Frisk was sitting in her room with Chara. Toriel was in the living room reading a book. Chara thought of a plan to get Frisk in trouble and smiled to herself(I know both Frisk and Chara are gender neutral but in this instance they're both girls). She stood up and walked over to Frisk.
"Do you have any spare clothes?" she asked.
Frisk nodded. "Yes. Why?"
"These are dirty."
Frisk was about to respond but Chara stopped her as she spilled juice on herself. She sighed, knowing that she had done on purpose. She went to get spare clothes. Chara smiled and left to put her plan into action. She snuck past Toriel and took a few cookies. She then stole a few more snacks and went back to the room. She saw Frisk and smiled more.
"I brought the-what are you doing with those?" Frisk asked, pointing to the treats in Chara's hands.
Chara didn't answer, instead she shoved them into Frisk's hands and pushed her out of the door. She slammed the door and Toriel came running to see what was going on.
"What is-child what are you doing with those?" she demanded as she saw Frisk.
"Chara put these into my hand," Frisk explained.
"Impossible. She hasn't left the room."
She opened the door to see that Chara was inside. She was pretending to sleep on the bed.Toriel smiled at her, closed the door, and then turned back to Frisk.
"See," she said angrily. "She was asleep the whole time!"
"But," Frisk said nervously.
Toriled grabbed her arm and carried her to a chair. She sat down, pulled down Frisk's pants, and started spanking her. Frisk cried as she was spanked. She hadn't even done anything wrong! She tried to escape but the smacks kept coming. She felt her bottom grow hotter as more spanks were rained down. Toriel spanked harder and harder. Frisk suddenly, though she had no idea why, smiled. Toriel stopped and quickly pulled down the girl's white panties. Her red bum popped out. She then grabbed a hairbrush and proceeded to spank her with it. She continued to smile.
Toriel finally stopped after a few seconds and hugged her. She was crying and trying to hide her smile. She hugged back. Toriel pointed to a corner and she walked ovee to it. Her bum was displayed for all to see if they happened to walk by. Toriel told her to come out of it after a few minutes and she fixed her clothing. She was told to stay in her room.
She walked up to her room and glared at Chara. Chara smiled and waved.
"So you think it's funny to get me in trouble?" she asked.
"Yup," Chara replied.
"Well you're wrong." She closed the door and grabbed Chara's arm. "Let's see how you like it!"
Chara gasped as she was pulled across Frisk's lap. She felt cold air touch her butt as it was bared. She tried to get away but failed and asked for Mercy. Frisk smirked and shook her head as she smacked.Chara yelped and she smacked again. Her bottom bounced as more smacks came down. She felt her bottom became warm as Frisk continued to spank. Her bum turned pink and Frisk grabbed a hairbrush. She smacked her bottom with it and she cried.
Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack!
She stopped as her bottom became red and Chara went limp. She sobbed as she was lifted up. Frisk hugged her and Chara continued to sob. She finally calmed down and fixed her clothing.
"Will you ever get me in trouble again?" Frisk asked.
Chara didn't answer and Frisk smacked her butt and she yelped. "No."
Frisk nodded. "Good, because Sans is coming."
She gulped. "Why?"
"Oh I may have called him earlier."
The skeleton teleported into the room and floated Chara in the air. He also floated a nearby paddle. "Bare bottom right?"
Frisk nodded and Sans began spanking.
