is slightly muffled as she has an idea about what he's going to do.
He lightly penetrates his thumb into her asshole, all the while fucking her with gusto.
He pushed it in completely since he knew that she'd be slightly used to the feeling.
Then with his other hand, he spanked her.
*Smack*
At that moment, both of her holes tightened up and his cock felt even better inside her pussy.
'…Is there a way to use the seal to awaken her other personality?' Kazuya tried to do that but there was no change.
Mami's moans and actions were still the same.
'I guess it was too farfetched for the seal, huh? Guess I gotta go the hard route, though it's a pain… Maybe after the first round.'
He used the seal to keep track of and keep her arousal amplified.
"Cumming~ Kazu-kun~" Soon, she ended up cumming. Kazuya had no plans to stop here so he kept going.
In her amplified arousal state, Mami ended up cumming seven times before Kazuya filled her up.
Even Kazuya thought that it was a bit too much. The poor girl seemed to have melted into the bed by the time he came inside her.
Sadly for Mami's tired body though, there was another personality that he had to take care of.
'She doesn't know about her other persona, so I should just go the same route as last time and use her jealousy. Though I need to find a better way to get the 'other' out though…'
"Mami, how about I call Chizuru, and we have a threesome?" Even Kazuya cringed at his words and shitty proposal for a threesome. Thankfully he wouldn't have to continue since it seemed to have worked.
Mami was giving him a dead-eyed hate-filled look.
"That's the girl I wanted to meet." Kazuya got on top of her and held her hands above her head.
"Mmm," She struggled without saying anything.
'Can she not speak? Or does she not want to speak? Interesting…'
"I'm not planning to leave you like that. Since I decided to take care of Mami, that means both the Mamis. Can't let you stay unsatisfied now, can I my yandere?" His expression was anything but healthy. He seemed to be just as obsessed with the yandere as the yandere was with him.
She still didn't speak anything.
"Though, we do need something to call you out. Even I don't like capitalizing on your jealousy like that. So I'm going to make a trigger word— Switch. If I say that you need to come out, got it?"
Seemingly in defiance, she turned her head to the side.
'Fiesty, eh? It's fine, I got all kinds of toys here just for her. I'm going to leave her a mess after this.'
"Don't want to listen? It's fine, I have my ways."
When Kazuya brought out handcuffs from the bedside, he checked her lust.
[Lust: 35(95)/100]
Checking her lust value, Kazuya realized that she was barely keeping herself sane, 'Talk about conviction…'
Kazuya turned her around and cuffed her hands behind her back.
*Click*
Next, he brought out a thick leather collar from the side drawer along with a leash.
Mami was already struggling, so Kazuya had to overpower her to collar her neck. He tied it tightly around her neck, making her have to take short breaths.
She still didn't say anything except for struggling.
Kazuya would think that he is raping her but if the state of her lust and arousal were anything to go by, she was much more into this than she made it seem.
With that, in an almost poetic way, Kazuya got up on his knees and started fucking her in the same position as he did the cutesy Mami, the only difference being the handcuffs and the collar.
"Ahh~" The moment he rammed his cock into her pussy, he realized that she would cum within the next few thrusts.
He held on to her waist and brought her up, his hand being her only support in this position since her hands were tied behind her back.
Although she wasn't saying anything, her moans were amazing, to say the least. The voice was the same as Mami, but the tone and the feel behind it were completely different.
Then he grabbed her leash and pulled it back, straining her neck and choking her.
He wrapped the leash around his hand and kept it taut. When he let go of her waist, all the support that was there was her leash and it choked her completely, making her unable to breathe at all.
Kazuya could feel her pussy tighten up immensely around his cock before she convulsed in her position.
"Ackkk~" She came violently and squirted her juices all over the bed, the choking was extremely effective.
"You'll come out when I say switch. Understood?" Kazuya said to her in a forceful seeming voice and the yandere seemed to cave and weakly nodded with a lustful expression as Kazuya kept pistoning inside her.
He let her leash loose since he didn't want to choke her into fainting, at least not before he came.
He might be a kinky fucker, but necrophilia wasn't his thing.
He fucked her much harder and rougher than the 'cutesy' Mami and made her cum almost 9 times before he finished inside her.
Most of her orgasms were accompanied by breathplay as Kazuya relished in the feeling of her tightened pussy while he choked her.
How she was still conscious was something even he didn't understand.
What he did understand was that the yandere was a thirsty bitch and wanted him to keep fucking her until she died.
When he was done, Mami completely fainted and fell limply on the bed.
Kazuya freed her hands, taking off the cuffs but he left the collar and leash there. He wanted Mami to feel slightly degraded and humiliated too.
Her other persona might be a hardcore masochist and he wanted those feelings to spill out to the 'cutesy' Mami too.
'Now to check the main function of this seal… It's called a chastity seal, right? Does it have the capability to prevent all penetration?'
Kazuya thought that, and the seal seemed to have burst into life, turning into a physical construct from just a tattoo.
It formed beautiful golden panties that matched the color of her hair. They were lined with a sort of red lining that gave them a regal look. The thing that sealed the deal was the keyhole that was placed right in the center of the panties, right above the area of her labia. It didn't seem to serve any purpose other than being decorative.
It seemed to be completely stuck on her skin, preventing anything from even attempting to touch her privates.
'Shit… this just got supernatural... I'm going to transition to some sort of fantasy element sooner or later, aren't I? Up until now, the system only provided semi-supernatural benefits, like knowledge and skills. But this thing is a real construct… Forget, it. I might as well enjoy my time with my girls. Guess, I got a real reason to work toward success…'
Kazuya had a multitude of thoughts when he was a real construct appearing from the system and knew that his life wasn't going to be as simple as he thought at first.
'I got all the more reason to work on the AI. I need to set up the server in a safe place…'
Kazuya forgot all about the chastity panties that Mami was stuck in and started thinking about unnecessary things for a while.
It took him around 15 minutes before he realized that it wasn't the time to be thinking about this stuff.
'God, that turns me on.' Looking at Mami, wearing such a regal-looking pair of panties knowing that she didn't have any control over them and would have to ask him to even go to the bathroom, turned him on to no end.
'Now… What should I do about this? I could tell her that this is a highly advanced technology and convince her but it seems a little farfetched… I could just not use them at all, but… That seems such a waste of this ability of the seal.'
Kazuya thought for a while and decided that he might as well start making her feel that he has control over her life far more than she would like.
'Let's get you out of that failed politician's house, shall we?' The background research that Kazuya had done on Mami told him that her father was a political figure, one who was valued by a Fujiwara higher-up.
He used to be extremely influential and had deep pockets and even deeper connections. Now though, his situation was down in the gutters and he was struggling to keep himself afloat.
He didn't exactly know how her childhood went, but he could tell from her usual behavior that she was someone who was extremely sheltered and kept under control by her father ever since she was a child.
'I'm pretty sure that he controlled every single aspect of her life like some sort of tyrant.'
'With her father's current situation, I wouldn't put it ahead of him to use Mami as some sort of political marriage pawn. That's not something that I'm going to see happen. She's mine…'
Kazuya might seem like some sort of meek lover when he was with his girls but he was in no way a pushover. He'd pamper the people he cared about to no end but when it came to people taking his things, he would get extremely possessive.
If Chizuru hadn't agreed to his relationship with Mami and tried to leave him, he would've turned everything over and kept her with him, even if it was forceful.
'In two weeks, I'll give her a job offer to be my secretary. She's plenty qualified, so it's not like I'll be unfairly giving her the job, anyway.'
Gimme those power stones!
