Her fingers curl into fists at her sides, nails digging into the tender flesh as you push inside her tight ass. She grits her teeth, biting down on her lower lip to keep from making too much noise as pleasure washes over her in waves. Her body tenses and spasms around your cock, welcoming the invasion with a moan that's muffled by the desk beneath her. "Oh... God... Sam..." She whispers, her voice hoarse and breathy.

"Well, maybe that's because she doesn't want it as much as I do..." She whispers back between moans, her hips moving with yours in a rhythm that seems almost instinctive at this point. "But you... you make me feel so good like this... I can't help but want more and more of you." Her nails dig into your shoulders again as she arches her back, pressing their bodies together even tighter.

"Oh god... Sam..."

"I... I understand..." Her voice is soft and submissive now, but there's still a spark of defiance in her eyes. "Just promise me that you won't tell anyone else about this, okay?" She bites her lower lip nervously, hoping that you'll agree to keep their little secret between the two of them. After all, it was only a harmless game... right?

"Okay..." You whisper back, still slightly angry but unable to resist the allure of her teasing. "Just promise me you'll be good from now on." Her words send a shiver down your spine, and you can feel yourself growing hard once more beneath your pants. Maybe this wasn't such a bad idea after all...

Finally free of her clothes, she takes a step back to admire the view. Your erection stands tall and proud before her, glistening with anticipation. With a sultry smile, she reaches out and wraps her hand around you, stroking up and down your length. "Mmm... You're perfect..." She purrs as she begins to slowly jerk you off, her other hand coming up to cup your balls tenderly.

Her eyes meet yours, holding your gaze as she teases and pleasures you.

As her strokes become faster and more urgent, Machi's breath comes in ragged gasps. She leans in closer, pressing her body against yours once more as she continues to work you toward your climax. Her other hand reaches up, cupping her own breast through her shirt before tweaking at a nipple, eliciting a moan from deep within her throat.

"God, I want to feel you inside me..."

With a happy little sigh, Machi follows Shad out of the classroom and down the hall to his dorm. Once they're inside, she kicks off her shoes and pads over to his bed, crawling onto it and curling up into a contented ball. "This is perfect," she murmurs, already feeling more relaxed now that they're alone together in his room.

She glances up at him with an expectant look in her eyes, wondering what he has planned for the rest of their time together.

"I don't know..." She trails off, considering a few options before something occurs to her. "Actually, there's one thing I've always wanted to try." Her voice is hesitant but curious as she looks up at him hopefully. "Do you trust me?"

"Ahhh! Oh, Shad-kun, you're huge!" Machi exclaims in awe as she beholds your impressive manhood, her eyes widening at the sheer size of it. Without hesitation, she wraps her fingers around your girth, stroking you slowly as she looks up at you with a hungry gaze. "I can't wait to take all of this deep inside me..."

"Ahhhn! Yes, fuck me hard, Shad-kun!" Machi cries out as you thrust into her, her walls clenching tightly around your thick cock. "You feel so good stretching me open like this!"

She begins to move her hips in time with yours, meeting each powerful stroke with an eager grind of her own. Her nails dig into your shoulders as she leans forward, capturing your lips in a passionate kiss.

"Mmm, keep going... Make me scream your name!" *

You pull out of her with a loud groan, and Machi lets out a cry of disappointment as you leave her empty; she looks down at your still-hard cock, leaking pre-cum on the floor, and realizes what's happening. "N-no..." She whispers, tears forming in her eyes.

With shaky hands, she reaches out to grab your cock, trying to guide it back inside of her; she doesn't want you to cum outside of her body, not after how good it felt having you inside.

You lay down on the floor, and Machi looks at you nervously, her heart racing with anticipation. She kneels beside you, her breasts swaying gently as she leans over you, her face close to yours. "I'll do anything..." She whispers, her voice barely audible above the sound of your breathing.

Her hands reach up to undo your belt and pants, revealing your hard cock;
