Although Dustin just came into the female shark and still was shocked about what was happening to him and what he had he had done, he couldn't deny that he felt some affection for his aquatic mate. Meanwhile the female shark has turned around again and cicled around Dustin while the rest of his human skin became grey and turned into the rough, sandpaper like counterpart that sharks use to have. While the shark was swimming around him, Dustin did his best to keep eye contact with her and the longer he did so, the more beautiful she looked for him. Finally he he decided to become active again and Dustin started to swim after his mate, moving his tail like he already had it his entire live. While doing so his arms started to flatten and stretched out along his body frame, turning into his dorsal fins and connectiong to the rest of his former hands. Additionally Dustin felt and, which was quite more amazing for him, saw his nose stretching out from his body while his mouth grew wider and attached to his growing nose. Dustin even got a better field of view when his eyes were pushed away from each other, allowing him to follow the female shark better. With that done Dustin posessed the full body of a shark and with this body predatory instincts appeared in his mind. And his mind told him that he needed to have this female right now. Accepting his new mind completely, Dustin rushed forward and caught the other shark quite easily. She was also willing again and exposed her body to Dustin and he bit into her pectoral fin to get a better hold of her before he pushed his already erected penises into her again. Due to his fully changed mind he enjoyed it much more than before and waves of lust ran through his body. It didn't take long before Dustin could feel his cocks throbbing even more inside his mate and also felt a kind of clenching feeling inside his body close to his slit and with a burst of arousal he unloaded his cum into her vagina. After this was done Dustim remvoved his maw from her fin again and pulled out of her, before the two sharks swam around in the aquarium like nothing had happened. During the whole time Ty just watched his former foster- brother transforming and mating. It was amazing what he actual was capable with his powers and while he stood there he was thinking about to turn his brother back and let him be aware what he had done or if he would wait with this until the trip is over.
