Chapter 1

"Ah... Wait, you're already filming? Hey, Shin, you watching? We're about to have sex, just like you wanted, with your senpai here."

In a love hotel room.

I wave my hand towards the camera mounted on the tripod.

"Ugh, you're such a hopeless pervert... Wanting to watch your best friend have sex with another guy... Oh, and I'll probably end up enjoying it, so please, just forget about that part, okay?"

That's right.

I'm about to have sex with a guy I don't even like.

All for... my best friend's sake.

(Ugh, how did I end up in this mess...)

It all started last week.

---

"Hey, Asahi... I'm begging you, this is a once-in-a-lifetime request. Let me watch you get 'stolen'...!"

"Have you got maggots in your brain?"

A splendid right straight sent him flying.

The guy I'd just punched dropped to his knees with a thud and crumpled to the floor.

My name is Mikuriya Asahi. I'm a second-year student at Jotai University.

And the guy I just laid out is Okuchi Shin. My classmate. More like my childhood friend.

We've been stuck with each other since elementary school.

Our relationship is complicated and hard to explain... but anyway, let me tell you about myself.

My reflection in the nearest window is unmistakably that of a young female college student.

But until just a little while ago, I was a guy.

Has it even been a year yet?

Acquired Chromosomal something-or-other... In short, I came down with what's called "TS Disease."

I suddenly felt sick, was bleeding profusely from my backside, and rushed to the hospital where I was admitted immediately.

Luckily, I was able to return to high school after about two months, but it was a real pain hitting right before exam season.

Even though I've finally gotten somewhat used to it, it was pure panic, honestly.

The guys in class suddenly started looking at me differently, and the girls started treating me like a toy.

With all the procedures and everything else, I was already swamped, and then this world-turning-upside-down commotion happened, leaving me on the verge of a nervous breakdown, thinking "There's no way I can study for exams like this!"

But, during all that, it was Shin here who took care of everything for me, both at school and at home.

Even though he must have been really struggling inside, with his childhood buddy suddenly turning into a girl, he became a buffer against everyone else and even helped me study for my exams.

Thanks to him, I managed to get into the same university, and I'm honestly grateful.

Now we're sharing an apartment, living together while we get through campus life.

Huh? You ask if it's okay for a guy and a girl to live in the same room?

...Well, when a young guy and a girl—at least physically—live together, that kind of thing happens sometimes, sure.

Let me be clear, it's not like that was the plan from the start, okay?

I just felt like I owed Shin a lot for everything he'd done for me since this happened, and I was... well, curious.

So, we tried it once, just to see. It hurt like hell.

But ever since, our apartment has always had a bulk pack of condoms stocked.

Now, it's become... well, a form of nightly entertainment.

On the surface, we're still best friends, even if my gender changed! We let people think that, and when troublesome pick-up attempts happen, we use the boyfriend/girlfriend excuse to get out of it.

But if you ask if we actually see each other as the opposite sex now, it's pretty ambiguous.

That part hasn't changed since we were kids, and we both find it easier to keep it that way.

Maybe 'best friends who also have sex' is the most accurate description of my relationship with Shin.

So. That brings us back to the beginning.

I dragged the sprawled-out Shin all the way to the cafeteria.

I ordered some coffee and placed it in front of Shin, who was still dazed.

I had to get to the bottom of what he meant by that ridiculous statement earlier.

---

The incident where I asked my best friend to let me watch her get stolen, and got knocked out by a right straight for my trouble.

My name is Okuchi Shin.

And the person looking displeased in front of me is my childhood friend, best friend, roommate, and friends-with-benefits, Mikuriya Asahi.

Sorry for the suddenness, but I absolutely love netorare stuff.

Of course, the thought of a trusted lover falling for another man and abandoning me is heartbreaking. It makes me feel so miserable, like my heart is being torn apart.

But, it excites me just as much.

Even I think it's a troublesome fetish.

My relationship with Asahi is... a little complicated.

To begin with, 'she' was a 'he' until a few months ago.

But he contracted Acquired Sudden Chromosomal Conversion Syndrome, commonly known as TS Disease, a hard-to-treat illness.

It's a rare disease in this country with very few cases, and it still has a high mortality rate, but he miraculously recovered.

Even if he did turn into a beautiful girl.

Her bright, chestnut-brown hair hangs over her shoulders, tied back carelessly. She's wearing an unflattering hoodie on top.

Denim jeans below.

Plain, square-frame glasses.

