Serena lounged on the living room couch in nothing but an oversized shirt that barely covered her ass, legs spread just enough to tease. Carl, her brother's best friend, had been left alone with her for the weekend while her brother was away. She noticed the way his eyes kept drifting to her thighs and decided it was time to start breaking him in.

"Come here, Carl," she said, patting the spot beside her. When he sat down nervously, she swung one leg over his lap and straddled him. "You've been staring at me all night. Don't pretend you haven't thought about this." Her hand slid down between them and squeezed his cock through his pants. He gasped, trying to protest, but she kissed him hard, biting his lower lip until he stopped resisting.
