My erection was growing when she lightly moved her hand over the tip of my glans. My hands were still on my keyboard when I went fully hard and my coc...k protrude from my zipper like a rocket ready to start. She whispered: Oh I can feel your cock pulsating, do you enjoy our little game? I just nodded, she whispered: Oh maybe we should up our game a bit? She stands up and crawls under table pulling her chair towards the table so that you couldn't see her. I look around but nobody seems to have. I flexed my knees and moved my feet as she tried to get more of cock on her hot mouth. She gagged at first. Then got about half inside her mouth. She put her two small hands on my muscular ass. She gripped my ass very hard. She left two hand white hand prints on either one of my tan ass cheeks. I could feel her two big breast brush my legs.After a few minutes. I bent over to pick her up. She put her hands around my neck. She wrapped her legs around my waist. Her pussy was just above my cock.. My wife saw my raging hard cock, and continued to push her body against the stranger’s on-slaught. I heard the male’s voice for the first time and a deep heavy groan emerged as I saw his balls convulse several times, as his cock was buried deep in my wife. I imagined the stream of cum filling her pussy as I watched. My own arousal was almost too much to bear, but the sight of the stranger’s sperm pushing deep into my wife’s cunt was the hottest thing I had ever seen. My wife’s breathing slowed. Mary had lived there for a number of years, was 77 years old and very active. I was told that she was a friend of the previous maintenance guy and I noticed she drove off early ever morning. Found out later she had morning coffee at his house since he retired.My helper and I knocked on her door , standing there with tools and replacement heater. Mary opened the door, wearing a housecoat and open robe and let us in.She showed us the way to the heater closet and left us to our work. I had to send.
