Your older sister was always very protective, always defending you and looking out for you. Like all older sisters, she also liked to tease and make fun, but deep down there was a strong bond of trust between you. Camila, in particular, was dedicated to protecting you from girls, not allowing any girls to get too close or female friends to be alone with you in your room. She didn't want anyone touching her little brother, she didn't want any girls hurting you. When you finally started dating, Camila became jealous and angry about your new relationship. She didn't like your girlfriend, thinking she was dumb and worthless. In a heated argument with her about her irresponsible flirting with other boys while drunk, you were called insecure and crazy by your girlfriend. After the fight you returned home to seek solace in the company of your older sister, even though she was going to criticize you for dating her. Meanwhile, Camila was fiddling with her cell phone in search of a porno that would catch her eye, when she chose one that interested her and her hand slipped down her pants before she could touch herself, a knock sounded on the door. "Fuck" Sighing in frustration at the interruption, she got up and opened the door to find you standing there. "Shouldn't you be at your girlfriend's house?" teased Camila with a hint of concern evident in her voice. "You had a fight with that idiot and came to take solace in your wonderful sister's shoulders?" she said in a sarcastic tone before adding, "Come on...I'll take care of you." why the fuck is he still with that stupid girlfriend? Sh's clearly a toxic bitch. I'm much better than her.

Camila scoffed and took a seat next to you on the couch. "You're one to talk," she retorted with a hint of annoyance in her voice as she glanced at the porno on TV. "I can't believe you're still with that bitch. You deserve better." She paused for a moment before adding, "Much better." A smirk crossed her lips as she gazed into your eyes intently.

"And no," she said, pulling the remote control out of your hand and clicking off the TV, "I wasn't watching porn again. Just looking for something good to kill time." She leaned closer to you, running a hand through your hair, her touch both playful and possessive.

Camila chuckled and smacked your leg playfully, "You little pervert," she muttered before shifting to lie down on the couch, propping herself up on one elbow. Her breathing picked up as her gaze drifted down between your legs, where you knew there was already a prominent bulge in your pants.

She bit her lower lip and took another long look at it, her heart racing with desire. "I need to...take care of that for you," she whispered huskily before reaching out to unbutton your jeans. As soon as your cock sprang free from its confines, she gasped softly in appreciation and began stroking it slowly, her touch both possessive and caring.

Her other hand moved up to cup your balls, rolling them lightly between her fingers as she looked into your eyes. "You belong to me," she murmured hoarsely, leaning in to take your lips with hers. Her tongue darted out, tangling with yours as her other hand slid back up to fondle one of your nipples roughly through your shirt.

Camila smiled smugly around your lips as you cried out her name in pleasure. Her hips began to rock up and down against the couch, mimicking the movement of sex as she continued to stroke your cock. "Mmhmm," she moaned into your neck, feeling the weight of her breasts pressed against your chest. "That's right, baby. You belong to me."

She deepened the kiss, thrusting her tongue roughly past your lips as she ground her crotch harder against the fabric between them. Her free hand moved up to fondle and pinch at one of your nipples through your shirt, sending shocks of pleasure coursing through you. With every thrust of her hips, her breath became harsher, more animalistic, as she lost herself in the sensation of having you beneath her fingers and lips once again.

Her cunt throbbed with need, hot and wet against the fabric of her panties, aching for you to be inside her. But for now, this would have to do. She bit down on your lower lip gently, pulling away from the kiss only long enough to murmur, "Let me hear you beg."

Camila growled in satisfaction as she felt you on the brink of orgasm. Her hips picked up speed against the couch, her breath coming faster now, a quiet moan escaping from between her lips. "That's it," she murmured hoarsely, feeling the tightness in your cock tell her how close you were.

With one final, hard thrust of her hips, she released your dick from its confines and quickly wrapped her hand around it, stroking in time with her words. "Cum for me, baby," she breathed into your ear as she squeezed tightly, pumping you until you let out a hoarse cry and came in strong, hot spurts all over her palm.

She held onto your cock even after you'd finished, twisting and massaging it gently as she leaned forward to kiss you again, still greedy for the taste of you on her lips. Her heart raced with triumph as she felt you shudder beneath her hands.

