First, Say Hello to My Cock
Ding-dong. Ding-dong.
At the sound of the doorbell ringing from the entryway, I opened the door with an excited heart, as if a package had just arrived.
"You're here?"
"..."
Yun Seolah stood at the door, making no effort to hide her uncomfortable expression.
She held a shopping bag in her hand.
I couldn't help but wonder what kind of swimsuit was inside.
"Well? Did you pick out a good one?"
When I let her in and asked, her voice sounded completely drained.
"...Yes."
"Really? Let's have a look. Go into the room and change."
"...You'll let me go before Yena gets back, right?"
"If you behave?"
"...No backing out."
"Oh, by the way. You know you don't wear underwear under a swimsuit, right?"
"..."
Instead of answering, she shot me a fierce glare before walking into the room.
While waiting for her to change, I let my imagination run wild.
What kind of swimsuit would it be?
In terms of pure lewdness, a micro-bikini or a slingshot swimsuit would be the best, but they probably don't sell those at a department store.
Then, even if it wasn't a micro, maybe a regular bikini or a monokini?
Even if it was just a normal swimsuit, seeing it on a body like hers in person would be a feast for the eyes.
Click.
Oh, she must be done changing.
As the door slowly opened, Yun Seolah's figure revealed itself.
And what wrapped around her body was...
"Huh?"
It was neither a bikini nor a monokini, but a competitive swimsuit you'd only see at the Olympics.
"I'm pretty sure I told you to buy the lewdest swimsuit possible?"
"It—it is a lewd swimsuit. It clings to the body and shows off all the lines..."
Don't people usually think of high exposure when they think of a "lewd swimsuit"?
The one she was wearing now covered both her chest and her stomach completely.
Vrrr!
What was that? A message?
Ah. Reading Sora's message made it all make sense.
So she deliberately chose the least revealing one, huh?
Because she could just insist that she thought this was the lewdest one?
It was her own little way of resisting, trying to keep me from enjoying myself too much.
Or maybe she thought that if I was less aroused by a boring swimsuit, the intensity of our play would decrease as well.
"You don't like it? Oh dear... I chose it because I thought this was the lewdest one..."
Yun Seolah put on a stellar performance, pretending she had done her absolute best.
Unfortunately for her, there were two things she didn't realize.
First, every single one of her moves was being reported to me.
And second...
"No, it's actually great!"
Her body was so magnificent that it could turn even a competitive swimsuit into something incredibly erotic.
"...What? You like it?"
"Yeah! It's fucking hot! You picked perfectly."
"T-That can't be."
Judging by her quiet murmur, she seemed quite shocked that her petty rebellion had failed.
But in truth, she looked so incredibly sexy right now that I couldn't even think of any other swimsuit.
Her chest was stretched taut as it struggled to contain her absurdly large breasts, and her waistline perfectly accentuated her beautiful feminine curves.
The slight bulge where the fabric covered her pussy was a sight to behold, and the bare skin of her hips on either side was equally satisfying.
"You've got good taste. You secretly know a lot about men, don't you?"
"...!"
Sensing my gaze, Yun Seolah quickly covered her crotch with both hands.
Her face flushed with frustration at the fact that she had unintentionally pleased me.
That glaring look of hers, combined with a body that was the definition of pure lust, was a true delicacy.

"It seems our tastes align pretty well. Right?"
"...I'm not happy about it at all, so stop talking nonsense."
"Want me to tell you something good? This swimsuit can become even lewder."
"What?"
Actually, there was a trick to these competitive swimsuits that could boost their sex appeal even further.
Well, it wasn't really a secret, as many people knew about it.
"Stay still."
"No! D-Don't touch me!"
When she tried to block my approaching hands, I put some weight into my voice.
"Stay still. Are you disobeying me?"
"What are you trying to do...!"
"Put both hands above your head. Quick."
"..."
Her hands slowly rose in obedience to the command.
With her upper body now completely defenseless, my hands approached.
"What in the...!"
I gathered the fabric covering her breasts, pulled it to the center, and tucked it right into her cleavage.
"Don't put your hands down."
"Ugh..."
A soft gasp escaped Yun Seolah's lips.
