My friend Sally had been including me in threesome sex with her hubby Bill for over 4 months. My hubby wasn't giving me sex and was away with work a lot. So I managed to meet with Bill and Sally at their home usually twice a week, leaving each time with 3 or 4 deposits of Bill's sperm inside my vagina. I'd had a cervical cap inserted so Bill could cum inside me. He had already got Sally pregnant but we continued to have sex together. They were becoming more daring, screwing outdoors, in the sea or in a forest. Fast, hard fucking, semi naked, until both Sally and I had Bill's sperm inside us, before returning to the car with his spunk oozing down our thighs under our skirts. I felt so sexy and excited in my short skirt, not wearing underwear so Bill could fuck me without removing clothes. I was initially nervous but after doing it several times, I relaxed and even loved the thought that just maybe someone had watched us getting fucked by Bill.

Then one night after work, I called round and instead of staying in, they were getting ready to head out. We grabbed some chips and burgers on the way and Bill pulled into a car park so we could eat them. The car park was deserted and dimly lit. It was in the middle of nowhere, out of town and deep in the countryside. After eating, Bill started undressing Sally, removing her bra and sucking her nipples. I was in the back seat and removed my panties. I fingered myself under my skirt and became quite damp as I watched. I was quite excited at the prospect of getting screwed in the back of their car - having sex in a car was something I'd never done before. Sally started to undress Bill and went down on him, getting him hard and erect within several minutes. He eventually climbed naked into the back seat and began to undress me, sucking my already erect and hard nipples while Sally licked his balls and anus, putting her front seat-back down so she could reach his sexy bits. Soon I was naked and Bill got on top, pushing my legs back so my feet touched the roof of the car. He pressed me firmly into the back seat as he rammed into me. I screamed and grabbed hold of his buttocks as his cock plunged deep into my vagina, then he began to fuck me. It was undoubtedly the hardest penetration I'd ever experienced up to that time. Sally was reaching over to squeeze my tits as Bill humped me. It was so exciting, I'd never been screwed in a car by my hubby so this was a first for me. Bill was so deep inside me and his vigorous thrusts caused his cock to bang into my cervix every time. It was a little sore at first but when I came very hard within seconds, the pain subsided! I just hoped the cap would remain intact to protect my womb from eager sperm.

Suddenly, a car pulled into the car park. I couldn't see how close it was but got quite a shock when a guy peered through the side window and began watching Bill fucking me. Sally beckoned him to the front passenger door and to my utter shock, duly opened it. The guy already had his cock out and was wanking as he watched. It looked quite big, maybe even bigger than Bill's 8+ inches but it didn't have the girth that Bill's cock possessed. He cupped Sally's tits and she began to take him in her mouth. He moaned pleasurably. Meanwhile, Bill's excitement was growing and he was really giving it to me. I reached a violent orgasm and screamed as Bill continued to fuck me. The guy reached back with one hand and began fondling my breasts. Bill leaned forward and opened the back door. The guy moved round and pushed his cock into my mouth. Both men were fucking me - Bill in my pussy, the stranger in my mouth and throat. Sally had got out of the car and was taking the guys trousers and pants off completely. She began to suck his big balls, lick his anus and bite his bum. Within a few minutes the guy let out a loud groan and a torrent of spunk shot into my mouth. He pulled out and sprayed the rest of his sizeable cumshot over my breasts as Bill kept fucking me. The guy yanked his cock several times to keep himself hard. He closed the door and moved towards Sally. I watched Sally step out of her dress and pull down her black lace knickers. She was naked, bar the stockings and suspenders she was wearing and the guy's mouth dropped open at the sight of her neat bush. I watched him disappear from view, no doubt fixed between Sally's legs and tasting her wet fanny judging by her moans.

A few minutes later he reappeared, pressing Sally against the door and kissing her passionately. Then Sally asked him if he would like to fuck her in front of her husband. I watched him excitedly lift Sally up against the side of the door and plunge his cock into her. She cried out loudly and the guy groaned, telling her he was going the give her a "real good fucking". He pinned her against the door and began fucking her. Both Bill and I had an amazing view of his cock pounding into her. The guy had large low hung balls which bounced wildly as he fucked hard, with Sally's ass pressed firmly against the glass just above my head. She had clasped her legs around his waist, digging her ankles into his buttocks and was holding on around his neck as he pounded into her, pushing his face into her wobbling tits. I could hear Sally screaming loudly on climaxing several times and after about 10 minutes or so, the guy also began groaning, telling Sally he needed to cum and asking her if she wanted it in her mouth or over her tits. To my surprise Sally screamed for him to cum inside her, telling him it was ok as she was already pregnant and that she wanted her husband see him fill her womb with his sperm. The guy was shocked and shouted "REALLY!" Sally confirmed and begged him to cum in her pussy. The guy asked if her husband would be annoyed and Sally said "no, he's fucking my best friend in the back seat and will soon be putting his sperm in her!" The guy became very excited and told Sally that he'd always wanted to shoot his sperm into another's wife. Sally told him to shut up and urged him to just do it, saying she wanted to feel his cock explode inside her. Bill became so excited and was fucking me like a demon. I became noisy with the total banging he was giving me. Seconds later the guy banged Sally hard against the window as his cock and balls throbbed hard. Sally climaxed and the guy let out loud moans, telling her he was going to fill her womb completely with his sperm. She cried out as he came hard inside her, urging him to pump her full of his seed. He banged her against the window a second time and his buttocks tensed. He held her quivering body firmly against the window and I could see his balls expanding and contracting as they pumped his seed into her. Eventually some of his spunk began leaking out of Sally and running down the glass. She cried continuously and clamped her legs around him until he had finished flooding her vagina with his sperm. Bill was loving this and his excitement was borne out in the way he finished me off - within a minute of Sally getting the stranger's spunk in her, Bill released a huge torrent of hotness deep in my vagina, bringing me to a powerful orgasm. I can honestly say it was the biggest load I've ever taken inside me. My body spasmed hard but Bill held me steady, his weight fully pressed down on me until he'd finished putting his sperm up me. His cock was so deep inside me that it squeezed against my cervix as it flooded my pussy with spunk. I thought it would never end and I screamed several times as powerful spurts blasted the depths of my vagina. Like Sally with the stranger, I cried to Bill not to stop and to fuck me completely. As Bill shot his load in me, Sally was cleaning the stranger, licking his cock and tasting his salty cum. Both Sally and I were completely spent but I couldn't believe Sally had let a complete stranger put his sperm into her. It was the first time I'd seen her being shared, fucked and spunked by another man in front of her husband (who was of course fucking and spunking me). And Bill loved it of course!!

When the guy lifted her off his cock, loads of spunk poured out of her swollen pussy. He got dressed and asked Sally if he could keep her knickers. She told me later the gusset was damp with her own sex juices after Bill had been working her breasts. So the guy was wanting her panties to sniff her sex and as a trophy to remind him of the wife he'd fucked and spunked in front of her husband. Sally handed him both her knickers and the bra then slipped her dress back over her naked body. The guys spunk had created a trail down both thighs, staining her stockings. So she peeled them off, drying her pussy with them, then unhooking the suspenders before handing the lot to the guy. Meanwhile excess cum from Bill was leaking heavily from my reddened, swollen pussy, staining the back seat. My thick fire crotch was soaked in a mixture of Bill's sticky cum and my sex juices. I quickly dried it with my knickers, then dried my tits and mouth where the guy had cum over me, before slipping them on to mop up Bill's excess semen and finished dressing. We went home but oh what a sexy experience it was! And we would be back to that car park on a later evening!
