Pam's mouth dropped. "Oh, God!" she cried. It was more than she had bargained for. She bucked her hips, but Gypsy had other plans.
Gypsy plowed forward, driving the bloated head of his cock deeper. Half his throbbing shaft disappeared into Pam's twisting body. He rumbled deep in his throat. Her asshole was tight and clung to his shaft like gripping tentacles. His tail swished violently as the muscles in his rump twitched. He jabbed again.
"He's going deeper, Mommy!" Pam screeched. "Oooo, he's splitting me open!"
"Jesus," Gloria rasped. "He's fucking her ass!" She was wide-eyed and amazed. "How does it feel?"
Pam's face contorted in pain. "Owwww!" She gritted her teeth, her ass stretching wider as more thick cock meat filled her ass.
Gypsy was enraged. He jabbed forward, his prick now buried to his balls. He jerked back, pounding her again. His nuts swung like heavy weights, aching, bubbling with hot pony-cum.
"Relax," Marsha said, a note of concern in her voice. "Relax."
Pam was trying to, but it was hard. Gypsy was ripping her apart. Lights flashed behind her eyes and the pain made her dizzy.
"Mommy! Mommy!" she screamed.
Her clit was being mangled with each jab. The pain and the pleasure blended erotically. She jerked her hips. Breathing deep with each powerful thrust, she began to relax.
Gypsy jerked back, slammed forward, his cock skewering her tight asshole. He snorted, drool dribbling from his mouth. The tightness of Pam's asshole had him crazy. He stabbed her again, his rump quivering. His neck muscles strained as he whinnied shrilly.
"Mommy! He's in all the way!" Pam's head was reeling. The pain was fantastic, just the way she had wanted it. And the pleasure was even better.
"I can see, baby," Marsha said. Her throat was dry and her eyes were fixed on Gypsy's plowing prick.
Pam squiggled back, taking each jab greedily, accepting the punishment and loving it. "Oooo, he's reaming my shitter!"
Gypsy's cock pierced her young body again. He shoved, moving the bench a few inches as he drove deeper inside her asshole. One hard plunge buried him to the balls again and he snorted in triumph.
"Oh, Mommy! It's great!" She leered at her sister, then deliberately slammed her ass back at Gypsy's plowing prick, skewering her own asshole.
Gypsy jerked wildly, pounding Pam, mashing her clit into the edge of the bench. He repeated his powerful thrusts, his speed quickening, his prick swelling larger inside her tight asshole.
Dazed and shuddering in spastic bliss, Pam quickened her own jerky movements. "Harder, Gypsy! Harder!" She wanted it all.
Gloria licked her lips jealousy. Her kid sister was getting her asshole stuffed with Gypsy cock. She wanted it now. "Fuck her, Gypsy!" she screeched. "Rip her open!"
The screaming teenager quaked under the brutal assault of the horny pony. She swiveled her hips, her ass going around and around. The action rubbed her clit into the wood and she howled.
Panting, hunger blazing in her eyes, Pam clawed the bench. She felt each stab, each throb of his prick as he drove it in and out of her ass. Her narrow asshole was almost as sensitive as her hot bubbling pussy. She wanted more, craved it like a drug.
Gypsy pounded. He shifted on his hind legs, his rump slamming his cock in and out of the squealing teenager. His balls rumbled to unload. A shrill neigh came from his rubbery wet lips.
Gloria was hot as a firecracker. She wanted what Pam was getting. "Fuck her, Gypsy. Then fuck me!"
"Yeah," Pam wailed deliriously. "He's going… so… fast!"
Drool slobbered from her mouth. Her eyes were glazed with desire. Her young slender body took the full brunt of Gypsy's fierce stabbing. Her knees scratched in the dirt. Her clit was raw, throbbing, swollen with blood.
Pam slammed back with equal force. Her ass cheeks jiggled as their bodies met. "Oooo, it's heaven! I love it! Gimme more, Gypsy!"
Pam shuddered, anticipating the hot thick cum that would soon fill her asshole. "He's gonna cream! I think he's ready!" She lunged back, getting all of Gypsy's thick cock. "Fuck my ass!"
The pony's hard frantic pounding bombarded the writhing child. Her ass worked in tight jerky circles. Her clit was swelling, her own climax rapidly approaching.
"Cum, Gypsy. Cream her!" Gloria yelled.
"Fuck him back," Marsha growled. "Make him cum!"
Pam gurgled in her throat. Her face was flush to the bench. Her arms were stretched forward, her fingers curled tightly around the wood. "I'm gonna… cum! I feel it! I'm on fire!"
Gypsy's nuts were also on fire. They whacked against her each time he jabbed forward. His prick grew thicker, longer. He was ready to blast.
Ramming back, Pam made one hard lunge. She was shoved back into the wood. Cunt juice gushed from her empty pussy and her clit hit the wood again and again.
"I'm creaming! Aghhhh!"
Pam's forehead beaded with sweat. Racking spasms attacked her body one by one. The faster Gypsy pounded, the more she creamed. Sudsy pussy-cum flooded her pussy and spilled out over the pink swollen folds. It oozed down her quivering thighs.
Gypsy's coat glistened with sweat. He fucked away at her ass. His balls erupted and he whinnied. Hot stringy wads of cum splattered deep in Pam's tight asshole. Jerking, his head swaying, he spewed more thick cum into the child's writhing body.
"He's cuming! He's cuming!"
Pam went insane. The hot cum gushing into her ass triggered more climaxes. Her tits, crushed into the wood, were scraped raw. Her clit, mashed into the edge of the bench, throbbed as more explosions erupted deep in her twat.
Gypsy plowed forward, driving Pam and the bench across the ground. Thick globs of cum blasted from his pisser, greasing a lightning fast path for his oversized cock. He lunged with more force, whacking deeper into her asshole.
Pam cried out. The powerful thrusts were turning her mind to mush, knocking the wind out of her. She felt the deep squirts and swooned.
White gobs of Gypsy's cum poured from her ass as he pounded her. She humped up her ass, only to be driven back against the bench when Gypsy slammed forward.
A continuous jet stream of cum flooded Pam's asshole. His cock head split her wide open, going deep, his own cum greasing his shaft. He lunged, neighed, tossed his head high in the air. Another lunge dragged Pam and the bench across the barn.
Pam screamed, her orgasm and Gypsy's violent thrusts sending her into a faint. She fell limp, panting as her eyes rolled into her head.
Gypsy jerked back, his spent cock popping from her asshole. It was covered with cum. He snorted and pawed the earth, his eyes still blazing.
Pam moaned, rolled off the bench and sprawled out on her back. She stared up at her mother. "God, it was fabulous." She fainted.
Gloria steadied Gypsy, leading him quietly back to his stall. "Is Pam all right?"
"She's fine," Marsha said, helping her young daughter to her feet.
Pam moaned. A dreamy smile graced her face. "I ache all over."
Without bothering to dress, Pam, with her mother and sister, left the barn.
"Tonight, we celebrate," Marsha said.
"I think I already have," Pam laughed as they all ran naked into the house.
