Nemoc dangled Kasumi over the puddle of slime that had fallen from his massive, oozing cock. The mess bubbled, spat and then shot upward between Kasumi's legs. Her eyes went wide as the small amount of slime penetrated her and ignited her young libido as never had been before. She thrashed her legs, trying to resist, as mini-orgasms overtook her.
With his free claw, Nemoc tore the dress from her body, revealing her firm, erect nipples. He set her down in the slime, the strange liquid dissolving her boots and coating her small bare feet. She gneaded it with her toes.
Nemoc growled bestially and dove upon her, impaling her with his enormous penis. Kasumi gasped in pain and surprise as she somehow took in all 18 inches of him. A long forked tongue emerged from his fanged maw and teased her nipples as he thrust brutally into her again and again.
Pain turned to unbearable pleasure for Kasumi as buckets upon buckets of the demon's corrupting fluid filled her womb, excess bubbling out of her cunt, coating the caves floor. Kasumi's moans became deeper and stereophonic as Nemoc neared his third orgams. She closed her eyes and bit her lip. When she reopened her eyes, gone was their human beauty, replaced with fiery, reptilian pupil slits.
She wrapped her legs around her attacker now, thick black claws sprouting from her slime-dripping toes. "Yes! MORE!" she begged, licking her lips with a forked tongue. "MORE!" She dug her fingernails, now long black talons into his scaly back. She squeeled perversely as a whiplike green tail sprouted from the base of her spine.
Her skin began to take on a green hue, flesh hardening into fine, nearly invisible scales, spikes shoots out from her elbows and heels. Her breasts swelled to a large C, nipples turning black and leaking Nemoc's spunk. Muscles became atheletic and her body matured into a seductive, feminine, albeit demonic, figure.
Both demon and newly transformed demoness orgasmed--a mix of snarls, growls and moans--as Kasumi's teeth became fangs and black horns sprouted from her forehead. Her hair turned dark green and grew to her waist. Kasumi shuddered in pleasure as Nemoc withdrew.
He licked the excess slime from her pussy, drawing a pleasurable hiss. She felt her clit enlarge to the size of an enormous, retractable tongue and she shoved it into her master's mouth, "kissing" him.
Nemoc stood and looking down upon his demon slut. "Now, my defiant little princess, shall we break that annoying seal?"
Kasumi growled. "Yes, my master."
