Chapter 50: Seibu Rein Anus Interrogation-Arc

That day, classes finished at noon, and so I returned home to the apartment together with Rein, who had become my slave.

Sunou had not come. Kokoros fever had also begun to fall, and it seems that she thought I would come home during the morning.

All of them are like this, but even if one thinks that its useless at the time, there are times when it does see some use.

This has gone past the point of pointless and become boorish.

Well, I guess so.

I sometimes gathered playing equipment in this apartment.

This time it was the type of chain that could be hung from the ceiling. Of course, I cant drill a hole into the apartment, so its something that had become only for show.

Rein was suspended by those chains, restrained in the centre of the room with both arms raised.

Really, what are you thinking with this?

While following my orders as a slave and taking up that appearance, she was glaring at me, looking down as though she was utterly dumbfounded.

While thanking Rein who made such an expression, I smiled.

Well, its probably not something very productive.

Isnt that obvious!? Doing this sort of thingeven these clothes dont just belong to me, you know!

While fidgeting uncomfortably, Rein surveyed the clothes she was currently wearing.

What Rein was wearing right now was the white military uniform that was drawn on that culture festival poster. I had borrowed it after poking around the executive committee.

What, Ive got permission.

Thats not what I meant! You, Ill be using this in the culture festival!

Heeh.

I hummed shamelessly.

It appears that it has been determined that Rein will be wearing this during the culture festival. Well, since theyve gone to the extent of making posters, theres nothing strange about it.

The attire for her first anal violation shouldering the burden of acting as a poster girl for the culture festival was fascinating.

Well then, how are you feeling now?

You, youre asking even though you know, arent you?

Although the background was uncertain, the current Rein was wearing a military uniform.

Because she was restrained in it, although I feel bad for her, I thought that the atmosphere was enjoyable.

While tasting what it feels like to be an inquisitor, so to speak, I shrugged my shoulders.

Is it not better for you to properly respond? You should know your place.

What, should I say that I can smell the nice scent of flowers?

Youre stubborn, huh? I dont really care either way, though.

Even while Rein was a slave, she never submitted to me.

Even though she answers my orders, that is strictly because my position is higher than hers.

I slowly turned around to Reins behind.

Rein tried to direct only her neck this way, but when I went around her back, she couldnt see me anymore.

Perhaps because I was conscious of the fact that the military uniforms trousers were for womens use, her waist line had become quite visible. From her white pants, the outlines of her shapely butt could be clearly seen.

Well then, shall we borrow the great slaves butt for a little bit?

dont keep talking nonsense. Why dont you just touch it whenever you want?

Haha, you really dont get it, do you?

First, I placed my index finger against the back of Reins knees, raising it upwards as though I were quickly stroking it.

Surprised, Rein jumped a little in fright as the suggestion of being touched by me took effect.

Dipping my fingers in the sensation of her squishy butt, I started tracing it with the tips of my other fingers.

After gently stroking it several times, I hit Reins butt with great momentum.

High!?

Rein raised a slight moan. But of course. The item used for the purposes of expanding the hole was still crammed inside this butt.

Even though I was just petting her, I could see that strong reaction. It appears that, in this posture, she was fairly aware of the foreign matter entered inside her.

You, you really better remember this

Rein was probably persuading herself that this couldnt be helped because she was a slave.

At any rate, even if I released her from being a slave, she wouldnt be able to attack me.

Removing Reins belt, I pulled down her trousers. Without resistance, the trousers fell to Reins feet with a *plop*.

Youre wearing some pretty cute underwear, huh.

Shut up! Just hurry up and do it already!

Its not something to be that upset about. Im complimenting you.

Rein unhappily grit her teeth.

Even like that, since her anus would react with just a press of my finger, it was cute.

Lets pull down her panties and have her let me see her adorable butt and vagina.

It appears that the suggestion to go into heat was properly taking effect. Love juice flowed from her vagina, to the point where it followed down her thighs.

However, this time wont be the vagina.

Ighhh

Rein tightly shut her eyes, making an effort to not be conscious of it. Of course, if she did that sort of thing, then shell just end up becoming more aware of it.

Using my fingers, I slightly pushed in and pulled out the vibrator that was caught in Reins anus.

If youre gonna do it, then do it

Rein was irritated as she received the stimulation to her anus. Due to that influence, her pigeon-toed feet trembled.

With a *drag*, I slowly removed the vibrator.

Uuughnghhh!!

Reins face flushed, bringing her chin forwards as though straining herself. While her body received a slight feeling of release, she gathered strength into her stomach.

To her, it was humiliating as it was like she had been watched excreting.

To me, its precisely because Rein receives this disgrace as humiliation that its fun.

Mm, nghhaah

I took the vibrator from Reins butt. The still expanded hole of her anus twitched without closing.

I inserted my finger into that anus, trying to stir it up around and around.

Hyah!?

Hey now, endure it, endure it. Dont tell me the great and proud Mistress Rein cant even do that?

Whatproud?

I opened the lotion that I had prepared in advance, and painted my fingers with it.

Next, I inserted both my index and middle fingers, and teased her anus as though gouging it out.

Highigh!!

To Rein, this was the first stimulation. Strongly closing her lips and eyelids, she tried to endure it.

I purposefully made an obscene *squelching* noise as I painted the lotion, making sounds so that Rein, whose eyes were closed, could hear it.

The buttocks are a very sensitive part of the humans. It could be said that the nerves were concentrated there.

If pleasure is linked with her genitals there, then its possible to play with it even more than the vagina.

If youre going to put it in, thenhurry up and do it already

Rein should enjoy yourself too.

Theres no way that Id..enjoy this!!

