Sarah pulled off her t-short and shorts and stood at her dresser sorting for something to wear to bed. She pulled out a fresh pair of tighty-whities and t-shirt that said 'All American Boy' across the front. She pulled down the tighty-whities she was wearing and her packer-penis plopped onto the floor. She quickly scooped it up, pulled on her clean tighty-whities and plopped her packer into place.
As she looked in the mirror and adjusted it, she found herself wondering if she could keep it after the experiment ends. She found she kinda liked the heft of it between her legs.
Karyn knocked at her door, "Sarah, time for bed, son!"
Sarah quickly pulled on her t-shirt and hopped into bed. Karyn, cracked the door open a bit and peeked her head in, and smiled, "And no playing with it, young man!"
Sarah yelled out, "DAD!"
Down the hall Joseph was getting ready for bed. He pulled off his t-shirt and his shorty shorts and stood there wearing nothing but his bra and panties looking in the mirror. He wondered if Jon would give him permission to have his belly button pierced like the other girls. He then pulled off his bra and panties. His breast forms where glued securely to his chest.
Standing there naked he reached into a drawer and pulled out a tampon. Joseph unwrapped it and inserted into his prosthetic vagina the way his mom, Joseph, had showed him to do.
Joseph gave the string of his tampon a tug to make sure it was secure in his silicon girl's genitals. He kinda liked having a wearing a fake pussy. He thought he looked rather hot that way.
He quickly pulled on a pair of panties, a sports bra and a long sleep shirt with kittens on the front.
Jon knocked at the door, "Good night my sweet daughter."
"Good night, mom" Joseph answered back
With their son and daughter now in bed, Karyn and Jon could get down to other things. Jon had a new garter belt, panties and bra he was just dying to wear to turn on Karyn, and Karyn couldn't wait for Jon to see her in the new bulge enhancing men's briefs she had bought.
