My On*Hole Academy [EN]: Chapter 148

I pressed Serena, who was lying face down on the bed with her stomach and thighs pressed tightly against it, and moved my hips against her.

Even in this position, I put my weight on her round, well-formed butt and vigorously thrust my hard-on into her.

Into the opening between her fair buttocks, visible beneath her uniform skirt…

Squelch, squelch, squelch, squelch…!!

“Serena! Serena!!”

Extremely excited, I rubbed my crotch wildly against her big butt,

and went to town on my little sister’s opening like crazy.

Exposed to the heated thrusting, Serena lay obediently face down, her ears flushed red, and let out a sensual breath.

“Yes! Yes…! Oppa [Older brother/term of endearment]…. I like it. I like it there…. I like you thrusting with your hard cock….”

……Tightly, tightly♡

No matter how hard I rubbed my crotch, all the impact was absorbed by Serena’s soft butt.

Serena responded by bouncing her big butt every time I thrust my cock in.

“Yes, yes…. I like it…. Oppa… you can cum as much as you want. From now on, it’s only for you, Oppa… my little sister’s opening….”

“Is it okay if I thrust like this, like this?!”

Throb, throb, throb, throb, throb♡

I thrust with suggestive hip movements, rummaging around as if searching, in the spot where I had just figured out Serena’s opening felt especially good.

“Yes, yes ohh♡♡”

Serena rolled her eyes back and gently shook her butt.

“T-That’s too suggestive and lewd. Oppa…!”

You’re the one who seduced me like that, you’re the one who stimulated my desire by shaking your butt like a female,

You think I’ll let you get away with acting pure now?!

I put my hard-on in Serena’s opening and shake it like crazy!

“Oh… ohooooo……♡”

Serena made her lips round and let out a hot breath.

Soon, ashamed of her moans, she buried her face in the bed, panting with only her eyes raised.

I wondered if there really were heroines who bit the bedsheets while having sex, but here she was.

I became an older brother and, without any shame, moved my hips like a pervert against Serena’s butt rhythmically.

Squeak, squeak, squeak, squeak!!!

“It’s okay for Oppa to thrust into the spot where Serena’s opening feels good. What’s the problem?!”

“Ugh… ungoo… Yes… Yesss…! Oppa can thrust into his little sister’s opening’s weak spot…!”

“Like this!”

I thrust my cock deep into Serena’s opening, a place not allowed to anyone but her future husband,

and stimulated Serena’s sensitive spots evenly by rubbing the walls of her opening with my big head.

Future husband? That husband is me!

“~~~~! Hng. Oppa…. I like it…. I like your opening……!”

Tap, tap, tap, tap.

Serena reacted by shaking her slender calves compared to her plump thighs, tapping the bedsheets with the tops of her feet.

Tightly… tightly…!

“Rather, I should reduce Oppa’s trouble. Serena should.”

“H-Huh…?”

“Which direction should I thrust?”

“J-Just a little…. Lower….”

Squeak, squeak, squeak, squeak, squeak♡

I swung my hips and thrust deeply into her opening, according to the weak spot of my little sister’s opening that Serena told me.

“Oh… Ohoht…!!”

“Tell me more!”

Serena’s butt twitched slightly and tilted to the side.

I knew instinctively that it was a movement to guide my cock to a pleasant spot.

“Should I thrust as is? Huh?”

“U-Uhm… if you thrust there… Ah… Serena’s opening… will be in big trouble…!”

Squelch!!

I pressed my hips tightly against Serena’s soft butt and thrust my hard-on in deeply.

Ooh…… Her opening is squeezing so much….

There’s so much vaginal fluid coming out, it’s no joke.

Tightly, tightly…….

Serena twitches her big butt and tightens her thighs.

You can tell how good it feels by looking at her leg movements. If she stretches her legs out as if stretching, she’s feeling it especially, and

if she crosses her ankles and clenches her toes tightly and trembles like now, she’s climaxing.

You can tell just by feeling the tight contraction of her opening with your cock.