Rein still seemed to have picked up from somewhere the strong impression that sexual intercourse was something vulgar.

Even up until now, even though she received pleasure from being ejaculated inside of her vagina, I knew that the sentiment to disapprove of it surged inside of her.

Thats why, this time, I was thinking that Id get her to admit it.

Answer honestly.

Yeah, its the worst feel!

Before Rein could finish speaking, I placed my penis against her.

Seeing her body twitching just from that was adorable. While stroking her butt with the tip of my penis, I vigorously pushed against it.

The worst, huh?

Its pointlessreally, whats so fun about this? -ahkaahreally, its stupid.

The head of the penis entered inside of Reins anus. Reins butt that was just developed today is really tight.

Rein frowned at the sensation of the foreign body entering her. Even so, her anus puckered up and stimulated my penis as though sucking it.

Its a natural phenomenon

I didnt say anything, though.

I further inserted my penis even deeper. With a *squeak*, the solid which originally shouldnt have entered pried open her butt.

Perhaps because it was painful, Reins mouth was left agape as she repeatedly breathed in and out.

Now, Im gonna move.

You should, just, do what you want! Im just letting you do it afteraaahhh!!

When I pulled out my penis, a sensation akin to rubbing skin was transmitted through my lower body.

Rein stretched her back straight, as though she had been shocked, and the chains that were attached to her arms rattled loudly.

The figure of her shutting her eyes and clenching her teeth was so terribly sadistic and wonderful.

Does it hurt?

Isnt that obviouscant you tell!!?

How are you feeling? Answer honestly.

Rein did not immediately reply that it was the worst. After breathing several times, her mouth, which was chewing her lips, opened.

it tingles.

Haha, I see.

Rein did not admit to the pleasure, but she could not say that it was unpleasant either. That was probably vexing to her.

Thats why, as the only resistance available to her, she was only able to say that.

Kyahwhat!?

I thought that Id give you a bit of variety, see.

While grabbing Reins butt, I stirred up her vagina with my free fingers. Over the insides of her vagina, I was able to touch my penis that was inside of her intestines.

I tinkered with Reins intestines from the inside and out.

Kyaah! Aagh! Nnghahh!

Hey now, whats wrong?

Hyah, mgh!!

I brought my own lips towards Reins ear and blew against it.

I was satisfied upon hearing a pitiful voice that was unlike Rein.

In the mean time, I also continued to piston with my penis. Sometimes I twisted my waist and scooped out her anus, satiating myself with Reins shrieks. With the shape of my penis, I did the utmost to gouge out her anus, demanding pleasure.

Her anus, like a tool being messed around with by an unrestrained child, could only stay passive, unable to resist.

Restraining her was the right choice. Because of it, I could feel as though I were rampaging as I pleased.

Aahhigigh

That burden was directed towards Reins own body. Desperately suppressing the pain and pleasure, she was weakened like a fish that had been raised out of water.

It should be fine soon.

After this, Ill end things once I obtain the words of acceptance of the pleasure.

Hey now, how is it?

ahgah

Rein looked back with unfocused pupils.

While feeling a slight sense of accomplishment from that expression, I prompted her for the finishing words.

So that I wouldnt be able to miss it even if she spoke in a small voice, I brought my face towards her mouth.

Now then, wont you tell me how you feeel right nomgh!?

For just an instant, sharpness returned to Reins eyes.

In the next instant, no sooner then when I wondered about what she was doing, she turned to my lips and thrust out her chin, kissing me.

Mgh!!

Nngh!!

Neither of us could talk to each other.

So that I couldnt tear myself away from her, Rein strongly sucked my lips and didnt let me go.

And, as though saying that she was doing her hardest to resist, Rein pulled back her waist and gathered strength into her butt.

Towards those chain of actions that seemed as though they were squeezing me out, my penis, that was on the verge of ejaculation, accidentally fired off.

Mmgh, nnnnnnnnnnnnnnnnghh!!

Rein screamed inside my mouth. At the same time, the insides of her vagina squirted and began to convulse.

My heat-filled semen smashed against the insides of Reins intestines.

For a few seconds, the two of us stayed in that position, as though we were immersed in the lingering memory of the act.

The first to move was Rein.

puhahhaah, haah

After separating from my lips, Rein folded her knees and squatted. Both her arms were connected to the chains, so it almost looked like she was being hung.

While looking down at such a Rein, I touched my lips that still had the sensation of being sucked left on it.

there, its alreadyover, right? Hurrytake this off

While flashing a fearless grin, Rein looked up at me triumphantly.

If I were to once again ask here how it it felt, then she would probably reply honestly.

Thats right, good job.

However, doing that is just boring, and my pride wouldnt allow it.

I learned that Reins more of a sore loser than expected.

At the last moment, that girl displayed the utmost resistance that was possible for her. I sealed my mouth, as though saying things werent going as I intended.

I should express my respects here.

Just wait a sec.

While removing the chains that were attached to her, I viewed Reins figure who was catching her breath.

If she was brave, then she wouldnt be ashamed of the proud military uniform, huh.

There, this should be fine, right?

Geezdo you make Kokoro-san do all these sorts of things? How pointless.

Perhaps because she had been obtained a small victory, Reins mood became a little better. Even though shes a slave, shes quite the impudent fellow.

Think a little bit about your partner.

Ill consider it in the future.

After being released from the chains, Rein placed her fingers against her sweaty forehead and wiped it. And naturally those fingers were placed against her lips.

what?

Nothing.

After that, Rein immediately looked at me and glared as though reproaching me.

I simply shrugged my shoulders and laughed.

Lets have her yield to me at another opportunity.
