Over the lap

Kevin sat on the bench, then tugged Ali by her arm onto his lap. Ali stumbled, landing face down over his legs. She moved to scramble up by Kevin put a hand on her back, holding her in place.

"What are you doing?!" Ali squealed, looking up to see dozens of people looking her way.

"Teaching you a lesson!" Kevin said. Then he raised his hand back. Ali gasped. No, he couldn't be seriously intending to...

SMACK!

His hand slammed down on her bikini clad butt, causing Ali to thrust forward. OW! That really hurt! Unfortunately, she had no time to recover as he brought his hand down on her butt once again!

SMACK!

Ali gasped. She was getting spanked, by her coworker in front of all these people!
