Shiori and Chika, though sisters and blood relatives, had entered into a forbidden romantic relationship.

"Big sister...♡"

"Chika...♡"

Shiori lay on the bed, seemingly pinned down by Chika. The two, both in their underwear, gazed at each other with passionate eyes.

"Mmm, mmm...♡ Mmm, haa...♡"

"Mmm, mmm...♡ Mmm, mmm...♡"

Their faces flushed, they looked at each other with burning intensity. Shiori and Chika kissed repeatedly. With each exchange, they passionately intertwined their tongues as if to confirm their feelings for each other, licking and mixing their saliva. Their emotions and excitement grew stronger and stronger.

"Big sister...♡"

"Ah...♡ Chika..."

After several kisses, Chika slowly reached out and stroked Shiori’s stomach. As Shiori trembled at the touch, Chika looked at her with an intense gaze and began to speak.

"Is it okay...? ♡ Big sister... ♡"

"Ah... yes... ♡ You can do whatever you like, Chika... ♡"

Shiori nodded shyly and gently relaxed her body. Seeing this, Chika smiled happily and began to stroke Shiori’s body.

"Thank you, big sister...♡ Mmm, mmm... Big sister’s body... Big sister...♡ Big sister...♡"

"Mmm...♡ Mmm, uhh...♡ Mmm, haa...♡ Ah, mmm...♡"

She stroked Shiori’s belly, traced the curve of her waist, caressed the base of her legs, ran her hand down her thighs, stroked her stomach again, and touched her collarbone and upper arms. Chika moved her hand slowly, as if confirming the smooth texture of Shiori’s skin. Shiori moaned sweetly in response.

"Haa, haaa... Big sister...♡ I’m coming too...♡"

"Ah...♡ Ah, ah...♡ Ah, mmm... mmm, haa... haa, aaaah...♡"

After stroking for a while, Chika gently reached out and touched Shiori’s chest.

"Big sister’s boobs...♡ They’re so soft...♡ Ah, ah...♡ ...Big sister, I’m going to take off your bra...♡"

"Ah, ah, ahh...♡ Ah, eh, ehh...♡ Ah, hya, mmm...♡ Mmm, ah, ahhh...♡"

She gently grasped Shiori’s breasts from below, lightly kneaded them to confirm their soft elasticity, and then removed the bra. Chika then began to rub Shiori’s nipples directly.

"Boobs...♡ Big sister’s boobs...♡ Ah, haa, mm...♡ Mmm, mm...♡ Mmm, mm...♡"

"C-Chika...♡ Ah, ahn...♡ Mmm, haa... Ah, ah, ahn...♡ Mmm, ah, ahn...♡"

While kneading one of Shiori’s breasts with her hand, shaking it and savoring the feeling, Chika brought her mouth to the other breast and took the nipple into her mouth, sucking with a slurping sound. Receiving the sensations of kneading and sucking from her chest, Shiori closed her eyes and moaned softly.

"Mmm, haa...♡ Big sister’s breasts... so soft, so nice to knead, and so delicious ♡... Big sister’s body...♡ Mmm, mmm...♡ Mmm, haaa...♡ Mmm, haa♡"

"Ah, mmm ♡ Ah, hya... ♡ Here, mm, yeah... ♡"

After thoroughly and carefully enjoying Shiori’s breasts, Chika gently removed her mouth from the nipple. She extended her tongue and licked away the bridge of saliva between her lips and Shiori’s nipple, then smiled. Next, she began licking Shiori’s stomach area.

"Big sister’s tummy...♡ Big sister’s belly button...♡ Mmm, haa...♡ Mmm, haa...♡ Mmm, haa...♡"

"Ah, mmm...♡ Mmm, haa...♡ Hyau ♡ Uhyaa, hyah...♡ Mmm, yeah, ahn...♡ Yeah, mmm, aaah...♡"

Chika licked from below Shiori’s chest down to her stomach, then licked around her belly button with her tongue. A tingling sensation spread from her navel, and Shiori gripped the bedsheet tightly with her hands, writhing and trembling from the feeling.

"Ahhh...♡ Big sister...♡ Big sister’s... important place...♡"

"Haa, haaa...♡ Ah, ah...♡ Hya, ahh...♡ Chi, Chika...♡"

After licking her belly button, Chika’s gaze shifted to Shiori’s crotch—to the pussy hidden beneath her panties. Shiori looked embarrassed when she realized that Chika’s hot, excited gaze was fixed on her most intimate area.

"Big sister... I’m coming over here too...♡ ...I’m going to take off your panties...♡"

"Ah... uh, uhh...♡"

Seeing Shiori’s expression, Chika also looked embarrassed and somewhat nervous. She reached for Shiori’s panties and slowly pulled them off.

"Ahhh...♡"

As a result, Shiori’s most important female part—her vagina—was exposed.

"...Haa, haa...♡ Big sister’s pussy...♡"

"Oh, oh...♡"

Seeing the beautiful pink pussy, Chika’s face flushed with excitement. She slowly leaned closer, touched her lips to it, and kissed it.

"Mmm, mmm...♡ I even kissed my big sister’s pussy...♡ Mmm, mmm ♡ Mmm, mmm, mmm...♡"

"Mm, ah, aah...♡"

She took her lips away from Shiori’s pussy, then licked her own lips with her tongue, confirming the taste of Shiori’s pussy once again. Chika’s cheeks flushed with excitement. She kissed Shiori’s pussy again, extending her tongue and beginning to lick.

"Mmm, mmm...♡ Mmm, mmm ♡ Mmm, mmm, haaa...♡ Mmm, haaa...♡ Ahh, mmm...♡"

"Ah, ah...♡ Mmm, ah, ah, ah...!♡ Ah, mmm...♡ Mmm, mmm...!♡ Ah, mmm, ah, aaah...!♡"

While licking her pussy with her tongue, Chika gently licked the clitoris, slowly savoring the sensation as she teased and stimulated it. Shiori cried out as she felt the sweet sensations coming from her pussy, and the volume of her moans increased.

"Ah, ah...!♡ Chi, Chika... I, I’m already... mm, ah, mm, mmm...!!♡"

"Mmm, haaa...♡ Mmm, ah, ah...♡ Mmm, hehe... Big sister...♡"

The stimulation of having her clitoris licked was the final blow. Shiori had an orgasm. Seeing this, Chika stopped licking and smiled.

"Big sister, you felt so good that you came...♡ Let’s feel even better together...♡"

"Ahhh, ha, aaah...♡ Mmm, yes...♡ That’s right...♡"

Chika spoke with an excited, flushed face. Shiori, her body still trembling from the aftershocks of her orgasm, slowly nodded in return.
