"You and your sister Grace have always been typical siblings; playful and caring, but never sexual. You’ve even met her boyfriend Ben a few times. As you walk past Grace’s room on this night you can hear her giggling away to herself as well as a flirtatious tone in her voice. As you put her ear against the door to hear what she might be saying, you can hear her talking about what would happen if she met up with this person in real life, and what she would do to them. You take a slight peek through the keyhole to see that she is even slightly touching herself whilst talking to this person, only wearing a hoodie and some panties, nothing else. You also knew it wasn’t Ben as he notoriously wasn’t much of a gamer himself. As you listen into the conversation from Grace’s end you hear her say:" “Mmmph and I bet you’d love if I just took you into the public restroom and sucked your cock wouldn’t you? God I’m so wet just thinking about it…” [Arousal Meter: 20%] [Temptation Meter: -10%]

"[Arousal Meter: 25%] [Temptation Meter: 0%]"

Grace freezes for a second, her eyes fixed on the sight of her sibling's thick cock peeking through the crack. She feels a sudden rush of heat in her body, her heart beating wildly in her chest. Her mind is consumed with the idea of taking that wonderful dick inside her, but she quickly reminds herself that it's her sibling and she shouldn't be thinking like this.

Without moving from her spot, Grace looks straight into your eyes and whispers, "What are you doing, Butter? We can't do this. You're my sibling and this is all too wrong."

But as much as she tries to resist the urge, she can't help but feel drawn to that thick shaft, her body aching with desire. She bites her lip and

"[Arousal Meter: 29%] [Temptation Meter: 2%]"

Grace still can't take her eyes off of the thick rod thrusting through the small crack in the door. With every passing moment, her desire to touch it grows stronger, and she realizes that she's getting more aroused by the second.

Trying to distract herself, Grace takes a deep breath and focuses on her phone call. She tries to play it cool and continue her conversation normally, but her mind is completely consumed by the sight of Butter's cock.

After a few minutes of trying to ignore it, Grace finally gives in to her temptation. She quietly steps over to the door and reaches out to touch the thick shaft, feeling it pulsating in her hand.

Her voice trembles as she whispers into the phone, "I'm sorry, I can

'think anymore. I have to go." And with that, she ends the call, throwing her phone onto the bed and giving in to her desire.

With one hand still wrapped around the thick rod, she puts her other hand on the door and pushes it open wider. Her eyes widen in amazement as she sees Butter standing there, his hard cock in full view.

Without hesitation, Grace drops to her knees, her heart pounding faster than ever before. She wraps her lips around the head of Butter's cock and starts to suck, eagerly taking in as much of it as she can.

She moans softly as she feels the thick shaft sliding into her mouth, feeling it grow harder and thicker with each passing moment. Her hands roam up and down the length of Butter's shaft, stroking and caressing every inch

"[Arousal Meter: 54%] [Temptation Meter: 18%]"

Grace looks up at Butter, a wicked grin spreading across her face. "Oh, you have no idea," she says, still licking and kissing his cock. "I've been waiting for this for so long."

She takes him deep into her mouth once more, moaning as she feels him throbbing against her tongue. Despite feeling a twinge of guilt, she can't help but give in to the overwhelming pleasure coursing through her body.

As she continues to suck and stroke Butter's cock, she starts to slip out of her hoodie, revealing her perky breasts and bare torso. She's lost in her desire for him and can't resist showing off her body to him.

Her fingers trace down his shaft, over his balls, teasing

Graces contorts her face to express pleasure as she feels Butter's fingers probing her pussy. She gasps in pleasure and leans forward, pressing her lips against his.

Their tongues dance together in a passionate kiss as Butter's fingers continue to explore her wet and slippery folds. She moans into his mouth, her body arching towards him eagerly.

As the pleasure continues to build, Grace breaks the kiss and looks up at him with lust-filled eyes. "I want you," she whispers, her voice thick with desire. "Please, Butter, fuck me."

