Stuck Babysitting My New Sister

Ricky comes down and catches Emily Willis catching hell from their dad. She’s grounded, but she’s begging because she’s got concert tickets. Dad’s not budging—she got suspended, so she’s staying in. He turns to Ricky, says he trusts him to keep her home, then he and mom head out. The second the door shuts, Ricky asks if she’s ready to chill and watch shows. Emily flips. She’s not a kid, she can sneak out, and if he covers for her until 11:30 they both get what they want. Ricky pauses, then grins. Fine, but it’ll cost her. She drops the attitude fast and promises anything. He lays it out plain: let him fuck her and she can go. Emily’s stunned—he’s her step-brother. He shrugs, calls it ‘siblings with benefits.’ She tries everything else—flirting, pleading—but the clock’s ticking. To get to that show she strips, sinks to her knees, and swallows his cock until it’s stiff enough to ride. She climbs on, works him deep, and every grind is her bet that he’ll keep his word.
