At the end of his free workout, Chandler felt sore. He could not recall any other time exercise had left him feeling this drained. Sure, he had complained the whole time Dave showed him how to optimize his gains, but Chandler could not have asked for a better time. With each new tutorial, there was a new chance to feel the trainer's hands on him, guiding him into the correct position. Now that they were through, Chandler could not decide if he were more relieved to be giving his muscles a break or disheartened that his buff athletics enthusiast would not touch him anymore.

"Now comes the part where we stretch." Dave clapped his hand on his client's shoulder and guided him back into his office.

"Stretch? Didn't we just—"

"No, Mr. Bing. Stretching is what will help ease your stiff muscles. You need to do this after every workout to help with recovery and flexibility." Dave's hand squeezed Chandler's shoulder at the word "flexibility."

Chandler lay down on his back and allowed the trainer to maneuver his legs so that he had to wonder whether his lower limbs would be in knots by the end of the stretches. Dave pushed Chandler's right leg back towards his head and held it in place for ten seconds. At first, the stretch felt as though it might rip him in half, but then he realized how relaxing it felt to have the trainer positioned so close to his ass.

"Let me know if this is getting to be too much." Dave always seemed to worry about Chandler's comfort despite forcing him into compromising poses on the gym floor.

"Oh, you're good." That came out in a moan. A few seconds later, he realized, he could feel a thick object pressing against his glutes. Rather than spark alarm, the touch prompted his own cock to stiffen to attention like an obedient soldier. Chandler watched as his hand reached out and caressed Dave's hairy arms.

Dave smiled down, hunger in his eyes.

Ross approached the front desk one more time, drawing a perturbed frown from the man working there. "Hi, it's me again. Do you happen to know how long it will be before Dave is ready to help me quit?"

The man gnashed his teeth. "His office is on the left."

"Thanks."

"Just get out of my hair!"

"Right."

Ross followed the grumpy man's directions to a closed office door. Tucked away from the main exercise floor, people would have to be looking for the room in order to find it. Through a crack in the blinds covering the door window, Ross could see light and a hint of movement. He turned the knob and pushed the door open a crack. What he saw made him glad the hinges were not squeaky.

Chandler lay on the floor, gazing up at a bulky man who slid a hand under Chandler's shirt. The larger man bent lower and kissed Ross's friend as if trying to eat his face. The two slid their tongues into each other's mouths, moaning as the exchange created popping sounds.

The man on top broke of the kiss and peeled off his black polo. Chandler could not tear his eyes away and felt up the man's hairy chest. "Could you have a nicer body?" Ross's friend lifted his back off the floor and licked the man's furry nipples, drawing out growls of pleasure from the big man.

The trainer held Chandler's head up to his chest. "It takes work, but you'll get there."

Smiling, Chandler sucked at the man's right teat as if it would produce milk. His hands roamed Dave's muscular back, searching for the best way to hold on.

As he watched, Ross struggled for a proper response. He could not yell out in shock, for his breaths came out in ragged whistles through his wide-open mouth. Rather than do the rational thing and close the office door, his elbow bumped the opening a little further to give him a better view. His head whipped around as if looking for an escape route, but his mind only noticed that no one else on the gym floor could see inside. Indeed, no one would be able to see him either, unless someone else managed to get by Maria's tantalizing smiles.

Dave pulled Chandler's gray t-shirt over his head, revealing the man's pasty white torso. Though he did not have a flabby gut from lack of activity, Chandler's physique might as well have been a lump of clay next to Dave's sculpted body. Despite his friend's unimpressive… everything, Ross could not stop staring as Dave smashed his mouth against Chandler's. Someone grabbed his crotch, and Ross looked down, stunned to see his own hand there, rubbing.

"You ever suck a dick before, Mr. Bing?" Dave asked.

"Only once. And he said it was just a one-time thing, so I don't think he'll see it as cheating if—"

"Y'know, most guys just say 'yes' or 'no.' They don't give their life story." Dave chuckled at the rambling.

"Oh, so you're gay, then?" Chandler surmised.

"No. We've been kissing and grinding on each other because no woman would ever find me attractive."

Chandler laughed. "Usually, I'm the sarcastic one, but that was pretty good."

