It was a couple weeks ago and like most weekends I was at Master's for the weekend and after preparing Master's breakfast I was sucking his cock as he ate. Many mornings one or two of Master's neighbors would come over for coffee as I was caring for Master's needs and I had gotten used to them watching me. They are all Master's friends and married so at times Master will allow me to suck their cock which i actually enjoy because I know it makes Master happy. This morning how ever no one came over and Master told me He told them we were going out so not to come over. Master told me they were calling for a nice summer day he thought we'd take his old car out for a ride, it's really a nice car, he said it's a 1972 Chevy Impala convertible which he restored to original condition. Sometimes Master will take it, and me to a antique car show to show it off and everyone seems to like it but Master said today we were just going for a ride up along the coast. Once Master finished his breakfast we went in and I climbed into the shower with him to get him washed for the day. Usually Master will let me suck his cock then turn me around to use my bum before we get out of the shower but on this day he didn't. I thought it was a little strange but knew not to question it and soon after I had him all dried off, shaved and dressed for the day. Once I had finished Master took my hand and lead me into his room to pick out what I would wear for our day out. He chose a one piece dress, it was very light and when there was a strong light behind me became almost see through. It was kept closed with snaps up and down the front and just long enough to cover my bum and pussy which Master said is long enough. As I was closing my dress Master removed my collar saying I wouldn't need it and reminding me that he had a spare collar and leash in his car if needed. Master then told me to go get a pair of sandals and as I was putting them on He pulled my hair back into a ponytail and off we went. I really like when Master takes his old car, it's so nice and where it was already near ninety degrees as soon as Master pulled out of the garage he stopped and put the roof down. As we drove Master told me it was just going to be a nice relaxing day and we'd just drive up to Maine along the coast and enjoy the hot day. Soon after we were on the highway and Master told me to take off my dress, it was a little weird knowing that where the top was down anyone could see me but I did as I was told and took it off. Master just looked at me and smiled saying I was such a good lil cunt asking me if that was cooler and I said it was and we just talked as he drove. Occasionally as a big truck passed us I knew that they could see me as they'd beep their horns, sometimes driving along side of us for a little while looking at me. Each time they did Master would look at me and smile as I knew he loved showing me off. Master was always nice when we were in public making sure we were far enough away from home so the chances of someone seeing me that knew my dad, or me, was slim. After a while Master grabbed me sliding me over close to him and he reached into the glove box taking out a bag he had in there and set the bag between his legs. Master then told me to lay on my side and as I did he reached into the bag and took out one of my bum toys. He showed it to me and slipped it between my legs and over my pussy to make it slippery then pushed it deep inside my bum telling me to sit up once again. As I did he told me to scoot back over to my side of the car and lean against the door which I did. Master then reached over and grabbed the little control box turning on the toy as he told me to put one foot up on the seat so he could see my pussy as he drove. I knew that this meant not only could Master see but all the truck drivers would too but I did as I was told and Master smiled as he reached over and turned the toy on higher. It wasn't long after that it began affecting me as my nipples got hard and stuck out for all to see and my pussy became soaked and began to swell open allowing my happy button to poke out. When Master saw my happy button poking out he smiled and said he knew what I needed as he reached into the bag once again. This time he pulled out a very long, very thick cock shaped toy handing it to me saying to use it as he drove. As I grabbed it my hand could barely fit around it and my finger tips could just touch as they wrapped around the toy and I didn't even think it would fit in. When Master told me to have fun I didn't even care who saw me because the toy in my bum was driving me crazy and I opened my legs even wider and began sliding the huge toy into my pussy. The toy was so long I couldn't fit it all and being a super bright neon orange in color there was no way to hide what I was doing and within seconds we had a truck on either side of us watching me. Soon I didn't care who saw me, all I could think of was the happiness I was feeling in my bum and pussy as I played with my toy. It didn't take long before my whole body started shaking as I orgasmed and even before I could recover I hear Master tell me to keep going. I don't know how many times I went off but soon I couldn't even move and just laid there with the toy deep inside my pussy happily buzzing away for anyone driving by to see as my body shook each time another orgasm swept through me. I remember Master reaching over once again grabbing the little control box for the toy in my bum and he smiled as I felt the vibration getting stronger and stronger. I heard him say that's full now as yet another orgasm exploded that was so strong my bum lifted high in the air, it was so strong that even with the thick toy in my pussy my juices still managed to spray out around it sending it all over Master. The next thing I knew was I was out of the car laying in the grass on my tummy with my bum high in the air and I quickly felt the toys had been removed. As my mind cleared slightly I felt the familiar feel of Master's cock pounding into my pussy as he held me in place by my hips, it was about then that I got the feeling we weren't alone and I looked up I saw seven or eight men standing there watching. I had to get up on my hands to make sure of what I was seeing but as I did I saw they were all naked and very "happy" as they gently stroked their cocks as they watch master pounding my pussy. Soon after Master began filling my pussy with his juice until he now softened cock slipped from my pussy and I heard him say "enjoy." Within seconds the men were no longer standing there watching but rush over almost fighting with each other until my mouth and pussy were filled with hard cock. It was so wild because as soon as one of them finished the others would be pushing and shoving each other until one of them won and filled my mouth or pussy once again. All too soon everyone had a turn, some more than one. and as the last one finished and let me go I was so weak I just fell over laying on the grass with my legs wide open for all to see. As I laid there with their juices pouring out from my over filled pussy the men were getting dressed to go as they talked with Master. I heard a few of them offer Master money for allowing them to use me but Master refused telling them it was the least he could do seeing his little show got them aroused. One of the men was so funny asking Master if he was sure and told master I was worth any amount he said because not only was my mouth and pussy magic, driving with a hard-on would of been murder and everyone started laughing as they agreed with him. One of the men, an older man told Master he was sorry to leave me in such a mess but Master just smiled and said he was prepared. With that Master walked over to the trunk of his car and opened it grabbing a bottle of water and walking over to me. Everyone seemed curious of what Master was going to do as he took the cap off the bottle then lifting one leg high in the air stuffed the open end of the bottle into my pussy then began squeezing the bottle to force the water out. Once the bottle was empty Master pulled it away allowing all the water to rush out as well as all the men's juices that was in there. I guess the men never knew about doing that as they watched closely saying now they knew why water bottle had long necks. One of the guys then said he had to get going because if he kept looking at my pretty pussy he'd end up getting it messy again and the other guys just laughed saying that was a fact. Soon after all you could hear was the sound of big trucks starting as Master came over taking my hand and helping me to my feet saying it was time to head home. My legs felt like they were made of Jello so Master helped me to the car still naked and helped me in. (continued)
