You couldn't hold it in.

Your cock throbbed and pre spewed onto the concrete. Steve's ass continued to fatten and wobble. It grew twice as tall as him. Steve moaned as it widened and spread until it was easily three times as wide as he was. His legs, especially his thighs, got lost within the simply enormous magnitude of fat piling onto his ass. And then the hair began to grow. Steve's ass was hairy before, but now a forest of sweaty hair began to sprout all across his magnificent posterior. Your assistant nodded to the obese one-ton worker as the man handed Steve bag after bag of food. And then he walked toward you. With just one stomp his enormous ass shook like jello wobbling left and right.

"Fuck!" You shouted as your cock erupted. The firehose of white cum blasted across the parking lot and into Bigger Burger flooding it within moments to the cheer of everyone inside. Your balls seized and pushed against your backside as you grabbed whatever fat of your moobs you could to play with it and egg yourself on. Not for one moment did your eyes move away from Steve's ass and its quaking as it moved closer and closer to you.

"Oh, sir!" Steve shouted. "I'm so sorry, if I had known you were so close to blowing your load I would have taken your cock first." Steve finally reached your cock and intercepted your load accepting it with glee as he turned his massive body around. You watched as the towering cheeks finally stopped and wobbled left and right before backing into you. Your load blasted into Steve's ass and splattered everywhere before it finally was plugged.

"Holy shit!" You shouted as your cock entered Steve. His ass cheeks towered above you and still moved closer before meeting your prodigious belly. You began pushing harder. Your belly spread and squished as you could hear Steve moaning from across his mountains of ass. "Your ass is amazing." you moaned.

"Thank you, sir!" Steve shouted in pleasure. "I've been working so hard on it for you. You deserve a good fucking whenever you want it!" You continued to howl in orgasm before finally reaching resistance as you couldn't push forward anymore. There was just too much ass and belly between you two. Your legs finally gave in to weakness as orgasm wracked your body and you fell to the ground. Shot after shot of cum blasted into Steve and all you could do was sit there and enjoy it.
