The next morning, Mark woke up with a tired groan, the intense memories of the night before rushing back to him. He lifted his head and glanced at the clock before his eyes shot wide open, realizing he had overslept for work for the first time in years. He quickly jumped out of bed, rushing through his morning routine. As he drove to work, Mark’s mind couldn't help but wander back to the toy, and the sensations it had given him. He felt both satisfied and slightly guilty, like a teenager who had just discovered masturbation for the first time.
Arriving at the office, the first thing Mark saw when he stumped down into his seat was Jake’s annoying look beside him, coupled with a knowing grin. ‘Well, well, well.” The younger man drawled, his eyes flicking to the dark circles under Mark’s eyes, the slumped shoulders, and the exhausted expression. “Someone had a wild night, didn’t they? First time I’ve seen you late for work, old man.”
The comment brought a fresh wave of heat to Mark’s cheeks, and he gruffly muttered something about insomnia. He made a point to ignore the stupid grin on Jake’s face and focused on his computer the entire morning. But the memory of the fleshlight’s warm embrace lingered in the back of his mind, the intense attention his cock received the previous night left it tingling in pants distractingly even now.
By the time lunch break came, Mark frowned in annoyance as Jake cornered him in a quiet corner from other workers.
"So, how was your little... 'stress relief' last night?" Jake winked, his voice filled with smugness and a too-eager curiosity.
“It was fine,” Mark grunted curtly, hoping to deter further questions, his hand tightening around his coffee mug. The black liquid was strong and bitter, but it couldn’t quite chase the lingering drowsiness away for Mark. He knew an intense orgasm for a man his age could leave some lingering tiredness, but he had not anticipated the sheer draining power of the toy.
“That’s it? Just fine? No way, I saw how drained you looked when you came in, man!” Jake leaned closer, his eyes shining with excitement.
Mark took a sip of his coffee, trying to ignore the smug look on his friend’s face. “Fine, it worked better than I expected. But it’s none of your business,” Mark said, his voice low and gruff as his face got slightly redder. He had almost forgot how annoying and persistent Jake could be when he was onto something. Still, the younger man was showing too much interest for this particular intimate topic.
“Oh, but you know. It’s kind of my business…” Jake said in a low, conspiring tone.
“What the hell do you mean by that?” Mark’s eyes narrowed as he set down his coffee, his curiosity piqued despite his irritation.
Grinning smugly when he knew he got Mark’s attention, Jake whispered in a volume that only Mark could hear. “You see, that technology miracle isn’t on the market yet… it’s actually a prototype my genius of a brother had made! And I might have played some parts in its creation. So since you’re such a cooperative tester, I might as well collect some valuable user feedback!”
Mark blinked at Jake’s hushed and excited words, then blinked again. He distinctly remembered Jake’s younger brother while they were in college, a quiet and lanky kid with messy hair and big glasses. Then he digested what Jake had just told him, and…
“You used my dick as your lab rat!?” Mark grabbed the younger man’s wrist in a death grip as he sputtered indigenously, his bearded face flushed red in a different reason now.
“Hey, rude! I wouldn’t have given it to you without basic safety tests and clinical trials, you know!” Jake laughed, trying to free his wrist from Mark’s grip. His eyes sparkled with mischief. “But seriously, we need feedback to make it market-ready. You’re the first outsider to get a taste, so your input is gold! And don’t even try to deny you enjoyed it!”
The room spun around Mark as he processed the information. His private part had become an unwitting participant in some kind of underground tech experiment. His mind reeled with questions about hygiene, consent, and whether he’d just had the most intense orgasm of his life with something that could have exploded. But amidst the chaos, one thought remained clear: he had indeed enjoyed it.
Apparently, his silence and expression was enough confirmation for Jake, as that damn smug grin of his grew even wider. "You’re pretty cute when you refuse to admit I’m right, you know that?"
Mark's anger and embarrassment were warring inside of him, his grip on Jake’s wrist loosened slightly. "You’re an asshole Jake,” the older man finally grumbled without looking at his friend in the eye.
“So, feed back? Pretty please?”
Jake’s insistent question snapped Mark out of his thoughts. He took a deep breath and glanced around, making sure no one was close enough to overhear. The break room was abuzz with the usual midday chatter, oblivious to the juicy conversation they were having. Mark let out a tired sigh, resigning to his fate as a reluctant test subject.
“Not in here, you idiot!” Mark hissed, glancing around the room. “I’ll mail it to you or something, alright? Now shut up about it!”
