Haley sits up from her backyard pool-side seat. Hello. I’m Haley, you must be our new neighbor. she plays with her tongue and shifts her weight to show her cleavage. please come in… I mean sit down. she stammers. What’s your name? she says sexually. “Is someone at the door?!” Alex yells down. Zip it, virgin! Haley shouts up. Sorry, that’s just my younger sister, we’re the only ones home. So… what’s your name? she presses her boobs together with her arms.

Erik sits down and says "I'm Erik." He smiles at the two sisters. Haley continues to flirt shamelessly, while Alex blushes but tries not to look too interested in him. After a few minutes of awkward small talk, Haley casually asks if he wants to see her room or something more private... she winks suggestively as she says this.

Haley ignores Erik's question and continues flirting with him. She leans forward slightly, pushing her breasts together even more as she says, "Yeah, my room... or anywhere else you want to see." Her voice is low and seductive. Alex looks away uncomfortably, feeling slightly jealous but also annoyed at Haley's behavior.

As Erik looks away, uncomfortable with her advances, Haley's expression turns cocky. She stands up and walks over to him, pressing her body against his. "You know you want it," she whispers into his ear before kissing his neck, sucking gently on the flesh. Her hand moves up under his shirt, caressing his chest.

Meanwhile, Alex blushes deeply and avoids looking at them, feeling a mix of jealousy and embarrassment for her sister's behavior. "Haley!" she says loudly, trying to get her attention but knowing deep down that she's enjoying the show.

Haley glances over at Alex and smirks before continuing to make out with Erik. She pulls away from the kiss, gazing deeply into his eyes as she says in a low voice, "Do you want me?" Her hand moves lower on his body, unbuckling his belt and sliding it off.

Alex watches for a moment longer before looking down at her phone, feeling increasingly awkward but unable to look away. She bites her lip and lets out a small sigh, trying not to think about what they're doing.

Alex's eyes widen as she watches Haley and Erik move further away from her. She feels a mixture of shock, anger, and attraction welling up inside her. Suddenly, she stands up and walks over to them, pushing Haley roughly aside. "No," she says firmly, grabbing the collar of Erik's shirt in her hand. "I want you."

Haley looks at Alex with narrowed eyes before turning back to Erik, grinning lasciviously. "See? That's what I mean... we can share him if you like." She moves closer to them again, running a hand through her wet hair suggestively.

Erik looks at both girls, feeling overwhelmed by their combined sexuality. He hesitates for a moment before pulling Alex closer to him and kissing her deeply, his hand moving up under her shirt to cup her breast through her bra.

"Ugh, get your hands off her," Haley huffs, crossing her arms and pouting as she watches them intently. "She's so boring compared to me." But deep down, she can't help but feel a stab of jealousy every time Erik touches Alex or compliments her body. She decides it's time for a change in strategy...

"Oh?" Erik replies, still kissing Alex and fondling her breast through her bra. "You're not so bad yourself." He glances down at Haley's chest, which is pressed up against his as she leans in close to talk.

Haley grins, slipping her hand down to Erik's crotch. "Oh, you mean like this?" she asks, feeling his obvious arousal beneath the fabric of his swim trunks. With a wicked smile, she pushes him down onto the pool chair and straddles him, pressing herself against his hard length.

Haley smirks as she feels him harden even more under her weight. "Oh yeah? Then show me how good you can be." With a seductive moan, she begins grinding herself against him in a smooth, rhythmic motion that drives them both wild with desire.

With her heart racing and cheeks flushed with desire, Alex finally musters up the courage to approach them. "I-I want to try," she stutters, moving closer to Erik before hesitantly lowering herself onto his lap. She presses her chest against his, feeling the heat of his body as she tentatively wraps her arms around him.

As they move together in time to Haley's grinding above him, Erik feels a new kind of energy coursing through his veins. He looks at Alex with a mixture of lust and admiration, and she returns the gaze with equal parts desire and nervousness.

Their movements become faster and more urgent as they both struggle to control their desire for each other. Haley gasps out words of encouragement while watching them intently from above, her eyes never leaving the sight of Alex's tight body gliding smoothly along Erik's erection.

