Krissy, the dominant stepsister, exploits her stepbrother's lust for her curvaceous body, enticing him with her pert tits and shaved pussy. She demands he watch as she touches herself, her fingers dancing over her clit and sliding into her wetness. His cock strains against his pants, but she won't let him touch it. Instead, she makes him bet that he can't resist her teasing for an hour. If he loses, he must serve her sexually. The clock ticks down as Krissy pushes her brother to his limits, her taunts and teasing nearly driving him to cheat. When the buzzer sounds, she grins wickedly, ready to claim her prize.
