Denzel fell into his recliner before his TV and turned it to the local professional sports team. They where playing their rivals tonight and being able to watch it all and not have to go into work tomorrow or the next day would be great. He would have gone to a bar to enjoy watching there but his 21st birthday wasn’t until tomorrow so he legally couldn’t drink. Still tomorrow maybe he would hit a few bars, in the meantime he opened a car of beer. Just because it wasn’t legal for him to have it didn’t mean he didn’t have it and took a long pull.
He began to veg out watching the game, it wasn’t that good of a game, it wasn’t that it was a blow out but instead of each team scoring multiple points it was a defensive fight which board him. His eyes began to glaze over a bit as he felt sleep or something else come over him.
Still he watched the game, his whole body feeling weird but mostly his feet.
What he failed to notice was that at one point his ankles had fused together into a single point and that fusion was moving up his legs at a slow and steady pace. His bear feet snapped so that the heels touched each other before they too fused together before they expanded outwards forming a fin.
Loss in the game Denzel didn’t notice as his fused legs went up to the knee as the very bones within his lower legs became one powerful one as more muscles formed around them.
He did think something strange was off but that was only because he suddenly had the urge to pleasure himself. He leaned backwards, failing to notice the chair groaning a bit from the weight of his tail as it expanded in length going over two feet longer than where his feet would have ended.
His hand reached into his shorts and he began to pleasure himself.
He didn’t know that was totally normal during the change, he took his manhood within his hands and began to stroke it. It felt so good as it speed up the transformation.
As he did aqua green scales began to grow on his now fused legs even as the fusion moved upwards causing his shorts to rip apart.
The sound of his shorts ripping caused him to stop mid stroke before he looked down to see his dick was now coming out a fused tail of aqua green scales that covered his now fused legs.
“What the fuck?” asked Denzel not sure what he was seeing or if he believed it.
