Power Sex?
"Hnn... W-what are you doing? Hnn... Why... why are you just sitting still?"
Hana put on an air of nonchalance, as if nothing had happened, trying to sound composed. That composure shattered the moment I started moving my hips—not out of any gratitude for her master's consideration in waiting until the pain subsided, but to teach a lesson to this insolent slave who had the gall to provoke me instead.
—Schlick...
"Hnnngh!!!"
I hadn't even slammed into her roughly. All I'd done was slowly pull out the cock buried deep inside her, and yet there she was, biting down on the bedcovers and moaning. I laughed inwardly at the sight, gently stroking the softly rippling curves of her ass as her body trembled in fine shivers, recalling the powerful thrusting stance those male actors used in porn to make the actresses scream in pleasure.
So... spread the legs like this... bend the knees a little... grip here... lean the upper body forward just a bit...
Settling into a position I'd never tried in my life brought a strange awkwardness with it.
Mmm... I'll get used to it if I do it often enough.
With the two slaves I had now, and the ones I'd acquire later, practice would make perfect. Nodding a few times at the thought, I tightened my grip on the boundary between her slender waist and her full hips and drove my hips forward with force.
—Schlick!
My cock carved through the sticky, clinging folds of her wrinkled inner walls with a wet friction sound, and the moment it slammed down against her cervix, a pitiful moan spilled from Hana's lips.
"Uuugh!!!"
But the pleasure of thrusting for the first time in my life—the electric thrill racing up my spine—had me trembling so hard that her moan never even reached my ears.
Ohh!!! This! This is the pleasure of conquering a woman!
It was a sensation completely different from the woman-on-top I'd done with Selena. Marveling at it, I pulled my hips all the way back and then slammed down again, just like the man in the video.
—Schlick! Squish! Schlick! Schlick!
I never noticed the small hands clutching the slightly torn bedcovers trembling violently. I never noticed the tears beginning to gather at the corners of Hana's eyes as she bit down on the covers to stifle her moans. I simply savored the sticky wet sounds bursting out with every thrust of my hips, pounding mindlessly into the pussy that had been a virgin only moments before—until the urge to cum surged up.
Having never learned a single technique for controlling ejaculation, my mind already swallowed by pleasure, I forgot my vow not to finish until I saw Hana gasping in ecstasy. I slammed my cock down hard and poured out my seed.
—Spurt! Spurt! Spurt!
While I shuddered from the climax rising from my groin, the cum blasting from the tip of my cock pressed against her cervix flooded straight through her cervical canal and filled her womb.
"Haa..."
After an ejaculation that lasted far longer than anything from my previous life, I let out a long sigh of satisfaction as a pleasant weakness spread through my entire body. That was when Hana's voice reached me.
"H-hmph... Y-you were so full of yourself, and y-you're already done? Hnn... Th-then shall we rest now?"
Heh. As if S-rank potency would end with just this.
Even in my past life I'd easily managed three rounds in a row, and my potency now was far stronger than back then. Hearing her dismiss it made me laugh inside. I flexed my cock—stronger than ever—and made it twitch for her to see as I spoke.
"H-heh... N-not yet... Hnn... L-like last time... e-eight rounds... Hnn..."
"W-wait?! E-eight rounds, you saaaay?!"
I muttered as if I were still worked up and started moving my hips again. Hana flinched in shock and hurriedly bit down on the bedcovers, whatever she'd been about to say cut short.
I vowed to make her scream in pleasure with the merciless, powerful thrusting I'd learned from porn, and spent a long while pounding into the pussy that squeezed around me so thickly and greedily.
Then, just as I slammed my hips down hard for yet another thrust—I had no idea which number it was—
The legs I'd bent slightly to match the height, the ones holding me up in that so-called horse-riding stance while moving in time with my hips, gave out.
Ah? My legs...?
Panicking at the sensation of my body collapsing, I desperately reached for the bed. My body toppled onto Hana's back.
"Haa... haa..."
I just barely managed to keep from sprawling disgracefully across her sleek back, ending up half-draped over her instead, panting hard. A small voice reached my ears.
"Heh... Hnn... You were so full of yourself talking about eight rounds... Haa... A-already done? As expected... Hnn... There's a limit to what you can learn from porn, huh?"
"I-it's not over already! Haa... Th-this is just the beginning! Even if you beg me to stop, I'm going to keep going until sunrise... Haa... so look forward to it!"
What do you take S-rank potency for?!
