My Submissive Hubby

To start, I was never into kink. Raised up country, in every sense of the word. Chores, animals, church, school, and my parents were always so against sex that I'm surprised I was ever born.
I got married at 19, and you would never know it by looking at him, but my husband is a submissive. He loves to be taken out of control and even humiliated at times.
I started to learn to enjoy it over time, and I have had a lot of fun with it. He can't get enough now, here's how it started.
Coming home from the bar one night, we called a cab to give us a ride and it was only a few miles up the road from our apartment at the time. While we were waiting for the cab I told him that if he wants to play when we got home, I was going to need to watch him jerk himself off in the cab. He replied with a "yes mam" and when the cab pulled up, he sat behind the driver and I took the door. We pulled onto the street as he was pulling out his dick and began to stroking. We were getting close to our destination when I whispered in his ear "if you don't cum, you don't get any" to which he started going faster and harder. We were turning onto our street when he painted the back of the drivers seat with his load. I was so turned on that I was happy to have him take his reward inside.
Fast forward a few months and we were parked in a parking lot of the local Walmart, and I told him I wanted him to beat himself off. He didn't hesitate, and did just that.
We had some conversations about it and he told me how much he loves when I assert myself like that, and I got to thinking.
A few months later, I talked to some friends and had them come over for dinner and some drinks. We were all having a good time, we were all getting a little tipsy, and the conversation turned sexual at some point. We started asking each other about sexual things. Our friends admitted some pretty scandalous things, and then they turned to me and asked what our kinks were.
I just smiled, looked at my husband, and he knew what I was thinking. I looked him right in the eyes, stood up and demanded that he show them what we're into. With a blushing face, he stood up, undid his belt and jeans, pulled them to his knees and began to tug his cock while I explained that he likes when I take charge.
Our friends laughed and I told them that he was going to do as he was told, and asked if they had seen enough. They all seemed to be okay with it, so I told him that he was putting on a real good show, but he couldn't disappoint.
They all sat there watching as he jerked himself and one of our friends suggested that he should cum on himself, so I told him to cover his own face like a good little shut, and he laid down on the floor. I took his legs and lifted his waist up from the floor and while he continued to milk himself. After only about a minute, he was grunting and shooting thick streams of his cum all over his own face.
The girls all laughed and called him a good slut, and I told him to sit there with us and marinade in it.
After a while, they were leaving and I thanked him for being a good sport, and I gave him a shower to clean him up and I let him have me anyway he wanted.
Since then we've had some more parties, and I have had him obey me in a bunch of places and in front of a few people, but that first time was something to remember. Maybe I'll add some more later.
Hope you enjoyed, thanks for reading. Does anyone have any suggestions on where I should have him do it next?
