Erika's Mum was Lily. Lily was in her 40's when she had Erika. She had an older brother Nathan and an older sister Natalie or Nats. Her dad was named Eric and so she had been named Erika in his honor or something, he had left when she was three. Nats had gone to college but had left behind clothing and lingerie. Erika knew that she and their mother had both been models at various stages to pay bills or because both of them were very pretty. She pulled on a pair of pair of Nats' panties and imagined herself as a grown woman, then she pulled on the bra. Her mother and Nats were both full figured. Nats had black hair where Erika had blond hair from her mother.
She wanted to see what it was like to be an older woman like Nats with breasts and a body that the boys wanted to touch. Erika sprayed the panties and the bra with the salve. The fine white mist went through the fabric, taking the essence of Nats, and entered Erika's skin. At first she felt a bit woozy but as the salve, loaded with Nats DNA, she noticed something was off. She grabbed her head in shock as her scalp began to itch, noticing her blond hair beginning to drift in and out of her eyesight. She began to groan as pressure built up across her body, pushing her limbs and frame outwards and stretching her shirt
against her maturing chest.
She felt a mix of confusion and excitement as her muscles swelled with adolescent strength, realizing that she was rapidly growing older, but not understanding why. Her nerve centers grew more sensitive by the second as her budding sexuality was accelerated, her body twitching in confusion as her vagina became moist against the black panties. She didn’t understand the feelings surging through her aging body, but she thought that she liked them. Her nipples hardened against her shirt as the fabric moved across her chest, exciting her even more.
In a matter of minutes, she’d grown older and she couldn’t be more ecstatic. She was about to run out and show off his incredible growth spurt to her family, but a budding sensation in her chest gave her pause. She looked down in concern as she felt blood rushing to the area, leaving her chest tender and puffy as her nipples began to poke through her shirt.
Her excitement quickly gave way to fear as her metamorphosis grew more dramatic. Her breathing was speeding up as her heart rate increased, her chest pulsing alongside her cardiac rhythm. She tried taking deeper breaths to calm himself down, but with each inhale she noticed her pecs beginning to expand. She looked down in shock, unable to stop her panicked breaths as her chest inflated in a distinctly feminine way. Her budding breasts were coverable by her hands at first, but as the supple flesh filled her trembling hands, she began to realize that he wasn’t just getting older. Her groans walked the line between pain and pleasure as her increasingly busty chest took in the various sensations of her tearing shirt and massaging hands, triggering foreign pleasure zones that a young girl like her couldn’t even imagine. She reluctantly squeezed her jiggling chest, watching his new cleavage grow sizable as her shirt struggled to contain the mounds of growing flesh. With a loud rip, her new bust was exposed to the cool air of the room as his shirt was left in tatters. Only the black bra now covered her breasts. She tore his hands away from her new chest in a moment of clarity, shunning off the pleasures of her increasingly sensitive body and trying to focus on what the hell was happening to her.
“What the fuck?!” she screamed as he looked over her childish body. She covered her mouth in shock at her choice of words. She never really swore before, but it seemed she was getting older in both body and mind. She was beginning to speak like her sister. She stood up, still dizzied by her increased height, when she felt the transformative sensations trickle down her body. Her shirt, still hanging on in places, showed her midriff finished tightening up, leaving her with a curvy, athletic core from years of after-school sports. Her hips shook uncomfortably as they widened, the left side cracking out painfully before the right quickly matched its proportions. Her slender legs filled with just enough muscle to keep her athletic from lacrosse as the gap between her thighs increased, leaving her aging vagina dangling between her feminine new inner thighs. She ran her delicate new fingers through her silky hair as it tumbled down past her neck, hoping that her transformation wouldn’t go any further. His shirt was ripping as an indication that there was still a long way to go for the confused girl-teen.
“No, please, I don’t want to be a woman! I thought I was just growing older! Older girls are gross- GHAAA!” she moaned as another feminine pulse overtook him. She thrust his chest forward as her breasts grew another size larger, tearing her shirt even more. Her hips grew even wider as her legs became thicker, pressing up against her sister's panties. She felt her face beginning to tingle as it aged to match her new body, her features growing softer and more feminine as her quivering lips parted in shock.
Her pupils dilated as she felt a flood of estrogen being pumped through her body. She gasped in awe as she felt a new womb forming above her vagina, his pelvic area opening new caverns for her changing reproductive system. Memories of sex ed and parental talks she never had populated her mind as she gained intimate knowledge of female sex organs just in time for the last of her womanhood to appear.
Erika wanted to cry, but he wasn’t sure if the tears were from pain or pleasure. She was gaining the ability to bear new life and feel exclusively feminine pleasure. With a final orgasmic jolt, a new bundle of set itself at the top of his new pussy. Her freshly formed clit was already begging for stimulation, but Erika was too shocked and scared to find out if she was a woman. Instead, she looked down at his alluring body and watched her clothes continue to transform, turning shades darker as they continued to stitch themselves into something more fitting for her new body.
