Erika stripped naked and pulled on her father's boxer's. She didn't want to become her father, she wanted a buffer, Hazel, between her and who she was going to become. She applied the salve.
Erika watched in the mirror. Her neck become thicker and her hair became shorter. She watched as her face becoming more angular and defined. Her nose became larger as her eyes changed from dark brown to her father's own green eyes. She felt the testosterone pumping through her body, filling her with a power that she had never noted in Nathan's body.
"Ah...fuck..." he growled in his male voice.
His chest expanded separating Hazel's breasts and then they started to deflate. Becoming pectoralis muscle, the fat in the breasts burned off like melting butler. Nipples from the size of quarters down to nothing at all. His hips expanded as his ass turned from shapely to hard muscle. Will groaned as he vagina expanded, a feeling like a surgeon screwing around with his internal organs with sedation. Will grimaced but took the pain has a small penis started to push out of his vagina. First in like a miniature dick. Then it was one inch and two and finally it reached full size.
Will looked at his body.
Hairy and toned with muscle. Will's hair was longer than Erika had remembered seeing on her father. The balls dangled off the end of a cock that was fully erect. The difference between Nathan and Will was Erika was held back by Nathan being gay. This body was straight and wanted to fuck a specific woman, Lily. This was when the lust was so strong it led to Lily falling pregnant with Erika "as soon as Will kissed me" she had joked at the time.
Memories flooded Erika's mind. Lily's favorite positions, her love of foreplay, she likes to be treated like a lady. Will found his dick engorged with blood as the veins popped out. His balls churned with cum as he went to make a baby.
Erika could feel the sex and power coming from the other room. She felt her own breasts and examined them with her hands. They were perky, her nipples were hyper sensitive, pushing in the fabric the bra cups. She loosened her bra and started playing with her nipples. Soon the other hand went into her panties and she slipped a finger in. Whatever the fuck was happening to her? What had she agreed to? Was she that desperate for a baby?
