Jogging Club with the Professor
A full week had already passed since Jaehun and his mother returned from their trip to Europe.
I woke before dawn and rummaged around for my workout clothes, moving with quiet urgency. Today was jogging-club day. Over break, a few of us who actually got along had decided we should do something active together, and a little exercise group was born — me, Jaehun, a couple of other friends, and our department professor.
It had started as just us students. Somehow Professor found out and asked if she could join. When a professor says she wants in, you don't exactly refuse. So the roster became five, Professor included. We agreed to meet up now and then for a run. Today was the first session.
I got up at five, knocked back a rough breakfast of bread, stuffed a change of clothes and a couple of energy bars into my bag, and left the studio before the sun was even up.
Halfway down the stairs I heard the scrape of a broom from below. My landlady. Forty-seven years old, widowed, kids all grown and married off — she lived alone in the rooftop owner's unit and managed the building herself. Every morning before dawn she personally swept every flight of stairs.
"Good morning."
I greeted her as she worked.
"Oh, Minwoo. Where are you off to this early?"
Her face was still soft with sleep. She'd shoved her wavy hippie-perm hair to one side and pinned it roughly with a big clip. Even at her age there was something naturally sexy about her — a quiet, unforced allure that slipped through without trying.
"Just heading out for a morning jog."
"Really? Look at you, so diligent. Youth really is wasted on the young. I should exercise more myself."
She laughed and gave my arm a light swat. As her hand dropped, her full breasts swayed inside her loose homewear. It was early; clearly no bra underneath.
"You should try jogging or hiking, ma'am. There are mountain clubs and all kinds of groups these days."
"At my age I'd just wreck my knees and come home miserable. Better to hop in the car, go for a drive, and look at the autumn leaves."
The nicest car in the building's lot was hers — barely driven, always collecting dust in the far corner.
"Haha. That does sound nice. Honestly, I don't love working out either. It's just hard. Driving around, eating good food — that's the real dream."
I matched her tone with a deliberately mischievous grin.
"Right? Heehee. You get it, Minwoo. The foliage really must be beautiful right about now."
"You should go with some friends. The weather's perfect for getting out."
"I don't have friends who are free. Everyone's wrapped up in their husbands and kids… Aigoo. Once you hit this age, even hanging out with friends gets hard."
I nodded. For someone who owned a whole building, she looked lonely. It tugged at something in me.
"My son's about your age. He's living near his school out in the provinces, and he never comes home. He's all grown up now — doesn't need his mom anymore. Aigoo."
She gazed out at the still-dark morning and let out a bitter sigh. Her small back looked so forlorn.
"He's probably just busy. College kids these days are slammed. Don't take it to heart."
"Still… aigoo. If only he were as thoughtful as you, Minwoo. Right?"
She pouted a little and ran her hand down my arm.
"Haha. Then just think of me as your son. You're about the same age as my mom anyway."
Her face lit up.
Maybe the kid who actually showed up every day and treated her kindly could ease her loneliness more than the real son who never came home. She never said a word when my rent ran late, and she sometimes brought over vegetables and side dishes from the little garden beside the building. I wanted to be of some small use to her in return.
"Should I? Make you my son, Minwoo?"
"Sounds good. Mom. Haha."
"Mom? Heehee, I like that. Oh my, I've kept you too long. Anyway, go have a good workout, son."
She patted my back and beamed. I said goodbye, headed down to the parking lot, got in my car, and drove toward the meeting spot — Gangbyeon Park.
The cold air pouring through the window stripped the last dregs of sleep from my head. The park was only about twenty minutes away. Before long I pulled into the riverside lot.
I could see my friends in the distance. I parked and walked over at an easy pace.
"Yo. Hurry up."
Jaehun waved me over. Beside him the others were already doing warm-up stretches in loose rhythm.
"Where's Professor?"
"She'll be here any second."
The words were barely out of his mouth when a pair of headlights swept across us and a car rolled into the lot. A top-tier imported sedan parked, and Professor stepped out.
Professor Lee Su-jin. The youngest professor at our school, and the one students actually felt comfortable talking to. She'd made professor at thirty-five, and even her way of speaking set her apart — no wasted words, every decision calculated and certain. Every time I saw her, the sheer charisma made me look up to her.
"Professor! Good morning!"
