Lucy has always been a keen horse rider, the bonus for me is that when ever she rides she is horny as hell after. She is in her late 30's and trim with small firm tits, shapely, muscular legs and a nice bum. I don't ride but will go and watch her and help out. Last year she bought a new saddle and after its first use was randier than ever. She explained that there was a small ridge on it which rubbed her pussy and clitty and that she had cum from just the movement as she rode. A few days later I was at the stables when she returned looking flushed and a with a noticeable wet patch on her jodphurs. She quickly dismounted, tied up her horse and pulled me into an empty stable. She couldn't wait until we got home, pushed her jodphurs down, bent over a bale of straw and told me to fuck her. Her cunt was absolutely dripping with juices, gaping wide open, as she stroked her clit and held herself open as I slid my cock in her. She hadn't taken my full length before she gasped she was cumming and I felt her cunt spasm, gripping my prick as I shafted her. I pulled out then set up a steady rhythm as her fingers attended to her swollen clitoris until she went rigid as she orgasmed again and I spurted my seed into her fuck hole. Fortunately there was no one else around and we quickly dressed and after sorting out the horse went home to clean up before a more leisurely fuck. After that first time, I fucked her several times in the stable if it was quiet. Lucy told me that if I wasn't there she was so desperate for a fuck she would go in the barn, lay on a straw bale and masturbate before coming home. The long cold winter put a stop to our activities and we had to wait until getting home to fuck. With the warm weather returning at last we had our first stable fuck a couple of weeks ago. With the continued good weather Lucy took a few days off knowing it would be quiet in the yard during the week. When she got home we had some great sex and she told me she'd wanked in the barn after riding. On the third day I got home and she told me something had happened. She explained that she had stripped naked and was laid on the straw, playing with her erect nipples and using the rounded end of her riding crop on her self, slipping several inches of the crop in her pussy and rubbing it against her clit, fucking her cunt, when she realised that she was being watched by Richard, another rider. He had his prick in his hand wanking and she'd been so aroused she called him closer and had sucked on his cock before letting him fuck her. As she told me my cock was soon hard and I pushed her on the bed, undressing her. I pulled her panties down, the gusset was soaked in cum and as I spread her legs her cunt opened, spunk dribbled out running down to her arse. What a horny, slutty sight. Another mans cock had spunked in my wife's cunt. I got between her thighs and buried my face in her pussy, licking and sucking her cunt clean then up to her mouth for her to taste the fluids as my prick entered her used hole, fucking her hard until she came, begging me to shoot my load into her cunt. Afterwards she explained that she'd be so ready for a good hard cock she couldn't help it but it wouldn't happen again, then with a knowing smile added "Unless you want me to". I was getting hard at the thought of her letting another bloke fuck her and told her it was OK but that next time I wanted to see her being taken and would enjoy watching as she was fucked. "Good" she said "Richard's going to be there again tomorrow. Take the afternoon off and hide in the upper part of the barn. He's sure to want to fuck me again". The next afternoon I hid and heard them returning from the ride. A short while after Lucy came into the barn and lay a blanket over some straw, saw I was there as she undressed then lay on the blanket with her legs spread wide, stroking her pussy when she was joined by Richard and then, to my surprise, another bloke Alan. She was going to let them both fuck her as I watched. They both undressed and stood stroking there pricks watching Lucy fingering her sloppy pussy until she turned over offering her soaking cunt for Richard to fuck, telling Alan to get where she could suck his cock. I had a clear view, seeing that Richards cock was a good 8 or 9 inches (something she hadn't mentioned) and almost as thick as Lucy's wrist. Standing behind her he rubbed his huge, hard cock along her slit, then held her hips as he rested the helmet against her cunt and pushed it in to her. She gasped as his cock penetrated her tight cunt, her pussy stretching to accommodate his prick. He mouth was open, panting, as she took his length and Alan grabbed hold of her head pushing his cock in her mouth to suck. Slurping on his cock, grunting as she was fucked, his body slapping against her bum as he gave her cunt a hard shafting ramming his cock in and out as she tried to keep the other cock in her mouth. I quietly moved and was stroking my cock watching Lucy's cunt stretched tight and being pounded. Her cunt was soaked with her juices lubricating his large cock which she was now easily taking to the hilt as she started to shake and shudder, her back arching when her first orgasm hit her. She was having difficulty keeping Alans prick in her mouth and said something to them both. Richard slipped his cock from her and took her place on the straw. Lucy got on top of him, then gripping his cock held him and guided him back into her cunt moaning as he spread her again, his slippery prick sliding easily in her pink cunt hole. He was soon pumping her cunt again as she lay back against him giving me a clear view of her cunt being fucked. Her tits were being pinched and pulled by Richard as he thrust his prick in her. Then I heard her say "Alan, I want your cock in me too". What a dirty slut, both together, my prick getting even harder at the thought of seeing her DP'd. He got between her legs as she managed to slip a couple of fingers in, pulling her cunt open wider. Moving so Richards prick was still just inside her she told Alan to push his cock in as well. He slid his cock up her as she lowered herself down Richards pole, both cocks disappearing into her fuck hole, probably opening her wider even than when I fist her. I fingers were flashing over her clit, as she frantically frigged her self, calling out "Fuck me harder you dirty bastards. Fill my slut cunt with your cocks. Give me all your spunk you fuckers. Make me cum. Cum in me, cum in me". Alan slammed his prick in her, fucking her roughly as she demanded to be fucked harder. Her body was glistening with perspiration, as she forced her cunt down hard on their pricks as she came, their cocks twitching as they pumped spunk deep inside her cunt. She lay back, Alan's prick sliding out of her then she lifted herself off Richard. She sat legs together watching them dress before they kissed her and I heard them drive off. I was down with her and had my cock into to her still stretched cunt, fucking her, feeling their sperm running out round my prick as she pulled my lips to her mouth kissing me, whispering that she loved me, her elastic cunt muscles starting to grip my cock as we fucked. I only lasted a couple of minutes before I felt Lucy cumming again and I shot my cum inside her. Sliding down between her legs I licked her clean, sucking cum in my mouth before kissing her opened mouthed so we could both taste and swallow spunk and her love juices. She is going to tell them that I know that they have both been fucking her. Next time I will join in and she wants all her holes filled and is hoping to take Richards thick cock up the ass whilst Alan and I fuck her.