You could call it the style of a unmotivated female college student, or you could just as easily see it as the drab look of an unpopular male student.

But her body line, those translucent emerald eyes, long eyelashes.

Her small but well-shaped breasts, her long, slender legs, and her well-proportioned figure.

And her hair, which should be unkempt, shines with healthy cuticles.

In fact, if she didn't dress so frumpily, she'd be a beauty that everyone in school would stare at.

This style serves, in a way, as camouflage.

After all, when 'he' came back last year, he thoughtlessly wore the girls' uniform and caused a huge commotion.

That's how impactful it was.

The rapidly changing environment around Asahi, due to her appearance, became a pressure that almost crushed her.

After consulting with Asahi's parents, I isolated Asahi and we studied for the entrance exams together.

Asahi's grades weren't that bad to begin with, so despite everyone's (and my) worries, she passed and got into this university.

Partly at the request of Asahi's parents, I ended up living in the same room with Asahi.

I initially refused, saying, "Well, Asahi's a girl now...", but Asahi's parents insisted, saying "If that's the case, then just take 'responsibility' for it," and I was overruled.

Responsibility... Can I handle it? I guess I have to.

A young man like me living with Asahi, who is (at least in appearance) a beautiful girl.

It was Asahi who initiated it.

As for me, feeling a vague sense of guilt, I wasn't really keen on the idea,

but once we crossed that line, we both kept sinking deeper and deeper into it.

If your first sexual experience is with such a beautiful girl, what man could hold back? No, none.

And so, our days were a bit decadent but fulfilling. Yet, within this peaceful daily life, my bad habit, my love for netorare, kept swelling up.

What if... Asahi was taken by another man.

Just thinking about it made my crotch swell to the point I couldn't hide it.

I see Asahi more as a childhood friend, a best friend, and I'm confident that I'm number one to her.

That's exactly why I wonder what would happen if her number one was surpassed by some random guy during sex——

Ah, I know. I'm the worst.

So, if Asahi strongly refused, then this conversation was over. I'd forget everything and we'd go back to how we were.

That's what I thought.

So, just on the off chance——I voiced this proposal to be cuckolded.

---

"So? Are my ears broken, or did I just hear 'sleep with another guy'?"

"Nah, your ears are fine."

"Then the problem is your fetish."

"Yep, that's about it," my pervert best friend laughs with a sheepish grin. What kind of wiring does this guy have?

How did he even come up with this idea?

"Look, of course I'm not trying to force you. If you don't want to, you can just say no."

Yeah, right, like anyone would say okay to that.

First of all, I'm not Shin's girlfriend or anything.

I'm not Shin's property to begin with, so the whole 'take' or 'be taken' thing doesn't even apply.

But——but then again, if you think about it, this is a 'new play request from a friends-with-benefits.'

A new play to break the monotony.

But with another guy? Hmm, honestly, I don't get it. If I were in his shoes, would I want to see my partner with someone else... Well.

I don't feel disgusted by the idea, but I'm not interested either.

Honestly, even as a new play, it doesn't sound very appealing.

But, I do owe Shin big time...

I can't just flat-out refuse him like that...

"Do you... really want to see it that badly? Me and... well, someone else?"

"Huh? Oh... yeah. I want to see it."

Seeing me show signs of considering it, Shin looked a little flustered, as if he hadn't expected it.

How rude. I'm not such an ingrate that I'd coldly refuse a request from my benefactor.

"Just once, though."

Once I said it out loud, I did get nervous after all.

That day, we hashed out the specific conditions for this netorare play and ended up returning to our apartment.

---

Just once.

Asahi strongly emphasized that it was just once.

But... she accepted. Sex with a guy other than me.

I was the one who proposed it.

This is what I wanted. But... I don't know. I feel unsettled.

Maybe, somewhere deep down, I had assumed Asahi would absolutely refuse.

Even though I'm not her boyfriend or anything.

And despite laying down various conditions, Asahi went along with my proposal to have sex with another guy, saying "Oh, alright then," and I couldn't hide my excitement about the situation.

Asahi laid out five conditions.

Proper contraception must be used.

If Asahi refuses at any point, it stops immediately.

No sexual acts that Asahi refuses to do.

No copying or giving the evidence video to anyone else; I keep the original.

And we don't tell anyone about this.

With the outer moats filled like that, I proceeded with preparations for 'that day.'

I already had a guy in mind.

"Hello? Go-san? It's Shin. Yes, Okuchi's son."

