My Grandfather sent me a text and wanted to treat me for my birthday asking me if I would like to go shopping up town for some new sexy clothes to use in our exhibitionism fun games I obviously said yes and I arranged to meet at his house, I was already feeling horny as I put on my choice of clothes for the day as a St Trinians style dress code. I.E. My hair in pigtails wearing A white blouse no bra with a loose striped tie the top three buttons undone, A grey pleated short skirt, hold up barely there stockings, red patent stiletto heels, and very unusual and not the norm for me I put on a pair of sheer black g string micro panties, that look gets you noticed when on the bus to my grandfathers with guys thinking I need to find out where that schoolgirl is from.  

I arrived and was met at my grandfather's door he let me in he said as usual you look stunning Kelly, greeting me with a kiss full on the lips and his hand up my skirt to check that my pussy is hairless   he pulled up my skirt and saying well that's a first for you wearing panties yes I admit they are very sheer and a very small G-String but I can't see them staying on for long I said I was only wearing them  because as being alone on the bus and when you get noticed up skirt by anyone at least there is a bit of cover he said I hope my friend likes them as he is very into sexy ladies just like you. 

 He said I have an old school friend called David Snowlover who travels between the USA and the UK staying with me on this visit and he wants to meet you as I have said so much about you, we have never kept things secret and are always honest and open with each other I want you to be nice to him as he is a good friend, but a typical guy who spends time in the USA be prepared for him being outspoken, He introduced me to David who was quite handsome, confident a fit looking older guy just like my grandfather, he looked me up and down and said you never said she was a model Ken, as  I sat down opposite to him his eyes were fixated looking up my skirt he said now that's a gorgeous view I can tell your shaved as the material is so sheer. Ken my GF said she is normally pantie less and not shy he said open your legs up a bit more Kelly, so I did and there I was showing my little sheer panties to a stranger. GF said David and I have always perved with young girls. 

GF said David is going to go up town for a meal and to go shopping with us to give a second opinion on my choice of clothes. When we were growing up and all through our life's he has been a very close friend and probably more close to your grandmother as we all used to go on naturist holidays together with her always choosing him to fully oil her body he always paid particular attention to her nipples and pussy lips saying we can't afford to get them burnt in the hot sun,  

We have had many a MMF sex session together there is no part of her he has not seen or touched she has always loved sucking his cock as he is quite big and always keeps it smooth. 

We caught a taxi into town GF in the front David and I in the back who obviously liked the look of my short skirt riding up who's hands frequently not so "accidently" brushed my legs and saying you would look so awesome without those panties on I replied to you will get your wish soon he said can I have your worn panties as a souvenir of meeting you. I asked do you want to take them off  me now or later he said a bit later when there are more of your juices on them as I can feel they are getting wet now I said are you always like this with young girls he replied no not all but not all girls are so sexy as you, in the way you look and act letting your GF's friend grope you I said he told me to be nice to you so if you want to look or touch that's fine maybe if you are lucky you might get to compare the BJ's from my Grandmother you have had and the Granddaughter you might get. 

We went into selected shops to buy some quite extreme clothes I had removed my panties to get the right look saying to David, I will put them back on later for you to remove them having two perverts looking and adjusting my clothes to get maximum exposure was so erotic, and those types of shops were used to it so no problems, we decided to go to a city centre pub for some lunch so I dressed C/W panties much to the disgust of my GF I sat opposite David to give him a good view up my skirt but I did not go overboard with the up skirt flashing nowhere as near as much as I would normally do I was concentrating in giving my GF old friend a full viewing of his slutty GD I was enjoying giving another fellow old pervert a decent show occasionally fidgeting and moving so that the gusset was moved to one side to expose my lips, David said to Ken my GF is Kelly usually this hot in public he said she has actually toned it down a bit for you as you are obviously an up skirt fan. 

We finished lunch did a bit more shopping and headed back home in a taxi it was rush hour so the journey took longer I was again sat in the back with David he loved to keep moving my panties to get me on show I put my hand on his trousers he was very hard so I undid them a bit and put my hand  inside his trousers his cock was big smooth and the head covered in pre cum I pulled my hand back up licking his pre cum from my fingers saying I will leave you like that as I want to lick it all from your head and to taste it all. He removed my juice covered panties putting the in his pocket continuing to play with my very wet pussy, we finally got back to my GF house David is a proper pervert he was not concerned about anyone else in the taxi so long as he was having fun. 

We went in and for GF to make us a coffee I sat down like before David said so much better pantie less your wet pussy up your skirt looks so tasty I opened my legs and said OK eat me he crawled over and started licking me not stopping when my GF bought in the coffees all he said was to David she tastes great doesn't she, he just raised his thumb in agreement GF came over removing my tie and blouse caressing my tits then got his cock out for me to suck so I was being eaten and I was sucking another horny old man, David stopped to get me naked they both stripped off and I was being ravished by the two old me in a fantastic MMF scenario both taking turns to fuck me in every hole David came in my mouth while my GF was fucking my ass he then came up from my ass for me to take his load in my mouth as I wanked his friend off, saying that they are old they certainly know how to use a girl fully. David said to my GF that brings back so many memories of us in a MMF with your wife she was always great but being honest Kelly is such a fuck hungry slut and is happy in doing everything asked of her. What a shame I am leaving you tomorrow as she would end up draining every bit of cum out of me. Can I have a few photographs to remember you by as I have your used panties so they would be a great reminder of my visit to my oldest friend, so he took a selection of photos then got my GF to take some with his cock in my mouth that also turned into a very memorable day for me too.
