Chapter 87

Change of Heart Level 1 has the effect of preparing the vagina for easy penis insertion, but the pleasure enhancement conveyed to the woman isn't very strong.

It's worlds apart from Change of Heart Level 5, where just one penis insertion sends her straight to paradise.

However, it's not like Change of Heart Level 1 has a negative pleasure modifier.

If you think about it, the pleasure itself is actually stronger compared to regular sex.

If you add Hideo's technique, honed from fucking countless vaginas, to that enhancement, it was a simple matter for Hideo to give vaginas sufficient pleasure even at Change of Heart Level 1, if he so desired.

Just like in this case.

"Ah, haaaah! Ugh... Oh! W-wait a minute! G-gently, please! I-I'm begging you! T-this is too intense!♥ A-it hurts!♥"

She's screaming that it hurts, but the lustful tone in her voice was obvious.

Even if it hurt, Hideo didn't care at all. After all, the important thing was Hideo himself feeling good. It's possible that the bitch's vagina might hurt a little, but that doesn't mean Hideo has to stop jacking off because of it.

Hideo pulled on Haku's arms, shoving his penis even deeper inside.

Perhaps because Haku was small, her vagina was also short; simply inserting his penis was enough to reach her cervix.

Forcibly pulling her arms and pushing his penis in that state, Haku's uterus suffered almost crushing pressure,

"Kkueeeeet!"

She made a sound like a squashed frog, and eventually opened her cervix, letting Hideo's penis inside.

Normally, this kind of thing shouldn't be possible from an ergonomic standpoint, but before the supernatural power of the Common Sense Alteration Gacha, even things that are generally considered impossible are entirely possible.

It's truly the power to force the impossible.

"Ooh, that's fucking amazing. I don't think I've ever inserted this far before? Is this like a hidden route you can only use with a small onahole?"

Unlike the gleefully laughing Hideo, Haku was in agony.

Her brain short-circuited from a sensation she couldn't properly gauge as pleasure or pain, and she couldn't think straight anymore.

Only the realistic fear that her uterus ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠might be destroyed if things continued this way remained.

"N-noooo! T-take it out! I-it's breaking! It's breaking!"

"Take it out? Like this?"

Unexpectedly, Hideo obediently pulled his penis out of Haku's uterus. But that was only for a moment.

"Eh, but it was a good discovery, so one more time."

"Agagagagak!! Aaaah!"

When Hideo shoved his penis into her uterus again, the cervix opened even more easily than before, welcoming Hideo's penis.

"Ooh~♥ The cervix is stimulating my glans, it feels so good? Is this like a double onahole~? Nice. Should I keep going with this!"

Hideo moved in a direction that completely ignored Haku's pain.

To Hideo, her uterus was now completely an onahole itself.

Not even a cum receptacle, just a device to generate pleasure.

"Ughhhh! Kkeoeot! Heunggghoooooot!!"

Every time Hideo's penis went in and out of Haku, Haku let out filthy, vulgar screams that were hard to imagine coming from her small frame.

Hideo found that pathetic sight very amusing.

"Hey, hey. Are you okay? Hakuuuu~? Your boyfriend is watching you through this camera right now, you know? Isn't he going to lose interest seeing his girlfriend in such a mess?"

"Hit!"

Only now did Haku begin to notice the existence of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the camera filming them.

From the moment Hideo pounded her uterus, her boyfriend's existence, which had been outside her consciousness, emerged as a new threat within Haku.

"D-don't watch... Yuuji, please, don't watch this..."

"Hey, don't talk nonsense. It's a video your girlfriend is sending as a birthday present, so of course you have to watch it to the end and give your impressions, right?"

Hideo said sarcastically, then asked Haku as if he had just remembered something.

"Ah, now that I think about it, what's your boyfriend-ssi's penis like? Doesn't it reach this far?"

"I-it doesn't! Yuuji doesn't do such, such horrible things!"

Haku wanted to emphasize how good her boyfriend was, but Hideo took it completely differently.

"Hmph~? Looks like Haku's boyfriend has a micro-penis. That's too bad. It's a waste not being able to effectively use a dedicated onahole like this. As a man, that's a bit pathetic, isn't it?"

"D-don't insult Yuuji!"

Haku confronted Hideo as firmly as she could.

