I walk into your office... and see you standing there, leaning against your desk, arms crossed in front of you, waiting for me. I close the door softly behind me, and walk to you. I stop when your arms unfold and your right hand reaches up to cup my left cheek. My eyes close and I sigh softly. Your thumb brushing my cheek, my head turning into your hand. Your thumb moves to brush against my lips, which are painted a deep red just for you. My lips part slightly. The tip of your thumb traces my full upper lip, back and forth, before finally sliding into my mouth. My teeth close down on your thumb, holding it there. My tongue dances on your thumb, teasing it. My mouth expertly working around your thumb while my mind races and imagines there's something else in my mouth. You know what I want, and you start to slide your thumb out of my mouth, teasing me as much as I'm teasing you. My eyes still closed, I'm imagining the look on your face as you watch your thumb slide out of my mouth - my lipstick smearing slightly, my lips full and wanting, my mouth warm and wet.
You slide your thumb back into my mouth, and I let out a low, deep whimper. Your hand is cupping my jaw now, and I can feel a slight pressure as your hand is guiding my mouth down. Lower, lower. No words spoken, yet I somehow know what it is you want. Your hand goes lower, and I'm almost forced to lower myself to my knees in front of you. My skirt bunching up a little as I do. My eyes still closed, now kneeling before you.
