"I won't do it anymore," Carol pleaded. "I promise."

Sister Rita stood up and smiled as she lifted a ruler from the desk. "You have to be punished," she said. She closed the door to the classroom and walked toward the two. "Now, lean over the desk, Carol," she said, a wicked smile on her lips.

"Please don't," Carol begged.

"Do as you're told!" she said sternly, smacking the ruler against the palm of her hand.

Carol leaned over the desk, and her school uniform hiked high on her young, trim thighs. "What are you going to do?"

Sister Rita stared at her firm, silky thighs and lifted her dress over her waist, baring her panty-clad ass. "You must be spanked," she said, lewdly looking at her tight ass.

"Oh, no! Not in front of Bob!" she whined.

Sister Rita whacked her ass with the ruler, enjoying the sound as Carol whimpered.

Bob watched, excitement building in his crotch. "Whack her good, Sister," Bob jeered. "Teach her not to be a fucking prick teaser." He rubbed his cock lewdly in front of Carol's reddened face.

Carol looked up, her eyes filled with tears, astonished at what Bob had said in front of Sister Rita.

"Be quiet, Bob," Sister Rita said as she continued to whack Carol's young ass. She stopped and rubbed Carol's ass through her panties, feeling the heat rise from her soft flesh. Slowly, she pulled her pink cotton panties down, baring her reddened asscheeks.

"Oh, no!" Carol cried. "What are you doing?" Sister Rita slowly and gently caressed the red-hot cheeks of her ass as Carol cried in embarrassment. "Your ass looks cute," she said. "I like it when it's all hot and pink!"

Carol was too stunned to say anything as she felt the Sister's hand caress her painful ass. She looked at Bob and the bulge in his pants, and wondered what was going to happen next.
