Billy had seen enough, had seen more than enough, had seen more than any boy could stand without losing his mind totally. He felt the same red heat he'd felt the other night in that tent in Tijuana. Every cell of his body tingled as if he'd become one big hard cock. He didn't care anymore what happened or what anybody thought. Maybe nothing would happen. His mom hadn't said a word about that embarrassing thing he'd done in the tent in Tijuana – maybe she wouldn't say a word about what he was going to do now. Not that it mattered. He couldn't help himself.
He stumbled out of the empty stall, leaving his hiding place and peephole. His athletic trunks tore as he forced them off, but he didn't give a damn. All that mattered was his mom's beautiful naked ass, which stared him in the face as he staggered toward it, half tripping as he stepped out of his trunks. He didn't have time to get off his jockstrap, not that it mattered. His cock and balls were out one side of the elastic pouch, naked and ready for action.
He glimpsed his mother's face as she turned it away from between Sally's legs, saw the horse-cum dripping from her lips, saw the look on her face as if she'd seen a ghost. He couldn't let that expression bother him, though. Focusing all his attention on her sexy ass, he dropped down behind her and rammed his cock between her legs. He couldn't believe how wet she was. He couldn't believe he was doing this. He found her cunt and rammed his cock up it to the hilt, grinding his belly against her full round ass. Her ass-skin felt like hot silk. Her cunt felt indescribable around his rigid cock! He'd never felt so good in his life and he started to fuck.
Connie was sure now that this was all a dream. This couldn't be happening! That huge stiff cock plunging in her cunt couldn't be that of her own son.
Billy moaned. His arms hugged her around the belly. His hard abdomen smacked her ass again and again. His cock pistoned inside her like an oiled cylinder. The feeling was incredible. How could any dream feel this real, this good! How could any phantom cock be that hard, that hot?
"Lick my pussy," Sally hissed. "Hi, Billy, you're being naughty."
"Shut up!" Billy said, his breath hot on Connie's naked shoulder.
"Mother-fucker!" Sally taunted.
"I said, shut up!" Billy growled. Connie knew now she wasn't imagining anything. The sound of her son's voice was too real. The smell of his breath was real. Pleasure saturated her loins and she wiggled her ass excitedly, fucking her son's cock.
Sally shoved her naked toes in Billy's face. "Lick my toes, Billy."
"Shut up!" the boy said as Sally rubbed his cheeks with her fool and tried to wiggle her toes into his mouth.
"Suck 'em," Sally said. "They're hot."
To Connie's surprise, the boy opened his mouth, letting the girl feed him her toes. He munched, sucking, licking.
"Oooh, that feels sexy!" Sally cooed. She reached between her legs, opening up her pussy wide. "Come on, Connie, lick."
The aroma of teenaged cunt and horse-cum poured from the girl's open cunt like hot steam, and Connie felt drugged. She started to lick again, sucking out the strong-flavored horse-cum, chewing on the young girl's puffed-up pussy-slabs.
"Oh Mom, you're so sexy!" Billy mumbled. "Oh wow!"
He bucked against her ass, riding her wildly, pistoning his cock inside her. His tight belly clapped against her ass and his cock squished rhythmically in her clutching pussy.
"Oh, Billy!" Connie moaned, her mouth full of hot pussymeat. "Oh Billy, fuck me!"
She sucked hard on Sally's insatiable young cunt, swallowing horse-cum and girlish fuck juices. Her sucking caused her own cunt to tighten and contract just as it was causing Sally's to. As her pussy clutched rhythmically at her son's sliding cock, she heard him moan and she moaned with him.
"Eat my toes!" Sally hissed. "Suck my pussy! It feels so good!"
Billy munched on the young girl's toes, humping faster against his mother's hot ass. Connie plunged her tongue up Sally's cunt, twisting it in circles, trying to hit all the sensitive crevices of the girl's quivering cuntal walls.
"Eeeeeeeh!" Sally squealed. "I'm coming!"
And she arched up, grinding her cunt in Connie's mouth, ejecting horse-cum and pussycream from her spasm-wracked pussy-hole.
The girl's orgasm seemed to pass into Connie's mouth, thrilling Connie's lips and tongue. As Sally's spasming cunt sucked Connie's nipples quivered, tingly and tight and hard. Connie churned her ass, grinding her cunt around and around on Billy's cock. She felt spasms beginning in her loins.
"Ohhhhh Mommmmmm!" Billy's cock flexed powerfully and he exploded his cum deep into her womb.
"Billy!" she gasped, and, she exploded with him.
"Ohhhhhh!" they moaned in unison, the pleasure whirling through their coupled fuck meat, Billy's sizzling cum spurting repeatedly into Connie's contracting cunt.
The boy had a powerful squirt that thrilled Connie. She loved the feeling of his cock flexing inside her, swelling and contracting and filling her full of hot cum.
"Nice show," said a voice that startled them all.
Connie swung around to see Matt. He had a funny grin on his face – that crazed look again, and the look he got when he was sexually excited. In his right hand he held his erect cock which he was slowly massaging. His other hand gripped the halter of a chestnut stallion, which was sniffing the air, its long red cock hanging out of its sheath and throbbing.
Matt shook his head. "Imagine you, Connie, fucking your own son! What's this world coming to?"
"I fucked her," Billy said proudly.
"I'm sure you did," said Matt. "But it takes two to fuck, doesn't it?" His eyes never left Connie's face, and his wicked grin never left his own face.
He led the stallion farther into the triple-sized stall. Connie could see that it was wearing the same halter that had been on Midnight, its buckles and loops ready to be attached to the straps and ropes dangling from the overhead beams.
"Get out of the way, you little whore!" Matt grabbed Sally's foot and nearly yanked her off the platform. "All right, Samson, up you go."
He lifted slightly on the halter, and the stallion reared up gracefully, planting its front hooves on the platform. The stallion's cock flexed up, knocking against the edge of the platform and Matt told Sally to adjust it. The young girl lifted the big cock, bending it sideways to clear the edge of the platform, then laid it in the straw on the floor of the wooden structure.
Matt guided the horse closer, until the hanging straps and rope lined up with their points of attachment on the halter. Sally helped him secure the fastenings, then started to climb up onto the platform.
"And what do you think you're doing, young lady?" Matt said as he grabbed Sally by her hips, rubbing his hard cock against her wiggling young ass.
"I wanna fuck Samson," the girl said.
"You might want to, but you're not going to," said Matt, glancing sideways at Connie. "I think a woman who fucks her own son oughta know what it's like to fuck a prize stallion."
Connie's first impulse was to turn and run. But she just stood there shaking, her eyes on the magnificent throbbing cock of the restless stallion. Billy's warm cum oozed from her cunt and dribbled down her legs.
Matt glanced down as Connie squeezed her thighs together. "Come on, baby, you're dying for it, and you're all greased up already. Now's the time, bitch. You'll never be readier."
