Lav leaned against the door to the living room, smirking. His bright purple bathrobe clung to his shoulders, and was tied tight around the front. The hallway behind him was dark; the room before him was dimly lit by a dozen candles and a tall, shaded lamp. The flickering light danced played across his glasses and mane. His eyes were pointed straight forward, directed toward the sole occupant of the loveseat facing toward the fireplace.

It was an old loveseat, a comfy, orange thing that had big, soft cushions and a tendency to make its occupants fall asleep. The pegasus sitting upon it wasn’t snoring, though; he had a book in his hands, and was quietly reading. He also had the particularly unique quality of filling up the loveseat completely. His broad shoulders stretched across most of the space between the arms, and his back stuck up a good six inches over the top. Lav couldn’t see it from here, but he knew that the cushions would have sunk low beneath Cheer’s rear, the loveseat groaning under his near quarter-tonne weight.

It was hard, really, for Wind Cheer’s surroundings not to look small compared to him. Seven-plus feet of stallion made for an awful lot of pony, and his musculature exaggerated his already oversized frame. The book in particular looked like a foal’s toy, held carefully as it was in his big, single hand.

The lamp cast his dark green mane into light, long, scraggly hair falling untidily over his thick shoulders and onto his chest. Each inhale sent Cheer’s chest pushing upward, swelling and stretching his button-down shirt. Lav eyed them hungrily, his smirk widening as he ogled the broad curve of Cheer’s pecs. Years of working out and a body primed for growth had given them the perfect, almost bouncy look. But Lav knew from experience that even those rock-hard pecs could be soft and warm to the touch, if only a stallion knew where to touch. His hands pushed down in the pockets of his robe, brushing against the bulge at his own crotch through the soft, fuzzy fabric.

When he pulled his hands back out and crossed his arms, he’d left a damp spot showing through the dark purple of his bathrobe. But Lav had eyes only for Cheer—specifically the way his shirt seemed to barely contain his big, strong body. His biceps, bulging three times the width of Lav’s own; his thighs, looking big enough to split the seams of his pants if he so much as flexed the wrong way. And the mountain of a bulge at his crotch...it was simply obscene. Perhaps in public, a looser pair of pants would not have strained the bounds of modesty quite so much, but the way Cheer’s legs were spread forced his package up against the fabric, leaving precious little to the imagination.

Lav licked his lips, feeling his own crotch stiffening. His hardening cockhead brushed again against the inside of his robe, leaving a smear of pre across it. He couldn’t help it. Just looking at Cheer never failed to get him excited, even during the first time he’d seen the big pegasus’ endowment in an ostensibly medical capacity. The way Cheer filled out his clothes, dominated the loveseat...and with such apparent ease, too. If Lavender hadn’t been so eager to make good use of his coltfriend’s body, he would have been downright jealous.

He approached with a saunter in his step, his slippers shuffling quietly on the carpeted floor. If Cheer heard him approaching, he gave no sign; he merely frowned contemplatively to himself, nodded, and turned to the next page of his book. Lav rolled his eyes mentally and rounded on the loveseat from the back.

“Hey there, hunk,” Lav purred. He took hold of Cheer’s biceps and gave them a squeeze. His hands moved up and covered Cheer’s eyes. “Guess who?”

Cheer sighed, though Lav could hear the smile in it. “I didn’t hear you get out of the shower,” he said, without turning around.

“Too busy reading?” Lav said. He smoothed his hands out across Cheer’s broad chest. The fabric was stretched tight across his his coltfriend’s pecs; he would’ve sworn he could have felt Cheer’s heart beating as he rubbed into the soft, smooth surface. He pressed the side of his head against Cheer’s, nuzzling against his ear. “Was wishing you could’ve joined me.”

His palm brushed across one of Cheer’s nipples: which was hard against the fabric of the shirt. Cheer grunted—then moaned softly as Lav reflexively gave it a squeeze.

What happened next made even Lavender’s eyebrows go up. Cheer’s entire body seemed to stiffen. His pecs swelled against his shirt, the fabric growing tighter beneath Lav’s palm. His arms flexed hugely, biceps and triceps alike swelling a good quarter in size. There came a low, steady ri-i-i-i-p.

Cheer’s moan instantly stopped. He and Lav blinked together down at the long, four-inch rip that had appeared down his right sleeve, just below Lav’s elbow. The checkered fabric had torn along the curve of his bicep, a few split threads fraying around a patch of bright green fur.

Lav whistled. “Did not know you could do that.”

