Dustin spied a kid in a Speedo. The boy was attempting to get a new suit for his tryouts for the team tomorrow. By the looks of it his cock was about average, but that was about to change. Dustin focused on the boy. His cock began to lengthen and thicken along with his balls, and the Speedo slowly began to bulge outward.
As his cock passed 8 inches and his balls reached the size of eggs, the boy became aware of a stretching sensation at the front. Looking down, he saw the bulge and was impressed, thinking the Speedo was accentuating what was already there. Dustin continued to stare, further elongating the boy's cock. As the strain increased, the boy's face began to contort in pleasure and pain. He writhed, his now 10 inch cock and small apple-sized balls pushing and deforming the suit to the max...
RRRRRRIIIPPPP. The Speedo finally sheared clean off. The boy's foot long cock and enormous balls flopped out, and almost immediately began to harden. The boy looked like he was going to cry, he was so happy.
