Jane has had a high sex drive ever since I’ve known her. Even 7 years after we married we fuck almost every day. She'll suck my cock, swallowing my spunk, is happy to experiment, fucking in different positions, outdoors if we get the opportunity. A couple of years ago she suggested trying anal, which she now loves, using a douche first, then taking my lubricated cock in her arse and a dildo in her cunt. She is 34, a year younger than me, 5' 6” tall, slim, great legs washboard flat stomach and after a boob job last year 38 inch double D tits. Sometimes she shaves her pussy completely but usually has a brazilian just leaving a narrow strip of almost black pubes which I prefer. After seven years I suppose it was only natural for us to start thinking about having other partners, finding other ways of spicing up our sex lives. We both liked the idea of being watched fucking or watching the other having sex. Jane has an exhibitionist streak, dressing in short skirts, going out with out any panties and wearing low cut tops, with no bra after having her tits done. We go to a shopping centre she will wear a short skirt, travelling up the escalators, me several steps lower watching as blokes look up her skirt at her naked cunt. Often she will stand on the upper walkways next to the glass, so anyone below can see up her skirt. Sometimes if she's feeling really dirty she will go to the toilets for a wank then join me for coffee in a street cafe. Crossing and uncrossing her long legs, sitting with her cunt visible, wet and open as if she's just been fucked. After a day like that we don't usually get home before having to stop and fuck. It's a real turn on, pulled in to a lay by with both doors open on the side away from the road, Jane bent half inside the car, hands resting on the seat while I fuck her from behind with cars speeding passed a few feet away. We’d arranged to meet at lunch time in the summer, being a work day, Jane was wearing a knee length summer dress, but before leaving the office had slipped her panties off. I was waiting in the park and we found a shady area to sit. Sitting on the grass with her knees up, but together, the dress rode high leaving her legs uncovered almost to her pussy. We sat drinking from bottles of water, my hand resting on her thigh, almost at the fold by her cunt. With her knees up from certain angles it was possible for anyone to see her naked bum and part of her pussy gash. It was quiet, we'd been there about 10 minutes when Jane pointed out a bloke who was passing for the third time, pretending not to look at her. He was smartly dressed in a suit, aged around fifty, greying hair, about 6 foot. Jane said “If he comes back and there's no one else about I'm going to flash my gash. See what he does”. “Run a mile” I suggested. Sure enough, a few minutes later, back he came. Jane and I pretended to be engrossed in each other and not to have noticed him. He was about 10 yards away, my hand still on her thigh when I felt her part her legs. He wouldn't see any thing until directly in front, so I leaned over kissing her, moving my hand to her pussy and pushing her legs open wider. Not that they needed much pushing, one knee almost on the ground her cunt exposed as I slipped a couple of fingers inside her and rubbed her clit with my thumb. She could see over my shoulder and whispered that he had stopped and was watching which made her wetter. Jane was getting really aroused, pressing her pussy against my fingers, telling me the man had his hand in his pocket stroking his prick. She took me by surprise when she called to him to come closer and when he was next to us suggesting he got his cock out and have a wank. He looked around, even I thought that was a bit risky but Jane had other ideas, getting up indicating a hedge, trees and some large shrubs saying we could do it there. We were well screened and she took off her dress, unclasped her bra revealing her huge tits for him, standing naked in a park in the centre of town at lunch time. She stood, letting him get a good look, teased her nipples until they were hard, reaching between her legs she played with her pussy, masturbating in front of a stranger, telling him to get his cock out, before going over to him. She got down took hold of his prick, then moving in closer slid his cock between her tits pressing them around his member and told him to tit fuck her, sticking her tongue out licking his knob with each thrust. He stood there looking down at her, moving faster until with a groan he shot his spunk splashing her face and tits. There was still no one around, I'd got my cock out, moving to take his place, for a blow job, but instead she stopped me and said “Not that, no one can see. Fuck me”. She lent against a tree and I entered her from behind. Sliding in to her soaking pussy, feeling her fingers frigging her clitoris as we fucked while the bloke watched. I had one of her tits in my hand teasing the nipple, her breathing getting faster, her cunt clamping in spasms on my cock as I thrust in her knowing she was close to orgasm, then her panting as she came, the point when she likes to feel my spunk splattering in her cunt, 2 or 3 more strokes and I came, shooting several jets of spunk deep inside her. I pulled out, and fetched her dress, bra and bag as she remained leaning against the trunk, legs spread, cunt gaping open, spunk running out, forming strings dangling between her legs dripping to the ground. She reached down with her fingers and pushed them inside scooping more cum out, collecting a large dollop, lifting her fingers to her mouth and licking them clean. Having got most of my spunk she did the same with the drops still on her tits. She asked for her bag, wiping her face and tits with some tissues, found her panties and put them on, then her bra and dress. The bloke politely thanked her, then to her surprise gave her twenty pounds and walked off. We had a good laugh about it walking back to her office. That night we had a great fuck talking about what we'd done but that was just the beginning.
