I was invited to a Halloween party through a mutual friend and got sick from drinking too much. No one seemed to notice me go up to barf and after I finished I ducked in one of the bedrooms to rest. I crawled under the bed and was surprised by a couple coming in the room whispering. I was mortified wondering what I should do as I hardly knew any one at the party. I could see the couple through the Art Deco mirror that was attached to a vanity. I recognised the woman as one of the hosts about 50ish and dressed as a fairy costum. I guess it was. And the young guy was 20 something dressed in a Cavilers outfit.I wasn't horny at that time but that was soon to change. They were sitting on the bed getting all heated up when a smaller bald wimpy guy came in and locked the door behind him. I later found out it was her husband. He assured them all was safe. No I didn't have a good shot at them all the time but this is what happened. He sat on the vanity bench just out of the way as I could see the couple going at it hot & heavy. After awhile they got up to strip and the old guy went sraight for his cock putting it in his mouth. She was out of range but she took off her top & panties leaving he net stockings and heels on looking at them. I saw the dudes dick go from limp to hard and she walked over and put her hand on hubbies head coaxing him to suck as her young lover humped in & out. He then started to kiss her passionatly. The young one sat on the bed and she sat on his cock looking foward.. I couldn't see this but I did see hubby get on his knees licking & sucking them both. My dick was now feeling the effects. The fucking couple were moving & moaning and I'm sure the bitch lifted her ass so her old man could get it as to the way they moved. She then pushed her hubby up to get on the bed and the youngun whose dick was really huge now mounted her and was piston fucking her when they both exploded. I mean so loud that I got panicky. The dude dressed & went downstairs and the old man got on the bed and cleaned her hole. She came again and he got on top and fucked her. He came fast. They shut the door & lights and joined the party. I went down stairs out the door & drove home as I had taken my own car.I went home to jerk my cock silly at what I had witnessed. When I told my buddy, not in detail he just said I kind of heard they were strange. Hmmm
