Give her your stamp of approval.

A few days later, Gemma brings in your morning mail: the usual stack of envelopes, but one small package. You know what today is. Stamp day. You open the package, revealing a custom stamp. Its bold design is unmistakable, a thick mahogany handle and authoritative font: "Property of Scott". The accompanying ink pad is a deep, dark crimson. Good for over ten thousand stamps. Gemma hasn't noticed yet. She's too busy sorting the mail. You watch as she sorts through the mail, her movements efficient, her focus absolute. When the last envelope is in its proper pile, you tap your finger on the desk to get her attention.

"Skirt up. Panties down," you instruct.

She obeys, her cheeks flushing as she hikes the fabric of her skirt to her waist and slides her panties to her knees. You gesture for her to bend over your desk, her ass bare and exposed, and she does so, her skirt riding up. You stand, the stamp heavy in your hand. The sound of the pad thudding against the desk is loud as you punch the stamp into the ink pad. Then with a swift chop, you stamp down on the soft curve of her right cheek, the stamp pressing into her skin with a sharp thud. She yelps as the ink brands her. The mark is perfect - a deep red rectangle, with crisp and clear letters against her skin. Gemmashivers but doesn't move, staying perfectly still, waiting for your next command.

"Good girl," you say, even though she doesn't need the praise. The stamp is reward enough. "Off you go."

You send her off to attend to the client emails. By mid-morning, they're drafted, proofread, and ready to send. You beckon her over with a crook of your finger. This time, she doesn't wait for instructions. She lifts her skirt, her panties already pooled at her ankles. She bends over, hands flat on the desk, her ass presented to you like an offering. She shivers as the cold metal of the stamp slaps into her skin, this time on her right cheek, mirroring the first. The symmetry is perfect, the marks now framing her ass like a work of art. A bruise-like mark forms, her skin darkening where the ink has seeped in. She stands, smoothing her skirt, and continues with her duties.
