Mr. Z watched his picture-in-picture in a stunned silence as his cock erupted an almost painful orgasm into the tight crotch of his jeans. The erotic sight had caught him so quickly by surprise, his penis hadn’t even managed to jump into a hard state before ejaculating at the sight of such a mountainous heap of what he knew to be only a 14 year-old – but oh so developed and hairy jacked-up teenager that was now convulsing and twitching as it swelled to such in-human proportions on the floor at the doorway to his bedroom.

While enjoying his passive, yet overwhelming orgasm, Mr. Z slammed his fist down on the console in hurried response to Chad’s distress.

Wisps of steamy smoke filled the picture-in-picture, as the older man in the dark computer lab watched the increasingly dangerous muscle-teen pheromone level indicator in the top right corner of his screen creep ever-closer to the 100% dead-line level.

Mr. Z’s anti-Flexadrine wafted down across the shivering muscle-teen as it was released from it's condensed capsule at the base of the tiny spy-cam - and the young teenager slowly stopped twitching and convulsing. The older computer genius gazed at the indicator as it stopped at 99% and slowly began to decrease, allowing him to exhale a breath he had suddenly realized he was holding for an incredible amount of time. The man found himself out of breath as he inhaled and exhaled almost to panting, as a result of his unconsciously over-held breath. Sweat dripped from his temples as he withdrew his spy-cam back down and into Drew’s open bedroom window.

Suddenly, Mr. Z realized the argument between Drew and his dad had stopped and the main webcam window showed only and empty room.

Mr. Z tapped the other side of his touch screen and slid back the re-play controls, watching the webcam window play quickly in reverse until both males were back in view. Stopping the recording, Mr. Z then resumed play.

The argument had stopped right as he had released the antidote – the giant boy and his angry dad had stopped their argument as if something had caught their attention. They each sniffed the air and Mr. Z noticed a sudden but obvious bulge in the dad’s crotch, just before the man turned and ran out of the room with the hulking 16 year-old Drew not far behind.

Then Mr. Z looked up at the level indicator and it revealed something he neither expected, nor ever had thought possible. While still green - indicating safe levels of Flexadrinazine - the indicator now revealed that Chad’s muscle teen pheromone level was currently stable at 110%

“That’s not possible…” Mr. Z said aloud.

In the middle of their heated argument, both Mr.Whitley and the hugely muscled 16 year-old musclebound Drew had suddenly sensed a musky odor of mysterious but powerful, enticing erotic strength. Quickly aroused by the scent and unable to resist the pull it had over them, both of the males quickly forgot their angry shouting match and headed off into the direction of the scent.

Reaching the top of the basement stairs and scanning the main floor, overlooking the messed-up kitchen, Mr. Whitley called out. “Hello? What is that!? Where are you!?” Then the man sniffed the air, his eldest – now musclebound teenager, Drew appearing at his side at the top of the stairs.

Drew sniffed the air and then ran down the hall towards the stairs, leading to Chad’s upstairs bedroom. His dad quickly followed him, still sniffing at the air – as if in a trance.

As the huge teenager, Drew and his dad climbed the stairs they became increasingly aroused. The huge teenager, Drew felt his crotch swell quickly, causing his now-enormously thick, long cock to rip and tear it’s way out of his tight sweatpants as he reached the top of the stairs, pausing only long enough to realize his dad was about to see him with his giant muscle-teen erection.

Mr. Whitley climbed the stairs, following his enormously jacked teenage son, Drew so closely – Drew’s own pheromones were inhaled by the man as he took each stair, arousing him. The man felt his erection twitch in his pants as he became confused and disoriented, suddenly urged to look at Drew’s enormous muscle-butt - so tightly encased by his stretched to the limit sweatpants as the giant arousing muscle-teen flexed and tensed under his clothes, at each step.

Mr. Whitley watched his son’s calves – giant enormous ridges flex and strain the fabric as it climbed and he felt as though what he was was now in slow-motion. The man enjoyed the view of Drew’s bulging hamstrings, his flared out quads and back to the incredible sight of his huge muscle-bound bubble butt – that didn’t even jiggle as it so tightly tensed and flexed at each step up.

The hypnotic arousal the man felt then urged him to look upwards and take in the almost impossible sight of his 16 year-old boy’s ultra wide lats that flared out from a waist that seemed far too narrow for such an enormous male. He felt as though he was about to orgasm as he reached the upper stairs, taking in the sights of his hugely muscled teenager that only moments ago he had been scolding for getting so big. So big – o shit, his own son was huge – with giant muscles that were turning him on – had he found his own son, so shamefully sexual?!!

