Waking up Steve felt great, after the explosion he sort of dozed off. He wanted to stretch but his arms were plastered to his side. He squirmed. The sheet was coarser than he remembered, Steve struggled to stand to get his head out from under the covers. His feet seemed rooted under great weight. Perhaps the mattress was on top of them. He'd just had one hell of a wet dream. He could feel and taste the cum drying on his face.
Steve suddenly saw light as the cloth covering was lifted back. He looked up into little brother Bobby's eyes. Man this was wrong. He was looking straight up passed his belly button and bare chest up into his mean grinning face. Steve glanced down at his own wrinkled tubular body, he felt like his knees were bent into his chest, but all he saw was a giant penis body. It hadn't been a dream! Or maybe he was still sleeping.
"We're going to take a piss, but the space between the toilet and the wall is only about three feet. So as much as I hate to do this Stevie boy, I'm going to have to make you a more manageable size," Bobby said regretfully, adding with a bigger grin, "Except when I'm hard!"
Steve gasped as Bobby started to grow, and he realized he was shrinking. He struggled back and forth against the rough fabric.
Easy Steve-o, the jockstrap seemed to say to him, you'll just make him cum again, and that's where the magic is cumming from.
A face seemed to form in the fabric, it looked like Bobby's best friend Erick. Oh, shit, thought Steve, if he turned Erick into underwear, there's no hope.
"Right oh, Steve-O! Haha!" laughed Bobby, "In case you haven't realized it, you and Erick, and Ryan and Carter are all telepathically linked to me. I can read your mind, and I know you secretly are enjoying your new place in the world."
Steve was horrified, but before he could speak or think anything, he fell forward staring into the cold white watery bowl of a giant toilet. A hot salty torrent filled his body and exploded in a hard stream out of his mouth.