“Because I try not to,” Cheer groused. He lifted a big hand to thumb at the hole. “Now I’ll need to sew that back—”

Lav squeezed his other nipple.

This time, it was absolutely clear that Cheer could not hold back his ensuing groan. It wasn’t a groan of pleasure so much as one of tightness, of desire, of momentary physical bliss. His arms flexed again, biceps and triceps alike bulging bigger than Lav’s entire head. As a seven-foot-plus pegasus, Wind Cheer had a wingspan larger than any Lav had ever seen, save perhaps one of the Wonderbolts. His wings stretched out behind him, stiffening and rising up along the edge of the couch. A split-second later, a pair of rips echoed through the air. The top button of his shirt creaked ominously, his chest swelling bigger as Lav gave his nipple another playful flick.

Cheer caught Lav’s wrist in his hand before the smaller stallion could go any further. His eyes, though, were only for the new tear along his left sleeve, just a bit smaller than the newly widened one on his right. A thick slab of rounded muscle poked through, looking absolutely delicious.

“I liked this shirt,” Cheer said mournfully. Lav just smirked and gave him a kiss on the cheek.

“I do, too,” he said, grinding his crotch not-so-subtly against the back of the couch. “But I like what’s inside of it even more.”

Before Cheer could stop him, Lav’s free hand was on his nipple. This time, he wasn’t happy to just squeeze it—instead, he gave it a twist between his thumb and forefinger, massaging it gently against his palm. Cheer’s ensuing groan of pleasure was unmistakeable. His entire upper body bulged as every muscle flexed hugely. His massive biceps burst right through his sleeves in an instant. Three buttons rocketed off of his shirt, flying through the air and away from the pair of basketball-sized pecs that had just forced their way up into the air.

They bounced lightly; Lav moved his other hand over and gave one of them a squeeze. At his touch, Cheer’s flex seemed to melt away, allowing Lav’s fingers to sink deep into the soft, cascading muscle. Cheer groaned, his eyelids fluttering.

“Lav,” he sighed, “at least tell me when you’re horny so I have a chance to change?”

“Horny? Who, me?” Lav made an attempt to sound innocent, but put no real effort into it.

Cheer just turned and raised an eyebrow at him. Then he glanced down at the tatters of his shirt. The sleeves and upper buttons had all but exploded off of him, leaving his wide, expansive chest free to inflate impressively. The beginnings of a set of washboard abs began just below the lower part of his shirt, the part that was somehow still managing to cling around his waist.

Lav sucked in a breath. “Okay, fine,” he said. He smoothed a hand across one of Cheer’s pecs, marvelling at just how smooth it was. “But I can’t help it if you turn me on no matter what you do. You’re just too much stallion for my libido to ignore.”

“Long day at work?” Cheer offered.

Lav snorted. “You have no idea.” He moved his hand up to Cheer’s right arm and began massaging his bicep. His fingers slid easily beneath the tears in the other stallion’s shirt and wrapped around the bump they found there. He had absolutely no chance of wrapping them around completely, of course, but that didn’t seem to keep him from stopping. “Just one appointment after another. And those Canterlot unicorns - the worst patients I’ve ever had to deal with.” He snorted. “And the weather didn’t help one bit.”

Cheer’s arm flexed a bit beneath his fingers, and Lav found himself biting his lip, his crotch stirring madly. He was fully hard now, his cock pinned between his hips and the back of the couch. Had he been leaning further forward with his robe open, Cheer would have certainly been able to feel Lav’s stiff flare brushing across his back. And given the way Cheer had just hulked out of his shirt...Lav certainly wouldn’t have minded grinding his stallionhood between his oversized coltfriend’s trapezoids.

“How about your day?”

“Not too bad,” Wind Cheer said noncommittally. “Just a bit distracting sometimes.”

“Distracting how?” Lav said. Cheer suddenly made a very obvious effort to avoid meeting his eyes. Lav’s gaze drifted over his coltfriend’s torso, then down toward his crotch, where a simply massive bulge was straining against the fabric of Cheer’s loose pants. A feather from Cheer’s wing brushed against his neck, the big stallion’s wings stiffening further.

Lav chuckled softly. He gave Cheer’s big, meaty bicep another squeeze. “Somepony’s pent up, huh?” he asked. He reached forward to grope again at Cheer’s big, squishy pecs.

