Jyak, jak.

The sound of Umanko’s footsteps wasn’t the sharp, high-pitched pakara-pakara of a horse from a period drama opening.

I was riding her in a reverse shoulder-carry position, clinging to her head with my whole body so I wouldn’t fall off.

Jupo, jupo... jupo.

The sound of Umanko’s fellatio was exactly like stroking a lotion-drenched onahole.

Since I don’t like looking at male cocks, I always watched solo female or lesbian porn. Lesbian anal expansion videos were the absolute pinnacle that perfectly matched my tastes. Because of that, I had never watched porn with male actors, so I didn’t know what a real blowjob sounded like and couldn’t compare it to Umanko’s.

The sounds actresses made when sucking on a dildo before anal insertion were gentler—more like pero... chupu.... They didn’t make that loud jupo jupo noise like Umanko’s blowjob.

Jupo, jupo... jupo.

She was sucking the entire shaft into her mouth...

"T-That’s not a carrot, you know..."

I tried to gently scold Umanko, but she didn’t stop sucking. Just when I thought the suction had weakened and it was ending, she readjusted her grip on my cock with her mouth.

Maybe she liked the taste of my precum, because the tip of her tongue started playing with my slit in circles. Then she wrapped her whole tongue around the glans again.

"Uuh... ah!"

The vibration from running made my cock slide deeper into Umanko’s throat. My dick tried to point upward, but her throat angled downward, so the glans was being pressed firmly downward. Because Umanko was running, her body rocked up and down rhythmically, and the folds deep in her throat kept slapping against my glans.

Even though the base of my cock felt pain from being bent downward, the tip was slick and felt incredibly good. It was like overconfidently shaking a Tenga with a hard plastic outer shell too violently. Once, I had spun an onahole around my erect cock, the momentum made it fly off, and I came instantly, splattering the room... After that incident, I stopped doing any onahole handling that involved rotating the base.

This was the first real stimulation at the root in a long time.

There was no way I could hold back...

"I-I’m cumming... ugh..."

Byuru...

I ejaculated.

But it wasn’t a complete orgasm. I couldn’t fully cum. Because my cock was bent too far downward, the vas deferens or urethra was probably compressed. Sperm was stuck in a traffic jam inside the shaft. The incomplete ejaculation left my entire cock feeling cramped and uncomfortable.

"Uuu... I want to cum properly..."

If this were an onahole, I could adjust the angle myself and stimulate it again for a satisfying finish. But Umanko didn’t know my intentions and just kept running.

"Kh..."

Desperate to release the remaining semen in my shaft, I leaned my body forward. I shifted my entire weight toward Umanko’s back to return my erect cock to a more natural angle. The ground rushing past at terrifying speed was scary, but I endured it for the sake of ejaculation.

"Ugh...! Ah...!"

The slight shift in my position combined with Umanko tilting her head upward suddenly released the pressure that had been pinning my cock down.

Byubaaaaaaa! Dobyububububu...!

"Aaah, uuu...!"

It shot out with such force that it felt like you could hear the ejaculation even from deep inside Umanko’s throat. My shaft pulsed violently, and Umanko’s teeth kept bumping against the base, sending pleasant pain through me. The post-orgasm exhaustion nearly made me fall off Umanko’s back, but she grabbed my waist and kept me from falling.

"A-Are you okay...?"

Having a cock shoved down her throat and pumped full of semen must have been painful for Umanko. But my worry was unnecessary.

Gulp, gulp...

As if it were the most natural thing in the world, Umanko swallowed every drop of my cum. Then, apparently liking it very much, she immediately started sucking again without rest. This time she didn’t just lick the glans like before. She sucked with steady chuu chuu sounds, like a butterfly drinking nectar from a flower.

"Ah... aaah..."

For someone like me who usually jerked off hard and fast with my hand or an onahole, this gentle squeezing was a rare sensation.

"Haa... haa..."

My erection wouldn’t go down, but it seemed I still had some time before the second ejaculation. I hoped she would just gently finish the blowjob like this. I really didn’t want to die from falling off during a horseback blowjob. I straightened my posture and stroked Umanko’s head to calm her.

Chupu...

Pero...

Maybe my kindness got through to her, because Umanko started sucking more gently too. The tip of her tongue licked along the shaft while avoiding direct stimulation of my sensitive glans and frenulum.

Eventually, saliva overflowed from her mouth and flowed down to my balls. The cool wind on my saliva-soaked scrotum felt pleasant. My penis almost started to wilt from the cold, but Umanko’s gentle tongue kept giving me soft stimulation. Not only did my erection stay strong, my cock gave a heavy throb and felt like it had even grown slightly larger.

