You were just taking a shower after a workout, when some big asshole came and sat on you. Then you get power bottomed.


You were just sitting on the bench in the shower stall, enjoying the post-workout high. Endorphins pumped through you with every heartbeat, bringing a gentle, quiet ecstasy into your aching limbs. You weren't much of a bodybuilder yet, straining to lift a 15 pound dumbbell while others were pumping two or three hundred pound bars, but you remained positive. After all, this was one of the best gyms in the city You'd be a champion one day, or die trying.

You had no idea how long you'd been in there, just enjoying the warm water pulsing from above. All you knew was, you were content. You were so content, that you were blissfully unaware of footsteps stomping down the tiled corridor outside. For all you knew, those thuds could be the beating of your own relaxed heart. But, as the shower curtain slid open, you realized you were all to wrong.

There in the doorway stood one of the biggest beasts you'd ever seen. It wasn't a man; More like a wall of meat blocking the doorway. Two massive pecs, a tight and rounded gut, and - You gulped - A twelve inch penis dangling in front of two apple-sized nuts. He was at least 7 feet tall, with the upper part of his head obscured above the doorframe.

His thick brown fur was already soaked, and for a second you wondered why he was here, if he'd already taken a shower. Maybe he left something behind? Then his ragged breathing hit you - And the smell! He's clearly been hitting the gym today, hard. His body odor is hot and smoggy, overpowering the tropical scent of your body wash.

The smell only got stronger as he took a step in, hunching over to get his head past the low ceiling. You only see his face for a split second, long enough to confirm his species as a bear, with blue eyes and a beard hemming his face, before he turned ponderously around. Was he leaving?

No. NO! You stared up in horror as he began lowering himself down. He must not have seen you - Two heads shorter, sitting down, how could he have? You tried to shout, to let him know you were there, but your cry got stuck in your throat. His butt was -so wide-! You'd seen quite a few bubble butts in your day, mainly on gay porn forums, but none of them were quite as impressive as this.

Even with his huge body, this thing was out of proportion. Each cheek was the size of a medicine ball - You could spread your arms out wide and you wouldn't be able to reach around them His hips flared out slightly to accommodate it, and for a split second, you wondered where this beast was able to find pants to fit.

That second passed, along with your chance of shouting for help, when he sat down on you. One moment, he was slowly lowering himself down, the next - Splat! - The bear's massive ass had slammed down on your chest, pinning you between the shower seat and the wall. You had no idea how much he weighed; You'd never been crushed by a truck before! Somehow, you managed to breathe despite the enormous weight on your lungs. What little energy you could muster, you dedicated to fighting back against your captor, but it wasn't much. Not nearly enough to get his attention. Your pained groans, which he might've mistaken for the seat creaking under him, were drown out as he started singing in a low, rumbling baritone.

"Holy diver, you've been down too long in the midnight sea... Oh, what's becoming of me..."

Your weak squirming elicited no response. The bear probably couldn't feel you beneath the muscle and fat that made up his ass. The smell was almost unbearable now; Thick male musk rolled off him in waves, washing over your body along with the water flowing over his shoulders. You squinted from the spray and looked up. He was just scrubbing himself down, without a worry in the world.

And why should he? He was a bear, a powerlifter, the biggest one you'd ever seen. At his size, you couldn't expect him to have much spacial awareness. What happened to you around him was entirely on your own head.

Water was beginning to pool around your neck now. He leaned forward to wash his back, sending most of the water down his sides, but a small amount collected in the little nook between his ass cheeks and the wall. It was reaching your chin now, and you were starting to panic. You knew it was only a matter of time before your mouth was submerged, and the last thing you wanted was a taste of his BO-ridden water.

Well, the more you thought about it... Gingerly, your tongue slipped between your lips to take a small dip in the water, only to recoil back as soon as it touched the water. A shiver went down your spine. This was so weird - Yet weirdly hot! You felt your cock stirring to life beneath the bear's fuzzy ass. It was getting hard and tight, but crushed between your leg and his cheek, it wasn't doing any good for anyone.

You began squirming again, and with the extra lubrication from the soapy water, managed to slide your bottom half over just a few centimeters. You exhaled deeply as your cock sprung up, sliding forcefully to full mast between his cheeks The bear grunted and moved forward slightly, causing the pool around your neck to flow away. You were actually a bit disappointed, but the taste was still thick in your mouth, so you weren't too upset for the moment.

He didn't seem to have noticed you yet, despite your cock stuck between his cheeks. You'd speak up, but with your diamond-hard erection, you were a little afraid. At over twice your size and weight, if he didn't believe your story... You had no intention of being knotted up into a pretzel and eaten for his recovery snack.

Instead, you tried as hard as possible to soften up. Once your dick was good and flaccid, you'd alert him and explain yourself. Disgusting images floated past your mind's eye, the most horrific and terrible pictures you'd seen on the darkest corners of the internet, and you could feel your cock softening up and shrinking away. You breathed a sigh of relief; You wouldn't be pounded into jelly and spread on a sandwich today.

