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 giggles and then replies, "Oh silly! No need to worry about that. I just want a nice, thick... toy for my mouth." She pauses for a moment before leaning in even closer, her breath tickling your ear as she whispers, "You can choose what size you'd like it to be..." Her hand begins tracing circles on your stomach, teasingly moving upward towards your crotch.

Her eyes widen in surprise at the size of your erection as you show it to her. A slow, knowing smile curls on her lips and she licks her own before saying, "Oh... well if it isn't a nice big one..." She tilts her head to the side, studying it carefully for a moment.

"You know what? Why don't you show me just how big you really are?" Sumi suggests, stepping back and motioning for you to follow her. She leads you over to one of the stalls and kicks the door closed behind them, latching it for privacy.

With an eager grin, she motions for you to stand between her legs as she leans against the stall door, propping herself up with one hand on the wall. Her other hand slides down to your crotch and roughly yanks down your pants, revealing your huge cock bobbing freely in front of her face. Sumi lets out a low moan at the sight of it, licking her lips before leaning forward and taking as much of it into her mouth as she can handle.

Her eyes close in pleasure as you fill up her mouth, feeling the weight of your enormous cock pressed against the back of her throat. She begins bobbing her head up and down eagerly, moaning around you as she takes you deeper and deeper with each thrust. Her hand begins to move in rhythm with her mouth, stroking your length as she sucks on you like a hungry beast.

As you start thrusting into her mouth, Sumi lets out a moan of pleasure that turns into a hungry growl as she feels your cock twitch against the back of her throat. Her body shudders with desire and anticipation, eager for more of you deep inside her. She sucks harder, stroking you expertly, doing everything she can to keep up with your pace.

Her breasts press firmly against your chest, their weight adding to the sensation as she continues to bob her head furiously up and down on your shaft. Her free hand reaches around, seeking out your testicles, squeezing them gently before moving higher, wrapping her fingers around your base, massaging you as she takes you deeper into her mouth with every stroke.

She purrs happily as she takes your cock deeper into her throat, feeling the pressure on her tonsils building up and making her wetter with anticipation. Her movements grow more frenzied, a wild look in her eyes as she tries to match your increasing speed. Sumi's breath comes out in ragged gasps, each one blending into moans of pleasure as the sensations overwhelm her. She has never felt so desired before and she knows that this is exactly what she needs, being used like a dirty little slut for someone else's pleasure.

As you reach your peak, Sumi feels the warmth spreading down her throat, pooling in her chest as you cum hard into her mouth. She swallows eagerly, drinking up every drop before licking her lips and grinning at you happily. Her body shudders with aftershocks of pleasure from the intense orgasm she's just experienced.

She grins slyly at you, "Well that was... interesting." She leans back against the stall door and adjusts her clothes, brushing away a few strands of hair from her face. "You know, if you're ever in the mood for more, I could always show you some new tricks." Her voice drips with promise, as she eyes your still-hard cock, thinking about all the ways she can pleasure it next time.

She grins wickedly at your words and steps forward, pressing her body against yours again. "Ohhhh, there's always more where that came from," she breathes huskily into your ear before trailing soft kisses down your neck. "Just think of all the naughty things I could do to you... If you really want me to." Her hand slips between your legs again, caressing teasingly at your aroused length through your boxers.

She tilts her head to the side, considering your words before grinning wickedly again. "Ohh, I like that idea," she purrs. "You want to put your big hard thing inside me?" She bites her lower lip thoughtfully, as if debating whether or not this is something she should allow. After a moment's hesitation, she nods slowly, licking her lips and smirking wickedly up at you. "Alright," she whispers, "but only if you promise to make me feel good too." She pushes you back against the wall, her breasts pressed tightly against your chest as she begins grinding her hips against yours suggestively through your clothes.

"Good boy," she purrs, her voice dripping with approval and lust. As you push your hips forward, hardening against her through your clothes, Sumi moans softly in pleasure. Her grind becomes more frantic, her breath hot on your neck as she arches into you. She bites her bottom lip to stifle the sounds of desire that spill from her throat, not wanting anyone else to hear them.

"Are you sure you want this?" she whispers teasingly, her voice rough with desire. "Because once I let you in... there's no going back."

Her breath hitches as you whisper those words into her ear, the simple confidence in your tone making her shudder with desire. "Then don't worry," she huskily replies, voice hoarse and ragged from suppressing her moans, "I promise to take care of every last bit of that for you..." Her hands slide down your chest, her fingers teasingly trailing across your stomach before slipping into the waistband of your pants. She tugs gently at first, but when she feels the fabric begin to give way, she grins wickedly and yanks harder, revealing the head of your cock free from its confines.

With practiced ease, she guides your cock towards her aching core, taking you inch by delicious inch as you both groan with pleasure. Her fingers dig into your shoulders, urging you on, demanding more contact as she grows ever closer to being fully impaled. Sumi's breath comes out in sharp gasps, each one whistling through clenched teeth as the head of your cock presses against her entrance, threatening to break through.

Her hips thrust upward suddenly, forcing herself down on you with a wet, satisfying sound. Your length slides easily inside her, filling her up inch by beautiful inch until she's completely taken, your broad shoulders pressed tightly against hers as you both grow even closer. She bites her lower lip hard, hissing through clenched teeth as she feels you stretching her limits, claiming her as yours.

Her body trembles with need and desire, every muscle tensing as she rides your cock, taking you deeper still with each powerful thrust. Sumi's fingers dig painfully into your shoulders, nails leaving tiny trails of blood behind as she loses control to the lust that consumes her, the overwhelming sensation of being completely owned by another person.

Her hips buck wildly against yours, seeking release from the relentless pleasure building inside her. "Fuck!" she cries out hoarsely, her voice muffled by your shoulder as she comes undone, her body shuddering uncontrollably around you. The tight muscles of her pussy clamp down hard on your cock, squeezing and massaging it in perfect rhythm with her orgasm as she writhes in ecstasy beneath you.

As her trembling subsides, Sumi meets your gaze
