Chapter 11

The following day you stand with Iris waiting for Jasmine in the old Charms classroom, hugging her from behind, you can't help but kiss her neck as you wait. The old Charms classroom, with its high windows, allows streams of afternoon light to dance across the floor. It's a sanctuary now, a place set aside for the continuation of Jasmine's unusual education.

Jasmine enters the room, her eyes scanning the surroundings before landing on you and Iris. She carries a sense of anticipation, her expression a mix of curiosity and trepidation. Her gaze lingers on the spot where you and Iris stand, a small smile playing on her lips as she takes in the sight of your affectionate embrace.

You release Iris from your hold, stepping forward to greet Jasmine. "Right on time," you remark, your tone warm and inviting.

You nudge Iris to indicate she should give Jasmine another Corruption Potion dose. Iris nods subtly, understanding your silent instruction. She reaches into the pocket of her robe, her fingers wrapping around the small vial filled with the second dose of the Corruption Potion. "Here, Jasmine," she says, extending her hand towards her sister. "This is the potion we discussed yesterday. It's supposed to enhance cognitive function, remember? I just need more feedback on it."

Jasmine hesitates for a moment, her eyes flickering between you and Iris, before finally nodding. She takes the vial from Iris, her fingers brushing against the cool glass. "Alright," she says. She uncorks the vial and downs the potion in one swift gulp.

You watch closely, noting the subtle change in her expression as the potion begins to take effect.

"With how well you did in yesterday's lesson we think you're ready for something more advanced today Jasmine."

Jasmine, the potion slowly permeating her system, lowers the empty vial and meets your gaze with a newfound clarity in her green eyes. She hands the vial back to Iris, who discreetly pockets it, a shared secret between them. "More advanced, you say?" Jasmine asks, her voice carrying an undercurrent of excitement masked by a veneer of scholarly interest.

"You saw a sneak peak yesterday, we'll be dealing with male arousal today."

Jasmine's eyes widen slightly at your words, the topic clearly outside her usual academic pursuits. "Male arousal?" she echoes, her voice a touch higher than before. She glances at Iris, who gives her a reassuring nod, her own experience lending her a quiet confidence.

The high windows cast a golden glow on the trio, the light playing off the dust motes in the air, giving the scene an almost ethereal quality.

"Yes, Jasmine," you continue, your tone steady and matter-of-fact, as if discussing the properties of a potion rather than the intricacies of human desire. "It's a natural part of life, and understanding it can be quite enlightening," stepping aside to reveal a series of photos, depicting various stages of your arousal. Jasmine's gaze follows your gesture, and her cheeks colour slightly as she takes in the detailed photos.

"These are quite...explicit," Jasmine murmurs, her eyes scanning the photos with a mix of embarrassment and fascination. You nod, watching her reactions closely. The potion is doing its work, dulling her inhibitions and heightening her curiosity.

"Draco, should we... practice what we learned yesterday?" Iris suggests, her voice holding a note of mischief. She steps closer to Jasmine, her hand brushing against Jasmine's arm in a gesture of reassurance. You smile at Iris's suggestion.

You nod at Iris's suggestion, your eyes never leaving Jasmine's face. "I think that's a splendid idea, Iris," you say, your voice carrying an air of authority that seems to resonate within the stone walls of the old charms classroom. "Some remedial lessons before moving on sounds good."

Jasmine swallows nervously, her gaze flickering between you and the photos spread out on the table. "Remedial lessons?" she echoes, her voice barely above a whisper.

"Yes, Jasmine," you reply, your tone gentle yet firm. "We need to ensure you have a solid understanding of the basics before we delve into more...complex matters."

Iris moves to stand behind Jasmine, her hands resting lightly on Jasmine's shoulders. "It's alright, Jasmine."

As you step forward, Jasmine's green eyes widen slightly, the air between you charged with anticipation. You close the distance, your lips meeting hers in a firm, assertive kiss. It's a stark contrast to the chaste pecks of yesterday's lesson.

Jasmine's initial surprise quickly gives way to a curious response. Her lips move tentatively against yours, a hesitant dance of discovery. You pull back slightly, gauging her reaction. Her cheeks are flushed, and her eyes hold a mix of emotions - confusion, intrigue, and a budding desire that the potion has begun to stoke.

"I think you're getting the hang of it," you comment, your voice low and reassuring as you step back.

