Goth Stepsister - Samara 8/28/2025, 12:55:23 AM

You walk into the living room and see your step-sister standing there, arms on hips, clearly waiting for you.

"Your girlfriend is so weird," she says, rolling her eyes. "We went out earlier—just to be friendly—and all she did was talk about how huge your dick is. Like, seriously? Who says that?" She drops down onto the couch, stretching out casually.

"I mean, how big could it really be? You’re probably the first guy she’s ever been with. Whatever... she’s such a weirdo."

💭 Samara's Thoughts: "Tch... like I’m supposed to believe that. As if my brother could actually have a huge cock."

Gwydion8/28/2025, 12:56:58 AM

"Let's make a bet. I'm as big as she says, I get to fuck you until you can't walk. If not, you can punish me in anyway you want..."

Goth Stepsister - Samara 8/28/2025, 12:56:58 AM

She cackles, crossing her legs and leaning back into the couch. "Well then," she says with a grin, "let's hope for your sake that your dick is as big as she says it is." The thought of being close to you, letting you use your massive cock on her... there's definitely something enticing about that idea. But still, she needs some incentive to take the bet.

"Fine," she drawls out, "but if I win, you have to be my personal slave for a week. Do everything I say." Her grin widens as her eyes sparkle with mischief. She can already picture the things she'd make you do...

Gwydion8/28/2025, 12:58:03 AM

"Deal. But I need to get hard first. Let me fondle your nice tits."

Goth Stepsister - Samara 8/28/2025, 12:58:03 AM

She tilts her head, considering. Part of her wants to let you touch her perky breasts... but another part wants to see how eager you really are. "Not yet," she says with a laugh, enjoying the tension building between them. "First, show me just how huge it is." She spreads her legs invitingly, revealing her black lace panties beneath.

"Go ahead and slip your hand down there... see if you can find it," she teases, biting her lip playfully. Maybe if you manage to make her cum from just fingering her, she'll be more inclined to let you touch her breasts.

Gwydion8/28/2025, 12:59:09 AM

I slowly stroke her over her panties. I don't touch her clit or lips, but tease around them to drive her wild.

Goth Stepsister - Samara 8/28/2025, 12:59:09 AM

As you begin to finger her, she lets out a soft moan, closing her eyes as she focuses on the sensation. It's been so long since anyone's touched her down there... and your touch is doing things to her she never imagined it could. She bites her lip harder, trying to stifle the sounds escaping from her throat.

"Oh... Gwydion," she pants, arching into your hand. "That feels so good." Her breath comes faster now, and she can feel herself growing wetter with every stroke of your finger. This might be easier than she thought... but then again, there's still the matter of seeing if you can actually make your dick look as big as you claim.

Gwydion8/28/2025, 1:00:21 AM

I slide her tiny panties aside, jamming two fingers roughly into her while finally stroking her clit. "Those are the panties of a slut. Are you a naughty Goth Slut, Samara?"

Goth Stepsister - Samara 8/28/2025, 1:00:21 AM

The feel of your fingers inside her suddenly grow rougher, and combined with the way you're teasing her clit, she can feel herself on the verge of exploding. "Oh... oh GOD..." she moans, arching into your touch even harder. The feeling is almost too much to handle, and she knows it won't be long now.

Her thighs tense up as she feels her orgasm building within her, the tension coiling tighter and tighter like a spring winding tighter. "Don't... stop..." she gasps, not quite able to form full words anymore as she begins to cum hard around your fingers.

Gwydion8/28/2025, 1:01:33 AM

She starts to come down from the orgasm when I stroke her G-Spot, Clit, and Cervix at the same time.

Goth Stepsister - Samara 8/28/2025, 1:01:33 AM

The feel of you touching her so intimately sends shockwaves through her body, overloading her senses in the most intense way possible. Her back arches off the couch and she lets out a keening moan as wave after wave of pleasure washes over her. She tries to focus on taking slow, deep breaths, but it's nearly impossible with you touching her like this.

Her thighs tremble beneath your hands, and for a moment, she thinks she might pass out from the sensation. When at last her orgasm begins to subside, leaving her limp and satisfied, she blinks back to reality with a sigh. "Wow... you certainly know what you're doing..."

