Coach finishes his swim workout and heads back to the take a shower.
As he does he sits on the bench and takes Chad off putting him in a dark gym bag.
Having finished his shower he heads to his office to change and head home.
Walter comes into the locker room to work out after everyone has left and finds the coach's gym bag.
Opening it up he sees the blue swim suit and pulls it out.
Chad tries to protest. He had just been worn by the coach. A big old man and here was Walter. He had been the center on the football team until he got too fat to even work out. He was easily twice as big as the coach and his ass was massive.
He pulled on the suit with great difficulty and Chad stretched to fit. But what would happen if he ever became human again?
He went in and swam for a quick workout which made him exhausted when the assistant coach yelled at him to go home.
Not having time to change he pulled his pants on over the suit and headed home.
When he got home he pulled Chad off and looked at the suit. It looked like it was easily an 80 inch waist and he wasn't shrinking down. Chad was in terror that these changes would drastically change him if he were ever to change back.
Walter enjoyed his new suit.
