Enough

Viv makes a quiet noise somewhere between a moan and a whimper. "Nuh... nuht... real..." she manages as she clenches her eyes shut and makes a fist out of the hand she uses to lean against the wall. Maybe she needs more convincing?

Your tongue is as stiff as you can make it, but her entrance is too tight to go very deep. If you could only get her to relax a bit. Without removing your tongue from her, you get out of the chair and place the QEBP in it so you have both hands free. The new position allows you to press down harder, and your chin gets buried in her pussy. You then grasp each cheek again and continue your massage, trying not to pinch where you marked her with your teeth. At the same time, you start making little circles with your tongue, pressing against the walls of her tight opening. The unfamiliar motions are making your jaw ache, but you keep at it, determined to get deeper.

The combined efforts of your hands and tongue are starting to have an effect. You can see, but not feel, Viv pushing her butt back in rhythm with your ministrations. She doesn't seem aware, and she's keeping up a litany of mumbles that are beginning to sound more and more like the soft moans of a wet dream. Her tongue is lazily touching her upper lip between words and eyelids are not so much clenched shut as fluttering. Her asshole is beginning to give, and your tongue sinks a few millimeters deeper. Emboldened by your success you start moving your head back and forth just a tiny bit, tongue fucking her from behind with your tongue and chin. Viv's mouth opens just enough for an almost inaudible gasp. "Nuht... loser... just... fkin... gudam...". She welcomes you in a little more, and you thrust your head harder and faster, willing yourself deeper. You've lost your rhythm with your hands, and now just blindly grope her heavenly ass meat, using it as handles to pull your face in further.

A pitiful whimper escapes Viv's lips, her ass clenches for a short moment, and you feel your chin grow wetter. Did she just come? An ex of yours was mini-orgasmic, and if Viv is...

A feeling of intense, primal lust rips through your body. You've been teasing for long enough, you want to fuck Ms Holdenbuch, and you want it now. You want her to remember this, you want all of her future fucks to pale compared to what you're going to do, you want to ruin all other dicks for her permanently, you want her to wake up in the mornings with messy panties thinking about that one brutal fuck in the executive bathroom that ruined her career.

You pull out your tongue from her wet asshole, your mind racing with ideas about how to finish this
