Rob the janitor comes through doing his job. Cleaning, picking up the mess and his favorite thing was to go through the dirty clothes and pick out a nice used jock strap, uniform or maybe a speedo or two.
Rob wasn't having any luck when he got to the speedos and most were average but when he got to Chad he saw that it was one of the larger ones. Chad had been made to be worn by the coach but he was still quite stretchy.
Rob took this speedo stuck it in his pocket and after he got done with his duties and headed home. When he got home he had dinner. Sat and watched some stupid television show and got ready for bed.
As he undressed he stuck his hand in his pocket and found the speedo. Not thinking about it he lifted it up and sniffed it. He loved the smell of a man on their cloths and inhaled the aroma left in the Chad speedo.
Chad began to wonder what this new sensation was. Someone was breathing in all that dried cum that was embedded in the fabric that was the speedo,
Rob loved the smell. As he lay on his bed rubbing the speedo on his balls and dick he eventually came and then was going to toss it to the side for the morning. But something told him to try on the speedo and he got up and tugged them on. They were quite different than when the coach wore Chad. He felt every fiber of himself pulled to the max and they rose up and around Big Rob's middle.
Having looked at the speedo when he took them out of the bin he had thought they would have never fit him but here he was with this speedo pulled up around his rotund middle. Rob was quite a bit bigger than the coach. Chad had thought Coach was an overweight middle aged man but Rob was an obese boy. No where near middle aged. He was in his early twenties but easily twice as big round as the coach was. And a good foot shorter than the coach was. Somewhere near 5'4" tall and about 400 to 450.
Chad couldn't figure out how this boy was wearing him and not tearing him to pieces but as he settled in place Big Rob laid down on the bed and began to fondle himself again and came again onto the Chad speedo and soon was fast asleep.
When Rob woke in the morning the speedo seemed to fit him much easier. Where the night before the speedo felt quite tight now this morning it felt almost loose. He went in and had his breakfast and headed to the shower taking Chad off. As Rob got out of the shower he was dressing and going to put on some nice tighty whities but he got the idea to put the speedo on and he put on his coveralls and headed to work.
Now the coach didn't know that Rob had stolen the Chad speedo and Chad was only able to communicate with the coach but as Rob came in to clean the locker room the coach knew immediately that Rob was wearing Chad. He started to almost giggle at the thought. And then he had a wonderfully devious idea. He called Rob into his office and started to show him a few things around the office that he wanted cleaned. At some dust in the corner Rob couldn't see it. The coach told him to bed down and take a look. Coach took that moment to put his hand on Rob's back right at the exposed speedo making contact with Chad and in that instant the coach told Chad that if he was a good boy he might change him back into himself in a year or so if he treated Rob right.
Now Rob didn't realize what the coach was doing and being gay Rob was enjoying the touch of another man. Something that he was missing so much. Chad didn't want to spend a year as this fat man's speedo but if it was a chance at being human again he was going to do all he could to please Rob. Chad agreed with the coach's proposition and off he and Rob went.
Now there isn't much that a speedo can do to please someone but he was able to manipulate the fibers of himself which massaged Rob's groin and made him feel as though he was with a man every time he wore Rob wore the speedo.
As the year wore on Chad became adept at massaging Rob and making him really enjoy being worn.
As the year passed and Rob was once again called into the coach's office Rob was once again touched by the coach and at that point the decision was made about changing Chad back.