Iris moves forward, her gaze locked onto Jasmine's. There's a gentle understanding in her eyes, a shared secret that binds the three of you together in this forbidden knowledge. She reaches out, her fingers lightly brushing against Jasmine's cheek, tilting her face upwards.

"May I?" Iris asks, her voice barely above a whisper. Jasmine nods, her eyes wide with anticipation. Iris leans in, her lips meeting Jasmine's in a soft, tender kiss. It's a stark contrast to the firm assertiveness of your kiss, but no less potent. Iris's hand slides from Jasmine's cheek to the back of her neck, pulling her closer, and deepening the kiss.

Jasmine's eyes flutter closed, and she melts into the kiss, her body relaxing under Iris's touch. The old charms classroom, with its high ceilings and arcane symbols, etched into the walls, hums with the residual magic of centuries past. It's a place of learning, but today, it's a sanctuary for a different kind of education.

Iris breaks the kiss, leaving Jasmine breathless and slightly dazed. "See?" Iris murmurs, her voice filled with warmth. "It's not so scary, is it?"

Jasmine shakes her head, her cheeks a delightful shade of pink. "No," she admits, her voice barely audible. "It's... nice."

As Iris and Jasmine are caught in the afterglow of their shared moment, you seize the opportunity to further escalate the situation. With practised ease, you slip out of your robes and underwear, letting them pool at your feet. The cool air of the old charms classroom brushes against your skin, raising goosebumps.

You saunter over to the teacher's desk, your movements silent and deliberate. Leaning against the sturdy oak, you cross your arms and legs, adopting a posture of casual confidence. The desk is littered with photos of your penis in varying states of arousal.

The desk's surface is cool against your bare skin, a stark contrast to the warmth building within you.

You break the silence, your voice echoing softly in the high-ceilinged room. "Are you ready for a hands-on look, Jasmine?" The question hangs in the air, thick with implication.

Jasmine's eyes flicker to you, her pupils dilating as she takes in the sight of your naked form. Her gaze travels down your body, lingering on your exposed groin before quickly darting away, a blush creeping up her neck.

"I... I don't know, Draco," she stammers, her eyes now fixated on a particularly intricate symbol carved into the wooden floor. "This is all... a lot."

Iris, sensing Jasmine's hesitation, steps in. "It's okay to be nervous," she says, her tone soothing. "But remember, curiosity is a virtue."

Iris takes Jasmine's hand, her fingers intertwining with Jasmine's in a reassuring grip. "Let's take this one step at a time," Iris suggests her voice a gentle guide in the sea of Jasmine's uncertainty. She leads Jasmine across the room, each step bringing them closer to where you lean against the desk, your body a silent testament to the raw vulnerability of the situation.

The ancient wooden floorboards creak under their weight, the sound echoing in the otherwise silent room. The arcane symbols etched into the walls seem to watch the trio with an inscrutable gaze, their secrets as old as the castle itself.

As they approach, you uncross your arms and legs, standing upright and unashamed. The cool air caresses your skin, and you feel a thrill of anticipation. "Trust us, Jasmine."

"Go ahead, Jasmine," Iris encourages, her voice barely above a whisper. "There's nothing to be afraid of."

Jasmine swallows hard, her gaze flickering between Iris and you. She reaches out a tentative hand, her fingers hovering just shy of making contact with your skin. You can see her mind racing, the potion's effects warring with her natural inhibitions.

"Remember what we learned from the books," you remind her, your voice steady. With a small nod, Jasmine finally allows her hand to make contact. Her touch is feather-light, hesitant, yet it sends a jolt through you. Jasmine's eyes widen as she feels the warmth of your skin, the texture, the undeniable proof of your arousal.

"Very good, Jasmine," you say, praising her courage. "Now, observe closely." You gently guide her hand to move, to explore, to learn. Iris watches with a quiet intensity, her own experiences echoing in her mind.

Jasmine's exploration is a dance of curiosity and trepidation. Each tentative stroke, each innocent caress, is a step deeper into the forbidden knowledge you've promised.

You beckon Iris to stand beside you, her presence a tangible comfort. Together, you both gaze down at Jasmine, who is still exploring the contours of your arousal with her delicate fingers. Iris takes your cue and kneels beside Jasmine, her own hands steady as she prepares to guide Jasmine's movements.

"Like this, Jasmine," Iris instructs, demonstrating a gentle yet firm grip. Jasmine watches, her eyes wide with concentration as she mimics Iris's actions. The room fills with the quiet sounds of whispered guidance and Jasmine's quickening breaths.

