"Chad, you're really my Speedo?" Thad hissed uncertainly at his crotch after making sure he had moved out of earshot of his teammates.
"Where are you going, Thad?" Rick shouted, "Pool's this way."
Thad turned and shouted back, "Gotta use the john, Rick!"
Rick saw Thad's tented Speedo, and laughed, "Yeah, I can see you do. Don't be too late or coach will make us all swim laps."
Thad blushed and darted into the nearest bathroom stall closing the door.
"You really were Chad?" Thad asked his suit.
"Goddammit, Thad, you know I'm Chad. Now change me back into a man!" Chad demanded.
"If you change back, I won't have a Speedo to wear. Coach won't let me be on the swim team if I don't wear a yellow Speedo, so even of I could change you back now, I won't. I can't go out there with you tented. And as long as you keep yammering, I'm gonna be hard," muttered Thad, "I can't believe it really worked. What did that book say on how to quiet the transformee? Oh, yeah, I remember..."
Chad was sputtering mad, "Th-then you admit it! You did th-this to me, Th-thad!"
"Well, I must've. I mean, it was just a spell I found in an old book. I didn't expect it to really work or work so well." Thad tucked Chad's pouch under Thad's balls, then he began jerking off
"Worked so well? You gotta be kidding!" Chad snarled in Thad's mind.
"Well. I did it kind of as a joke. There are video cameras in the field house that recorded everything. B-b-b-b-but will have t-t-t-t-wait f-f-for laaaaat-aaaaaaaah!"
Before he said "have", Thad pulled the yellow Speedo pouch back over his quivering erection. Then his cock began to explode.
As hot cum pumped out of Thad into Chad, Thad heard Chad go "Ggggggaaaahhhhhhh!" Then only silence.
Thad grinned as his penis deflated. There was no goo on his hands, no wet spot on his pouch, no noise from Chatty Chad. The book was right, "a full dollop of fresh hot man seed delivered directly into the one who was transformed will quiet it for an hour or more".
Thad assumed Chad was unconscious. Chad wasn't. He was fully conscious, and screaming at the top of his lungs, or so it seemed to Chad. Thad heard nothing, except for its remarkable absorbency, Chad might have been an ordinary Speedo.
Thad stood, farted loudly and flushed. Then he headed for the pool.
