No.

You continue pounding into her, until she's begging you for release. But you decide she can wait, you want to keep her horny. You pull out, and tell Kate you are going to finish in her mouth. She obediently gets on the floor and parts her lips. Her wet mouth enveloping your cock, makes you groan, as her tongue flicks over your shaft. You can't hold any longer, and pump her mouth full of cum. You tell her to swallow, and she does so, a few drops that missed dribbling down her chin.

"Okay get dressed and get back to work," you tell her, "I'm going to get some rest."

"But John, I..."

"You what? Oh right, I forgot," a devious thought crossing your mind, "Every half hour, you are to come in here, sit on the floor and masturbate until you are about to cum. You must stop before you do, and go back to work. Every half hour, until I tell you otherwise - that means you don't leave the building either, unless you can get back here in time. Also, please have someone bring me a new desk when I've finished with my nap."

A look of indignance flashes across Kate's face at this request, but she can only nod and walk out of your office.
