Time had passed by a bit slower than usual for Spike today, that with how the school day began for him and Twilight. It's been, what, six and a half hours since the school day began? Seemed about right. And nothing like the advanced world of science to calm his and Twilight's nerves.

The last hour of his day, like many others, involved a figurative shitload of chemistry among other things, especially with their teacher Dr. Hooves, who, despite being a perfect fit for these types of scientific studies, was a bit too devoted to it. As in he spent about 95% of his time at the school thinking science thoughts and doing science things. The good doctor says his love for science began from some kind of "odd and traumatic event", but he never bothered to explain what that event exactly was.

Spike didn't know what to think of the day, as he rested his head on his desk in a feeling of self-enforced relaxation. It was his first day of legitimately being 18 and of adult age, after all.

"Sorry I'm late..."

And sometimes it truly felt like he was already given a gift of something, as he saw and heard Sunset Shimmer arrive a bit later than usual, rocking those leather leggings like a beautiful rebel. No wonder the class felt less hot than usual. Not only towards the ever-growing feeling of desire towards Sunset, but also the slowly increasing tightness down under.

"Oh, it's quite alright, Ms. Shimmer." assured Dr. Hooves. "You were only off by 12.4 seconds, and in my standards, it's an acceptable tardiness."

"Uh, thanks, Doc." Sunset hesitantly responded, while in a state of minor relief.

"Now-now, just... take a seat, and we can begin." Dr. Hooves directed Sunset towards her seat.

While he shared the same class schedule as Twilight Sparkle, this was the only class in which the two of them were practically on opposite sides of the classroom. A bit of a disadvantage, as he thought about, since he usually gets help through some of the mind-scrambling problems. Didn't help that one person sitting next to him was a mess of bright neon blue and white who spent almost all of her time "wubbing it up" with those headphones.

Twilight, on the other hand, was seated to the right of where Sunset was assigned her seat. Seemed like good organization, since the two of them really have hit it off as friends, even after the last couple of supernatural disasters within the school.

Spike couldn't help but look on as Shimmer took her seat next to Twilight. He was in a state of focus, as the often-entertaining and active lecturings of Dr. Hooves faded from his mind. He was no longer thinking about the variety of ways red and white blood cells are used; all on his mind were the curves on Sunset Shimmer that made the blood rush down his body, into certain appendages in the lower half of his body.

Just thinking about Sunset's body gave Spike the sweats, as his hands lightly quaked in arousal. He felt anxious, just deprived of something, almost thinking that Sunset was tempting him.

The outline of something thick became clear in his pants, and the partly-human couldn't help but reach down and begin to rub himself deeply, below where he rested on the desk he sat at. While he tried to settle his raging dragon-born mass, he scouted the room around him; the classmates grouped around the room were completely occupied, either by the interesting fascinations of acids and cells, or by something of their own personal entertainment.

“No one's looking.” rang inside Spike's mind. “But should I?”

Spike looked back towards the right of the classroom; just staring towards Sunset's luscious leather legs made his bulging hard-on throb harder as he gazed on longer.

Dr. Hooves didn't happen to notice much until then, in which he grew confused by Spike's moans, almost mistaking them for him being restless; the lack of activity in Spike's behavior drove the doctor away from his daily lectures mid-paragraph. “Spike, i-is there something wrong?” The curious and confused teacher asked.

“I'm fine.” Spike whispered back, fighting back any pleasurable spasms to avoid suspicion from anybody.

“Are you sure?” rang Twilight, from across the room. Her sisterly instincts had her on the edge of her worries.

“I said I'm fine.” Spike sternly responded, almost feeling too gravely interrupted.

“...Very well. Back to the drawing board...” Dr. Hooves carried on with expressing his knowledge to the class.

As his composure slowly decreased from the brief bit of concern, Spike's left hand went almost on autopilot, as he tried to hide his pleasure from any bystanders. He looked back towards Sunset Shimmer one more time, his eyes locked onto her from the waist down. By god, those tight and shiny trousers were doing a number on his imagination. Spike's mind was clogging up with dirty thoughts, to the point where he couldn't resist any further.

Slowly, his self-pleasuring hand gripped his zipper and forced his fly open as quietly as possible.

“This is fucking risky...” Spike mentally told himself, feeling a little bit of hesitation towards what he wanted to do. However, the leather beauty he had grown towards resulted in a cause-and-effect in which the urges were too much for him to resist.

Spike's moderate length slipped out through the opening the zipper left, left free to the open, although under the desk. He slowly began to rub his throbbing erection, calmly trying to prevent as much noise as humanly possible; he didn't want to get caught with his cock in his hand, for sure. After all, there was absolutely no going back, no backing down; even with the risk of getting caught, which seemed quite low, but probably not low enough for him.

