Tues 9am kids at school and both of us off work..... She puts on a full black body stocking and red thong and bra. Covers it all with a dress down to her knees and high heels. We drive towards the motorway and she unbuttons my jeans and takes my cock between her hands.... She's playing with me and leans over to kiss my erect throbbing cock.... She starts to suck it and her knees and ass are on the seat as passers by see her ass shaking out the window. We join the motorway and pull up besides a truck... He sees her ass and stays besides the car. She waves at him and spreads her legs showing her stockings and red thong... He wants more so she signals to pull over at the next junction. He follows us to the layby and pops his head by her window. She's rubbing her wet clit with one hand and playing with my cock as he reaches in and squeezes her ample breasts. He invites us to the cab. We follow and he allows her to go first.... Ogling at her legs and under garment. I follow then he joins us. He opens the bed and she lays down with legs wide open. Showing her neatly trimmed Brazilian and parts her lips for me to lick.... As I bury my head between her legs I hear an unzipping sound.... As I look up she's stroking his thick cock and making it erect.... Its bigger than mine.... She puts my head between her legs again and forces me to lick her wet moist juicy and tasty pussy. As I get some air I see she's now teasing his cock with both hands and he's sucking her plump and erect nipples. I start to pump my erect cock into her moist pussy as she tugs him harder.... I can feel her getting more moist and he reaches over and starts to lick her pussy as I'm fucking her. I feel his tongue on my cock and balls and it feels good ..... First bi experience.... I don't know why but I take my cock out and he starts to suck me and licks all her cum and juices. She's enjoying the view and starts to watch and continues to rub his cock harder. I feel myself Cumming.. Some pre cum he devours and I can't control it as I cum and shudder in to his mouth he swallows it all without wasting a drop.... He looks at me satisfied and I am in shock at what's happened.... She sits him between us and put my hand on his cock. First cock I've ever played with. We both stroke hard and feel the throbbing getting more intense.... He spurts all over the cab and licks it off as much as he can. The drive back was silent.... As we approached home she says..... Next time, you'll have to suck a cock! I secretly smile and hope.....