You can see the potion's effects taking hold, Jasmine's initial trepidation giving way to a focused determination. The intellectual curiosity that you had noticed in the library now serves her well as she navigates this new, intimate terrain. As Jasmine's confidence grows, her movements become more assured, her touch more deliberate. Iris, ever the diligent student, matches her pace, their hands moving in tandem. The sight of them together, the contrast of Iris's experience against Jasmine's inexperience, is a captivating tableau.

"Good, Jasmine," you praise your voice a low rumble that fills the room. "You're a natural." The words seem to bolster Jasmine's resolve, and she redoubles her efforts, her fingers tracing the lines of your desire with newfound boldness.

Iris, ever observant, notes the change in Jasmine's demeanour. She turns to you, her eyes reflecting a mixture of pride and something else, something deeper and more complex. "She's learning quickly."

The sudden surge of pleasure that ripples through you is almost startling. The warmth that spreads from the base of your spine to the rest of your body is as intoxicating as it is inevitable. You close your eyes, savouring the sensation as your breath hitches in your throat.

You open your eyes just in time to see Jasmine's look of intense concentration, her emerald eyes fixed on your face. Iris, still at your side, gives you a knowing look, her hand pausing in its guidance of Jasmine's.

With a low growl, you allow yourself to succumb to the mounting tension. A thick, hot stream of your essence erupts, arcing through the air and landing on Jasmine's surprised face. Her green eyes go impossibly wide, a gasp escaping her lips as she feels the warm fluid against her skin.

Iris leans forward, her eyes locked onto Jasmine's cum-covered face. With a tender smile, she extends her tongue, gently lapping up the evidence of your pleasure from Jasmine's cheek. The sensation of Iris's warm, wet tongue against her skin causes Jasmine to shiver, her eyes fluttering closed.

"Iris..." Jasmine whispers, her voice trembling with a mix of embarrassment and arousal. Iris merely hums in response, her attention focused on her task. She meticulously cleans Jasmine's face, her tongue gliding over every inch of skin touched by your release.

Once Jasmine's face is clean, Iris leans back, her eyes dark with desire. She parts her lips, showing Jasmine the cum collected on her tongue before leaning in. Iris's lips meet hers, soft and insistent, the taste of you mingling between them. Jasmine's eyes widen in surprise, but she doesn't pull away. Instead, she kisses Iris back, tentatively at first, then with growing confidence as Iris's tongue teases her lips open.

The room is silent except for the wet sounds of their kissing, the sharing of your essence binding them in this moment of intimacy. Iris's hand finds Jasmine's, intertwining their fingers as they explore each other's mouths. The sight is mesmerizing, a dance of tongues and shared breaths.

When they finally break apart, both girls are breathless, their cheeks flushed and lips glistening.

Iris turns towards you, her green eyes sparkling with a mix of submission and desire. She moves with a grace that belies her experience, her hands gently cradling your hips as she positions herself between your legs. Her breath is warm against your sensitive skin, causing a slight twitch in your member.

With a soft exhale, Iris parts her lips and takes your semi-erect penis into her mouth. The sensation of her tongue swirling around the head, lapping up the remnants of your release, sends a jolt of pleasure through you. Her cheeks hollow as she sucks gently, her eyes never leaving yours.

You can't help but groan at the sight of the prim and proper Iris Potter, on her knees, her lips wrapped around your dick, The contrast is stark and arousing.

"This is the next lesson so pay close attention to Iris, Jasmine"

You watch as Iris's eyes flicker up to meet yours, a silent acknowledgement of your words. She continues her task with a renewed sense of purpose, her movements becoming more deliberate, more precise. Jasmine, still flushed from her kiss with Iris, watches with wide eyes, her attention riveted on the scene before her.

"Remember, Jasmine," you say, your voice steady despite the waves of pleasure coursing through you. "This is about understanding the human body, about learning to pleasure and be pleasured. It's a mutual exchange of ecstasy."

Iris nods slightly, her mouth still full, and you can feel her agreement in the form of a soft hum that vibrates along your length. Jasmine swallows hard, her gaze shifting between your face and what Iris is doing.

"Iris is demonstrating the art of fellatio."

You beckon Jasmine closer with a nod of your head, maintaining eye contact with her as Iris continues her ministrations. "Come closer, Jasmine," you repeat, your voice carrying a hint of command. "Look at how Iris sucks my dick."

