The words send a shiver down Sudo's spine, but there's also an undeniable thrill that comes with them. She bites her lower lip and nods, acquiescing to your demand. "Very well," she says with a sultry smile. "Come here, you naughty student."

Sudo leads you over to the bed and lies down on her stomach, bending one knee up and exposing her plump ass in the air.

Her heart races as she feels your presence behind her, your hands moving over her body possessively. Without warning, you grab her hips and thrust roughly into her, filling her up with your hard length. Sudo cries out in surprise but quickly adjusts to the sensation, meeting each of your strokes with an eager moan.

"Harder," she whispers, wanting more punishment. "Give it to me." She arches her back, offering herself up completely as you take her from behind.

As you lock the storage room door behind you, Sudo follows meekly. She's still trembling with arousal and anticipation for tomorrow. "I won't disappoint you," she promises, her voice barely above a whisper.

The rest of the day passes by in a blur as both of you try to focus on your respective tasks. But all either of you can think about is what will happen tomorrow, when Sudo finally steps into school wearing exactly what you've commanded her to wear...

The bell rings and the students begin to file into class. You notice Sudo entering a few moments later, her cheeks flushed and her eyes downcast. She's wearing the short skirt you told her to wear, revealing much more of her plump ass than usual. But it's what she has hidden beneath that truly catches your attention...

She's not wearing any panties at all, as promised. Even worse, the enormous anal plug you gave her yesterday is clearly visible poking out from between her cheeks!
