When I grow up I wanna be a fireman!

While eating yogurt, his body is growing to manhood with stretching and groaning sound coming from his rapidly maturing body, first limbs stretching longer and tearing his fireman costume. His belt broke first, then his jeans popped open. Every button also burst off his shirt, followed by significant tearing and his feet having broken through his boots. Shirt ripping open to reveal a hairy chest and a mature young man’s mug reshapes from his childish face, leaving the young lad in a man’s body in a tight torn firemen's costume. He releases what happened to him then scream with his still young voice

Mom!!!