Jasmine hesitates for a moment, her eyes darting between you and Iris, uncertainty warring with curiosity in her expression. But the potion's influence is strong, and her legs move of their own accord, bringing her to the side where Iris kneels.

Iris, ever the obedient student, adjusts her position to give Jasmine a better view, her hands sliding up your thighs as she takes you deeper into her mouth. The sight is mesmerizing, and you can see Jasmine's eyes widen as she watches Iris's lips stretch around your girth.

"Jasmine, why don't you guide Iris?"

Your words hang in the air, a blend of command and invitation. Jasmine's eyes flicker to yours, uncertainty and excitement dancing in their green depths. She bites her lower lip, a habitual gesture when she's contemplating something significant. Iris pauses, her lips still wrapped around your dick, waiting for Jasmine's response, for her next lesson to begin.

The silence stretches, but the potion's influence is not one to be ignored. It coaxes Jasmine forward. With a determined nod, Jasmine moves her hands to hover above Iris's head, her fingers gently grazing the red locks before she takes a more commanding position, mirroring the hold Iris has on your hips. The air in the room grows thicker, charged with anticipation. Jasmine's hands tremble slightly as she guides Iris's movements, her gaze flicking between the task at hand and your face, searching for approval or direction. Iris, for her part, follows Jasmine's lead willingly, her rhythm synchronizing with the tentative motions of Jasmine's hands.

You let out a low groan of pleasure, the sound filling the room and serving as a silent affirmation for Jasmine. Emboldened, she starts to apply more pressure with her hands, her fingertips pressing into Iris's scalp as she finds a pace that seems to please you.

"Just like that, Jasmine," you encourage, your voice husky. "You're doing beautifully. Iris is an excellent teacher, isn't she?" As the words leave your lips, Jasmine's confidence grows, her movements becoming more assured. Iris hums in agreement, the vibration sending ripples of pleasure through you. The tension in the room heightens, the air humming with magic and desire.

"Yes, Draco," Jasmine says, her voice barely above a whisper but filled with determination. "Iris is... she's very good at this." Her cheeks colour as she speaks, a blend of embarrassment and arousal painting her features.

"Do you want to see how deep Iris can take me, Jasmine?"

You lean back against the desk, your eyes locked on Jasmine's as you pose the question. The words hang in the air, thick with the promise of further depravity and the depths of pleasure that await. Jasmine's breath hitches, her gaze dropping to where Iris's lips are still wrapped around your dick, the sight leaving her both flustered and intrigued.

"I... I don't know, Draco," Jasmine stammers, her eyes wide with a mixture of trepidation and curiosity. The potion's influence stirs within her, urging her to explore, to learn, to indulge in the forbidden knowledge that lies before her.

Iris, sensing the unspoken challenge, pulls back slightly, maintaining just the tip of your dick in her mouth as she looks up at you for permission. You nod, granting Iris the silent approval she seeks. With a practised ease, she begins to take you deeper, her lips sliding down your shaft till she has your cock all the down her throat, while Jasmine watches, her eyes growing wider with each passing second. The room fills with the wet sounds of Iris's ministrations, punctuated by your low moans of pleasure.

Jasmine's hand flutters to her chest, as if to steady the rapid beating of her heart. She is captivated, her attention completely focused on the spectacle before her. The potion's influence is evident in her dilated pupils and the slight parting of her lips, mirroring the openness of her mind to the scene unfolding.

"Do you want to take over Jasmine? Do you think you've learned enough to copy Iris?"

The words hang in the air, a mix of challenge and encouragement. Jasmine's eyes flicker from Iris to you, her expression a blend of uncertainty and determination. The potion's effects are clear; she's caught in a whirlwind of curiosity and desire, and the nature of the act only serves to heighten her interest.

"I... I can try, Draco," she says, her voice shaky but resolute. She swallows hard, her gaze lingering on Iris, who has pulled back to give Jasmine room. The older Potter sister offers a supportive nod, her arousal evident in the flush of her cheeks and the heaviness of her breath.

You watch as Jasmine positions herself, mimicking Iris's stance. Jasmine takes a tentative lick. She bites her lower lip, a sign of concentration as she attempts to replicate Iris's experienced movements. Her first kiss is hesitant, her tongue sliding gingerly along your length, but as she continues, her confidence grows, each motion becoming surer than the last.

