Josh and Jake froze hearing Jake's mom's voice outside the door. They moved out of the stall into the main bathroom.
"Jake you've had to pee a lot. I'm worried you're sick."
"It's nothing, mom!" Jake cried. His cock was still hard enough that he was unable to fit it into his little shorts, hanging at a semi hard 16 inches and as thick as a can. Josh desperately tried to ring his jeans around his shoes.
"I'm still worried sweetie. I'm coming in!" Neither of them would be able to get their pants up in time.
"Pretend you're peeing!" Josh hissed, he and Jake darted to the urinals and Jake began to shake his cock off like he was finishing peeing just as the door swung open.
"Ja-Oh!" She gasped as the door opened and the urinals came in her full view. She looked straight past Josh's insignificant penis at her son's massive eel flopping around in his tiny hands, her eyes nearly bursting from her skull. "My lord!"
Jake said "Sorry mom, my wiener can't fit into my shorts."
"Jake, sweetie, she knelt down beside him with her eyes locked on his swaying cock. "This all makes sense now. You should've told me that you started puberty honey. We need to talk about things like this. It's all the more important now that you have a huge cock. It has probably been swinging into things and brushing high objects as you walk and now you've gotten a urinary tract infection." she hoisted it up by the base to examine his glans, but underestimated how long and heavy it was and the remaining s13 inches that poked out of her hand drooped. So she grasped the upper half of his shaft with her other hand and lifted it up with both and stared at the glans closely like she was using a big spyglass "You have to clean it more often and wear briefs so it can't swing all around like that. Having a penis as big as this is a great responsibility, it's how a man learns to take care of himself and survive. It's much more work than..." and her eyes fell upon Josh's little, undetailed nub, as well as his pants around his ankles.
"Excuse me" she said "but why are your pants all the way down?"
"Well" Josh stammered "I can't be sure that I won't pee on my pants unless I pull them all the way down."
"Oh, I see" her expression was half pity half hilarity "because it's so small. See honey, his little penis isn't as troublesome as yours because it pretty much stays by his body like a nipple, so he can't get infected by it touching things he sits on or walks by."
"I understand mom" Jake said "maybe when you and Dad help me get dressed and do my hair in the morning and at night we can take some time to clean off my penis too! Just to help me remember"
"Good idea sweetie." she said, and she took a sanitary wipe out of her purse and rubbed it along his enormous glans, like she was polishing a red delicious apple. She even took some time at the end to tap the precum off the end, accidentally leaving a long, silk strand trail. "But it should probably just be me that cleans it, we wouldn't want your father to get jealous." Josh's little penis unintentionally grew erect at this, and Jake's mother somehow noticed.