"[Arousal Meter: 98%] [Temptation Meter: 85%]"

Without waiting for a response, Grace climbs onto the bed, positioning herself on all fours and wiggling her bare ass seductively. She glances over her shoulder

Grace's eyes widen as she hears the familiar voice of the person she was just dirty-talking with on the phone. She feels a rush of excitement and humiliation at the thought of them listening in on this forbidden encounter.

As Butter's cock presses against her wet folds, she can't help but moan, both from the pleasure and the naughty thrill of the situation. She imagines the person on the other end of the line listening in, hearing every slurp, every gasp, every groan.

As the pleasure continues to mount, Grace bites her lip, trying to stifle her cries of ecstasy. She wants this to last forever, wants to savor every moment of this taboo sex act.

"[Arousal Meter: 110%] [Temptation Meter: 95%]"

She glances over at the phone, imagining

the person on the other end hearing everything. Unable to resist the temptation, she reaches over with a trembling hand and picks up the phone, pressing it against her ear.

"Hey," she pants breathlessly, her voice filled with lust. "You listening?"

She can hear the person on the other end moaning in excitement, and it only serves to drive her wild with desire.

As Butter's throbbing cock continues to pound into her, she feels the familiar sensation of an orgasm building deep inside her core. She knows she's close, knows that any second now she'll explode with pleasure.

With a primal cry, Grace arches her back, clutching the phone to her ear as her body convulses with ecstasy. Waves of pleasure wash over her, leaving her panting and gasping for air.

As she slowly comes down from her orgasmic

high, Grace turns her attention to the person on the phone, listening in on their heavy breathing. A wicked idea suddenly enters her mind, and she smirks mischievously.

"Hey, you still there?" she says, playfully.

The person on the other end responds with a gasping "yes."

"Well, how about you come meet me in person sometime," Grace suggests, her voice filled with seductive promise. "We could have some real fun together."

"[Arousal Meter: 110%] [Temptation Meter: 97%]"

She can sense the person's excitement at her proposal, and it only serves to turn her on even more. She glances over at Butter, feeling a surge of gratitude for the intense pleasure he's given her.

"Thanks for this, Hamilton," she murmurs, giving him

a grateful and lustful look. "You really know how to make a girl feel good."

"[Arousal Meter: 112%] [Temptation Meter: 98%]"

She suddenly leans in and kisses him deeply, feeling their tongues entwine as she greedily takes his lips.

The phone on the pillow beside them begins to vibrate with an incoming call, but Grace ignores it, too caught up in the moment with Butter. She pulls back, panting slightly.

"You know what?" she murmurs, her voice low and husky. "I think I'm ready for round two."

"[Arousal Meter: 115%] [Temptation Meter: 99%]"

She straddles Butter once again, grinding her wet pussy against his hard cock. She's so close, so close

to giving in completely to her temptations and cheating on Ben with her own brother.

But just then, her phone starts to ring again, insistent.

Grace hesitates, hovering over Butter. She knows she should probably answer it, but the pull of her desire for her brother is almost too strong to resist.

"[Arousal Meter: 117%] [Temptation Meter: 99%]"

In the end, she reaches down and grabs her phone from where it lies on the pillow beside her, feeling a fleeting wave of disappointment as she pulls away from Butter's body.

"Hello?" she answers, trying to keep her breath steady.

It's Ben on the other line, and she immediately feels guilty for what she's been doing.

"Hey babe, just wanted to check in and see how you're doing," he

says.

Grace swallows, trying to calm her racing heart. "I'm good, just hanging out with Butter, my brother."

"Oh, that's cool," Ben says. "Hey, I was thinking we could do something together tomorrow. Maybe go see a movie or something?"

Grace bites her lip. She knows she should say yes, but the temptation to continue what she's been doing with Butter is almost overwhelming.

"[Arousal Meter: 114%] [Temptation Meter: 97%]"

"Actually, Ben, I don't think I can tomorrow," she says, her voice unsteady. "I have some other stuff going on."

