My ultra-sensitive sister's erotic pussy feels quite different now.

Simply grabbing her buttocks makes her twitch.

"Did your pussy feel better, Serena?"

"Mm, oppa♡"

With a swift motion, Serena lay down and... assumed the doggy-style position for me once more.

Thrusting her ample derriere backward as if inviting me to penetrate her deeply...

"Now, oppa, shall we have sex?"

"Really? Is it okay if I put everything in?"

As I placed my hand on her waist, Serena's body shuddered.

"Uh? Wasn't everything in already?"

I forcefully inserted my erect cock into Serena's prepared pussy.

*Swoosh* ♡

"Oh my♡"

Serena's reaction was completely different.

I slid my hard cock into her soaked and sensitive vaginal hole.

Filling her completely, our bodies pressed tightly together as I nudged her cervix with a tender *kiss* ♡ *kiss* ♡…

Serena's raven-haired younger sister's enormous breasts were downright maddening. At a single glance, her backside was stunning: voluptuous hips and the outline of her large breasts visible even from behind. Her slim nape and lovely side profile were simply perfect.

"Thrust, thrust harder... like that… Ah…♡"

Serena murmured joyfully in a high-pitched tone while gently swaying her hips.

"Oh, brother… please… go gently… be gentle with me."

Behold the lewd sister who clings to my bare, erect cock… I'm going to do it like this!

"I won't give our Serena to anyone!"

Gritting, squelching, squelching, squelching!

I thrust my erect member with such force that Serena's ample bottom rippled!

"Eek!?"

"Take it, pussy!"

Feigning professionalism with her posture, I scolded Serena, whose buttocks were prominently displayed. I slipped my throbbing member into the inexperienced, young sister's pussy!

Squelch, squelch, squelch, squelch, squelch♡

Serena was at a loss, her pussy taking a defenseless pounding. The stimulation must have been too much, as she tried to dodge from side to side. But with a firm grip on her waist, I relentlessly pursued her retreating pussy with my engorged cock.

*Squelch-squelch-squelch-squelch-squelch-squelch-squelch!*

"Ah! Ah! Ah! Ah…!? My… my, oh, oh♡ My little sister's pussy♡ If you use it like this, oh, oh, it's not right. Big brother♡♡ Big brother, ah, ah, your little sister, your exclusive little plaything♡"

"Offer me your ass!"

"Oh, oh-ho♡♡ Yes, yes♡♡"

*Creak-creak-creak-creak-creak♡♡*

Serena's pussy is severely paying the price for taking her brother's cock♡

A heroine's pussy in this erotic game has only one choice: to make her big brother happy!

Thrust the erect dick inside!

Ah~~ This is the sweet and loving little sister's pussy♡♡

Take it all; make up for all the arousal up until now!! Thrust the cock into her pussy with force!

"Huh? Wha? Oh?"

*Squelch-squelch-squelch-squelch-squelch!*

Even now, it seems she can't grasp the situation, making such adorable sounds♡

Serena's virgin pussy tries to wiggle her ass to avoid overstimulation, but her waist is held firmly in place, preventing her escape.

Thrust the erect dick forcefully into her immobile pussy!

*Squelch-squelch-squelch-squelch-squelch!*

"Uh… mmm… ahh…! Ah, ah, ah, ah♡"

*Quiver, quiver♡*

Serena's ample breasts swayed enticingly beneath her shirt, unrestrained by a bra. I immediately straddled her body as if covering it from above, kneading her breasts and rocking her waist from top to bottom.

Thrust, thrust, thrust, thrust, thrust, thrust!

"Oh, ohh ♡♡"

"Serena! Serena…! Your tits, your pussy, and your asshole are all mine! All mine!"

"Yes, everything belongs to you!"

Serena raised her shapely buttocks invitingly. She struggled as I squeezed her breasts.

Ah, so tempting♡

As I vigorously pounded her lustful ass with my hard cock, Serena's waist gradually sank to the floor.

"Oh, are you going down?"

"I'm sorry. I'm sorry, my love. Heh. Mmm♡♡ I'll try harder. Yes…"

I gripped Serena's full breasts as if crushing them, resting my waist against her soft buttocks and rocking back and forth.

Squeak, squeak, squeak, squeak, squeak!

Serena's pussy oozed with juice as she lowered her hips more and more. It seemed she couldn't withstand the forceful thrusts from above.

"Oh, no. My little sister's tightness... I can't take it if my beloved brother fills me with his cock…♡"

"Are you giving up already?"

"No! One, two♡"

Serena clenches her stomach and holds her breath.

Her big ass protruding invitingly♡

As if tearing the golden pussy time her sister has created into tiny pieces, he forcefully and persistently thrusts his cock into her slick opening!

*Schlick-schlick-schlick-schlick-schlick-schlick-schlick-schlick♡♡*

Serena arches her head back as she receives a barrage of unrelenting thrusts, gasping for breath.

"~~~~~~~~~~~!!"

*Squelch-squelch-squelch-squelch-squelch-squelch♡♡*

Serena rolls her eyes, bracing herself with her big ass outstretched, clenching her stomach tight until the most precarious moment.

Her pussy clings and contracts incredibly tight.

