There’s got to be a way to trot into the Post Cutie Mark Research Library between classes without feeling like everypony knows what I’m up to.

“Come out to the library,” she wrote on the note she slipped me. “We’ll have a get-together at the group research tables in the back. It’ll be a great time.”

One of these days my eyes are going to get stuck rolling around in my head at Moon Shadow.

So here I am, pushing open the door and stepping my way through the vestibule while the assistant librarian heads out for lunch. We exchanged nods in passing but I don’t expect he remembers my name any more than I remember his.

….”Scroll” Something, I think?

I’ll remember it eventually.

But here I am, passing the main desk with the expected, “Back After Lunch - Help Yourself To The Stacks” sign on display, just where it should be.

Maybe there’s something to this whole, “punctuality” thing I should have a re-think about.

The Hollow Shades PCMS Library is something worth taking your time in. Its main hallway’s vaulted glass ceilings give an unrivaled view of Luna’s night skies, even in the worst of weather. And so much work was put into lighting placements - enough to make echo navigation unneeded since it would disturb everypony, but also to not make the glass be a mirror when trying to see the skies.

Every year the Optics And Sonics classes are challenged with finding shortcomings with the design, documenting why it’s not worth keeping, and how to improve it. Two years ago the class came up with a system to focus Moonlight into glass tubes providing indirect lighting accents from the inner-roof line to the double-sub basement. It was pretty interesting when I read up on it. They used a set of eight mirrors to collect Moonlight into a specially-formed glass collection shaft that then fed down and into the main building.

Only problem was their Saberhorn who pulled two All-Day Back-to-Back cram sessions to get everything ready for the final grade. The spell he used on the mirrors to track the brightest object in the sky and reflect that light into the main collection tube worked as intended…

Both at night and day.

On the bright side, if you’ll pardon the pun, the resulting glass slag made for an interesting art glob that’s still on display in the Materials Sciences department.

I headed to the right-branch walkway, past several tall shelves, around-back of the stairs to the second floor, and found my way to the semi-open group-research alcoves. It was a wonderfully intimate area with attention given to comfort and quietness. A half-dozen round tables around the perimeter with matching curved bench seats, each carved from a single stone, ready for groups of six to collectively tackle any project. In the center of it all was a ball-tipped triangular rug with three triangular wooden tables at each point. That design allowed for triumvirate discussions in order to complete any research with as much clarity as possible.

“Sit at the table with a paper covering a book so your back is to the entryway.” Again whatever Moon Shadow had planned better be worth it.

Ahead and to the right was the table; obvious piece of paper where I would need to sit, it looked like. So, easy enough, I walked over and slid along the curved back until I could see Moon Shadow’s hoof writing in the corner of the page.

She’d written, “Turn Over” in the lower-corner, with that cute “Corner Of The Paper Folding Over” illustration foals draw to go along with it.

I just took the paper, flipped it over, and read the last instruction.

“Don’t Move.”

I couldn’t help it! Normally you don’t have a pair of wings wrap around your thighs when you sit at a table, so I flinched.

“MMmmmmm! Glad you made it, hun.”

“Shadow?!” Her instructions didn’t say “no talking”. My head whipped around, ears swiveling, hoping nopony was nearby. I hissed, “What the buck are you up to?”

Her breath across the inside of my thigh gave half the answer; the other half was an open-mouthed “LLAAHHHH!” as her tongue flowed along the same path, right before her lips covered the base of my sheath and slurped on it. It was the most unnerving experience, seeing Moon Shadow’s eyes and tongue only peeking out of the shadow under the table.

The control she had over her Cutiemark power was only rivaled by her kinky uses of it. One of her kinks, a deeply-held one, was feeling my cock grow from barely a button to full flare in her muzzle. Another was sex in barely concealed locations.

We found a LOT of ‘Barely Concealed Locations’ over the last five months.

