Now for the first time I looked past the animal's shaggy head.
Yes, Brute's cock was hard as a rock!
"Oh, Brute," I sighed, "your prick is so big. I never knew you could… could get it up like that."
Hunching over from my sitting-up position, I reached down either side of his hairy ribs and automatically grabbed his stiff dick. It throbbed in my fingers like his heart was stuck in his balls.
Back and forth I began stroking, jacking Brute off while he continued to lick my twat with his tongue. Already I was beginning to think about shifting positions so he could actually fuck me.
However, before I could make the maneuver, my design was short-circuited. Brute's hard-on jumped in my hands and the knobby tip abruptly erupted. I had beat his meat too vigorously and he was coming in a sticky torrent.
Dog-cum drenched my bare tits, dripping from the tips of my erect nipples. A thick rivulet passed between my breasts and dribbled down my tummy until it filled my navel and whitely blotched the dark bloom of my pubic bush.
I stood up and walked away, trying to calm myself down by taking a series of deep breaths. Anxiety was torturing me because I was afraid I'd blown it by milking Brute's nuts too soon. His dick was probably as limp as a noodle.
Finally I could stand the suspense no longer, and I whirled around to face my canine lover. To my delighted astonishment, his cock was as long and hard as ever, even as it still dripped with the last of the cum it had just spurted.
And Brute was wagging his tail as incessantly as ever, "I'm ready to fuck you," he seemed to be saying with his subsequent chorus of barks.
Powered by some animalistic impulse raging within me, I got down on all fours. Yes, I was behaving just like a bitch in heat. I could even smell my randy, barn-yard scent.
"Fuck me, Brute, fuck me!"
Jumping on my back, the huge dog sank his claws into my bare skin and took hold. Then, powered by his sinewy flanks, he slammed his furry pelvis against my wide-open butt. His sword-like cock had nowhere to cut except right into the gaping wound of my cunt.
Suddenly my fuck-hole was filled with several inches of thick dog-prick and I loved it. My hips began to move as though they were operated by an internal motor.
Farther and farther Brute penetrated until he had it all the way in. I could feel his fuzzy balls tickling maddeningly against my labia. He was fucking me to the hilt!
Once he had proved he could hump me all the way, Brute set to work pistoning the full extent of his cock back and forth in my tight cunt. The friction produced by his long strokes drove me wild.
"Faster, Brute, faster!" I implored. "Fuck me faster and faster!"
His hard-on increasingly resembled a jackhammer as he tried to keep up with my demands. My twat was being pulverized.
My orgasms were coming so rapidly that it wasn't long before they all blurred into one enormous, continuous release. I couldn't help but wonder if the bitches of his own species felt this way.
The only elements now missing was having my pussy swamped with jizz. A cuntful of creamy dog-juice would be the frosting on the cake.
"Come in me, Brute!" I screamed. "Stop holding back and fill my cunt with cum!"
Brute barked savagely. He sounded like he was on the verge of going for someone's jugular vein. However, I just attributed his fury to his ejaculation. The pressure in his balls had to be excruciating.
But when the barking didn't stop, and no flood of hot cum accompanied it, I realized that something was wrong. Perhaps we were not alone as I'd thought.
Looking up, I focused my eyes. For the first time in several minutes I concentrated on my surroundings.
Grass was parting about a hundred yards in the distance. Actually I could hear it more than I could see it, but it was definitely happening.
Somebody was coming. Brute had been warning me.
Now, with his stiff cock still cemented within my cunt, the big dog turned mean. Growling and snapping, he was psyching himself up to attack whoever was intruding on us.
Then, when he tried to get free of me, he couldn't. A dog's hard-on has a sort of mechanism on it to keep it inside a bitch's fuck-hole when he's screwing. Nature wants to make sure all the jizz gets to the female's ovaries, so a knotty lump automatically rises about a third of the way down the male's tool. It keeps him locked in place in order to assure conception.
This canine phenomenon was happening right now to Brute. The more he tried to struggle free of my pussy, the greater the pressure was against his cock. In trying to end our love making to respond to the danger, he was increasing our fucking motion.
And, meanwhile, the intruder was drawing nearer and nearer. At this rate, whoever it was would come into view just at about the moment Brute couldn't hold back any longer. There'd probably be a witness at the peak of my degradation, with an animal's fresh spunk overflowing from my snatch and dribbling down my legs.
Now the sounds were so close I could make them out. The most noticeable one was a clomp, clomp, clomp.
But if it was a horse, who was the rider? The only person I knew with a horse was Susan, and she was still supposed to be in school.
Or was she?
Suddenly I noticed the position of the sun. To my surprise it was blazing in the Western part of the sky. It was much later in the afternoon than I had calculated. School was out.
Brute's growling abruptly stopped. Apparently he was satisfied that we weren't in danger. Brute's tail began to wag.
"Brute, is that you?" came a familiar voice.
I looked up just in time to see Susan leading Firestreak through the parting green wave of the meadow. She was as naked as a jaybird. I didn't have time to wonder why.
Frantic about my daughter finding me in such a degrading situation, I struggled to get free of Brute's lancing cock. However, his hard-on was trapped in my cunt, and throbbing more intensely by the second.
All of a sudden there was a pelvic lurch from Brute. His huge dick actually expanded an extra inch up my snatch and I knew I had lost the struggle. My daughter would soon come upon me with the humiliation of fresh dog-cum washing down my thighs.
"Brute!" Susan called again, and then she was upon us.
Just at this point, the head of Brute's cock exploded, fragmenting into a million liquid chunks. He was coming like a firehose inside my pussy.
"Oh my God!" Susan shrieked when she saw us. However, contrary to my expectations, there was no anger or disgust in her voice. In fact, in a moment she was laughing.
"S-Susan," I stammered. "I… I can explain everything."
"Wow, here we come looking for a nice, secluded spot in the meadow to get it on, Firestreak, and run into Mom beating us to it with old Brute."
"What?" I blurted incredulously, unable to believe my ears.
"Why do you think I'm not wearing any clothes?" Susan turned her attention to me. "Firestreak loves to fuck me after school. And I love getting it from his great, big cock."
"Why didn't you tell me?" I asked, hurt that she had kept something from me.
"Believe it or not," she chuckled, "I thought you wouldn't understand. But, tell me Mother, how come you didn't tell me about Brute?"
"It's the first time," I answered defensively. "We went for a walk and it just happened."
"If you say so, Mom," Susan smiled indulgently. "But you don't have to be uptight about it with me."
"Are you really-really going to fuck your horse?" Somehow I knew this afternoon in the meadow was far from over.
"Sure," she replied without batting an eyelash. "Want to watch?"
I dumbly nodded my head. Although I was aghast, I realized there was no turning back. If having sex with her palomino pony was part of my beloved daughter's life, then I'd just have to accept it. I certainly didn't want her thinking it was dirty and going behind my back.
"Mom, I'm so glad you approve," Susan smiled warmly, as she came over to Brute and me and took a good look at his cock engorging my leaking pussy. "Mmmmm, looks like you had a pretty good time yourself."
