Gratitude for Mrs Willis

This time, she did stumble and would have fallen if Isaac didn't have such a strong grip on her ass. Mrs Willis's eyes lost focus and she looked as if she had lost touch with reality. "Oooooh, oooooh ooooooh!", she wailed.

"Thank you!", said Isaac grinding his cock against her pussy through their layers of clothing. "Thank you!". With every thrust against her, he thanked her, and with every thrust she wailed incoherently. "Thank you!" repeated Isaac over and over again until his assistant was in the verge of losing consciousness because she had cum so intensely. "Thank you!" (thrust) "Thank you!". His hands gripped her ass so tightly they would probably leave bruises. "Thank you!". Isaac was delighted to watch how quickly her orgasm played out with each word he said but eventually had to release her from it and stop showing his appreciation for fear of causing her to pass out.

He quietened down and kept silently thrusting against her crotch until he was sure she was safely capable of sustaining her own balance. He released her ass, then whispered in her ear. "Suck me Barbara".

Mrs Willis dropped to her knees quickly, face still flustered and bewildered but in a hurry to comply. She scrabbled hastily at Isaac's pants and had them down around his knees when his released cock actually slapped her across the cheek. She paid it no mind and greedily opened her mouth to devour it. In moments she was in position lips around his shaft, kneeling in front of him and began to oscillate back and forth like a bird pecking at seed on his abdomen. Isaac watched his mature employee with delight, suddenly concentrated and focused on the task as her lips glided along his length and he could feel the insides of her mouth and her tongue under his cock.

In a reverse of their positions minutes earlier, the elderly woman reached up and gripped Isaac by the ass cheeks to give her greater purchase to pull her head onto his cock. She sucked and sucked beautifully and Isaac could detect no **** on the part of his employee to administer her utmost fellatio experience. He clasped the back of her head in his hands to hold himself steady, unable to stop himself and began thrusting his cock into her face. Mrs Willis made no show of complaint however, even when his cock was pushed further and further into her mouth and her face used like a pussy. Isaac marveled at how compliant she was and how devoted she was to her task, driving her fce further and further onto his cock. her nose actually pressing into his abdomen as she bottomed out, with his hole cock in her mouth and throat. The pressure was indescribable and before long Isaac felt himself ready to explode. He gave her no warning though, other than increasing the tempo at which he face-fucked her. The PA for her part gave no indication of **** and continued her own sucking and swallowing of his cock to the best of her ability.

When eventually his cum did shoot into her throat, she made no objection. If anything she redoubled her efforts to pleasure him and sucked at his cock as if trying to extract as much of his jizz from it as possible, Another thrust and more flew into her mouth and then some more. Isaac held her head tightly in his hands as he came in her mouth, then eventually began to relax and then release her once he felt he was completely done. Mrs Willis, though kept going a little longer, just to be sure the job was done and Isaac could feel her tongue darting all round his cock, making sure she managed to get the complete contents of his ejaculation before she disengaged and rocked back on her knees.

Isaac helped his assistant to her feet, watching her lick her lips and try to restore some sort of sense of order to her chaos. She made a small involuntary cough and he could see her swallow, then stood there quietly, almost at attention facing him. Out of habit, he grabbed her by the boobs once more and said "Th..." then caught himself and remembered only to thank her when he intended to cause some mischief.

"Ok. Lets try that again shall we? Can you call Bunty and see when she can come over?"

"Yes sir", she said, pushing some errant strands of hair back into place and when he released her tits she reached for her purse and got out her phone.
