After Jayden’s cock had sprayed his seed all over Isaac, the preteen ran out of the classroom, leaving Jayden behind. Luckily for him, Isaac and his older brother lived in a small house only three doors down the street from the school, so he knew that he could get home very quickly.
“Awww yuck! This is disgusting!” Isaac groaned, as he tried to wipe all the sticky, white cum from his face, arms and chest. But it was already too late. The boy already became infected and he started to feel his own cock as it began to throb in his groin, just as he made it through the front door of his house.
Isaac ran into the house, removed his clothes and jumped in the shower, making his 15-year-old teen brother Miles wonder why his younger bro was in such a hurry. Miles got in the shower and washed everything off. When he came out and dried off, he ran into his room. He was about to get dressed when he was about to experience an incredible orgasm as his cock grew from a small 4 inches to a whopping 8 inches in length!
“UHHHHHHHH!!!” Isaac groaned loudly, laying flat on his bed as his cock grew while his balls inflated to the size of softballs. A long torrent of cum followed, which Miles heard in the room next door.
“Isaac? What’s going on, bro? What are you doing in there?” Miles said as he knocked on his brother’s bedroom door.
Miles had just turned 15 and he was at the very start of puberty. He was just 5-foot-8 inches tall and skinny as a board. But he was dealing with an outbreak of acne and all the other things that teens had to deal with at the onset of puberty.
Miles became concerned and opened the door, just to find Isaac on the bed with a huge monster cock sticking out from his groin!
“Dude! How did your dick get so big?” Miles asked, as he walked up to the bed and bent down so he could examine his little brother’s cock. Just as he was about to touch it, a big, hard, thick stream of cum shot from Isaac’s cock, dousing Miles in his cum!
SPLOOSH!!!
“ACK! ISAAC! What the hell, bro??” Miles screamed.
“UHHHH! I can’t help it! ARRHHH!” Isaac groaned as he began to orgasm again.
Just as Miles stood up, he was overcome by a weird, tingling sensation. He turned around and walked out of the bedroom and headed to the bathroom where he tried to wash off the cum from his face in the sink, when his own 5-inch cock began to tingle like crazy.
Together with his own puberty and his already heightened testosterone, Isaac’s cum bath suddenly caused Miles’ own testosterone level to skyrocket! His skin began to itch all over, and hair began to sprout everywhere. Miles felt a sharp burning sensation in his muscles all over his body, like he had just come from a long, intense grueling workout in the high school gym. His legs were aching all over, like he was about to experience a massive growth spurt! His cock suddenly grew to 9 inches in length and 2 inches in girth with testicles as large as baseballs, and he became as aroused as ever!
As Miles removed his clothes and plopped down with his back flat on his bed, he could only look down in shock at his BIG cock, which had grown into a foot-long monster. Thick white drops of cum began to leak from his cock tip as his body started to change and grow in every direction!