"You seem nervous."

"It's just that I'm not really gay. Curious is all. Do you know what I mean?"

Dave sat back on his haunches, regarding Chandler with an upturned eyebrow. "I've met curious before, Mr. Bing. It's usually not this eager. If you're nervous, don't worry. I'll take care of you. Just tell me if you want this or not."

Ross held his breath as he waited for the answer. He could feel the sausage in his pants plumping like a Ballpark Frank.

"I do!" Chandler said. He reached out for the waistband of Dave's gym shorts and pushed down. His eyes bulged at the sight of an old-school white jockstrap failing to contain an erect penis.

Ross exhaled, somehow more excited than before. Last week, when he had spied Chandler and Joey together on the recliner, he had told himself the novelty of seeing his best friends in that light had addled his brain. Watching two men being intimate did not arouse him. At least, that was what he kept telling himself as he awoke from dreams of the two doing more than just kiss naked on a La-Z-Boy. Now, however, he could not dismiss his blood pumping through his penis so easily. Especially when his cock twitched within his briefs, demanding immediate attention.

That enticing package begged for attention. He could see a dribble of precum seep out over the top of the jockstrap. Licking his lips, Chandler bent forward to lick up the liquid. It tasted like jellybeans left out in the sun, salty yet sweet. Though not a drink he would order at a restaurant, he would not turn down another opportunity to try Dave Juice. His nose picked up the scent of sweaty balls from the jock, and the odor triggered an unexpected release of dopamine in his brain.

Dave slipped the jock down, releasing his cock to smack Chandler in the cheek. Chuckling in the back of his throat, Chandler gripped the phallus in his hand and licked around the tip. He moaned, running his tongue up and down along the underside before swallowing as much as he could. Managing only two-thirds of the dick before his gag reflex forbade further movement, he backed away and coughed. A string of spittle connected his lips with the cock head a few moments before breaking away and dangling on his chin.

"You okay?" Dave asked.

Chandler nodded, still coughing like a cat hocking a furball. "You're a bit wider than Joey."

"Who's Joey?"

"Not important." He managed to take an uninterrupted breath.

"Do you need to stop?"

Chandler cleared his throat and focused on the prize in hand. It had tasted so good in his mouth. "Does the Pope believe in karma?"

Blinking, Dave shrugged. "How would I know?"

"Karma's a concept from – you know what? Short answer's 'no.' Let's go with that."

The pair laughed for a moment before Chandler resumed sucking on Dave's schlong. Bobbing his head up and down, he made sure to stop himself short of producing another interruption. Knowing his limits allowed him time to apprehend how a thicker dick might make the experience even better than his first time having one up his ass. With every plunge down the shaft, Chandler found himself anticipating inserting up his other end. Perhaps Dave had been right, and curiosity did no longer described him.

Every few minutes, Ross checked his surroundings to make sure no one had caught him peeping with his hand down his pants. That would have been an awkward conversation. Yet watching Chandler giving a blow job did not cause him to wonder whether his friend had been lying to him for years. Rather, it made him imagine himself on the receiving end. Given the trainer's subdued cries of encouragement, Ross knew the experience would be unforgettable.

"Let me see what you're working with," Dave insisted.

Unthinking of potential consequences, Ross took the order as if directed at him. He slipped out his erection, letting it rest atop his partially unzipped khaki pants. Inside the office, Chandler stood and pulled his baggy gym shorts and tidy whities down to his ankles. The man's cock saluted the trainer once free of its restraints. Ross noticed that while Chandler's tool did not have the same heft as Dave's, it won in the length department. Even so, Dave managed to swallow the whole thing in one gulp.

"How'd you do that?" Chandler asked, amazed and aroused.

Dave backed off the dick and glanced up, smiling. "I'm a physical trainer, Mr. Bing. One thing I've taught myself is how to relax my body. If you can get your throat to ease up, you can—"

"You know what, I don't actually need to know this minute." Chandler pulled Dave back onto his dick, gripping the man behind then neck. "Just suck on it."

If Chandler's abilities with a cock in his mouth had turned Ross on, the watching Dave at work almost had him spurting then and there. He almost forgot to check for gym members who might catch him in the act.

