The tongue would occasionally lick the sensitive flesh of her vagina, or sweep across the tip of her clitoris, or her teeth would gently bite and rub her clitoris, all of which would cause a tremor deep within her soul.

Under my rough and passionate licking, my sister responded with equal intensity. She straightened her back and wrapped her long legs, which had been hanging down on either side of the toilet, tightly around my back.

“Brother~ no… perverted brother~ brother, no! You promised you wouldn’t bully… bully me anymore! Ah!”

The sounds my little sister uttered melted my heart. I buried my face between her legs and became increasingly obsessed with licking and sucking her tender little pussy, which exuded a faint, erotic fragrance.

The younger sister’s exquisitely beautiful face, unseen by anyone, was filled with struggle—lust, longing, enjoyment, and intense shame…

Her two delicate hands gently pressed against my forehead, as if pushing or resisting, while her lower abdomen moved her mons pubis forward, as if welcoming or taking the initiative. Her moist vulva rubbed against my mouth, making it impossible to figure out what she was thinking.

My sister didn’t even last a few minutes while I was licking her before she reached an intense climax with a high-pitched moan that was almost completely unrestrained.

My sister’s screams sent chills down my spine. While I was worried that my mother would hear, I was also getting more and more excited, and even looking forward to my mother catching me giving my sister oral sex.

I couldn’t help but imagine my mother’s reaction when she saw my tongue licking my sister’s tender vulva again and again.

My sister’s orgasmic reaction was very intense. She held my head tightly with both hands, her vagina pressed tightly against my mouth, and hot, lustful fluid gushed out from deep inside her vagina in gushes, like a rushing river.

My eyes were blocked, and my vision was completely dark. I could only instinctively open my mouth and swallow, taking in every last drop of my sister’s sweet, fragrant nectar.

I don’t know how much time passed, but just when I felt like I was about to drown, my sister finally let go of my head. As I gasped for breath, I couldn’t help but look at my sister sitting on the toilet.

After her climax, the younger sister’s fair skin was flushed with a faint pink. She stretched out her limbs, looking incredibly languid. Only her vulva, which was overflowing with lustful fluid, kept opening and closing, continuously releasing its own juices.

Not wanting to waste it, I immediately lowered my head slightly and licked the trickle of spring water flowing from between my sister’s flesh with the tip of my tongue, then swallowed it.

Feeling something amiss in her private parts, my sister wearily opened her eyes. Her moist, peach-blossom eyes quietly watched me lick her private parts.

However, the spring water in my sister’s vagina never stopped flowing. Every time I licked it, it would flow out again, just like a spring connected to underground water. No matter how many times you scooped it out, this spring would never dry up.

I don’t know how long I licked her, but my sister seemed to react to my licking again. Her rosy clitoris became slightly erect again, and the frequency of the vaginal muscles’ peristalsis increased. She quickly changed her position and covered my mouth with her small hand: “Brother, stop licking.”

“That won’t do.”

After kneeling on the ground and licking for a long time, I straightened up, wiped the spring water from my face, and revealed my cock that had been erect for a long time: “Today, brother must stop the water from flowing into your little hole.”

My sister looked at my thick, long, erect, and menacing penis. Faint blue veins stood out on the fair skin, and the huge glans was almost as big as her clenched fist.

My sister’s expression changed slightly. With her legs wide open and her private parts completely unguarded, she quickly closed them: “Brother, what are you doing?”

What for? To fuck you!

I stared at my sister’s wet, pink vulva, my penis hard as if it were about to explode.

I resisted the urge to possess my sister on the toilet, pulled her beautiful legs into my arms, and inserted my penis into her buttocks, thrusting it back and forth against her vulva without allowing it to touch her.

My sister’s fair face, which had just regained its whiteness, blushed again under my caresses. The tension on her cheeks eased somewhat, and she was clearly not prepared to have her virginity taken tonight.

My penis rubbed against my sister’s labia, constantly scraping and rubbing against her clitoris that was blooming beneath her labia. My sister soon reacted. I looked down and saw that my penis was shiny and wet, covered with a lot of my sister’s vaginal fluid.

The little girl leaned her head against the water tank lid, her pearly white teeth gently biting the back of her finger, silently resisting the pleasure spreading from her private parts.