She was now in a vulgar state, wearing a competitive swimsuit with only her breasts completely exposed, but my command forced her to keep her arms raised.
The swimsuit's purpose of covering her body was rendered completely meaningless. Instead, it created an overwhelming sight that only emphasized her bursting breasts.
By the way, she was sweating buckets again.
She really had a sweaty constitution.

"Wow... your tits are seriously so fucking hot. Your armpits are clean, too."
"Shut up... don't look..."
"I'm complimenting you, why the attitude?"
I flicked her nipple with the tip of my finger.
"Hieek!"
Jiggle.
I had barely touched her, but her entire body flinched, and her water-balloon-like breasts jiggled in tandem.
"You seem even more sensitive than yesterday. Did you masturbate too hard?"
"I told you I didn't do anything like that!"
Even if she denied it, I knew she had masturbated while playing with her nipples yesterday.
I had cross-checked it with Sora before going to bed, so there was no doubt.
"Anyway, I should enjoy myself today too. Only you got to have fun yesterday. Ah, your arms must be getting tired, right? You can put them down."
Yun Seolah's hands slid down from behind her head, quickly covering the pink nipples that had been stealing my gaze.
"Now, come over here and kneel."
Yun Seolah lowered her body in front of me as ordered.
My crotch was naturally positioned right in front of her face, and her brow immediately furrowed in disgust.
"You have a rough idea of what we're doing next, right?"
"..."
"Relax your face. I told you before, I'm not trying to torture you."
"Then why are you doing this?"
"Since you hate lewd things so much, I wanted to teach you why you shouldn't hate something this good. So we can enjoy it together."
"Is that really the reason...?"
I gave a light nod to her incredulous question.
"You called me a beast and a pervert just for watching a porn video, and told me not to get near your daughter. Meanwhile, you squirted all over the living room floor just from having your clit touched."
"T-That was...!"
"And yet you tell me you're different from someone like me, that you're not a beast. From my perspective, isn't that ridiculous? That's why I'm making you realize it. You're no different from me, and once you let go and enjoy it, there's nothing better than lewd things."
To be honest, it was true that I accepted Sora's proposal out of anger at being treated like a potential criminal and the desire to possess a beautiful woman.
However, the reason I just told Yun Seolah was also genuine.
The hypocrisy of someone who cannot be free from sexual desire themselves, yet criticizes and tries to control the sexual desires of others.
I was truly sick and tired of that hypocrisy, which censors so frequently display.
"...I don't understand. Even if I admit that I'm no different from you, what do you gain from that? What's the point?"
"There's no grand meaning. We just keep doing things like this and enjoying each other."
"...What?"
Hearing my words, Yun Seolah still looked utterly bewildered.
"That's why I told you from the start to just think of it as having a fuck buddy and enjoy it. I get to relieve my stress, and you get a change of pace when raising Yena alone gets tough. Isn't that great?"
And on top of that, it advances the mission of my AI friend from the future.
"...If that really is your goal, then stop. I will never admit that I'm like you. I'll say it as many times as it takes. I am different from a beast like you."
"We'll see. I don't think it'll take as long as you think. Well, anyway."
Since we had talked enough, I wanted to get straight to the point, so I reached for my waistband.
"Today, it's my turn to be served."
"Hmph. Do whatever you want."
For some reason, Yun Seolah, who had been confused just a moment ago, snorted at my words.
"Why do you suddenly seem so confident?"
"Because now I know exactly what your goal is. I'll hold out until the end and make you give up."
"Really? Well, give it your best shot. First, say hello to my cock."
"It's bound to be pathetic anyway. You watch porn at home and cowardly blackmail women because you lack confidence as a man, don't you? The tool of a man like that is bound to be miserable without even looking... Huh?"
"What's wrong?"
She stopped mid-sentence, her eyes widening.
Reflected in her dilated pupils was my cock, which had finally been unleashed.
"W-What on earth..."
Actually, my boy down there is a bit—no, a lot—on the giant side.
It was 22 centimeters long, and so thick that even I couldn't wrap a single hand fully around it.
On top of that, looking down at Yun Seolah's breasts had put it in peak condition.
It was born magnificent, but until now, it had only been played with by my own hand, let alone a woman's. Finally, it was time to put it to good use.
