Just to let you know planned events never go as planned. Grandfather came to my house to help me get ready for the dogging photo shoot in the selected costumes, He was carrying his video enabled camera I had showered and done my hair and was wearing a loose robe to not get any marks. Grandfather set his camera on a tripod and started recording saying I do not want to miss anything. 

 I started by opening my robe slowly and dancing to give him a sexy looking striptease, I said do you approve as if she needed any approval, Grandfather had bought some shimmer body lotion he said I will cover you in this to enhance your lines He smoothed it all over my body and I admit it did leave a nice looking sheen plus that was so nice him rubbing my nipples and quickly  dampening pussy lips, I said if you carry on like this we will never get there or is that the plan I guess that you would love a blow job he replied yes but you can do that later.  

He started to dress me saying you will not be used to this type of clothes starting with sheer black g string panties, black sheer holdup stockings, a thin soft black sheer bra saying this is the typical doggers underwear it will not stay on for long, he then helped me into a very short grey pleated type of school girl skirt, topped off with a school type white blouse he only fastened the bottom two buttons, finishing off the outfit was a pair of red patent stiletto heel shoes. I looked like a whore just let out of school looking for a new daddy, he said that is the perfect dogging outfit just enough to arouse any of the guys there without going totally over the top.  

Grandfather was going to be the driver there and back. I have got to admit it but being driven by him was making me feel like the slut I looked. When I sat down the skirt raised up enough to get my sheer panties fully on show with my pussy clearly on show through the thin material I felt so slutty but horny being driven by my own sugar daddy, he said I don't know about them you are going to meet but I so need you now. I would love to take you into a local bar or pub to show you off making the guys wonder what he has got that we haven't, I replied that we will put that on the list of things we need to do for each other.  

We arrived at the location and were shown where to park Ian said is your grandfather going to stay there as your cuckhold, yes, he is my sugar daddy who wants to see me pleased I think some of the others there felt a bit uncomfortable having a much older guy present consequently things were too staged and a bit wooden more of a static photo shoot rather than a flowing sex session, with guys getting into position and being told where to put their cocks all very clumsy to be honest. It turned out to be too soft and tame with no realism, it wasn't really getting anywhere so I called a holt to it. 

I was still wearing the same clothes nothing got removed so I just tidied myself up and we started off home, I said to Grandfather would you like to go for a drink at a pub it seems a shame to waste this costume, so he selected a fairly normal type of pub nothing rowdy or full of old folk, we sat down in an open booth he said you look great dressed like that but you have fastened more blouse buttons so I undid one he said better but another one will be great , This action got a few glances from other customers it felt good being looked at and I told him so, my skirt barely covered my sheer panties that were just hiding a pussy view a few guys were blatantly looking up my skirt as they slowly passed by, I said to Grandfather I am loving being on show with you in this bar .  

He said go to the toilet and take your bra off then come back and see if anyone notices the difference obviously, I obeyed him and yes it had the desired effect my nipples were now erect and hard sticking out through the thin material of the blouse with guys giving admiring glances I moved my sitting position so that my blouse was seen open from the side this had a great effect, he went to fetch another drink while at the bar a guy said is she with you he replied yes my Granddaughter  the guy said she is a sexy looking girl, he came back from the bar and said with a grin you are causing quite a stir in here you little slut. 

We had a few more drinks and I was getting hornier all the time It was great to see how just by dressing sexily you can control the guys around you, so I went to the toilet and returned to my seat I handed my Grandfather my panties and said I may as well be on full display expecting him to say something he just said good girl what took you so long, you know even if they are with their own partner they want to see it and you want to show it. Grandfather said with you looking like that I do not know how I am stopping myself from grabbing you.  

I have rescued a night from the disaster that was the photo shoot and got very horny in the process we decided to leave the pub and go home virtually as soon as Grandfather had started to drive off his hand was rubbing my soaking wet pussy I went over undid his zip and sucked his cock as we drove unusually for my Grandfather he filled my mouth with his cum after a shorter time than usual he apologised but said he was so turned on in the pub with me looking and acting as his slut, Honestly I loved it all and asked if we could do it again he replied yes I want many more nights like this.
