The shower curtain was abruptly yanked open, making Jake pull back in surprise as he wiped his dripping fringe from his eyes. In front of him Guy's son Simon was staring incredulously at him.
"What the hell, Jake...? Why are you having a shower in our house?"
"I just... er..."
Unable to think up a plausible explanation on the spot, Jake switched off the shower off and grabbed the towel he'd left on the side of the bath.
Eventually he settled on, "I was helping your dad with... something... and I got mess all over me..."
"Where is dad?" Simon asked impatiently.
"He's using the other shower... the one in his bedroom..."
Just then Guy called from along the corridor, "Simon! I didn't know you were due back so early..."
"Yeah, obviously," Simon snapped, stepping out into the corridor to eye his father suspiciously. "What's been going on in here? Why are you guys both taking a shower?"
"We were... ahm... getting a bit sweaty..." the plumber floundered, as Jake followed Simon out of the bathroom wrapping the towel around himself.
Simon looked from his dad, still pulling on his dressing gown, to his former school friend. There was a shiftiness to them that made his forehead furrow with mistrust.
He muttered, "What have you guys been up to...?" as he noticed pink scratch marks across his dad's hairy chest and that Jake's shoulders were red with the indents of dug-in fingers. "Have you guys been... oh my God... you've been having sex, haven't you?"
Jake gaped wide-eyed at Guy - wondering how the hell would Simon be able to figure that out so quickly - and Guy looked in horror at his son, stammering, "Having sex...? What d'you mean...?"
Simon pushed passed him and into his bedroom. "There's a woman in here, isn't there? What the hell have you two been...?"
His voice trailed off as he saw the mess in his dad's bedroom. There was no woman in sight but the two men's clothes were haphazardly strewn around the floor as if discarded in a flurry of impatient passion. The bedspread was in wild disarray where bodies had clearly been wrestling and cavorting, but worse than that the sheets were daubed with brown smears and handprints.
"What is this?" Simon gasped. "Jesus... it stinks!"
His eye fell on a line of thick white splashes reaching across the bed and several feet up the wallpaper. It was unmistakably semen which had been shot from a cock with great enthusiasm.
"You have been having sex," he mumbled with disbelief. "But with each other!"
"Look, I can explain..." Guy said but was unable to continue when he realised he couldn't.
"The smell!" Simon winced. "All that brown stuff... is it you guys' shit?"
"Things got a bit... you know... nasty..." Jake chipped in. And then, with a snigger, added, "That's what made it hot!"
Simon flew at him, eyes blazing. "When you fuck my dad up the butt, you don't get to say it's hot!"
Jake just looked back nonchalantly, like a bullmastiff who has just been yapped at by a Pomeranian. "Actually, he mainly fucked me, so most of the shit is mine... and the trail of spunk definitely is!"
"Jake, I think you should go," Guy said. "You're not helping, buddy."
"Okay, cool... whatever," Jake shrugged, and tossed his towel on the floor to start picking up his clothes.
He made no attempt to conceal his nudity as he grabbed his stuff from where it was scattered around the room. He stuck his firm bubble butt out as he bent low to retrieve things, flashing Simon an eyeful of his swollen man-cunt still oozing with his dad's cum. He smirked as he strutted about, letting his thick cock and low-hanging balls swing around between his muscular thighs, while clearly delighting in parading his gym-chiselled six-pack and biceps.
"Your dad fucked me as a dude," his triumphant grin told his former friend. "You can't think of a body like mine as a chick's."
Then, with a final sneer, he left father and son alone in the bedroom as he went downstairs to pull his clothes on and let himself out.

"You left your mobile at my dad's," Jake announced as Guy opened his front door. Standing outside in his tight jeans and motorbike jacket, the well-built twenty-year-old looked little short of stunning.
"It's good to see you, Jake," Guy smiled, grabbing the phone. "You wanna come in for a beer or something...?"
"Yeah, or something," Jake chuckled, as he followed Guy into the house.
"Thanks for bringing it over," Guy said, walking through to his kitchen to get a couple of beers out of the fridge. "You on your way somewhere?"