Ross stroked his dick harder, feeling the veins pop up as his fist ran up and down his own length. He envied Chandler's good fortune in getting a chance to come back here first. If he had not let Maria distract him in the atrium, this could have been him getting the blowjob from a Greek god incarnate.

After a few minutes on his knees, Dave distanced his mouth from Chandler's cock. Sweat beaded down his forehead, and he gasped for breath. "I want you to fuck me, Mr. Bing."

With those words, Ross's cock let loose a load of cum. He had to force himself not to cry out as his body temporarily felt like a marionette cut from its strings. His jizz splashed against the office door and dribbled onto his hands. Whipping his head around, he stuffed himself back into his underwear, closed the door as quietly as he could, and dashed off for the bathroom. Thoughts of guilt flooded into him. The sticky glob on his hand might as well have been Lady MacBeth's spot. No matter how he scrubbed, Ross would always know he had spied on his best friend and fantasized.

Chandler could not believe his ears. How could a man like Dave, such a massive guy, want little ol' Chandler fucking him? "Shouldn't it be the other way around?"

Dave stood, wrapping his bulky arms around Chandler's back in a bear hug. With all the hair on his considerable chest scratching him, the man could have been a bear. The trainer kissed his trainee. "No. I'm what you'd call a bottom. I can give, but I prefer taking."

"So, in a game of Cops 'n Robbers, you'd be the thief?"

Letting loose a short blast of laughter, Dave kissed Chandler again. "This is why I like you, Mr. Bing. You can always make me laugh."

"How do you want to do this?" Chandler asked.

"What do you mean?"

"I'm pretty sure that if you try sitting on it, you'll end up crushing me like a Capri Sun. As fun as that is to do, I'd rather come out of this able to walk."

Snickering, Dave bent onto hands and knees. "Doggie it is, then."

Chandler had his first real look at the man's rear. If Dave's body had filled him with lust before, it had been a teensy measure compared to the desire welling up within now.

"Do you have any condoms?" Chandler asked.

"Sure. Middle drawer."

Chandler ran to retrieve one. He ripped open the golden square package. In his haste, he tried putting the rubber on backwards. Dave spotted the difficulty and rolled the protection onto Chandler's cock.

Everything now in place, Chandler spat on his rod and positioned it behind Dave's rear entry. Remembering how painful Joey's initial insertion had been, Chandler moved in slow and steady. Even so, Dave still gasped. He stopped all progress. "Sorry."

"Don't be sorry. Just keep going. It feels great."

Chandler moved all the way in. The inside of that ass squeezed his dick so much better than a hand. It felt so warm and wet in there. He pulled back a little before thrusting back in. A moan escaped his mouth at the same moment Dave cried out in triumph. Chandler grinded into the ass at a steady beat, feeling the pressure against his cock intensify with every second. Compared to fucking any of the previous girls in his life, this felt like the ultimate high. Any substitutes for a butthole would be disappointing from now on.

Unexpectedly, the friction on his phallus drew out an orgasm from Chandler. His condom filled with sperm as his cock softened. He tried to reignite his inner flame, but no sparks took. Poor Dave had not reached satisfaction.

"I'm sorry. I hope this wasn't too much of a disappointment."

Dave turned around, smirking. "Disappointment? You do realize that there are two of us with cocks, right? I said I prefer taking. Well, I did just now. But I also said I can give."

Chandler grinned.

"Though, I'm not worried about having all my juice squeezed out of me," Dave joked. "So, I want you to sit on my dick."

Chandler pulled out of Dave, ripped off his condom, and threw it in the garbage bin beside the office desk. He retrieved another shiny package from the middle drawer and fitted elastic protection onto Dave before positioning himself above the thick, erect dick. The pain he felt subsided quick enough as he lowered himself all the way. As he slid down the cock, he moaned loudly.

"Well, look at that!" Dave said.

"What?" Chandler asked, panting.

"You just did a perfect squat. Looks like you did learn something out there today." The two laughed as they kissed. Dave thrust up into Chandler and said, "Are you still thinking of quitting?"

"No way," Chandler objected. "Not if I can get more sessions with you."
