He paused as a euphoria entered his body. A slight groan escaped him as he felt himself grow.
"Yes!" he gasped as the seams strained and his pant legs, shirt sleeves, and hem all rode up slightly. He growled, "Fuck yeah!"
He grew more and his shirt no longer could handle his bulking body. His sleeves tore open and a tear formed at his neck and stretched down. Now full out moaning, right in front of Tony's door no less, he gained several inches in height and size, his body adding mass rapidly.
As his shirt fell away, his hands roamed his body, and he took notice of something that seemed as excited as he was. His cock had grown signficantly, creating a major bulge in his pants (which were shredding up the sides of his thighs).
"All fucking right!" Brendan bellowed, followed by a low groan.
"What in the fuck is wrong--" Tony said as he opened the door on the growing behemoth, "Brendan?"
Just as Brendan smiled at Tony, the remnants of his pants exploded off, revealing a young nude god.
"Fuck," Tony said, "Fuck, fuck, fuck, you're so fucking hot! Get in here RIGHT NOW!"
