Wife rides stud

Since we moved onto our 2 acres and had the house built about a year ago, we were able to aquire another 5 acres. We both wanted horses so we built a barn with stables and found a quarter horse mare to start out. Christine worked with her daily and wanted another. I ran across an old friend of mine who had a quarter horse stud he was wanting to sell so we worked out a deal.
A couple days later we went to pick him up. Christine named him Max immediately, not sure why. We got him home and introduced him to Mandy. It took a couple of days for them to adjust to each other. Christine worked with them every day.
One day I was working in the yard and looked toward the barn and noticed Christine staring into the pasture. Looking over I realized what had her attention. Max had mounted the mare and Christine was mesmerized. I walked up behind her, wrapped my arms around her and said " I want to mount you like that and fuck the shit out of you." Her reply was "What are you waiting for? Fuck me like that, fuck me hard. Shove your cock deep in my pussy. Right here." As she wiggled out of her jeans and panties she got on all fours. "Fuck me like that stud is fucking Mandy! Fuck me hard!" I shoved my rock hard cock deep in her wet juicy pussy in one thrust she was so wet. She was screaming "Yes yes yes!!! Fuck me hard! That pussy is all yours!!!" I fucked her until I couldn't hold back any longer and exploded. She had one of the biggest orgasms and passed out.
I picked her up and carried her to the stables where we had made love earlier. A bail of hay with a blanket across it was in the middle of one of stalls. I couldn't help myself, I dropped to my knees and began eating her pussy. As I licked her pussy and her asshole she began to come around. Pulling my head into her and softly moaning. I then stood and started fucking her wet pussy and raising her legs so I could suck her sexy toes. Her orgasms rolled through her one after another.
The smell of her sex is very over powering to me, and evidently to Max also. He walked into the stall, I looked down and saw his huge horse dick growing out of its sheath. It must be at least 18" long and thick. I stepped toward him and took his lead. Leading him to Christine, he nuzzled between her thighs licking her juices. Christine was startled at first. I told her "Relax baby, look at that huge horse cock. Do you want to try?" She said "It's huge, I don't think I can take it but you damn right I want to try.
I took his lead and got him to straddle her, positioning that huge cock at the perfect height for her. She took his cock in her hand, stroking it and rubbing it against her pussy. Slowly she started taking him inside her. "Damn, it's huge!!!" She was beginning to really enjoy it, taking more with every move she made. I threw a lead across his back so she could use it for leverage.
Max was beginning to thrust and Christine was countering every one. Pulling him deeper and deeper inside her. She was screaming out "oh God! He is huge!" She had about 14" of horse meat inside her. I couldn't believe I was watching my 5'3" wife with a huge horse cock deep inside her pussy. I was so turned on though, I couldn't look away.
Christine was screaming "I'm cumming I'm cumming!! He is splitting me in half!!" Max ejaculated at the same time. The force was so strong she was blown off of his cock and covered in horse cum. She layed there while I lead Max out.
She layed there "That was absolutely amazing. I had never thought of fucking a horse. I hope you still love me even though my pussy is all stretched out from that huge cock". I replied, "Of course I still love you. I enjoyed watching you take 14"s of that cock inside you. Then we made our way to the house.
She got in the shower to wash all the horse cum off of her. After her shower she walked out of the bathroom naked looking so sexy. Her gorgeous 5'3" frame got me instantly hard again. I took her in my arms kissed her deeply and said "I want to ride you like that stud does the mare. She gave me that look and turned and got on all fours on the bed. Not saying a word just shook her gorgeous round ass.
I slid my cock in her wet pussy and slipped a finger in her ass. She moaned loudly "Fuck my ass baby. Give it to me! Fuck my ass hard!!" I pulled out and slowly pushed into her tight asshole. She screamed out "Yes! Your cock feels so good in my ass! Fuck me! Fuck me! Yes! Yes! I'm cumming I'm cumming!!!!" Her body started shaking in orgasm I came at the same time. We both collapsed. She said "I have never been so full of cum, especially horse cum. I never thought of riding a horse that way.
