Katie uses her tongue

Katie pushed her tongue forward through her 'o' shaped lips.

She felt the warmth of Samantha's pussy as her tongue entered. She moved her tongue upwards and retracted it back into her mouth

"DID I TELL YOU TO STOP!?" Samantha thunderous voice yelled at her.

Katie immediately went to full speed, her tongue moving even faster. She could hear the giggles from school mates who were standing a mere couple feet around her, continuing their conversation

"What about her tits?" a female said.

Katie didn't think she had big tits, in fact she had one of the smallest in the class, why did it matter so much anyway?

"No no no. Look at that ass," one of the males suggested.

You heard the whistle blow signally that half time would be over within a few mintues.