Cheer groaned. “N-no,” he mumbled. Then there came another ripping sound, this one long and drawn-out. When both stallions looked at Cheer’s crotch, his right pant leg had ripped partially right down the seam. A generous amount of cockflesh poked through the tears in the fabric, twitching and throbbing obviously. Beneath it, the round curve of Cheer’s groin betrayed a pair of equally large testicles that had to be absolutely stuffed with seed. Lav licked his lips, feeling a bead of pre gathering on his own tip.

Cheer stared at his lap. His massive cock flexed, straining harder against its cloth prison. Already, his pant leg looked like it had been stuffed with a second leg, and there was a damp spot slowly running down toward his knee. With each inch of stiffness his shaft gained, the smear of precum against his leg darkened and pushed forward, staining his torn pants further.

Cheer sighed. “Okay, maybe a little. But I was perfectly fine before you came over.”

“As if you’re not more than stallion enough to need to empty those nuts once every few hours, anyway.” Lav’s hand ran down Cheer’s arm as the smaller stallion made his way around the loveseat, his hips swaying. His fingers tightened below Cheer’s forearm, marvelling at the raw power he could feel in the big pegasus’ frame. He paused in front of the loveseat, then glanced down at Cheer with a smirk. “Well. Maybe not yet, anyway,” he added, eyeing Cheer’s huge biceps and plump pecs meaningfully.

Cheer glanced down at his chest. His pecs had grown along with his biceps from Lavender’s teasing, and now resembled a pair of small beach balls more than anything. A touch of Lav’s fingers to the bulge at his crotch made him flex involuntarily; when he relaxed, his muscles were left a bit larger than they’d just been before. Not too much larger, but enough to notice.

“I told you,” Cheer said. “I don’t want to get too much bigger.”

He grunted as Lav sat himself down on his lap facing toward him. Lav sucked in a breath, his bathrobe bulging around his own erection as he ran his fingers over Cheer’s rock-hard abs. He had to straddle Cheer, both legs resting on the larger stallion’s tree-trunk thighs. Lav grinned up at his coltfriend as he fidgeted, shifting over until Cheer’s enormous, half-flaccid cock was clamped right between his buttcheeks.

He gave them a flex, and was instantly rewarded for his efforts when Cheer let out a throaty moan. It turned into a growling, half-restrained groan of pleasure as he took Cheer’s nipples and gave them another squeeze. When Cheer flexed in response, his muscles swelled even bigger once again, leaving them with an obvious “pump” that would only grow as he became more aroused.

Lav’s fingers sunk deep into Cheer’s plump, meaty pectoral, molesting that massive chest as his boner strained against his bathrobe. “You might think you’re big enough,” Lav purred, “but if one of us has the chance to get well and truly big, you can bet your flank that I’m going to see how far I can push you. At least for tonight.” He licked his lips and reached up with his free hand to undo the tie of his robe. “I want to see just how big I can get those arms to swell up. How big and soft and strong I can get your chest, your thighs, your ass. And from the way you’re not pushing me off - “

His robe flew open, and his shaft burst free. On any normal stallion, it was a handsome one, a long, throbbing rod of meat a good fourteen inches in length. It was girthy, too - Lav had never been able to fit one hand’s fingers all the way around it - and absolutely drenched in pre. He grunted, his hips pushing forward reflexively as his stiff flare slapped wetly against Cheer’s enormous cleavage of muscle.

A smirk crossed his face. “ - I can tell you that you like it, too.”

An enormous ripping sound answered him. Lav’s eyes widened when he felt something beneath him suddenly shove upwards with a huge amount of force. He grunted, sliding forward and falling against Cheer’s massive torso as his huge coltfriend’s sweatpants tore right through his pant leg. Lav’s cock found itself trapped between his own clean-cut pecs and Cheer’s bulging, flexing chest, his balls resting atop his coltfriend’s tree-trunk thighs. Something bounced behind him, shoving firmly against his rear. And then Lav could feel it: something wide, warm, and heavy leaning against his lower back. He glanced up at Cheer, grinning victoriously.

“Looks like somepony wanted to come out to play.”

Cheer just sighed. “Now I’ll need new pants, too,” he grumbled. But he didn’t look irritated. Somewhat pleased, in fact, and there was a definite lust in his gaze that Lav couldn’t wait to investigate.

Lav didn’t need to see it to feel it. Cheer’s massive length was almost an entity in itself. sliding up between his tight butt cheeks and pushing them firmly apart. He leaned back a few inches, steadying himself by curling his fingers around a tuft of Cheer’s abundant chest fur. In what felt like no time at all, he could feel the round, throbbing curve of his coltfriend’s medial ring pressing against the small of his back. Eagerly, he turned around to see the evidence of Cheer’s arousal.

