Knotty couple with a knotty past

Ny wife and I are recovering drug and ** addicts.
We have been clean for 8 years now and have a happy family. Our ** life is amazing and we have a bunch of fun toys. I always have to restrain her hands, not just because we like **; but I have to keep her hands away from me doing some very bad things to her **. This way I can make her ** so hard she passes out. While she's unconscious her body continues to move and convulse from the intensity.
What we use to get her to have multiple back to back ** intense enough to make her black out are inflatable dog knot **. I have three different sizes from an orange size knot and is 6.5 inches and grows too about 8 inches. The biggest is 9 inches and grows to 11 inches maybe more.
The girth of the whole thing grows too and the knot is the size of a softball. We got these off Amazon for a very reasonable price. I get turned on by stretching her to the max and making her ** like crazy. We aren't new to her taking knots but we have only had these toys for about a year. We had pretty vanilla ** for years because we were both working through recovery from substances and really ** ** that people have when they are using high powered stimulants and staying up having ** for hours at a time days on end because we only did drugs and had **. It was a pretty sad existence tbh. However the ** was out of this world and we learned some things that we would have never learned. My roommate went on vacation for two weeks and I watched the Man’s Best Friend. He was super sweet and a real stud. My now wife and I were twisting a puddle in a bubble if anyone knows what I mean. We were taking a break from ** cause honestly I couldn’t keep up anymore. My now wife can be a Real ** when she was high and **. This sweet buddy flashed his ** some and we joked about it. It was maybe 6 inches but relatively smaller girth. It wasn’t a joke for much longer and we had our first experience of her taking a ** that wasn’t mine. We were both turned on and after a few attempts of him trying to out his ** in her hole he finally got it in. He pushed his hips deep forward as he slid inside her she screamed he’s big as he pounded her hard from behind. I wasn’t sure what I was watching but I could tell he was getting bigger because she was going crazy. He buried his bone and my wife kept moaning he’s huge and it kinda hurts. We both never expected that his ** was stuck inside her and she couldn’t get it out. She panicked some but shortly accepted that she was stuck there til he was done. She said that his whole ** was throbbing and she could feel ** getting pumped inside her. It was hot and the ** was a hotter temperature like he had a fever. She came over and over again having full body convulsions. He finally pulled out and this ** was like nothing I had ever seen. She looked at it and couldn’t believe how something so large was able to fit inside her. She made the point of saying it was much bigger when he was locked inside her **. We did really think about anything before and never expected this outcome so we didn’t even consider condoms or anything. Which was funny because we never used them so we didn’t have any if we wanted to use them lol. We googled what a cream pie could from him would do. It turned out we were safe and since we can call him Bernard, he’s a Saint so no chance of her getting pregnant or anything crazy like that. She took a quick shower before coming back to bed. I was so turned on I had to have my fun too. This kind of activity became some what common over three years with different buddies or ours. We had over a hundred different knot tying sessions with 14 very satisfied Studs of **. We even had a partner while she was pregnant with our first child. When she got pregnant again we knew we Had to get clean and change our lives so we could be good parents. We both went through treatment and therapy for substance and ** addiction. We did what we had to and worked on our selves and our relationship. This is why our ** life was limited and basic for years. We started spicing our bedroom time up and we are more in love than ever. The toys we use are amazing and she gets off like crazy but I can tell her body misses the real deal. She about ** the whole knot ** inside her when she is getting off just like she would milk a big peace of meat for all the **. Basically the throbbing knot gets stuck at the entrance of her ** and fills up her whole G spot as there is 8 or more inches of summer sausage size meat for a shaft on the softball at the base. His hard throbs and pumps of hot ** deep inside her filling her up triggers her to ** more and more. Her ** squeeze down like a vice on his ** stuck inside and the more she squeezes the bigger he gets and he ** even more in her **. This goes back and forth until she’s loaded full. That is what her body is trying to do but the toy doesn’t shoot fresh hot **. We can put synthetic ** in this toy and pump it inside of her but it’s just not the same. I can just tell. we have both talked about what we are doing and love that it’s just us two with some toys that do what we like to do most. We are healthy and both of us are very satisfied. However I’m confused after something happened earlier this evening and now I am awake at 3 in the morning writing a long ** confession about what has been keeping me awake all night. My wife and I were sitting on our porch when a neighbor who lives in our building a few doors down had his Mans best friend with him. He is a very muscular Bully Type, that are also total sweethearts. He came up to my wife to say hello and get attention. Her and I look down and there is a pretty thick and long ** slipping out by the ground. Neither of us acknowledged it but we both know the other one saw it too. I don’t want to bring it up because I’m kinda scared. This could be a trauma trigger or upset her which is the last thing I want to do. I can’t help it but I am thinking about her ** up, face down having some warm ** instead of inflatable knot toys slowly pushed into her **. Her arms tied behind her back and laying on our wedge. Her having to stay put as she is getting pounded like a jackhammer taking it deeper and deeper. I want her to ** as it swells up to full size in her **.