The relief was short-lived, as he flexed his ass, causing your cock to spring to attention once again. Teeth grit, you tried to focus on unsexy thoughts, but it just wasn't happening. No matter what you tried, your mind always drifted back to the immense pressure on your lap, the off-key singing, and the thick, musky smell coming from the giant bear, who must have been the most ignorant creature on earth to not have noticed you yet.

"Hellraiser... In the thunder and heat..."

He lifted up an arm and began scrubbing away at his armpit. The thought popped into your head, was he even using soap? The musky smell hadn't gone away or even been lessened, let alone replaced by fresh soap. Maybe... Maybe he just wanted to smell musky, and only used the shower to clean off?

That thought was a mistake, as your cock began to ache with hardness. You could almost hear your heart thumping over the spray of the water and your unwitting captor's incessant singing, pumping blood from your body straight into your cock. If it was hard to focus before, now it was impossible. You had to fuck this big brute of a man, even if you died trying.

Your opportunity arose along with him, as he lifted himself slightly off your body, sighing as his vertebrae audibly cracked. Before he could lower himself back down again, you shot to your feet, grabbed his muscular ass cheeks, and spread them apart as far as you could. The tip of your cock poked against his hole, causing it to pucker up tightly and making penetration impossible.

Yelping in surprise, he tried to stand fully, only to bash his head on the low (for him) ceiling. He groaned and crouched back down, pucker loosening involuntarily... And you seized the chance, wrapping you arms around his hips and thrusting your cock into his ass.

"W-what the-" He stammered, arms flailing as they tried to grab you. The most they did was graze your arm, and when that failed, he grimaced and tightened his hole a second too late/

"F-fuck!"

The stimulation caused your cock to twitch, working its way further into his warm depths. You let out a simultaneous moan. Your partner may not have consented, per-se, but he sure seemed to be enjoying himself. Instead of reaching in vain for you, they were propped up against the tiled wall. Water from the showerhead ran down his back and rolled down and round his ass, enveloping your crotch in its damp warmth.

What had started as an accident was quickly turning into the time of your life. You thrust, water slapping around your midsection as it slammed into his ass. This was it; The ultimate experience. You were sure you'd never have a better time, and neither would he. Just as the thought passed through your mind, you felt his body shift, and he let out a low sound, somewhere between a moan and a growl.

One second, you were standing, the next, the bear heaved his body back, pressing you up against the wall of the claustrophobic shower. Squeezed between two immovable objects, it occurred to you that you might possibly be in danger... But as you ground your hips, hilting out inside the bear's tight hole, balls slapping against his ass, you didn't really care.

There was a squishy wall blocking your cock, and as you poked it, he let out a loud gasp. Yep, you realized, that would be his spot. You retreated and thrust into it again and again, eliciting a similar reaction each time. His muscles loosened, and he began to sag against the wall.

"Unh," He huffed, pushing you harder into the wall, "You're big, for such a little guy."

You chose to take that as a compliment, and with both hands, gave his ass a hard clap, causing it to jiggle slightly above the thick muscle underneath. The sound loud and crisp echoed in the small room, slightly dampened by the running water.

More importantly, the bear sagged down at his knees, letting out a sigh as another, splattering sound rang out - The sound of his cum hitting the tiled wall. His body shifted as one arm stopped supporting him, moving down to milk the last drops of cum from his cock. In your position, you sincerely wished you could reach around and help jerk his shaft, or at least be able to see it, but as it was, you had to content yourself with his amazing ass.

He was slumped against the wall, enjoying your prodding in his post-orgasmic bliss, letting out a low moan every time you touched his prostate. Your time was coming soon too, if the rising pressure and tingling in your cock was anything to go by. Gritting your teeth, you tried to hold it in as long as possible, but that didn't last long. Within a few thrusts, you'd reached the edge of the known world, and were about to tip off.

You let out a grunt as you came, eyes rolling back in your head as you blew your load in his ass. Each spurt sent a shudder through your body, your thoughts shattered with every jolt. Time melted away for you as you stood there, balls-deep in some stranger you'd never set eyes on before he sat on your chest. Slowly, your erection softened, and you collapsed onto the plastic seat behind you.

You sat there, gasping for the sweet, musky air, feeling the warm water of the shower wash away your sweat and splatter. Out of the corner of your eye, you noticed the bear stirring, straightening himself up as he stood to his full height, or at least as close as he could get in the small room. Your heart began pounding twice as fast as he turned towards you.

His brown face was tinted red from cheek to cheek, a blush burning across his brutish features. "How... How did you get back there?" He asked, panting.

You just sat there, staring up at him with wide eyes as you tried to think of something to say. What *could* you say? You'd just fucked a man in the ass without so much as learning his name. Honestly, you were lucky he hadn't smashed your face into the wall and called the police yet. You'd have to pick your next words very carefully.

"Wanna come over to my place? I've got Mario Kart."
