One day, Thomas felt like being naughty. Everyone told him that taking a left at the fork on Magic Mountain would always lead to trouble, but he wanted an adventure. He then started on his merry way towards the mountain. Upon getting to the fork in the road, he asked himself, “Do I really want to do this?” He thought and thought. “Sure I do! I'm sure nothing bad will happen.” He then turned left and trucked his way up the mountain. Suddenly, he found himself entering a dark cave. “Uh-oh! I'm scared of the dark!” he said, squeezing his eyes shut. Suddenly, through the back of his eyelids, he could see a bright light. He opened his eyes wide as he gazed upon an entirely new world with all kinds of colors, shapes and sexy pony backsides. “Oh, boy! I'm gonna have so much fun here!” he said as he looked upon a white unicorn. His pipes grew larger.
"Why, hello there," the unicorn said. "I didn't know trains could have faces on them."
"Shut up and bend over, slut."
"What...?"
"I said BEND OVER!" Thomas then drove off the tracks, smashed Rarity to the ground and shoved his giant pipe cock up Rarity's cooch. Rarity screamed in agony, making Thomas's member grow larger. He loved it. He pushed her down further and licked up her tears before ejaculating oil into her marehood, rupturing her ovaries at the powerful climax. Rarity didn't move, other than the heavy tears that were streaming down her sexy, dirty face.
Nobody seemed to notice. None of them really cared about Rarity much, and most of them were expecting something like that to happen eventually anyway. Then, Thomas saw her. She was pink, small, and had a diamond crown laying on top of her head.
Then Thomas drove himself over to the pink filly and gave her a genuine grin. She seemed rather timid about a train looking her in the face. Thomas thought that this would be a wonderful opportunity to teach her how to get over being shy.
"Hello, little girl," Thomas said with a grin.
"Please don't hurt me," the filly responded. Thomas was puzzled. He hadn't even told her about his tingling private parts. How did she know he wanted her to solve it?
"Don't worry," Thomas said with a smile. "It'll only hurt at first."
Then Thomas grabbed her by the mane and put her mouth on his train cock. Diamond Tiara struggled, fighting for dear life. She tried screaming, but that just made the most wonderful vibrating feeling on Thomas's dick.
Then, Thomas started feeling curious again. "I wonder what would happen if I tried that hole?" he asked himself.
"NO! Please don't! I'll do anything!"
Thomas then rammed his pipe penis into the filly's anal cavity, splitting it in half. It was so tight against him that he was already starting to feel a pulsing sensation. With a deep breath, he shot oil into the filly's orifice. It pulsed like a fire hose, going so far deep that it came out of the filly's eye sockets, killing her instantly. Thomas was having so much fun on his adventure.
Thomas felt very proud of himself. He knew how much everybody loved sex, and he probably just made two ponies' days so much brighter.
"HEY!" a rainbow-maned pony shouted as she flew down in front of Thomas. "What's the big idea? You wanna go? Put 'em up! I can take you!"
"Oh, boy!" Thomas thought. "I hope she knows what she's getting into, or should I say, what's getting into her."
Thomas wrapped his wheels around the pony and threw her to the ground. "OW! My wings! I think they're broken! I can't feel my wings!"
Thomas smiled at how easy he knew this was going to be. "Spread em." The rainbow-maned pony started to cry. "I said spread em!"
"I'm trying, but I can't move my legs either."
Thomas was always taught to help others. In this case, he grabbed Rainbow Dash's two hind legs and ripped them backwards. The pony looked so sexy while she was on her back that Thomas just wanted to take a moment to enjoy her in this position. He ran his wheels up his pipe penis, moaning loudly in the form of his whistle blowing. "Show me how much you want it!"
Rainbow Dash, scared for her life, tried moving her mouth up to suck his cock for him, but Thomas smacked it across her face, snapping her neck. Suddenly, she looked that much hotter. "HERE IT COMES!" Thomas shouted as he launched his greasy seed into the air. Oil rained all over. Ponies ran for their lives, but in seconds, the town was flooded in Thomas's train sperm.
Thomas was suddenly feeling tired after all his exercising. "I should probably take a nap," he said. "Naps are a great way of replenishing energy."
And after a nice, peaceful nap, it was already dusk. "Night time already?" he asked himself. "I guess I'll only have time for one more adventure before I need to be back home." So he went looking and looking for whatever he could find. That's when he saw colorful lights flashing to fast musical beats. "That sounds like a birthday party! I love birthday parties!"
He trucked his way toward the lights as fast as he could go, arriving at a rave with lots of colorful ponies dancing happily to the music. "I love dancing," Thomas said to himself, but something caught his eye before he joined in. He saw another white unicorn. This one had a blue mane and a very unique pair of sunglasses. Thomas's privates started tingling again, and suddenly he wanted to make another friend.
He rolled over to the unicorn, who waved at him happily. "Spread your legs, you sexy used up tramp."
"What?" the unicorn asked with a puzzled look.
"I said get your good for nothing flank down here now!" Without saying another word, the unicorn complied. Thomas spread her legs and jammed his monster cock up Vinyl's orifice.
"OH YES!" Vinyl screamed. "Train cocks are my fetish!" Thomas began humping her as hard as he could, forcing all 16 tons of weight onto Vinyl's spine. "SO GOOD! OH BABY!" Thomas was getting tired of Vinyl enjoying it so much. He then shoved all 12 feet of his cock up Vinyl's butthole. "OH YES! I'm gonna... I'm gonna...!" Suddenly, Vinyl was excreting all over Thomas's penis. "YEEEAAAAAHHHHH!!!" She rubbed the feces all over Thomas's cock and licked up and down the shaft.
Suddenly, Thomas knew why he wasn't supposed to go to Magic Mountain.
"I'm sorry, but I have to get going back home. I--" Without notice, Thomas's penis shot gallons of oil into Vinyl's mouth. The unicorn fell backwards motionless. Hopefully none of the ponies saw, so he just made his way back down the tracks.
When he returned to his home, his friend Toby asked, "Thomas, where have you been?"
Thomas smiled sweetly and replied, "I went exploring, of course."
