Harry glances back into the hallway. The shower was still running and Harry heard a couple grunts and moans. Matt was still occupied, at least for now. He quickly went back into Matt's room and began eagerly looking around.
He spied a white shirt, clearly well worn and dirty, on the floor. He picked it up and spied that the shirt was off white/yellow under the arms. He closed his eyes and took a deep sniff of the armpit. "Oh fuck....", he moaned, "this is so fucked up". The shirt reeked of Matt's BO. Harry kept sniffing and his cock rapidly swelled in his pants. Within seconds, he was painfully hard in his jeans. Harry wondered how much sweat Matt deposited in the shirt, how much Matt's smelly, hairy armpits had made the shirt stink. These thoughts were make Harry so turned on, not to mention the thick heavy musk from his brother.
Harry took his nose away from the shirt for just a second, enough time to turn the shirt inside out. He put his nose against the fabric and got an even stronger blast of smell. He noticed his nose tickled by what he assumed was a long brown pit hair, which must have fallen off of his brothers hairy armpit while he wore the shirt. Damn, Matt stunk! Harry knew he should be disgusted and he wanted to stop, but he knew that be couldn't. If his raging boner and rapidly spreading precum stain in his pants were any indication, he was enjoying himself too much. As he kept sniffing, he Absent-mindedly scratched his own armpit. Ugh why was it so itchy?
Harry dropped the shirt and began to search around the room. He spied a dirty sock on the floor, which he eagerly picked up. To his horror, and simultaneously, delight, he noticed the sock was crusty and stiff! "Oh fuck, it's a cum sock!", he said to himself, as he touched the filthy sock.
Harry stuck his nose into is and greedily sniffed. His cock was hard as a steel pipe. As be sniffed, he reached down and rubbed his bulge. He briefly thought to himself that it was bigger, before the smell ceased all thoughts in his brain. He quickly turned the sock inside out and frantically began to lick the old load. Harry was disappointed, the load had completely dried and there wasn't much flavor. The rancid foot sweat, however, made up for it. Fuck, why was Matt's mansmells to irresistible to him now! He shoved the sock to his face, breathing out of it like a scuba regulator, as he kept looking around Matt's room for more musky treasures.
His eyes meet the trash can full of spent tissues, and Harry's heart starts to race. He drops the cum sock and drops down, and begins to sift through the trash. Bingo! Within seconds, he found a wet tissue that just reeked of the fresh stuff. Harry peeled the wet tissue apart and almost came in his pants right than and there; the wad of tissue was full of one of the biggest loads he had ever seen, and it looked brand new and fresh too! It looked like a horse had made this load, he thought to himself, amazed that this sheer volume of cum had come from his brother's balls! He leaned in even closer and took a deep sniff, oh god it smelled heavenly! He began to lick the salty load his brother had left behind, savoring the flavors. It was the best thing he had every tasted. Totally lost in the experience, Harry failed to notice his cock, already hard as a steel pipe, was stretching out even further and further! Totally unbeknowst to Harry, all of the musk sniffing and cum eating changing him! His cock had grown about a full inch longer, and, judging by the tightness in his jeans, his balls had likewise dropped a bit further and expanded. Harry kept licking and sniffing as thicker and longer pubic hairs squirmed their way out of his groin and balls. Still totally focused on the dirty cum tissues, Harry absent-mindedly scratched under his arm to relieve a terrible itching sensation. If he was paying attention, he would have noticed his armpits had much more hair in them than before he stepped foot into his brother's room. Harry would find out later, to his dismay, that his pits had started to produce a thick, strong BO from now on, much like his brothers musk.
As Harry kept sniffing the tissues, his eyes wandered until he found a dirty, obviously well worn pair of boxers on the floor. Picking it up eagerly, he turned it inside out and began smelling the crotch area. The pouch was hugely worn and stretched out; Jeez, his brother must have a huge package. He took a deep sniff of the rancid ball odor and moaned out loud, his stiff member dripping even more precum. To his delight, there were a few stray long brown pubes in the pouch, which Harry eagerly stuck in his mouth. He licked and sniffed the rank sweat and stink and cum stains off the boxers when he heard a sound behind him that made his blood turn to ice.
"What in the fuck are you doing".
Harry turned around wide eyed, the dirty boxers still held to his face, as he came face to face with Matt, dripping wet from the shower with a towel around his waist.....
