Sit there and look pretty.

As Mr Williams sits down you strive to do exactly what you were told. You arch your spine and push out your delicious breasts, cross your ankles but not your legs, and leave your skirt up about your hips so he can see your lovely ass pressing against his hardwood desk. You smile prettily down at him and he smiles wolfishly back at you. He raises a hand and places it atop your stocking, stroking your leg through the material. This isn't doing his paperwork, but it feels nice so it's not like you're going to complain. His hand slides higher, crossing over your exposed thigh, his thumbnail trailing over the skin and making you shiver, and he enjoys the way your breasts bounce in your tight top. Then his fingers are pressing back against your damp thong and your teeth bite against your lip.

"Mr Williams..." You begin, not knowing what you're going to say.

"Hush Kiddo." He tells you, his grin growing bigger and he turns his eyes to the paper before him, his fingers continuing to play with you. "Just be nice and quiet while I work."

You take the instruction to heart, and when he looks up at you again you mime locking your lips and sliding the key down between your breasts, giving them a little shake. Mr Williams responds by sliding a finger past your thong and into your little kitty.

You gasp at the sudden intrusion. No one else has ever had any part of them inside you before, and a terrible reality of your vulnerability comes crashing down upon your airy head and makes you want to moan. But you bite your lip. Daddy told you to do what Mr Williams said. Mr Williams told you to be quiet. The last time Mr Williams told you to do anything he got your breasts out and made you suck his cock and lick your...

A second finger begins to slide in and you buck and scream into your closed mouth.

Mr Williams goes on. Just reading away while his fingers **** you with pleasure and you try and try to keep every moan and scream inside. At one point you double mover and begin to pinch your nipples and mash your breasts through your top in a **** effort to try and relieve the pleasurable agony he is inflicting on you. He clearly thinks you still look pretty as he doesn't tell you to stop.

Soon though his fingers are working you harder and harder, his thumb finding your clit and stroking and striking it to make just everything worse. You can't handle it anymore, the pressure is rising and you can't breathe for wanting to cry out. Until, at last...
