Ethan couldn't believe how big he was, his muscles rippled under his tanned skin. Wearing just a pink speedo he found, The teen went to the beach, looking for his friends.
Then he saw Liam, Chris and Zane. They walked up to him and greeted him like normal, with a kiss on the lips. He was shocked, what was happening? "Notice anything different about me?" He asked, wondering if this was all some kind of prank.
"New speedo?" Zane asked, "I like it."
Ethan found himself taking it off and handing it to Zane. "It's yours then."
Suddenly, Ethan felt even heavier. He saw his chest expanding even more, shoulders too. His whole body was expanding right before his eyes - right in front of his friends. His arms got huge. Chest and belly too... but he wasn't getting more muscular. Much to his horror he was getting softer, fatter, and soon he was a big fat chub standing naked on the beach. "Whoa, what happened?" he asked, not understanding anything about today at all.
"What do you mean?" Liam asked.
"I'm huge - I must be a 600 pound chub!" Ethan answered.
"650, remember?" Chris answered. "We've been telling you for years you need to stop eating like a pig and start exercising more - it's amazing you can still walk!"
"Oink!" Ethan said loudly. He made more pig noises and his friends rubbed his belly, calming their morbidly obese friend down.
"It's okay," Chris said. "You're fine. You can always hang with us.... we're okay that you're a fat piggy boy, nobody gives better blow-jobs than you."
With that, Ethan dropped to his knees and rubbed his face in Liam's crotch, enjoying the feel of the boy's hardening cock and eager to take it in his grunting mouth. A few seconds later, Liam inserted his hard member into his fat piggy friend's mouth, and Ethan got to work sucking the cum out of him right there on the beach.
People around them watched, and started chanting, "Piggy, piggy, piggy, piggy!"
After sucking each one of his friends dry - the cum adding more fat to his already obese body, he just sat on his fat ass on the beach playing with his nipples, grunting and drooling. Whatever he had for muscles beneath the fat had faded while he was servicing his friend, because his whole fat boddy was sagging even more than before, all the muscle tone that held his fat up before was gone. Now he was just a flabby, hairy naked guy on the beach, asking guys who passed him if he could suck their cocks. Some let him, others just laughed. He had a large tat across his back that said "Cum Pig" and another across his belly that said "Cum Dump". He wasn't very bright any more. This would be his new life from now on.