“It’s a big problem. My opening is.”

“Ah… ahn…. Hooo…. Hooo…. The pleasure of my opening won’t stop…. Oppa…. Oppaah…. Soothe me. Calm me down…. I’m going to fly away…. Hng…. Hng…….”

Tightly, tightly…….

I’m not even moving, but Serena is straining, putting strength into her opening.

She’s groaning and panting in the afterglow of her opening’s climax.

It was truly an amazing reaction.

Isn’t this the first time an opening has had a real climax just by having a cock inside?

I shifted my weight forward, pressing down on Serena’s favorite part with my glans ‘firmly’…….

“Hng!!”

I gently stroked Serena’s head.

「Opening Touch」

“Ah…. Aahn……. I can’t calm down….”

Serena tilts her big butt from side to side, at a loss.

“Do it more…. Oppa, ugh, the fire won’t go out…. Ha… hak…. Oppa, put it out by rubbing it with your cock….”

“Like this?”

I immediately pressed down on Serena’s wrist and thrust into her opening forcefully.

Throb, throb, throb, throb, throb, throb♡

Serena’s juicy opening… so hot…!!

“I’ll put it out by rubbing it with my cock!”

“No… No… I feel like I’m melting. I feel like my opening is melting…. Hoo… hoo-oong…. Oppa. Oppa…!”

“Lift your butt!”

“Y-Yes…!!”

Slap, slap, slap, slap, slap, slap, slap♡

I slam down from above, as if scolding Serena’s big butt that’s rising up in an instant.

Serena, who had been resisting, is exposed to the outrageous perverted cock thrusting and gently rolls her purplish eyes back.

“Hng, hng, yes, yes…!! Oppa. Do you like my little sister’s opening…? Ah, ah, does Oppa… like my little sister’s opening… ?”

“I like it… It’s the best…! I can’t go back to the way it was before. Because I know where to thrust in Serena’s opening to make her feel good.”

“Yes, yes ohh♡ Really, you found out everything♡”

I’m thrilled just by hooking my hips on Serena’s butt that she’s offering and shaking my cock.

I press my hips tightly, tapping Serena’s clitoris with my balls.

Serena also sticks out her butt to match me.

Squelch, squelch, squelch, squelch!!

“Serena… Serena…! Is it okay if Oppa is Serena’s boyfriend?”

“I like it…… I like it a lot… I like being your husband too…! I want to have lots of babies with Oppa… and live happily…!”

Tightly… tightly…!

What man can resist when you say things like that and squeeze your opening so tightly!!

I rubbed my crotch against Serena’s butt and stirred her opening. I felt like I was going to cum soon, so I took a short break.

“It’s my butt that you like and rub every day♡”

Serena shook her big butt gently from side to side as if seducing me.

The visual is so shocking that it’s hot.

The wrinkled uniform skirt, gathered on her back, fluttered in time with Serena’s butt shaking.

“Serena!!”

Throb, throb, throb, throb, throb, throb♡

Unable to resist, I threw away my self-control and swung my hips forcefully, thrusting into Serena’s opening.

“Yes, yes ohhk!!? O-Ok, ok, ok, ok!!”

“I’m going to get all the value I’ve been horny for until now through your opening!”

Slap, slap, slap, slap, slap, slap…!!

During Serena’s golden opening time, where she lifts her butt and offers her opening, I thrust my hard-on in like crazy.

Squelch, squelch, squelch, squelch, squelch, squelch!!

“Ohohoht…! O-Oh, hoht…… Oho… ok!!”

Serena was beaten by my crotch until her butt rippled.

“I’m cumming in your opening! I’m cumming in your opening again. Serena!”

“Yes…. Ungoo……? Huh? Ah? Ah? Oh…!”

Serena, who came to her senses after being ravaged in her opening, trembled her butt and panted in a climaxed voice.

“In my little sister’s opening…… Ah, aah…… Oppa… as much as you’ve been horny… please cum…!”

