Pant...

Riko lies on the bed and breathing out deeply.

Her face is red and looks tense.

「You don't feel it?」

「Umm... I'm just embarrassed」

「Okay」

As she said this, Chihiro put his face and fingers close to Riko's hairless crotch.

He lightly placed his fingers on either side of the crotch and split it open.

They did not kiss or do anything else, even though they were giving a pleasure to each other. And because they had a rather serious conversation in the middle, the wetness is still insufficient.

That's why the inside of flesh can be seen clearly.

「If it's like this, Riko should be able to feel good」

...Even if it's not like Maria, who climaxes when her body is scribbled on.

But if it's an act of play, the shame will turn to excitement.

「Uuuh...」

Riko didn't protest too strongly, as if she couldn't deny it.

And so, he began to trace his finger around the entrance of her crotch and lightly stimulate her clitoris. Then, taking the slightest bit of wetness on his finger, he crawl inside her vagina.

「Mmmm」

Riko shuts her eyes and starts to let out a sweet voice.

...But it's going to take a while for her to get wet on her own.

So, Chihiro moved to caressing her clitoris with her tongue, and then started to cunnilingus.

Lick.. Lick..

He extended his tongue to tease the area around her pubic mound.

This area is sensitive enough because it was close to her genitals, and he could give Riko a gentle sexual sensation. Besides, this area is clean and does not taste of sweat since she has just taken a bath.

Next, the crotch. He moves his tongue tracing it up. At the same time, the saliva will gradually increase the slipperiness, and the tongue will be able to penetrate deeper.

Once that is done, he can enter and play with it as he wishes. He licks and tastes the flesh inside, and then he moves his tongue around.

Then, lick her pointy clitoris.

After that, mixing her love juices with the saliva, and slurping it up.

「Oh... Hya...」

Riko couldn't help but cover her face.

But this is where the shame play really begins.

The key is Maria, rather than Chihiro.

「Mmm... Fuu」

She is sitting beside Chihiro and the others, comforting herself. She lifted her breasts with both hands and squeezed them lightly.

The way her breasts swayed and her white fingers dug into her skin is extremely arousing.

And when she is in the mood, she moves on to the nipples instead of the whole breast.

She pinches them with her thumb and forefinger, and the nipples begin to grow erect. Then, while placing her palm on the breast, she starts to roll it with the tip of her index finger.

「Ah... Mmm!」

Maria pinched her nipple and shuddered.

And seeking a stronger stimulation, her right hand reached for her crotch while her left hand continued to play with her nipple. Like Riko, she split open her hairless mound with one hand and scratched around inside.

Squelch... Squelch...

It seems that the inside of her vagina is already quite wet.

So, she slides two fingers in and out, and after a few smooth thrusts, she reaches for her clitoris and pinches it, too.

「Mmmmm...!」

Maria's body shakes again, and she stops masturbating.

She turns her head to look at Chihiro and Riko with a ragged breath.

「Master, I'm ready」

「Good. Maria, straddle Riko's face」

「Yes」

Maria nodded obediently and carried out Chihiro's order.

She approaches Riko from the side and straddles her legs over Riko's.

「Riko...I'll do it」

「Y-Yeah」

After giving a small nod, Maria dropped her hips down on top of Riko.

And Riko is in a position where her mouth is buried in Maria's vagina. Although the folded legs are supporting the body, Maria is almost sitting on Riko's face.

Her nose is open, so she can breathe.

「Fuu... Mmm」

Riko can't seem to speak due to her mouth being blocked.

When Maria confirmed this, she turned to face Chihiro.

「Master, how is it?」

「Yes, thank you. I think it's good」

A threesome, with one of the girls in the middle.

This is what Chihiro ordered Maria and the others to do this time.

Chihiro had a couple of experiences with having him in the middle - being mounted and serviced by another girl, but this is a first.

Well, both of them had done 69 in lesbian play and had licked their partner's vagina before.

That said, there must be a different kind of embarrassment when one is completely seated.

「*pant... this is a little fun...」

Maria seems to like it a lot.

She seems to be enjoying it as a skinship between slaves, or as a shame play for herself.

「Then, Riko, lick Maria and make her cum」

「Mmm, mmm...」

She may have thought it was impossible.

But she must have realized she couldn't refuse. So, Riko opened her mouth and extended her tongue to Maria's secret place.

「Oh...Riko」

Maria let out a wistful cry.

As expected of two girls. Riko's cunnilingus seems to be accurate, and the dark-haired girl shivers in ecstasy.

It's a beautiful sight that makes him want to keep watching.

...But it's not shame play if he just watches in silence.

So, in order to remind himself, he pinched Riko's clit carelessly.

「――Ah!」

It worked.

The timing of the pinch caught Riko off guard as she is about to concentrate on caressing Maria, and she stopped her mouth movements and shook herself.

And Maria didn't miss it.

She said what she thinks she would have been excited to hear if she had been told like this, and while she was careful, she didn't show any mercy.

「Riko, your tongue is stopped」

「!」

By nature, humans are not very good at multitasking.

Especially when it comes to sexual intercourse, where thoughts tend to become simple due to pleasure.

That's why it's so effective.

Lick.. Lick..

Riko resumes her cunnilingus. After confirming this, Chihiro starts to work on Riko again.

