The stepsister's hunger for her stepbrother's cock is insatiable. She finds him napping, his tired dick soft in his pants. She unzips him, pulling out his flaccid member and gently sucking it to life. He stirs, but she's relentless, her head bobbing up and down as she takes him deeper. His cock hardens, stretching her mouth, but she's eager, her saliva coating his shaft as she works him over. She can feel him swelling, ready to burst, and she opens wide, ready to catch every drop of his pent-up cum.
