Thank You for Using Me

Schlck—schlck—thwack—squelch—
"Ngh…! Guh…!"
I was lying on the bed, being used by a man. Yes—used. No matter how much I struggled, no matter how much it hurt, the man simply looked down at me and kept rolling his hips. He moved like he was working an onahole, groping my breasts however he pleased.
"I've never seen a pussy with so many weak spots. Does every inch of you feel good?"
"I-I'm so… nngh♥… rry… kyaang♥…!"
Every time he drove his hips forward, my womb screamed in bliss as his cockhead battered it. Is a woman's body… just like this? You get fucked a few times and that's it—you go limp, you can't do a thing, and you lie there completely defenseless in front of a man?
"This must be the spot."
Schlck-schlck-schlck-schlck—♥
"Kyaang♥… ah, no… not just there… I can't♥…!"
He buried himself to the hilt and focused on grinding his glans against my cervix. The massive cock occupying my belly had completely overpowered every inch of me. I shuddered at the sensation of a woman's most precious organ being used however he liked. My vision swam. My hips lifted off the bed of their own accord, arching so that my cervix pressed even tighter against his cock.
"Ahk… aaahk…♥!"
I clutched my head and shook it, terrified of how ridiculous I must look. The man gazed down at me and smiled. Then he gripped my pelvis, drew his hips all the way back—
"Ah… no—"
THWACK♥—!
"Kyaaaa… aaaa…♥"
—and with a single thrust, turned me into an idiot all over again. The air rushed out of my lungs. I couldn't breathe. Every scrap of strength in my body had concentrated in my pussy, forcing me to feel the outline of the cock inside me even more clearly. Thick. Hot. Hard.
I'd realized this after becoming a woman: a big cock was something a pussy simply could not defeat. Just by invading your body and moving however it wanted, a woman had no choice but to writhe, drunk on pleasure. No matter how hard I clenched down, no matter how fiercely I tried to bite back, it only grew harder—as if it liked the resistance—and tormented me even more.
"Kyaa… aaa…♥ haaakh…♥"
When I finally recovered enough to gasp for air, blood rushed through my whole body and the flesh of my pussy clung to his cock in greedy little pulses. He felt it. A thin smile crossed his face as he asked,
"Can you feel it, Warrior? It's in this far. This far."
"Ngh! Ahk♥…!"
He tapped my lower belly with a thick fingertip—right where his glans was kissing my cervix. Hit from the outside and the inside at once, I threw a hand down to protect my womb.
"I-I can feel it… s-so… don't hit it♥…"
That pitiful surrender made him burst out laughing. Then he started rolling his hips in slow, grinding circles, and I thought I would lose my mind.
"How about this? I imagine it's smearing you nice and wide in there."
"Ahk… kyaaaakh…♥"
A scream of a moan tore out of me. His cock swept back and forth in a fan, tormenting my insides. My melted, clinging walls wept slick in a desperate plea for him to stop, but that hard cock showed not the slightest sign of softening as it slowly savored every inch of my flesh.
"I-I hate it♥… that… stop it♥…"
Every time the slit of his cockhead, pressed flush against my cervix, shifted even a little, a dizzying rush of pleasure hit me so hard I thought my brain might break. I couldn't do anything. I couldn't go anywhere. I was drowning in it. And then he said,
"Feels good. This entrance to your womb. Nice and springy—perfect for scraping my glans."
"Kh… nngh…♥"
I was being used. The most precious place a woman had was being used for nothing more than making a cock feel good. It was humiliating. It was infuriating. But the thing that made me most wretched of all—
"Let's try up and down this time."
"Khooooohk…♥!!!"
—was that every time he added another mocking little trick, my entire body screamed with pleasure.
"Still feel good? Honestly. Every last one of you is filthy. You Warriors."
"Khhhk…♥"
Tears streamed down my face. That insult hadn't been aimed at me alone—it had swept up every one of my comrades with it. I wanted to snap back right then. That it wasn't true. That I was the only pathetic one. That he should leave the others out of it.
Schlck-schlck-schlck-schlck—♥
"Kyaaakh…! Kkyaang…♥!"
But what came out of my mouth wasn't a protest or fury. It was the cheap, vulgar scream of a female. Even looking this much like a mess, I couldn't do a thing except lie there and be used. It was wretched. It was shameful. And as if my feelings didn't matter in the slightest, he issued another order.
"Thanks to you, I'm about to finish. I'll need a favor."
"……?"
I clenched my teeth at what he said next and glared up at him. But the instant my eyes met that cold, expressionless gaze looking down at me, I understood. He had no intention of taking back the mockery. And I had no choice but to obey.
"Then here I go."
Schlck…♥ schlck… thwack-thwack…♥ thwack-squelch-thwack…♥
"Kh… ah…♥ aaa…♥ nngyaaaakh…♥!"
The moment he started thrusting again, my pleasure-soaked body began following the order on its own. I spread my legs even wider and moved both hands up beside my head. And when the moment ripened—
Splurt—splurt—throb—throoob—♥!
"Kh… nngh… ah……♥"