"Haa... haa..."

I used to feel it was wasteful to throw away a disposable onahole after one ejaculation and would try for a second round while still inside, only to go soft. Yet Umanko’s gentle fellatio kept me hard indefinitely.

I didn’t know whether this girl with the childish face was a blowjob master, or if the combination of the reverse shoulder-carry vibration and her tongue technique created a miraculous synergy... All I knew was that it felt amazing.

My penis started aching again, and I quickly wanted to cum once more.

I wanted to thrust with my hips. But on her swaying shoulders, I couldn’t move my waist. I couldn’t even shake her head. I was completely unable to stimulate my own penis of my own will. My cock was entirely at the mercy of Umanko’s palms—no, her tongue. Whether I came or was edged was completely up to her. How frustrating.

"Aaah...!"

Umanko bounced hard up and down. She must have jumped over a rock. The impact made my body bounce, and I started sliding forward off her. Umanko quickly placed both hands on my ass and pushed me back up.

In doing so, my buttocks were pulled apart and my asshole spread open.

A single stream of cold wind slipped inside.

"Hyaaan!"

The unknown sensation finished me off, and I slowly came again.

Byu... ru...

Byuru...

...Byubyu... byuu...

It was a strangely gentle, slow ejaculation...

Pyuru...

Ru...

It still wouldn’t stop. It kept flowing out little by little.

"Ah... ah..."

Chupa chupa...

Even while I was cumming, Umanko continued sucking. Having apparently taken a liking to the taste of my semen, she quickly figured out where it was coming from. The frequency with which her tongue tip teased the slit in the center of my glans skyrocketed.

Churu, churu...

After that, I lost track of time and came over and over again.

The caress of that secret cleft at the tip of my cock felt so good that I just kept ejaculating endlessly onto her tongue, nearly losing my mind. In short: "Secret Cleft Caress — Infinite Tongue Ejaculation Variant."

They say a single ejaculation releases 300 million sperm, so after reincarnating, my total must have already surpassed 40 billion...

The sweet, gentle climax continued endlessly. I lost all sensation in my penis. Pleasure lost its shape, and my cock seemed to fuse with Umanko’s mouth-pussy, drifting in a sea of saliva and semen.

Eventually, Umanko stopped running. When I was lowered to the ground, I sat down and couldn’t stand back up. My knees were shaking violently from the continuous orgasms.

I looked around for Iria, thinking we had reached our destination, but she was nowhere to be seen. The area was just wasteland with sparse low shrubs.

"I-Iria...?"

Wasn’t the chestnut Umanko I was riding supposed to be chasing the white-haired Umanko that Iria was riding? Did we get separated?

"Iria? Iria! Where are you?"

There was no answer.

Umanko was supposed to be smart. Didn’t she say she would chase after her companion? Getting lost in another world was extremely bad. This was mostly undeveloped land—there was a real chance we might never encounter another human again until I died.

"H-Hey, Umanko."

The chestnut Umanko seemed aware she had gotten separated and awkwardly looked away. Don’t tell me she was so focused on the blowjob that she wasn’t paying attention to our surroundings?

Ugh... I feel dizzy.

"Haa... haa..."

I had been on her back the whole time without eating or drinking, just lazily ejaculating repeatedly, so my throat was parched.

"W-Water..."

I looked around, but there was no pond or river. The scattered shrubs didn’t seem to have any juicy fruit either.

Hearing my dry, raspy voice, Umanko finally seemed to notice my condition and scanned the area. She had a higher vantage point while standing, but apparently couldn’t find anything either.

Sitting was painful, so I lay down on my back.

The sun was directly south. It was midday. Several hours must have passed since we left in the morning. This was bad. If things continued like this, I would die of thirst in the middle of an empty wasteland. I wanted to go look for a village or a river, but after all the continuous blowjobs, I had no strength left in my legs or hips. After last night’s 50 consecutive ejaculations and now another 20 or so gentle, relaxed orgasms, my body might have already run out of fluids.

Cause of death: dehydration from excessive ejaculation.

I didn’t want to die like that. If I was going to have a sex-related death, I at least wanted to die while inside a pussy.

Umanko, who had been continuously drinking my semen, seemed to have plenty of hydration and looked energetic.

Ding.

A system message echoed in my brain.

Masaharu Oi’s skill "Erotic Warrior" has leveled up from 5 to 6.

...No, I’m not happy about leveling up at a time like this at all.

Wait, level 6? Wasn’t it 5?

I must have fallen asleep last night and missed the system message. Anyway, the Erotic Warrior skill wasn’t helping at all right now...
