A mysterious pixel cube appeared, staying still until another pixel cube appears. One after the other, they slowly form in random directions until each of them form a shape of me. Once all of the cubes changed form, they turned into my skin color. My eyes were shut, but I opened them before slowly moving one limb and another until I can control my own body. After that, various colors surrounded by body in forms of shoes, jeans, and a muscle shirt. When I looked around, I saw myself in only a room filled with matrix-type squares, and below me a neon blue floor.

"Ok, what's going on?" I called out. "HEY! DOT! WHERE ARE YOU GUYS!"

No answer. No response. Until a few seconds later, a voice of Dot answered before explaining that I'm in a simulation training room. In fact, everywhere in a computer world is indeed a simulation, and anyone inside is recognized as a program. Little did I realize is that she is indeed on the same program, and so we're the other mares while Computer Graphic manages them. She also mentioned that almost every program is meant to have generic actions such as walking and eating, which is why she managed to type a program of me with additional actions. Even though the process took a little longer than usual, it was worth it at most. As for right now, I am possibly known as a casual program, but I felt like something was still in me even when I'm in a different world or an unknown organism.

Wait, even if I'm a program, can I still fuck?" I wondered.

"Wait! I almost forgot!" Dot shouted before typing on her keyboard quickly, and as she typed, I suddenly froze still. As soon as she finished typing and pressed "Enter", I was able to move again.

"Sorry about that. I had to load up your real-world abilities such as your sex experience. It was hard to put into your program, but we figured it out." Dot explained.

"Oh great. THANKS!" I responded.

"I'll be out in a minute." Dot spoke while typing another program." In the meantime, try walking a few steps, or moving your limbs."

"That's it? All I have to do is move my limbs?" I replied.

"Don't worry, Mojo. The mares and Master Graphic are putting on some finishing touches, so just do something."

I shrugged to myself and started walking around the room. Then, I decided to stretch my limbs and do some combat moves to prepare myself.

"Who-o-o-oa! Mr. MMA over here..." someone appeared, calling out and making a joke.

I paused and turned, only to see a neon pink and white earth mare wearing a short red jumpsuit and blue glowing combat-like heels. The earth mare saw my reaction and giggled before doing a little turn, showing her curves in front of me. What I noticed about her jumpsuit is that the bottom of it was short shorts, slightly showing her ass cheeks.

The earth mare introduced herself, flaunting her curves in front of me. "Name's Pixel Sprites. I heard you can fuck really good..."

"So they say..." I replied, watching her.

"Which is why..." Pixel walked and stood close to me with a hungry look in her eyes. "I wanna be the first to test you out..."

"How?" I asked, slightly tilting my head.

Pixel quickly leaned close to my ear and whispered with sexual enthusiasm. Here's your mission: Watch as I ride your cock in under three minutes... and all you have to do is endure me."

"Okay. I accept your challenge." I nodded.

Suddenly, Pixel did a flashing gesture with her fingers, zapping me down to the ground. I tried to get up, but she pushed me down to ground and started rubbing her body close to mine, with her crotch already heating up and making me erect. She wasted no time getting all of her jumpsuit off until she was fully naked, which made her body just about ripe to get. But then, she strippeped off all of mine until I was the same, and my member stretched and pointed upward under my jeans. Pixel licked her lips, humming with a little orgasmic moan before coming close to it.

Once I was hard enough, she stripped off my clothes, got down on her knees, and gave my member a little suck. Pixel worked her tongue around the tip and pushed down a few inches.

"Not bad..." Pixel smirked, feeling slightly impressed. "But this where the real fun starts now..."

Pixel started bouncing in a slow speed. At the same time, a clock appeared above us, reading "Three minutes, Countdown starts Now! Good luck!" before turning to an hourglass. While the hologram sand started dropping from the top to bottom little by little, Pixel moved her hips around in circles, grinding my prick smoothly. It went on for a minute and a half, and I wasn't close to cumming . Her body was something to really get my hands on, and I had to pull her close and was about to thrust upward, but...

"Whoa, black horsey! Just relax... This is an endurance challenge, remember? Save it for the other mares, ok?" Pixel put a hand on my chest, calming my beast mode down. Although it sucks for me to wait around, I nodded to let her control again.

The hourglass read "One Minute Left!", and Pixel stopped at nothing to try and make me cum hard. In fact, she had one little trick up her sleeve. She got off and turned herself around, planting her pussy on my face. After facing my prick, she abruptly started sucking it from tip to almost the whole base.

"Lick it..." Pixel demanded, splitting one of her ass cheeks. I startled licking her pussy thoroughly. She imagined that my tongue was like another cock good enough for her to play around with. The battle of wits intensify as each of us is teasing one another, and we weren't close to cumming yet. As Pixel started teasing my cock, I did my absolute tongue from clit to entrance, rolling it around in both places. We both moaned slightly and paused for a while, but we continued pleasuring each other.

Back at the Computer Classroom, all of the mares, including Graphic, were watching the action from the imaging machine's hologram. Although some of the mares were typing additional programs to load into the simulation, others stopped and watched in order to slightly touch themselves, including Hallow Touch and Dot Dash.

"Oh my Gods, that boy... and his cock... he looks... too sexy... I just gotta... have him, but..." Hallow thought as she was rubbing her crotch.

"Wow. This guy is definitely a freak! And, I've never thought of a stallion fucking me, or me riding one, like that. Then again..." Dot thought as she was hearing the sounds and biting her lip.

"Something just keeps standing in my way..." they both said in thought.

***

Meanwhile, we paused and got off of each other after several seconds, but Pixel cheated by wrapping her hands around my member and stroking it, giving the tip several licks before sucking again. "Are you gonna cum?"

I held on for a while, despite having to be pleasured twice. But, Pixel stopped sucking and crawled on top of me in order to tease my cock yet again. She landed her marehood comfortably on the base, and started rubbing it up and down, moving her hips in slow to moderate paces. We stared at each other with lust-filled eyes, as if we were this close to fucking. Then again, she was the only one that this close to having to fuck me, and I couldn't do a thing except watch.

Are you gonna cum for me?..." Pixel showed her slutty lust face as soon as she buried my member inside her marehood, and with her hands on top of her head, she quickened her pace, bouncing with her ass up and down. I grabbed on to her ass cheeks and held on for the ride, despite the fact that I might be on the edge of release.

"I'm cumming!" Pixel warned.

"Me too!" I replied, with my hands still on her hips.

After all of the hourglass sand reached the bottom and the buzzer sound, Pixel slowed her movements down until she paused, landing herself on top of me, with her head on my chest.

Back at the classroom, all of the class and Graphic watched, impressed with how I did. Even though the lust has gotten into them, they, still having tricks up their sleeves, planned and decided to wait until later to surprise me. Dot couldn't believe that hearing a mare moan like that was all my doing, but as far that goes, she would have to do some work and experience it for herself. In the meantime, she would have to try and catch more proof. Suddenly, she had an idea.

"Master, permission to enter the simulation?" "Dot and Hallow called out. They quickly looked at each other.

"Oh. Ok then." Graphic permitted, despite having a small ounce of shock in her head. She has a thought of having to go there herself, but the two professional mares beat her to it. "He's all yours."

Once Dot picked up her cane, she and Hallow climbed themselves aboard and made their way to the machine, and once the mares did the work, the auras around them spun until they disappeared.

"Hold it right there!... Nobody passes by the master of Triple X City!... I won't give up just yet...I still have a little something I know you're gonna love..."