Thankfully, the desks designed for this class block any view from the left, right and most of the front (although there is a bit of an opening at the top), and it would be hard to notice from the back. So for several of the people in attendance of the class, there was no noticing Spike's go-to hand doing anything, but rather he was resting, in a way.

Although it's a bit creepier if you were seated where Sunset was, because Spike's line of sight was all but pointed directly at her. And it started to make her uncomfortable again.

Shielding her sight away from the frisky serpent-like human with a notebook, Sunset Shimmer looked towards her tablemate for help to combat the creeping feeling. “Uh, Twilight?”

“Yeah?” Twilight asked, at full attention.

“You happen to notice anything off with your buddy over there?”

The purple-tinted girl looked beyond Sunset's head, towards the thousand-year stare of Spike's burning into Sunset's line of direction.

“Probably the birthday blues.” Twilight hypothesized again, not sounding 100% sure of what she's wondering. “Adulthood takes a toll on us all. You should know that, Sunset, given the last few years.”

“Hardy-har.” Sunset let out some sarcastic laughter, making it clear that she's more focused on the problem on the other side of the room than the 'she-demon' business she no longer wanted to hear about again. She then spoke back up, no holding back on any minor yet whispered vulgarity. “Twilight, he's bugging the shit outta me; unless you have some sort of plan, I suggest you try figuring it out for yourself.”

“I suppose that's the first I've gotta try...” Twilight reluctantly responded; it was her responsibility to keep track on Spike, even after he's an official adult.

But right now, the poor and perverted drake of a half-human being was lost in his own private desire, as he quickened his pace on the hand rocking the cock up and down. He wasn't quite audibly panting, as to avoid any attraction from a student near to him.

He has grown desperate. He wanted to get his hands on Sunset Shimmer, and to feel her tight leather clothing up and down, in a masturbatory case of absolute and utter lust. Fuck Rainbow Dash. Fuck Rarity. The prize in his eyes looked much more succulent.

Up-down-up-down...

“Fuck. Fuuuuuck...”

His lefty stroked him faster and faster with every second closer to satisfaction. His arm was clearly getting tired as the greatly well-deserved fap drew out longer. Just one hard rub-down was all he wanted to get through his day, especially ever since he fell in love with Sunset's changing sense of fashion. The lycra-like material made her a big target for loving, and the thoughts in his head raging about her continued to drive him closer and closer to a big finish, until--

“Spike, we need to talk about thi--”

And then it released. Thick strings of cum unleashed itself, firing itself right out of Spike's engorged cock, in a moment of explosive relief, through the opening of the desk...

...and right onto Twilight. Right all over her skirt and legs came the loaded bullets from a groin-area shotgun, splattering her whiter with every shot. Spike had blasted at least eight ballfulls of semen, and the unfortunate target was within point-blank range of his seed-spreading orgasm.

Just then, the entire laboratory was completely silent; even the teacher who could often never shut up about science stopped in his tracks, having heard the splurts and splashes from behind him, and turned around to find the commotion that had completely stopped the class.

Twilight looked down as her jaw practically got stuck in an open state, all feeling of worry replaced with pure shock and awe.

“Aa-a-a-aaa...” Twilight moaned, absolutely horrified by the realization that had hit her lap.

“Oh my.” Dr. Hooves looked amused by the circumstances, a bit opposing Twilight's emotions. “Either Spike's got a special somebody on his mind or he really loves science.”

“Uhh-h-h-hhh, D-D-Doc?” Twilight strained some words out towards the expert.

“Yes, yes, go ahead; I think we could all use a break after... that.” Dr. Hooves was much oblidged to let Twilight go to whatever could help her.

The traumatized book-smart girl then took off running, most likely for the nearest bathroom to clean herself in.

“Dammit.” Sunset muttered to herself, knowing it was herself to blame for getting Twilight to come to Spike, and witness him come. “Sorry, I need to go.” With that, Sunset followed after Twilight, willing to make up for throwing her head-on into an mind-shattering incident.

Spike was indeed as startled and scared by his own actions, as he quickly zipped up and stood up.

“I need to go sort this out, too!” Spike shouted in a hurried tone, as he dashed off into the hallways as well, also looking for the nearest bathroom.

All Dr. Hooves could do was look on and speak. “Be careful out there! If there's any statues moving around on their own, take my word: don't blink!”

Don't worry, Doc; that's definitely not on the mind of anyone involved.

Author's Note

If there was a way I'd rate myself from 1 to 10 on fanfiction writing, I'd say a reasonable 5. There's certainly a lot more people who get into more detail. My fics just seem rushed, even when I'm trying to put some detail in.

Well, I hope you enjoyed this chapter. The third and final chapter will be around the corner.
