Her step brother

Lauren bolted up as she head someone. Her bother walked into the living room. Instantly Lauren sprung up, grabbing a pillow and pressing it over her crotch, hunching over and standing facing away with wide eyes.

"Woah, what' up with you?" Dennis asked, turning on his video game console.

"Nothing!" Lauren snapped, eyes bugging out. Her step brother shook his head at her strange behavior and went towards the couch.

"No, don't sit there!" Lauren objected urgently.

"Lauren, let your brother watch TV." Her mother said, obviously annoyed as she went to the kitchen to start breakfast.

"No... I... um..." Lauren tried to stop him, but her step brother ignored her and threw aside the blankets. He stopped when he saw the large wet spot on the couch.

"What is this?" Dennis asked. Then his nose wrinkled, catching the smell.

"Did you... pee yourself?!" Dennis asked Lauren incredulously.