'Ah, Shin-kun. Long time no see. I heard you got into Jotai University. My old man always says thanks.'

"Likewise. Sorry for the sudden, rude request, but... well, I'd like you to sleep with my friend-with-benefits."

'What's that all about? lol, that's quite the thing to say out of the blue. lol'

"Well... let's just say it's my fetish. That kind of thing turns me on."

'Okuchi's second son has some pretty warped tastes too, huh? lol Ah, whatever, send me a pic of the girl. I'll decide after seeing it.'

"Understood. I'll send it right away. Okay then."

I hung up and sent Asahi's photo.

The other party is our university senpai, a fourth-year student named Ohira Go.

His father is the president of a fairly well-known company, and he's the successor.

Through my father's business connections, I've had the chance to talk to him a few times.

There were a few reasons I chose him.

One is... he's famous at university for being a womanizer.

He's tall, reasonably handsome, good at sports and academics, so he's popular.

On top of that, being the heir to a famous company, it's almost a given he'd have no shortage of women.

As for him, he goes through the women who throw themselves at him one after another, and the male classmates who hope to get some scraps often hang around him like a entourage.

"Anyway, once I join the company, I'll be set up with some young lady from somewhere and won't have any right to refuse. I'm just having fun until then. lol"

That's what he boasted, and it's probably not entirely wrong.

And another reason.

He's——very flashy. The so-called 'party people' type.

Asahi was originally quiet and inconspicuous in class... in other words, what you'd call an 'introvert,' and to be frank, she was never good with flashy, loud guys like him.

(So it's fine...)

What exactly is fine about it?

Maybe Asahi will dislike it and call the whole thing off right there.

Is that... what I'm hoping for?

I don't know. I was still——feeling unsettled.

Beep!

A notification sound from my smartphone signaled an incoming message.

'She's top-tier. Of course it's okay. More like, let me do her!'

It was a message from Go-san.

---

That was the story from last week.
And so now, I'm in a hotel with the flashy guy Shin brought along as the other participant.

We've both taken showers, and Shin set up the tripod and video camera.

He pressed record, leading to my line from earlier.

But, this guy...

He seems to be our university senpai, but he's really a smooth-talking, womanizing type.

His skin is tanned, probably from a tanning salon, and he has neatly dyed short blond hair.

He's pretty tall too... maybe around 190cm.

"Hey, it's Asahi-chan, right? That Shin guy is something else, huh? lol Handing over a cute girl like you."

"That's a matter between me and Shin. You just need to have some fun with me for one night, okay, Senpai?"

"Of course♪ Oh, and don't worry, I'll make sure to make Asahi-chan feel good too, not just me Lol."

"Either is fine with me..."

A party person. Undoubtedly, an outgoing, sociable party person.

The person I had to deal with was, unexpectedly, one of my least favorite types.

Shin... I might just end up resenting you for making me sleep with someone like this.

I'll make you treat me to a damn expensive steak later.

"But hey—I thought this when Shin showed me your picture too, but you're even cuter in person Lol."

"I'm not particularly happy about that."

"Now, now. No need to be so prickly Lol."

"This is just how I normally am."

Well, my mood isn't exactly great.

Shin did tell me we could stop if I felt really uncomfortable, but it's still within my tolerance for now.

I take off the towel wrapped around my body and toss it away.

I expose my naked body, not even wearing underwear, to this senpai-playboy guy.

"Whew~♪ And your figure is perfect too Lol. This is what they call a perk, huh Lol."

Senpai looks over my body with a lecherous gaze, as if licking me with his eyes.

So far, I feel nothing but disgust.

Seriously, do guys really stare at women's bodies like they're licking them? It's been a while since I felt this. Shin isn't really like that—I mean, he gets excited when he's holding me, but normally he treats me just like he did when I was a guy, and he always hurriedly helped me escape from guys who looked at me with those kinds of eyes, so facing this kind of gaze again after so long made me feel a little broken.

"Well then, time for my grand reveal too♪"

When Senpai takes off his tight boxer briefs, his huge dick springs out with a throb!

It's... It's huge...!

It was a massive cock, easily twice the size of mine from before or Shin's that I usually see.

Ugh... Is this... going inside me? Inside my vagina?

To be honest, it was bigger than I had imagined.

"Haha Lol, no need to stare at it so eagerly, I'll let you have a thorough taste of it Lol."

"...! I wasn't staring eagerly..."

"Yes, you were? You still are. Even if you look away, your gaze is totally fixed on it Lol."

