Once I was seated on the edge of the bed, Miki knelt before me, reached out, and began unfastening my belt with a clatter.
After loosening the belt, she unzipped my pants and pulled out my half-erect penis in an instant.
"Here it is, all mine now, isn't it?" Miki said with a delighted expression, stroking my shaft from base to tip.
I didn't bother to protest that it was still my penis; I simply let her do as she pleased.
As blood flowed in and my erection hardened, Miki pinched the glans between her fingers, moving them up and down as she peeled back the foreskin.
"So hard already... This cock is definitely the best..."
With practiced ease, she fully retracted the foreskin. Miki's expression turned dreamy as she gazed intently at the exposed glans.
"Everything's ready now. Just wait a moment, I'll put on a condom for you. Oh, and take off your pants."
With that, Miki stood up and started rummaging through the depths of a drawer in the wardrobe.
Following her instructions, I stripped off my pants, exposing my lower body.
But despite these physical movements, my mind was in utter turmoil.
A condom...
That meant... it was finally happening... we were really about to do it... have sex.
With Miki-chan... the friend my younger sister brought home... the beautiful girl who seemed so out of reach...
The moment this reality hit me, my pulse went haywire, and a strange sweat broke out on my skin.
A tremor started in my gut, spreading through my entire body and refusing to stop.
Just as my breathing grew even more labored, Miki returned with a rubber from her bag.
Crouching before my groin to face my penis, she looked up at me with a puzzled expression.
"Um, excuse me? Why is it going all soft?"
"Huh? Oh, uh, I-I'm just nervous..."
"Nervous?"
Miki's eyes widened in surprise before she let out a dramatic sigh.
My penis had lost all its strength and wilted limply.
"Now it's impossible to put the rubber on..."
"S-sorry..."
"Seriously, it gets rock-hard if you just leave it alone, but when it comes time to actually use it, it's completely useless..."
Miki lowered her head and glared at my penis with her signature scornful expression, hurling insults at it.
Poor thing. If it gets hard too quickly, it gets hit. If it doesn't get hard at all, it still gets hit.
"But I guess stuff like that really exists. How interesting. I wonder how to make it bigger..."
Miki's expression suddenly lit up with amusement, and she stood up again.
She put the rubber in her mouth with a naughty grin, gripped the edges of her skirt with both hands, and slowly raised her arms.
The hem of her skirt gradually rose, revealing her pure white panties until they were completely exposed.
"Want a peep show? Getting excited?"
...This is erotic. I never realized how erotic it would be for her to show herself like this.
And the rubber in her mouth adds an undeniable rawness to the scene.
But my cock remained flaccid.
Watching my reaction, Miki then started taking off her panties while still wearing her skirt.
She raised her leg, smoothly slipped them off, and once again gave me a fleeting glimpse of her skirt hiked up.
Even without prompting, the shadow beneath her skirt revealed her pussy, capturing my gaze.
"Look at this, your pussy... don't you want to fuck it?"
"I... I do, of course..."
"Then hurry up and make it hard!"
Even the sight of a no-pant skirt lift, something that should have guaranteed a full erection, left my cock unresponsive.
The more she urged me, the more flustered I became, my cock remaining utterly silent.
Why? Why won't it move? This was a first for me.
What if I end up impotent like this?
"Ugh, you're hopeless..."
Even Miki, usually so composed, released her grip on her skirt with a look of exasperation.
Giving up, as if out of options, she abandoned the teasing lift and slumped down beside me.
"Ugh... I was so looking forward to some ecchi time..."
"I-I'm so sorry..."
"Seriously, you're hopeless. You complete failure of a penis."
Oh no, Miki-chan is actually mad...
But given the circumstances, it's understandable.
Honestly, I wish she'd just curse me out until she's satisfied. Please scold this useless cock some more.
As I remained silent, head bowed, Miki leaned up and peered into my face.
"...Are you mad?"
"N-no, of course not. You're right, after all..."
I hastily shook my head, and Miki smiled faintly.
"Right? For a moment, I even thought you didn't want to do it with me."
"No, no, that's not..."
"Really? You want to fuck my pussy?"
"H-hai! Yes, I want to! I do!"
"Hehehe, that's more like it. That's what my boyfriend should say."
Miki lightly tapped my head, stood up, and finally threw her skirt aside.
I was transfixed by the sight of her crotch peeking out from beneath her blouse when Miki suddenly straddled my lap.
The softness of her buttocks pressed against my thighs. At the same time, Miki's eager face was right in front of mine.
"Aww, what a shame. If your cock were a little bigger, it might've fit inside."
As she spoke, Miki wrapped her arms around my neck and pushed me down onto the bed.
Surprised, I lay back, accepting the soft weight above me. Miki's face immediately drew near, her lips pressing firmly against mine.
A sweet fragrance filled my nostrils as her tongue swiftly invaded, sliding against my mucous membranes with a sticky wetness.