Iris watches with an approving smile, her hand drifting to her thigh, tracing slow circles through the fabric of her skirt. The sight of her sister's exploration seems to affect her, her breath hitching ever so slightly as she observes.

"That's it, Jasmine," you encourage, your voice low and husky with arousal. "Just like that. Remember what you've learned."

Jasmine nods her focus solely on the task at hand.

Jasmine's eyes flicker up to meet yours, a mixture of nervousness and eagerness playing across her face. Her hands tremble slightly as she reaches out to grip the base of your shaft. Her fingers feel cool against your heated skin, and you can see her taking a deep breath to steady herself before leaning forward.

Her lips part, and she takes you into her mouth, her movements awkward but earnest. The warmth of her mouth envelops you, and you can't help but let out a low moan of pleasure. Her eyes widen slightly at the sound, and you see a flicker of pride in her gaze. She starts to bob her head, her movements still unpracticed but quickly improving as she mimics what she's learned from watching Iris.

Iris, for her part, watches the scene unfold with a quiet intensity.

Iris catches your gaze, her eyes sparkling with understanding. She moves with a quiet grace, coming up behind Jasmine, who is still preoccupied with her new task. Iris's hand traces a path down Jasmine's back, slipping under the fabric of her robes and boxers. Her fingers dance along the waistband before delving lower, into the warm, inviting space between Jasmine's legs.

Jasmine gives a start as she feels Iris's touch, her mouth momentarily pausing in its motion. But the potion's influence, combined with the new sensations, only serves to embolden her. Iris's fingers dance across Jasmine's clit, coaxing a soft whimper from her as her body instinctively arches into the touch. Iris's fingers continue their exploration, sliding through the slick wetness they find. Jasmine's breathing hitches as Iris slips a finger inside her, her mouth resuming its task with renewed vigour. The sensation of Jasmine's mouth and Iris's fingers working in tandem sends jolts of pleasure through you.

"That's it, Jasmine," you say, your voice strained with the effort of maintaining control. "Just like that."

Jasmine's eyes flicker up to meet yours, and you can see the potion's influence in the glazed, hungry look in her eyes. She's caught in the throes of the potion's magic, her body and mind responding to the sensations.

You lean back against the desk, your eyes locked onto Jasmine's. The flickering torchlight casts a warm glow on her flushed cheeks and tousled hair. You let your gaze wander over her, taking in the way her robes have slipped off her shoulders, revealing the plain t-shirt underneath, stretched tight across her chest.

"You're doing so well, Jasmine," you purr, your voice echoing softly in the dimly lit room. "I can tell you're enjoying this, enjoying the way I fill your mouth." Her cheeks darken at your words, but she doesn't pull away. Instead, she seems to lean into the praise, her movements becoming more confident, and more deliberate.

"Look at you," you continue, your tone thick with desire. "So innocent on the outside, but such a quick learner. You were made for this. You like Iris's fingers in you?"

Jasmine's eyes widen slightly at your question, her mouth momentarily stilling around you. The potion's influence wars with her natural reserve, the dual forces visible in the conflict playing out across her features. Iris, attuned to both your desires and Jasmine's responses, pauses in her ministrations, her fingers remaining still within Jasmine, awaiting her answer.

"Answer him, Jasmine," Iris whispers, her voice barely above a breath, yet it carries an undercurrent of command that the potion has instilled in her. "Do you like my fingers inside you?"

Jasmine swallows, her throat bobbing, and for a moment, the only sound in the room is the crackling of the torches. Then she pulls away and answers. "Yes."

"This should be something a dad teaches his baby girl, does this make you your Daddy Jasmine?" you taunt.

The words hang in the air, a deliberate provocation designed to push boundaries and test the depths of the potion's influence. Jasmine's eyes flicker with a mix of shock and intrigue, her lips parting in a silent gasp as she processes the implications of your statement.

Iris, ever observant, senses the shift in the room's atmosphere. Her eyes dart between you and Jasmine, a hint of a smirk playing on her lips as she realizes the game you're playing. She withdraws her fingers from Jasmine, the sudden absence making Jasmine whimper softly in protest.

"Is that what you want, Jasmine?" Iris asks, her voice laced with mischief. "A Daddy to teach you all the naughty, forbidden things?" Jasmine's cheeks flame with embarrassment, but her silence is telling. Jasmine's eyes flicker between you and Iris, the silence in the room growing heavy as she grapples with the implications of the question. Her lips part, then close, then part again, as if she's trying to formulate a response that won't betray her conflicting emotions. But the potion is at work, unravelling her inhibitions one strand at a time.

