She's a quick learner

"Try again," you urge, pulling her head towards you again. Her mouth slides easily over your shaft, her tongue teasing and playing as she engulfs you. Her eyes look up at you as she sucks you deeper, wide and wanton and shining with moisture. When you reach the back of her throat she works her jaw, tilting her head as she tries to swallow all of you. You grunt fiercely at the sensation of being devoured, loving the submission on her pretty face.

With a sudden gulp, you pass the final barrier, sliding into her throat as her eyes widen, streaming with moisture. Tears and mascara streak her pretty cheeks as saliva drools from her lips. You hold her head, loving the feel of being buried in her tight throat, the sense of conquering of this rich young wench. Her hands press against your thighs, pleading for release as her eyes start to roll up in her head, giving evidence of her utter helplessness.

The savage reptile brain would like nothing better than to hold her face impaled until your throbbing cock explodes and fills her throat with cream. You can feel her starting to shudder, sending delicious tremors through your straining shaft. Her fingers scrabble at your thighs, helpless but frantic.

It takes an effort of will to pull her off your cock and let her breathe. She's wracked with great shuddering gasps as she looks up at you, her face smeared with tears and spit, strands of drool glistening from her lips to your cock.

"So....oh God... so deep....I've...I've never...oh God...Oh God...so deep..." she pants desperately, her hands making little fists as they grip the legs of your khakis.

"You did well," you growl, stroking her hair. "Very well." Her eyes light with pride at your praise and she moves to gobble you again.

"That's enough for now," you tell her, holding a handful of her hair. "I want more of you."

You let go of her hair and step back, nodding to her to stand up. She obeys with alacrity, her eagerness written on her pretty face.

"Do you want me to bend over your desk? So you can fuck me from behind? While I'm helpless and wriggling?" she murmurs, looking at your desk with excited anticipation as she starts to pull her skirt up.
