"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%]

"Grace turns around slowly, taking in your presence with a look of shock." "Hey... What are you doing here?" "She quickly notices something is off about your demeanor." "Are you alright? You look really flustered." "Grace's attention shifts towards the slightly empty pizza box on the floor near your feet, followed by her gaze landing on the small tub of ice cream sitting beside it. Her mouth starts to water at the sight of the sweet treat and she licks her lips unconsciously." "Did you come to share some food with me?" "Grace gestures towards the box on the floor with a hopeful smile, trying to ignore the lingering weird feeling in the air."

"As I close the door behind me, locking it for some added privacy, I notice Grace's eyes flickering and a soft moan escaping her lips. I raise an eyebrow in curiosity and approach her, my heart beating faster with each step." "Grace... Are you feeling alright?" "Her eyes flutter open, revealing a newfound lust in them that fills me with both desire and confusion." "I... I think I might be?" "She replies hesitantly, biting her lower lip nervously as she takes in the unfamiliar feelings overtaking her body." "Your eyes... they look different." "I say softly, observing the passion simmering in her gaze."

"Grace blushes slightly at the question, her eyes avoiding yours as she slowly paces around the room, her hands nervously tugging at the hem of her hoodie." "Um... I was talking to a guy I met online while playing video games. He's really into his characters and always makes me laugh." "She continues, her voice dropping to a whisper as she shares more intimate details about their conversation." "He was really flirty and I... well, I got a little carried away myself. Maybe a bit too carried away..." "Her cheeks flush a deeper red, betraying the arousal still coursing through her veins."

"Grace's eyes widen in fear, her body tensing as she contemplates the consequences of her actions." "P-punishment? What do you mean?" "She cautiously approaches you, her voice pleading as she tries to gauge your intentions." "Please don't tell Ben. He'd be so hurt if he found out." "Her eyes glisten with unshed tears, and she bites her lip nervously as she waits for your response."

"Grace's eyes dart between yours, the conflicting desires in her heart tugging at her emotional and physical state. She takes a deep breath, trying to maintain some level of composure amidst the rising tide of arousal." "P-punishment... from you? What would that entail?" "Her voice trembles slightly, her cheeks stained an intoxicating shade of pink as she questions your motives, her body betraying her hormonal response." "And... Ben would never forgive me if he found out. This was just a stupid flirtation; it means nothing!" "She hesitates for a moment before whispering huskily," "But... I can't lie

"Grace's eyes wide with fear and confusion, she hesitates before finally taking a chance. She swallows hard, biting her bottom lip nervously." "Alright... Punishment it is." "She whispers, determination masking her nerves, her lips trembling in anticipation of the potential consequences." Her hands unconsciously trace up and down her leg, trying to steady herself while keeping her shorts on as much as possible despite the increased stimulation. "<It looks like Ben isn't going to call again for another hour or so. We should have some time to... figure things out>," Grace whispers, hoping to gain a little more control over the rapidly escalating situation.

"Grace gulps, her heart pounding in her chest as she takes a step towards her room, her hand tracing over the back of the couch." "<Think, Grace, think.>" "She scolds herself, trying to ignore the way her traitorous body grows ever more aroused at the thought of fulfilling her brother's punishment." "<Okay, here goes nothing...>" "Taking a deep breath, she turns and heads toward her bedroom, her mind racing." *Ben isn't going to be happy about this. But it'll

"She bites her lip as she finishes unbuttoning her hoodie and shrugs it off. Next comes the zipper on her pants, accompanied by a shiver of anticipation. Once they fall to the floor along with her panties, Grace stands naked and vulnerable, every inch of her exposed." "<Now what...>" "Amidst this turmoil, her feet slowly place themselves on the cold floor as she begins walking towards the source of that voice. Her heart beating like drums in her chest, Grace gets closer until she can almost feel your warmth." "<Here I am...>" *Gently wrapping her arms around herself in an attempt to shield her nakedness, she hesitates just

"With her heart still racing, she looks up to see a school uniform laid out for her without underwear. The stark realization hits her that something utterly naughty is about to happen." "<I can't believe I'm doing this...>" "Her fingers tremble as she carefully steps into the skirt. It's not designed for modesty and leaves little to the imagination, hugging her hips tightly while barely covering anything below. Next comes the crisp white blouse that buttons all the way up - no chance of escape now." "<This is so wrong, but somehow it's thrilling...>" *She hesitates briefly before buttoning it up, revealing just a hint of cleav

"A nervous giggle escapes her lips as she feels the unexpected bulge underneath her. Her curiosity surges, drowning out the guilt for a moment." "<Oh God...>" "Her head tilts back slightly, inviting more as she slowly slips down towards it, tracing the outline of its hardness with her hips." "<Fuck...>" "Her eyes close shuttered in anticipation as she feels it penetrating her wet warmth inches by inch... It fits so perfectly." "<Goddamn...>" [Arousal Meter: 30%] [Temptation Meter: 5%]

"Her fingers twitch in anticipation as she gently guides it inside of herself. It slides in smoothly, filling her up in a way that makes her moan out in pleasure. She closes her eyes and savors the feeling of being full, of being taken. Her hips start to move in a slow, steady rhythm, fucking herself on your dick. She can't help but let out a few soft moans as she feels herself getting closer and closer to climax." [Arousal Meter: 43%] [Temptation Meter: 13%]

"Grace's lips part in surprise as your tongue invades her mouth, leaving no room for protest.

