Jason, having made up bid mind to drink, moved next to his horse and put his face to the water to get a drink.
With his face near the water, he pushed himself forwards until his lips made contact with the surface.then he took a hearty drink. He stayed their for a while, thirstier than he thought, with more and more pond water going down his throat.
When he pulled back, he had water running down both sides of his face, but he looked happy and satisfied. He looked around and admired the nature all around him. There were green trees on all sides of the pond except on the part he was. That was where the trail he had been riding went by, and that part was covered in grass. Getting sleepy all of a sudden, he decided to pull himself up to a lone tree by the side of the trail, and rest his eyes for a minute. His horse would wander around and graze the grass; he wasn't too worried about it.
Ten minutes later Jason awoke with a start. His horse was nearby, face down in the grass. Not spooked in the slightest. What had woken him was a strong rushing of blood feeling to his crotch. It was like morning wood, but a lot stronger. At first he just noticed it with detached interest. Then it became too much for him to bear and he began touching himself.
Initially he undid his pants button and reached both hands into his pants to feel himself. One went to his balls and the other to his penis. While his one hand slowly massaged his balls, the other felt around his cock to make sure everything was alright. He felt alright, just really horny. With that taken care of, he starting to stroke himself. It wasn't much for him though. His hand and penis were both so dry, and he wanted something better. Sexually aroused to an extreme state but with nothing to release himself, he looked around, frustrated.
His thoughts drifted to his horse and he realized that there was a possibility of release related to that. He looked around for it and spotted it grazing about fifteen feet from him. It's muscular butt was to him, and every time it's tail swayed to a side he saw it's thick droopy black vagina and large anus.
With the state he was in his horse was certainly tempting. He was mesmerized by the shape of it's butt and couldn't help himself from staring at it's meaty vagina. He licked his lips and stood up, never taking his eyes off the horse.with slow but sure steps he approached the backside of the horse. His penis was making a huge tent in his pants and he found the strain to be uncomfortable but for the time being had his focus elsewhere.
When he was right behind the horse he placed a hand on each butt cheek and leaned in. He was a few inches away from the horses vagina at this point. The horse didn't even register that it noticed and kept on eating. His eyes were glued to the horses pussy and he brought himself even closer, stopping when he was an inch away to stop and smell it. It smelled like urine and sweat but there was also a highly musky smell. It was like a girl had went to high intensity spin class and never showered afterwards.
Jason licked his lips and leaned even closer still so that his nose was in the horses anus and his mouth was on its pussy lips. He opened his mouth slowly and breathed, tasting the aroma. He could eat that for dinner but he had more important matters to attend to. He moved his tongue out enough to make contact. The horse still didn't seem to care. With his eyes closed he started to lick the outside of the horses lips, all the while breathing in her strong musky, earthy scent through his nose, which was inside her anus almost. His penis was throbbing very strongly and he felt free as he let go of his inhibitions and started to really get into eating out his mare. He had his eyes closed still and his mouth open wide, with his tongue out all the way. He ran it up and down both sides then up the middle, going further at the top to lick over the horses anus. On his way back down he reached over with a hand and prayed the now slick flesh, revealing the pink inside. He licked over the inside of the horse's vagina then proceeded to tongue fuck her actual hole for a little bit. This continued for about five minutes. After he was satisfied with his work he had a dumb smile on his face and he stepped back to admire his work. The horse's pussy was indeed very wet now. It still grazed the grass, although started to look back at him now and then, but still didn't think of him as a mate.
Jason didn't really care what it thought and was going to do what he was about to do anyways. He looked around for something to stand on so that he could service the horse properly. There was a log in the woods that worked so he pulled it over to the horse back end and put it there in the ground. The next thing to happen was his pants came off. He went about it ina reasonable fashion and soon stood there naked from the waste down, with a very erect and hard penis. He stroked himself a little and giggled at what he was about to do. He put one foot on the log then the other and hoisted himself up. Flailing around for a second on the unstable footing before grabbing the horse tail for support. With the tail in his hand he pulled it to the side. then he grabbed his cock in one hand and starting slowly rubbing it up and down the middle of the horse's vagina until it split open. He continued to do so until his head was good and wet, then placed it at the horse's entrance and pushed in. He was immediately met with the feeling of wetness warmth and pleasure he had been missing, though it was a bit spacious since he didn't have a horse's penis. With his desire for a vagina to push into he thruster back and forth into the horses black vagina until he came a minute later.
