The Overtime My Junior Left Behind

Wednesday brought no rain. There was no sound of water in the ceiling either. The umbrella stayed in the entryway, and the cup sat untouched in the sink. I left for work without putting either of them away. At the morning meeting Seo Yu-jin called me Assistant Manager and handed over nothing but the quote file. No text came from Jeong Ha-neul. Only the cup remained at home.

My junior was Kim So-yul. Twenty-seven. The youngest on the General Affairs team. Her voice was small and soft. She read every email twice before she sent it, and when she was scolded, her ears reddened first. She was short, and she always tucked her hair behind her ears. She buttoned her blouse all the way up to the collar. Her steps were quiet, and when she gave a report she looked at the edge of the papers, not at my eyes. Even so, when we passed in the hallway, she was the one who bowed first. Today that bow lasted longer than usual.

Only two of us were working overtime. Nine o'clock. The lights on the other floors were already out. So-yul dropped a clipboard while handing me the materials. Reaching down to pick it up, her hand brushed my knee. She didn't pull it away at once. Her palm pressed once against my trousers, then dropped.

"I did it on purpose, Assistant Manager. Hah. I'm not going to apologize. My hand touched you there and—mmn—my stomach went tight."

"I knew it. The clipboard was an excuse. You wanted to press my thigh. Ngh—I'm already hard."

"Yes. I heard about the Team Leader and the umbrella in the hallway yesterday. The upstairs neighbor, too. I'm not in either of those stories. I stayed today because—hah—I wanted you inside me. Even if my voice shakes, please don't pull out."

Her ears were red. Her voice didn't waver; only her breath was wet. I turned the chair. So-yul stood between my knees. The hem of her skirt brushed the back of my hand.

"I don't want the office. There are cameras. The restroom—the last stall in the women's room. Follow me now. Please leave the light on. Ahn... I'll watch. Yours, with my mouth first."

Only the emergency lights were on in the hallway. So-yul walked ahead so her heels wouldn't make a sound. When the restroom door opened, it smelled of detergent and damp. The last stall. She went in and slid the latch. It was narrow. She put the toilet lid down and sat me on it, then turned her back to the door and knelt. The tile was cold enough to raise goosebumps on her thighs.

"You can look. Hah. I'll talk with my breath mixed in. Mouth first. Even if I'm clumsy, please don't pull out. If my teeth graze you, I'll soothe it with my tongue. Mmn."

I lowered the zipper. I was already hard. So-yul pressed it once with her palm and let a drop of spit fall on the head. Her tongue circled the tip, and her lips closed around it. She kept her teeth tucked behind her lips. She took half of me, hollowed her cheeks, and sucked. Spit ran down the shaft and wet my balls.

"Mmph, it's hot. Hah, hah. The smell is strong. I can't take it to my throat yet. I'll swallow just half. I'll keep my tongue underneath. Mmn, breathe loud, Assistant Manager. If I hear that, my underwear gets wetter. Ahn."

"Ngh, your tongue's soft. Keep it right there. Hah. Tighten with your cheeks. Don't wipe the spit. Your lips are stuck to the head. Hah."

So-yul bobbed her head at a steady pace. One hand gripped the root and stroked out of time with her mouth. Her moans leaked through her nose—mmph, hah, mmn. She lifted her eyes to check my face. They were wet. She had opened them to taste me.

"It's pulsing at the tip. Hah. Tell me when you're going to come. I'll swallow. Please don't get it on my face. Today I'll take it in my throat. Mmph, ahn, hah."

"I'm coming. Nnngh, hold it just like that. Hah, I like your throat squeezing. Cum."

I came in her mouth. So-yul swallowed twice, then dragged her tongue over the slit as if to press out whatever was left and take that too. She didn't wipe the corner of her mouth. She looked at me.

"Hah, it was salty. I swallowed. My lips are shiny. Now please touch me. My underwear—you check how wet it is, Assistant Manager. Mmn."

She stood and hiked her skirt to her waist. The center of her white underwear had soaked through dark. She set one foot on the toilet lid and spread her legs. When I pulled the cloth aside, the flesh was wet and open. The ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠tip of it was small and hard. I pushed the flesh up with a finger, and So-yul grabbed the door handle.

