Dennis has had enough

"EWW!" Lauren yelped, jumping back. "How dare you poke me with you're little micro penis!! Now give me those clothes!"

"THAT'S IT!" Dennis yelled, so angrily that Lauren flinched back. Then he grabbed her and spun her around, pushing her at the wall. Lauren stumbled, falling out of the shorts as she caught the sink with both hands to avoid falling. She began to rise but Dennis planted a hand in the small of her back and forced her back down.

"W... what are you doing?" Lauren asked, looking over her shoulder.

"Teaching you a lesson!" Dennis said, raising his hand back.

"No no no, don't you dare..."

SMACK!

Dennis slammed his hand into Lauren's butt, causing her to yelp and thrust forward. Before she could react he did it again.

SMACK!

then again

SMACK!
