She decides to thank him

Johns mom looks at him and says well thank you son I didn't know you could do that. He says yeah but that's not the only thing. She goes well I guess I need to test myself out real quick. John then says ok well have fun. He then sits on the couch and decides you know I am going to grow myself. He then massage his dick and balls and his dick grows to 12 inches long and a bout a half dollar wide in girth. Then his balls become the size of softballs and eventually can spews gallons of cum.
