Rachel wandered through the house after her gift to her mother and stopped in front of a large mirror in the hallway. She examined her nude form slowly, her eyes drifting from one part to another as she tried to take in all of its splendor. From her heavy DD cup breasts, to her shapely hips and perfectly sculpted rear, to the seductive gleam she got in her eyes as she flashed her fangs.
"I look amazing! I am loving everything that's happening to me." Her 10" cock swung from her crotch enticingly, the sensitive spines along it's length having retreated, making it look normal besides it's size. "Thank you whatever is causing these changes, I love them."
Her self admiration was interrupted by the sounds of a conversation outside her house, something her new pointed ears listened in on easily as she peaked from behind a curtain.
Next door she spotted her neighbors getting into a car and waving their last goodbyes to their 2 sons on the doorsteps. It was obvious to Rachel that the 2 were leaving on a long trip, given their luggage in the car. The two on the doorstep were so different; One was clearly a gym rat with his bulging muscles beneath his tank top, while the other was more a bookworm, thin and unassuming, but not unattractive.
"Well hello, new toys." Rachel grinned and started upstairs after she saw the car depart. She opened the box and looked around at the chocolates for inspiration for how to get them to eat. Her eyes fell upon the lamp chocolate. She wasn't sure why, but she sensed something powerful in it, like it might hold her answers.
"I wish I knew how to solve this problem," she murmured and ate the chocolate. Instantly Rachel felt herself tingle and a creative idea came to mind....
----Later That Night----
Rachel waited impatiently for the sun to set before she enacted her plan, all the while her mother was still out cold from her hardcore fucking. Using the cover of night, Rachel snuck up to the neighboring house and heard the sounds of some game from the above window. Holding the box in one hand, Rachel climbed up the vine cage on the side of the house dressed in a tight fitting t shirt and leggings. She nearly burst out laughing when her prey stumbled out of his chair upon seeing Rachel outside his window. Before he could call his older brother however, Rachel caught him in her newly gifted hypnotic stare. She willed him to come to the window and let her in.
As he walked over, Rachel took the opportunity to think of what she wanted to do to this thin boy. His messy blond hair nearly covered his eyes, but Rachel saw his light blue eyes beneath the bangs. As the window opened, she slunk inside and realized how she towed over the nerd, by nearly a foot if she guessed. He stood before her, patiently awaiting an order while his character died in game behind him.
"What's your name?"
"Charlie," he answered hypnotically.
"Well Charlie, take off your shirt and pants." Charlie obeyed and revealed his hairless unremarkable chest and legs, leaving only his briefs. He actually looked adorable to her, and she got an idea. She ordered him to sit on the bed and eat the chocolates. Rachel opened the box and pulled out a dark penis and balls chocolate and put it into Charlie's mouth. He obediently ate it and momentarily squirmed as his pants bulged slightly. Rachel continued to funnel a steady stream of the chocolates into her subject and eagerly watched his underwear bulge with each piece of candy.
------
Charlie was vaguely aware of the changes, more so as each growth lessened the woman's grip on him. However he found he didn't care, he just enjoyed the feeling of his changes. His crotch continued to tingle and expand, with the once loose underwear becoming more constricting. After his fifth candy, it looked like an orange was shoved in his pants, by the ninth a pair of oranges, and the hypnotic spell was broken.
"Who are you?"
"Aw, awake. Guess I know my limits roughly. I'm Rachel from next door."
"What are you doing to me? Why?"
"I'm giving you a gift sweetie. Should I stop?" She gave a pouting expression.
"No!" Charlie answered quickly.
"Open up."
She continued to feed him candy until, with his legs being forced wider as his balls grew bigger and bigger. Charlie forced himself to stand and nearly fell forward from the weight. With a ripping of fabric, the underwear lost the fight and let the now melon sized balls droop down between his legs. What interested Rachel was the python above the pair of balls. It dwarfed Rachel's own with its 2 feet length. And still it continued to grow even after Rachel stopped feeding him.
"What's happening to me?" Charlie asked in a panicked tone.
"Becoming the envy of all studs. Lay back" she commanded and disrobed excitedly.
Rachel pushed him on his back and mounted the large tool. She grabbed Charlie's hands and made him begin to caress her breasts. She rocked back and forth as the cock continued to grow slowly inside her.
"I don't wanna hurt you," Charlie fretted.
"Adorable, but not needed. I-uh am fine. Uh! Now fuck me!" She demanded and began rocking even faster as his cock began to lift her higher. Behind her, Rachel felt something rubbing against her ass and looked behind her. His balls had grown to watermelons and were nearing pumpkin sizes.
After a few hours of frantic fucking, Rachel felt Charlie was about to cum. Her own member was twitching frantically as well.
"Cum in me fuck toy!" She demanded.
Charlie nodded and clenched his miniscule muscles as his load shot through his length. In response to feeling her insides being flooded, Rachel let her own load loose on Charlie's face. But while her load was tapering off, Charlie's was continuing to fill her. Rachel watched in disbelief as her stomach ballooned out like an accelerated pregnancy.
'I'm gonna pop,' Rachel almost panicked before she realized it didn't hurt, but felt pleasurable.
Finally she felt his throbbing taper off and his cock become flaccid. She smiled at the panting and smiling man below her and thought that he'll do nicely. She slowly stood up and rubbed the taunt skin on her belly. It looked as though she was past term with triplets at least, but she still looked stunning.
"Th-thank you."
"No problem. Come over anytime for more fun. Now I've got-" she gasped and clutched her bloated stomach. "Wh-what?" A gurgling sound could be heard as Rachel's belly slowly deflated and she felt an intense surge of power flow through her body. With this power, she felt herself change. Her breasts grew to plump F cups and her entire body grew upwards another few inches, stopping at 6' 8".
Rachel licked her lips and smiled. "Time to visit your brother."
