Numerous Body Swap Stories

Struck by Lightning by thetfchangingroom

It was raining more that day than it had in months, and Peter was dreading having to walk home from class. He'd forgotten his umbrella back at the dorms, so he'd resorted to just running through the downpour as fast as he could (without slipping) all the way home.
But home was still a ways away, and Peter found himself wet, alone, and practically in the middle of nowhere. Dammit, he thought to himself, these clothes are going to be soaking by the time I get back.
At that moment, there was an all too familiar CRACK, and a flash brighter than anything Peter had ever seen. He only had a second to register what was going on before the lighting hit and everything around him went black.
Am I dead? No, he was still alive, thank god. After a moment or two, Peter realized he had fallen to his hands and knees, and was panting as the rain continued to pound on his back. Had he survived? Was this some sort of miracle?
But as Peter started to get up, a aching pain surged through every fiber of his body, forcing him back onto the concrete. What was happing? Was I hurt? What's wrong?? But before Peter could ask any more questions, the changes started to begin...
First, he felt his whole body get warm. Really warm, in fact. So warm that the rain was starting to turn to mist on his back. He didn't have time to take off his shirt because as soon as he moved his hand, he felt the aching return. This time it was different. This time, if felt like every one of his muscles had their own heartbeat, and were throbbing in an increasing rhythm.
Peter looked down to see them writhing under his jacket, molding themselves. Growing and inflating so they stretched the wet fabric on his arms and over his chest, There was another crack, but instead of lighting, Peter felt his back bones shift, rearranging themselves into a much broader frame.
"GrrrAAAAAGGGHHH." Peter let out a mighty roar as the now feeble sweatshirt split along the back, making a loud ripping sound and exposing his hot skin to the cool rain above. It was now turning to steam on his hot back, which was growing more and more with every breath.
His arms were next. His biceps tore at the arms of his sweatshirt, and his sleeves began to roll up his new veiny forearms as his arms began to expand into those of a professional bodybuilder, the mounds on his biceps now thick as hams.
Peter then felt his chest begin to surge. His stomach jumped and his back arched and Peter watched in astonishment as his pectoral muscles, perviously nonexistent, inflated like two large balloons on his chest. His shirt ripped down the front, and he thought for a moment that he had grown breasts. But when her felt them with his larger, rougher hands, he notices they were firm, muscular.
Damn, Peter thought to himself, I could get used to this. But before he could think anymore, he keeled over again, this time his abs curling up and defining themselves into a rock hard six pack.

His legs tensed up as he felt this thighs grow and burst through the seems of his pants. His feet, previously a size 12, were now struggling against the rubber and fabric of his soaking wet running shoes. Two loud pops and Peter knew he'd lost those as well. What was he becoming??
He felt his face shift, his nose getting smaller, his jaw becoming more defined. His felt the tickle of his hair as it grew down to his shoulders, and the prickle of a manly beard forming on his face.
"What is-" Peter tried to speak, but his voice dropped very suddenly. It now sounded much deeper, authoritarian, like he was some sort of god.
His clothes were in tatters, all except for his bright red underwear, which hugged the only part of him not throbbing with new muscle. As if whatever it was that had changed him read Peter's mind, He felt one last ache and surge of power, directed this time down towards his pelvic region.
His glutes ballooned out, and Peter grabbed his ass, felling it grow right through the wet elastic in his fingers. He couldn't tell if it was the rain or his own sweat, but whatever it was, it was a huge turn on.
Finally, Peter felt the very last muscle on his body grown warm in preparation for expansion. This time, he didn't ache, or feel pain. He felt the horniest he'd ever been as his cock started to grow in his underwear. It grew and grew, stretching the elastic until he could see the outline of the skin pressing up and waiting to be freed.
He bellowed on more time, throwing his face to the stormy sky and letting out a powerful cry of ecstasy as the fabric tore and all ten inches of this thick, hard dick shot out and into the cool evening air.

A few moments passed where Peter, just kneeled there, on his knees, panting and admiring his brand new body. He grazed his rough hands over every inch of his chiseled muscle physique, flicking his nipples and running a finger down the crack of his ass. He didn't care if anyone walked by, he hadn't felt this sexual before in his life.
As if saving it for last, Peter ran his hand over his cock. Testosterone shot up through his body and he shuddered with immense pleasure. Before he knew it, Peter was stroking off, the rain still evaporating around him as his body grew hotter and hotter and hotter.
He closed his eyes and moaned loudly as he felt all his muscles begin to tense up. He groaned in his deep new voice. "Ohhh.... oh god... oh fuck!"
Another loud CRACK as lighting began to strike all around him. As it did, Peter came. He bellowed loud as rope after rope of cum spewed from the tip of his monster cock, his body contorting as it was wracked with the greatest orgasm Peter has ever experienced in his whole life.
When the sky was done shaking and Peter had stopped writhing, He picked himself up off the ground. His whole body felt alien, moving around in it, feeling his weight as he shifted from side to side. But it didn't matter. He had to get home as soon as possible. Back to Asgard, where he knew his father Odin would be looking for him.
Thor chuckled a bit at the thought of being caught in the middle of a storm buck naked, but it excited him as well. He smirked, and sauntered off down the road in search of new clothes, a war drink, and maybe a beautiful woman or an handsome man to keep him warm for the night.
Assuming they can handle me, Thor thought with another chuckle, glancing down at his horse cock and striding back to campus, the rain around him finally beginning to subside.
