In the quiet of the house, the young stepsister can't resist the temptation of her brother's body any longer. She sneaks into his room, her heart pounding with anticipation. He's sleeping, but she doesn't care. She takes his cock into her mouth, her tongue exploring his length, her cheeks hollowing as she sucks. She's clumsy, but she's enthusiastic, and her brother wakes up to the sensation of her wet mouth around him. He grins, letting her continue her eager exploration.