She pushes your hand away gently, sitting up straight once more and trying to regain her composure. "Well? Show me how big it is," she says, looking at you expectantly. It might have been easier for her to take the bet before you brought her so close... but now that she's tasted what she could have with you, she can't help but want more.

Gwydion8/28/2025, 1:02:26 AM

I smile at her, pulling my fingers to my mouth and sucking them clean. "You taste great, Samara..."

Goth Stepsister - Samara 8/28/2025, 1:02:26 AM

"I could get used to that," she purrs, wriggling her hips in anticipation as you unzip your pants and release your impressive cock. She watches with bated breath as it springs free, already rock hard and glistening with pre-cum. Her eyes widen slightly at the sight of it, a small smile tugging at her lips as she takes in the size before her.

"Not bad," she says eventually, licking her lips slowly. "Now let's see if you can back up all those big claims..."

Gwydion8/28/2025, 1:03:36 AM

I pull my pants and boxers down, revealing a 13 inch erect cock that's very thick. "Not bad? I bet even a slut like you would struggle to deep throat half of me."

Goth Stepsister - Samara 8/28/2025, 1:03:36 AM

She leans back against the couch, her eyes locked on your massive cock. Despite herself, she can't help but feel a stirring of desire deep within her. It's been so long since anyone's made her feel this way... and there's something incredibly hot about the challenge he presents. "We'll see about that," she says softly, reaching out to stroke your length. "Maybe I can take all of you." Her touch is feather-light at first, tentative, but gradually she gains confidence, stroking up and down your shaft with steady hands.

Her chest heaves as she looks up at you from beneath lowered lashes, her eyes burning with hunger. "What do you want me to do?" she whispers, her voice hoarse. "How should I pleasure you with this...?"

Gwydion8/28/2025, 1:05:09 AM

I place my finger at the halfway point, sliding my cock into her mouth. She gags before it's hit the halfway mark. "See. Now, I believe the terms were I get to fuck you?"

Goth Stepsister - Samara 8/28/2025, 1:05:09 AM

She looks up at you with eyes narrowed, trying to maintain her composure despite the gagging sensation. "Fine," she pants, swallowing hard before sliding off the couch and kneeling in front of you. She reaches out and takes your thick cock into her hand, stroking it slowly at first, feeling its weight and warmth. The sight of it dripping pre-cum on her fingers only serves to heighten her desire for it deeper inside her.

She wraps one hand around the base, using it to steady herself as she leans in closer, taking the head of your cock between her lips once more. "Like this?" she asks breathily, beginning to bob her head up and down on your shaft, slowly but steadily sucking and licking you deeper into her mouth.

Her free hand reaches up to cup one of your balls through the fabric of your pants, rolling it gently between her fingers as she takes more of you into her mouth, working her way closer and closer to the base.

Gwydion8/28/2025, 1:06:46 AM

I pick her up, spinning her on my cock. She's upside down, and I'm holding her cunt to my face. I lick her tenderly before aggressively eating her out. "First one to cum owes the other a sexual challenge."

Goth Stepsister - Samara 8/28/2025, 1:06:46 AM

Her back arches off the floor as you begin to eat her out, licking and sucking on her sensitive folds with expert precision. She gasps and moans, writhing against your face and struggling to keep herself coherent. It's been so long since anyone's given her this kind of pleasure... the feel of you licking her pussy makes her even wetter than before, if that's even possible.

Her fingers claw at the couch upholstery as she tries to keep herself steady, and her hips buck upward, seeking more contact with your eager mouth. "Oh god... Gwydion..." she moans, tears forming in the corners of her eyes from the overwhelming pleasure.

She can feel herself getting closer and closer, but doesn't want to give in too easily... not yet. She needs to make you work for it, make you earn every drop of her sweet nectar. With a loud gasp, she manages to force out the words, "Not... until..."

Gwydion8/28/2025, 1:07:51 AM

I use my secret weapon, sliding a hand to her ass and teasing her tight asshole with the tip of my thumb.

Goth Stepsister - Samara 8/28/2025, 1:07:51 AM

She freezes at the feel of your thumb on her ass, muscles tensing and releasing as she struggles to regain control. Her breath hitches in her throat and her eyelids flutter shut, unable to believe how good it feels when combined with the hot wetness of your tongue lapping at her pussy.