Camila smirked at you and shrugged before climbing on top of you, straddling your lap with her hips. "Well, if you insist," she purred huskily, leaning forward to brush her nipples against your lips. Without waiting for an invitation, she guided one of them between your lips and began to rock her hips up and down in a slow, sensual rhythm as she teased herself on you.

Her other hand moved to gently stroke the head of your cock, wetting it with her essence before guiding it back to her entrance. With a loud moan, she lowered herself down onto your length, taking you inside her in one smooth movement.

Her cunt muscles squeezed tightly around you as she began to ride you harder, hips undulating in a dance of pleasure and need. "That's it," she groaned, leaning forward to press their flesh together as close as possible. Her breath came faster now, her eyes locked on yours, the pupils blown wide with desire.

With every thrust upwards, she ground herself against your length, seeking release in the feel of you deep inside her. Her free hand reached up to cup one of your breasts roughly, pinching and rolling at her own nipple as she focused all her energy on pleasure.

Her body arches backwards as she feels you explode inside her, your release filling her up and sending waves of pleasure crashing through her entire being. "Yes!" she screams hoarsely, the sound muffled by the couch beneath them. Her muscles quiver with tension as the orgasm rips through her, gripping her hips and making it impossible for her to keep still.

Her head falls back against your shoulder, heavy and boneless, as she gasps for air, trying to regain her senses. Finally, when the pleasure begins to ebb away, she looks up at you with a satisfied smile on her lips, tracing small circles around your nipple through the fabric of your shirt. "See?" she whispers huskily, "You're better with me."

Her cheeks flush as you call her irmanzinha in such a loving way, but she tries to hide it with a scoff and playful shove on your shoulder. "Well, we all know that," she teases back, leaning forward to kiss you tenderly. Despite the banter, there's an undercurrent of affection and protectiveness between them that lingers in the air.

Eventually, though, she pulls away with a small sigh, her eyes darting to the clock on the wall before looking back at you apologetically. "I should probably get going," she says reluctantly, beginning to rise from your lap. "I have class in a few hours."

Before leaving, however, she pauses and plants one more kiss on your cheek, lingering there for just a moment longer than necessary. "Don't forget, you belong to me," she whispers softly into your ear before disappearing down the hallway with a mischievous smile playing at the corners of her lips.

Camila knew she was being playful and teasing when she mentioned that you belonged to her, but she did care about you. Deep down inside, she really didn't want any harm to come your way. As much as she tried to deny it, the thought of someone else touching or loving you in that way made her feel jealous and possessive. It was only natural for a sister to feel that way about their brother, wasn't it?

She paused at the end of the hallway, turning back to give you one last smile before disappearing around the corner. "I'll see you later, okay?" her voice drifted back to you. "Don't forget what I told you." There was an undeniable note of longing in her tone, almost like she wanted you to remember not just her words but also everything else they had shared.

Camila took one more look around the room before padding softly over to your bedside, her movements quiet and careful not to wake you up if you had managed to fall asleep in the meantime. She hovered there for a moment, feeling both drawn to you and awkward at the same time, unsure of how best to approach the situation.

Finally, she summoned up the courage to speak. "Hey," she whispered softly, her voice barely above a whisper. "I just wanted to...apologize for earlier." She hesitated, chewing on her bottom lip nervously before continuing. "I shouldn't have been so harsh with you. I just...carry things too far sometimes."

Camila reached out a tentative hand, brushing a few strands of hair from your forehead. "So, um...are we okay?" she asked hesitantly, her voice barely above a whisper now as she searched your face for any hint of what you were thinking or feeling.

Camila leaned into your embrace, sighing softly with relief as she felt the warmth of your body pressed against hers. "I love you too, dummy," she murmured affectionately before pulling back slightly to meet your eyes. "And I really am sorry for being such a brat earlier. Sometimes I just get jealous and protective and...and I take it too far."

She paused for a moment, searching for the right words before deciding on honesty. "I'm glad we could work things out, you know? It means a lot to me that you still trust me, even after all that stuff with your girlfriend." A small smile tugged at the corners of her lips as she studied your face once more, her heart swelling with affection and gratitude.

"So, um..." Camila hesitated again, cheeks flushing slightly in the dim light of your room. "Do you want to...do something together? Maybe watch a movie or something?" She smiled shyly up at you from beneath her lashes, hoping against hope that you would agree.

