With each throb of her newly emerged balls xenobiotic androgens and growth hormones were being pumped by the alien dick slug into her body causing her to sweat profusely as metabolic processes went into overdrive. A sharp hunger struck her and she didn't care that a penis and a pair of balls had sprouted out of her vagina a moment ago after an alien dick slug crawled into it -- she needed to eat now and anything would do.
She dashed into the kitchen and madly scrambled for anything that could be eaten. Her sweat washing her makeup off and her once beautiful locks now in a frizzy mess as she started devouring the half-eaten meat loaf from last night with her mind intent on only one thing: consuming food to start building new structures on her body that would best suit the dick slug in its life cycle.
Looking down she could see her feet growing bigger in her socks and stretching them until a rip could be heard to reveal wide men's size 14 feet. She then watched the hairs on her toes getting thicker and darker going from thin vellus hairs to fully-developed, dark terminal hairs. This made her new dick throb and start to rise.
As those hairs spread up to her legs her legs started to bulk up with muscle as her curvy leg fat melted away into sweat. Thick muscles on her calves, quadriceps, and hamstrings ripped through her tights and hairy, muscled legs gleaming with sweat blossomed out as if emerging out of a cocoon of frail, weak femininity. As the hair spread up to her butt her once jiggly butt fat melted away as thick, hairy muscular glutes rose up to replace them.
Her new hairy, muscular ass tore the rest of her tights open and the pungent smell of man-musk entered her nose -- it was her man-musk. This woke her up and triggered her first bout of resistance against the parasite. She dropped what she was eating and in response her new balls started pumping again. By this time the xenobiotic androgens had flooded her brain and all she could think about was muscle, hair, dick, and men. She never felt so horny in her life before and she started pumping. She didn't just want to fuck those hunky, hairy men that flashed in her mind, she wanted to be them!
Her breasts got pulled further apart as her shoulders grew out and her frail arms filled with muscles, her broken arm now able to move again as her cast strained against her increasingly bulkier arms. The stench of man-musk assaulted her nose again this time coming from her armpits as thick hair grew from them, but this time it only made her more horny and she grinned as she started pumping even harder ending her first and final bout of resistance to the alien dick slug.
Next the muscles on her back started growing. Thick trapezius muscles, capped deltoids, and massive lats gave her a diamond shape as she was now stretching her blouse. The hunger struck her again and she obeyed it eager to grow and mature into one of the hunks she kept picturing as she continued stroking with one hand and gobbling everything up that she could with the other.
Her hourglass figure was gone now, washed away by the androgens and replaced with a diamond-shaped cobra back on top of thick, hairy columns of muscular legs. Her blouse finally gave in as her biceps and triceps bulked up again completely shattering her arm's cast and her shrunken sweaty breasts melted away into massive pecs that quickly filled with a layer of hair between them. Her once bountiful cleavage replaced by a hairy muscle cleavage started emitting heavy man-musk right into her face and Amy grinned in satisfaction completely lost in pleasure.
The hair that started sprouting on her toes finally reached her face as her bone structure matured. A thick 5 o'clock shadow took over her jaw as it became broader, her brow bones thickened, her nose grew, and her eyebrows got thicker with hair. By now she was so repelled by even the thought of women or being one that she already started to see herself as a man.
His dick now standing at 10 inches and soda can-sized thick the new man roared in triumph to signal the parasite's complete take over of its host. Where once stood a pretty frail woman now stood a giant, muscled, hairy man desperately looking to unload his infectious cum. The dick slug pumped one last torrent of alien androgens and growth hormones into his growing body as his 5 o'clock shadow full-developed into a beard, his scalp hair fell off leaving him bald, and his bones finalized their restructuring putting him at a height of 6'4" from his original 5'2".
With his brain flooded by the parasite's intoxicating androgens the new man could think of nothing but dominating everyone he encountered and turning them all into himbos like himself. "NO MORE BEING A WEAK BITCH!!!" The man bellowed as he pumped his dick profusely. "EVERYONE NEEDS TO FEEL THIS; EVERYONE NEEDS TO BE LIKE ME!"
"Grhh...hrrhh...GROOOOOOAAAARRRHHHHHHHH!" The new man threw his head back and roared in a deep baritone as his dick unloaded globs of thick infectious cum all over his kitchen. With the former woman's clothes torn on the floor covered in cum and food bits the newly christened himbo grinned at the thought of sharing his infectious cum and making others like him.
