Challenge.

"Youre going to learn to be blindly obedient."

Daphne's words were a purr, sending shivers down Susan's spine. Her body was still sensitive from the intense orgasm, but the thought of serving Daphne in such a way only made her want more. She nodded eagerly, her eyes never leaving the blonde's.

"That's not all. Im going to make sure you know what a slut you are. Tomorrow you have a task. I want you to suck off ten boys."

The words hit Susan like a sledgehammer, her heart racing with excitement and fear. But she knew better than to protest. This was her role now, her purpose in the castle of lust. "Yes, Mistress," she murmured, her voice thick with lust.

"Not you Luna." Daphne stroked her girlfriends hair. "Youre on a strict pussy diet. Unless Potter wants to borrow you."

Luna's eyes sparkled with excitement at the thought of serving Harry, her pussy clenching involuntarily. "As you wish, Mistress," she whispered, her voice filled with eagerness.

The following day, Susan woke up with a mix of excitement and trepidation. The collar around her neck was a constant reminder of her task, and the anticipation of what was to come had her pussy already slick with desire. She made her way to the Great Hall, where the smell of breakfast filled the air and the sound of chatter echoed off the high ceilings.

Her heart raced as she scanned the room for potential conquests. She had never done anything like this before, but the memory of Daphne's praise and the promise of more filled her with a determination to succeed. Her eyes fell upon a group of boys sitting at a nearby table, their eyes lingering on her naked body as she approached.

"Good morning," she greeted them with a seductive smile, her voice carrying a hint of the submissive tone she had adopted. The boys looked at her with a mix of shock and excitement, their eyes traveling the length of her body. She could feel her cheeks heat up, but the thrill of the challenge overshadowed her shyness. "Who wants a blowjob?"

The first boy she approached was a Hufflepuff, his eyes wide as she knelt before him. He was already half-hard at the sight of her, and Susan felt a thrill at the power she had over him. She took his cock in her hand, feeling it pulse with life. The boy's gasp was music to her ears as she took him into her mouth, her tongue swirling around the head before she took him deeper.

Her mind was a whirlwind of thoughts, Daphne's instructions playing on repeat. She had to please these boys, had to show that she was a good little slut. The taste of him was new, a bit salty and musky, but it was a taste she quickly grew to crave. She sucked harder, her cheeks hollowing out as she took him in deeper.

The boy's eyes rolled back in his head as Susan worked her magic. His hands found her head, guiding her movements as he grew closer to his climax. She could feel his thighs tense up, his breathing growing ragged. It was exhilarating, knowing she had this power over him, that she could make him feel so good.

As she sucked, Susan felt a hand on her ass, squeezing gently. She looked up to see another boy, a Gryffindor this time, smiling down at her. He was already hard, and she could feel his cock pressing against her cheek. She didn't miss a beat, reaching up to stroke him as she continued to blow the first Hufflepuff.

The boy's grip on her hair tightened, and she knew she had him. She bobbed her head faster, her cheeks hollowing out with each suck. His moans grew louder, and she felt his balls tighten in her hand. She knew he was close, and she wanted to make sure he came in her mouth, to show Daphne just how well she could serve.

With one final, deep throat, she felt the warmth of his cum fill her mouth. She swallowed eagerly, her eyes never leaving his. He groaned, his head falling back in ecstasy, his hand loosening in her hair. Susan felt a sense of pride wash over her as she pulled away, licking her lips clean.

The Gryffindor was next. He didn't need much coaxing, his cock already slick with pre-cum. She took him into her mouth, her eyes flicking up to meet his as she began to suck. He was gentle at first, his hands resting on her shoulders, but as she grew more confident, she felt his grip tighten.

Susan's mouth was a warm, wet heaven around his shaft, her tongue swirling and teasing the sensitive spots she had learned from Daphne. He moaned, his hips bucking slightly, and she knew she had him. She took him deeper, her throat tightening around his cock as she took him all the way in.

The other boys at the table watched with a mix of envy and desire, some of them shifting uncomfortably in their seats. She could feel their eyes on her, their own arousal palpable in the air. It was intoxicating, this power she had over them, and she reveled in it.

With a final, **** thrust, the boy came, his cum spurting down her throat. Susan swallowed greedily, her eyes never leaving his. The look of pure ecstasy on his face was all the reward she needed.
