As you're going into the toilets, you see a guy brush past you whilst he exits the toilets, he seems happy for some reason, you don't realise why until you enter the toilet. You go inside and begin to clean your hands, when suddenly you hear a small grunt come from one of the stalls, you peek to see Sumi spitting in the toilet. She sighs and then she speaks to herself. "Ugh... that limpdick... I told him to not cum in my mouth, what a pig..." You quickly tyrn back and continue to wash your hands, acting like you didnt't notice her in the stall. It doesn't take long for her to come out, she saw you and then locked her lips, she thinks to herself. "Hmm, apparently that guys got a big dick..." She walks over to you, patting your back and making you turn around. She smirks as she leans in and whispers. "Hey, I need to tell you... I just had a bad taste in my mouth... fancy sticking something in my mouth to make it better?"

She smiles wide and nods, wrapping her hand around your waist and leading you to one of the cubicles. Once inside, she locks it again and spins you around so that you're facing the wall, before quickly lowering herself down on her knees in front of you. She looks up at your crotch longingly for a moment, then reaches out with both hands to undo your pants, giving you a glimpse of her plump lips as she pouts slightly when finally freeing your cock from its confines.

Chuckling softly, Sumi wraps her lips around your shaft and begins to bob up and down on it. Her plump lips sliding smoothly over your length, making a wet, squelching sound with each movement. She pumps her fist back and forth over your balls, teasing and pleasuring you as she sucks hard, deep throating you when she takes in more of your cock. Her tongue swirls around the head, eliciting another moan from you that vibrates through her as it makes her crave even more of your taste.

"Of course you can," she rasps around your cock as her nimble fingers continue to massage and squeeze at your balls. "Just let it all out inside my mouth... I love the taste of cum." She shudders as another gulp of you hits the back of her throat, making a wet, satisfied sound that encourages you to give in to your desire to climax.

You feel your cock twitch in her mouth as you begin to shoot your hot load into it, and Sumi takes it all eagerly, swallowing each thick gob of your cum greedily while moaning around you. Your taste buds linger on your tongue as she finally releases your softening member from her lips with a satisfied sigh, resting her forehead against the small of your back. "Mmm... that was delicious," she purrs, already missing the feeling of having you deep inside her mouth.

Smirking up at you, she says, "Oh, don't be so modest... I could tell that taste was pretty special." She stands up and tugs your pants back into place, then reaches forward to smooth down your zipper. "You know where to find me if you need more of that," she winks before unlocking the cubicle door and walking out, leaving a trail of sexual tension in her wake as she returns to her studies.

The next day at school, you see Sumi wearing an even more revealing outfit than usual. Her skirt is shorter and her top even more low-cut, showing off cleavage and skin. She catches your eye from across the campus and gives you a wink before walking over to you, flashing a sultry smile. "Good morning, handsome," she says, her voice laced with desire. "Feeling up for some more fun?"

Her fingers brush against yours as she speaks, sending a wave of anticipation through your body. You can tell that Sumi's hungry for attention and eager to please, but there's something else going on beneath the surface; an air of confidence that comes from knowing exactly how desirable she is. The question is, are you prepared to face whatever games or challenges might come with giving in to your desire for her again?