Serena's massive ass is driving him wild!

With a rub-rub-rub-rub-rub, he pushes his erect cock even deeper inside her.

The pleasure of gripping Serena's huge breasts and rocking her hips ♡♡

"Serena! Serena… You're amazing! Your sister's curves are the best."

"Huff, huff… Hnng…"

Serena's face flushes red as she holds her breath.

"Cum in Serena's pussy. Serena… Cum in Serena's pussy again."

As I squeezed her breasts and thrust forcefully into her cunt, Serena gasped for breath and collapsed.

"The lower pole…!"

"This guy."

I vigorously pursued Serena's mound, thrusting powerfully into her pussy that had fallen forward.

*Thrust, thrust, thrust, thrust!!*

"Heh, hiang!! I'm sorry, Oppa. My pussy is throbbing. I'm sorry that I'm a little sister who can't stand it."

"Can't even handle one round of doggy style?"

Ah~~ Serena♡♡

I rubbed my cock against Serena's ample ass before inserting it and rocking her. All the while, she clenched tightly, desperate for my cock to slide inside her pussy and relinquishing control as I moved♡

"I'm sorry I'm a sister who can't perform well in sex♡ Yeah… Ng… Ngooh…!!? Instead, you can use my pussy, my pussy hole as much as you want… Ah… Ah… Please use Serena's little sister's pussy!"

"Lie down comfortably, huh?!"

*Thrust, thrust, thrust, thrust!*

Every time Serena tried to lift her ass, I forcefully rammed my erect cock into her, as if driving it into the bed.

Serena groaned and was desperate to somehow fend off her brother's penetration with her buttocks.

"You're so good, Oppa ♡ Using your little sister's hole all by yourself, I'm so proud of you.

I placed my weight on Serena's buttocks and thrust my cock deep inside her.

*Thrust ♡ Thrust ♡ Thrust ♡ Thrust ♡*

"Oh, oh, oh, oh ♡"

Serena, slightly lifting her hips, gently bounced her ass every time I pushed my cock into her.

"Oppa, you're so good at it ♡ If you're aroused, you can take care of your little sister's pussy, right?"

"I can!"

"Yeah, yeah. You can skillfully use your little sister's pussycat all by yourself. One, two ♡ One, two ♡♡"

Being able to use your little sister's pussy makes you a proud older brother.

"OnaAka" is the best!

In sync with Serena's cheer, I sway my hips.

*Thrust! Thrust!*

"One… two…"

"Your cock's amazing... Serena…!"

"If your cock's hard, Oppa... uh… can you cum inside your little sister's pussy?"

"Of course, I can."

"Wow, you're amazing... Ah, so good ♡ So good ♡ Oppa's cock, keep it up!"

Serena gently swayed her ample hips from side to side.

"Let's thrust our engorged cock into my sister's pussy♡"

"Serena!"

*Slurp, slurp, slurp, slurp, slurp, slurp, slurp♡*

I vigorously slammed my hips into Serena's royal derrière, heatedly engaging in depraved carnal coupling.

Sex. Pregnant sex with Serena! Filling her up. Unconditionally impregnating her pussy♡

「Pregnancy Guaranteed: Cumming Inside」

[Serena: Ovulating]

[Serena: Fertilization rate: 120%]

"My baby! Give birth to my baby!"

"Yes, yes, oh♡ I'll give birth. I'll give birth. I'll bear your child. Let's slide your cock through my sister's hole and feel even better♡"

*Squelch, squelch, squelch, squelch, squelch, squelch♡*

Driving my cock forcefully into her royal posterior, making her pussy juices burst, and squeezing her breasts!

"Oh, oh, oh, oh, oh♡"

*Thrust, thrust, thrust, thrust, thrust♡♡*

"Fill her pussy. In Serena's pussy♡ Fill her pussy!"

"Yes♡♡ Oh, oh, oh, oppa, please cum in my pussy♡ Please fill my pussy♡♡"

"Stretch your legs and arch your back!"

"Please fill my pussy. Oppa♡♡"

Serena lies on the bed, stretching her legs straight, and subtly exposes her plump bottom. I straddle her firm buttocks with my throbbing erection, supporting my weight while I thrust my member inside her.

As if turning a faucet, I intensely writhe within her velvety folds ♡

Vrrrrrrrrrrrrrr♡ Vrrrrrrrrr♡ Vrr♡ Vrr♡

Serena clenches her hips, taking my weight as she gasps hot breaths.

"Oh♡ Ohhh♡♡ Oppa, you're doing so well. Oppa, you're amazing♡"

Ah~~.

Basking in Serena's praise,

I adore grinding against her large, healing buttocks.

I listen comfortably to Serena's enchanting, melodic voice.

"To think I'm releasing so much inside my little sister's pussy… Hehe…♡"

Vrrrr♡ Vrrrrrrrrrr♡ Vrrrrrrrrrrr♡

Serena giggles softly, her feet tapping the bed as if in pure delight.

"Oppa, I'm so proud of you."

Vrrr…. Vrrrrrrr…. Vrr… Vrr...!!

Upon hearing her words, it was a morning filled with passion, as I even managed to create more seed to release into Serena's womb.
