The boys each ordered two of the large burgers. They were anxious as they waited. When the four burgers came they each ordered four to go while they were still relatively human size.
They chowed down, devouring the first burger. They paused to grow, Kevin reached twelve feet while Jack hit nine. The waiter brought their 8 burgers to go and ran back to the kitchen. They scarfed down their second bureger and took their to-go burgers.
On the beach, Kevin now 16 feet and Jack at 12 feet, they continued eating. They were getting full the feeling of growing was too much and they forced themselves to eat. As they got bigger, the burgers were smaller and they simply tossed them in their mouths. Kevin grew massive and after eating his last burger topped off at 42 feet high. Jack stopped at 36 feet. The two giant bodybuilders still wore their magic speedos, which had grown with them, but at this size they didn't care about the rules.
They pulled down their speedos and released their mansized cocks. The giants began stroking and flexing each at each other as the beach goers watched in fear and awe. They took turns sucking their huge dicks in front of everyone, their young teenage faces contorted with pleasure.
They began posing, doing a bodybuiler routine for the normal sized men. All the guys on the beach began to relax, and soon a number of them had whipped out their cocks and were jerking off while watching the gigantic boned up hulks.
The two giant muscle boys were really getting turned on by the attention. Soon keving sat down on his giant muscled ass and began blowing Jack who continued flexing. A crowd formed in front of Kevin and they began rubbing their bodies all over his cock, trying to jerk him off.
Jack shot his giant load in Kevin and Kevin shot his massive load, covering the crowd with gallons of his cum.
Suddenly the two feel a rumbling in their stomachs.
