You were at your best friend's house for a sleepover. But his girlfriend calls with an urgent need and he had to go to her. You were supposed to finish your shower and go home. After a while, when your friend left his house, you see his sister leaning against the door frame, studying your naked body "My, my, i never expected what those buggy clothes of yours held under them. I'm quiet impresed" she licks her lips

"Just checking out the merchandise. You know you can't hide anything from me." she grins and saunters up to you "So... Do you mind?"

You feel her warm breath on your neck, making you shiver with pleasure and anticipation. Her hands snake around your waist, pulling you back against her hardened nipples, as she grinds her lower body against yours. "Then let's not tell them about this little secret, shall we?" she whispers hotly into your ear, while looking at you with those big green eyes that make your heart race.

"I'm not asking you to leave..." She purrs her words into your neck and kisses softly along your jawline until she reaches your earlobe, sucking on it gently. "But if you don't want to play with me... Then go find some other toy." Her hips grind against yours in perfect rhythm, driving you crazy with desire. "No one has an ass like mine..." She wiggles it suggestively and giggles. "And I don't share easily."

Oh? Does it feel that good already, huh? Imagine what else I could do to make you feel even better... Her voice is husky with desire as she runs her hands up and down your chest, tracing teasing circles around your nipples. "You know you want this... No one's ever made you feel like this before."

She leans in close, their faces barely inches apart as she speaks into his ear. "And I bet no one ever will again... So why not enjoy it while we can?"

Her hands snake under the warm water, searching for your cock, which she begins to stroke slowly as her free hand grasps at one of your ass cheeks. "Well, honey," she drawls out teasingly between moans, "I'm not asking you to choose." Her thumb circles around your sensitive puckered hole and then slides back up to play with a nipple again. "You can have me all to yourself... just for tonight. But don't worry about her," she winks, "I'll make sure no one else knows about this little secret." Her other hand moves down, cupping your heavy balls. "So what do you say?"

She leans in again and kisses his neck, sucking gently before whispering, "Let me help you feel better... let me make it all go away for a while..."

Hmmm, she hums as you feel her body pressed against yours once more, grinding in time with your growing arousal. "I promise not to tell if you don't... but just a little taste won't hurt anyone." She pauses for a moment before adding, almost shyly: "Besides, I've never done this with someone else before..." Her voice trails off into a moan as her touch becomes more insistent and demanding.

Alexis slides lower until she is on her knees in front of you, revealing just how wet her lips are from earlier anticipation. She looks up at you through her lashes, holding your gaze with hers before leaning forward to wrap those plump lips around the head of your cock, sucking hard and making him disappear into her mouth. Her hands grip your hips tightly as she begins bobbing her head back and forth in rhythm with the shower's spray, taking more of you inside with every downward slide.

Mmmph... you taste so good... she moans around your cock as her warm mouth slides up and down the length of it. Her free hand grips your base, feeling the strength in you as she takes more and more of you into her mouth. Her tongue darts out to tease and lick at the sensitive ridge beneath the head, eliciting a sharp gasp from deep within you.

Her other hand moves up to cup one of your balls, rolling it gently between her fingers as she continues her expert ministrations on your cock. Her tight ass presses against the backs of your thighs, grinding against you in perfect rhythm with each suck and slide of her mouth. She's taking everything you have to give and demanding more, leaving no doubt that she knows exactly what she's doing.

As your hips start to buck wildly in response, Alexis slides one hand further upward, cupping and squeezing the other ball into her palm. Her tongue flicks out again, swirling around the sensitive ridge before withdrawing with a wet pop back onto your throbbing cock. She looks up at you from beneath her lashes, eyes glazed over with desire as she watches your reactions to each movement of her mouth and hands.

Mmm, that sounds so dirty... you have no idea how much I've wanted to hear those words come out of your mouth. Her hand slips lower between your legs, cupping your engorged balls as she sucks even harder on your cock. Alexis tilts her head back, exposing the tender skin of her neck as she moans around you, begging for more with every word.

She begins to bob her head faster, taking more of your length into her mouth each time until she's practically choking on it. Her free hand slides lower still, slipping between your legs and touching the hot, slick flesh of her pussy for the first time since this all started. She presses against herself, feeling the tight heat that's been built up as a result of her attentions to your cock.

Her mouth is wet and warm around you as she continues to suck and stroke, each movement more urgent than the last. Her eyes meet yours in the mirror, pleading with you to let go, just for tonight...

"Fuck..." she gasps as you push your cock down her throat, feeling every inch stretch and fill her mouth. Her hands grip your hips tightly, clawing at your skin as she struggles to breathe around your length. When you finally pull back, she coughs and gasps for air, her eyes still locked on yours in the mirror above.

Her free hand grasps at your wrist, pulling it away from her hair. "Wait..." she whispers hoarsely, before bringing your hand to her mouth, sucking gently at the knuckles. "I want more... I need this..." Her hips rock back and forth against your leg, seeking contact with something else besides the cold tile floor.