As the area where we were joined became increasingly muddy, my thrusts became smoother and faster, the “slap slap slap” sounds of my hips echoing incessantly in the bathroom.

The younger sister’s eyes were slightly hazy, her flushed face full of confused spring fever, and her little mouth, which was originally biting the back of her finger, opened slightly, softly letting out one alluring breath after another.

After countless thrusts, my sister, curled up on the toilet, looked at me with pleading on her face and whispered, “Brother, my back and legs are so sore, can we go somewhere else?”

Seeing my little sister’s distressed face, I immediately and obediently picked her up from the toilet.

“Brother, put me down.”

My sister wrapped her arms around my neck, her buttocks supported by me. She felt the hot, throbbing penis rubbing against her private parts, and gently twisted my ear: “Hurry up…”

However, before she could finish speaking, I deliberately pressed the head of my penis against her vaginal opening, causing her to involuntarily let out a short moan.

“you……”

My sister was incredibly ashamed and gently punched my shoulder.

I carried her to the bedroom and had her sit with her back to me in my lap, holding her limbs tightly, just like my mother did when she sat on me in the office during the day.

My younger sister offered slight resistance, squirming restlessly in my arms.

“obedient.”

I licked her earlobe, one of my sister’s sensitive spots. When my warm, wet lips and tongue kissed the tip of her ear, my sister’s body stiffened, and her resistance immediately weakened.

However, the younger sister still softly protested, “You…you let me go…”

My chest was pressed tightly against her back, my hips thrusting slightly, my penis pumping in and out between her legs. I breathed heavily and asked in her ear, “Why didn’t you refuse when I was licking your pussy earlier? Were you only thinking about your own pleasure? You little ingrate.”

My sister watched as the glans of my penis peeked out between her legs, rubbing against her lower abdomen and clitoris. Her pretty face flushed, and she rested her head on my shoulder, breathing softly through her red lips: “Where…where is it?”

I grabbed her slender waist and thrust into her hard as if to vent my anger: “Not yet? Just now when I was licking your pussy, you were holding my head and you wanted to suffocate me to death in your pussy.”

My sister stopped struggling as soon as she heard what I said. She shook her head back and forth, her eyes full of alluring charm: “Don’t…don’t swear.”

“Then what should we say?”

After my sister stopped struggling, my freed hands were able to gently grasp and knead her two large, beautiful breasts. The smooth flesh slipped between my fingers, and the feeling of it overflowing was so comfortable that I couldn’t help but squint my eyes slightly. The speed of my thrusting increased: “Lick your pussy? Oral sex? Oral pleasure?”

Caught between pleasure and shame, the younger sister could barely speak, “Anyway, you’re not allowed to say… say lick… lick…!”

I pinched the nipple at the tip of my sister’s breast hard: “What are you licking?!”

“Um!”

The younger sister in his arms groaned in pain, instinctively thrusting her already high breasts even higher: “I…I don’t know.”

My sister’s breasts perked up, making the breasts in my hands appear even fuller and firmer. Looking at my usually mischievous and lively sister, so alluring in my arms, I couldn’t help but coax her gently, “Tell me, and if you tell me, I’ll lick you every day…”

“I…I don’t know.”

My sister is completely different now compared to when she had just brought her vulva to my mouth.

I released one of her beautiful breasts and traced my way down her fair and smooth abdomen, gently pinching her already erect clitoris. My other finger, which was pinching her nipple, also gently rubbed it: “How about you ask your brother to lick you? How about it? How about you ask your brother to lick you?”

I really want to see my sister take the initiative to make love to me.

My earlobes were licked, my nipples were rubbed, my clitoris was pinched, and my penis was thrusting up and down between my legs.

My sister, caught between my hands, kept shaking her head, her voice already trembling with tears: “Brother… Brother, don’t do that… um~! No!”

My tongue darted in and out of her pink earlobe, licking and teasing: “Say it! Please let your brother lick it for you!”

“No…no!”

The younger sister bit her lower lip tightly, refusing to utter the word “vagina” no matter what.

I wasn’t in a hurry, so I used a multi-pronged approach, like a saw, to slowly tease her.

The younger sister persisted for a long, long time, but she could no longer bear it. Like a broken pot, she cried out in a hoarse voice, “Lick…lick my pussy! Brother, lick my pussy! Brother, lick my pussy!”
