"Ok so you don't want me to get any older than this?" Stevie grinned.
"Are you ok with that? Not able to become a woman?" Lisa asked.
"As long as I have you, I don't mind being 13 forever." They kissed again. Stevie really liked kissing Lisa.
They cut two slices of cake, and Stevie blew out the candles. "I wish we would never get any older, but we can become younger or return to the ages we are now whenever we want!"
They ate the cake, leaving one tiny slice remaining.
Stevie shivered as she ate the cake, feeling something happen. "Well, now to try it out, I guess."
"Yeah. Ok, I'll go first. I want to be eight years old again!" Before Stevie's eyes, Lisa began to shrink, her features becoming softer, and her figure melting away. She literally shrank inside her clothing, which deflated. Her shoes fell off her feet, hitting the floor with soft thuds. Lisa slid off her chair, her jeans falling off her now skinny legs. She giggled as she kicked them off and shrugged out of her oversized shirt.
Her breasts were tiny buds, and within moments, she was as flat chested as a boy. She shrank by at least a foot in height, her panties sliding down partially, but still somehow clinging to her narrow hips, and then she was a little girl of eight, oversized socks on her feet.
"Wow, everything is so big!" Lisa exclaimed, her voice high pitched and young sounding.
Stevie crouched down and hugged her girlfriend. "Holy shit, you are the cutest thing ever!"
Lisa giggled. "You think so?"
"Yes." She kissed the little girl, who blushed cutely, looking bashful.
"I love you, Stevie."
"I love you too, Lisa. So how does it feel?"
"Weird. Good. But weird. There's kind of a disconnect. My brain says 'Man, Stevie is really cute, I want to kiss her', but my body is like 'uh..sex is icky'."
Stevie laughed. "Really? Well I guess you'll have to get older if we want to have fun tonight. So what do you feel like?"
"Cuddling and hugging?" Lisa ventured.
"This we can do." Stevie looked at the cake. "What do we do with the last piece? It might go stale."
Lisa whispered something to Stevie.
