With that, Dustin was beginning to feel quite happy with his jokey new powers, when he saw a young man at around the age of 21 enter. He was wearing a blue T-Shirt, beige Shorts and blue Sneakers. Upon taking them off, Dustin could see the man was wearing white Underwear and so, that is when the fun soon began.
"This is gonna be good." Dustin chuckled. As for the man, he took off his shorts and went towards the wall mirror. He looked at himself. The man suddenly felt his undies feeling tighter. Looking down, the man had noticed that his cock was elongating and his genitals bulged out. Unlkie the boy Dustin had grew earlier he let the man's clothes tighten. They didn't tear, but continued to shrink on the man's expanding sex appeal. His muscles were also growing dramatically. The man, confused, ran into a toilet stall and locked the door.
"What is happening to me?" the man exclaimed. He closed the toilet lid and sat down just when a 10-Pack had formed on him. His pecs pushed out greatly and his biceps grew equivalent to that of a Truck Ture. As for Dustin, he was having a whale of a time! The man had a 20 inch cock, balls the size of a miniature globe and 10× more muscle than before. The man ended up outgrowing the stall and blew out the side walls then ran out. He looked in the full-wall mirror and saw his gigantic new body. His bulge also began to feel like it was filling up with jelly and soon, pee came out and soaked the crotch area. His blue shirt was straining on his huge muscle mass and the Underpants were just as tight. The man soon grabbed his clothes and shoved them into his bag before looking around and flexing. That is when he headed for the 'Staff Only' way out.
"Alright, I need to get home without anybody seeing me like this." the man said to himself. And with that, he opened the door and left. Dustin just looked, stared and fell to the ground cackling with pure laughter.
