Many years ago when I was still living at home with my parents, my buddies and I would lift weights out in the garage. One of my buddies, I will call him Fred (not his real name) used to joke around complementing my mom in a cute funny "Eddie Haskle" type way. Mom had a good sense of humor and would lay it on thick, pretending that he meant it and she would play flirt back with him. This went on for years us young guys got older and stronger and Mom always looked good and came around for some fun attention.
I was attending the local community collage and that took all the money I could scrounge up in those days so I rode back and forth to both work and classes on a Schwinn Varsity ten speed bike. One night after classes I came silently up the dark driveway on my trusty bicycle and the big overhead garage door was down but I could see the lights were on inside so I figured some of my buddies were lifting, I came around to the smaller side door and before I turned the knob I was surprised by what I saw through the window of the door.
My buddy "Fred" was on the bench press and my mom was straddling him as she rode up and down with Fred's cock in her cunt. Both were mostly dressed but Fred had his shorts just down enough to get his cock out and mom still had her shorts and panties around one ankle. It looked like it was a spur of the moment thing because Mom had her laundry basket just within arms reach, she probably came in to do some wash and could not resist the temptation of a sweaty muscular man alone with her in her own garage.
In such a situation I would have expected to be upset at seeing my Mom screwing with my friend but at one look I understood. Heck if I was alone with a good-looking woman and she wanted to pull down my shorts and fuck me, I would be in heaven! What would I care if she were a bit older, heck my Mom was a good-looking woman back then.
Anyway I stayed and watched for a little while I could only see the sides of their faces but I could tell they were both enjoying themselves big time. Fred was no small guy but mom seemed to shove and grind herself down on him like she wanted more cock inside her than she was getting. As the groaning became louder and faster and I knew it would soon be over, I rode way on my bike so they would be alone to finish up. I went around the block a few times just to waste time and then I returned. Fred was lifting and mom was putting clothing into the washing machine like any other night.
I hung the Schwinn on it's hook on the wall and did some sit-ups on the incline bench and everyone chatted like nothing happened. After a bit Mom went back to the house and I said to Fred that I notice that my mom looked sexy and happy that night. Fred looked like the cat that ate the canary, and I tactfully told him what I saw and that It did not bother me. Once the cat was out of the bag he went on and on telling me how great my mother was and how the muscles in her pussy could grab and pull at his cock, no woman his age has had could compare to my mom and her talent.
