Liam, the 20 year old son in a five person family and at the moment he was home from college for Spring Break. Life was in a word perfect for him. He was blessed with an attractive face and a huge muscular body, not to mention a smoking hot girlfriend. At the moment he was relaxing at home watching TV. "Man, there is nothing good on right now!" he said to himself. He was quite bored at the moment. He got up as he wondered what else he could do. "If only something could happen to spice up afternoon," he thought to himself as he stretched. As he did, he felt a burning sensation in his stomach. "Ow! What the heck?!"
Liam rubbed his stomach. As he did, it felt like his abs were shifting in his hands. "What's going on?" Liam tried to stretch again, but his body started to hurt even more. "Ohh... My body..." Liam looked down and was hit with an even more bizarre sight. His shirt was starting to drape over his short more and more, almost like he was shrinking. "The fuck? Ohh... God..." Liam felt his body get hotter. "Gah!" His body shook as it got even hotter. It was like he was going through a particularly grueling workout. His dick hardened up and tented his shorts. "Jesus Christ! What's going on?!" As his body continued to change, his shorts fell off his waist and his boxers followed soon after. Now his dick was simply tenting his shirt. "Whoa! What's happening to me?!" Liam watched himself in shock as his eyes got closer and closer to the floor. His arms and leg muscles sunk into his body. "No! No fucking way!" Liam looked down his shirt and saw his pectorals got soft and flabby and his eight pack abs started to dissipate as well. "Oh god! My body! No!" As his muscles disappeared, the rest of his body started to get even smaller. It was like he was regressing in age. His dick tented his shirt less and less. "No! Stop! Ahhhh!" The changes to Liam's dick caused it to get extra sensitive. "Ah,ah,ah,ah! Wait! Nooo!" Liam couldn't help himself as he ejaculated into his shirt. A wet spot formed as leftover cum spilled onto his smaller feet. After about ten seconds, the ejaculation subsided. His dick got soft and was now no longer able to get harder ever again.
"This isn't real! This can't be happening! Ahh!" Liam lamented his fate and out of his mouth came a much younger voice. "Ahhhh!" Liam simply screamed as he continued to get smaller. Looking down once more, his shirt was practically hitting the floor. His tiny feet were just visible from the fold of clothes. He wiggled his tiny toes, trying desperately to convince himself that what was happening wasn't real. "Gah!" Liam's body shook once again as he passed the ten year old mark. One side of his shirt now hung off his body. His teeth sunk back into his gums and then back out, but they were now baby teeth. "Oh my god! I'm turning into a fucking kid!" he exclaimed, the cursing coming out as weird from his young voice. "Gah!" One more shake and Liam felt one more major shrink. Passing the five year old mark, his boy finally stopped shrinking. Unbeknownst to him, his eyes turned from green to blue and his medium cut blond hair turn a short brown. "Gah!" One more shake, and the grip on his body loosened. "Gasp! Haaaah!" Liam took a deep breath and felt the major changes his body went through hit him all at once. "Ahhh..." Liam lost control of his bladder momentarily and peed himself, staining his shirt even more. "Ahhh!" Liam yelled as he covered his tiny, hairless cock and balls to stop the peeing and after a couple of seconds, it did. "Jesus Christ!" was all he could say.
He looked towards his phone to see his new body in the selfies mode. "What?!" he yelled out. What stared back at him was a little kid and one that was intimately familiar to him. It was none other then his weak, plain looking brother Sam. "What the fuck is this?!" he yelled out. In response, he heard someone run down the stairs and into the living room. It was man, huge and muscular and very good looking. He was stark naked, his huge cock flapping up and down, but that wasn't what disturbed Liam. It was what the body looked like. "L... Liam...?" the man who looked just like his twenty year old self asked. Liam opened his mouth wide in shock. If he looked like Sam right now, then the man who looked like him now must have been... "No fucking way... Sammy?!" After a few seconds, the man answered back, "Ye... Yeah..." and confirmed who he was. "What the fuck just happened?!" Sam didn't answer back and they continued to just stare at each other. Well, Liam wanted some spice in his afternoon and he was definitely getting it.
