I couldn't get the time off work so it was arranged for Sarah and Mal to go away for the week, on the Saturday they were leaving me and Sarah agreed to meet up early for a drink and to see each other one last time before going.
When I picked her up she was wearing a ribbed elasticated waste black pencil skirt, black stockings and black jacket buttoned up but no top underneath, apart from her black lacey cupped bra. As this was how she always dressed when we were caughting I never thought too much into it.
We went for a few drinks and then it was time for me to drop her at Mal', he had a Taxi booked to take them all the way to the coast, when we arrived the Taxi was laready there with Mal waiting inside on the back seat, we immediately go out grabbed Sarah's suitcase and popped it in the Taxi's boot, she kissed me goodbye opened the door got inside and the Taxi pulled away, she waved to me and blew a kiss.
The story is then pretty much told to me by Sarah upon her return the following week, she said that when she got in the Taxi Mal was sitting with a travel blanket over his legs as you have to remember he was 75 years old and going to the coast, he lifted the blanket up and put some of it over Sarah's legs. For about an hour they talked about the coast and Mal was remembering stories of when he was a child and going to the coast with his parents and then late wife.
A bit further on into the journey Mal placed his hand on Sarah's knee underneath the travel blanket, he squeezed it and said how excited he was about the weeks holiday, but after 30 seconds or more he started to squeeze more and then stroke her leg each time going further down underneath her black skirt eventually reaching her stocking tops, this was turning Sarah on but she was trying to keep cool as she noticed the Taxi driver occassionally staring throught his head mirror, he must have thought what is an old git like him doing with this sexy blonde 23 year old going to the seaside.
But this also turned Sarah on more, after a few minutes of stroking and rubbing the inside of her thigh he pushed her legs slightly apart so his little finger could touch and caress her black silky knickers moving down to her cunt which was by now all damp and moist with the turnon, the Taxi driver said could he pull over for a cigarette as it was still another hour or so before they arrived so they said yes, it was out in the middle of nowhere  and the layby was hidden behind trees and tall bushes. He got out and leant against his door while lighting and puffing on his cigarette, this gave Mal the opportunity to turn and put his fingers into my cunt he was fingering me with one then finally three fingers I was lifting up and with one hand touching the roof inside the Taxi, the blanket slipped down into the floorwell revealing my black skirt which was now up around my waist, Mal cupped my arse and cunt and was with his other hand rubbing his cock which I could see was erect in his trousers, Sarah said she forgot were she was for a few seconds because of being highly turned on, by which time the Taxi driver had finished his cigarette and staring at us both through the window, he opened the door and said shall we continue or do you need me to give you a few minutes more, Mal said why don't you join us it should only take a few minutes I'm about to shoot my load any minute by which time Sarah replied not until I've sucked on it you don't.
The Taxi driver was round in a shot sitting on the back seat while Sarah was sat sandwiched  in the middle cock in both hands while they both played with her tits, she then said she saddled Mal and continued jerking off the Taxi driver until both of them were coming, she got off Mal and sucked dry both of them before re-arranging their clothes and continuing on there journey, spit roat number three for Sarah she was getting more and more of a taste for it, just a shame I wasn't there.