"Naah... I just fancied a look out... needed a bit of air."
Guy uncapped the beers and passed one to his closest friend's son. He'd always had a soft spot for Jake. When he used to pick him up from school with his own son Simon many years earlier, he'd grown fond of Jake's playfulness and his mischievous sense of humour. Now that he was a young man at university, he admired Jake's developing sexual confidence. Unlike Simon, who could be awkward around girls, Jake not only had a long-term girlfriend but made no secret of the sex he enjoyed with other bisexual boys.
"Last time I saw you," Guy said after taking a swig from his bottle, "our banter got a bit raunchy..."
Jake grinned back at him, drinking his own beer. Guy was his dad's favourite fuck-buddy and a few weeks earlier when the plumber had been around at his house for a few drinks, he and Jake had had fun talking dirty about each other's bum smells. They'd had a grope of each other's hairy arse-cracks and had sniffed the stinky fingers their fumblings had produced, and it had been clear from their flush-faced excitement that both men had ended up extremely turned on.
Guy smiled and continued, "I'm sorry if I took things too far... I get a bit carried away sometimes..."
"Come on, Guy... sniffing each other's butts was hot," Jake chuckled, hanging his leather jacket on the back of a wooden chair. "And if you ask me, I don't think we took things far enough..."
Guy grinned more broadly. "Yeah?"
"Yeah," Jake smiled. "Stink can be fun."
Then the younger man said, "Actually, can I use your loo? I really need to take a dump."
"Be my guest," Guy nodded. "Follow me upstairs... I'll show you where it is..."
Jake had been around to his friend's Simon's house so many times he could have found the bathroom blindfolded, but he followed the larger man up the stairs while checking out his big round rump so temptingly filling the seat of his jeans.
Guy went into the bathroom and put the toilet seat down ready for Jake to perch his bum down to take a crap.
"It's all yours," he smiled, showing no signs of leaving the room to give his guest privacy.
This was better than what Jake had been hoping for, and he quickly pulled down his jeans and bright stripy boxers and sat himself down on the pan.
His long thick cock drooped downwards into the bowl. As he let out a first fart it started slowly hardening and was soon rising conspicuously upwards from his two fat hairy balls.
He grinned up at Guy. "You know when you're straining to drop one and you start getting a hard-on from it...?"
Guy laughed at his young friend leaning forwards to open his bowels. "Too right, mate. You know, your cock's even bigger than your dad's."
"Yeah, and my butt's a lot cuter," Jake smirked, as a thick rope of his shit dropped into the bowl so heavily that the back-splash soaked the cheeks of his bum.
"Oh wow!" Jake guffawed without the slightest trace of embarrassment. "Talk about a poonami!"
Guy sniffed the air and winced as the full ferocity of the younger man's outpouring hit him.
He laughed, "Aw fuck, that's rough! Your butt might be cute but... bloody hell, Jake! It kicks out the mother of all stinks!"
"Yeah, my dumps are really smelly," the university student beamed, as if proud of the rank cloying odour his arse had just produced. "I dunno why but they reek to high fuck."
Guy noticed that the younger man's cock was now almost fully hard. It curved upwards from the closely trimmed bush of his pubes, and his foreskin had retracted enough to expose the blunt slitted tip of its large purple head.
"Are you on full bone, mate?" Guy smirked down at him.
"Just about, yeah," Jake grinned back, letting rip with another trumpeting fart. "Trouble is, the stink's kinda sexy... it reminds me of having some dude behind me, doing me hard!"
"Aw really?" Guy chortled. "Is this how your room stinks this when you're gettin' your arse bummed...?"
"Too right!" Jake laughed, as the memory made his cock stiffen up to full size causing his helmet to pop out through the stretched ring of his foreskin. "I love it though... it's really horny when boy-sex gets a bit brown!"
"Like a shitty fuck, do you?" Guy asked with a sly leer.
"Yeah, I love it!" Jake guffawed. "Especially when it's dead rough and fast and his cock gets covered in my crud!"