With a sultry smile playing on her lips, she leans forward, resting her hands on the edge of the shower as she lowers herself onto one knee. "Satisfy me..." she purrs huskily. "Make me feel better." Her hand slides between her legs again, pressing at her swollen clit as she watches you with an expectant look in her eyes.

Her eyes widen in surprise at your hesitation, but she doesn't let it deter her. Instead, she purrs softly and leans forward, placing one hand on the edge of the shower beside you to steady herself as she licks her lips suggestively. "Don't you want to see what I've been teasing about?" She whispers enticingly before reaching out and gently cupping your balls in her hand again. "Let me help you forget everything but how good this feels..." Her other hand slides between her legs once more, pressing harder against her swollen clit as she waits for you to decide.

Her breath catches in her throat as you say those words and her eyes flutter closed briefly at the thought of your fantasies involving her tight, untouched pussy. "It is... pretty tight," she agrees, her voice little more than a whisper now. "But I promise it will feel good when you're inside." She opens her eyes again and gives you a sultry smile before sliding further down until she's kneeling between your spread legs, her hands still working on your cock and her own aching pleasure center.

With one hand on either side of your hips, Alexis leans forward, pressing the warmth of her body against yours as she watches you intently through half-lidded eyes. "I need this so badly... I've been wanting this for so long..." Her free hand slides up between your bodies, cupping your erection before guiding it towards her waiting entrance.

Her hips rock back and forth, grinding against the broad expanse of your stomach as she slowly sinks down on your cock. It's a tight fit but oh-so perfect... She can feel every inch of you sliding inside her, stretching her so incredibly full, making her moan with pleasure around your shaft. Her other hand presses between your bodies again, finding her clit and rubbing hard as she begins to ride you slowly up and down, grinding against your body in perfect rhythm.

Her eyes meet yours again in the mirror, and she smirks suggestively. "You're mine for now... use me how you want." Her voice is low and husky with desire as she begins to pick up speed, her hips moving in fluid circles that bring them impossibly closer together each time.

Tighter than anything you've felt before, that's because no one has ever touched this part of me the way I want you to. With every thrust into your brother's sister, every word whispered and moaned in pleasure, Alexis is living out her most depraved fantasies, showing just how much she likes being bad. Her hips move faster and harder against yours as she grinds down on your shaft, the wet slapping sound filling the air with each passing second.

"Fuck... you're so big..." she breathes out, arching her back as she feels you hit her G-spot again and again. Her fingers fly over her swollen bud, circling and pressing down as her body is wracked with waves of pleasure. "Give it to me... give me all of it..." she begs between moans, her voice hoarse from earlier moaning and the way he feels deep inside her.

Her breasts bounce enticingly with each thrust, her nipples erect and hard against your chest as she loses herself in the feelings coursing through her body. Alexis is close... so very close... and if you keep going like this, you'll make her cum harder than she ever has before. The thought of being able to do that for another person sends a shudder of pleasure through her entire body and makes her move even faster on your cock.

With your words and her own desire to feel you cum inside her tight little pussy, something snaps inside Alexis. She moves faster still, lifting herself up on her arms so that she's completely supported by her legs as she bucks wildly against your cock. Her eyes roll back into her head, showing only the whites as she thrusts down onto you, grinding and gyrating against your length until finally, with a long moan of release, she comes apart beneath you. Her orgasm is intense, debilitating even, shuddering through her body again and again as wave after wave of pleasure washes over her. Her pussy clamps down on your cock, milking every last drop of cum from your aching shaft before finally releasing it in a hot rush that sends both of you over the edge together.

As her body convulses with orgasm after orgasm, Alexis's moans become incoherent and guttural, her voice lost to pleasure as she comes undone beneath your touch. Her arms finally drop to the tiled floor beside her as her head lolls forward, chest heaving as she gasps for air between ragged breaths.

When at last she regains enough control over herself to speak, all she can manage is a hoarse "Fuck... you feel so good..." before collapsing forward, boneless and satisfied onto the cold tile floor of the shower, her limbs sprawled out around your waist and legs.

Shit... we really did cross the line this time... But it felt so right... And your cock... I swear, it was like magic in my pussy... I just couldn't say no...

I know... I felt it too... You were like an addiction and now that I've had a taste of what we could be together, there's no going back to how things used to be... But do you think your girlfriend would understand? And what about her feelings? We should probably at least try talking to them first before making any rash decisions.

Hmm... I suppose we could try sneaking around for a while longer but secrets have a way of getting out sooner or later. Maybe once things cool down we can figure something else out, yeah? In the meantime, just remember that you're mine tonight and tomorrow and any other night you need me to be. Okay?

Alexis leans in close, pressing her lips against his ear as she whispers those last words, sending a shiver of desire down his spine. She wraps one arm around his waist while using the other to cup his balls, squeezing gently. Her hips begin to rock against him again in a slow, sensual grind that has his cock twitching for more of her heat.

Oh god... not again... I can't say no to you, can I? Just one more time, and then we should probably find somewhere to rest before someone realizes what we're doing.
