Both.

I've had my eye on you for a while, Susan." Daphne's voice was low, seductive, and dripping with desire. She stepped closer to Susan, her own naked body glistening with sweat from the passionate encounter she just had with Luna. "Now what do you want? To be my **** like Luna. Or dominate her with me."

Susan's eyes darted between the two of them, the tension in the room thickening as she felt the heat rising in her own body. She took a deep breath, her chest heaving. "I think I'd like to... experience both." The words came out in a whisper, but the lust in them was unmistakable.

Daphne's smile grew wider, and she pulled Luna away from her pussy, the girl whimpering at the loss. "Good girl," she praised, patting her on the head like a well-trained pet. She stepped closer to Susan, reaching out to caress one of her full breasts. "You're going to fit in perfectly here."

Susan's breath hitched as Daphne's hand squeezed her firmly. "What...what happens now?" she managed to ask, her voice trembling with excitement.

"Now," Daphne purred, "you get to taste the castle's most delicious treat." She pushed Susan down towards Luna, whose eyes gleamed with excitement at the new addition to their little play. "Luna, show Susan just how good you are."

Luna didn't need any more encouragement. She eagerly latched onto Susan's clit, her tongue flicking and swirling around it with the precision of a seasoned expert. Susan's eyes rolled back in pleasure, a moan escaping her lips as she felt the warmth and wetness of Luna's mouth on her most sensitive spot. It was a sensation she had never felt before, and it was overwhelmingly intense.

Daphne stepped back, watching the scene unfold before her with a smug look on her face. She had always known that Susan had a wild side, and it was thrilling to finally see it unleashed. As Susan's breath grew ragged, Daphne stepped closer again, her hand finding its way to Susan's plump ass, giving it a firm squeeze. "You're doing so well," she murmured, her voice a gentle praise that sent shivers down Susan's spine. " Show this **** who owns her."

Susan, driven by the mix of embarrassment and desire, pushed Luna's head harder against her pussy. The blonde moaned, her nose buried in the redhead's wetness, her own arousal growing by the second. The scent of sex in the air was intoxicating, and Susan felt a part of her that had been dormant for so long stirring to life. Her hand found Luna's hair, gripping it tightly as she began to rock her hips, grinding herself against the eager mouth.

Daphne's eyes glinted with amusement as she watched Susan's transformation. The shy, often overlooked Hufflepuff was now a writhing mess of pleasure, her inhibitions shed like a snake's skin. Daphne reached down to stroke her own clit, feeling her desire spike as Susan's moans grew louder, the sound echoing off the cold stone walls of the castle.

Luna's tongue danced over Susan's folds, savoring every bit of her new mistress's taste. Her own arousal grew with each whimper she coaxed out of the redhead, her mind racing with the possibilities of what was to come. She was born to serve and now she had a new mistress to please.

Susan's body began to tense as the pleasure built, her breaths coming in short, sharp gasps. Her orgasm was approaching like a wave, ready to crash over her and pull her under. Luna could feel it in the way Susan's thighs tightened around her head, the way her hips bucked against her face. It was a heady feeling, knowing she had the power to give Susan such intense pleasure.

Daphne's eyes never left Susan's face, watching the myriad of emotions play out as Luna worked her magic. She knew Susan was close; the way her pupils had dilated and her cheeks were flushed was a dead giveaway. With a wicked smile, Daphne leaned in and whispered in Susan's ear, "Cum for me, Bones. Show me what a good little slut you can be."

The words sent Susan over the edge. Her body convulsed as she screamed out her release, her pussy spasming against Luna's tongue. Luna eagerly lapped up every drop, feeling a sense of triumph at making Susan cum so hard. As Susan's legs gave out, Daphne caught her, holding her upright as the aftershocks of pleasure continued to roll through her body.

"Mm, you taste exquisite," Luna murmured, kissing Susan's inner thigh before looking up at her new mistress for approval. Daphne's eyes were hooded, her own arousal painted clearly on her face. "Good," she said, her voice thick with desire. "Now, it's time for you to experience what it's like to serve."