And wow, what evidence it was. Lav kept his hips facing forward, but had to twist around halfway to be able to see it all. He wolf-whistled, then curled an arm around it. Cheer was big: nearly three feet of massive stallion goodness. His throbbing shaft towered up nearly to Lav’s muzzle, and was just about as wide as his head. The curve of his flare was smooth; his medial ring bulged to almost the radius of a basketball. Had Lav flexed one of his biceps, it would have maybe come up to around two-thirds of Cheer’s width; the only reason his massive coltfriend’s cock didn’t dominate the entirety of his body was that the rest of him was just so utterly big as well.

It was absolutely drenched in pre. Lav may have been playing with him for a mere minute or two, but he had little doubt that if he bothered to go through the scraps of Cheer’s former pants, he’d find everything below the thigh drowning in the musky scent of his warm, thick precum. Cheer’s flare twitched, idly splurting out a glob of precum the side of Lavender’s fist. It splattered right on Lav’s muzzle, staining his fur dark. That volume alone many most other stallions’ entire orgasms look small.

”So I was right.” Lav hugged Cheer’s magnificent cock to his side. He nuzzled against it softly, filling his lungs with its scent as his hand wandered down to the base. His fingers curved around the circumference of Cheer’s enormous balls, each one the size of a small beach ball and absolutely groaning with seed. “You were pent up.”

Cheer groaned. His big hands slid up his thighs and squeezed. He bit his lip as his wings twitched behind him, flaring out as he made every effort to control himself. “It...wouldn’t have been a problem.”

“A problem,” Lav scoffed. “As your doctor, I feel obliged to tell you that proper sexual release is anything but a problem.” Another healthy spurt of pre from Cheer’s tip splattered all over his chest, and he beamed. “Especially not for you.”

“Mm.” Cheer grunted noncommittally, but his cheeks were a bit red. His fingers flexed, then twitched up around Lav’s rear. Lav turned back and flexed his shaft, pressing it harder against Cheer’s stone-cut abs as the big stallion slid his hands over his Cutie Marks. Cheer gave his tight rump a squeeze and Lav grinned.

“Not nearly as thick or beefy as yours,” he said, eyeing the curve of Cheer’s huge bubble butt around his thigh with some envy, “but good enough. And I think you just want something to cuddle.”

Cheer opened one eye and raised an eyebrow at him. “...Maybe,” he rumbled. Lav just smirked and adjusted his position atop Cheer’s lap. The big pegasus’ cock bobbed steadily behind him; once every few seconds, it’d prod against the back of his neck, leaving a fat smear of precum on his fur. Lav’s fingers trailed up around Cheer’s massive bicep and gave it a squeeze. His fingers couldn’t even reach halfway around. Catching his interest, Cheer gave it a flex as he squeezed tighter around Lav’s flank. Lav couldn’t help the gasp of arousal at the sight of the magnificent bicep bulging up to nearly twice its size and then staying there, groaning with mass and power.

“Showoff,” Lav teased. His own cock twitched between Cheer’s pecs. “You’re just a big horny stud.” He gave Cheer’s pectorals a squeeze and darted forward to plant a kiss on the big pegasus’ lips. “I’ll bet you’ve just been waiting all day to get off.”

“I’m the horny one, huh?” Cheer said. He chuckled. “You’re the one twitching like a rabbit.” As if to make his point, he gave his huge, rounded pecs a flex. Lav gasped in pleasure as the tightness of Cheer’s pecs surrounded his member, plump softness giving way to a steely canyon of muscle that took his arousal and just squeezed. A fat glob of pre burst from his cock, leaving a tuft of Cheer’s chest fur sticky with lust.

Now it was Lav’s turn to blush. “Damn it. I can’t help it. You’re just that much stallion.” He gave his hips a pump, grinding his cock further upward between those two slabs of muscle. As he thrust, Cheer alternated flexing and relaxing his chest, the tightness of his enormous pecs growing a little bit more each time. His fingers dug in deep to Lav’s rump, squeezing his Cutie Marks as the smaller stallion slowly slid further forward. Before long, Lav had both hands around Cheer’s massive waist, his throbbing cock trapped between their two hot bodies. “You’re a giant, and I’ll be damned if I let a single inch of that hulking body go to waste.”

Cheer blushed again. Lav felt the tip of his coltfriend’s flare lean against his neck - and stay there. “I’m not that big,” he said. “There are some stallions bigger than me.”

