I wake up from my sleep and I look at the clock near my bed. A few hours have passed after my exercise with Rainbow Dash. I proceed to go look at myself in the mirror, and I notice that I look like a mess. If I had any plans for the next hour, I forgot all about them as I took a shower, combed my hair, and picked my new outfit for the day.

I decide to wear the overalls Applejack gave me and a simple white t-shirt underneath. The overalls felt tight like before, but I didn't care about it. I looked at my phone to see if so have anything planned, and as I put my phone away, I hear the doorbell ring. I go to open the door, and as I do, a familiar voice rings in my ear.

"Hey there Sunset!" I recognized the high energy voice right away, belonging to Pinkie Pie. I remembered that she was coming over today, since it was her day off. She had on a tank top and a puffy miniskirt, while it was standard for Pinkie, I don't think she knows how scandalous her outfit can be. I welcome her inside and she proceeds to place her backpack on the table.

"So, anything you want to do, Pinkie", I ask her?

"Oh, that's a good question", Pinkie replied. "You see, I never think about what to do when I get to someone's house, I just think about seeing my friend and that's what makes me excited to go see them in the first place." Pinkie then proceeds to ramble on, but at the very end of the rambling, she says, "By the way, I love your overalls, Sunset."

"Thanks", I reply. I adjust one of the straps, and that catches Pinkie's attention. She was looking at my overalls with her attention placed nowhere else, and it got me turned on. I usually find it fine to be aroused around Pinkie, since she usually never cared if you have a bulge in your pants. It could be because she missed sexual education during biology or she forgot about it the next day, but sex was never something on her mind.

"Ooh, that reminds me. I brought some things with me today," Pinkie said almost out of the blue. "I'll be right back." Pinkie gets her backpack and dashes to my bathroom, almost in record time. I decide to sit on the couch and wait for Pinkie to come back down. I adjust the straps of my overalls again and my body gets aroused some more. Since Pinkie is away, I decide to gently rub my crotch against the denim overalls, causing my penis to get erect and my nipples to get hard. The thought of jerking off is in my mind, but since I do have a friend over, I have to restrain myself. As soon as my body calms down from the rubbing, the bathroom door opens and out comes Pinkie Pie.

"Do you like what you see", Pinkie asks? I look at Pinkie Pie, who is now wearing light blue denim overalls and a red bandana around her neck. I'm not sure about the bandana, but the overalls caused me to get another bulge in my own overalls, so I gently nod to not bring any attention to my crotch.

Pinkie then jumps on top of me, and it causes me to fall on my back. Pinkie then looks down and notices my blatant erection inside my overalls. Then for the first time since I've known her, she got a seductive look in her eyes. She goes to my legs and she looks at my bulge.

"Hey Sunset, do you wanna play trains?" As soon as Pinkie asked this, I was confused, but then she unzipped the fly of my overalls and pulled my penis out. Pinkie looked at my penis with fascination, and her body started to show that she likes it. "This little whistle must have a lot of steam built up inside Sunset. Let me help you get it out."

"Go for it", I say. The thought of Pinkie doing anything with my penis at this point gets me even harder, and now my penis looks like it can explode.

"All Aboard the Choo Choo train", Pinkie says with enthusiasm. "Next stop, Creampie City." As soon as Pinkie says this, she starts rubbing my penis with both of her hands. I softly moan in pleasure to this action. As Pinkie continues her motion, she starts saying, "Chugga Chugga Chugga Chugga, Choo Choo!" It's a repeated motion and sound, almost as if she's pretending to drive a steam train.

My mind goes to my time in Equestria, where steam trains were our main form of transportation, and suddenly my fantasy turns into Pinkie and I driving a steam train together with the two of us in the engine. As Pinkie continues her actions and sounds, my body tenses up and I start moaning louder.

While probably sensing that I was ready to explode, Pinkie removes her left hand from my penis and she starts stroking really fast with my right. Her train sounds also going faster with every stroke. Soon, she stops saying "Choo Choo" and just repeats "Chugga" over and over. Faster and faster she goes.

"I... I'm about to blow, Pinkie", I exclaim!

"Do it. Blow the whistle loud", Pinkie exclaims back!

"CHOOOOOOO CHOOOOOOO!!!!!!!!!!!" After saying that, I proceed to cum all over Pinkie's overalls and bandana. Soon enough, Pinkie slows down and I release the last bit of my seed. I pant as Pinkie licks the semen from her hands and my penis.

"Wow, that was quite the load, Sunset", Pinkie says. My body starts to give out on the couch, and Pinkie goes to my ear. "You sure are quite the steam train." Hearing this causes me to blush more than I already am, and I notice that Pinkie has a blush too. This was likely her first time doing anything sexual, and I think she enjoyed it. She then gets a towel from my kitchen and dries everything off, which is more than what I could do.

After Pinkie cleans herself off, she then changes back into her puffy skirt and tank top, before putting the overalls and bandana back in her backpack. She goes over to me and helps me back up to my feet.

"Thank you for that", I tell Pinkie.

"No, thank you." I look at her and I pretend to be confused, so I could understand what she meant by that. "Thank you for the fun time. I never had anyone else explore my train fetish before."

When I hear her say that, I turn from forced confusion to legitimate surprise. The fact that Pinkie just admitted that to me is surprising, but it is Pinkie, so I suppose it shouldn't be that surprising. Afterwards, Pinkie starts preparing to head out.

"Where are you going", I ask?

"I got some cakes to bake for the first day of school party", Pinkie replies. "You'll be there, right?"

I nod and Pinkie says her goodbyes. She exits my apartment and I am alone again. Since I don't have any more plans, I decide to just eat some food and go to bed. I was so tired from the past few days of sexual activity with my friends that any break from that would be nice. I decide to put on my first pair of overalls before going to bed, and as soon as I lay down and pull the covers over, I reflect on the last three days and decide on one thing.

"I want more of it in the future, and I will definitely think about them in overalls for my future tug sessions."

Author's Note

And that's the Mane 6. I wanted to get this out sooner, but I never had a concrete idea on what I wanted to do for Pinkie. With that said, these sexy overall adventures aren't done yet, as there are still characters that I want Sunset to interact with to some degree. Thank you for reading up to this point. :)
