My boss has re married, jack was in his early sixties and starting to wind down in his business responsibilities, he was handing over most of the daily grind to me, not that I objected, it was just the way it was going. He had re married two years ago, Susan was in her forties, tall, slim and always well dressed. She would call in after a trip to the shops, always smeling of horny perfume and perfectly made up. Invevitably I would be aroused by her presence, she had a sexual aura that was addictive. On this particular occasion she had been in Jack's office with him for some time, I needed his signature on an important document, everyone else had long gone and I was getting really pissed off waiting, so not wanting to make too much of a scene I peeped through the keyhole to see why they were being so long. I nearly shouted out, "Jesus", Susan's cunt was being filled as she was spread over a desk, not by Jack, but by another guy, he was fucking her with long strokes, stood by her side was Jack, his cock was just visable as it dissapeared into her mouth, she was leaving wet lipstick marks on his tool as he vigoriously face fucked her. I could not believe what I was witnessing, but watched intently as the action got more vocal, clearly they were all under the impression no one was around, shifting onto my knees I managed to get a better view, she was really taking it like a pro and started to urge them both to cum on her, the guy shafting her sopping cunt pulled out and sprayed her face with thick cum, he came in buckets all over her face,neck and lips, she opened her mouth wide as Jack emptied his load straight down her throat, I have never seen so much spunk, she loved it and scooped it up with her manicured fingers, licking each in turn, she then turned her attention to the now limp cocks and licked them clean. I watched as she slid from the desk and went to a mirror, using a hankie she cleared the other globs of spunk from her neck and face and applied fresh make up. I quietly got up and moved back to my desk. Susan and Jack came out together, she was flushed and still had flecks of spunk in her hair, without batting an eyelid they both said goodnight as they walked past. I said nothing, but they must have known I had heard everything. The final person, the other guy was still in Jack's office, so I went to see who this was, zipping himself up was the elderly office cleaner, a smile on his face. As he passed me he said, " she likes older men you know, Jack's got more than he can handle there" " mind you, she is a really good fuck" There is more of this tale to tell. I was gobsmacked,