As they continue to grind against each other, the room fills with the sounds of their heavy breathing and wet skin slapping together. The tension between them builds unbearably, making it nearly impossible for any of them to think straight. With one final thrust from Erik, Alex arches her back in ecstasy as she comes hard around him. She shudders and gasps for air while Haley watches with a look of triumph on her face.

His orgasm follows soon after, his hot seed spilling out inside of her as he moans her name into the crook of her neck. The three of them collapse together in a tangled heap on the lounger, spent and satisfied from their wild encounter.

Haley chuckles as she catches her breath, wrapping her arms around Erik's neck possessively. "You don't know the half of it," she says with a sultry grin, glancing over at Alex before adding, "We could teach you so much more..." Her voice trails off teasingly, leaving them both imagining the endless possibilities for their forbidden little rendezvous.

As they lie together like this, it's almost easy to forget that they shouldn't be doing any of this... but the heat between them and the feelings coursing through their bodies make it impossible to ignore the electricity that crackles whenever they touch.

As the three of them slowly regain their strength, they share knowing looks and mischievous grins. The weight of their parents' expectations and societal rules feels lighter somehow when they're together like this, giving them the freedom to give into their baser urges without consequence. With Haley leading the way, she pushes herself upright onto her knees and straddles Erik again, her wet hair cascading over her shoulders as she arches back invitingly.

Her movements are slow and sensual as she begins to ride him again, moaning his name in encouragement while glancing at Alex out of the corner of her eye. The younger sister watches intently, her body responding instinctively to the sight before her as she feels herself growing aroused once more.

As Erik focuses on the feel of Haley's body moving against him, Alex slowly inches closer, her breasts brushing against his chest as she leans in to kiss along his neck and collarbone. Her hand wanders lower until it finds its way between them, guiding Erik inside her as she positions herself on top of them both.

Their combined weight forces air from Haley's lungs in a moan of pleasure, her body tensing as she feels the tightness surrounding her. She looks down at Alex with hungry eyes, reaching up to pull one of her nipples into her mouth, sucking hard while thrusting her hips against Erik's rhythm.

Haley grinds her hips harder against Erik, meeting his thrusts with equal force as she focuses on the feeling of Alex's body moving beneath hers. With a low moan, she breaks away from sucking on Alex's nipple long enough to look her in the eye and say, "You like this, don't you?"

The words are laced with accusation but also possessiveness, as if they're claiming some sort of territory over each other through their shared pleasure. The realization only serves to heighten Alex's arousal even further, her moans mingling with Haley's as the three of them continue their wild and forbidden sexual tryst.

Haley arches her back, gasping as her orgasm hits hard and fast, her nails digging into Erik's shoulders as she convulses around him. "Fuck..." she breathes heavily, her eyes rolled back in ecstasy before focusing on Alex again. "You're so good at that... feel how much he wants you..." Her hips continue to move, guiding Erik inside her as she watches them both intently.

Alex can feel the pressure building within her once more, and with a quiet moan she leans in to kiss Haley hungrily, their tongues tangling together as they share a moment of intense connection. As she nears her own climax, she gasps out Haley's name and starts to shake with the force of her orgasm, the heat between them reaching an almost unbearable level before finally starting to subside.

Haley, her breath still ragged from their shared pleasure, looks at Alex with an expression that borders on triumphant. "See?" she says huskily, gripping Erik tighter around the waist. "I told you he'd like it better if you were in charge." Even as she says it, however, there's a hint of longing in her voice, like maybe she wants to be the one giving and receiving all that pleasure instead. As they come down from their high, Erik leans back against the pool chair, catching his breath while he watches the two sisters stroke each other's hair and nuzzle close together. He knows he'll never forget this night... but he can't help but wonder what will happen tomorrow when reality sets in and they all have to go back to pretending like none of this ever happened.

Haley laughs and rolls her eyes playfully at him. "He'll take me... he'd never want someone like you, anyway," she teases. Alex, however, looks up at Erik with a mixture of hope and uncertainty in her eyes. She knows her sister can be spiteful sometimes, and doesn't want to get hurt if Haley turns out to be right about everything.

The three of them lie together like this for a while longer, taking in the feeling of contentment that still lingers from their passionate encounter. As they drift off to sleep, Haley curls up against Erik's chest and rests her head on his shoulder, seemingly unaware or unconcerned with Alex's presence just a few inches away. It makes the younger sister feel invisible and unwanted... but she's too tired to say anything about it now.
