It was just after 7:00 when the heat from the early morning August sun made the trailer too hot to sleep. Maggie and Molly slowly rolled out of bed. They essentially had the day off and got to sleep in. Their parents, Emmitt and Betty, had gone to town for the day; Mom to work and dad to medical appointments. Dressed in their baggy t-shirts, with nothing underneath, they went to the small bathroom in the trailer to pee. They finish, then shuffle down the hall to the kitchen to eat. Their little brother Earl is sound asleep on his bed; the living room sofa. Their small trailer in a holler outside of Hazard, KY only had two small bedrooms; one for mom and dad, and the girls shared the other. Earl was relegated to sleeping on the sofa.

Earl got his sister’s attention when he rolled over on the sofa, kicking the covers off, and moaning in his dream world.

“You better wake up Earl” Maggie said to Molly.

Grinning, Molly nodded in Earl’s direction in response to Maggie. Looking over, Earl had kicked back the sheet and was laying on his back. His t-shirt was pulled up to his waist, and with no underwear to hide his privates, his morning wood was standing at attention.

——-

In Earl’s dream, he is sitting at his desk in Algebra class. Ms. Davis, the cute young dark-haired, tanned teacher, is sitting at her desk, legs spread wide, exposing her hairy bush to him. His erection is bending to spring from his jeans. He moves trying to straighten his bent, cramped hard-on.

“Earl, can you come to the board and show the class how to solve this problem?” Ms. Davis asks.

Earl nervously stands, his erection forcing his jeans out. Embarrassed, he walks to the board. He stares at some mysterious equation on the chalkboard, when suddenly he feels a hand on the small of his back. Turning, Ms. Davis is squatting down, skirt up to her waist, her tanned, dark nippled tits hanging out of her blouse and she’s unzipping his jeans. He watches as she wraps her lips around his cock and begins to suck. He closes his eyes and leans back against the chalkboard as Ms. Davis swallows his cock. He’d never felt such pleasure in his young life.

——-

Maggie turned in her chair and dropped to her knees beside the sofa. Leaning over, she gently took Earl’s erection in her hand, and slowly lowered her lips over the head. She was careful to go slowly, not to wake her dreaming brother. His young cock, although only five inches long, tasted so good. She slurped away, sucking harder and faster. Maggie suddenly felt a hand on her naked ass. Molly had slipped down beside her to watch the action and slowly began fingering her sister’s wet, hairy cunt. The more Maggie sucked, the more Molly fingered her hard. Leaning over, she ran her tongue up the crack of her ass, slipping it into her tight ass. Maggie moaned and squirmed, sucking harder.

——

Earl was leaned back against the chalkboard in his classroom dream. All the students had somehow disappeared and his hot young tanned teacher was sucking hard on his cock. He could take no more. He was going to ace this class and start by dumping his whole load, deep down Ms. Davis’s throat. Thrusting his hips forward, he exploded in her mouth, shooting cum deep into her throat. His balls pumped hard, draining them of his virgin seed. This had been his first time and he was spent. Shocked from his dream, he felt a hand on his stomach. He tried to sit up on the sofa, but looking down, there was his oldest sister, Maggie, sucking hard on his cock, draining the last few drops of cum from his young balls.

——

Earl was speechless as he watched Maggie sucking on his cock. Looking over he could see his sister Molly with her face buried in Maggie’s ass. Maggie moaned loudly then suddenly popped her head up from his sill throbbing cock and screamed out as she was overcome by orgasm. Earl was now up on his elbows. He was shocked by what was happening. Maggie’s trembling orgasm finally ceased and she looked up at her little brother, his cum dribbling from the corner of her mouth. Licking it away with her tongue, she smiled, “Time to get up Earl, we got work to do. Sorry to wake you this way but it looked like you needed some help with your dream.”

Embarrassed, Earl grabbed at the sheets to cover himself. “Um, sorry sis, I um, I um….”

“It’s ok Earl, this will be our little secret” whispered Maggie. Looking on, Molly smiled in agreement.

The girls got up and returned to their breakfast, as Earl jumped up from the sofa and trotted down the hallway to the bathroom. He joined them shortly but was still too embarrassed to make eye contact until Maggie said, “Daddy wants you to mow the yard and clean out the chicken house when you finish breakfast.”

“Well, what are y’all gonna do?” he inquired.

“We’ve got to work in the garden then chores to do in the barn. We’ll be back when we finish. You stay down here,” Maggie stated.

With that, both girls got up and headed to their bedroom to put on their “work clothes”. Emmitt was strict that the girls wore only their “work clothes” when doing chores, partly to avoid getting dirty what decent school clothes they had, and second because he enjoyed the view of their baggy cutoff jean shorts, and ratty, almost sheer, wife-beater tanktops. Even in her young age, Maggie had already developed a nice firm set of tits, and a beautiful light brown bush to make any woman proud. Emmitt would know, both his tongue and cock had been in it several times.

Three minutes later the girls bounced down the steps and headed to the garden. Earl sat at the kitchen table thinking back on his morning experience. Just the thought of his sister giving him his first orgasm, other than the occasional wet dream which didn’t really count, made his cock stiffen again. He wanted more.

“Let’s get this work done in the garden so we can go play in the barn” Maggie chuckled. Molly knew exactly what Maggie was thinking. They’d discussed their fantasy late last night, in bed. They spent the next hour picking beans and corn, before dropping their harvest in the shade at the side of the barn. Relaxing in the shade of the barn, Molly whistled for Thunder, their little pinto pony stallion. A few more loud whistles and Thunder came running into the pen behind the barn. The girls put some grain in a bucket, a lead on Thunder and led him back into the last stall in the barn.