"Haa... ham... chu... nmuu..."
Her tongue moved with fierce tenderness, a deep kiss clearly fueled by passion, unlike our previous encounters.
Desperately, I wrapped my arms around Miki's back, returning her kiss.
The repeated kisses, filled with affection, made it undeniable that we had become lovers, whether I liked it or not.
Her tongue felt so good, so pleasantly warm...
The kiss lasted for a long time.
By then, my consciousness was completely consumed by the sensation of devouring Miki's mouth, leaving no room for extraneous thoughts.
Squelch, squelch, smacking sounds—the exchange of saliva and our rough breathing relentlessly stimulated my brain, awakening my pure reproductive instincts.
My flaccid penis, which had been so limp, had somehow regained its vigor.
"Mmm, mmm... Haa... Chu... Haa..."
Miki's lips, clinging to me, released hot breaths.
Straddling me, Miki subtly rocked her hips, grinding her crotch against my hardened penis.
Every time Miki moved, pressing my erect penis against her, a fierce pleasure surged through me.
The glans was slick with my pre-cum, the shaft coated in Miki's love juice, until my entire penis had become sticky with the mixture.
"Ngh, you're so big now!"
Finally pulling away, Miki grinned and firmly gripped my penis.
Miki toyed with the glans, now slick with pre-cum and love juice, as she sat up and looked down at me, still lying on my back on the bed.
"Alright then, this time for sure..."
Still holding my penis, Miki bent her knees and lifted her hips.
She positioned herself so that her crotch was directly above my erect penis.
"Huh? Wait a minute..."
"I don't want to have to deal with it wilting again, so I'm just going in."
"What?! No!"
"Going in" meant, of course, without a condom.
The rubber had been tossed aside somewhere without my noticing.
"As long as I don't come inside you, it should be fine. Today's a safe day, anyway."
Is that really safe...?
But Miki didn't give me a chance to think. She pressed the tip of my glans against her secret place.
"Alright, here I go? Make sure you watch carefully, okay? This is the first time a penis will enter a pussy."
With that, Miki slowly rolled up the hem of her blouse with one hand and began to lower herself onto me.
A wet squelch echoed as our mucous membranes slid together, and with surprisingly little resistance, my penis slowly sank deeper into Miki's body.
The sensation of entering her for the first time was, above all, warmth.
I couldn't find the words to describe anything else. My mind felt sluggish.
I stared blankly at the sight of my penis disappearing into her, as if it were happening to someone else.
Part of it was the lingering haze from our long, deep kiss, but even as I finally graduated from virginity, it all felt strangely unreal.
It was like being in one of those erotic dreams I sometimes had... as if I were dreaming right now.
But there was nothing we could do about it.
Just a few hours earlier, I never would have dreamed this would happen.
"Ugh, you're really... so much..."
About halfway in, Miki's hips paused, her expression contorting.
But the movement quickly resumed, and my penis silently sank deeper into her.
Finally, Miki's hips lowered completely, and my penis was fully engulfed by her pussy.
"Haaah... It seems like you're all... the way in now. By the way, this means I've lost my virginity."
"Huh?"
"Yeah, I'm used to putting various things inside myself, but this is the first time a real penis has been inside me. Strictly speaking, it was the thick, rubber-covered tool—the 'Bachi'—that actually took my virginity..."
"B-Bachi?"
"Um, I just couldn't resist the temptation to try it... When I went inside, blood came out, so I think the hymen broke. Just to be clear, I definitely didn't do it with my brother! I mean, it would be weird if we were actually siblings, so I hit the brakes..."
Watching Miki speak, a little embarrassed, filled me with both amusement and tenderness.
The mere thought of this seemingly serious girl doing such a thing made me want to burst into laughter.
"Congratulations, bro, on graduating from virginity. Heh, but your first time being pinned down by a girl and going raw? That's pretty rare, huh?"
Pinned down, raw...
Right. We're having sex right now, raw.
This is the real deal, actual intercourse...
Miki's words slowly brought reality crashing back.
I refocused my attention on my penis, now fully buried inside her, the point of union.
"See? My pussy's clenching around your penis for the first time, all tight and fluttering. Can you feel that?"
A sweet, lewd whisper drifted down from above, accompanied by a coquettish smile, instantly pulling me back to reality.
For the first time in my life, I tasted the warmth of secret flesh.
As if my numbed senses were returning, my penis felt the soft squeeze, and pleasure began to surge through my brain.
Still deeply connected, Miki leaned closer, practically pouncing on me.
I tried to meet her extended tongue with mine, but just as we were about to touch, a sudden electric current shot through my entire body.
"Ah! Sh-shit!"
"Huh?"
I shouted after already sensing something wrong with my penis.
My hips trembled violently, my shaft convulsing repeatedly as if trying to expel a foreign object.
Trapped beneath Miki, still connected deep inside, I couldn't pull out or move an inch. Helplessly, I released semen into the depths of her womb, at her mercy.
