She should do it herself

Aiden stayed firm in his decision to let Grace be the one to infect herself. He only had to wait, though it was difficult to hold himself when her wet pussy continued to flutter around his head. No harm in giving her a little encouragement though.

"You must take a leap of faith, Grace. No one can do this but you. Show me your dedication," Aiden whispered to her. Grace looked up at him, her hazel eyes meeting his sharp blue. Her expression hardened and a moment later, she pushed herself down on him, taking half of his ten inches at once. She screamed at the intrusion, but the deed was done. Breathing heavily, she slowly acclimated to his thickness inside her. She only waited a moment before experimentally moving her hips. Her eyes went wide, and she slowly repeated the motion. Her small thrusts steadily became larger, her breaths becoming deeper.

"Ohhhhh, Master," she groaned, allowing herself to sink a little further on his cock. Her eyes burned with lust when she looked at him again. "Master, is this what it is? Why would I resist this? This is-" her voice faded as she experienced her first orgasm, momentarily overcome by the pure euphoria of it. She came down slowly, her eyes already shifting away from their hazel color. "My Master, please.... Please fuck me.... However you want. Just...fuck me hard. I need more."

Finally satisfied that she had embraced her desires, Aiden flared his wings and laid Grace down on a nearby table. He detached his tentacles from Abigail's chest, her boobs now a massive, jiggling h-cup. Cum leaked out of her even further engorged nipples, along with traces of the milk she was now producing. Carson was quick to replace them, blowing his second load inside her steaming pussy at the first taste. Ryan and Dex were similarly enthusiastic, and hesitance from the former completely gone as they pushed against each other, Dex's new, larger frame overshadowing Ryan's comparatively slim figure, one arm wrapped around and jerking Ryan's mutated, mushroom cock.

"Master, my Lord, please don't make me wait any longer," Grace whined from beneath him, her legs wrapped around his waist, trying to get as much of him inside her as she could.

"Don't worry, slut," he said harshly, Grace's eyes going wide with arousal at his husky, impassioned voice, completely different from the gentle persona he had adopted a minute before. "I'll fuck you good and hard so that you never forget who you belong to." He pulled out of her slowly, before slamming himself back into her cunt, making her yell in pleasure. He continued the alternating rhythm, keeping the woman between anticipation and blasts of pleasure, her senses running haywire.

"YES! YESYESYES!! FUCK ME DEEPER, MASTER! Pound your slut! I'm yours, my lord! Fill me with your glorious spunk! Make me yours forever!! Infect me with your essence! CUM INSIDE ME!!!" Her yelling reached a fever pitch as her pussy clenched around him. He didn't bother to resist his desire to cum any more, eager to see her transform. With a yell of his own, he pushed himself as far into her as he could, bumping up against her cervix as his balls churned and his cum shot into her constricted tunnel. Grace thrashed at the sensation of heat spreading inside her, reveling in it and her own surrender to him.

"What am I to you?" Aiden growled in her ear, thrusting into her as he continued to pump burst after burst of cum inside her. "Who am I?"

"You're my master, my lord, my king, my soulmate, my owner, my GOD!!" she shrieked, orgasm after orgasm tearing through her, her skin paling with each one until it became a glowing white. Her brown hair lightened to a radiant blonde, flowing and curling like strands of gold. From her back grew large feathered wings like Aiden's own, which twitched as nerves grew only to immediately be caught in the feedback from Grace's continuous climax.

"And what are you?" he roared at her. Eyes clouded with lust and pleasure slowly opened, looking at him in adoration. "Tell me what you are!"

"I'm yours, Master! Your ****, your slut, your fuck bucket, your cum dumpster, your whore!! I belong to you!" she moaned huskily, fully embracing her redoubled need for sex and pleasure that she had tried so hard to suppress.

"That's right, bitch. Now I think its about time you looked the part." Aiden came again, the thought of what Grace would become enough to make him find his release again.

Grace's eyes rolled up as further changes rolled through her body. Her breasts and ass, which hadn't grown from their slightly below average proportions, now ballooned outwards, her butt becoming a plush pillow, hips widening to form the bottom part of an hourglass. A moment later, her breasts grew explosively, filling out like she had always secretly hoped they would when she was young. Now they surpassed that size, becoming gravity-defying peaks of feminine perfection that bounced at the slightest movement. Black bled into the white feathers of her wings, spreading until her entire wingspan was a lustrous black. Her blonde hair lightened even more, becoming a pure white. Finally, her eyes changed fully from hazel to a burning red full of passion and devotion.

"Oh, Master...you're so perfect.....thank you...I love you......," Grace mumbled as her breathing evened out and she fell asleep, completely exhausted. She still moaned as Aiden pulled his slick cock out of her well-fucked pussy.

"Let's finish this up," Aiden said, looking at the two untransformed females, who had watched the show with wide eyes and burning arousal. "Which one of you is next?"