「Aaah!」

When Riko's tongue stops moving in pleasure, Chihiro stops blaming her.

Chihiro repeats this over and over to give Riko an illusion.

When she blames Maria, she feels good too.

In other words, she is now blaming herself.

「Riko, you have to work hard or you won't be able to cum」

Without saying who, he whispered, and it seemed to do the trick.

Riko began to work Maria more aggressively than ever before.

「Oh, Riko, that's good」

Maria occasionally adjusted her body position to accept Riko's tongue. Chihiro also checks how Maria feels and adjusts the pressure to be as equal as possible.

Before long, Riko's crotch was flooding.

Slurp.. Slurp..

Squelch.. Squelch..

Riko breathes hard through her nose, and occasionally sucks in a mouthful of air as she works. Maria, on the other hand, gradually stops saying meaningful words and only lets out sporadic gasps and raspy breaths.

Now, the girls' pleasures must be synchronized to a large degree.

In a way it's masturbation, in a way it's lesbian play. But in fact, it's Chihiro who's torturing Riko, and it's Chihiro who's giving orders to Maria.

「Ah...Master...!」

「Maria, are you going to cum?」

「Yes, I'm about to cum... Please let me cum」

「Okay, then」

Riko hears their conversation and starts to move faster. To make herself cum.

The sound of water, breathing, and panting echoed in the soundproof room...

「I'm coming...I'm coming...I'm coming...!」

As soon as Chihiro heard Maria's declaration, she pinched Riko's clit harder than ever.

「Aaahhh――!」

The two girls' voices overlapped. Maria lifted her hips as she climaxed, and Riko seemed to be able to speak more freely.

With a gasp of air, Maria pulled away from Riko.

「Riko, did that feel good?」

「*pant* *pant*...?yes, it felt good」

Riko replied, sounding dreamy.

She seemed to be floating in a state of fever, simply because she was hot from Maria's body heat.

「I see. Then, can you do it again?」

「Huh?」

The girl's mouth dropped open.

Riko understood the meaning after a few seconds, and said to Chihiro while half raising her body.

「Wait, wait a minute. One more time?」

「Because I haven't cum yet」

Seeing this, Maria giggled and nodded as she spread her vagina with her fingers.

「That's right. ...Riko, Master is right.」

「No, you. Are you just saying what you want because you're in an easy position?」

「No? I envy you」

「Well... that's the kind of girl you are」

Sigh..

When Riko looked up again, her face had returned to that of a female slave.

「Okay, Master... please enjoy my cunt」

She said and lay back down.

「Good girl, Riko」

Maria straddled Riko's face again as she caught her breath.

「Maria, you'll have to remember that later」

「Yes, I'll look forward to it」

As soon as the girl's face is covered again, Chihiro inserted his penis.

He swung his hips, enjoying the feel of her wet pussy, and worked her mercilessly. Because of the pleasure of penetration, Riko continued to serve Maria desperately, though she stopped her tongue frequently.

There is a different kind of pleasure this time from the last time.

Since she is being fucked by the opposite sex while serving the same sex, the pleasures are not synchronized. Instead, the degree of multitasking will increase, and her consciousness will be distracted more intensely.

She will not be able to comprehend anything.

Only think about what feels good.

Perhaps her heart was touched, because Riko's tongue moved faster as the speed of penetration increased. Maria also moves her hips to get pleasure together with Chihiro and Riko, and rubs her clit against Riko's face.

And then...

「Oh, I'm cumming...」

「Mmmmmmm!」

Spurt! Spurttttt!

As Chihiro ejaculated, Maria and Riko climaxed again.

He waited for the semen to stop flowing and pulled out his penis. Maria also moved out of the way from above Riko's face, but she remained lying limp.

「Oh... this is pretty hard」

「I bet it is. Even if she's not suffocating, her breathing is restricted」

Maria replied, patting Riko's head in place of Chihiro, who was in a bad position.

Just now, it's just like choking sex and it feels good.

The more their bodies and minds are tortured in this way, the better they feel. He wants Riko and the others to experience the pleasure of slavery, the pleasure of masochism.

Chihiro wants them to be unable to leave him.

「Then it's Maria's turn to be held by Master」

「Fufu. ...Yes, I want to taste a lot of Master's cum in my pussy」

After a brief pause, Maria is now in the middle and Riko is straddling her.

As Maria herself said, the condition of her vagina was different from that of Riko's, but instead of being reluctant, Maria became more excited and gave cunnilingus to Riko.

Then, after Chihiro ejaculated twice, they took a break again. After that, Riko and Maria took turns to have sex with him in the normal cowgirl position.

As there was no clock in the bedroom, it is hard to tell, but it took quite a long time for the three of them to fall asleep exhausted.

When he woke up as usual, it was morning, and Riko was giving him a blowjob wearing nothing except a choker, with traces of semen on her body.

「Good morning, Chihiro. Did you sleep well?」

「Yes, good morning. Are you feeling sleepy, Riko?」

「I'm fine. Anyway, why don't you go take a shower with me after you're refreshed?」

It didn't take more than five minutes for ejaculate.

After that, he went to the bathroom with Riko and asked her to wash his body.

「Hey, Chihiro. We're still the same even if you join the student council, right?」

「...Of course. We won't change」

「Oh... I'm glad... then I'm relieved」

Riko smiled shyly.