Dammit...!

I was shocked by its sheer size, but being told I looked 'eager' made me look down in embarrassment.

It's not like I have a hobby of staring intently at dicks.

It's just... I couldn't help but think a little about what it would be like when that entered inside my vagina...

"Come on, just watching must be boring, right? Come over here."

Saying that, Senpai sat cross-legged on the bed and patted his lap.

I silently sat down with my back to him, between his legs.

This positioned me facing the camera on the tripod, with Senpai behind me.

His arms reached around from under my armpits, embracing my body, and his hands softly began groping my chest.

Senpai's rock-hard dick was pressed against my unprotected butt.

Even as he kneaded my breasts, my awareness kept getting drawn to the heated flesh rod against me.

"Hey, hey, you gotta focus over here too, or else... whoa!"

"Nngh!? ...kuh ♡"

Squeeze! Senpai pinched and pulled my nipple.

A sudden jolt of stimulation ran through my entire body, making me jolt with a Twitch!

As he proceeded to twist and knead both my nipples with his hands, a sweet sigh escaped me before I could stop it.

"Fuu... ♡ Nn... ♡"

While his large hands enveloped my breasts, squeezing and kneading them, his fingertips continued to play with my nipples.

A tingling pleasure spread from my nipples, combined with the heat of his cock against my butt and back, making my body gradually grow damp with sweat.

"Asahi-chan, does it feel good?"

"Not... really ♡ It doesn't feel... good... ♡"

"But you're showing how you feel good to Shin-kun, right? Come on, tell the camera what's being done to you right now?"

Damn it... Getting carried away...!

I tried my best to maintain my composure, but the more I tried to understand and explain my current situation, the more conscious I became of the stimulation on my nipples, making me feel Senpai's persistent caresses even more acutely.

Anyway, I just had to say something without thinking...

"Um... right now, Senpai is groping my breasts from behind. With his fingertips, he's... nn ♡ teasing my nipples... making them all hard... ♡ and every time he does, my body... nnk ♡ j-jerks... ♡"

"What about down below?"

"Be-Below? What do you mean...?"

Below? What is he suddenly talking about...?

"Your pussy ♡ How's your pussy feeling right now?"

"How...? Nngh ♡ Um, my pussy right now... is getting a little wet... nnn ♡"

When I moved my thighs, I could hear a squelch ♡ from the friction in my crotch.

My cheeks heated up with involuntary shame.

Getting wet from a man's caresses I don't even like isn't a great feeling.

This is just my body reacting on its own... that's all it is...

"Then let's work the field a little more Lol."

"Ha...? Huh? Fweh...!?"

Senpai wrapped his left arm around my waist, lifted my body slightly off the bed, and with his other hand—I don't know when he got it—switched on an electric massager.

He slid the device, which emitted a low Vrrrm, underneath my crotch.

When Senpai loosened the arm holding me, the vibrating massager got sandwiched between the bed and my pussy.

Meaning... the massager was pressed firmly against my crotch, its vibrations hitting my pussy directly.

"Nngh...! Aahhhhh...!! ♡"

An intense pleasure, like an electric current, raced from my slightly wet pussy throughout my entire body.

My vision sparkled for a moment, and I went limp involuntarily.

"Haha Lol, you came already just from the massager?"

"I... didn't... ♡"

I lied without thinking.

But Senpai pressed on relentlessly with his words.

"Really?"

"I d-didn't come...!"

"But your butt clenched tight?"

"I-I was just a little surprised..."

"You jerked and went limp with a Twitch! though?"

"Uu..."

"No need to hide it Lol. Shin would be happier if you properly showed him you're feeling good, right?"

That's right... that's true.

Shin is going to see this... ♡

Thinking that made me even more embarrassed, but at the same time, I felt I had to convey it properly.

Otherwise, what was the point of me being fondled by this playboy guy?

"I... came. I came from that just now. The massager made my pussy go bzzzt bzzzt and I came a little."

"Good girl Lol. Well then, let's make you feel even better Lol."

"Hah? Ngguh! ♡ Nnnnngguuuu... ♡"

Senpai leaned over me from behind, putting his weight on my body.

This pushed my body deeper into the bed, pressing the trapped massager even more firmly against my pussy.

Senpai's hands continued tirelessly kneading my breasts, and as his tongue, peeking over my shoulder, licked slurp slurp at the sensitive parts of my neck, the pleasure welling up from three different points echoed within my body, and I easily reached climax again.

