Carson gulped. He told himself that their crotches must have become wet from the lathered pony's sweat. And yet it looked remarkably like cuntjuice that had seeped into the denim. Even as he stared at them, a frothy trickle of juice slid out from the cut off leg hole of Molly's shorts and ran down her slim thigh, leaving a glistening trail like the track of a snail. Despite himself, Carson could not help but stop and stare. He heard the girls giggle again. Embarrassed, the nervous man averted his gaze. But when he lowered his eyes, he was startled to notice an even more remarkable sight. The pony had a hard-on!
That huge erection was getting bigger and harder by the instant. The pony's balls were swollen, as big as melons under his haunches and its thick long stalk sprouted out so far that his cockhead almost jutted out between his front legs. That cockhead
was slick and black, the naked meat flaring out from the leathery sheath. A few drops of creamy spunk bubbled on the dark meat, oozing from the brute's open piss-hole and sliding down his prick-knob. Carson gasped in shock.
"What's wrong?" Wanda asked. Molly hooked one foot around and rubbed her ankle against the pony's prick experimentally.
"Oh, this damned pony has got another hard-on," she said.
"Yeah? He's a horny horse, ain't he? Hell, we just took care of him back at the stable before we came out for a ride- "
"Well, riding him bareback, with our cunts getting all hot and juicy, turns him on," Molly explained. Then she grinned. "Not that I mind it!"
"I guess we better empty his balls again, huh?" Wanda suggested. Carson stared in dumbfounded amazement. Were they serious? Were they just teasing him? They seemed to have forgotten his presence, for the moment. Molly drew her leg across and slid gracefully down to the ground. Wanda followed suit. As she raised her far leg, Carson saw a wisp of cunt-hair curling from the leg hole of her shorts and saw that her crotch was as swampy as her sister's. The two nubile twins, smiling and giggling, knelt down beside the pony, inspecting his hard-on. Carson was sure they must have forgotten he was there. But then Wanda turned and grinned at him.
"You can take pictures, if you want to," she said. Carson gulped. Well, they'd be wildlife pictures, of a sort, he thought, although they'd never be printed in "Field and Stream." The man was totally fascinated. He knew that he should hasten away from this bizarre depravity but he was rooted to the spot, his eyes glued on the naughty twins and their horny pony. His cock was so hard by this time that he thought it must be damned near as huge as the pony's prick, while his balls, which had not been emptied in two days now, were swollen so much that he was standing bowlegged around them. Molly reached out, palm upwards, and ran her hand along the length of the underside of the pony's stalk. "Ummm… nice and stiff," she whispered, tickling him under his swollen crown. Wanda cupped his massive scumbags in her hand, lifting and fondling the leathery cum skins and nodding, as if satisfied that they contained plenty of joyjuice. The pony snorted, pawing at the earth with one hind hoof and tossing his silky-maned head about. Sinew and muscle rippled in his powerful withers and haunches. He made a little humping movement, shoving his cock out over Molly's hand. It seemed obvious that the pony was well aware of what was going to happen to him and that it had certainly happened in the past. Carson felt that he should be disgusted by the scene but he was fascinated.
"We better get naked first, huh?" Wanda suggested.
"Yeah," Molly agreed. She turned to look at Carson. "You better take your clothes off, too, or else move farther away. This damned pony squirts cum all over the place and there ain't no sense in getting your clothes all slimy, right?"
The twins drew their tee shirts off then squirmed out of their shorts. Neither wore bra or panties. Their nubile bodies were as identical as their faces, thrusting tits capped by stiff pink tips and tawny triangles spreading on their flat bellies. They had slim, shapely legs and pert, teardrop-shaped asses. Ribbons of pussyjuice slid down the insides of their smooth thighs. Carson was amazed by their nonchalance. Naked before a total stranger and about to fondle a pony's prick, the naughty twins were perfectly at ease. Carson was anything but at ease. He was flushed, panting, lightheaded as his blood rushed into his prick and deprived his brain of oxygen. He was too embarrassed to strip naked, but his cock was hammering at his fly like a battering ram. He drew the zipper down and his hard-on burst out like a torpedo.
