Amanda ran her hands over her perfect body. She brushed her taut thighs, ran her hands to her tight round glutes. She gradually moved her hands back to her small defined waist and finally cupped her large firm breast. Amanda was getting lost in the marvelous sensations that her enhanced body was bringing on. Wave after wave of pleasure washed over her.It was evident that his brother was out of his mind with desire, the bulge in his pants was even larger than before. Even though he was her brother, it seemed her new body REALLY craved sexual intercourse. Amanda could keep her desires in check only by constantly touching magnificent self.

More than anything Amanda revelled in the power she had over him. Gathering her senses she adjusted the gun.
Let's make this gradual, I don't want to become a freak. she thought. Amanda cranked up the height setting another 5%, which according to her calculations should make her close to 6'2". Looking at her toned arms she thought they could use a little bit more muscle amanda had always been a fan of the fitness models. At her new height she thought she could sport a fair amount of additional muscle andstill retain, even enhance her feminity. She adjusted the muscle setting to 40%. With the gun still in Robert's hands she aimed at herself and pressed the trigger.

Wondrous sensations once again filled Amanda's body, only this time they were more intense because she was awake. Amanda started by growing a little taller to 6'2", all the extra height seemed to come from her lengthening legs. Her pelvis seemed to shift forward a little bit making her butt even sexier and more inviting. Soon thereafter the extra muscle growth kicked in, bulges materialized out of thin air like she was being inflated from the inside. The demarcations between each head of her quadriceps, biceps and triceps became evident as more and more muscle poured themselves onto her expanding frame.

All that extra musculature seemed to know exactly where to place itself to even further enhance her sexiness, extra pectoral muscle pushed her enlarging breasts even further away from gravity's pull. Her skin took a more bronzed tone, further enhancing the demarcations between her muscle fibers. Her waist had etched itself with a deep six-pack. Even her facial features refined themselves some more, her lips plumper and redder, her eyes bluer, her beauty the envy of any magazine cover. Her platinum hair's sheen improved, and it lengthened to her shoulders as if it was too timid to obstruct the view of her incredibly physical perfection.

Truly she was a sight worthy of a Greek epic now. Statuesque muscled legs flaring at an irresistible angle to a rock-hard inviting ass. A tiny waist sporting a deep six-pack of abdominals. Her arms definitely had some size to them now, they were probably close to 15 inches around. Her heaving chest was the most impressive, each breast was larger than her head, yet somehow their size seemed perfectly balanced with the rest of her silhouette. Each sphere was incredibly firm yet supple as she grabbed them. They were not only oblivious to gravity's pull; they completely negated it, and then some.

It was now evident to Amanda that the more she transformed herself, the sexier she became, the more she craved sex. Every fiber in her being was crying for it now. Her pussy was thoroughly moist now, it's juices mixing themselves with the layer of sweat covering her body. Amanda could no longer hold back now, and she let her hand find her way to it's goal as she started fingering herself. As her other hand continued to grab her magnificent breast.

The sight was simply too much for Robert to behold. His body started to tremble as it was overcome with orgasmic spasms. His hand squeezed the trigger one more time.

As Amanda was hit with the beam, she felt like she was consumed by an inner fire. Her body renewed it's expansion with a vengeance. This time the muscle growth's pace overstepped everything else, Amanda grew a little taller to 6'6" but it was her musculature that defied description. Her veinous network developed itself first, pencil-thick blood vessels drew themselves across her skin. It seemed like a magical serum was being pumped through the new veins, they throbbed new growth throughout Amanda's body. Her legs grew to be bigger around than her brother's waist, her waist had not grown larger, but her relaxed six-pack had etched itself so deep that it was like she had softballs in her tummy. Each of her ass cheeks became so firm that the demarcations between different heads of the muscle were visible. Her shoulders grew broad and defined, each the size of a cantaloupe. Her arms inflated up to larger than 20" around, bigger than her old or current waist. Her breasts had ballooned up to the size of volleyballs. The enhanced sensations in her breasts and clitoris finally overcame her senses, an orgasmic tsunami overcame Amanda as she fell back onto her bed in a satisfied heap.
