Even If I Can't Permit It, I Still Want Sex
I want sex, but I can't give permission. "Haa... haa... D-do you understand?" What leaked from between my lips wasn't an explanation—it was a moan verging on a scream. My breasts, defenseless without the armor(?) of a bra, jiggled honestly. Gwang-tae must have felt it. How deliciously this soft, springy Kang Yeon-woo pudding shakes.
"Th-this part here? Teacher, this curve is so three-dimensional." Smooth~! Smooth!! His mouth begs for help with the problem, but with his eyes closed, he's rubbing his elbow against my breast, savoring its bounce. This isn't tutoring—it's just a breast resilience test.
"Um... so... this part is... Ah?!♥" His elbow... nudged my swollen, rock-hard nipple. I couldn't hold back anymore and let out a moan laced with a nasal whine. Gwang-tae's eyes flashed for a split second. As if he'd been waiting, he leaned in deeper and whispered, "Teacher, this problem is insane. But this formula... why does it feel so... squelchy?"
"?!!" I'm losing my mind. Now his hand has slipped right inside my top. Grab!! "Hngh!!" Squeeze~ Squeeze~ "Haa... haa..." My breasts overflow in his huge hands, too much to contain. My vision blurs. My head spins. Squeeze~ Squeeze~ His hands knead my breasts, then... Boing~ Boing~ Boing~ bounce them up and down like balls... Squish!! or grip them hard with his whole palm.
"Haaaang~!!♥" I'm going crazy. I want to shove his cock inside me right now. "Hua~ Teacher, this problem is so fun. Try it this way, try it that way~ I could play with just this one for a whole hour and lose track of time." His eyes are locked on my jiggling breasts.
"R-really? Hngh?! B-but... you're... obsessing over one problem... no progress!" "Ah?! Th-then... can we move to the next one?" Gwang-tae grabs my nipple in excitement. And then... twists it hard. Twist~! "Haaaaang~!!♥" "Teacher? Teacher? That moan was wild!"
"Kghhh!! B-but... instead of such... direct methods... hngh~♥ t-try... approaching the problem... more gently... hngh!!" "Oh, right. The problem. Yeah. But Teacher, the problem... it's gotten so hard. And it smells so good." Pinch~ Pinch~! "St-stop!! G-Gwang-tae~ haaang~ P-please... don't torment me like this~"
"Ha... ha... Right?? There's more problems too. Heh..." "?!" His hand slides down to my thigh now. I can barely breathe. Can't think straight. Every time that massive 'presence' bulging from his pants crosses my vision, an 8.0 earthquake hits my brain. I want to get impaled on it and scream right now. But... I grit my teeth. I gently pinch his hand on my thigh and push it aside.
"Haa... haa... G-Gwang-tae... enough playing~ Let's get back to calculus." "Nee~~??" A deep sigh bursts from Gwang-tae. Disappointment, frustration, betrayal. After teasing him in this short skirt and cleavage-baring top, guarding that final line to the death—how infuriating must I seem? Yeah, I know. This is a massive contradiction. But what can I do? Sex with my student Gwang-tae? A one-time slip-up, maybe. But he's not like those high school buddies I can just ghost. He's my sole income source—my high-paying tutoring student.
If I cross that line here... if I give in easily now, he'll demand insertion every lesson. Starts with just penetration, but soon it'll be blowjobs, creampies, anal—everything. He'll act like I'm his girlfriend, gleefully demanding it all. That's how guys work. Then why dress like this if I'm not gonna fuck him? Why let him grope me? ...I don't know. I really don't get myself. I tease, but I can't straight-up allow it. That's my situation right now. Time to change the title. I Can't Give Permission, But I Still Want Sex.
"Teacher. So, how do you solve this one? This problem feels like it has a... deep trap." Plunge!! "Hng?!!!" Is he insane?! I almost screamed. Shocked, I stared at Gwang-tae. His face beet-red, eyes glued to the workbook. His finger... shoved straight into my hole!! Slide~ Slide~ Squish~!!
"Whoa... the problem's so tight. Chewy too, kinda." "Hngh... G-Gwang-tae...?" "Whoa... it's soaked inside." Yeah... flood between my legs for ages. Panties were the dam holding it back, but Gwang-tae breached it and stirred the waters. Naturally, juices drip down his finger onto the chair below.
