"Wow, it really is you, Chad!" Bruno explained. Then he looked confused. He rambled, "I've got no idea how Josh did this to you, let alone how to change you back. I can't hide you around here. I can feel your lips moving, but I can't read lips and I can't hear you. Oh, but it does feel good. Hm? You're smaller than my Speedo, I know where to hide you. And I'll always know where you are and Josh would never think to find you!"
Bruno picked up his Speedo, and wearing Chad dashed through the hallways to the Home Economics Room. He entered, and made a beeline to the area where the stoves were lined up. There were always extra cookies and pastries in the refrigerator behind the stoves. He munched down some chocolate chips.
Then he headed to the rows of sewing machines, and peeled off Chad. Then he flipped Chad inside out, and set Chad inside his own larger Speedo.
Chad tried to scream and shout, but Bruno couldn't hear him, and was so focused on his work that he didn't notice thr frantic expression on the pouch of his new Speedo.
The machine whirred to life. Bruno knew his way around a sewing machine. He had learned when he was younger in order to repair torn Speedos and to make his competitive ice dancing costumes. Sewing a new liner into his Speed was easy. First he removed the drawstring and liner from his old Speedo. Then he set Chad inside it. He carefully stitched the two garments together joining their seams. Chad's drawstring was now both suits' drawstring. He constantly checked the seams before adding more stitches. Chad nearly passes out from the pain. He was sobbing, as naked Bruno stepped into him. This time Chad's focus was inward staring at Bruno's cock and balls racing toward him. Bruno shaved his body including his pubes to reduce drag swimming. He also insisted that shaving his pubes made his cock look bigger. On this final point, Chad could agree. As Bruno's manhood smashed into Chad's face. It was huge!
Bruno cleaned up content with his good deed. He headed back to the locker room to dress, but first another swim.
