In the end, Dustin decided it would be safest if he only had some of the serum right now. Actually, not having it at all was the real safest bet, but he really wanted to know if it would work or not. With that in mind, he popped the cap off the vial and put the mixture to his lips.
The taste was something that he couldn’t work out, seeming to be like saltwater, fish, and a few other things, and being as thick as it as, it held on his tongue for some time leaving a weird aftertaste. After that small mouthful, he looked to see that about one-third of the mix had been drunk so far, as he recapped it and a wave of bliss washed over him, almost like an actual wave.
With an almost detached feeling, Dustin could feel that something was happening to him, odd pulls and tugs at his spine while his skin felt thicker. He was vaguely aware that his spine was becoming longer as something pushed out of his back, about between the shoulder blades before the sound of tearing fabric pulled him out of his lethargy.
Almost toppling over, another tear came from his jeans thanks to what had to be a tail forming while his shirt buttons tore loose thanks to his expanding torso. Staring at himself, he could see his skin changing in colour now, a two-tone scheme of black and white replacing the original pinkish skin with his body hair falling away in clumps.
Kicking the remains of his ruined attire free, he stumbled towards a mirror where he witnessed his face pushing out into a more streamlined shape, his eyes almost hidden by the contrasting colours of his new form as a large horizontal fin emerged from his completing tail.
Soon enough, it was over and Dustin could see clearly that the serum had been no joke, he was now a mix between Orca and Human, though slanted heavily towards the Human end of the scale, given his still external genitalia and its still human-like design as an obvious indicator. He also had quite the physique now, even through the thick flesh, well defined muscles could be made out, especially when he posed for himself.
There was one problem he could see though, a search through his belongings after heading to his bedroom showed that almost all his clothes couldn’t fit him anymore, only a pair of heavy boots that he hadn’t been able to wear since they’d been ordered at a too-large size. With just them on, he paced around slowly as he considered his available options.
About a half-hour away (walking) was the nearby gym with an impressively large swimming pool, he could go there to check out his new limits and capabilities if he wished. The beach and harbour were 45 and 30 minutes driving time away respectively, where he could go for the same or of he wished to take more of the serum. Although he could take more of it now if he wanted to, in fact, he could feel himself wanting to right now. Then he could wait here and see what happened, which given his ultra-limited wardrobe might be a good idea. Finally, there was the skate park that he could reach in 15 minutes. A thick hand under his jaw, Dustin paced around the house as he worked out what it was he wanted to do.