Her laughing provocation made me snap. Forgetting I'd been pretending to be worked up, I shouted it out loud and tried to straighten my back and push myself up, putting strength into my legs.
But contrary to my bold declaration, my two trembling legs refused to listen. I collapsed onto Hana's back again.
...Huh? My potency is S-rank, though...? M-my stamina isn't bad either...?
I'd firmly believed that even as an FFF-rank master, I would be invincible in bed. Unable to accept reality, I just blinked. That was when Hana's voice, noticeably more relaxed, reached me.
"Heh... No matter how you look at it, hnn... you've used up all your strength... right? Haa... Why don't you just nestle into big sis's arms and take a little nap?"
Even if she was older, hearing a slave treat me like a child—especially in bed—was something I absolutely could not tolerate. I put strength into my legs once more, determined to stand.
"Hnnph!"
I clenched my teeth and poured every last scrap of strength I had into my legs. After a long struggle, I managed to plant my trembling feet on the floor and stand.
"Haa... haa... Not yet... Not yet..."
Supporting myself on legs that looked ready to buckle at any second, I panted and muttered. Hana's body gave a little jolt as she spoke.
"H-hmph. C-can you even move? Don't waste your strength for nothing. W-wouldn't it be better to just rest?"
I let her provocation go in one ear and out the other, steadying my mind.
Haa... haa... Right. They always say as long as you have the strength to lift a spoon, as long as you can step over a threshold, you can do it. There's no way an ultra-virile man with S-rank potency like me would collapse like this. Hoo... hoo...
Repeating those floating rumors to myself, I steeled my resolve and slowly began to move my hips.
—Schlick... schlick... squish...
Every time my cock slowly, gently thrust into her pussy, wet friction sounds spilled out, and from Hana's mouth—the same one that had been provoking me—came a moan laced with fluster.
"Hnnph?! Hnn!"
My legs were still trembling, but they hadn't collapsed like before. The fact that I'd shut the mouth of the girl spouting arrogant words filled me with confidence. Imagining the pleasure-soaked cries that would burst from the lips still biting the bedcovers, I gradually sped up the movement of my hips.
And then, soon enough—
I collapsed.
Th-this can't be... I... I...
The miserable realization that my body couldn't even manage a proper piston motion tore a desolate sigh from me before I knew it.
"Ah..."
"Haa... heh... Hnn... That's why I told you not to push yourself and just stay by big sis's side... Huh?"
Hana, who had been swallowing her moans and gearing up for another provocation, stopped short at the sound of my powerless voice. She closed her mouth, gauged my mood, then carefully tried to console me.
"Uh... well... Y-your leg muscles just got startled by the rough movements they aren't used to... I-if you practice little by little, it'll be fine. Exercise is like that too, right...? S-so don't get too down..."
The moment my knees hit the bed again and every last scrap of pride crumbled, I muttered self-deprecatingly.
"Even then, I can't even make one slave feel good..."
As I trailed off in a dejected voice, Hana hurriedly spoke up.
"I-it did feel good! Yeah. I-I just held it in from the start because... if I showed how much I liked it, I'd look like some... lewd woman. I-it felt good, okay. I-I was right on the edge of cumming."
Hearing that she'd felt pleasure lifted my spirits a little. I carefully asked,
"Really...?"
"O-of course. So c-cheer up and keep going. Uh... well... m-maybe a position where the legs that worked so hard to make me feel good can rest a bit... Y-yeah. Just staying like this and putting your knees on the floor might be fine... What do you think?"
As if insisting she truly wanted to continue, Hana pressed her springy ass back against me, proposing the position that first comes to mind for doggy style.
"S-should we?"
Seeing how much she seemed to want it, my self-esteem began to recover little by little. When I asked again, Hana gave a small nod.
"Y-yeah. Then once some strength comes back to your legs... d-do it like the first time again... Yeah. That should work... S-so hurry..."
"R-right! I-it got a little weird, but I can't end your first time like this!"
Her urging restored my confidence. I declared it loudly, then firmly gripped her full hips and slowly began to move my waist.
—Schlick. Squish. Schlick. Schlick.
"Hnn. G-good... Hnn... Haah... T-too... Hnngh!"
With every gentle piston thrust, the lewd friction of cock rubbing against pussy mixed with the sweet moans Hana no longer bothered to suppress, dyeing the room in their sound. That strange harmony continued until even the muscles in my waist stopped listening and I could no longer thrust at all.
