I woke up at around 5 in the morning. It's a bit early for me since the sun isn't out, but I am going to see Rainbow Dash this morning, who asked me to exercise with her one day this week. If the sun was out, I could barely keep up, actually, I'd sweat. I quickly get dressed in a tracksuit with a t-shirt underneath. Since a tracksuit can get a little sweaty, I go through my closet and pack my overalls in my bag. After packing and combing my hair, I see Rainbow Dash just outside my apartment, exercise bag in hand.

"Hey Sunset," she called out! "Are you coming or not?"

"On my way", I called back. I quickly exited my apartment and went out to see Rainbow Dash. She had her blue tracksuit on and she was near her car. She can run everywhere, but she got her car for my sake. We get into the car and we drive out to Canterlot High.

Canterlot High is usually closed, but the track and field isn't, making it a great place for exercise. We proceed to jog a few laps around the track, before Rainbow Dash went into a sprint.

"Wait up", I called. By then, she was already half the track ahead of me and I had to start sprinting to keep up. However, I just didn't have the stamina to keep moving at the pace I was going, so I had to stop to catch my breath. I was panting, sweat dripping from my forehead, and the sun was just starting to rise. Rainbow Dash eventually came up from behind me and tapped on my shoulder.

"What's wrong slowpoke", she asked? "Tired already? We barely got started." I was wanting to respond, but every single word I said was followed with a pant. I couldn't even complete a sentence before Rainbow Dash stopped me.

"Yeah, just go ahead and head to the lockers", she said. "Take a shower, put on some clean clothes, and I'll just exercise from here."

I took Rainbow Dash's advice and went to the lockers. Gym lockers aren't the best thing in the world, but at least they have showers. I took off my tracksuit and t-shirt before turning on the shower. It was a pretty open area with a lot of space to move around. From what I hear, these are normally filled with people, but I've never taken a gym shower in my life. I looked down to see the reason why. My penis, thinking about being around a bunch of girls in all shapes and sizes, started getting erect. I quickly had to think of another topic in hopes of Rainbow Dash not walking in and finding out my secret.

Eventually, I was able to wash myself and I turned off the shower. I got a towel and dried myself off, removing any sweat and water that's dripping on my body. I looked at my t-shirt, before deciding it was suitable enough to wear, before putting on my blue denim overalls. I sat down at the bench and I rubbed my crotch. I was getting aroused in my overalls, I suppose I have enough time for a quickie. Well, I thought I did.

"Wedgie!" As I heard this, I suddenly felt the straps of my overalls pull upward, causing me to hang for a little bit.

"H... hey! What's the big idea", I asked? I turned my head and I saw Rainbow Dash, holding the straps of my overalls with a grin on her face.

"You should have thought about that before you chose that outfit. I usually never get a chance to do this." Rainbow Dash then told me more than I ever needed to know about how she wanted to give wedgies to her friends, and how my overalls were perfect at doing that. At the time, I was too focused on my own issues to care about hers. The denim sinking into my vagina and my penis getting erect in the overalls. The bulge must have been noticeable, as she quickly unzipped my overalls and fished in the fly, before pulling my penis out.

"You have a penis, huh", she asked? I could only nod. "Well, let's see if so can give this thing a Sonic Rainboom. She proceeded to stroke my penis from behind, before using her free hand to put her hand inside my overalls. Rubbing my stomach and breasts along with my penis, I could only moan softly. She started seeing that I was into it, and she started going faster. Faster she went, her hands reaching speeds I could barely handle. I was so close to reaching climax. Going, going...

And then she stopped. Before I could reach orgasm, she stopped. She proceeded to look at me, and I knew that she knew, that I was right where she wanted me. She proceeded to pull me up by the straps, before taking me to a nearby hangar in the locker room. She pulled up my straps and hung them on the hangar. The denim overalls snug around my crotch, rubbing against my vagina, and my penis still in display.

"That's better", she said. "Now I can truly make you reach a Sonic Rainboom." As she said that, she started to stroke my penis again. I was helpless, unable to resist the pleasure. My penis got stiff and hard as Rainbow Dash stroked it. The denim digging deep into my vagina, and the straps hanging on by a thread. I moaned loudly, and Rainbow started stroking faster. Faster, faster, almost there... Ah!

I came all over the floor of the locker, with a moan so loud I bet the people nearby the school could hear me. Rainbow Dash looked at my cum after I finished, before giving a smile.

"You sure were pent up, huh Sunset?" I knew I came twice yesterday and the day before at least, but like before, Rainbow Dash offered something new and exciting for me, so I couldn't resist letting out my seed. "I was hoping you would last longer. Oh well."

Afterwards, Rainbow Dash proceeded to help me down from the hangar, and she checked on the straps of my overalls.

"Still holding strong. These are pretty resistant compared to panties." I nodded in agreement, because how could I refuse to agree at this point? I was panting, I was tired, and I had just came. "Let's get you home."

Rainbow Dash cleaned up my penis and the floor before zipping up my overalls. I got my bag and Rainbow Dash started up the car. I got inside and she drove me home. After we got back to my apartment, I got out the car and was about to head inside, until she lured me to the driver side window.

"Next time, I want you to do that to me", Rainbow told me. The thought made me blush, and I got a blatant bulge in my overalls again.

"Oh, okay", I responded. She pointed down at my crotch and I looked down, seeing the bulge again. I decided to just head inside before Rainbow Dash drove off.

Once I got inside, I took off my shirt and only had my overalls on. I sat on my bed and took a quick fap break, before going to sleep. I didn't cum from the fapping, but it felt good, so it didn't matter. I fell asleep in my overalls for a few good hours afterwards.