"Ahnk, don't press it directly. Push the flesh. Hah, hah. I can make noise. There's nobody on this floor. Mmn, there—please get spit on it. Make it slippery. Aahn."

"Hah, the cloth is stuck to the inside. It's hot. Ngh, if I put a finger in, I think you'll gush right away."

I put one in. She clenched around it at once. Tight, and the front wall was ridged. I waited until she nodded before the second. When I curled them and pressed the front wall, her knees shook.

"Haaahn, that spot. Don't scratch—press. Aahn, it's aching under my stomach. I like it. Mmn, hah. Your thumb on top, too. Not fast. Steady. Ahnk."

I worked the front wall and the top together. The wet sound struck the partition and came back. So-yul set her forehead on my shoulder, her breath breaking and catching.

"I'm coming. Haaahk. I'll come once on your fingers. Then put it in. I decided I'd take it today. Standing, in this stall. Aahn, please don't pull out. Nnnn, hah."

"Clamp down. Hah, your slick's all the way to my wrist. I'm putting it in now."

Her insides squeezed my fingers. While the aftershocks were still in her, I shoved my trousers down to my knees. I was hard again. So-yul took it in her hand and set it against her entrance.

"It's big. Hah, it's hot. Just half first. I'll lower myself. For now, please move. Slowly. Ahn, even the tip touching me makes me shake."

"Hnn, only the tip's caught. It's hot. Hah, squeeze. Even halfway in, it won't let go."

Standing on the toilet lid, So-yul gripped my shoulders and lowered her hips. When half of me was inside, she bit my collar with her teeth. As she took the rest, her breath split in her chest. The stall was so narrow the stroke going out was short. I kept my hips against her and drove up as if I were scraping the front wall.

"Haaahk, it reaches the bottom of my stomach. Ahnk. Please lift the angle. There, mmn. Talk. Tell me what my inside feels like. Hah, hah, aahn."

"Tight. Nnngh, it's got me all the way to the root. Every time I pull back, the flesh follows. Hah. The partition's shaking. So-yul, you're so hot and wet in there it's making noise."

"Fuck me so it shakes. Aahn. Grab my nipples too. Inside the blouse—pinch them. Mmn, I like it, hah. Please say my name. So-yul. While I'm coming. Ahnk."

I undid two buttons of her blouse and slid my hand in. When I pushed the bra up, her breasts were small. I pinched a nipple, and she clenched around me once more. The sound of flesh hitting flesh bounced off the tile.

"So-yul. Hah. In front of the Team Leader you button all the way up, and in here you've swallowed me to the root. Nnngh. I'm fucking you with your underwear still soaked. Squeeze. Harder."

"Haaahk, that. Say it again. Aahn, I'm embarrassed and I'm clenching. I can feel it. Please don't pull out. Come inside. I'm on the pill. I'll take it in this stall today. Nnnn, deep. Hah, hah, aahn."

"I'm coming too. Ngh, you're squeezing so hard I can't pull out. I'm coming inside. Hah."

I drove in to the hilt and came. So-yul wrapped her arms around my neck. Her moan was a broken breath—haaahk, aahn, it's hot. The aftershocks made her insides twitch, and it took time to pull out. When I slipped free, cum ran down her thigh and dripped onto the rim of the toilet.

"Hah, hah. It came out. It's leaking. Before I wipe, please look one more time. How I stayed open because of you. Mmn, I'm ashamed, but I don't want to close."

I spread her entrance with my thumb and showed her what was spilling out. So-yul didn't look away. Only her ears were red. She sat me down again.

"Once isn't the end. Hah. I'm going to sit on your face. Please look from behind. Your tongue only on top. I'll match you with my hips. Ahn, it'll be hot."

With her skirt still hiked, she turned and climbed over me. She lowered her wet flesh onto my mouth. Cum and her slick mixed on my tongue. So-yul held the partition and rolled her hips in small motions. Her thighs clamped my ears.

"Ahnk, your tongue's hot. Please lick only the top. Hah, hah. Get spit on it. I like it. Mmn. Taste what you just came, too. I'm ashamed, but I don't want to take it away. Aahn, there, steady. Nnnn."

"Mmph, salty. I'll hold my tongue still. So-yul, grind with your hips. Hah, it's running all the way to my chin."