Jake’s grin widened as he nodded in satisfaction. “Great! I knew you’d see the light. And don’t worry, I’ll keep your secret. But, as a token of appreciation for your... participation, how about I show you some more of its features after work today?”
The words, whispered with promise and something else, made Mark’s heart stutter in his chest. He had always been close with Jake, being college roommates and all, but this was a new level of intimacy, one that made him feel both nervous and excited. He stared at Jake’s handsome, slightly mischievous face, the same face that had gotten them into and out of trouble so many times over the years.
Mark was a private man, rarely went out for hookups or one-night stands, but something about Jake’s offer made his pulse race. Was it the thrill of trying the toy again? The curiosity of the features? Or was it just because of Jake? Whatever it was, Mark felt his spent cock stirring in his pants at the thought alone, and that was answer enough. He cleared his throat and nodded subtly.
“This stays between us, understand?” Mark whispered sternly.
Jake grinned and gave the older man a mock salute before pulling his hand away. "Your secret's safe with me, Marky boy," he teased, using a nickname that Mark hadn’t heard in years.
They didn’t speak for the rest of the day, or on the way as Mark drove them to his apartment. His mind was a whirlwind of thoughts, trying to process what he had agreed to. But every time he glanced at Jake’s way, his cock would throb in his pants, reminding him of the offer that had been made.
As soon as Mark clicked the door shut behind them, Jake guided him toward the bed with an almost demanding push, eyeing the sleek black toy sitting innocently on the night stand. Mark's heart thudded in his chest, his nerves tingling with a mix of anticipation and trepidation. He watched as Jake picked up the device, his thumb tapping the screen with a knowing smile.
"Let me see… it recorded your orgasm from last night with an intensity of 9.2 out of 10, and the duration was quite impressive too," Jake said, his eyes scanning the screen with a smirk.
“What the…!?” Mark’s voice cracked as he stared at the toy in Jake’s hand. The thought of the device keeping score of his personal moments made him feel exposed, but hearing the numbers also made him aroused in a weird way. He cleared his throat and crossed his arms, trying to regain some semblance of composure. “So, what’s the plan?”
Jake looked at his way with a grin. “Well, why don’t you get naked and comfortable for start, and I promise to pump that orgasm intensity number up tonight!” He said with a wink. Mark felt his cock stir at the words, and he couldn’t help but obey his younger friend’s words despite his reservations.
They have seen each other naked plenty times while they were college roommates, but it felt different now. The atmosphere was charged with something more than just friendship, something more intimate than Mark was comfortable with. And as he sat there on the bed, his body exposed and cock already half hard, Jake’s eyes roaming over his hairy chest and the trail leading down to his crotch, it dawned on Mark that he was about to have an experience that was going to be more than just a simple round of testing.
Jake knelt between Mark’s spread legs on the floor, his handsome face a mix of concentration and excitement. Mark felt his cock twitch in response to the hungry gaze. He had never felt so... exposed before, especially in front of Jake. The toy in the younger man’s hand hummed to life, and Mark watched, fascinated, as the screen lit up with a series of pulsing lights and graphs.
“Alright, big guy. Deep breathe while I get you ready,” Jake grinned up at the older man before his hand wrapped around Mark’s cock without warning, the other holding the fleshlight in position. Mark’s breath hitched as he felt Jake’s hand gently pumped him to full hardness in no time. The sensation of his friend’s touch combined with the anticipation of the toy’s embrace was almost too much to handle.
“Don’t get too excited yet,” Jake’s voice was a tease as he lined up the opening with Mark’s now fully erect cock. His hand remained wrapped around the base of Mark’s shaft, keeping the rod pointed up as if preparing him for what was to come. Mark’s eyes were glued to the toy, the sight of his cock about to disappear into the warm, inviting hole again making his abs tensed with anticipation.
Then Jake slid the toy down to his base in one swift move without warning, making Mark gasp loudly. The probe inside was already active, flicking near his frenulum with deadly precision. Mark felt his body jerk as the sensations built rapidly, his mind racing as he struggled to keep his moans at bay. Jake chuckled at his reaction, his own excitement clear in his eyes.
“See? It remembers your sweet spot after only one session,” Jake whispered, his eyes dark with pleasure at Mark’s reaction. His other hand slid up Mark’s hairy stomach gently, making the older man’s skin tingle. The fleshlight’s inner walls began to pulse and contract around his shaft, the probe now flicking faster than ever, and Mark could feel his orgasm building already.
“Jake, I…” Mark’s desperate word made Jake chuckled in amusement, his hand holding the humming toy firmly in place against Mark’s groin.
