Breaking a Sweat
Marc arrived at the Englischer Garten on Thursday evening with his running gear already on under a light hoodie. The late September air carried the first real bite of spring, crisp and clean, but his blood felt warm the moment he spotted Frank waiting near the Chinese Tower. The older man stood with his arms crossed, dressed in another set of tight black running clothes that left little to the imagination. The compression fabric stretched across his broad chest, outlining the firm swell of his pectorals and the faint shadow of trimmed chest hair beneath. His muscular thighs filled the shorts completely, and once again that heavy, prominent bulge sat front and center, thick and unapologetic. Frank looked every inch the disciplined alpha, neat beard perfectly trimmed, short brown hair styled even for a run, hazel eyes scanning the path with impatient authority.
“You’re on time,” Frank said by way of greeting. No hello, no small talk. Just that deep, clipped voice that somehow managed to sound both approving and challenging at once.
Marc pulled off his hoodie and stuffed it into his small backpack. “Told you I would be.”
Frank’s gaze flicked over him once, quick and assessing. Marc felt it like a physical touch, sliding across his lean athletic frame, the fitted gray tank, the black compression shorts that hugged his own trimmed blond body hair and the average but neat bulge between his legs. Frank didn’t comment. He simply turned and started jogging, setting the same solid pace as before.
They fell into rhythm side by side. The gravel crunched under their shoes. Leaves rustled overhead. For the first kilometer they ran in silence again, the only sounds their steady breathing and the occasional distant laugh from other park visitors. Marc kept his stride easy, matching Frank exactly. He could have pushed harder. His legs felt fresh, his lungs strong from years of consistent training. But he held back, letting Frank lead, letting the older man think he was setting the standard.
After fifteen minutes Frank spoke, voice slightly rough from the effort.
“Most people quit after the first session. They say I push too hard.”
Marc glanced sideways. Sweat was already starting to darken the neckline of Frank’s top. A single drop traced down the side of his neck and disappeared into the collar. Marc forced his eyes forward.
“I’m not most people,” he answered simply.
Frank gave a short, humorless huff that might have been a laugh. “We’ll see.”
They continued along the familiar loop. The path narrowed in places, forcing their shoulders to brush occasionally. Each contact sent a small jolt through Marc. Frank’s body radiated heat, solid and powerful. Marc could smell the clean scent of his cologne mixed with fresh sweat, masculine and intoxicating. He felt the slow burn building low in his stomach, a warm tension that had nothing to do with the run and everything to do with the man beside him.
Halfway through the run Frank picked up the pace a fraction. Marc matched it without comment. His heart rate climbed, but he stayed controlled, breathing steady. Frank’s breathing grew a little heavier, the powerful muscles in his back and shoulders working visibly under the tight fabric. Marc watched the play of those muscles from the corner of his eye, the way Frank’s ass flexed with each stride, round and firm. The heavy swing of Frank’s large cock in those tight shorts was impossible to ignore completely. Marc felt his own cock twitch in response, thickening slightly against the compression material. He was grateful the shorts were dark enough to hide any obvious reaction.
They finished the five kilometers in good time. Both men were breathing harder now, chests rising and falling, skin glistening with sweat. They slowed to a walk near the fountain. Frank bent forward, hands on his knees for a moment, giving Marc a perfect view of the broad, muscular back and the way the shorts clung to his powerful glutes. When Frank straightened, his face was flushed, beard damp, eyes bright with the endorphin rush.
“Not bad, Fischer,” he said. The words sounded almost grudging. “You kept up.”
Marc wiped sweat from his brow with the back of his arm. “Felt good. Same pace again next time?”
Frank’s mouth twitched, the closest thing to a smile Marc had seen. “We’ll see if you still say that after the third run.”
They stood there for a minute, catching their breath. The tension between them felt thicker than the humid evening air. Marc’s gaze drifted involuntarily to Frank’s chest, where the compression top clung transparently to his nipples, then lower to the prominent bulge that looked even heavier now, slightly more defined after the exertion. Frank caught him looking. For a split second their eyes locked. Marc felt heat flood his face, but he didn’t look away. Frank’s expression remained unreadable, though something flickered in those hazel eyes, something dark and assessing.
“Shower at the office locker room?” Frank asked, voice lower than usual.
Marc nodded. “Yeah. I’ll head back with you.”