Drew had stopped at the top of the stairs, causing his teen muscle pheromone induced dad to slam into his ass, face-first.

The hard muscle and close proximity to the giant teens pheromones caused the man to gasp and suddenly reach up to clutch Drew’s muscle ass cheeks, only to swipe at the air when Drew lunged forward, into Chad’s bedroom.

Drew had reached the top of the stairs, still sniffing at the air as he felt his enormous and pumped muscles surge with pumping blood in his veins – in reaction to the enticing pheromones of his younger brother. Unable to resist, Drew then dashed into his younger brother, Chad’s bedroom as mixed emotions rushed into his head - feeling confused by the desire to find and pulverize his younger brother for stealing from him - while also feeling incredibly aroused, as if unable to resist the need he now felt to find the kid – if for nothing more than to just see him and what it was exactly, that was drawing him toward his 14 year-old brother with such an uncontrollable erection bouncing out in front of him.

Matt managed to duck and dash behind any available cover as he reached street corners and cross-walks of busy roads – until he could dart across the automobile ridden road-ways in order to continue running. He had been far too embarrassed to be seen in his cum-stained, wet and wrinkled jeans as he ran towards home. Finally making it before his parents arrived home from work, the teenager shook in both nervous fear and aroused delight as he slid the key in the lock and slammed the door shut behind him, panting as he leaned back against the safety of his front door.

Now having time to replay the events in his head, Matt thought of his best friend and his huge muscles – quickly making his previously tamed dick jump back into action, thrashing against his wet jeans.

Matt grabbed, unbuttoned and unzipped his jeans as he took the stairs to his bedroom three-at-a-time. Reaching his bedroom door, Matt tossed off his sneakers and jumped out of his jeans, flicking them up over and into his laundry hamper with one foot as he grabbed at his now twitching erection.

Thoughts of his best friend’s older brother, Drew flexing and getting off on himself at his bedroom mirror filled his head and his throbbing erection spas-med into long streams of cum that he watched as they threw themselves across his bedroom. Matt quickly ran into his bathroom in attempt to prevent his fantasy induced orgasm from getting all over his bedroom as his dick continued erupting and convulse at the thought of how hugely muscled and unbelievably erotic his best friend and brother were now.

Matt simply couldn’t wait to get his hands on some of that Flexadrinazine and at that – his erotic thoughts of the two giant muscle teens then turned towards plans on how he might possibly get his hands on some of those muscle growing capsules that lay in wait for him, in the Whitley house.




End of Part 12

Really, really liked this chapter! Cool to see Drew and their father become incredibly aroused by Chad's pheromones, what a hot scene it would be to have them so aroused by Chad that they would worship his awesome muscles and cock at the same time! Really good stuff, I can't wait for more!

[Kit Werecat]

Admittedly, I didn't see this scene coming. Excellent writing!

The good old saying, "Make love, not war" seems to be becoming a fundamental truth, overriding any hostility everybody had against each other. What a neat idea! The others may get so overwhelmed by Chad's intoxicating essence, that all the problems that would have occurred having two young muscle giants suddenly appear.. simply goes away.

Chad is becoming so irresistibly attractive as a superbeing, he's beginning to indirectly and unintentionally have total control over the emotions of others around him. He certainly is having that affect on me!!

I should have picked up on this earlier. Matt was completely overwhelmed from the beginning. I just chalked it up to raging hormones, and the thought that his Best Bud had suddenly become a huge Muscle God. But now it is overwhelming Drew, and even his Father. That lucky, lucky Father...

It's obvious that something is going to happen with Matt. I can see several ways where he can get access to the pills in that upcoming postal delivery. Then there will be THREE young teen Muscle Monsters filling the house with their pheromones! That lucky, lucky, lucky Father.

Again, PLEASE let us know how big they're getting, especially Chad, which you are still tantalizingly keeping from us. I'm beginning to have the same problem that Matt and Chad's dad now have, and I don't see relief in sight until Chad is revealed to us in all his mighty splendor.

FYI, again not a criticism or anything, but you put Chad's name in for Drew's throughout the entire first half of this chapter. I know you care about that sort of thing, so I bring it up out of respect, not to criticize. You should be proud as a writer, for you have several volunteering proofreaders at your disposal, just because they love your work so much, they are literally hanging onto every word you type.

Looking forward so much to finally get a real good look at Chad.

Congratulations again on a fine piece of writing.