"Ooooh-nice cock!" Wanda exclaimed, gazing at Carson's rampaging, purple-crowned prick. Molly, too, looked at the man. She grinned wickedly. "Yeah, he's got a big one-for a man," she said. Then she turned back to the pony's gigantic cock. She stroked up the beast's thick prickrod and fingered his flaring cock-knob. The naked black cockmeat pulsed and more frothy dribbles oozed from his gaping cleft. Molly rubbed the slimy spunk into his prickmeat with both hands. As she fondled his cockhead, her twin sister played with his balls.
"We don't fuck him," Molly said, speaking to Carson over her shoulder. "We'd like to, but his cock's too big," she added.
"Yeah," Wanda sighed, wistfully. "It's so fucking big it don't even fit in our mouths.
We tried."
Carson staggered, lances of fiery lust transforming him, his mind spinning dizzily and his cock thundering. He envied the pony as he watched the girls caress that massive cock. How could a human prick compete?
"It's my turn in front," Molly said. Wanda nodded and Molly turned lithely onto her flank and slid under the stiff-legged pony. She sat on her ass, her slim back arched, head and shoulders thrown back. The pony's prick loomed out over her belly and tits, the black knob aimed right at her pretty face. She took his cockhead in both hands, holding the huge slab cupped between them. She began to frig up and down on the end of his cock, working her thumbs against the underside. The mighty black cockhead pumped and throbbed in her grip. Wanda gave the pony's scumbags another caress, then slid up and grasped his cockshaft in her hands. Holding his cock rod by the roots, she began to frig him up and down at the base of his cockstalk, while Molly pumped on his cockhead. They worked in opposite directions, with Wanda stroking up from the pony's balls as Molly pumped down from his cockhead. Their hands met halfway along his cockstalk. Then Wanda pulled back, skinning the brute's prick-knob as she dragged the leathery sheath away. The naked slab loomed out toward Molly's radiant face. The pony snorted, humping through their hands. His powerful haunches heaved as he slammed his cockmeat out, shoving his cock-head through Molly's hands and nudging his balls against Wanda's caressing grip. Those cum stuffed bags swung in and out and his cockshaft throbbed and vibrated. His prick-knob loomed out toward Molly's face, the tip flecked by slimy streaks of preliminary jism. She dragged his prick down, grasping the swollen crown so that when the beast humped again his cockhead skimmed up her belly from groin to tits. A milky seepage creamed in her tawny pubic triangle. Rivulets of cum streaked her slim belly and dribbled in between her tits. She moved his cockhead in her hands, touching the slippery tip against her stiff nipples. Cum oozed onto the rosy buds. She squirmed, pushing one taut titty tip right into the pony's open pisshole. The brute humped again and the black meat of his naked cock crown slid into the girl's cleavage. She wriggled against his cock, purring and panting. Arching deeply under him, she let his cockhead and half of his huge, thick cockshaft skim up her belly again. Wanda was pumping hard and fast on the root of the pony's prick as he fucked through her hands, driving up her sister's belly. Molly fell back and dosed her thighs around his prick-rod. His massive cockhead nudged into her crotch but, as she'd said, it was far too huge to slide into her waking, steaming cunthole. Her ass and hips tilted up as his cock-knob pushed against her pussyslot. Then the flaring prick slid out of her crotch and ran up her belly again. Now the dark meat of his cockhead was soaking with her cuntjuice, as well as his cum seepage. It lathered her belly and tits. Molly tilted her face down, gazing at that cream- slathered cockmeat. Her pink tongue slid across her parted lips and her jade-green eyes glowed. She glanced sideways, as if to make sure that Carson was paying attention, and then the naughty girl pushed her tongue out and lapped at the spunky tip of the pony's dripping cock-head. Cum and cuntjuice ran onto her tongue and the girl whimpered with delight. Carson watched her pink tongue lave all over the ebony meat of the animal's naked prick-knob, then push into his pisshole. Her lips parted and she kissed the slimy tip of his crown as she tongued up into his cleft. Jism ran down her chin. She gave a sigh and leaned back again as his prick slid down her titties and the knob came to rest on her curly cuntmound. Her mouth was open. Carson saw pony cum and cuntjuice glistening on her tongue and lips. Then he saw her swallow
