Each takes

With both boys now fully erect and ready to shoot out their loads. Pulling out for a final time boy 1’s 10 inches was completely wet but soon began to dry up and loose some of the hardness. Boys 2 having the same exact effect. Slightly loosing it’s hardness. Boy 2 repositioned himself next to his friend who was in position for yet another filling.

Each one ready the machine was making loud noises and grinding of gears. With both assholes pushed through the door flap and twitching their holes were entered by a massive head of a thick firm dildo. Each one was overly thick. Both groaned as the head slid into their holes.

Suddenly without warning a couple squirts of a thick liquid fired out of the tips. It began to harden immediately and both screamed out as it forcefully pushed through their colons. Another shot from the tip and each had a assgasm, more and more thickness pushed higher inside. A white thick lube like material flowed through the now 18 inches of dildo.

The liquid being slippery pushed everything even more. 24 , 30,36, finally stopping at 48 inches. A click from the machine, each one began to fill with the remaining gallons of warm water laced with erection making compound.

Just past the gallon mark the compound kicked in. Both boys cocks expanded to maximum length and girth. Gallon 2 produced a strong cramp and each screamed. Their cocks grew even more. Boys 1 10 incher grew to double.. 20 inches

Boy 2 ,8 inches to 16 inches. Each ones balls also grew bigger. 3 gallon mark and a cramp hit assgasm hit and their stomachs expanded.

The final ounces drained through the whole length busting through each 48 inch thick dildo nozzle.
