K9 Tips for Mature Wives

© 2025 by Bumpkin Keith

My wife has been fucking our dog for nearly 2 years. She loves it. She loves his size. She loves his speed. She loves his force. And most of all she loves his cum volume. But if you had met her just a few years ago you’d have never predicted this. She was a virgin when we married and inexperienced. She was not overly adventurous in the bedroom. For example, She had no interest in trying anal even though her pussy was too big for me (or my cock was too small as I now understand). However she did enjoy blowjobs and sucking down my cum load whenever she could. She obviously had a fetish for cum. She also obviously needed a bigger cock to stretch her pussy. I had asked her about another man, but she did not show any interest in swinging or taking in a bull. I knew that a dog could provide the size and cum volume that she liked.

I’d always wanted to see my wife get mounted by a dog. I realised that it would be a slim prospect, but I wouldn’t know unless I tried. I purchased a Great Dane pup for her as a guard dog. After the children all left the family home, my wife would be home alone for days at a time whilst I was away working. He quickly grew to full size. He had massive balls which no doubt held a lot of cum. My wife formed a close bond with him and he slept in the house. As he matured I began to train him for sex. The best tip that I can give to anyone trying this is to get a pair of your wife’s dirty panties and let him sniff them as you are wanking him and making him cum. My plan was working. I noticed that he’d focus on my wife’s groin, more so when she was ovulating or on her period. I took her bloody pads for him to sniff also. She turned away when he’d stick his nose into her pussy, but after several months it did not bother her that much. He had a huge cock, about twice the size of mine. It would extend when he became aroused. My wife got a good look at it and she was obviously impressed and curious also.

I noticed that her pussy would occasionally be very wet when I returned home from work. I’d fuck her that evening before she showered. It was around this time that I came home early one day. I was purposely quiet. As I entered the hallway I could hear my wife talking. She was saying “good boy, good boy”. I waiting and eavesdropping for a short time before it became obvious that she was knotted with him in our bedroom. Rather than blow her secret, I backed out of the house before reentering. I yelled out as I entered the front door to make my presence known. I heard panicked noises in the bedroom as my wife rushed to get dressed.

She came down shortly after wearing a t-shirt and panties. She was looking slightly distressed. Our GD followed her out. His cock was fully extended and hanging down with his knot exposed. His shaft was twitching as he spirted cum on the wooden floor.

After kissing my wife I turned our attention to our Great Dane’s huge cock. Small pools of cum were developing on the floor. I said something like “That’s a waste. You should ready take care of that.”

My wife looked shocked and embarrassed. She knew that she had been busted. I reassured her that I was fine with it. It took her a while to believe me but I kept reassuring her. I asked her if she wanted to suck his cock. She sheepishly nodded her head to indicate that she did. I took hold of the base of his shaft and pointed it backwards. He began squirting again. My wife knelt down and began sucking the tip. She took over holding the shaft whilst she enjoyed swallowing his cum. I positioned myself behind her. I pulled her panties to the side with one hand. They were soaking wet. I separated her labia with my fingers. My cock was semi-hard already watching her suck his cock but the view of her pussy made me rock hard. I could see a large amount of doggy cum pooled deep within her gaping pussy. I quickly got behind her and took hold of her hips. I slid my cock into her sleek cum filled pussy and I began pounding her hard. I was soon cumming and adding my small load to her big cunt. I kissed her with satisfaction. Her mouth was full of doggy cum which tasted great. I went back to her pussy and gave it a good cleanup. I licked out as much dog cum as I could. It tasted fantastic. This is when my wife understood that I was perfectly happy with her new kink.

She is usually mounted once a day in the evenings. They remain knotted for 5-20 minutes. I then lick her clean.

She lies back with her legs spread and encourages me to try and get it all. She informs me that most of it is too deep for me to access. She has compared our cock sizes by holding them side by side. She enjoys reminding me of the size difference. He is twice the size of me and he has a massive knot. I also enjoy these comparisons, especially when she is using his cum for lubricant as she strokes me. I try and fuck her hard, and I cum quickly, but most of the time she can hardly feel me. I realise that I have been cucked by my dog, but I am happy that my wife now enjoys a bigger cock.
