I’m the Only Male Knight in a Chastity-Reversed World, and When I Enrolled in a Female Knight Academy, I Somehow Got Treated Like a Hero — Dominating with an Unparalleled Skill That Makes Me Stronger the More Sex I Have - 5

Chapter 5: Nail-Driving Piston ♡

ーーーーーーーーーーーーーーーーーーーー

“Even after you’ve already come once, it’s still rock hard… ♡”

Cassandra smiled fearlessly while staring at my engorged shaft.

“I like a male with a good spirit. It makes me want to ravage you until you cry.” 

“That doesn’t sound like something someone who was moaning and squirting earlier should say.”

“Kakakah! You’ve got a smart mouth, don’t you?”

Speaking delightedly, Cassandra pushed me down onto the bed. Keeping her hips raised, she straddled me in a crouching position.

“I’m sure you heard the knights talking about it. My nail-driving piston cowgirl. It’s an ultimate technique that has broken countless men before. Up until now, no one has been able to endure a single minute of my nail-driving piston cowgirl. They all end up finishing before I even get a chance to feel good.” 

“Well,” I said defiantly, “I look forward to it.” 

“I can’t wait to see how long you can keep up that cocky attitude.”

Distorting her lips in a similarly bellicose way, Cassandra lowered herself onto me.

Squish…!

“Nnn… ♡”

My protruding shaft was swallowed by her vagina all the way to the root. Her insides, overflowing with love juices, accepted my rod without resistance.

“What a hard, thick, wonderful cock… ♡”

Having said that, Cassandra looked down at me and entered her battle stance.

“Now then. Let’s see how many seconds you can hold out.”

With those words, Cassandra began to move her hips up and down. A body trained to perfection. The hot folds of her vagina coiled around my shaft exquisitely.

“Ugh…!”

Enveloped in supreme pleasure, a moan escaped me in spite of myself.

“Different from your average woman’s, right? Eh?”

Cassandra smiled with satisfaction at my anguished expression. Then, she increased the speed of her hip movements.

“Kh…!”

The nail-driving piston cowgirl was terrifyingly powerful. It felt as if she were trying to wring out not just my semen, but my very existence. What made such a thing possible was Cassandra’s robust physique.

An ordinary man wouldn’t last long. He would have surely finished long ago. But I was enduring. I couldn’t just stay silent and let her make me come like this. Reaching out with both hands, I kneaded her protruding breasts. I caressed the tips with my thumbs.

“Nnh… ♡”

Cassandra’s body gave a sudden jolt.

“What’s this? You’ve still got some fight left, huh? ♡” 

“Something like this is nothing.” 

“Aren’t you a sturdy one. Any other man would’ve broken by now. Kreto, it seems you’re no ordinary person.” 

“I’ve been training, after all.”

I hadn’t trained myself so softly as to be broken by something like this.

“Fine then. Let’s see who finishes first… It’s a contest…!”

Cassandra increased the speed of her pistons. Violently, as if driving a nail, yet passionately, she slammed her hips down. I attacked Cassandra’s breasts and moved my hips in time with her pistons.

“Nnh ♡ Kuuu… ♡”

The waves surged for both of us, and I could tell the limit was approaching. However, I couldn’t back down. Both I and Cassandra gave our everything to make the other finish first. And finally, the moment of climax arrived.

Splurt! Splurt! Splurt…!! 

“Khuaaaaaaaaaaaaaah… ♡”

We finished at the exact same time. Simultaneously with Cassandra reaching her peak, I too spat out the desire I had been holding back. For a moment, the stimulation was so intense my mind went completely white.

“…Kuku, it looks like it was a draw.”

Once the waves receded and silence returned, Cassandra laughed happily. When I pulled my shaft out, a massive amount of semen overflowed from her vagina.

“Surely you’re not going to tell me you’re at your limit already?” 

“I’ve still got plenty left in me.” 

“That’s a good answer… ♡”

After that, we continued to join our bodies until morning came. I stayed with Cassandra until she was thoroughly satisfied. We coupled until it felt as though our bodies were melting into one another. My skill allowed me to gain mana through sex with the strong. I’d do anything to grow stronger.

By the time morning arrived, the sheets were soaking wet with our bodily fluids. While bathed in the morning sun, Cassandra spoke with satisfaction.

“I’ve bedded many different men up until now. But there wasn’t a single one who could satisfy me. Every last one of them was boring. But Kreto, you seem to be different. You’re the first man who has been able to satisfy me and see the morning without breaking.”

Saying so, Cassandra whispered while stroking my hair.

“Kreto. I’ve taken a liking to you. From now on, I’ll dote on you every day.”

From then on, we repeated the act nearly every night. Coupling with Cassandra was like the mating of beasts. Rather than simply joining skin to skin, it was as if we were making each other’s flames roar violently. Every time I joined body with her, I felt myself gaining immense power.

On the other hand, I never neglected my sword training. Having spent time with her, I realized even more that Cassandra’s strength was the real deal. Cassandra rarely gave me any direct instruction. She didn’t offer, and I had no intention of asking for teaching. I learned through the clashing of our swords.

Training with the sword in the morning and devoting myself to sexual acts with Cassandra at night. By working hard every day with a world-class practitioner, I grew at a phenomenal rate. Then, one day. I was able to land a blow on Cassandra for the first time. A one blow was just one blow. There was no denying it.  Even so, for me, it was a greater step than anything else.