“Not in my fantasies, they aren’t.” Lav smirked up at Cheer and drew a hand down his bulging arm. “And besides, they’re not here with my dick between their pecs, are they?”

Cheer chuckled. “I suppose not.”

Lav shrugged off his bathrobe and let it fall to the floor. His pale-furred body was laid bare to the room, the lean muscles of his swimmer’s build flexing and glinting with a thin sheen of sweat. “And I’m right here, if you’d like to take advantage of that.”

Cheer met his smile and smile back. His hands traced up Lav’s back, slowly, gently. His big fingers made small circles beneath the smaller stallion’s shoulderblades, massaging and loosening the muscle there. All the while, Lav continued to pump his hips forward and backward, humping Cheer’s pecs with a steady, throbbing rhythm.

Cheer’s fingers came up just beneath the bottom of his flare, paused, and then circled around it. It’d already been leaning against Lav’s back, but now Cheer pulled his shaft forward and down, pressing Lav firmly against his wide chest. Lav was grinning like a madpony, even though he was slightly squished in this position.

“What’s that?” Lav said, his voice slightly muffled against Cheer’s soft pec. “Is the big pegasus too horny to care? Or is he just happy to use a toy when it’s offered?” He gave his tight rump a wiggle along Cheer’s base, and felt almost gleeful when he felt the titanic shaft rumble and lurch in response.

Cheer began to pump his hands up and down his shaft, which was so slick with pre as to reduce the friction to nearly zero. The scent of his muscles, of his sweat, of his lust, filled Lav’s nostrils so thoroughly that every breath he took stunk of Cheer’s masculinity. Cheer groaned, pumping his hips lightly and causing Lav’s whole body to shift down toward his crotch. As he pulled back into the loveseat, Lav’s body pushed back up, shoving his cock back between Cheer’s enormous pecs.

Up and down they went, Cheer jerking himself off with a combination of his own big hands and Lav’s entire body. Lav grunted, twisted, writhed in Cheer’s strong grip, frantically humping the big pegasus’ abs and pecs for all he was worth. His lean muscles flexed and twisted atop Cheer’s. He could feel every throb of arousal through the magnificent tool pressed into his back. He could hear - no, feel Cheer’s heartbeat, his head pressed right up against his chest. He could feel his back and shoulders, absolutely covered in Cheer’s pre and making for the perfect half of a fleshlight as his shoulderblades flexed and squeezed. He could feel the churning, the sloshing of Cheer’s massive nuts, which had now swollen up to the size of small beach balls and were more than ready to spill their side -

With a pair of grunts and cries, the two stallions came together. Lav came right onto Cheer’s chest, eight healthy spurts of cum that would have left most other stallions jealous, and that would’ve easily filled any liquid measuring cup. Fat gobs of spunk spattered onto Cheer’s fluffy chest, matting its fur and staining it a bright, creamy white.

Cheer’s orgasm, though, was orders of magnitude larger. He grunted, then groaned, and then roared, albeit softly. Every muscle in his body bulged hugely, squeezing Lav tighter against his chest as his cock bulged with the force of orgasm. His entire shaft lurched and spasmed, splattering Lav’s back, head and Cheer’s own chest and face with quarts - or even gallons - of jizz. It got everywhere, huge ropes of spunk rocketing out of the big stallion’s tip and covering everything before it with his thick cream.

Cheer’s orgasm went on for a good thirty seconds longer than Lav’s. But when they both finished, their reactions were much the same. Cheer slumped back in the loveseat, groaning; Lav did the same on his chest, his cock steadily softening between their warm, sweaty bodies.

Lav grunted, but then smiled when he felt Cheer’s massive arm curling around him. “Mm,” he murmured, snuggling into the big stallion’s enormous, cum-stained, and almost soft chest. “Now that was a much-needed release.”

He could picture Cheer blushing when he replied, “I suppose it was.” Cheer chuckled softly as Lav nuzzled against one fuzzy pec, the slab of meat itself larger than his entire head.

“I’ll be back to normal size tomorrow morning, probably,” Cheer said. His big arms curled tighter around Lav’s back, pressing him close. His fingers did wander a bit, though, playfully teasing against Lav’s tight rump.

Lav smiled as he said, “So? I can just pump you back up to this size the next time.”

“The next time, hm?” Cheer’s voice was chiding. “After you help me clean up the mess we just made, right?”

Lav chuckled, a bit awkwardly. “Sure,” he said, petting Cheer’s bulging arm. “Sure thing.”
