Be Andreas's underwear

While Andreas stood bent over his gym bag struggling to get his phone into a pocket, Linus elongated his arm and slithered it into Andreas's bag. He then felt around for Andreas's boxer briefs. He looked around a bit and eventually found them. He then took them out, slowly retracting his arm with Andreas's underwear in his hand. They were just cleaned according to the smell. Linus then threw them away and dropped his whole body into a puddle on the floor. Linus then floated over to Andreas's bag and got in to where he had found his briefs. He then collected himself into a flat sheet of elastic fabric. He made three holes in himself, two for the legs and one for the torso. He made himself completely white. He then started to wait for Andreas to start moving.

"This fucking zipper won't fucking work!! Ugh, fuck it, I'll just hold the phone." Andreas said after 3 minutes of franticly trying to get his large phone into a too small pocket.

"Hey, thank you for your num..." Andreas started to say while standing up and turning around to face Linus, but to his surprise, Linus was gone without so much as a sound.

"Hmm, weird. I'll ask him how he could be that quiet tonight." Andreas muttered to himself while he packed up his bag and headed to the rest of the boys.

Andreas was already dressed for gymnastics so he just placed his bag on the benches along the wall and joined the training, leaving Linus in his bag to wait.

An hour or so later, Linus could feel the bag moving again and hearing boys chanting - the training was over. The boys then headed to the showers to freshen-up after a nice session. Once in the locker-room, Andreas opened the bag and took out his towel. This made Linus slide down the side of the towel when it was being picked up, landing on the bottom of the bag and having the rest of Andreas's clothes land on him. Andreas then undressed and put all of his dirty clothes in a plastic bag in the bag, filling the entire bag with Andreas's musk. Linus got extremely turned on but knew that he had to play underwear to avoid being discovered. Andreas then went to shower, followed by the rest of the team.

"Hey Andreas! Nice ass!" Shouted one of the members of the team. It wasn't an insult, it is something all boys in the team says to Andreas since his volleyball sized cheeks easily triumphs all of the other boys asses.

"Kiss it." He responded and started twerking against one of the benches to whistles and towel smacks from other boys. They all laughed.

"No but seriously, great work today guys! I'm sure we'll win the championship next month if we keep it up like this." Andreas said to applauses from the rest of the team.

"Well, it's all thanks to our amazing leader with an equally as amazing butt." Said Chris, the most forward one in the team.

"So, he's even the leader of the team." Thought Linus who just found it even sexier.

"No no, I can't take credit for your work, seriously." While saying this Andreas began to put on his underwear. He didn't even notice that they were the wrong kind of fabric, size and even color.

Linus felt himself getting picked upped by Andreas's incredibly strong, yet delicate hand which felt so good on Linus's skin. He then lowered Linus and put his feet through the smaller holes and began sliding Linus up his legs. This felt so extremely good to Linus, who had to concentrate so hard not to get erect or moan from the intense feeling of having someone's legs slide through you. Linus then got all the way up and made sure to snug tightly around both Andreas's package as well as his butt. What Linus felt was indescribable.

"Hey, boss. Those briefs look really good on you, where'd you get 'em?" A boy from the team asked Andreas.

"Huh?" Andreas then looked down and realized his new briefs and his the really accentuated his package, without feeling uncomfortable.

Andreas lowered a hand to rub the briefs and Linus almost came from the sensation. Andreas just looked down at them and couldn't remember where he had gotten them or why he'd even buy this type of briefs to begin with.

"I dunno." Andreas replies. "I don't remember ever even seeing these before."

"Still!" The guy says while closing his bag and puts it over his shoulder preparing to leave. "Makes you look like a magazine athlete. Take care!"

"Yeah...you too." Andreas just stood and looked at them trying to grip the fact that they were there on him.

Linus had definitely disguised himself well, he looked like a real pair of elastic briefs that even got Andreas compliments from the other boys. It was so good that Andreas stood for almost 30 minutes before accepting reality. By then everybody from the team had left and Andreas was alone in the locker-room. Andreas looked at the clock, it was 16:30, he was gonna be at his date's house soon, he better get going.
