Kyle wasn't used to having a 15 inch tool yet, and with his mother mere moments from entering his room, he had no time to hide it. Making a snap decision he decided to whisper "I want to be in the bathroom." Immediately he was transported into his bathroom in a seated position on the toilet. It took his brain a moment to adjust to him instantly being in another room with zero transition. From down the hall he heard his mother opening his bedroom door and calling his name. She must have assumed he was in the bathroom as immediately afterwards she started walking to the bathroom. With another quick wish the door was locked and she had now way in.
"Kyle are you in there?" She asked, muffled through the door.
"Um, yeah."
"Alright, well I made us brunch, so come downstairs when you're done." She said, quickly walking away. With a moment now to breathe, he realized just how close he came to his mother seeing him half naked with equipment that she might suspect he didn't have just a few minutes ago. Looking down he noticed that his dick, despite being completely flaccid was still 15 inches. He supposed that he just hadn't noticed it getting bigger when erect before. Kyle decided to get up from the toilet and try his hardest to hide his 15 inch long schlong. This was highly unsuccessful, as his boxers and sweatpants just weren't properly equipped to deal with a package this large, and neither were most undergarments. Not wanting to wear a cock sock anytime soon, Kyle decided it best to decrease his size, at least for now.
"I want to have a 10 inch long penis." Instantly his cock started shrinking down inside himself. Going back up felt almost as pleasurable as coming out, and if it weren't for the fact that his dick was shrinking right now, he'd probably have been as hard as a pole. After his endowment had reached a smaller but still large length of 10 inches, (still bigger than before), he was able to stuff it inside his pants. If you stared too long at his crotch you'd definitely know something was wrong, but he wasn't worried about his mom noticing it.
Walking downstairs he noticed the foreign feeling it had with the new weight in his front, which he hoped wouldn't throw him off balance. Walking into the kitchen he smelled the pancakes his mom had made and immediately realized how hungry he was. He sat down at the table and began eating.
After just a few minutes Kyle had finished eating, but not having had much to eat today yet, he was still somewhat hungry. This was when he made his first minor mistake. "I kinda wanna eat some more." He said offhandedly. Suddenly, his plate was completely full again, and he was panicking. Had his mom noticed? He looked up at her to gauge her reaction, and she said nothing. She just kept looking at her plate. She than responded with "Than eat some more if you can." Had she not noticed? Or was she incapable of noticing. It's something he hadn't considered before, but it was possible that she couldn't notice the changes he made. He needed to test with something a little bigger.
