My wife had asked me earlier in the week if I could stop by her mother's house and check on her kitchen sink as it had a leaky pipe and her husband was absolutely useless in more ways than you can count. I had agreed to check on it when I had a chance. I had just worked 10 hours at my work and was now on my way to Susan, my mother-in-laws house. I pulled into the driveway and parked. I walked to the door and knocked on it for a few minutes. No one answered but I knew that Susan was home as her car was in the carport.
Now let me tell you a little about Susan -- besides being my wife's mother, she is what most people consider a BBW. This is not the type of woman that I am normally attracted to. She has long red hair, an attractive face and weighs around 300 pounds with a huge ass and belly. She is abnormally small on top considering the size of her belly, hips and ass. Her tits are small at 38C cups in comparison to her huge ass. Her ass is as wide as 2 of me standing side by side, and I have a 34" waist. I don't know what it is about her that has the effect on me that it does. It might have something to do with the fact that we lived in her house for the first two years of our marriage. Anyway - back to the story.
I knocked again and still no answer. I tried the knob and it was locked. I used my key from when we lived there and let myself in. I walked into the kitchen and was about to announce myself when I heard moaning sounds coming from the master bedroom. I wondered if Susan had a male visitor as her husband wasn't able to get it up in years. (My wife told me after her mother confided in her) I was curious as hell to see who was giving her so much pleasure. I quietly slipped down the hall toward the master bedroom. The closer I got the louder the moans were as well as a new sound. The squishy sound of a pussy being repeatedly penetrated by something. A delightful sound it is too.
I continued my journey down the hall and quickly noticed that the door to Susan's room was open. As I crept closer and closer I could see Susan lying on the bed but she appeared to be all alone. With the exception on the 8" realistic looking dildo that she was sawing in and out of her red haired pussy. I was so shocked that I am surprised that I didn't make more noise and she discovered that I was watching. I knelt down and watched her as she continued to drive the dildo in and out at an-ever increasing pace.
I could not see her face because of her huge belly but I knew that she was enjoying the pleasure that the dildo was providing. It was at that moment that I realized that there was something familiar about the dildo. My wife had ordered one of those clone-a-cock kits from Adam & Eve. We played for several hours one night making and playing with the kit until we had an exact replica of my erect cock. My wife said that she wanted it for the nights when I was out of town on business. I wondered why I never seen it after that but I thought that she just kept it well hidden from our kids. I never dreamed that she would give it to her mother.
I watched as Susan drilled it in and out of her pussy. As I knelt there watching I wondered if Susan might enjoy the real thing. I could smell the strong odor of her arousal as it emanated from her room. I had to adjust my slacks as my cock swelled. I decided to go for broke and see if I could convince her to try the real thing. I quietly stripped off my dress jacket followed by my shirt, shoes socks slacks and finally my boxers. I was completely naked as I crawled into the room with my cock and balls swaying between my legs.
As I approached Susan -- I slid quietly up the bed and slowly and carefully lapped Susan's sloppy wet slit. I had to be careful not to touch her hand that she was using to drive the dildo in and out of her twat. I licked her slit for several minutes and her moaning increased but she didn't seem to realize what was happening. A few minutes later I started sucking on her engorged clit. It was like nothing that I have ever seen before. It was sticking out at least an inch or more from her outer labia. It almost looked like a mini-penis. I stared at it as I was licking her slit trying to decide if I could really bring myself to suck it as it so resembled a tiny penis. I don't consider myself to be gay as I am not really attracted to men or cocks in general -- but I had to try sucking her clit as it was so beautiful and it was calling me to suck it.
