Jonathan couldn't help but feel giddy from all the euphoria from the invasive tongue, moaning through the thick flesh as it continued to pulsate through his body. Unbeknownst to him, the mix of saliva and slime had begun to change him, absorbing itself into his body, all to satisfy the toad's desire for a 'princess'.
His body shape began to change, what little muscles he had slimming out into dainty arms, slender hands and a flatter chest. Facial features were slimmed and smooth out as his facial hair dissolved away, leaving silky smooth skin while his eyelashes appeared to have increased and curved. His hips becoming wider and his ass swelling out into a smooth, feminine bubble butt.
One would fear for Jonathan's male status, but oddly enough, the toad king's desire for a princess did not overrule his need for male courtship. Jonathan's cock and ballsack still remained, though now they began to shrink in girth, leaving still good sized genitals, albeit now slender and cute to the toad's liking.
Suddenly, Jonathan's mind became overwhelmed with even more horniness and pleasure as the toad's tongue began making a pumping motion throughout his entire body. He could feel certain parts of his body inflating, starting with his head as his eyes began bulging out, eventually stretching out his eye sockets to allow his darkening eye to slant like an amphibian's. His hands began to widen and his fingers becoming webbed in between each, while the tips balloon out into bulbous ends. His feet follow suit as well while his mouth starts to widen out to make room for his lengthening tongue inside.
His skin color began to transition into a vibrant bright green, unlike the king's dark green skin, with his belly and bottom of his wider mouth becoming a lighter, paler green, akin to the underside of a frog. As if to signify his changes finishing, Jonathan couldn't help but let out a croak from his filled throat, the underside of his head growing an air sac that inflated with the croak.
The toad king smiled as he heard the inhuman croak escape from Jonathan, letting his grip go and his tongue unravel from throughout his body. "And the coronation had been completed, my love." he says as he sets the newly made frog man down. He looked over his 'princess' Jonathan's body now a feminine hourglass shape, his body complete covered in slime and mucus his skin began naturally producing. Exhausted by the flood of pleasure and euphoria, Jonathan was sitting on the ground, though crouching his webbed hands and feet together naturally like a frog. His cute cock and balls hung spent in between his massive thighs as his air sac inflated and deflated in the place of panting. His eyes blinked their new transparent eyelids as he noticed the toad king motioning above him.
"Now, my princess! Let us create my kingdom anew together, as husband and wife!" he declared, holding his webbed hand out for you to take, his slimy cock twitching in anticipation from behind. As the euphoria began to fade, Jonathan responded...