“Thunder, I’m so horny after sucking off Earl this morning, that I think today is your big day,” grinned Maggie. “Mom and daddy won’t be home for hours, Earl is busy, so let’s try it” she said looking at Molly.

“Like we talked about last night?”

“Yep, go grab a bale of hay and that blanket. I’ll get more grain.”

Molly returned and dropped the bale in the stall. Rubbing Thunder on the side to keep him calm, she slid the blanket-covered haybale under Thunder’s belly. Maggie dumped the rest of the grain in his bucket then turned, untying her baler twine belt and her baggy cutoffs dropped to the floor of the stall. Tossing her tank-top aside, she rubbed her light brown bush and felt at her stiff nipples and already wet cunt. Being naked felt so good.

Squatting down she began to rub his cock. It didn’t take much for him to release his cock from its’ sheath and she stroked in slowly. With each stroke, it stiffened more, growing in her hands until the head mushroomed out. Thunder stomped his foot and whinnied as she stroked his brown, white and pink 16” cock. His 2 ½” thick, monster cock, with its’ big 3” head throbbed against his belly.

“Ok Molly, rub him and keep him calm while I crawl under.” Maggie slid under Thunder’s belly, laying on the haybale. She swung her right leg under until she was positioned directly under his belly. Feeling for his cock she slid closer until she could place his head at her opening. The feel of her hard nipples rubbing against the coarse hair of his belly made her even wetter. Lying on her back, she could feel her juices run down the crack of her ass. She was ready.

Grabbing his cock, Molly whispered instructions to Maggie, “slide closer, bend your knees way up, spread your legs wider.” Molly rubbed his 3 inch wide cockhead up and down against the opening to Molly’s wet cunt, spreading her lips wider with each stroke, until they finally parted, allowing her to force his splayed head into her cunt. Maggie continued to slide back tighter against Thunder’s cock until Molly finally got the head inside. Thunder reacted to the hot wetness of her cunt and thrust forward. Maggie yelped as his fat cock head and first six inches pushed inside. Another thrust and she gasped in pain and his cock pushed even deeper. On the next thrust his cock slammed against her cervix and she moaned, both in pain and pleasure. It had been a while since Thunder had bred a mare but he knew exactly what to do. He humped harder and harder, sliding Maggie back and forth on the haybale with each stroke, impaling her with his cock. His big mushroom head gripped the walls of her cunt and pulled her back, before slamming her forward again.

Molly had dropped to her knees to watch, while sliding her hand into her shorts to rub her cunt. With Maggie holding her knees bent back and her ass spread wide for Thunder’s massive cock, she watched as he pounded away at her sister. In no time, Maggie screamed out, reaching her first orgasm. With each stroke, Molly could see Maggie’s cum being forced out by his fat cockhead. Gasping for air, her moans grew louder as he buried his cock deeper and deeper with each thrust. Her ass jerked on the haybale with each stroke. There was still four inches of pony cock he was trying unsuccessfully to push inside her. Her young cunt was simply not deep enough to hold all of his cock and each thrust lifted her ass completely off the haybale.

Unbeknownst to either girl, Earl hid in the hayloft peering down at the beastiality spectacle below. He jackhammered away at his hard young cock, watching his sister in this wild, raw act getting fucked by Thunder. Never had he seen anything like this, or experienced a day like today. First, shooting his first load of cum deep into his oldest sister’s throat and now watching her get fucked by the family pony.

Maggie was out of control. Her body shook uncontrollably as Thunder pounded away, his cock dragging her back and forth on the haybale. Her second orgasm was rapidly approaching and she could feel Thunder picking up his pace. She knew he was ready to empty his cum filled balls and just that thought sent her over the edge. Her whole body erupted in orgasmic ecstasy. On the next thrust forward, Thunder held the position and his first load of pony cum sprayed hard against her cervis, filling her cunt with so much cum she thought she would explode. He jerked back then slammed forward again to dump another load. Cum sprayed out around his cock and ran down her ass, covering the blanket. Her cum filled cunt squeezed hard on his fat cock, draining more cum from his balls. One last thrust and he dumped his final load. His whole body quivering, Thunder stepped back, slowly pulling his cock from his new human mare. With an audible plop, his three inch wide head popped out of her cunt. The sudden emptiness made Maggie gasp and rivers of cum ran down the crack of her ass.

Maggie turned to look at her sister squatting beside her and suddenly spotted Earl, in the loft, looking down, over Molly’s left shoulder. She scurried to get out from beneath her pony lover, embarrassed at being caught by her younger brother.

“What are you doing up there? I told you to stay at the trailer. Get outta here” screamed Maggie.

Earl was speechless. What could he say? He’d just witnessed his sister getting fucked by a pony and he had just shot his second load of the day onto the hay of the loft. He turned and crawled down the back ladder to the loft, and ran to the trailer.

“Oh my god, I’ve never seen anything like that” exclaimed Molly.

“Trust me sis, I’d never felt anything like that!” Maggie replied.

Turning to walk to her shorts on the floor of the stall, Maggie’s legs felt like butter as gobs of cum ran down her legs. Her cunt was so sore, both from pain and pleasure, she could barely walk. She walked to front door of the barn, turned on the hose, and sprayed the cum off her legs and crotch as best she could. She gingerly stepped into her cutoffs, pulled them up over her sore, naked ass, tied her baler-twine belt, and headed to the trailer. She had to convince Earl to keep his mouth shut or Emmitt would make her pay.

Running to catch up to her, Molly whispered, “so, how was it?”

“You’ll find out. It’s your turn next!”