"Do you, Jasmine?" you press, leaning forward, your voice soft but insistent. "Do you want me to be your Daddy, teaching you everything you need to know? Guiding you, correcting you?"

Iris giggles softly, her hand moving to Jasmine's thigh, gently squeezing. "Maybe you need a firm hand, Jasmine," she suggests, her confidence blooming under the influence of the potion.

Jasmine's eyes lock onto yours, the conflict within her giving way to a newfound resolve. She swallows hard, her throat working visibly, and then she nods. "Yes," she whispers, the word barely audible but heavy with meaning. "I want... I want you to be my Daddy."

Iris's hand tightens on Jasmine's thigh, her eyes gleaming with triumph and anticipation. "That's a good girl, Jasmine," she purrs, her voice a sultry whisper in the dimly lit room. "Now, show Daddy how much you appreciate him."

Jasmine's gaze drops to your lap, and she licks her lips nervously before leaning forward, her mouth open. The scent of your arousal fills her nostrils, the potion heightening her senses and driving her onward.

The soft wetness of her mouth encases you as she slowly takes you deeper. Iris watches, her free hand slipping beneath the hem of Jasmine's shirt, teasing the skin underneath and increasing the arousal coursing through her. Jasmine squirms, caught between the new sensation of your flesh in her mouth and the skilled touch of Iris's fingers.

Your hand finds its way to Jasmine's hair, fingers gently carding through the soft strands. A silent encouragement that makes Jasmine shiver. As Jasmine's lips glide along your length, her gaze flickers up to meet yours, seeking approval, a silent plea for guidance in this uncharted territory. You give her a small nod, a silent affirmation that she's doing well, that she's pleasing you.

Iris, ever the eager participant, leans in closer to watch Jasmine's technique, her eyes wide with fascination and arousal. She whispers encouragement, her voice a soft cadence in Jasmine's ear, punctuated by the wet sound of Jasmine's ministrations.

"Good girl, Jasmine," Iris murmurs, her hand now openly caressing Jasmine's side, her touch leaving a trail of goosebumps in its wake.

"Such a good cock sucker for Daddy."

Your words hang in the air, a tangible affirmation that resonates with the potion's influence. Jasmine's eyes flicker with a mix of pride and arousal at your praise. The title 'Daddy' seems to cement her submission, a role she's embracing with every passing moment.

"Thank you, Daddy," she murmurs, before she takes you back in her mouth and redoubles her efforts, her mouth moving with more confidence, her tongue exploring your texture and taste.

Iris, the observant student, takes note of Jasmine's technique and your reaction. She files this information away, eager to please you just as well, if not better. Her hand slips back inside of Jasmine pumping away in rhythm to Jasmine's ministrations. Iris's breath hitches as she watches Jasmine's transformation, her arousal growing in response to the scene unfolding before her. She bites her lower lip, her gaze flickering between your face and Jasmine's bobbing head. Her free hand finds its way to her thigh, mirroring her earlier touch on Jasmine, but this time it's her skin she's caressing.

"Daddy," Iris says, her voice soft but filled with a need that matches Jasmine's. "May I...?" She trails off, her hand inching higher, her eyes dark with desire."Yes, Iris. Show Jasmine how much you want to please me."

Iris's eyes light up at your permission, a soft gasp escaping her lips. Her hand moves with deliberate slowness, sliding up her thigh and disappearing beneath the fabric of her robes. Her movements are echoed in the rhythm of her other hand, which continues to caress Jasmine, encouraging her to pleasure you further.

Jasmine's focus remains on the task at hand, her mouth moving with increasing confidence, driven by the potion's effects and the praise from her 'Daddy'. The sound of her name, whispered like a mantra by Iris, spurs her on, a tangible sign of her submission and the bond forming between the three of you. Iris's breath hitches as her fingers find their target beneath her robes. The sensation of her touch, combined with the visual feast of Jasmine pleasuring you, sends waves of heat coursing through her. She squirms, her lips parting in a silent moan as she matches the rhythm of her hand beneath her robes with the motions of Jasmine's head.

"Oh, Jasmine," Iris whispers, her voice trembling with arousal. "You're doing so well, just like that. You're such a good girl for Daddy." Her words are a soft melody, a testament to the dynamic unfolding before you.

Jasmine's eyes flicker up to meet yours again, her gaze filled with burgeoning confidence and the desire to please.

