Nothing he knows about.

He had been almost late this morning and the t-shirt had been the only thing he could find in his room. He had put it and a pair of socks on and went down school bag in hand, hoping to find something in the laundry room. But his mom was in the way handing his shoes and berating him for his tardiness, she had almost pushed him out of the house before he could say a word, telling him that if he missed the bus he'd have to walk to school. He wanted to argue but the bus was already visible at the end of the street and he barely had time to reach the stop before it.

Miraculously he had managed to last this long unnoticed, due to a lack of uncontrollable erections that he was prone to and that would have made a ten inch long schlong impossible to hide. But right now he was out of options. As hard as it was he had decided to confront his teacher about it rather than to look like someone who would just strip naked in public like that.

"Mr Smith, I thought that even someone like you would have understood such a simple assignment. Go remove your t-shirt and your shorts and put them on your desk." she told him when he went to talk to them. A good half of the classroom had already left and the rest, mostly girls were more busy folding their clothes neatly than stripping of their extra layers of clothes.

"Please Mrs Winslow, I don't know what to do. There was an unfortunate incident when I left this morning because I was almost late and this t-shirt is the only thing that I'm wearing." he whispered to her. He could see her go red, but it was more due to anger than embarrassment. He knew that she was an absolute stickler to the rules, having once given an F to someone for finishing to answer one sentence on a test after she told everyone to stop writing. There would be no way to convince her to help him, but it was his only shot.

"Young man, your depraved sense of fashion is not my responsibility. I will not let you get the rest of the class get in trouble due to tardiness. I hope this will teach you a lesson." she said before grabbing the bottom of his t-shirt and pulling it off over his head. " I'm confiscating this, you'll get it back in the principals office to discuss your disrespect of the school's dress code, once we're done with this."

K-T barely had time to reach down to cover his crotch as girls laughter erupted behind him and Mrs Winslow locked his t-shirt in the drawer of her desk.

K-T was blushing from being so exposed and as often in such situations his dick started to harden. Mrs Winslow had to hurry up the girls who were now too busy laughing to continue stripping. What K-T didn't know was that his nakedness was only part of what made them laugh.

His sister Emily had a sleepover with some of her friends last night and he went to sleep early to avoid trouble. Unfortunately he was a heavy sleeper and after a trantum of his mom who had caught him jerking off one too many times, his dad had removed his bedroom door. In the middle of the night, a gaggle of giggling girls, knowing his habit of sleeping naked and the fact that he was a heavy sleeper had visited him for some pranking. Disappointed of finding him sleeping on his belly with his long cock hidden under his legs, they nonetheless had some fun. A pair of permanent markers and half an hour later his entire back and butt was decorated. It looked in style like the back of a biker jacket, with intricate symbols all made of dicks and balls as well as some inscriptions like DICKS FOR LIFE, BORN TO CUM on his back and sadly INSERT HERE above the ten dicks drawn on his butt, all pointing to his asshole.

They had limited themselves to his back hoping he wouldn't notice it before having to change for PE the next day. And their plan had worked a little too much since it wouldn't be just a dozen boys in a locker room who would see it, yet K-T himself was still unaware of it.

The hallway was full of movement, but because of the delay he had created they were the last ones to arrive and since he was at the back of the line, the other classes hadn't noticed his state yet. They lined up on their pre assigned lane and waited for the officials, currently busy talking with Mrs Valence the principal, to explain what it is about.