"Nngh ♡ Kuh ♡ I'm saying... I'm coming... ♡ ♡ ♡"

Even as a pleasure that turned my mind white raced through me, Senpai didn't stop assaulting my entire body.

The massager, indifferent to my state, continued tormenting my pussy as long as the battery held out.

My body was filled with the endless echoes of pleasure's screams emanating from everywhere, erasing what little shame and reason I had left.

"Ohh ♡ Ohh ♡ Oohh...! ♡ ♡ ♡"

It's not like I'm trying to moan cutely just because I'm a girl now; a vulgar sob, one I wouldn't have let out even when I was a guy, escaped my lips as my body jerked Twitch, twitch! twice.

Slump! All the strength drained from my body.

I had been sitting on the edge of the bed and almost toppled forward towards the camera, but Senpai hurriedly caught and held my body.

"Whoa... Man, you came pretty hard, huh Lol Lol Lol"

I had even lost the energy to get angry at the vulgarly chuckling Senpai, and simply lay limply in his arms, savoring the lingering echoes of my climax.

"...With the prep work this thorough, it should be about time, right?"

————Prep work? What is he talking about?

Senpai laid me down on the bed, then leaned over me, bringing his face close to my lips.

Sensing instinctively that Senpai was trying to kiss me, I quickly blocked by putting my hand between our faces.

"A... A kiss, no kissing...!"

"Why? Don't kill the mood Lol."

"Kissing is... I haven't even... with Shin..."

That's right. I have sex with Shin, but I haven't allowed kissing.

For some reason, that alone felt like losing the last vestige of dignity from my time as a man, and I hated it.

Shin never brought it up and never said anything about me not trying to kiss him, so we've ended up never locking lips until now.

Therefore, I couldn't do that with Senpai.

Hearing that I don't even kiss Shin, Senpai looked a little surprised.

"Huh? ...You're a weird couple Lol."

He seemed to give up on kissing after saying that.

"But hey, in that case, what about my preparations?"

He says that and holds his thick meat spear, his cock, right in front of my face.

Even seeing it up close, it's still huge...

"What do you mean, 'do what'... wh-what should I do?"

"Put it on. The rubber. Or do you want to do it raw?"

Put the damn condom on yourself... Shin says he always puts it on himself...

It's things like this that I can't stand.

Sigh, do I really have to have sex with this guy? I probably do, since we've come this far...

"No good... raw is a no-go... NG..."

Somehow dragging my lethargic body, still languid with lingering pleasure, I take out a condom from the bedside drawer.

An XL should be fine, right? I tear the wrapper and take out the rubber.

I pinch the tip, place it over the grinning senpai's meat pole, and roll it down.

"It's still a bit tight for me, even with an XL! Lol"

Senpai grins at me as I put the condom on him. Shut up, like I care.

I smoothly roll it on, and it does seem a little tight, sure.

Feeling utterly drained, like I'd just finished a chore, I fell back onto the bed, landing on my back.

"Alrighty then! Lol My side's all good to go, so let's see how Asahi-chan is doing... Lol"

Saying that, Senpai casually slips his fingers into my crotch.

There was no need to check; my pussy was so soaked it was dripping down my thighs, so without any real resistance, it accepted Senpai's fingers.

"Nngh... Hahh ♡ C'mon... you don't need to check..."

"Now, now Lol, just being thorough, okay?"

Senpai's two fingers stir around inside my vagina.

He moves his fingers, gathering up my juices, and seeming satisfied, pulls them out from my crotch.

"Uha Lol, it's soaking wet! Lol"

Senpai laughs mockingly at me again, then spreads my knees apart with both hands, wedging his own body between them.

Now in a perfect position for insertion, Senpai grabs the base of his own meat spear with his right hand, presses the swollen, bulging tip against my secret slit, and begins rubbing it against my folds, making a squishy sound.

From that position, he uses his hips to press the tip against my vaginal entrance, then grabs my hips with both hands and continues moving his hips back and forth, sliding against me.

What a jerk. If you're gonna put it in, just get on with it already...

Sluuuuurp! Thump!

"Nnnyeeeeeeeeeesh!? Nnooohhh♡ Ooooooohhhh!! ♡♡♡"

I... so su-suddeeeeen! ♡

He thrusts in all at once while I'm off guard, and I come again.

The burning hot meat spear parts my vaginal flesh in one swift motion.

An intense penetration that feels like it's filling me up completely.

Overwhelmed by the violent pressure of Senpai's cock, my body arches back.