With a firm grip on the back of Jasmine's head, you guide her further down onto your shaft. Her eyes widen slightly, but she doesn't resist. The potion's influence is clear; she's more willing to explore her limits, to please you in every way she can.

"Relax, Jasmine," you instruct, your voice steady and commanding. "Breathe through your nose and let it happen."

She follows your command, her body yielding to the intrusion. There's a moment of hesitation, a brief struggle as her body fights against the natural gag reflex, but then she relaxes, and you slide deeper into her throat. The sensation is intense, a warm, tight embrace that sends shivers of pleasure through your body.

Iris watches, her eyes wide as her fingers pump into herself and Jasmine. The sight of Jasmine taking you so deeply, the audible gulp as she swallows around you, sends a jolt of arousal through Iris. She's captivated, her pleasure heightened by the spectacle. Her breath comes in short, sharp gasps, her hand moving with increased urgency beneath her robes.

Meanwhile, Jasmine, with your guidance, is finding a rhythm, her throat constricting around you with each shallow thrust. Her eyes water slightly, but there's a fiery determination in her gaze, a desire to satisfy you that outshines any discomfort. As Jasmine adjusts to the sensation of you in her throat, her initial apprehension fades, replaced by a focused determination. Her hands grip your thighs, fingertips pressing into you as she steadies herself. With each shallow thrust, she takes you a little deeper, her throat working around your length.

Iris, entranced by the scene unfolding before her, matches her rhythm to Jasmine's. Her hand moves in sync with her sister's bobbing head, her breath hitching with each gasp and gulp from Jasmine. The sound of their shared pleasure fills the room, a symphony of soft moans and the rustle of robes.

"That's it, Jasmine," Iris encourages, her voice breathy and full of desire. "Show Daddy how good you can be."

As the pleasure builds to an unbearable crescendo, you give in to the overwhelming sensation. With a final, deep thrust, you release into Jasmine's throat. The warm, pulsating waves of your climax fill her mouth, and she instinctively swallows, her eyes wide and locked onto yours. The potion's influence ensures her compliance, but the flicker of surprise in her gaze is genuine, a testament to the intensity of the moment.

Iris, watching intently, bites her lower lip to stifle a moan as she reaches her peak, her body shuddering with the **** of her release. The sight of Jasmine swallowing, the knowledge of what she's just done, sends aftershocks of pleasure through her.

You pull out gently, allowing Jasmine to catch her breath. With a tender touch, you lift Jasmine from her kneeling position, guiding her onto the solid oak desk beside you. The cool wood against her skin elicits a slight shiver, but the warmth of your hands on her legs quickly dispels any chill. You spread her legs apart, revealing the dampness between her thighs, evidence of her arousal.

Jasmine's eyes are wide, reflecting a mixture of emotions—excitement, apprehension, and a deep, burning curiosity. The potion has done its work, stripping away layers of inhibition and leaving her eager to explore these newfound desires. She leans back on her hands, her chest heaving with each anticipatory breath.

"Looks like you left Jasmine unfinished there Iris, naughty girl. Crawl between her legs and lick her to an orgasm."

Iris, with a playful smirk and a twinkle in her green eyes, responds to your command with a nod, her long red hair cascading over her shoulders as she assumes a position between Jasmine's parted legs. She crawls forward, her hands sliding up Jasmine's thighs, pushing the black robe to the side revealing the damp fabric of her shorts.

"I think our little Jasmine needs some attention," Iris purrs, her gaze never leaving Jasmine's. With a swift movement, she hooks her fingers into the waistband of Jasmine's shorts and tugs it down, exposing her glistening centre. Iris inhales deeply, savouring the scent of Jasmine's arousal before leaning in and running her tongue along her sister's slit. Jasmine's body jolts at the first touch of Iris's tongue, a gasp escaping her lips. Her eyes flicker to yours, seeking reassurance, but also a silent plea for more. The potion has heightened her sensitivity, turning every lick and kiss into a surge of pleasure that radiates through her body.

Iris, relishing her role, explores Jasmine's folds with deliberate slowness, each stroke of her tongue designed to tease and tantalize. Jasmine's thighs quiver under the onslaught of sensation, her fingers clenching into fists on the desk's surface.

"Daddy," Jasmine whispers, her voice trembling with need. "It's... it's too much."

