After Brad had the entire jug of water they rushed off to his appartment where they had sex.
He felt a tingling in his loins and his pants began to swell. She dug her claws into his pants and tore them away, along with his boxers, revealing Brad's erect 5... 6... 7.... inch cock. Mellony ran a hand over it, exciting him further.
"Mmmmm... I want to feel all of this," she purred and took in all--currently 8--inches of Brad into her moist, purple twat.
Brad felt his excitement soar. Finally, after all these years, he was finally fucking Mellony whom he secretly loved.
Mellony bobbed up and down on his cock, moaning like an unholy whore. She deployed several tentacles and began caressing Brad's face with them.
Brad felt a surge of strength as his muscles exploded to the size of a career bodybuilder. He used his newfound strength to grab Mellony by the ass and lift her off her feet. He carried her over to, and pinned her against, the kitchen wall.
Long ebon claws shot from his fingertips and he dug them into Mellony's rear, drawing further moans of pleasure from the demoness. "Yes, fuck me harder, Brad!"
Brad's own breathing became bassier and stereophonic as he felt his tongue lengthen and become forked. He ran it over the fangs growing in his mouth. His skin turned red and became leathery. A long spiked tail grew from the base of his spine.
Both creatures climaxed as Brad's facial features became more angular, his ears pointed. His two horns grew outwards while being shortly accompanied with another two just like them. Brad shot his enormous, black load into Mellony and she orgasmed wildly, coating him with purple vaginal fluids. The two creatures shuddered in pleasure, coated with each other's love mess.
