Mario couldn't believe how well his spell had worked.
Seeing Adam's giant member was such a turn on for Mario. He pulled his shirt off and knelt down in front of Adams's incredible package and started moving his hands along the majestic shaft.
Adam gasped from the incredible feeling. "Oh fuck, that feels good," he moaned. Mario didn't wait very long before he let his tongue in on the action. He licked Adam's cock up and down. It was too much to fit inside his mouth, but that didn't matter. It felt so hot and tasted so good.
After a few minutes Adam started breathing more rapidly. Mario knew Adam was about ready to burst. "I wish you'd grow bigger as you orgasm," said Mario while he continued stimulating Adam's dick.
Sure enough, as Adam began spurting jism all over Mario's face, his body started tingling. His arms and chest swelled, filling his shirt more and more as his dick spasmed releasing load after load. The seams began to tear apart as the fabric of his shirt couldn't contain the volume anymore. Those huge balls Mario had already conjured up held a lot of semen, so Adam was able to orgasn for a while. By the time he finihed, he was over eight feet tall.
