It was a normal day in sodor. The trains were gliding along the tracks, get passengers to and back.
Thomas however, had a "break" today.
Y/n came to do his weekly inspection on the trains. But little did y/n know that Thomas had wanted to rail him since day one.
At night, he would have dreams of y/n laying on the track, thomas speeding toward his tight pink hole, stretching him out beyond he could imagine.
When y/n came towards him thomas immediately switched to his human form. He couldn't bare to see y/n in his train from without rushing towards him, his long rod impaling his ass.
You've been acting strange since I've got here."
"Y/n I just... I..-"
Y/n looked deep into Thomas's eyes. Softly holding his hand to his cheek softly.
"What is it thomas? Talk to me-"
Thomas leaned into y/n slowly and softly kissed y/n's lips slowly deepening the kiss. When the pulled a part- thomas face now flushed.
"Is this what you wanted? Or is there more?" Y/n slowly started kissing around Thomas's face. "I-I want more, I always thought about.." thomas trailed off feeling embarrassed.
"Tell me Thomas, you can do anything you want. "
"Anything? Really?"
"Of course, you haven't been doing good around town, and the others are worried about you, especially percy.. It's my job to fix that."
Thomas blushed. He knew how his best friend could always tell when something was wrong, but now he was wonder what exactly percy knew, and told y/n.
"Did he tell you anything?"
"Maybe, but let me do a run down first-"
Y/n leaned Thomas down on his bed and straddled him. Both making eye contact with lust in their eyes.
"First, let's see what's under here" y/n lifted thomas shirt up and fully took it off. Y/n played with his nipples, licking, kissing, and pulling them.
Thomas moaned at the treatment. Y/n smiled. "That's working fine" he thought to himself. He kissed down his stomach reach toward Thomas's pants, slowly removing them.
"W-wait- I-..want to take charge.."
Y/n gave an amused smile towards Thomas and laid down on the bed looking lustfully at him. "Go ahead Thomas"
"Call me conductor." Thomas said lowly.
"Yes, c-conductor"
Thomas then stood up and pointed to the tracks. "Lay on them, now" y/n crawled over to the tracks laying on the cold metal. Thomas undressed y/n and got harder and harder looking at his naked body, his long skinny peeny.
Thomas, taking off his own clothes he got on top of y/n. "Rail me conductor" y/n said breathlessly.
Then, Thomas took his big fat cock and slammed into y/n hole. Y/n moaned loudly, never feeling soemthing so big and warm.
"Y-yes!! YES!"
Thomas moaned.
"Choo! choo! Choo!choo!~~~" Thomas moaned.
Suddenly, unintentionally, thomas felt himself slowly transform into train form.
His funnel forming, hot steam coming out of it.
Then, Thomas transformed into his train form as he came black soupy liquid came out. Filling up y/n's hole.
When y/n opened his eyes he saw thomas. Full train, panting,sweating.
His cock that grew 3x bigger, left a bump in his stomach.
Thomas and y/n panted until they heard a train pulling in.
Percy's voice tricked through the tunnel. "Thomas are you there? I didn't see you at all today-"
Thomas and y/n perk up at his voice. Thomas go backwards out of his shed.
"P-percy! Hi- how was deClivering the mail?
"It was.. alright I sent y/n to check up on you- is he here? He didn't come back to the station."
"He decided to uhh- go and talk with the other conductors- yeah"
Percy eyed Thomas suspiciously looking behind him and looking at Thomas.
"Well, if you're feeling better, I'll just go and finish my tasks around sodor."
Percy begins to take off, but not before saying:
"I hope I prepped y/n enough for you"
