Luke immediately started undressing himself as he recalled the costume clerk instructions to strip down. A necessary per-requisite the costume. Though strange, he couldn't argue with Ben's and Jake's results from human to full blown wolves.
Standing naked before the bathroom mirror he held up the wolf-taur costume in total fascination of it. How realistic the fur was, and various other details. Still impatient, he started to wonder how was he suppose to wear this costume? Didn't a one person costume to fill it in. He'd rushed out the costume shop after paying and wasn't really paying attention at all. So, he improvised.
"I probably have to wear the bottom half of the costume first, then figure the rest later. Hopefully this will work." Luke said to himself in self doubt. Best not to leave this unfinished.
Holding up the bottom half of the costume looks pretty much like a regular four legged feral wolf. Missing the head of course. From the back he unzips and fits himself in as a regular costume. It even almost like fitting in some footy pijamas of a child. Though, he adjusted his dick piece, that envelopped his dick like a condom. As he fitted it, that cock piece started envelop his whole penis as is pumping it inward. The change was starting quickly. His Dick slowly added itself some inches, the mushroom head started to dribble some pre cum as it extended itself outwards into a point.
"Ohhhhh....man, this is intense" Luke said, as he was enveloped in waves of sexual please. He stroked his balls with both hands which helped to speed up the change. The balls inflated and slither out from a furry sack. Looking down he noticed he gained a wolf's dick pulsing with pre-cum. All the while he didn't noticed from his neck down his fur tucked itself to his skin. Merging itself to a true sense of a wolf's coat of fur. With the long bushy tail connecting unto his spine.
While Luke kept stroking his new member and exploring his body he failed to notice....
