Kirsten, clad in a sheer nightie, sneaks into her stepbrother's room, her heart pounding with lust. She watches him sleep, her eyes lingering on the bulge in his boxers. Unable to resist, she gently takes his cock in her hand, feeling it harden at her touch. He stirs, catching her in the act, but she's undeterred. She strokes him, feeling his length throb, before taking him in her mouth, her own pussy aching for his touch. Their secret tryst is interrupted by a noise, leaving them panting and desperate for more.