"Com... coming, so su-suddeeeen... ♡"

"Ahaha Lol, a successful ambush~ Lol But it's not all the way in yet, you know?"

"Huh...?"

Wait, my insides are already packed full, though?

All of it? You mean there's even more to take...?

Thump!

"Nnghaaah!?"

Senpai drives his hips forward strongly, one final thrust.

My already stretched-wide vaginal flesh has no way to resist.

The deepest part of me, which I thought was a dead end, is forced open, and my hidden cervix is mercilessly rammed.

From the shock, my mind goes blank for a second.

It's like being electrocuted with pleasure; there's no way I can fight against this.

———— A sex like this... I've never known it.

But the sex with Senpai has only just begun.

As Senpai slowly pulls his hips back, my vaginal flesh rubs against him so intensely it feels like my insides might be dragged out along his swollen head.

Then, the next instant, the meat spear plunges back in deep, to the very hilt.

Senpai continues thrusting with a slow, deliberate stroke, as if teaching its shape to my pussy.

Squelch♡ Glorp♡ Squish♡ Splurch♡ Squish-squelch♡

"Nnoohhh♡ Ohhoohh♡ Nnnaahh♡ Oooohhh♡ Fhoooohhh♡"

There's no room for composure.

I'm being made to come with every thrust.

My cervix is knocked tap, tap, and each time my consciousness easily fades away.

My vaginal flesh, instead of resisting the rudely invading foreign object, fawns over it, and each time it's caressed by that monstrous head, a gasp of delight is forced from my throat.

Gush♡ Sploosh♡ Squelch♡ Nnnglorp♡ Thump♡ Glug♡ Squelch♡

"Oooohhh♡ Nnnuuuhh♡ Aaahhh♡ Nnnoohhh♡ Oohho♡ Nnffuuuhh♡ Aaahhh♡"

"Haha Lol, Asahi-chan's pussy is totally fawning all over me! Lol"

"I'm... not f-fawning over anything♡ Nnaah♡ ...Aaahhh♡♡♡"

"It's tight as hell and you're dripping juices everywhere, saying that doesn't have any credibility Lol"

"Shut up♡ Just rub your cock and hurry up and come♡"

"The deepest part is a bit tight... maybe Shin's didn't reach all the way here?"

"Shin's♡ Don't say his♡ naaame... I'm coming♡♡♡"

Because Senpai mentioned Shin, his face inadvertently flashes in my mind.

When that happens, I suddenly feel intensely miserable about my own appearance—being made to pant so disgracefully, unable to hold back with a different man.

But the relentless piston thrusts of that wicked cock overwhelm those thoughts, tormenting me.

Shame and pleasure, misery and bliss, all get jumbled up, and somehow, I just stop understanding anything.

"Heya! Gonna pick up the pace! Learn my cock with that pussy of yours!"

Thrust! Slam! Squelch! Squish-squelch! Plunge! Slam! Squish-thump!

"Aaahhh♡ Haah♡ Agaaah♡ Ohooooh♡ Hoooh♡ Oaaahhh♡ Onnnh♡ Nnhoooon♡"

The violent, intense piston thrusts leave no doubt that he was holding back before.

I couldn't even handle the slow pace; there's no way I can endure this intensified assault.

Even as I desperately try to suppress my voice, my hips are held firmly in place, leaving my defenseless pussy with no escape as Senpai's wicked cock slams into it over and over, each time making me see white and moan helplessly.

"Here I come! Come from getting your womb pounded by my cumshot through the rubber!"

Slam! Thump! Squelch! Squish-thump! Slam! Thump! Squish-thump!

"Nnnguh♡ I'm coming♡ If you torment me like that, I'll come again♡ Don't pound my womb♡ I'm seriously coming♡"

With a final Thump! as Senpai drives his cock even deeper, the swollen member twitches and begins to spasm.

Throb! Throb! Throb-throb! Throb! Throbb! Throb! Throb-throb!

"Ahh♡ Ahh♡ Coming♡ Coming again♡ Coming from my womb being pounded by your cum through the rubber♡ Aaahhh♡♡♡"

In sync with the sensation of the twitching, pulsing cock moving inside my pussy, my own cervix quivers and twitches, clinging to the tip of the condom.

I arch my body like a bow, experiencing the climax with my entire being as I fall over the edge.

My rationality is long gone; even through the rubber, I clearly feel Senpai's ejaculation, and as I savor it, I achieve what must be the umpteenth orgasm of the day.

