my wife and i are both 39 years old and very happily married for many years.We had often talked about swinging and dogging but never taken it any further until one night not long ago when my wife had been on a girls night out and ended up back at her workmates house. She telephoned me asking for a lift home and when i picked her up about 11.30 at night it was obvious that a fair bit of wine had been consumed.As soon as she got in the car she started to rub my cock though my trousers telling me how horny she was.On the way home is a lovers lane type car park next to the beach which is popular with doggers and appears on some websites.I suggested stopping there for some fun and she was very much up for it. By the time i pulled into the car park she already had my by now very hard cock out and was bent over slowly sucking it.I pulled up to a secluded part of the car park , left the engine running , and proceeded to strip her naked while sucking her nipples and playing with her pussy.We had pushed the passenger seat fully back and lowered it as far as it would go and I was on my knees in the foot well gently licking her pussy when she whispered that somebody was outside the window.I got back up into the drivers seat and continued to suck her nipples while i played with her , by now very wet pussy.As i looked round i could see a guy of about 30 odd with his face pressed up against the window who was slowly wanking is cock as he watched us.I told my wife who shocked me by saying put on the light and let him see.I did this and she spread her legs as wide as she could while i rubbed her clit and continued to suck her very erect nipples.I could tell that she was on the edge of an enormous orgasm and while i continued to rub her clit i stood up and fed my cock into her mouth.She came almost immediately while sucking furiously on my rock hard cock.Do you want me to open the window I asked.Please she moaned and when I did the guy stuck his head in and asked if it was ok to touch.Just fingers and tongues I said and she moaned in agreement.For the next five minutes both of us rubbed our hands all over her body taking turns tweaking her nipples , rubbing her clit and sliding our fingers in and out her pussy while she came almost continually.She then got on her knees on the seat and started to suck my cock again and as i looked down on her I saw her eyes widen in surprise as the guy slipped his tongue up her pussy from behind and brought her to a huge orgasm .This was too much for me and i yelled that I was coming and shot a huge load of spunk into her mouth and over her tits.As i collapsed into my seat she turned around and grabbed the guys cock through the window and in seconds had him coming over her tits as well.I lay there rubbing two loads of come all over her tits as she had yet another gigantic orgasm as she licked the last remaining bits of his come from her fingers.We wound up the window and put out the light but not before i had noticed at least one other guy standing watching and wanking outside the car.After we pulled on our clothes we drove home where as soon as we got in i bent her over the setee and roughly fucked her from behind before withdrawing and coming all over her beautiful arse before we staggered off to bed.
