"Isabelle," Max began, watching her eyes flick to him. An idea was forming in his head. "You're a nymphomaniac. You love sex, and you're constantly horny."
"I love sex, and I'm constantly horny." Her pussy was beginning to drip, and a dark patch began to form on her pants.
"You're attracted to people of all genders," Max continued. "You love guzzling down any sexual fluids you can find. In fact, you're completely addicted to them, especially your mother and aunt's milk."
"I love drinking cum and milk," Isabelle replied, mouth watering. "I am addicted to my mother and aunt's milk."
"You can live off only sexual fluids. You can drink an endless amount of them, and still not be full."
She repeated his words, and her stomach growled. She was so hungry, her stomach so empty. In the background, she could see her sister fucking her aunt and mother as hard as the double-dicked wolf anthro could. She wanted that. She wanted her sister's cum so bad, and she wanted to suckle her mommy's milk until her huge breasts ran dry.
"Now, Isabelle, you can feel your body growing elastic and pliable. You can take any insertion into any hole with ease." Max smiled, and continued, "When you drink breast milk, you grow stronger and more powerful. When you drink girlcum, you grow taller. When you drink male cum, you grow more muscular. Anything you absorb into your pussy transforms you into your partner's perfect sexual fantasy. Anything in your ass makes you more hypnotic and attractive."
Isabelle shudders as the changes take place. "I will change as they fill me up," she intoned.
"Good. You want to go drink Mommy's breastmilk, don't you?"
"Yes."
"You're going to go over there and drink as much milk and cum as you can, Isabelle. When I say 'awaken', you will milk your sister, mother, and aunt dry, and become the perfect, submissive nympho slut that you were always meant to be, understood?"
"Yes, master."
"Very good, Isabelle. Awaken!"
The spirals cleared from her eyes, and she shook her head as if waking from a dream. But once her mind threw off the fog of hypnotism, it landed on the fuckfest taking place in front of her. Melody had finally finished in Alison and Britney's asses, and the two were leaking her seed onto the floor in their post-orgasmic bliss. As Isabelle crept closer, her Amazonian sister's gaze fell on her.
"Well, hello there, sis," the anthro wolf purred, body language turning sly and sultry. She swayed her hips as she strode closer. Two of her arms rested on her twin cocks, now beginning to harden the longer she stared at the human girl in front of her. Two more pushed up one pair of her breasts. Her huge, muscular body collapsed as she leaned down to give Isabelle the most seductive kiss anyone had ever had. "I'm ready for round two. Are you?"
"Yes!" cried Isabelle. Her face was flushed with lust. She stripped off her clothes with needy fervor and presented her sister with everything she had. Though the 5-foot dicks completely dwarfed her whole body, she knew she would be able to take them with ease. Melody did too, and she growled as she grabbed her sister by her ass and slammed both shafts into her at once - one in the ass, one in the pussy. Isabelle kept her mouth busy by forcing not one but two of her sister's 12-inch dick nipples down her throat at the same time. Melody growled and willed them to orgasm, painting Isabelle's throat white with a gallon of seed, while her top pair of arms pulled at her hair. Isabelle swallowed the load effortlessly, and moved onto the second pair of breasts, eager to gather as much seed as possible.
Even as her eight breasts were being pleasured, Melody did not slow her pace. If anything, she only got more wild and feral, howling as she filled her sister's tiny body to its limits. Her cocks were swallowed their hilts by Isabelle's insatiable pussy and ass. Melody slammed them in again and again, each one rougher than the last. Isabelle took it all, moaning as she swallowed more and more cum. In Melody's hands, her body hardened and grew larger, muscles now becoming prominent on her frame. The ass that Melody gripped was no longer soft, but two hard cushions of thick muscle. Still succulent and pert as ever, though, and Melody wasn't about to stop pounding it.
Then, just as Isabelle was on the verge of orgasm, Melody's thrusts stopped. Her claws dug into Isabelle as she howled and moaned. Deep within, her knots expanded. "Fuck, I'm going to cuuuuum!"
Both girls shrieked in pleasure as they came in sync. Melody's four, heavy balls unloaded into Isabelle's tiny body, but her size didn't stop her from taking it. She held those gallons of cum within her with ease, feeling full and warm and happier than she ever had before. She hugged her sister tight, stuck to her by the thick knots that plugged her ass and pussy.
But with all that cum in her, Isabelle was about to change. The question was, what was Melody's ultimate fantasy?
