Wife’s transformation 2

Those who have read my first story will know that for better or for worse, my wife has become our dog’s full-time bitch.

Those who have read my first story will know that for better or for worse, my wife has become our dog’s full-time bitch. I purchased our dog Reggie to keep Cath company whilst I was away for work. When I was at home, I’d encouraged her to be sexual with him. I had always wanted to watch a dog fuck my wife. Cath was reluctant at first, but she gradually warmed to the idea.
My fantasy came true when after much persuasion Cath allowed Reggie to have sex with her. She was immediately hooked.
We made it a regular component of our sex life. We quickly got into a routine where Reggie would fuck Cath most evenings. She couldn't wait to get down onto all-fours to allow him to mount her. She’d moan loudly as Reggie penetrated her pussy with his big cock. They would then be knotted for at least 10 minutes whilst Reggie pumped cum into Cath’s pussy. She loved being knotted. She loved feeling Reggie’s cock pulse with each shot of cum. She loved the warm feeling inside her pussy as it filled up. I would follow after Reggie. I loved the feeling of my wife’s pussy being full of dog cum. I would always cum myself.
However, Cath’s pussy became very loose. Reggie’s cock is a lot bigger than mine. He has a cock that would put 99% of men to shame. Its a BRC! The problem was exacerbated by his huge knot. Sometimes Cath and Reggie would remain knotted for 20 minutes. Cath’s pussy would be stretched to the size of a Pepsi can. I could hardly feel anything when entering her immediately after this.
Cath gradually became more distant from me sexually. She’d let Reggie fuck her once in the evening whilst I was home. She would then patiently wait for me to add my load to her cum filled pussy. But I suspected that she and Reggie were fucking several times a day whilst I was away for work. I’d return home to find Cath’s cunt, well-used and leaking dog cum.
We live on a hobby farm with plenty of space. I noticed that Cath started fucking Reggie during the day at a secluded clearing on the property. I had seen them there several times, but I had chosen not to interrupt. She had obviously taken Reggie there for privacy. They would be gone for about an hour. Cath would return as if nothing had happened. During the summer, Cath would wear a light dress with no knickers. i’d see cum running down her legs when she returned.
I reclaimed Cath from Reggie in the evenings. Cath was aware of her marital duty as my wife. She obliged me by bending over and patiently waiting for me to cum. But her pussy had become permanently stretched. She didn't moan with enjoyment like she did when Reggie was pounding her. Needless to say, she also stopped orgasm from my cock. She remained on all-fours whilst I did my best to displace as much dog cum out of her as I could. She’d be refilled with Reggie’s cum the next day, after submitting to him again. And so the cycle of cementing my inadequacy continued. Realistically, I knew that my seed did not stand a chance. Reggie’s immense volume of cum filled Cath’s pussy. His superior length also enabled him to unload his semen directory into Cath’s womb. She loves the feeling. Cath loves feeling hot cum being pumped into her pussy. A dog’s cock is perfect for this. Reggie’s cock throbs rhythmically, as he pumps cum into Cath’s pussy for the full 20 minutes that they are sometimes knotted. Cath has several orgasms during this time.
I didn't blame Cath. She was not one to fake orgasms for my benefit, and I didn't want her to start. She naturally needed a big cock to satisfy her. In hindsight, my cock was never big enough to fully satisfy her. I should be grateful that it was our dog’s cock which did, rather than another man’s. But I wanted for her to feel my cock again. I also wanted to feel some tightness again myself.
We had briefly discussed anal in the past when we had both agreed that neither of us needed it for a good sex life. But it was time to revisit this conversation. I had been thinking about anal for a while. I thought about it whenever I was fucking Cath. I’d position myself behind her. I’d look at her cavernous pussy. I’d then look at her tight brown freckle above it. I’d keep thinking about it, as I pounded away at her sloppy loose cunt. I’d still invariably get my load off inside her, but I couldn't help wondering what her ass would feel like.
Our next conversation was more promising. I told Cath that I was very happy that she had formed a close relationship with Reggie. I said that I was happy that she was enjoying sex with Reggie. She tried to dismiss it. I told her that I knew that she was bringing Reggie to the secluded clearing during the day. I had seen them. I told her that I knew that she was fucking Reggie multiple times whilst I was away. I told her that I knew that she no longer orgasmed when I was fucking her. Cath thought about it for a minute. She then realized that she has become our dog’s bitch. She was a slut who loved being filled with dog cum.
Cath started crying and said that she was sorry. She acknowledged that I was getting little pleasure from sex with her. She said that she would do anything to help. She agreed to try anal.
Cath done a bit of research on anal sex to get herself ready. She was committed to making it a success. She wore a small anal plug for a while. She kept it in whilst Reggie fucked her. I took it out and played with her anus whilst we had sex. I scooped dog cum from her pussy and used it to lubricate her anus as I played with it. She enjoyed this and started to moan as I pounded her. One night whilst having sex, I noticed that she had switched to a larger anal plug. When I asked her about it, she said that she was ready.
I took my cock and lathered it in dog cum. I then slowly pushed it into Cath’s anus. My cock went in with surprising ease. I paused a few times to allow Cath to adjust, but I was soon fully inserted. Cath tensed up and gasped a few times, but she said I felt good inside her.
I remained there for a short time to savour the moment. It felt great. I had never felt anything so tight and firm. It felt 100% better than her loose pussy. I slowly withdrew my cock. Cath moaned softly. She moaned louder as I slowly inserted my cock again. I hadn't made Cath moan since she started fucking Reggie. I took a firm grip of her hips and I began thrusting slowly. Cath moaned with each thrust and I needed to pull her back tightly, but she remained in position.
I started thrusting harder. Her ass felt amazing. It was slick and tight. I was sliding in and out with ease. Cath was moaning loudly. She slumped onto her shoulders. I had hold of her big ass. I began pounding her harder. She was moaning louder than when Reggie fucked her. I told her,
“You are a filthy slut.”
“You are just a cum dump for our dog’s big cock.”
“Your cunt is Reggies.”
“But your ass is mine.”
Cath continued to moan loudly as I ploughed her ass. I was soon cumming. I held her tight as I released my cum load into her. I could feel each pulse against her tight ass. I could feel my cum firing deep into her. I had reclaimed my wife again from our dog. My sex life was looking bright.