So-yul pressed down hard once. The second climax came as a spasm in her thighs. The sound stayed trapped in the stall—aahn, hah, I'm coming, Assistant Manager. She couldn't climb down. She braced a hand on my forehead. Her slick ran to my chin.

"Hah, my legs are giving out. But I still want it in. Hands on the tank, from behind. Now. Ahn, I'm already open."

She turned and set her hands on the toilet tank. When she lowered her waist, her underwear was rolled to one side. I stood behind her and pushed in to the root in one stroke. She was already open, so there was little resistance. Inside, she was hotter.

"Haaahn, it's deep. From behind, my stomach's being pushed. Ahnk. Please grab my hair. Hard. There's no mirror. You don't have to see my face. Just listen. Mmn, hah, aahn."

"Hah. Your ass is stuck to my stomach. Nnngh. Cum comes out every time I hit you. Tight. So-yul, shake while you're pressed to the wall."

I wound her hair around my hand and picked up speed. Every time flesh met flesh, So-yul cried out low. I didn't pull out. I came in her again. She dropped her waist lower to take it.

"Haaahk, I'm coming again. Aahn, inside again. Nnnn. It's hot. Hah, hah. My name, just one more time."

"So-yul. I'm coming inside. Ngh, squeeze. Take it."

"Hah. It went in. Please pull out. My legs gave out. Mmn, I'll put it in my mouth one more time before I go."

When I pulled out, two loads soaked her thighs and dropped onto the tile. So-yul didn't wipe. She sat me on the toilet again. She knelt and lifted what was still soft and limp into her hand. Her tongue worked the groove under the head as if she were digging into it. The taste of cum was still there, salt mixed in. When I was half-hard again, she opened her mouth and swallowed half.

"Mmph, it's getting hot again. Hah. Only to the entrance of my throat. That's my limit today. Mmn. I'll stroke the root with my hand. Ahn, out of time with my mouth. You can hold me. Just match the rhythm."

"Hah. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠What was soft is getting hard in your mouth. Nnngh. Press harder with your tongue. So-yul, your spit tastes salty."

So-yul pressed the head with the flat of her tongue and shook her head. Spit strung out again. When it started pulsing at the tip, she held her mouth still. I moaned low and came in her mouth. She gathered it with her tongue and swallowed, then sucked the slit until she had the last drop.

"Hah, it was salty. I swallowed. I'll leave without wiping my lips. I'll taste it in the elevator. Mmn. But against the wall, just once more. From behind."

The last stall was the same as we'd left it. So-yul pinned her skirt at her waist and set both hands on the tile. When she lowered her hips, her underwear rolled aside and her labia showed. The cum that had leaked was still glistening. I rubbed the spot with the head, and the tip sank in at once.

"Haaahn, the wall is cold. My nipples are stuck to it. Ahnk. I'm already open. To the root, in one go. Mmn, hah. Please talk more. Tell me what kind of slut I am."

"Hah. It goes in all at once. Nnngh. The youngest took me to the root in the last stall with her panties shoved aside. Tomorrow you'll button up to your collar and remember this taste, won't you. Squeeze."

"Haaahk, that. Aahn. It's echoing under my stomach. I'm coming. Please come inside again. I'm on the pill. Please stay deep. Nnnn, hah, hah, aahn."

"Coming. So-yul. Inside. Hah, take it."

I drove in to the hilt and came. There wasn't much; only the pulse lasted. So-yul scratched the wall as she went over. When I pulled out, her thighs were wet all the way down her calves.

"Hah, hah. Now I'm really going. I won't wipe. I'll just pull my underwear up. If it leaks in the elevator, I'll endure it. That's yours, Assistant Manager. Mmn. At tomorrow's meeting, don't look at these hands. If you look, I'll get wet again. On overtime days, I'll call you to this stall."

"All right. Tomorrow I'll keep my eyes on the papers. I won't forget how your lips taste."

The sound of her heels cut off in front of the elevator. I stayed in the stall and didn't press a tissue to the white mark on the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠rim. When I got home, I looked at the umbrella and the cup. Today the smell of restroom detergent had wedged itself between the two of them. The ceiling was quiet. I lay down without wiping my mouth. I decided that at tomorrow's ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠meeting I wouldn't look only at So-yul's buttons. If I looked, I wouldn't keep that promise. I already knew it.
