I moved closer to her, lifted her face with two fingers, and looking at her blushing cheeks, I lowered my head and kissed her.
As I kissed her lips deeply, I teased her body with my hands, relentlessly arousing her already high breasts and firm buttocks.
She offered slight resistance, but the lust in her body, and the fact that the one doing the teasing was me, who had always cherished her, weakened her resistance, until she finally gave up.
After giving up, my sister wrapped her arms around my waist and gently caressed my full buttocks, while her tongue began to respond to my deep kisses, her breathing becoming increasingly rapid.
Then she voluntarily took off her clothes, revealing her not-yet-fully-developed body before me.
My younger sister's still somewhat immature body was displayed before me. She shyly said, "Brother...sister, I...I..."
This was the first time my sister had shown her body to me. In her mind, I had always been her good older brother, and now I was going to be her man, leaving her bewildered.
I transformed back into my male body and forcefully pushed her onto the bed.
My sister looked at me, who had just been a tall, beautiful woman, now a handsome man, and didn't know how to react. But I didn't give her time.
After pushing her onto the bed, I rubbed my large penis against her vulva a couple of times, then whispered in her ear, "Good sister, brother's going to fuck you. Enjoy experiencing brother's big cock!"
Hearing my words, my sister suddenly relaxed, her tension instantly vanishing.
When my large penis entered her long-unused cunt, she moaned with pleasure.
Then she hugged me tightly, letting me ride her, thrusting into her long-dormant cunt.
My sister's technique was excellent; it seemed she went wild while she was being a slut. As my penis thrust in and out of her cunt, her hips and buttocks immediately moved in rhythm, responding to my every move.
The sounds of flesh slapping against flesh and her moans of pleasure echoed in her room.
We fucked for nearly three hours. We changed positions from the initial missionary position to her sitting on my lap; then she straddled me; then she lay on the bed while I fucked her from behind; and even she walked to the floor, her hands against the wall, her ass raised, while I fucked her from behind—we tried almost every position we could think of.
During those three hours, I ejaculated inside her five times, while my sister orgasmed more than ten times.
After our final orgasm, my sister collapsed completely into my arms, too exhausted to move.
After the passion subsided, I held my limp sister as we rested.
After my sister regained some strength, I asked, "Are you feeling better?"
My younger sister nodded in my arms.
"Do you like it?"
I asked again.
My sister nodded again.
"Are you happy?" My sister continued to nod. Then I lifted her head from my arms and asked, "Do you like it when you're with Daddy, Uncle, and Uncle Long?"
After hearing my question, my sister shyly buried her head in my arms again and softly answered, "Yes."
Looking at my sister, whose ears were red, I asked curiously, "You like everyone, and you like having sex, so why do you reject everyone? Everyone likes you!"
After hearing this, my sister said shyly, "I want to be a heroine that everyone admires. If others know that I'm a slut who likes big dicks to fuck, then..." My sister didn't finish her sentence, but I already understood.
It seems that my little slut sister wants to be a whore but also wants to maintain a virtuous image.
I burst out laughing when I heard that, and she snuggled into my arms, playfully hitting me and saying how annoying I was.
After playing around with my sister for a while, I said to her, "Silly sister, a heroine admired by everyone isn't a celibate heroine. As long as your actions conform to the spirit of chivalry, people don't care who you fuck! Even if people don't like sluts, you can be slutty in secret! As long as no one knows, even if your little cunt is fucked raw, people will still think you're a virgin! Besides, you're from our Long family. As long as you don't let others gang rape you in public, no one will suspect you. If you're still afraid of being exposed, then just be slutty at home. There are so many good men in the family; they can definitely satisfy my cute little slutty sister."
My sister blushed and looked at me, then said, "I'm just shy! I'm afraid everyone will laugh at me for being a pure heroine outside and a slut at home."
"Silly girl, the family loves you so much, how could they laugh at you? If anyone laughs at you, your brother and dad will deal with them," I said, rubbing her little bottom.
After hearing this, my younger sister pouted and said disdainfully, "If I were to ask someone, it wouldn't be you. Everyone in the family knows you're a two-timing brother! When you're a woman, anyone can play with you and fuck you however they want; when you're a man, your lover plays with your sister-in-law right in front of you, and you kneel down and serve him, even letting him play with your ass. You want to discipline them? You'd be the one getting disciplined, all you do is bully your cute little sister, you bad brother."
I immediately smiled, then transformed back into my female form, hugged my sister's body (which was still somewhat immature to me), and said in a seductive tone, "Oh! You know your older sister is a big slut! It's okay, although I can't teach them a lesson, I can beg them! I'll bare my big ass, shake my big tits, and beg them not to bully my cute little sister. Then I'll tell them, 'You can play with my sister's cunt as you please, and you can play with her asshole as you please.'
If they're not satisfied, there's still me, their older sister, to play with."
"You can do whatever you want with us, but don't tell anyone my dear sister is a little slut who loves being fucked by big dicks!"
"She wants to be a heroine everyone admires!"
"Don't play with our cunts and assholes and then call us sisters sluts who can be fucked at will!"
"What do you say? My dear sister, how about I beg you like this?"
After hearing this, my sister rolled her eyes at me, pinched me hard, and said, "Bad sister, if you say that, then we sisters are both their bitches. I still want to be a heroine!"
Then she angrily ignored me.
I didn't care, and started tickling her waist with both hands. She immediately surrendered and begged for mercy.
After we fooled around for a while, I went back to being a man and fucked her again.
This time she completely let loose, her little ass wiggling wildly and her moans were incredibly bold.
She kept shouting, "Brother, fuck my little cunt hard!"
"My asshole is so itchy! Brother, fuck me harder!"
"Brother's cock is so powerful, I can't take it anymore, I'm going to be fucked to death by you!"
"Good brother, my little cunt feels so good, brother, just keep playing with me! I'll let you play with me for a lifetime!"
This time I ejaculated twice, while my sister had multiple orgasms. By the time I ejaculated the second time, she had already orgasmed seven or eight times.
After the orgasms, we played around for a while.
My sister cursed me, "You perverted brother! Your dick is so amazing, yet you let your sister-in-law play with other men, and even let her lover fuck your ass! You even became a woman, a harlot, and let her be fucked by the lover along with your sister-in-law!"
I chuckled and said, "That's not all! You don't know, do you? Your sister-in-law's pregnant with that lover's child. In a while, she'll be marrying me, her brother, while pregnant with another man's bastard. I'll be marrying a wife pregnant with another man's bastard's child, and I'll be raising that bastard's child for your sister-in-law's lover!"
My sister was shocked, her mouth agape in a wide "O" shape.
Then she pinched me hard, calling me a pervert. After a while, she nestled in my arms.
Then she whispered, "I really envy my sister-in-law, having such a good husband like my brother. I wonder if I'll ever meet a man like him? I really hope I can marry a man like him."
Seeing my sister's slightly forlorn look, I ruffled her hair and said, "My little sister is so cute and pretty, she'll definitely meet a good man. Even if he doesn't like sluts, you can have your sister-in-law and mom get to know him well, and they'll definitely make him like us."
My sister smiled happily after hearing my words, then mischievously said, "And my good 'older sister' has to help too!"
Seeing my sister brighten up again, we played around for a while longer before resting.
