Unknown - Wild for horses

He said, "Why not? I told you I won't blow off. I just want to stick it in. I bet you don't know how good it feels. Every girl loves it."

Tanya was staring at the big piece. Jason took it completely out of his trunks now. She couldn't believe how thick and hard it was, squeezing it as hard as she could.

She had the same sensation then that she had had on the horse.

The feeling of satisfaction she had to ride with the wide back of the horse between her legs. Suddenly she wanted to feel the thick rod sticking up her.

"All right," she suddenly. "But do it quickly!"

Jason's cock was throbbing as he reached for his sister's bikini pants.

He said to her, "Lie down on your back!"

But she said, "No, like this, stick it in from behind."

She wanted to imagine she was riding a horse while he plunged it in her.

She gave him her ass, as she got on her hands and knees and he pulled her bikini pants down. She had a line where she was tan. Her back was berry brown. Her ass cheeks were china white. Her fuzzy little red muff stuck out below her pert ass cheeks. He saw the oval slit of her pink cunt and he put his penis to it. Her cunt was instantly wet at his touch.

But Tanya was scared and she whispered to him, "Remember – you promised not to shoot off!" She gripped the blanket and bit her lip.

Her brother shoved it in. It sank in half way on the first shove.

"Oh!" Tanya's cry escaped her lips involuntarily.

Nothing had prepared her for the way this would feel! Now she really had a thick beast between her legs.

She found herself squeezing and squeezing, with her thighs and with new muscles she was just discovering, deep inside her box. It felt good.

She arched her head and shoulders way down and gave him a full, high view of her ass. It gave him a perfect angle too. He slid his cock right down her wet pussy.

On the second shove, he slid it all the way in.

"Oh!" Tanya was gripping the blanket and trembling.

She imagined she was riding her horse! The big back of the horse made her spread her legs wide. She spread her knees farther apart and let her brother fuck her from behind. His big throbbing dick head imparted heat to her glowing cunt.

"Oh! Oh-oh!" Tanya cried out again. Nothing had ever felt so good before.

Jason was in an ecstasy of delight, thrusting his big tool into soft wet pussy.

He looked down at Tanya's buttocks in gratitude, and he sank his tool into her again. He grinned as he watched her youthful body strain and writhe.

"Oh! Oh! Oh! OH!" Tanya's gasps rang out in the silent forest.

Bill, shaking the last drops of his wad from his dick and strapping it back in his jeans, heard the young girl's cries. He hoped nothing was wrong.

But he was experienced enough to know that there was something fishy-sounding about those girlish gasps he heard. He strode back through the forest.

And the sight he saw when he reached the clearing smote his eyes. Although he had been half-expecting it, it was still something to be seen.

That young kid was plugging his little sister!

And the girl actually seemed to be loving it – holding her ass high up in the air like a whore, and letting him sink it in her!

He watched for a few seconds without making a move. But his cock was getting big in his leather pants again. Then he strode back over the ground between them.

The fucking couple didn't even hear him coming. They wore too immersed in their own groans and cries.

So it wasn't until Bill was standing right in front of them, that Tanya sensed his presence and she opened her eyes. Her big brown eyes filled with fear and shame.

The twenty year old cowboy had caught them in the act!

He was towering over her, in front of her, glaring down at her.

She couldn't even see his face, his clear blue eyes, under his Stetson, because the sun was glaring behind him. But she could sense his menacing presence.

"Uh!" she groaned as Jason continued to plug her from behind.

He was pretending she was Ramona and he still had his eyes closed. He didn't even know that Bill had come back into the scene.

There were questions in Tanya's eyes: will you tell? Will you get us into trouble? Will you fuck me? What will you do? But she couldn't speak.

And it only took a couple of seconds, though it seemed like an eternity.

Bill unzipped the fly of his pants and pulled out his big piece. It was thick and hard. He swung it in front of Tanya's face.

Her eyes grew even bigger as she looked at the menacing thing.

The question was in her eyes again. What do you want me to do?

Jason plugged her again. "Uhhh," she groaned.

"Open your mouth," Bill said in an undertone and he stepped forward.

She opened her mouth, knowing, and not knowing what was to follow.

He guided his hard penis into her mouth and she stared up at him. Silently he started swiveling his hips back and forth.

Now Tanya understood! She was to let him use her mouth as if it were her vagina!

Now she was trembling from head to toe. She was frightened. She tried to glance behind her but she couldn't. Because she had Bill's big piece in her mouth.

It was only now that Jason sensed that something had changed in the rhythm of Tanya's firm buttocks slapping backwards against his groin.

And then he saw the tall figure of the cowboy, outlined in the glaring sun.

He looked down at his sister, shocked. And then he saw that she had taken the cowboy's sex in her mouth and her eyes were closed and she was sucking it!

Jason put his hands down to his sister's ass to steady himself and he didn't dare stare into the cowboy's eyes. He just kept slowing pulling his tool in and out of his sister's hot nookie, watching the way her body moved to two rhythms as she took it from in front and from behind. Then he closed his eyes too.

Tanya was thinking about the horses. About how she was riding one big firm saddle and how she had another big firm piece in her mouth.

She was rocking between the one big piece of the cowboy in front and her brother's hard firm rod the way she swayed back and forth on her horse Betsy.

She spread her knees open much wider. She put her hands down to her open cunt to feel Jason's big bearded pole going in and out of her hole.

Her pussy squeezed and she creamed around it.

She was groaning now. Then she brought her hands up to her face and she felt the side of the big stick that the cowboy was pushing insistently farther and farther down her mouth. It was very scary, but still he kept it gentle.

Suddenly Jason was hot and he was ready to shoot. He couldn't hold off a second longer and he started to really bugger his little sister.

His hot throbbing rod sank in and she squeezed it and he shot off inside her. It was slow and gentle, and he shot off again. "Ohhhh," he groaned. He shot off again. The hot pussy squeezed him and he squirted.

"Ohhhhh," he fell out of her cunt and he rolled backwards on the blanket.

Now he was watching what the cowboy was doing to his little sister.

He had pulled her mouth up to fit to his groin better, now that her ass was not arching backwards to meet Jason's cock, and Bill was holding Tanya's chin.

"Uh! Uh!" Tanya squealed and squirmed, her panties down around her knees.

Bill was shoving his piece in way too far. She was gagging.

"Uhhhh! Errr!" she tried to break loose.

But the cowboy wouldn't let her. He stared down at her with a smile, silently watching her and knowing that he could do whatever he wanted. He had these two kids in his power, and they both knew it. He could get them in one hell of a lot of trouble.

After all, it would be Jason's sperm they found in Tanya's pussy, and not his, if he went back to the ranch and told them what had happened.
