Sister XXX

Sam and Tammy emerged from the bathroom with satisfied smiles while pretending nothing was happening. Right in the doorway stood an angry young woman with features similar to Sam's, but smaller.

"Damn, Sam, I told you again..."

"Lower your voice, sister, they can hear you," Sam said calmly.

"Grrr... it's okay, we'll talk about it at home."

Sam said goodbye to Tammy with a small wink and a mischievous smile. Once home, the sisters continued their pending discussion.

"Come on, Sindy, it was nothing," Sam said calmly.

"NOTHING, NOTHING, Sam, I've told you a hundred times: STOP FUCKING MY GIRLFRIEND!"

A malicious laugh took hold of Sam, as if it were a game, one she knew exactly how to play.

"Ha, ha, ha, ha, please, that was so funny."

In response, Sindy's face filled with rage.

"You know what would happen if everyone knew your little secret? It would ruin your precious reputation. IT WOULD GO TO HELL IN AN INSTANT, YOU BITCH," Sindy said angrily.

Sam didn't flinch at her sister's threats and continued laughing even harder.

“Ha, ha, ha, ha, ha, Sindy, first of all, I didn't do anything to your so-called girlfriend that she didn't want. In fact, the ‘bitch’ wanted it,” Sam said, nimbly standing a few inches away from Sindy. “And secondly, if she reveals my secret, yours will be revealed too,” Sam added in a seductive voice.

All of Sindy's anger and confidence vanished, replaced by a great fear. Sam's eyes were fixed firmly on her forehead, colliding with hers. The mere presence of her older sister was enough to turn her into a scared little mouse, but beyond that, there was something else: much to her chagrin, her pussy was starting to drip from its opening.

“That… mmm… that was different… you abused me,” Sindy said, looking down at the floor.

Sam closed the gap even further; their chests now fighting like water balloons.

“Mmm…yes, the first time I was in Celote, I took you as much as I wanted, but the little I remember is you moaning like a damned thing, begging for more.”

Now Sam began to rub herself, rubbing her breasts all over Sindy’s body, which was already trembling like jelly.

“And…then the next night you came to my bed to continue doing things to me,” Sam said, rubbing herself faster.

“But…but…I…”

“And the next night, and the next, the whole damn week, you became my sex doll.”

Sam could feel it. Her legs were wobbly, her breath was coming in gasps, and her nipples had shot out like darts. In short, Sindy's will was now clay in her hands.

“Hm…Sam…let me,” Sindy moaned.

“Mmm, I don't think so. Do you know why? The truth is, you're just jealous that I'm not the one devouring your pussy?”

“Mmm…no…”

“That's right.”

Sam slipped her hand inside her clothes and pressed hard on her left nipple.

“SAAAAAM…AAAAAAAAAAAA”

“Admit it, sister. Deep down, you're even more of a slut than Tammy.”

Sam now reached in with his other hand to attack both nipples.

“OOOOOH SHIT!”

“ADMIT IT, YOU'RE CRAZY FOR THIS, BEING MY PERSONAL TOY.”

With all her strength, she pulled on her nipples, eliciting an orgasm from Sam.

“GRRRRRRR…..I ADMIT IT….NNMMMM

I WANT YOU TO FUCK ME, I'M YOURS TOO…AHHHH”

“And that's how it will be, sis. Now let's have some time together.”

Following that, they both stripped off their clothes to thoroughly explore each other's bodies. In a matter of seconds, they were completely naked on the floor.

“Hey, now, Sindy, I want to hear you sing,” Sam said anxiously.

Without hesitation, she buried her face inside her sister's pussy.

“AAAAAAAAAH…. SAMMMMM”

Sindy was just a puppet at Sam's mercy, whose skillful tongue touched every pleasure button in her cave. Now powerless to stop her, she could only close her eyes and tremble at her imminent release.

“OOOOOH…SAM….. I'M…I'M…AAAAAYYY…YES…YES…YESSSSSSS”

Sindy's screams of pleasure reached every corner of the house. Sam was grateful her mother wasn't home; otherwise, she would have been scared, though not surprised, because she had seen them in similar situations before.

Sam paused for a moment to contemplate her sister. After two orgasms, she was almost conscious, her body suffering small spasms. She loved seeing her so helpless and horny; it filled her with power. She couldn't stop now, as she wanted to expand her hegemony over everything.

“Come to my room. We'll play better there,” Sam whispered in Sindy's ear.

“Mmm….okay,” was all a defeated Sindy said.