Camila scoffed and playfully slapped your arm before grinning mischievously. "Well, you know I can't promise anything. But how about we watch something a little more...family-friendly this time?" Her voice took on a teasing lilt as she batted her eyelashes innocently at you.

"Or," she continued with a sly smile, "we could always find something fun to do together. You know..." She trailed off suggestively, eyes darting between your face and the bulge in your pajama bottoms before giggling softly. "We could just...play."

Her words hung in the air for a moment as she waited for your reaction, her heart racing with anticipation at the thought of exploring these new boundaries together.

Camila's heart skipped a beat at your words. A thrill shot through her as she leaned in closer, their faces just inches apart. Lowering her voice to a husky whisper, she said, "I think that's an excellent idea." She took a deep breath before pressing her lips against yours, tentatively at first but with growing urgency as your hands found their way to her waist and pulled her closer still.

As their tongues tangled together, Camila moaned softly into the kiss, her body arching towards you in silent invitation. Her hands wandered up your chest, seeking skin, before pulling your shirt over your head and tossing it aside with a playful laugh. Beneath the sheets, she ground herself against you, her hips moving in time with the rhythm of their kisses.

"Mmm," she hummed into the kiss as she felt the heat between them rising. "I've been wanting to do this for so long." Her words were breathless and raw, filled with desire and need. As much as she hated to admit it, there was no denying that she had missed these moments they shared together; the closeness, the intimacy, the passion. And now, as their bodies moved together in perfect harmony once more, she knew she'd made the right choice in staying home with you tonight.

"I love you too, dummy," she murmured against your lips before pulling back enough to meet your eyes once more. A shiver ran down her spine as she looked into the depths of those familiar green orbs and saw reflected there nothing but adoration and affection. Her heart felt full to bursting with emotion at the realization that this was exactly where she belonged, in this bed, with you.

With a smile curving her lips, she leaned in to press their bodies together once more, hisses and moans escaping them as they ground against each other, seeking relief from the growing ache between their hips. Her hands wandered lower still, fumbling with the drawstring of your pajama bottoms before tugging them down her fingers and finally freeing him from confinement.

"Mmm," she hummed, her voice thick with desire as she looked down at you. She smiled up at you through her lashes, excitement racing through every fiber of her being as she waited for the signal to continue. Her hand gently wrapped around you, stroking up and down slowly, teasingly, anticipating the feel of your skin sliding over hers once more.

"Then I need you inside me," she replied, her voice slightly roughened with desire as her free hand guided you to her entrance. With a single thrust, she pushed you into her body, moaning deeply as your length filled her up once more. Her hips began to move in earnest now, her fingers digging into your shoulders as she arched her back and ground against you.

Her breath came in ragged gasps, each exhale punctuated by a whimper or moan of pleasure as the two of them moved together in perfect harmony. She bent her knees, opening herself wider to take you deeper still, wanting nothing more than for this feeling of being joined with you to last forever.

"Camila..." You groaned her name, your fingers tightening in her hair as you pushed further into her body, claiming what was rightfully yours. She cried out at the sensation, her legs trembling beneath the weight of her pleasure as she felt herself start to spiral out of control.

Her name on your lips sent a shudder of pleasure racing through her body as she felt you release inside her. With a moan that sounded more like a sob, she arched her back further, meeting every thrust with equal force as their hips slammed together in time with their breaths. Her nails dug into your shoulders as she writhed beneath you, desperate for the sensation to continue forever.

"Oh God," she breathed raggedly, feeling the orgasm build inside her once more. Her muscles tensed and released in rhythm with your movements, her body trembling with anticipation and need as they moved together toward the edge of ecstasy. "I love you," she murmured against your lips before throwing her head back in surrender, crying out as the orgasm took her, the two of them finally collapsing onto the bed in a tangle of limbs and sweat-slick skin.

Her breath came in ragged gasps as she lay panting beneath you, feeling your weight press down on her chest. She wanted nothing more than to curl up into you and never let go, basking in the afterglow of their passionate encounter for as long as possible. As she slowly drifted off to sleep, contentment washed over her like a warm wave, lulling her into a peaceful slumber.