The guys bellowed their greetings before she'd even closed half the distance. It wouldn't affect anyone's grades, but watching their bodies react on autopilot still made me snort.
"Oh my, am I a little late? Why is everyone so early?"
"We just got here too. You're not late at all, Professor. Haha."
They laid on the flattery thicker than they ever did in class.
"Shall we warm up a bit and then head out?"
"Yes."
Her clothes alone were a world away from the neat suits she wore on campus. She had on the kind of outfit young women wore to the gym — body-hugging leggings, a tight sleeveless sports bra top, and a sheer windbreaker draped over it.
Has she always had a body like that? The thought refused to leave my head.
When she bent deep at the waist to stretch, the firm curve of her ass and the long line of her legs in those leggings were dizzyingly sexy. She'd pulled her short hair into a tight ponytail, baring the pale column of her neck beneath her ears, and my eyes locked onto it. I just stood there staring while she warmed up.
"Minwoo, you're not stretching?"
Jaehun's voice snapped me back.
"Ah — right. I already did at home. This is fine. Hup."
I went through the motions. And kept sneaking glances at her figure.
She was shorter than average, but those long slim legs, that tight round ass, the narrow waist set against a surprisingly full chest — she could have passed for a model. True to her perfectionist nature, she clearly managed her body with the same ruthless discipline she brought to everything else.
"All right. Shall we take it easy and start running?"
Warm-up done, Professor bounced in place as she spoke. Every time she landed, her breasts bounced with her. The sports bra was fighting a losing battle against that much volume.
"Let's go!"
Jaehun took off first, fired up. The others fell in behind him, and naturally Professor and I ended up running side by side.
"Minwoo, did you eat?"
"Yes. You, Professor?"
"Just a banana."
We kept up a light stream of small talk and matched each other's pace. Jogging and chatting like this, stripped of the authority she carried on campus, I felt a faint, unexpected closeness to her.
"You're a strong runner, Professor."
"This is nothing — I run every day. Hah… hah…"
Beads of sweat gathered on her forehead, slid down her cheek, traced her neck, and disappeared into her sports bra. I couldn't see it, but I knew the path it took — down the valley between her breasts, over her stomach, soaking into her panties inside the leggings, rubbing into the cleft between her legs. That heated sweat would carry a bitch-in-heat musk all its own, rising off her body and trailing behind her on the air.
I drifted a half-step behind her and drew a deep breath.
Hnnn…
"Hah…"
Her skin, her perfume, and her sweat blended into something like pheromone, tugging at my reason. With every stride, blood pooled lower; my cock stiffened by degrees inside my shorts.
"Feels good, right, Professor? Running like this?"
"Mm. So good. Hah… hah… You too, Minwoo?"
"Yeah. I like it a lot."
From behind, her ass flexed left and right in time with her stride — high, springy, not a hint of sag. I wanted nothing more than to bury my face between those cheeks. I stayed on her heels, drinking in her scent, drinking in the view. In my head she was already naked and fucking me.
To hide the filthy turn of my thoughts I occasionally pulled ahead of her — then dropped back again and fucked her all over in my imagination.
We ran a long stretch before we finally hit the turnaround and came back to where we'd started. The others had already finished; they were sprawled on the grass, chugging water. Professor and I arrived breathing hard.
"You're a solid runner too, Minwoo. Do you work out regularly?"
"Yes, Professor. I hike sometimes, jog sometimes."
"Oh my. I love hiking. Mind if I tag along sometime?"
She looked at me with bright, curious eyes.
"Of course. I'll take you up whenever you'd like."
"Going with you already makes me feel safer. Heehee."
"I'll get you to the summit in one piece."
I stepped one foot back, swept an arm out, and gave her a mock Western bow. She played along, pretending to lift an invisible skirt and dipping into a little curtsy.
"Why, thank you."
The guys watched our little pantomime and started whining that they wanted to go home. We wet our dry throats, exchanged quick goodbyes, set a date for next week, and split up.
I drove home. After so long without a real run, my legs felt pleasantly spent. Inside, I showered, then stretched out on the bed and let my mind drift back to Professor — that body, that rear view. I undid my pants, wrapped a hand around my already-hard cock, and started stroking.
That was when someone knocked at the front door.
Knock-knock-knock.
"Minwoo?"
The landlady.
