Marissa does this almost every week...

She's one of your favorite clients, but a workaholic. It will take some effort to get her stop and relax. You stand behind her chair, and start massaging her shoulders just outside the neck, an area that's always sore with the way she sits. She sighs deeply as she continues typing. Soon her shoulders feel loose and you start to move on.

You start to unbutton her blouse from the top button and let your hands roam over her chest and stomach.

She reaches and unhooks her bra. "Ah that's so much better," she says, "that thing has been killing me all day."

Still standing behind her, you reach down and gently knead her breasts, feeling the nipples harden in your palm. You spend a few minutes teasing and pinching her nipples. Despite her attempts to focus on a document you're eliciting little gasps and she nuzzles her head against your arms. An IM notification appears on her screen, and before you notice what it says, she quickly closes her laptop, and says "Get under the desk, I want your mouth now."

She stands up and shimmies out of her black pencil skirt and panties, folding them neatly and placing them precisely on the desk. You kneel under the desk for her. She grabs her work phone so she can type up some emails and feel productive while you warm her up. She's reclined her seat all the way back and spreads her legs invitingly. Her pussy lips slowly open on their own as she does.

You kneel under the desk and kiss up and down her exposed legs, teasing her with kisses closer and closer to her pussy. With your hands you massage her thighs inward, as if gathering pleasure and focusing it in one spot.

She reaches down and grabs you by the hair, gentle but firm. She pulls your head up until your eyes meet.
"I believe I said that I want your mouth now, yes?" She nods your head for you and pulls you in.