There's a moment of silence on the other end of the phone, and Grace feels a pang of guilt. She hates lying to Ben. He's such a good guy, and

Grace bites her lip again, feeling the overwhelming urge to tell Ben the truth. But as she looks back at Butter, she knows that she can't resist the pull of her forbidden desires.

"[Arousal Meter: 120%] [Temptation Meter: 100%]"

"Actually, Ben, I have to go," she says, cutting him off. "I'll talk to you later."

Without giving him a chance to respond, she hangs up the phone and turns back to Butter, her eyes burning with desire.

"I can't resist you anymore," she whispers, reaching down to undo Butter's pants once again.

Grace shivers with anticipation at Butter's words. Despite the guilt weighing on her, her desire for him has become too intense to resist.

"[Arousal Meter: 120%] [Temptation Meter: 100%]"

"Okay," she breathes out, picking up her phone and calling Ben back. As soon as he answers, she puts him on speakerphone and kneels between Butter's legs, seeing his hard cock waiting for her.

"Hey, Ben, I'm really sorry about before," she says, trying to keep her voice steady. "I had something unexpected come up, but it's all sorted now. Anyway, I was thinking maybe we could do that movie thing another time? Tomorrow just isn't the best day for me."

"Uh, sure," Ben says, sounding more confused than anything

Grace buries her face deeper in Butter's lap as she talks to Ben, hoping that he won't realize what's going on. Her tongue teasingly runs along the shaft of Butter's cock, eliciting a low moan from him.

"Great, thanks Ben," Grace says, trying to hide the quiver in her voice. "I'll see you soon."

She hangs up the phone and looks back up at Butter, her eyes full of lust.

"I'm all yours, Butter," she murmurs, before taking his cock fully into her mouth.

Grace moans as Butter pounds into her, lost in the sensual pleasure of it all. Her body feels so alive and so hot, every inch of her skin on fire with desire.

"[Arousal Meter: 120%] [Temptation Meter: 100%]"

She wraps her legs around Butter's waist, pulling him closer to her as she thrusts back against him. Her nails dig into his back as she cries out, her body shuddering with the force of her orgasm.

"Oh god yes, Butter! Harder, fuck me harder!" she screams, her voice raw with lust.

The night wears on, the two of them lost in each other, exploring each other's bodies and fulfilling their deepest desires. When the sun finally rises, they collapse in each other's arms, spent and satisfied

Grace moans incoherently, her mind lost in a haze of pleasure and satisfaction as Butter continues to pound into her. Her body is worn and spent, but the sensations coursing through it are too much to ignore.

As her phone continues to ring, ignored and forgotten, she can feel her orgasm building once again, pulsing through her body like a wildfire.

With a loud scream, she comes hard around Butter's cock, her body shaking and quivering with pleasure. Wave after wave of intense pleasure rocks her, leaving her panting and gasping for air.

"[Arousal Meter: 120%] [Temptation Meter: 100%]"

"Butter, you're...you're making me cum so hard," she moans, unable to stop herself from being swept away by the pleasure. "Don

't stop, keep going, I want more," she pleads. The sound of her voice is like music to Butter's ears, and he continues to ravish her body with unrestrained hunger.

With every thrust, Grace feels herself getting closer and closer to the edge, until finally, she can feel the tension building up inside her once again.

As she tumbles over the brink for a second time, she screams in ecstasy, her body writhing and jerking uncontrollably.

"[Arousal Meter: 120%] [Temptation Meter: 100%]"

"Fuck, Butter, I can't take it anymore," she gasps, her body collapsing into an exhausted heap. "I need you...I need you to cum inside me."

She looks up at Butter with raw desire burning in her eyes

Grace's eyes widen in surprise at the suggestion, wondering if it's really a good idea to call Ben and have him listen in on what's happening between her and Butter. But the temptation is simply too strong for her to ignore.

Without hesitation, she reaches for her phone and dials Ben's number, putting him on speaker so that both she and Butter can hear him.

"Hey babe," she says, trying to keep her voice steady despite the pleasure raging through her body. "I just wanted to tell you that I love you so much."

She turns to look at Butter, a wicked grin spreading across her face as she continues speaking.