“That good, huh? But I haven’t even turned on the full customization mode yet,” Jake said with a devilish smirk. He tapped the screen of the fleshlight, and Mark felt the walls of the device tighten around shaft, massaging and vibrating in a more intense pattern of contractions.
“Oh fuck, Jake!” Mark groaned, his eyes rolling back in his head as the toy took over his body. The pleasure was so intense that he could feel his cock twitching like a beating heart. That damn probe was dancing over his sweet spot relentlessly, and he bit down hard on his bottom lip to keep from crying out.
“Hang on a bit longer, old man. Now, let me use the edging mode that you so cowardly rejected last night,” Jake said with a grin that made Mark’s stomach flutter. The toy’s tempo immediately changed, the contractions becoming slower, the vibrations more gentle, and the probe retreating slightly. Mark’s body tensed, desperately trying to hold back the wave of pleasure that threatened to crest.
“Initiating Edging Mode. Cycle one.”
The toy’s AI voice announced, and Mark felt the vibrating around his cock switched to a slower, more teasing rhythm. Teasing rather than overwhelming. Jake’s hand remained on his stomach, his hand rubbing small circles on his belly bottom sensually that drove Mark insane.
“You know, Mark, edging is like brewing fine wine. You’ve got to savor it, let it build up to that perfect moment until you can’t hold back anymore,” Jake explained, his eyes never leaving the screen of the fleshlight as he fiddled with the settings. His voice was filled with a mix of excitement and professional pride.
But the words weren’t registered by Mark as he was too occupied by the sensations. The toy’s opening has clenched tightly around the base of his cock, effectively keeping his orgasm at bay as it delivered wave after wave of pleasure without letting him cum. Mark’s hips began to thrust upwards, seeking relief, but the device was designed to keep him right on the precipice, and Jake was controlling the pace.
“Edging Cycle 3 initiated. Intensity increasing by 10%.”
The toy’s voice was almost a purr, and Mark’s breath grew ragged as he felt the contractions tightening, the probe flicking faster. His cock was begging for release, but the device had other plans. He was at Jake’s mercy, and the younger man was clearly enjoying every second of it.
"Jake...please," Mark moaned, his hands gripping the bedsheets tightly. The younger man's eyes flicked up from the screen, meeting Mark’s pleading gaze with a glint of satisfaction.
"Already begging on cycle 3? I thought you’re tougher than this, Marky boy,”
Jake’s voice was a teasing whisper in Mark’s ear, his breath hot and tickling against his skin. Mark couldn’t believe the toy had so much control over his body, and even less that Jake was toying with him like this, enjoying his torment. He wanted to protest, but the words were stuck in his throat as another wave of pleasure crashed over him.
The toy kept him on the edge by alternate between gentle strokes and tight squeezes, each pulse of pleasure bringing Mark closer to his breaking point. His cock was a throbbing, leaking mess inside the toy’s warm embrace. The sensations grew stronger, and Mark could feel the pressure again building, his body taut like a bowstring.
“Make me cum…!” Mark gasped, his body covered in sweat and trembling lightly.
“Sorry, buddy. The toy doesn’t recognize voice control right now because I have it on manual mode,” Jake smirked, his eyes still on the screen as he tapped and swiped through the settings. “Hmm, let me add a bit more punch on the right spot…”
The probe inside the fleshlight immediately responded, its flicks becoming more intense and focused on the sensitive spot under Mark’s cockhead. The older man’s breath caught in his throat, his eyes watering slightly as the pressure grew unbearable. Jake watched him, his hand moving faster on Mark’s abs, his fingers playing with the trail of hair leading down to his groin.
“You still look so hot and rugged after all these years, Mark,” Jake murmured, his eyes roving over Mark’s muscular physique. The sensual words almost push Mark over the edge, but the toy expertly clenched around his base at the last moment, denying him the release once again.
“Edging Cycle 7 Complete,” the toy’s AI purred, and the intensity dropped immediately. Mark’s body was a writhing mess of need, his cock pulsing with desperation. He didn’t know how much more of this he could take.
“Jake, for the love of god, please, let me cum already!” Mark begged, his voice strained and hoarse from his repeated attempts to hold back.
Jake's smirk grew wider, his eyes gleaming with delight at Mark’s desperation. He leaned in closer, his breath hot against Mark’s ear. “But where’s the fun in that? Besides, I want to hit cycle 10, let’s my record! You can handle it, I know you can,” he whispered, his hand sliding down to Mark’s swollen balls and giving it an encouraging squeeze.
