She knocks gently on the door before pushing it open, her heart pounding in her chest. “Daddy, are you busy?” she asks softly, peeking her head inside.

Her stepfather looks up from his desk, a surprised smile spreading across his face. “Well hello there, princess. What brings you to my office?”

She steps inside, closing the door behind her. “I just wanted to come thank you, daddy. I know you’ve been helping mom so much lately and I really appreciate it.”

Her stepfather leans back in his chair, eyeing her appreciatively. “Oh is that so? And what exactly are you thanking me for?”

She takes another step forward, her hands twisting nervously in front of her. “For everything ... for being such a good husband to mom and taking care of us.”

He stands up from his desk, walking towards her with a predatory gleam in his eye. “Is that all you’re thanking me for, sweetheart?”

She shakes her head, backing up until she hits the door. “No, I mean ... I want to thank you properly.” She turns around and slowly hikes up her short skirt, revealing her bare ass to him.

“Fuck, you naughty girl,” he growls, coming up behind her and delivering a sharp spank to her ass. “Did I tell you to go around showing your ass to strangers?”

She gasps, arching her back. “No daddy, I’m sorry! But you said I’ve been a good girl, right? Even with mistakes...” She looks at him over her shoulder pleadingly.

He smirks, delivering another stinging slap to her ass before running his fingers over her slit. “Indeed I did ... naughty girl.” He pushes a finger up her ass and she cries out, clamping down on him. He continues to rub her sensitive spot until she’s trembling and mewling with pleasure.