With a squish-squelch, Senpai pulls out his cock and lays his still-hard meat rod on my stomach, the condom tip now visibly swollen and filled with sperm.

The heavily inflated condom held enough to convince me that, without it, he would have surely gotten me pregnant.

Senpai removes the condom with his right hand, deftly ties it off, and tosses it toward my face.

The sensation of the dirty, used water-balloon condom hitting my cheek finally brings my consciousness back into clear focus.

"Please don't do such disgusting things..."

"Now, now Lol. C'mon, give the report to the camera, like, 'We're finished'♪"

Saying that as he helps my body sit up, Senpai whispers into my ear.

("...................." say it Lol. Shin'll probably jerk off to that, you know? Lol)

("Huh? You really want me to say something like that?")

("Just trust me and try saying it Lol")

"Sigh... um, Shin? Senpai's cock was amazing♡ It bullied me mercilessly in places your cock could never reach, and I ended up coming over and over♡ I'm sorry, Shin? I've been turned into a weak bitch who just keeps coming♡"

Honestly, I felt like my face was on fire, but I managed to say it with a smile.

Even though I was just repeating the words Senpai told me to say, it felt like I had truly been turned into a weak bitch—a secret I'd keep from both Shin and Senpai.

That kind of thing ————— there's no way I could say it.

As soon as I finish my line, Senpai presses the stop button on the camera, ending the recording.

It's finally over...

The relief finally washes over me that this nightmare of a task is finished.

———— But I was naive. I hadn't known just how strong Senpai's sex drive was.

"Alrighty then. Now that the filming's over, I've got a proposal. How about one more round, raw, please?"

"What are you saying, Senpai? I said no to no contraception, right?"

"Yep. We'll use contraception. I actually brought some morning-after pills with me."

I'm shocked by the sudden suggestion.

What do you mean, 'actually'? You probably brought them planning for this from the start.

"The filming is done, so there's no reason I have to do it with you anymore."

"But Asahi-chan, you were holding back a lot earlier because of Shin, right? Wouldn't that leave you unsatisfied?"

"————!?"

My face grows hot, as if my inner thoughts have been seen right through.

Of course it does. No matter how monstrous Senpai's dick is, no matter how it makes me want to cry out, I… I just can't moan loudly right in front of Shin.

But I hadn't even considered the idea that it was unsatisfying until Senpai said it.

To call it unsatisfying… after sex that incredible…

"Yeah? See how amazing a raw dick is? You ever done it with Shin?"

"Shin wouldn't ask for something so unreasonable."

"Then you should try it at least once, lol. I made sure to film the part for Shin, right? And I listened to your boyfriend's request. Don't you think I deserve a little reward for my trouble?"

"Uhgh…"

Now that he mentions it, from Senpai's perspective, he was asked to have sex with someone who isn't even his lover. In that sense, I suppose he has a point.

As if seeing my slight hesitation, Senpai presses on.

"Just say you accidentally forgot to record it or the memory was full, lol. It's not like you have to show Shin everything. Doing it once or doing it twice, it's all the same, right?"

He says this, holding out a pill to me.

Thoughtfully, he even provides a bottle of tea.

If I accept this… it means I'm giving him the OK.

Even with a condom, birth control isn't 100% effective. So… so…

————And so, I accepted the morning-after pill and the proposal for a second round, raw, from Senpai.

---

I return alone today to the apartment where we live together.

To satisfy my foolish desire, Asahi is being held by another man, that Senpai, tonight.

My heart feels like it's going to break with anxiety, yet at the same time, I'm so excited I feel like I could climax right now.

Thinking of Asahi being held and moaning for Senpai somewhere, I ended up pleasuring myself alone multiple times that day.

"Nnngooohhoohh♡"

Senpai's raw dick enters me from behind, doggy-style. I can clearly feel the rough, textured shape of his cock, something you can't feel through a condom. And the heat, so intense it's like magma, threatening to scorch the walls of my pussy.

Th-this is… more dangerous than I imagined♡

"You don't have to hold back, you know? Be louder!"

"It's amaaazing♡ This♡ This♡ I've never known this♡ I've never known a dick like this♡"

Thrust! Squelch! Squish! Squelch! Plap! Plap-plap! Squish-squish-squelch!

"Nnhaaahh!♡ Aaahh♡ It's too much♡ I'm gonna♡ I'm gonna cum from this♡ If I get fucked by a dick like this, I'm gonna lose consciousness again♡♡♡"

"Lol, it's so easy to tell when you're about to cum, Asahi-chan, your butt gets all tight."