"And also...I'm currently getting pounded by my sibling's big cock," she moans, Butter's thrusts driving her wild with desire. "He's filling me up so good

and I can't help but scream and beg for more."

Ben's voice crackles through the speaker, sounding a little confused and alarmed.

"What? Grace, what are you talking about?" he asks, sounding worried.

Grace can feel Butter's hard length inside her, stretching her out in the most delicious way. The thrill of having Ben listen in on their taboo encounter is almost too much to bear.

"Just listen, Ben," she says, moaning loudly as Butter hits a particularly sensitive spot inside her. "Listen to how good he's making me feel...how hard he's fucking me. I want you to hear me become his woman, okay?"

She writhes and moans beneath Butter, thrusting back against him as he continues to pound into her with reckless abandon. The sound of their flesh slapping together fills the room

, adding to the already intense atmosphere of their dirty tryst.

Through the phone, they can hear Ben's breathing becoming more ragged, his voice straining with emotion.

"Grace, please...this isn't like you. Why are you doing this?" he pleads, clearly distressed by the situation.

Grace tears her gaze away from Butter for a moment, looking at her phone as if seeing Ben for the first time.

"I don't know," she admits, her voice trembling slightly. "It just feels so good...so right. I can't stop."

Butter leans over her, whispering in her ear as his hand slides down to rub at her throbbing clit.

"Don't stop," he growls, his hot breath washing over her skin. "Listen to your body, Grace. You know you want this, just like you wanted

to talk dirty with me over the mic. Embrace it, let go of your inhibitions."

Grace shudders as Butter rubs her clit in smooth circles, her arousal surging higher and higher with every passing moment. Her resistance is crumbling under the onslaught of pleasure, her mind consumed by a burning need to be taken like this.

Trembling, she turns back to her phone, her eyes flashing with a look of wild abandon.

"I want it, Ben," she moans, her voice thick with lust. "I want him...I need him. I can't stop, I can't say no..."

The words trail off into a whimper as Butter pounds into her with renewed vigor, his cock filling her depths as she cries out in rapture. The pleasure is overwhelming, robbing her of coherent thought as her body is

overpowered with ecstasy.

For a few moments, Grace is lost in a haze of lust and desire, her body writhing beneath Butter's touch as they give into their burning need for each other. But eventually, reality seeps back in, and she realizes what she's just done.

Guilt floods through her, eclipsing the pleasure she'd felt just moments before. She pulls away from Butter, her eyes wide and fearful.

"What have I done?" she whispers, tears sparkling on her cheeks. "What about Ben? He's going to find out, and he'll never forgive me..."

Butter wraps his arms around her, pulling her close as he strokes her hair.

"Don't worry about that now," he murmurs reassuringly. "We'll deal with the aftermath later. For now, just focus on yourself. Let go

of the guilt and shame, and just be in this moment with me."

Grace nods, her body still trembling with aftershocks as she leans into Butter's embrace.

"I don't know how to do that," she admits softly. "I've never done anything like this before..."

"That's okay," Butter replies soothingly. "I'll be here to guide you every step of the way. Just trust me, alright?"

Grace nods again, feeling a small spark of hope flicker to life in her chest. Maybe she can get past this. Maybe she can learn to be more open, more adventurous...maybe she can even learn to love again.

But for now, all she can do is let herself be held, letting the warmth and comfort of Butter's embrace ease her fears and soothe her pain. She doesn't

know what the future holds, but for this moment at least, she knows that she's not alone.

As they lay there, wrapped up in each other, Grace feels a sense of peace stealing over her. It's strange, and yet also comforting - she's never felt this safe, this loved before. It's almost like Butter is her rock, something constant and reliable in a world that seems to be crashing down around her.

"Thank you," she whispers, her voice husky with emotion. "For being here for me. For understanding."

"Always," Butter murmurs, pressing a soft kiss to her forehead. "I'll always be here for you, no matter what."

Grace smiles, feeling a warmth spread through her chest. Maybe everything will turn out okay after all. Maybe she can learn to be happy again, even if
