Almost five minutes passed after Seth bumped into that group of male bodybuilders when he began to sweat a lot, because he was walking with his family, he was already sweating a little, so he didn't care too much about it. However, as time continues he feels himself growing more and more moist. The medallion uses to change the user into the last person they're in contact, but Seth had made contact with at least a dozen of men, so the medallion wouldn't work as usual. Instead, it was holding all the similar features from those men and inserting that into Seth's own self.
Daphne watched from behind Seth’s situation. She noticed as her brother was twidgeting a little, like he was suddenly getting very uncomfortable. She thought he was getting tired, so she didn't pay any more attention to him. Unfortunately, that means she didn't notice that his shirt getting tighter. Seth’s chest began to push out and form small developing pecs. His nipples could be seen pushing through his tight tank top also. “Ugh, I need to get home soon.. I don't feel too well..” Seth muttered to himself as he accelerated on his walking.
Once in their home, Seth ran as fast as he could to the bathroom he shared with his sister. He closed the door and sat on the toilet for a second, that's when he realized that he didn't need to pee or poop. Instead, he only stood up in front of the sink and looked at himself in the mirror. He was so sweaty, much more than any other occasion. Seth lifted up his arms and saw his armpits drenched in sweat, however what really got his attention was that there were a lot more hairs than usual.
At the same time, Seth’s biceps began to swell causing his arms to feel heavy and making him to flex almost unwittingly. “What the heck? What’s going on?” Seth said noticing that his voice was getting deeper. Immediately after, Seth heard his bones beginning to creak and crack. He looked down at his body and noticed that he was growing taller. “Ah!! A growth spurt? This can't be a simple growth spurt.” Seth said to himself trying to rationalize what was happening to his body. He was well over 5’6” now.
Once his growth had paused for a bit, he felt intense pain coming from within his sneakers. “Shit! When did these shoes get so tight?” Seth proceeded to kneel down to take them off but was interrupted by a surge of energy jolting into his feet. “Ugh!!” He groaned while his feet busted through his size 9 sneakers revealing very large size 16 feet. “What the fu-?!” Before Seth could finish the energy jolted throughout the rest of his body causing his legs to bust through his running shorts and body to rip through his tight tank top.
“Whoa!” Seth was overwhelmed by the sight of his huge 6’8” body now. He flexed his arms again noticing how thick his biceps had developed. He looked down at his legs, they looked so thick and hairy now that matched his new manly feet perfectly. Seth looked down at his dick and balls inside his boxer briefs, and wondered if they won't grow like the rest of him. But soon after, he felt an intense sexual pleasure and he kneel down. “OOOOHH!! SHIT! IT'S HAPPENING!” Seth groaned in a deep bass while he listened as his dick and balls ripped through his tight underwear.
Seth began to moan like crazy as his balls dropped and swelled revealing golf sized balls hanging in a very loose and hairy scrotum underneath his shredded tight underwear. Seth began to intensely stroke his cock as it thickened and lengthened. He was getting a proper set to match his bigger frame. He groaned and moaned in his new matured voice. He didn’t know why he was feeling so much pleasure or why he can't stop but his body was moving almost instinctively.
As he kept stroking, Seth felt a deep pressure building inside of him. He continued to moan louder and louder until he suddenly released a huge stream of cum all over his chest, floor and mirror. “Ugh, that’s intense...” Seth panted while he took seat on the toilet. His butt was so large, that he didn't feel too comfortable at first but he stayed there anyway. His hard cock was getting softer and he felt even more uncomfortable when his glans touched the water inside. A few seconds after he came, he heard his mother asking for him, he felt so exhausted that he didn't think how his mother would react when she watches him. He stumbled onto his large feet and began to walk to the door.
At first, he didn't look at himself in the mirror, so he didn't know he now looked like a 30 year old hirsute bodybuilder version of himself. But when he took another look, he realized it and freaked out, almost falling to the floor. He managed to hold the sink, but he made a loud thud anyway. Seth didn't know what happened, he wasn't sure if he wasn't dreaming, but he was determined to don't hide this from his family. How would they take it will be something interesting to know.