I did exactly as I'd been told. I threw up a double peace sign, laying bare without a shred of restraint that I was a submissive female who had surrendered completely to pleasure. Feeling that thick, clotted semen invade my womb, I sank into a climax so intense my thighs shook.
"Hah… I really can't resist this. Making you do something this pathetic while I pump you full."
"Kh… nngh…♥"
Tears spilled endlessly at his little review, but I held the pose. To take this much humiliation and not even manage a single act of resistance—to have to play along and fawn. The shame I'd felt with my seniors had been child's play. I understood that now with my entire body.
"Good. Get up now. Stop with those idiotic hands."
"……A-are you… forgiving me…?"
I braced myself against the bed and pushed my body up with difficulty. He tilted his head as if he couldn't imagine what I was talking about.
"Just this much? I had my life threatened, I'll have you know."
"…What am I… s-supposed to…"
"What are you even asking? Crawl. I'm going to need that pussy a while longer."
"……Yes…"
I got up on unsteady legs and did as I was told. I dropped onto the bed on my stomach and pushed my ass back, and he let out a whistle as he took me in.
"What a sight. What a sight. So big, so white, and springy on top of it."
"Ngh…♥"
He kneaded my ass as he lined his cock up with my pussy. Then he started rolling his hips at once.
Thwack—thwack—thwack—squelch—♥
"Ah… kyaa…♥ aaa…♥ hnn♥…!"
The impact on my womb was far worse than it had been missionary. I tried curling my hips, rounding my back, anything to dodge the cockhead hammering my womb—
"Where do you think you're going? A Warrior doesn't run."

SLAP—!
"Kyaakh…!"
He cracked my ass hard enough to force my hips straight again.
Thwack—thwack—thwack—
"Ahk♥…! Aaahk…♥!"
Freed of my curling, he started striking my womb with his glans even more skillfully. The shock traveled up my spine and felt like it would burst out through the top of my skull.
"Mmm. This rebound. Excellent. I could do this all day."
"Kyaaaang♥… aaa… aaang…♥"
The way he was appraising me made my blood run cold. I shook my head, begging him not to mean that. The stinging pain in my ass vanished for a moment—

"I don't care for that attitude. You could at least say thank you."
"Kyaaaang…♥"
—and his cock drove even deeper, pinning my head down. He ground my face into the sheets as he pressed me.
"Say it. Say thank you."
Pinned with nowhere to run, I rubbed my face into the sheet and cried out wretchedly.
"Th-thank you… thank you…!"
"Thank you for what? Say it properly."
"For f-fucking me…! Thank you…! Thank you for using me…!"
"Mm. Good enough."
Apparently pleased with how obedient I'd become, he kept his grip on my head and yanked off the only thing I was still wearing—my shirt. Cold air hit my fever-hot shoulders and the small of my back, and a dizzying rush of exposure flooded me: the sharp relief of being stripped, and the staggering shame of having my entire back laid bare.
"Now. Brace yourself properly on the bed. Sex… no. An apology only has value when you make it yourself."
Even at this point, he kept talking as if what he was doing was perfectly justified. Anger surged up in my throat—and then he knocked my womb a few more times, and I didn't care anymore.

Squelch—squelch—squelch—
"Ah… aaa… aaaa…♥"
I moved my own ass in time with the way he gripped my pelvis and pulled. The strokes grew shorter and shorter, until the wet slap of my overflowing, slick-soaked ass hitting his groin rang through the room.
"Nothing you'd like to say before we finish?"
He asked it as he gave my ass a casual smack. I bit my lower lip in fury—and then the words tore out of me in a voice thick with pleasure.
"I-I'm sorry…! Please forgive me…!"
From somewhere I couldn't see, his laugh spilled down over the small of my back. Humiliation brought tears to my eyes even as I felt the cock inside me swell all at once, and I braced for the impact that was coming.
Thwack—thwack—THWAAACK—♥
"Kh… haahk…♥"
A jolt hard enough to sting my ass, and my womb was hammered without mercy. And from the slit of his cock, jammed against my cervix—
Splurt—throb—throoob—!!
"Kh… aaa… aaaa…♥"
—that thick, clinging white filth flooded me once more, packing my womb to the brim.