"Teacher. Truth is... this is my first time." "W-with a problem like this?" "Problem? Pfft? Yeah... the wrinkles and ridges inside feel so vivid. Warm... wet... and the grip. Wow~ It's alive~ Pulsing like it's breathing~ Squeeze~ Squeeze~ Just a finger and it's like this... if the real thing went in... you'd squirt nonstop from how good it'd feel."
"G-Gwang-tae... hngh..♥ D-don't say... things like that... to your teacher... hngh... n-no!" "Teacher. Let's be honest with each other now. You want it more than I do. That's why you dressed like this. This grip? Could pass for virgin. It's sucking my finger, won't let go. Say it quick. Teacher. You want it, right?" His hot breath tickles my nape, and my core surges, spilling more hot nectar. I held out to the end. I won't permit it... unless you force it.
Yeah. I know. Cowardly. But consenting purely vs. reluctantly? Worlds apart. That's what makes it a "mistake." ...I've become such a dishonest, twisted woman. "G-Gwang-tae..." "Yes, Teacher. I'm ready!!" "St-stop. No more. Really." "Yes?!!" Second rejection already. He might give up and leave. But... not now. He's already leaking precum everywhere—stopping here? Like flipping over a full feast yourself. Balls'll burst. I know he won't quit.
"Fuck..." His voice drips rage. "When the problem won't solve... gotta force it through!" Thrust!! "Guh?!!" Gwang-tae's finger plunges deeper without mercy. Scraping my inner walls, now it prods my cervix. Press! Press~!! Press~~!! "Haang~ Haang~ Haaaang?!!" Pleasure like screaming neurons blasts up my spine.
"Teacher? Feels good? Good?? Say it quick. Say you love it. Say you want it~!" "Haaaang~!! G-Gwang-tae... st-stop~ Please. W-we're teacher and student~ Hngh!♥" "Oh yeah? Guess I got no choice!" Stir~! Stir~! Squish!! His finger thrashes inside my pussy like it's trying to widen it. Nails scrape walls, grabs and shakes the whole thing.
"Kaaaaah~! N-no... Gwang-tae, not there... haaak!! S-sorry. I... I was wrong!!" Obscene friction echoes in the quiet room. Every assault on my womb arches my back like a bow. "Too late for apologies. Earlier one finger had you squeezing so tight~ Now you need more, huh."
"Ah... ang??" "Alright, second finger incoming~" "N-no..! Two's too much~! No!!" "Liar~ Your pussy's drooling like crazy, begging for more." Gwang-tae smirks and shoves the second finger in rough. The tight entrance stretches to tearing— I nearly black out. "Kaaaaaaaah~!!" "Two too much? Won't go in easy."
"G-Gwang-tae... I... I was wrong. Forgive me now... kghk.." He freezes at my apology, staring into my eyes. "Teacher. I love you." "Ah...?" "Honestly, I was pissed. Learning you gave your virginity to some guy you weren't even dating. If that's how it is... give it to me instead."
"Gwa...ng-tae..." "Whatever. Even if it's a used workbook someone's solved already, doesn't matter. I wanna date you, Teacher. Hell, marry you." Sudden confession. His eyes burn with pure sincerity, no play. But... I can't. I'm not a "woman" officially. Middle school, high school—all boys' schools. Even my ID says male. It'll come out eventually. Love turns to hate when it sours.
"No, Gwang-tae... We can never date. Not that. I'd die first!" My firm refusal twists his face monstrously. Betrayal and fury pierce me. After groping my tits and fingering my pussy, saying "we can't date" would piss anyone off. "Why?! You like me too! That's why you're seducing me like this! Juices dripping here. So wet, and it's all lies?!"
His shout leaves me speechless. I answer only with the nectar soaking his fingers. "Sorry... Gwang-tae... Instead... instead..." "Instead what?" Tears well up. I wasn't gonna permit sex... "Y-you can... put it in."

"Teacher. Won't date me, but you'll give it once?" Gwang-tae's voice chills colder. Disappointment drips like his tone stabs my heart. "Fuck, you're such a cheap slut. Fucking a guy you won't even date?" "Th-that's not!!"
No time to retort—his face crashes down. Mmph!! Rough kiss. Lips smash, his hot tongue ravages my mouth. Not how you kiss someone you love. I squirm in shock, but his heavy scent and iron arms crush my resistance. My mind screams this is wrong, but tangling tongues tastes so sweet. Trembling, I grab his broad shoulders and accept the devastating kiss.
Calculus lesson over. Now... another lesson begins.