They walked the short distance to the company building in relative silence. The locker room on the basement level was empty at this hour. Marc followed Frank inside, heart beating a little faster. The space smelled of clean tile and faint disinfectant. Rows of lockers, wooden benches, open showers along the far wall. Frank stripped without hesitation, peeling the damp compression top over his head to reveal a muscular, hairy torso trimmed to perfect neatness. Dark hair covered his broad chest in a neat pattern, narrowing to a trimmed treasure trail that disappeared into the waistband of his shorts. His arms and shoulders were thick with muscle, veins standing out from the run. When he pushed the shorts down, Marc had to fight not to stare openly.
Frank’s cock was everything the tight running gear had promised and more. Large, thick even soft, uncut with a generous foreskin covering the head. It hung heavy between powerful, hairy thighs, the dark pubic hair trimmed short and neat. His balls were full and low. Frank stood there completely unselfconscious, alpha confidence radiating from every inch of his fit forty-six-year-old body. He grabbed a towel and headed toward the showers, giving Marc a brief view of his muscular ass, also dusted with trimmed hair.
Marc turned away, pulse racing, and quickly stripped his own clothes. His lean athletic body felt almost boyish next to Frank’s mature power. Blond body hair trimmed to the perfect length, smooth chest with just a light dusting, flat stomach, average-sized uncut cock that was already half-hard from the visual overload. He wrapped a towel around his waist and followed Frank into the shower area.
The showers were open, no stalls, just a row of heads along the tiled wall. Frank had claimed the far one and was already under the hot spray, head tilted back, water cascading over his shoulders and down the planes of his back. Marc took the shower two heads away, giving them both space, but the distance felt meaningless. He turned on the water and let it sluice over his heated skin, trying to calm his breathing.
They showered in silence for a few minutes. Marc kept his back mostly to Frank, but he couldn’t stop the occasional glance. Frank soaped his chest with slow, deliberate strokes, fingers moving through the wet chest hair, down over his abs. When he washed lower, Marc caught the movement from the corner of his eye: Frank’s large hand sliding over that thick cock, soaping the length, pulling the foreskin back briefly under the water. Marc’s own cock swelled fully now, pressing against the towel he had hung on the hook. He faced the wall, willing himself to calm down, but the image burned behind his eyelids.
“First week treating you okay?” Frank asked suddenly, voice echoing off the tiles.
Marc cleared his throat. “Yeah. Emily’s been great. Josh too. The BMW files are intense, but I’m getting through them.”
Frank grunted. “Good. I expect you to pull your weight on the new pitch next month. No hand-holding.”
“Understood.”
Another silence. Marc risked a quick sideways glance. Frank had turned slightly, rinsing the soap from his front. Water ran in rivulets down his hairy chest, over the defined ridges of his stomach, and straight down to the heavy cock that now looked slightly thicker, the foreskin pulled back just enough to show the flushed head. Marc’s mouth went dry. His own erection throbbed painfully. He turned the water cooler, hoping it would help.
When they finally shut off the showers and walked back to the benches to dress, the air between them crackled. Marc kept his towel wrapped tight as he dried off, but he was achingly aware of Frank only a few feet away, naked and completely at ease. Frank pulled on fresh clothes, a casual polo and jeans that still managed to look expensive. Marc dressed quickly, trying not to let his gaze linger on the way Frank’s jeans hugged his thick thighs and the prominent bulge that was once again on display.
Before they left the locker room, Frank paused at the door.
“Saturday morning run,” he said. “Seven sharp. Same place. You up for it?”
Marc met his eyes. The tension was unmistakable now, at least on his side. He wondered if Frank felt even a fraction of it.
“I’ll be there,” Marc answered.
Frank nodded once, then walked out.
Marc stood alone for a moment, exhaling slowly. His cock was still half-hard, his skin tingling. The slow burn had just turned up another notch, and they had barely spoken ten sentences to each other.
Back at his apartment in Schwabing, Marc unpacked another box while his mind replayed the evening on loop. The brush of shoulders on the path. The sight of Frank’s powerful body under the shower spray. The heavy, uncut cock swinging as he moved. Marc’s hand drifted down unconsciously, palming himself through his sweatpants. He thought about Frank’s deep voice, the arrogant tilt of his head, the way he pushed without apology. Marc liked it. More than he probably should.
He stripped and lay on his bed, hand wrapping around his cock. He stroked slowly, eyes closed, imagining Frank’s larger one, imagining those strong hands on his hips, that neat beard brushing against his neck. The fantasy built quickly. Marc came with a quiet groan, spilling over his trimmed blond pubic hair, chest heaving.
