Samu's mischeif

It was a lone after the school day, Samu was walking down the halls hand sliding against the lockers as he walked past eyes glossed over in slight boredom till he saw an individual walking ahead of him. “Felix??”, Samu muttered in a whispered tone watching the other teen walking towards a lone classroom before heading inside. Samu smiles mischievously as he begins to slowly follow behind. “Guess today won’t be so boring after all…”, he muses to himself. Samu slowly peaks into the room, revealing it to be a science lab with many concoctions bubbling on the burners and mixing in the tubes. A curious thing and it might be a little science experiment perfect for some trouble making. He looks to and fro between each tube pondering which to mess with first. He finds himself in front of two tubes that tickle his fancy one small and one large.

Samu begins reaching for the large one to take and causes the most damage when a voice announces from the back: “Philip I did it, I perfected the muscle growth serum!” A familiar voice none other than Felix’s in fact. “With many tests I got it to the point that it’s safe to drink, so come on let’s test it out!”, Felix follows up sounding giddy. “Wait what!? What do you mean you’re in the middle of a card game?… do you want free muscle results or not?… then come back to school, I will be in the science lab on the first floor… alright see you soon.”Samu can see the outline of Felix’s shadow move and the sounds of his footsteps approaching the doorway. Samu panics with a whispered shy realization he had less time to mess around than intended but that news about what felix was working on sounded too good to be true, he had to take one. The steps getting louder Samu panics and grabs the one closest to his hand, unfortunately it was the small vial and makes his way out the room and down the hallway.

After a bit of running Samu manages to make it to the locker room a bit down the way. He peeks out the door to check and see just in case if he’s been followed before pulling it back into the room. “So this is some growth serum huh?”, Samuel questions as he examines the contents that swirl within the small vile. He takes in a deep breath: ”let’s see what you can do then.”, he says as he drinks it down with a gulp and wipes his mouth before feeling a ticking and surge of strange feelings. His breathing becomes faster as he takes off his shirt and tosses it to the side and before his eyes comes the miracle of the serum.

He can begin to see the contours of his thin frame change, as his small bicep wiggles and grows before his eyes. Rounding out to like tennis balls of raw muscle and hardness. He looks down and sees his chest pushing forward as a small shelf like set of pecs forms. Reaching out to give the newfound muscle a grope and finding it’s all too real and hard too already with enough firmness to keep even his own hand away but not too big just yet. Soon his hands slide down feeling the rows upon rows of abs that pop into his stomach and count a glorious 6 divided rivers of muscles. Samu chuckles in joy. As he slid off his shorts and watched his hard on grow, twitching in his boxer breifs and already leaking pre cum in them making a light wet spot. Further below he sees the definition of his legs grow as they thicken with strength and calves just below rounding out and shaping strongly.

Samu stood in the locker room, heart palpitating with joy and euphoria. He takes a finger rubbing the tip of his hard cock in his boxers, enjoying the tantalizing feeling. He lets out a light moan and a gasp as he continues to play with the head of his dick before sliding his hand down for a few strokes.
Lips pursed in delight as he enjoys it for a good moment pumping himself and playing with the sensitive dick head. He soons pauses as his mind races with new prospects. This was just a little sip and he’s pretty fit right now. If he took the big jug back at the lab, how much stronger could he have gotten, he wondered. “Actually…. I don’t have to wonder… I can just take it” Samu says with an eager smile. Strutting off powerfully leaving his clothes behind cause why would he bother to hide his newfound body.
Back at the lab, Philip and Felix are chatting away. “…so you can’t find the tester batch?”, Philip asks, holding the jug filled with alot of the serum. “Yeah it’s kinda weird maybe I misplaced it or something… I don’t know… but…”, Felix turns to philip, arms over his shoulders: ”…you’ll be the test subject for this batch and if all goes well I can make more!”, Felix says giving philip a wink. That is until the door has been opened and they see with surprise.

”Samu!!???”, the two teens say in unison with both confusion and surprise seeing his muscular build before them as he waltzes up towards them too. And no sooner than he walked up to them snatches the jug outta Philips hand. Philip looks at his hand in surprise and tries to interject and stand up for the theft but samu simply says: “Hehe, you should’ve been faster to be a test subject!”, and downing the contents.

Before the two teens they watched as Samu began to bulk up right before them. His pecs push forward as he flexes them with a smile being like deep shelves of muscle pushing off like a good few inches off his chest now. Biceps like rounding out like round soft balls, his abs diviting and shaping from a good 6 pack to an 8 then from a deep cresting 10. Samu slides his finger into the crevices feeling the creases and giving the other two boys a smile. Samu flexes his legs as they bulge and refine, with strong formations of muscles wrapping around them and below his calves shaping like strong footballs. He look like an athlete merging into bodybuilder territory as he brings both of his arms up and flexes his biceps and making those muscles peak like little mountains. Samu turns to the two other teens before him, smiling at them as he was more muscular but not taller but it was still all the more enticing.

Philip and Felix let out a relative gasp between each other as they walked closer to Samu’s glorious newfound body. Hands exploring their muscles, hands feeling up and squeezing his hard pecs. Felix explored each ab with his hands not realizing how close he was to Samu’s cock that grew bigger too and slipped out of his underwear. Throbbing out in the open and leaking a few drops of pre on the floor as he finds the two boys exploring his body, deeply arousing.
Philip’s hand squeezes Samu’s bicep with both some awe and jealousy and he sees the smaller teen turn to him with a ‘you wish you got this huh’-look plastered on his face. Philip attempts to squeeze Samu’s softball like bicep but to no avail the muscle doesn’t budge. Felix explores one of Samu’s pecs feeling the plum shape of them and enjoying their firmness. Samu gasps a bit as he finds a surge of pleasure from a brushed by nipple following Felix’s arousing touching session. Soon they explore lower Philip see’s that massive cock, as long as a forearm throbbing before him and his jealousy rises onces more as he touches it. Feeling its warmth and thickness, Samu moaned again from the joyful pleasure their touches brought to him as Philip touched it some more. Ending up getting a bit of pre on his hand as samu’s cock gives Philip a light parting gift.
Felix explores Samu’s legs as he feels the definition worthy of a track star, each ripple almost intoxicating beyond belief as his finger found ridges he never knew could be there on Samu’s sculpted shape.

Felix finally retracts his hand having his fill before speaking up once more: ”Ahh… I’m thankful to have you as a… test subject and… getting hands on with the fruits of my labor is quite… beneficial.“, he says adjusting his glasses. Samu smiles looking at Philip who honestly felt left out. “But I would advise you to stick around so we can see the full range of the… side effects…“, Felix follows up.
“You mean they’re side effects!!??”, Samu exclaims fearful of what could happen.
“No!… It’s what’s going to happen to you if you run off and don’t continue to be my test subject!”, Felix follows up sending a cold shiver down both of the other two boys’ spines.
