Later that day, Jenny came home from school and immediately pulled Jessica into her room. "Come on, Benny! I'm so horny! Nina wasn't there today!" Jessica stood in the doorway. "Me and Mom decided my new name is Jessica. Jessie and Jenny, see?" She grinned. "And... I.. um... I'm pregnant." She looked at Jenny with pleading eyes, silently begging her not to make a fuss, or accept it, or do anything.
"That's so cool! You're gonna have a baby, Jessie! Who's the daddy?" Jenny grinned up at her. "Is it Mommy? One of Daddy's friends? Come on, tell me!"
Jessica just looked at her, scared and confused. How would her little sister take it if she knew she was going to be a father? Taking a deep breath, she slowly spoke. "You are. You're the daddy, Jenny. I haven't had sex with anyone else."
Jenny's mouth dropped open, and she stared at Jessica for a long minute before shrieking in delight. "I'M GONNA BE A DADDY!!" She tackled Jessica, hugging her tightly, cock pressing up against her through the fabric of their dresses. "Thank you, Jessie, thank you thank you!" Jenny jumped up and down, grinning madly, cock bobbing up and down and waving, pulling the dress up and up in front. "We're gonna be the best mommy and daddy ever, you'll see!"
Jessica just stood there dumbly for a moment before hugging Jenny back. She took it so well, and was even happy about it... why? And a more terrifying thought... would Dad be pregnant too, soon? Jessica had no idea when a period first started, only that while she may or may not be too young, her vagina wasn't. The only thing left was to tell Dad, and to ride it out. At least now she could explain being sick in the mornings.