She could accept being insulted herself, but she could never let an insult against the boyfriend she loved most in this world pass.

Haku had never felt any lack in her sex life with Yuuji.

Haku herself didn't know ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it, but Yuuji's equipment was below average. But even with that penis, there was no problem in giving Haku happiness.

Love isn't determined by sex alone, or by the penis alone. That was obvious to Haku and her boyfriend, a fact that didn't even need to be said.

Unfortunately for Haku and her boyfriend, Haku's attitude instead became a catalyst that ignited Hideo's desire for conquest, or perhaps his sadistic urges, very intensely.

"Hoo~? You're talking back, huh? I was just saying something to a fool who doesn't even know how to use his dedicated vagina properly. I guess I have no choice."

Hideo pulled on Haku's wrist, which he was holding, and changed their position.

Until now, they were side-lying missionary position from the camera's perspective, but now it was a sitting position facing the camera directly.

"Hey~? Have you been watching well so far? Boyfriend-ssi, I heard you've been wasting this high-quality onahole? You shouldn't do that~? That's the worst kind of waste for both the man and the woman~? A girlfriend is like a personal onahole that you can use anytime, right? You need to learn how to use it properly."

"....."

How could there be such a vulgar human being in the world?

Haku felt nothing but despair at the thought of her boyfriend watching this video.

She wasn't afraid that her boyfriend would misunderstand her after seeing this.

She only feared one thing: that her boyfriend would be hurt by the cruel treatment Haku was receiving after seeing this.

Yuuji would be sad to see her being treated so promiscuously. Haku believed that without a doubt.

"So, I'll give you a proper explanation of how ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to use an onahole from the front, so I hope you can use it effectively later, boyfriend-ssi."

Hideo said such nonsense, grabbed Haku's waist, and abruptly shoved his penis into Haku's vagina.

"Aguaaaaat?!?!!? Huk, kkeueooooot!!"

Haku, who had her cervix penetrated in an instant as before, let out a scream so filthy it was heartbreaking to hear, and tilted her head back.

Ignoring Haku, Hideo flaunted his and Haku's junction towards the camera.

"Alright~? See this, boyfriend-ssi? A woman's vagina is a tool to make a man's penis feel good, so you have to use it properly. Sticking your penis in so deep that it's not even visible is the correct way to use it. Got it? Caring about a woman's orgasm or feelings is unmanly, so stop it."

Hideo, preaching an arrogant machismo that wouldn't be recognized even in the pre-modern era, let alone the old generation.

He proved how sincere he was about that ideology through his actions.

"Alright, like this. Huh? Use the girl's body like it's an onahole."

Haku, held in Hideo's grasp, was lifted up and down as Hideo moved.

It was possible because Haku's frame was so light and Hideo was stronger than he looked...

Even considering that, it was a sex that seemed unbelievable at first glance.

As if Haku had truly become an onahole itself.

"Kkot! Ot! Ooooot!! Heugeeeeet!! Aaaah!"

"Haa~ feels good. Boyfriend-ssi, I'm a little jealous? Having such a high-quality onahole as your girlfriend. I ended up borrowing it unintentionally, but forgive me~? It's not like I'm doing it because I want to, it's because Haku begged me so much that I had no choice! Right?"

Haku couldn't say a word of explanation about that.

Every time Hideo's penis pierced her vagina, the words she was about to say all went back into her throat.

In the first place, it's ridiculous for an onahole to speak.

"Ah, by the way, it feels so good to have my glans sucked by this cervix? You have something good~ Haa, boyfriend-ssi~ I heard you haven't tried this yet, but you really have to try it once. There's another onahole inside the onahole? It's on a different level than a 1+1 event."

Hideo, reviewing Haku's vagina like an early adopter, said with a nonchalant smile.

"Oh, right. You said your penis doesn't reach this far? Haa, that's too bad. Not being able to use this good thing properly. Hmm~ Boyfriend-ssi, I've never met you, but maybe you and Haku have bad chemistry? Well, if you love each other, it can't be helped."

Hideo, who spouted such nonsense without a care, said this as if to reassure the boyfriend.

"Well, don't worry too much? I don't have any romantic feelings for this onahole. I'll give her back after I use her properly. I don't know if I'll give her back clean, though."

It is not known whether those words were comforting to the boyfriend.