"Shut up shut up shut up♡ Just because I… I came don't get so cocky♡"

Even as I get worked up over him laughing at my pathetic climaxing state, I keep cumming every time he thrusts, so it's hopeless. Just as I talk back, Squelch! Another deep thrust makes me cum again.

"See, it got tight again, lol. How many times is this you've cum, Asahi-chan?"

"I dooon't knooow♡ Ever since we started♡ Every time he goes Plap-plap!♡ inside me♡ I've been cuuuming♡ I don't know the count anymoooreeeee♡♡♡"

"That's hilarious, lol! Your pussy is totally begging for it, isn't it? Lol!"

He laughs as he rams Thump! deep inside me, making me cum. I lose the strength in my arms and fall face-first onto the bed. I end up in a degrading position, ass raised towards Senpai, taking his dick in a posture that seems to beg for his cock.

As my body quivers and shakes, unable to resist the lingering climax, suddenly Slam! He pushes his dick into me, leaning his weight on me from above. My legs, already weak and trembling from continuous orgasms, can't hold out and are pressed flat against the bed.

"Oooohhh!?♡♡♡"

"Hey, don't you dare cum without permission! If you're gonna cum, at least say 'I'm cumming'!"

"I'm… I'm cumm… I'm cuuumiiing♡♡♡"

With that deep, weight-bearing thrust, I easily cum again. Pinning my flailing legs down, Senpai plunges his dick deep, deep inside me over and over, pounding my innermost depths.

"I'm cumming♡ I'm cumming♡ I'm cumming♡ Every time you thrust, I cum♡ Cumming, cumming, cumming again♡"

I climax each time. I scream "Cumming, cumming♡" as if roaring. I couldn't think anymore. I was reduced to nothing but a sexual plaything, a pathetic flesh toy, screaming "Cumming, cumming" to Senpai's thrusts.

"I'm gonna shoot my load…! I'm gonna unload the thickest one I've got today…!"

"Oooohhh♡ Ohhoooohhh♡"

I can't even form words anymore. Cumming♡ Cumming♡ If he cums inside me like this, I'll go insane with pleasure, my nerves will burn out from this incredible climax♡

Pulse! Spurt! Spurt! Spurt-spurt-spurt! Squirgle!

"Aaahhh♡ I'm cumming♡ I'm cuuummiiiiiiiiiiiiing!!♡♡♡"

Hot semen pours into my womb from the tip of his twitching cock. My womb, my very womanhood, trembles with joy as it guzzles down the potent sperm of a strong male, the kind that would surely get me pregnant without the pill. Bathed in the intense wave of euphoria spreading from my core throughout my entire body, I experience and succumb to the biggest climax of the day.

"Hey… I've got a proposal. If you're up for it, Asahi-chan… how about we do this again sometime?"

As I lie there, tongue hanging out sloppily, savoring the climax, Senpai's lips draw near to mine. A kiss I haven't even allowed Shin. But I accept Senpai's kissing proposal————

---

"Senpai's dick was so amazing♡ He teased me deep in places your dick can't reach, and I ended up cumming over and over♡ Sorry, Shin? I was turned into a total cum-crazy, weak little slut♡"

Asahi was so erotic, smiling and saying that. The sight of Asahi moaning, writhing, and reveling in pleasure with Senpai like I'd never seen before… was incredible.

When Asahi came back the next day, it was the usual Asahi. After that, we had sex many times while watching the video. Maybe because it's embarrassing to see herself, she gets all pouty and refuses to look, but she still has sex with me as usual, almost every night.

————But lately, just a little. Just a tiny bit, the days when Asahi doesn't come home have increased.

Asahi joined a new club at university. The club where that Senpai is.

'Club activities are keeping me busy.'
That's the reason Asahi gives for not coming home more often.

Probably, meeting with Senpai.
Meeting with Senpai and————having sex.

But the sight of Asahi's slightly flushed face the next day after not coming home… that fulfilled "slutty" look… it makes me unbearably excited.

Ah, I hate myself like this.
Being miserably ranked as inferior as a male, having my most important male friend since childhood turned into a slut.
Getting excited by this base desire for "her."

Asahi is my best friend. My childhood friend, my most important best friend.
We have sex, but we're definitely not lovers.
So even if Asahi has sex with Senpai, it's not cheating.

And yet, today again————I'm holding my cuckolded best friend, getting excited.
