Shawn ripped off her bikini halter, which had been still fastened around her abdomen like a belt. Shawn's roughness so excited her that pussycream and male cum oozed from her throbbing pussy and pooled between her legs on the stallion's back. Holding the reins in one hand, Shawn used his other hand to reach down and rub Cindy's crotch.
"Juicy!" he whispered, and he bit Cindy on the back of the neck.
She trembled with lust, her bones turning to rubber. If Shawn's strong arms hadn't been around her, she would have toppled off the horse. She rubbed her silky ass against Shawn's cock, cooing contentedly.
"Let's get back down so you can fuck me," she said.
"Get back down? Why the hell you think we got up here, anyway? Raise up, ya silly bitch. Sit on it!"
He wrapped his hands around her waist and jerked her upward, then planted her drooling crotch on the end of his rigid cock and let her go. She gasped as she was impaled to the hilt.
"Oh Shawn, my God!"
His cock was deeper inside her than any cock had ever been. He shook the reins, and as the stallion ambled away over the flat pasture, Cindy found herself bouncing up and down, her pussy sliding up and down his cock. She was in heaven.
She squirmed in her stepbrother's arms, gasping as his prick sliced into her womb again and again. His free hand was all over her – between her legs, massaging her clit, up and down her silky belly, all over her tits. When he pinched and rolled her nipples, she squealed with abandon.
"You got big nipples, bitch. I could bite 'em right off." Shawn leaned around to the front of her and licked her right nipple. Then he nuzzled under her right arm and sucked on her wet, shaved armpit.
"Mmm, I like the taste of a girl!"
Cindy let herself go. She was so weak and dizzy with lust that she felt like a rubber mannequin. The jouncing of the stallion made her tits flap and her head wobble. Her cunt gripped the boy's cock as it knifed inside her. The fuck juices flowed freely from her open crotch.
"Christ!" Shawn said. He lifted her off his cock with a powerful upward heave. "You almost brought me off, bitch. You got the suckingest cunt I ever plugged."
Cindy giggled deliriously, like a madwoman. "Put it back in, fucker. I wanna feel it."
Shawn humped his juice-drenched cock against her bare ass. "You are so fucking hot, Sis. I swear, the only bitch hot as you is your cocksucking mom."
"What!"
Shawn didn't bother to answer. He lifted her up, planted her ass on his cock, and jerked her back down. His rigid prick exploded up her asshole to the hilt. As a scream escaped her gaping mouth, she blacked out.
Shawn hugged his senseless stepsister in his arms, his completely ensheathed cock throbbing wildly in her asshole. It was a miracle he hadn't shot off on the way in. He'd never penetrated a tighter asshole. He feared he'd ripped the skin off his cock.
Cindy came to with a moan. For a few moments, she didn't know where she was. Then she felt the tremendous pressure in her bowels and started gibbering. It couldn't be! He couldn't have done that to her!
"My favorite hole," Shawn growled, nibbling at her neck. "My hog's in heaven. Get up, Sawgrass, ride us."
As the horse started to trot, Cindy writhed like a butterfly impaled on a stick pin. She bounced up and down, Shawn's armlike prick pounding in her asshole. She slid easily. His cock was well-greased.
"Mmn, feel this baby squirm!" Shawn said. "She's loving it. She's a real asshole bitch – my favorite kind."
Tears flooded Cindy's eyes and ran down her cheeks in rivers. Her entire body was beaded with sweat. Every cell of her felt as if it would explode. She honestly couldn't tell whether she felt pain or pleasure. The youth's red-hot fuckrod pulsed inside her, cauterizing her guts as it plunged.
Shawn lapped at her sweat-misted shoulders, at her upper back and neck. He rubbed against her, working his cock inside her as he rubbed her crotch, her stomach, her tits. His hands were rough, his fingers like sandpaper.
"Man, I ain't buggered an asshole this tight in months. Sis, you are one hot bugger-bitch!"
He pinched her clit so hard that she nearly blacked out again. As he released the pressure on her slick, bone-hard little pleasure-bud, as he rolled it gently between his fingers, massaging it, stretching it, such needles of fuck-itch saturated Cindy's loins that she nearly came. She arched her back, thrust her tits up high, and twisted her head from side to side as Shawn gnawed her neck.
"I want it!" she moaned. "Oh Shawn, I do want this! I love it!"
She wiggled her ass, grinding it around and around on the boy's rigid cock. Shawn spurred the stallion with his bare heels and it broke into a gallop. Cindy squealed, bouncing up and down on Shawn's cock. Her tits flapped like waterballoons on the verge of bursting. The fuck juices frothed from her contracting cunt, running down the stallion's black flanks.
"Oh man!" Shawn yelled. "Fucking wow!" His cock plunged like a battering ram up his stepsister's ultra-tight, wildly clutching asshole, and he felt the fuck-thrills to the tips of his grubby toes.
"Ohhhhh Shawn! Oh God, Shawn! Oh, I can't stand this!"
They exploded together, Shawn's cock spurting its first stream of jism up Cindy's asshole as her shitter made its first spastic contraction. The fuck-sensation surged like electricity through both their bodies, and both of them arched their backs as if they'd been shot. They shuddered and jerked, grunting like animals, grinding their bodies together as the pleasure surged through them again and again.
"Squirt it!" Cindy gibbered. "Squirt it in my guts!"
"Awww man!" Shawn moaned, crushing his stepsister in his arms as he rutted at her ass and filled her with his spunk.
As the horse galloped, the quivering ring of her asshole slipped up and down the veiny shaft of Shawn's flexing cock and milked it. Her asshole worked like a vacuum cleaner, sucking the molten jism from his nuts and through the itching core of his cock.
"Feels so good!" Shawn groaned. "So fucking good!"
"Yes!" Cindy panted. "Oh Shawn, God!"
Shawn brought the stallion to a trot, then to a walk. When the horse stopped, the woozy couple slid off.
They lay in the brown grass, their heads spinning, their chests heaving. They were panting as hard as the stallion even though he'd been the one to do all the running. The shiny cock of the stallion throbbed under his heaving black belly.
Cindy stared. The horse cock made Shawn's over-sized prick look more like a hotdog than a salami. It was as long as Shawn's arm, and just as big around. Its head was as big as Shawn's fist. Cindy was unable to take her eyes off the throbbing fuck-monster.
"Big, ain't it?" Shawn said. "Almost as big as mine."
"Don't you wish!" Cindy said.
Shawn smiled. "Almost as big, but just as horny."
CHAPTER SEVEN
It didn't take Shawn much prodding to get Cindy to crawl under the stallion and to take a feel of its cock. When she refused to touch anything so "filthy", Shawn simply pulled her up on her hands and started to lick her cunt and asshole. He loved licking out a girl's fuckholes, especially right after he'd fucked them. He jerked his hand up and down his hardening prick as he gave his bitch stepsister a thorough blowjob. When she was just about ready to come, he withdrew his tongue.
"Don't stop! Keep licking! It feels wonderful!"
"I'll keep licking just as soon as you crawl up under Sawgrass and get a better look at his cock." He gave her clit a flick of his tongue.
Fuck-itch shot through Cindy's cunt. She moaned, a bitch in heat. She couldn't believe she was still horny after all she'd been through, but she was not just still horny, she was hornier than ever now.