“Jake!” Mark's voice was a strangled whine, his eyes squeezed shut as he tried to endure the relentless cycle of pleasure and denial that the toy and his friend were putting him through. His body was trembling, and his cock was so hard it felt painful, trapped in the vice-like grip of the relentless toy.
Jake finally take pity on his friend, his own cock rock hard in his shorts after watching Mark’s delicious torment. He leaned in closer, his breath warm against Mark’s sweaty neck. “Alright, let’s go for the grand finale, shall we?” He tapped the screen again, and the toy’s intensity shot up to maximum.
Every part of Mark’s cock got assaulted with pleasure as the toy went full throttle. The walls tightened and milked his shaft, his cockhead got bombarded by deep vibration, and that damn probe... it was like a tiny tornado, relentlessly buzzing and rotating against his frenulum. Mark’s body was a live wire, his hips bucking uncontrollably as he approached the edge of oblivion once again.
Then the tight grip around his base loosened, Jake’s hand gave his balls a final squeeze. Mark’s body arched off the bed as the fleshlight’s walls contracted in rapid succession around his cock, the probe delivering the final, precise strokes to his sweet spot that sent him hurtling over the edge. He came with a roar, the semen spurting out of him in thick, hot ropes that flood the inside of the device.
The sensation was unlike any orgasm Mark had ever experienced. It was as if the toy was milking him dry, drawing out every last drop of pleasure. His entire body convulsed, the muscles in his body and legs clenching as he shot his pent-up load into the demanding toy.
“That’s it, Mark. Give into it,” Jake encouraged, his voice thick with arousal as his hand kept up the squeezing on his balls.
Mark’s body trembled as he rode the most intense climax of his life. He could feel the fleshlight’s walls pulsing around him, mimicking a perfect, tight tunnel as he shot his load. The probe didn’t let up, continuing its relentless dance on his frenulum all the way through his orgasm, making his body jerk and tremble.
“Good boy,” Jake murmured, watching the older man’s climax with a mix of fascination and satisfaction. Then, Mark’s body finally collapsed back onto the bed, his chest rising and falling rapidly as he struggled to catch his breath. The toy had done its job, leaving him boneless and utterly spent.
Jake’s thumb tapped on the screen, his eyes flicking to Mark’s blissfuly face before finally looking down. The reading showed an orgasm intensity of 9.8 out of 10, and Mark felt a strange sense of pride at his friend’s impressed look. “Damn, you really enjoyed this one, Marky boy,” Jake said with a cocky grin, shutting off the toy and slowly pulled it off Mark’s now-soft cock with a wet pop.
Mark could only moan weakly in response, his body still twitching from the aftershocks of his climax. His cock was red and sensitive, and he was pretty sure he wouldn’t be able to move from the bed for the next few minutes.
Then he felt Jake’s body pressed against his and the younger man placed a soft kiss on his lips. “Looks like my little demonstration worked out just fine,” Jake said with a smug smile, holding up the fleshlight to show Mark the glowing 9.8 on the display.
The sight of the number made Mark’s cheeks burn, but he couldn’t help the small smile that tugged at his lips. “You’re one sadistic son of a bitch, you know that?” Mark panted out weakly, his chest still heaving from the intense climax.
“It’s called aiming for the best result, my friend! And my brother has been working on an extension for balls stimulation too, I can already tell that’s gonna make you hit the 10 out of 10!” Jake’s eyes twinkled with devious excitement as he held up the fleshlight, examining the harvest of Mark’s release with a sense of pride.
Mark could tell he’s gonna pass out soon, his body too drained from the intense orgasm. But aside from the mind-melting orgasm, Mark could still feel Jake’s earlier kiss, and it was burning hotter than the aftermath of his climax. He looked over at Jake, who was taping away at the toy’s screen to check whatever data it had recorded.
“I wouldn’t mind… letting you test that extension on me,” Mark said, his voice still breathless from the climax. He was surprised by his own words, but the idea of experiencing that kind of pleasure again, especially with Jake’s expert touch, was too tempting to resist.
Jake’s head snapped up from the screen, his eyes widening in surprise before they lit up with excitement. “I’ll hold you up to that, big guy.” His voice was eager, and Mark felt his spent cock twitch at the prospect despite the exhaustion.
Then Mark’s eyes fell closed, and his head lolled back into the pillow as he lost the battle against consciousness. Jake chuckled, placing the toy aside and climbing into the bed, curling up against Mark’s side as the older man’s breathing even out. The throbbing in his own groin could wait, watching his usually stoic friend fell apart in his hands was a prize in itself.