Squelch, squelch, squelch, squelch!!

I thrust my hard-on, which was about to ejaculate, forcefully into her opening.

I held back until the very last moment and thoroughly ravaged Serena’s opening!

“Yes, hngeuk…. Hngik…. It… ik…!! My opening feels good…. It feels good again…. My little sister’s opening for Oppa, it’s going again…!”

“Who told you to get a cumshot from your Oppa while going?! You bitchy little sister!”

Slap, slap♡ Slap, slap♡

I shook my swollen cock, wondering how I was holding back, and tapped Serena’s clitoris with my balls.

“Hngheueung, no matter how much you discipline me by tapping me, I won’t listen to Oppa this time♡”

Tightly, tightly♡♡

I can’t stop! I thrust my hard-on in and rub my crotch against Serena’s butt that she offered♡

“~~~~Please get me into the habit of cumming from Oppa’s cumshot♡”

“I’m cumming in your opening!!”

Squelch♡

Bureureureureureut♡ Bureureureureut♡ Beut♡ Beut♡

I thrust my cock deep into Serena’s opening and ejaculated thick semen deep inside.

The baby room is instantly occupied with thick semen [A euphemism for the uterus].

Beut♡ Bureureureut♡ Beut♡

Serena trembled her big butt and squeezed my cock, which had become sensitive after ejaculation, tightly.

“I’ve gotten into the habit, Oppa♡”

Slap. Slap. I hit Serena’s butt with my palm.

“Yes, yes……. It’s no use even if you scold me. Because I’ve become an opening that goes with Oppa’s cumshot.”

“Do you like my cumshot that much?”

“Yes, I like it♡ Because it’s proof that Oppa made my little sister’s opening feel really good….”

Serena naturally lay face down.

I pressed my hips tightly against Serena’s butt and let out a deep breath.

The tremendous ejaculation…… The feeling of exhaustion was also tremendous. I hugged Serena in the most comfortable state in the world.

Serena was completely covered, but instead of feeling stuffy, she seemed happy and squeezed her opening tightly.

“Isn’t it hard to breathe?”

“…Press down on me more…. Oppa…. Like you’re raping me…♡♡”

Firmly.

I pushed my cock deep into my little sister’s opening and pressed down with the weight of my whole body.

Serena was under me, tapping the bedsheets with the tops of her feet and rejoicing.

“I like it…….”

“It seems like you’ve gotten used to doggy style a bit?”

“Yes… like this….”

Serena lifted her butt up again.

“Lay your upper body down tightly and lift only your butt, with that feeling…….”

I thrust into Serena’s opening again and slapped her clitoris with my balls.

“Ah, kyaa♡♡ Oppa, you’ve already gotten healthy♡”

“Serena is responsible with her little sister’s hole.”

“Yes. Do as much as Oppa wants. I’ll make you a meal right away too!”

That means,

The ultimate happiness of mankind.

It means she’ll realize eating, sleeping, and cumming [A crude term for ejaculating] ?

“Serena is the best!”

“Kya…… Aahn…! Yes, ungoht…!”

Throb, throb, throb, throb!

I put my cock back into Serena’s juicy little sister’s opening.

About 2 hours later…….

[Serena – Ovulating]

[Serena – Fertilization Rate 2,340%]

“Hnggeuk… Ung… Hngeut… O, ppa……. Haaht…. Woong…….”

As a result of stripping Serena and continuing to go at her doggy style.

The fertilization rate easily exceeded the limit.

Serena, who had been excessively used, lay on her side, panting with a waterfall of yellowish semen flowing from under her big butt.

“Hak…. Hak…. Hak…….”

I let Serena rest.

Even in the meantime, if I stick out my cock, Serena diligently sucks it to clean it.

While being cleaned, the huge boobies lying across the bed caught my eye.

“……Do boob job [Breast augmentation surgery]. Serena.”

“Boob… job?”

Now that there’s nothing to hold back, I began to unleash my sexual desire on Serena in earnest.