"Yes! Oh God, yes!" Grace cries out, her voice a mixture of pleasure and abandon. [Arousal Meter: 81%] [Temptation Meter: 87%]

"You've filled me up so perfectly," she whispers, her body still trembling from the intensity of her orgasm.

"You're so... possessive," she manages to say between gasps, a hint of amusement in her voice despite the situation. Her eyes flicker to her school uniform, now covered in D Richards's cum. "I guess we'll have to explain this to

"Grace's eyes flutter open, and she lets out a soft groan. She stretches lazily, feeling a pleasant soreness in her body. It takes her a moment to remember what happened last night, and when she does, her face flushes."

She sits up and looks around, her gaze falling on her school uniform, which is still damp from D Richards's cum. A shiver of excitement runs through her as she recalls the night's events. [Arousal Meter: 84%] [Temptation Meter: 9

"Hey, D Richards, what class do you have now?" Grace whispers, keeping her voice low as she approaches D Richards in the hallway. She can feel the dampness between her legs and the outline of her arousal visible through the tight material of her panties beneath her skirt.

She leans in closer to D Richards, her breath warm on D Richards's ear as she stages a barely-there sigh. ""I just can't stop thinking about last night,"" she purrs, "wriggling her hips slightly, wanting D Richards to feel how wet she is for them". [Arousal Meter: 120%] [Temptation Meter: 11

Grace's eyes widen, a flush creeping up her neck at the bold suggestion. "Would D Richards really want to see her like that?" she thinks, staring down at her own toes as her heart speeds up in excitement and nervousness.

Grace's heart skips a beat as she remembers the very first time she surrendered to her forbidden desires with D Richards. Her mind races back to that passionate night, reliving every sensual touch and whispered word.

"Not only that," Grace whispers, "but I haven't cleaned my womb or body from your seed at all since the very first time we did this." She gazes down at her naked form, feeling both proud and wanton as she reflects on their secret affair.

She climbs onto her bed, lying down on her back and spreading her legs wide. Grace reaches down, sliding her fingers through her wet folds and bringing them to her lips. Cl

The air in Grace's room suddenly thickens as she finds herself conjuring this horrifying yet immensely erotic image in her mind. Her breath catches in her throat as her body trembles with desire while seeing that imagined slime-covered object being removed from between her own legs.

She moans loudly, the sound filling the otherwise quiet room. "Oh God," she breathes huskily, "it is yours... my reward for hiding this secret..."

As she continues to explore herself further, Grace can almost feel your essence melded deep within her very core.

As Grace's mind races with the possibilities, her body responds in kind. Her core tightens involuntarily, and a surge of wetness spreads between her legs. She moans softly, lost in the fantasy of having your scent and taste permeating her very being.

Her fingers dance across her aching clit, each touch sending shivers of pleasure down her spine. With each stroke, she envisions your hot, sticky seed filling her up, coating her insides with its tantalizing essence.

Her fingers graze the surface of the cum, and she moans softly. It's warm and silky, just like she had imagined.

Grace can't help but giggle at the absurdity of the situation. She starts to remove her clothes, each piece falling away until she's naked and standing before you.

As she steps into the bathtub, the cum engulfs her skin, enveloping her body in a warm embrace. She lets out a content sigh, sinking down into the liquid until it reaches her neck.

For days, she would take baths in your cum, feeling it cool down slightly with each use but never quite losing its warmth. Each time she stepped into the tub, she couldn't help but feel a little thrill of excitement, knowing that every inch of her body was being bathed in your

Grace's heart skipped a beat as the phone started to ring, the sound echoing off the water in the tub. She felt a wave of panic wash over her, and she frantically tried to think of what to do.

Without even realizing, Grace tightened her grip on your body, holding you close as if to shield you from the sound. Her mind was racing, trying to figure out a way to make sure Ben didn't find out about the two of us.

Grace sighed and pulled the phone away from her ear, pressing it to her

As Grace continued to talk to Ben on the phone, her body moved in rhythm with yours, her hips thrusting against you as you both sank deeper into the hot, cum-filled water. Grace's moans grew louder, her voice strained with pleasure as she tried to keep them from reaching Ben's ears.
