My widowed MIL was in her early 70's but still had a fabulous figure. She kept herself fit with tennis and Pilates so her legs were still shapely and a trim body. She had a bit of a belly like most women her age but her huge tits offset the big of fat she carried around her midsection. She looked like an older Kris Jenner with lighter hair and bigger tits. 

I had taken to doing work for her around the house so I could try to get giimpses of her tits or ass, as she often wore tight clothing or short skirts and shorts. I'd almost always take a bathroom break where I could sneek into her laundry room and grab a pair of recently worn panties to jerk off into. 

One day I was going to her place to do some yard work in the backyard. She had said she may be out so to just go through her gate at the side of the house into they yard if she wasn't home. When I pulled up to her house I notice a black Cadillac Escalade parked in her driveway. I didn't recognize the car so thought it may have been one of her rich church or tennis friends who was over for tea. 

I walked down the side of her house to the backyard and let myself in. Her house was desgined with her bedroom on the main floor and had patio doors that opened up to the yard. I could see one of the doors was open and heard voices coming from her room. Something told me to be quiet so I snuck up to the side of the door and poked my head around to see who was there. What I saw blew my mind. 

My church going MIL was on her knees in front of a younger black guy going to town over his 10" cock. She certainly knew her way around a cock as she sucked his black rod. She held it up by the tip with one hand, as she played with is ass with the other. She licked the shaft up and down then made her way down to his large balls and took one in her mouth. 

She was naked and wearing a pair of her high heels so I finally got a good look at those marvelous tits. I was so turned on I unzipped my pants as I watched the pair. They were too busy with each other to notice anything else but I still stayed as quiet as I could. 

A couple of minutes after sucking his balls he grabbed her head with both hands and shoved his cock into her mouth. He began fucking her mouth violently which she seemed to enjoyed. One hand was pulling at her nipples while her other hand reached down to her moist cunt as she fingered herself in time with his thrusts into her mouth.
