"MOMMY!"
Sans and Frisk looked up at the scream of their daughter. Aliza ran to Frisk, burying her face in her mother's chest. The parents exchanged looks and Frisk set her crossword down.
"Aliza, what's wrong?" Frisk asked in concern. Her daughter's amber eyes were huge and filled with tears.
"I-I'm bleeding and my stomach hurts and I feel like I'm going to throw up!"
Frisk sighed, a smile appearing. "Where are you bleeding?"
Aliza could only point down to her womanhood. Sure enough, there was blood running down her leg. Frisk sighed again
"Okay, honey, you're going through your period. This-"
"It means you're the sacrifice to the elder gods."
"Sans!"
The skeleton shrugged at his bride. "What?" He asked, catching a glance at his daughter. Aliza was hyperventilating, her eyes wide. "Oh shit."
The girl screamed and ran upstairs. The two winced at the bathroom door slamming. Frisk aimed a glare at her husband before hurrying after her daughter.