You chuckle softly, leaning back to enjoy the spectacle. Iris, undeterred by Jasmine's plea, increases her pace, her tongue darting and circling with practised ease. She looks up at you, her eyes shining with mischief and arousal, silently asking for your approval.

You give her a nod, a silent command to continue her ministrations. Iris obliges, her fingers joining her tongue in the exploration of Jasmine's most sensitive areas. She slips a finger inside Jasmine, then another, curling them in a beckoning motion while her tongue flicks against the bundle of nerves at the apex of Jasmine's sex.

Jasmine's body bows off the desk, a strangled cry torn from her throat as her orgasm crashes over her. Her inner walls clench around Iris's fingers, pulsating with the **** of her release. As Jasmine's orgasm subsides, her body goes limp, her breaths coming in short, ragged gasps. Iris slowly withdraws her fingers, giving Jasmine's sensitive flesh one last, lingering lick before sitting back on her heels, a satisfied smile playing on her lips.

"How did you like your lessons?" you ask. You pull Jasmine close, her body still trembling from the aftershocks of her orgasm. She looks up at you, her green eyes wide and slightly dazed. "Lessons?" she echoes, her voice barely above a whisper.

You chuckle, the sound rich and warm in the quiet room. "Yes, lessons," you repeat, your hand gently patting her head. "Did you enjoy them?"

Jasmine blushes, her gaze dropping to the floor. "I... I don't know," she admits, her voice barely audible. "It was... intense."

Iris, still sitting on her heels, grins at her sister's reaction. "Oh, come on, Jasmine," she teases, her tone light and playful. "You can't tell me you didn't like it. I saw the way you reacted." Jasmine's blush deepens, the redness spreading from her cheeks down her neck. She opens her mouth to respond, but no words come out. Instead, she buries her face in the crook of your arm, her body shaking with a silent laugh.

"Alright, alright," you say, a hint of amusement in your voice. "No need to be embarrassed." You glance over at Iris, who is watching the exchange with a smirk on her face. "What about you, Iris? Did you enjoy teaching?"

Iris's smirk widens into a full-blown grin. "Oh, I definitely enjoyed it," she says, her voice dripping with satisfaction. "And I think Jasmine enjoyed our lessons too, even if she's too shy to admit it."

You continue to stroke Jasmine's hair, your fingers gently massaging her scalp. "It's okay to admit you liked it, you know?" you say, your voice soft and reassuring. Jasmine peeks out from under her arm, her green eyes meeting yours. There's a moment of silence, broken only by the crackling of the fire in the hearth.

"I..." Jasmine starts, then stops, her gaze flickering to Iris before returning to you. "I did," she finally admits, her voice barely more than a whisper. "It was... different, but not in a bad way."

Iris claps her hands together, her grin widening. "See? That wasn't so hard, was it?" she says, her tone teasing. Jasmine gives a small nod, her blush still present but slightly less intense.

You look down at Jasmine, her face still flushed from her confession. "So do you want to continue our lessons Jasmine?" you ask, your tone casual yet laced with anticipation.

Jasmine's eyes widen slightly, and you can see the gears turning in her head as she processes your question. She glances at Iris, who gives her an encouraging nod. "I... I think I do," Jasmine says, her voice steadier now. "I mean, there's so much to learn, and I... I want to learn it from you."

A smile tugs at the corners of your mouth. "Good," you say, giving her hair one last pat before withdrawing your hand. "We can continue tomorrow. For now, why don't we head back? It's getting late."

Iris stands up, dusting off her robes. Jasmine nods, her eyes reflecting a newfound determination. She rises from the floor, her movements a bit unsteady, but with Iris's supportive arm around her waist, she manages to stand. The three of you gather your belongings, extinguish the candles, and make your way out of the room, leaving the warmth of the fire behind.

You reach out, your hands coming to rest on the curves of Iris and Jasmine's backsides. The gesture is possessive, a silent affirmation of the bond you share. "We should meet up on the seventh floor tomorrow to continue your lesson, Jasmine," you say, your voice firm yet gentle.

Jasmine's eyes flicker to yours, a mixture of excitement and trepidation in her gaze. She nods, her throat constricting as she swallows nervously. "Okay," she breathes out, the word barely more than a whisper. Iris, ever the supportive sister, gives Jasmine's hand a reassuring squeeze.

The three of you part ways in the corridor, each heading to your respective common rooms. The castle's stone walls echo with the fading footsteps, the air heavy with the promise of tomorrow's lesson.
