Never thought I would have our dog give me an orgasm

My Husband and I have always had a great sex life and he does try to spice it up now and then but it is mostly me who spices things up. We enjoy bondage and have pretty much done it since we have been together. I had decided about six months after we had our first house to try some self-bondage to surprise him when he came home from work, but I failed to plan ahead on a few things. I had practiced a few ties for my legs on the couch and thought that I had a pretty good plan to tie myself with my rear end on the edge of the cushions and my feet tied to each rear leg spreading me out. I really like to spread my legs wide during any play time because it seems to make my orgasms feel great. My plan was to use a simple slip loop on my wrist's that would also be tied to the back legs of couch and a blindfold over my eyes to complete the scene.
He usually had a fairly predictable coming home time when he does not have a large project going or traveling so I told him I wanted to make us a great dinner on Friday night so what time did he think he would be home so I can plan to have it ready. Everything was set and I had it all together on the couch, I was really nervous and started preparing myself a little too early. I still had about 30 minutes before he was scheduled to be home and I already had my legs and waist secured. I was sitting there imagining his reaction to finding me when he walks through the door and started playing with myself a little bit and getting a little worked up. After a few little feel good pulsations I grabbed the remote and turned the music on and then put my first wrist into the loop and pulled. I lowered my blindfold and reached over finally finding the other loop and pulled it tight. The ten or so minutes I had planned for incase he came home early were really dragging on as I laid there waiting to hear the garage door opening up, I had played with myself to much so I had a little bit of aching starting with the anticipation of him finding me. After what I figured was about twenty minutes I was just thinking to myself that I should not have finished tying myself up until I had heard the garage door going up because I could not get my wrist's out of the loops. Suddenly I felt something right on my vagina, like a breath of air or a breeze, but I had not heard anything. No garage door, no hey honey I am home, nothing. My mind was trying to figure out what was causing this when I then felt something touch my lower lips and anus area. I thought that it was my husband now that I felt a touch so I asked him if he liked his surprise but did not receive a response. The touches were very light and sort of flicking around until I heard the sound of a collar. My heart leaped all the way to my throat and I frantically started rubbing my blindfold off with my arm. I looked down and there was my little dog staring at me right over my crotch.
"Hey girl, how are you??" I said in my best nothing is wrong voice I could get out. "Go over and lie down in your bed for me". She wagged her tail and barked doing a couple of circles then sat down. Then I heard him, the other dog who is a little larger than her, coming through the kitchen to see what all the commotion was about. He walked right up next to her and looked at me wagging his tail when suddenly his tail stopped wagging and his nose went straight towards my mid section, pressing it right into my lips and clit. My heart was now beating so fast that my face had to have been practically purple because he licked and sniffed me like he had just discovered the greatest tasting thing he had ever had, I was speechless but managed to get out a loud NO and told them to both sit. He did not even waver, I think his tail wagged a little more actually as he started going at me with even more vigor with his tongue. I struggled at me wrists but I could not get my mouth anywhere near them and I just sat there looking down at him and telling him to sit without a single command being obeyed. I was really panicked now, calling myself stupid for not even thinking of this possibility but he had never really been a licker or it would have crossed my mind to put them in the basement.
I looked over at the clock and it was now twenty minutes passed when my husband was supposed to be home so my only hope was that he would not be much later. I had given up yelling at the dog because now he had his tongue working all parts of me and burying it into my vagina with numerous strokes ending on my clit, needless to say I had an orgasm building and it was not going to stop. I came hard probably from all the excitement of trying to get myself out of this predicament but the thing that was very troubling now was I could not get him to stop licking me and I was pulsating and shaking over and over. This was usually the time that my husband would stop oral on my vagina and come up and play with my nipples or roll me over and kiss my buns for a few while I recovered. But our dog was not stopping; he just kept diving into me and licking and I could not stop shaking. My legs were trembling so much that I thought for sure it would distract him, but no.
Sometime after orgasm number two I heard the garage door going up and was feeling a little relief as the dog had heard that and finally stopped licking me long enough to listen. I told him that daddy was home and go get him. Thank goodness it worked as he ran over to the door and waited for him to walk through and get some petting. I was exhausted and had pulsations still trembling through me from his onslaught of licking. My husband came through the door and started petting the dogs and putting his stuff down when the larger one turned and ran back into the living room. My husband looked over and saw me on the couch and his mouth dropped open. He walked over and said, "Well what do we have here??"
I was so torn, I did not want to tell him what had just happened but I also did not want him to start going down on me after the dog had just finished licking me for about 25 minutes. Then he started towards me with his mouth and I quickly asked him to put the dogs in another room first. He still ended up kissing me right on my clit and sucking it into his mouth. The feeling sent shockwaves through my legs and they twitched all over again. He was gone for quite a few minutes and I thought he was getting changed or something but then I saw that he had been gathering up some of his favorite toys to play with me and I started to lose it. He was so great about it as he started untying me and listening to what had happened. After a nice long shower and some dinner I did feel better. We were sitting on the couch and he asked me again how long I thought the dog had been licking me and I told him that I had two orgasms so probably about twenty minutes or longer. He then said that he wished he could of walked in on that sight. I knew his tone of voice and asked him why he thought that was such a turn on. He went on to explain that it just seems like it would be an exciting thing to watch. I was a little mad at first but then calmed down and could see how he would be turned on by it.
About two weeks later I was sitting on the couch thinking about what had happened and our conversation and I thought what the hell, it was not like the dog hurt me or anything and if it was something that my husband thought he would be turned on to see then why not let him have the fantasy. Later that evening we were sitting on the couch and I asked him what night this week he could definitely be home on time. He looked at me and asked why and I told him that he would come home to a sight that he really wanted to see, but you have to be home at the time we agree on because I could not take thirty minutes of it.
I repeated my set up and within two minutes I was being licked away at by him, I had turned the music up a little louder to drown out the sounds of my husband coming in the front door and put some things up in the opening between the kitchen and living room so he could be hidden from view better. I will not go into much detail other than I received three orgasms when my husband finally made his presence known and put the dogs in the other room. I heard his steps through the kitchen and waited for him to untie me but instead was greeted to a warm bath all over my vagina. It felt wonderful having him rinsing me off until I heard the vibrator turn on and felt it press against my already tingling clit.
I let out a shriek and asked him how the show was and he told me he was there to see all three orgasms and it was wonderful. The vibe was very quickly getting me to number four and then he started putting his cock into me while stroking my clit with the vibe. I was going over the edge and came so hard that I think I stopped breathing for a minute. He stroked himself in and out of me for a long time and finally came himself telling me I was quite a woman to let him have the fantasy.