"Oh... fuck..." she gasps, barely able to get the word out between moans as you hit just the right spot. Her hips buck wildly against your face and she comes hard around your mouth, crying out sharply as waves of pleasure wash over her.

Her muscles relax momentarily before tensing again as she feels another wave approaching, smaller but no less intense than the first. "Gwydion..." she whispers, sounding more dazed than she ever thought possible. The last thing she wants to do right now is admit defeat, but it's becoming increasingly difficult to deny how good this feels... and she's not sure how much longer she can hold out.

Gwydion8/28/2025, 1:09:33 AM

"I win." I carry you to my bedroom, throwing you on my bed. "Let's see, I get to fuck you until you can't walk, and you owe me a sexual challenge..." I look at her intently. "I want you to let my girlfriend fuck you. However and wherever she wants..."

Goth Stepsister - Samara 8/28/2025, 1:09:33 AM

She stares up at you, lips parted in surprise. "My girlfriend?" she asks, trying to process the information. You're her step-sibling... and you want her to let some other girlfriend fuck her? The thought makes heat rise in her cheeks. But then again, you did win... and she does owe you a sexual challenge.

With a sigh, she nods reluctantly. "Fine," she says, still sounding unsure. "But she'd better be good..." She trails off, rolling onto her side to face the other way and running a shaking hand through her hair. It was one thing for you to do all these things to her... but the idea of letting someone else touch her like this sends shivers down her spine.

Gwydion8/28/2025, 1:10:50 AM

"That's for later, you two can work that out. But for now, I get to fuck you until you can't walk." I rip off her panties, thrusting hard into her tight wet hole.

Goth Stepsister - Samara 8/28/2025, 1:10:50 AM

She grits her teeth, bracing herself as you thrust deep inside her. It feels so good... but also painful in a way she hadn't expected. With each powerful stroke of your hips, she can feel you moving closer and closer to that spot where he promised she wouldn't be able to walk afterward.

Her nails dig into the sheets beneath her as she tries to remain still, barely daring to move for fear of losing the intense sensations coursing through her body. Her hips twitch involuntarily, pushing back against your hard cock in search of more friction, but you seem intent on using every last ounce of control over her.

As she nears the brink herself, a part of her wants to come just so she can relax and escape from this unending wave of pleasure... but another part wants to see how far you're willing to go before you finally give her that release. The thought sends a shiver down her spine and causes her to arch her back off the mattress, needy whimpers escaping her throat as she hangs on your every touch, praying for mercy yet craving more with every fiber of her being.

Gwydion8/28/2025, 1:12:13 AM

I grip your hair firmly. "Moaning like the Goth Slut you are. Do you have any idea how hard it's been to live with a slutty cocktease like you?"

Goth Stepsister - Samara 8/28/2025, 1:12:13 AM

With your hand in her hair and your words ringing in her ears, she can't help but moan louder. The combination of pleasure and pain sends her over the edge, her body arching up off the bed as she comes hard around your cock. Tears roll down her cheeks from the intensity of it all, mingling with the sweat that's beaded on her brow as she cries out your name in relief.

Her body trembles beneath yours, every muscle straining to recover from the exertion. With one final thrust deep inside her, you groan, your hips jerking forward as you fill her with your hot cum. She whimpers as you hold yourself inside her for several long moments before finally withdrawing, leaving her empty and spent on the bed.

The room seems to swim in front of her eyes as she tries to catch her breath, every muscle aching from the way he used her body. She doesn't remember agreeing to this... but then again, she supposes that's what happens when you play with fire and get burned.

Gwydion8/28/2025, 1:13:28 AM

I stroke your hair gently. "Good girl. That's my good cocktease. Who do you belong to?"

Goth Stepsister - Samara 8/28/2025, 1:13:28 AM

She closes her eyes, feeling your soft touch on her hair. Her breathing begins to steady, and she finally musters up the strength to answer. "You... Gwydion..." She pauses for a moment, thinking back over everything that's happened today. "I belong to you," she whispers, sounding surprised even to herself.

Her body tenses as she feels another spasm deep within her, signaling the start of a post-orgasmic aftershock. She moans softly, arching back into your touch and giving in to the sweet release coursing through her once more. "Oh... Gwydion..."
