She gives in but it’s already too late

Lauren’s anger died down as she stood to her feet, whimpering as she realized her great mistake as not only had she just confirmed to everyone that she was a big baby but also got her sister peeved making her humiliation so much worse. As she stood up, Vanessa grabbed her arm and pulled her to a bench. She draped Lauren over her lap and ripped the diaper off of her. “W-wait,” Lauren said. “V-vanessa, please, please don’t. Wait, I’m sorry!”

“Oh no you don’t. You’re the one who decided to throw a tantrum and use potty words, so now you get a spanking,” Vanessa said. “Just like the naughty little girl you are. And we’ll do this until I think you’ve learned your lesson.”

SMACK. Lauren squealed as Vanessa had no mercy as she spanked her bare bottom. The spanks came quick and hard and Lauren did everything in her power to not cry and whimper. “I-I’m sorry, Vanessa, please. Please stop.”
