Michelle and Johnny, a curious stepsister and brother, can't resist the mounting tension between them. As they're left alone, Michelle playfully teases Johnny, stripping down to her lacy bra and panties. Johnny, trying to hide his growing erection, flees to the bathroom. Michelle follows, catching him mid-masturbation. They argue, but Michelle's curiosity piqued, she asks Johnny to show her what he was doing. Johnny, hesitant but aroused, guides Michelle's hand to his stiff cock. She explores, her touch sending waves of pleasure through him. Michelle's first time continues as she takes Johnny's cock into her virgin mouth, slurping and sucking until he can't hold back. He cums all over her face, and she loves every drop.