Afterward he lay there, staring at the ceiling, a small smile on his face.
This was only the beginning. Frank’s shell was thick, grumpy and snobbish on the surface, but Marc could already sense something deeper underneath. Something worth the slow, patient burn. He would keep matching Frank’s pace, keep showing up, keep letting the tension simmer.
And eventually, he would crack that shell wide open.
The next day at the office passed in a blur of meetings and client research. Emily helped Marc navigate the complex BMW stakeholder map. Chris kept mostly to himself but offered a surprisingly insightful comment during a team huddle that earned a rare nod of approval from Frank. Josh pulled Marc aside at lunch, eyes sparkling with mischief.
“So, how was the death run yesterday?” he asked, biting into a sandwich. “Did Frank make you cry yet?”
Marc laughed. “Not even close. It was good. I like running with him.”
Josh raised an eyebrow. “You like running with the grumpy alpha who eats interns for breakfast? Bold choice, blondie.”
Marc shrugged, keeping his expression neutral. “He’s a strong runner. Pushes me. That’s all.”
Josh studied him for a second, then grinned. “Uh-huh. Sure. Just be careful. Frank doesn’t do friends. And he definitely doesn’t do… whatever you’re thinking with that look on your face.”
Marc felt heat creep up his neck but played it off with a laugh. “No idea what you mean.”
Josh just shook his head, still smiling. “My advice? Keep your heart and your dick in separate boxes for now. Frank’s complicated.”
Marc took the warning seriously, but it didn’t stop the anticipation building in his chest for Saturday morning.
When Saturday arrived, he was at the park by six fifty, stretching under the trees. Frank appeared right on time, looking somehow even more imposing in the early light. Same tight running kit, same powerful body on full display. They exchanged the briefest of nods and started running.
This time the pace felt a touch faster from the start. Marc matched it effortlessly, keeping his breathing even. They ran longer today, nearly seven kilometers. Sweat poured down both their bodies. Shoulders brushed more often on the narrower sections of path. Each time the contact lingered a fraction longer. Marc’s skin felt electrified. When they finally stopped, both men were breathing hard, faces flushed.
Frank wiped his face with the hem of his tank, exposing a strip of hairy, muscular stomach. Marc’s gaze dropped before he could stop it. Frank noticed. Again.
“Shower?” Frank asked, voice rough.
Marc nodded.
Back in the empty locker room the routine repeated. Clothes came off. Bodies stood under hot water. This time Marc allowed himself a longer look when Frank wasn’t watching. The way water clung to the dark hair on Frank’s chest. The thick, heavy cock hanging between those powerful legs, swaying as Frank shifted his weight. Marc’s own cock filled rapidly. He faced the wall, but the ache was becoming harder to ignore.
They dressed in charged silence. Before leaving, Frank paused again.
“Tuesday. Same time.”
It wasn’t a question.
Marc met his eyes. “I’ll be there.”
Frank’s gaze held his for a beat longer than necessary. Then he turned and walked away, leaving Marc with another night of heated fantasies and the growing certainty that the tension was no longer one-sided.
The work week continued. Marc impressed everyone, including Frank, with a sharp analysis on the new project. Frank acknowledged it with a short “Solid work, Fischer” in the team meeting, the closest thing to praise Marc had heard from him. The words sent a warm flush through Marc’s chest that had nothing to do with professional pride.
Tuesday evening arrived. Another run. Another shower. The brushes of shoulders on the path grew more frequent. In the locker room the air felt thicker, hotter. Marc’s erection was impossible to hide completely this time. When he turned slightly while rinsing, he caught Frank’s eyes flicking downward for the briefest moment. Frank’s own cock looked heavier, the foreskin slightly retracted, though he said nothing.
They parted with the usual curt nod, but the heat between them had climbed another degree.
By the end of the second week, Marc could feel the slow burn turning into something sharper, more insistent. Frank remained grumpy and snobbish at the office, barking orders and keeping everyone at arm’s length. But during the runs and in the quiet moments of the locker room, something was shifting. Small comments. Longer glances. A grudging respect that felt like the first crack in that thick, armored shell.
Marc was patient. He would keep showing up. Keep matching Frank’s pace without revealing his full strength. Keep letting the tension simmer and build.
Because he knew, deep down, that when that shell finally cracked, the heat would be worth every slow, aching minute.