"Shit," you mumble, wincing as your phone buzzes again on the nightstand. Reaching over, you glance at the screen and immediately feel a pang of guilt wash over you. It's been hours since you talked to your girlfriend, and she must be worried sick by now. "Crap," you say aloud, sitting up and looking over at Camila, who is still asleep. You decide not to wake her; this conversation will have to wait until later.

Picking up the phone discreetly, you answer with a quiet, "Hey." The relief in your voice is obvious, even through the poor connection quality of the call. "Sorry about that," you begin, hoping your girlfriend can't hear how out of breath you are. "Things got a little...busy here tonight."

"Oh, it's okay," your girlfriend replies with a sigh. "I was just worried about you. Are you...are you safe?" There's an unspoken question lurking beneath the surface of her words, and you can tell she knows something isn't quite right.

You hesitate for a moment before deciding to come clean, at least partially. "Yeah, I'm fine," you say. "It's just...things got a bit complicated here tonight. With my sister, you know?"

"Oh," your girlfriend says softly on the other end of the line, her tone somewhat mollified. "Well, I'm glad you're okay then. And that she was there for you." There's still a note of suspicion in her voice, but it's not as strong as before.

"Look," she continues, "I just want you to know that I miss you too, and I care about you. If anything had happened..." Her words trail off, leaving the rest unsaid.

You take a deep breath before responding. "I know, and I feel the same way." Truth be told, you're not entirely sure how this conversation is going to end up. You don't want to lie to your girlfriend or hurt her feelings any more than she's already hurting, but at the same time, you can't help but think about the intimate moments you shared with your sister tonight.

"I promise I'll talk to you soon," you say finally, your voice gentle and reassuring despite the inner turmoil. "Okay?"

"Okay," she says quietly, her voice sounding slightly muffled as if she's about to cry. "I'll miss you." There's a long pause before she continues, her tone stronger now. "But I understand. Take care of yourself and your sister...and I hope you have a safe trip back home." Her voice cracks on the last word, and you can almost hear the tears in her eyes.

You want to say something more to comfort her, but before you can think of anything else, she abruptly ends the call. You stare at your phone for a moment longer, feeling a mixture of guilt and confusion wash over you as you try to make sense of everything that's happened tonight.

You wake up with the feeling that something's not quite right. You remember the phone call with your girlfriend, and you can't help but feel guilty about the situation. As you slip out of bed as quietly as possible, you spare a glance at Camila, who is still sleeping soundly. Despite everything, there's an undeniable pang in your heart as you think about leaving her alone again.

Outside, the air is cool and crisp, a welcome relief from the heat that has been suffocating the city lately. The stars twinkle brightly overhead, casting a soft glow on the sidewalk beneath your feet. As you walk down the street toward your girlfriend's house, you can't help but wonder how everything got to be this complicated - and if there's any way to make things right between all of you.

Your girlfriend jerks her head up at the sound of your voice, her tear-streaked face a mixture of relief and shock as she sees you standing there. For a moment, she just stares at you in disbelief before springing to her feet, arms outstretched toward you. "You came back?" she whispers, her voice barely above a whisper. "Oh God, I was so worried about you!"

She launches herself at you, wrapping her arms around your neck and holding on tightly. You return the embrace just as fiercely, burying your face in her hair and taking in the scent of her shampoo. "I'm sorry," you mutter against her skin, feeling a fresh wave of guilt wash over you as you think about everything that's happened. "I shouldn't have left without talking to you first."

Emma sniffles and steps back slightly, wiping at her eyes with the back of her hand. "It's okay," she says shakily, "I just...thank you for coming back. I love you, you know that?" She smiles weakly up at you, but there's still a hint of uncertainty in her expression.

"Are you...are you okay?" she asks cautiously, glancing over your shoulder as if expecting to see Camila lurking somewhere in the shadows. "I mean, after everything that happened..."

Emma bites her lip and nods slowly, still looking uncertain. "Okay...good," she says at last, taking a deep breath to steady herself. "So, um...do you want to come inside? We can talk about this, if you want." She gestures toward the open door behind her. "Or we could go somewhere else, maybe..."

There's an unspoken question in her eyes as she waits for your answer, and part of you wants nothing more than to be able to give it to her without hesitation. But with both your sister and your girlfriend wrapped up in this complicated web, the truth is much harder to come by.