“Shadow, you… this is… Sweet Harmony, you're a whorse for cock, aren’t you?”

Not hearing anypony in the vicinity I finally look down in time to watch Moon Shadow’s face materialize out of the under-table darkness, eyes sparkling with mischief and self satisfaction. The only answer she was willing to give me was a double eyebrow waggle and a little laugh before closing her eyes in hungry bliss, lips covering the end of my sheath so my dropping cock had nowhere to go but along the path of her tongue.

My breathing got a little louder as her wings squeezed my hips, pulling us tighter together while her head turned slightly right to left. She could still get out a nasal, “NNNNN!” of pleasure, so I knew about where I was in her mouth. I might not attract any attention by looking around, but the sounds she made’ll only get louder; then it’ll start a feedback loop making me get louder feeding her vocalizations.

Since her head was lifting back to keep from choking her with the flare, I gave her ear a light wingtip flick to get her attention so I could explain the situation.

I could feel her lips purse as those eyes opened, very annoyed, but I got her attention - at least enough to half-whisper, “You need to be quiet. If the librarian comes–”

Annoyance turned to outright angry defiance as she YANKED with her wings and hooves while shoving her head down, spearing my still filling cock to the back of her muzzle. What she was doing screamed volumes about what she thought about getting caught like this.

Her eyes closed tight in concentration while her head angrily twisted right then left as she bobbed deeper, skewering her face, getting her lips closer to my sheath - not making any closer progress since my cock was still growing to match her efforts. With each lift up her grunts of pleasure were switching to annoyance.

She paused with the crown still at her lips, re-opened her eyes, staring daggers at me, like this was my fault somehow. I got as far as inhaling before telling her to not hurt herself when she yanked herself down with her wings, spearing her throat with my cock, finally and for the first time.

What came out of both of us was a combination of grunts and gurgles and grunts and sputters and under-table panicked wing scraping. I couldn’t help myself and grabbed her head, shoving hard behind her ears to lock her into place. She thrashed and head twisted like before, but this time it was with wide-opened eyes in stark reactionary panic. Her wings thrashed, thumping the underside of the table while her front hooves grabbed my legs, undecided on pushing away or locking herself down.

My head pointed straight up, loosening my vocal cords so I wouldn’t screech anything, feeling my cock twitch in that last warning I get. Shadow felt it too, pulling harder then went stock-still, swallowing on the flare, feeling my cum pour down her throat.

OH! She’d been trying to get to this point for the last two months - getting me to cum in her muzzle. But adding to it all finally getting my cock down into her throat enough to hold off her breathing? She’d wanted to do that so badly now; practicing with whatever she could get away with that could be explained away.

For instance, did you know that there’s a farm two towns over from the Library that grows some of the biggest carrots?

Moon Shadow found out.

Her head finally flew back, hacking and gasping for air, coughing and thumping under the table as she inhaled throat slobber and cock juice.

“Everything OK back there?”

Oh, Humping Harmony! The librarian was ba–

“SCROLL KEEPER”! That’s his name!

I looked down just as the last of Shadow disappeared under the table into the dark again. Even right above her I couldn’t see her! That bitch was getting really good at hiding.

I quick-grabbed the book on the table with a hoof, opening to a relatively early page. Just gotta stay calm. I can bluff my way through this. Sure I can! “I’m all fine now, thanks. Just read something scary is all. Very scary chapter. Just getting it locked down in my head. –how're you?”

Turning my head I finally spotted Scroll Keeper peeking around the corner, all curious looking. He let off a small Batpony screech in a very refined dialect and his look changed to one of severe confusion. “You’re reading ‘Echo Location & Theatre Acoustics’ by Limelight Candle and found something in it, “scary?” Nevermind the look on his face, I could practically hear the arched eyebrow on the far-side of his face in the timbre of his voice.

“Well, sure. I mean…” OH-CRAP! OH-CRAP! OH-CRAP! OH-CRAP! “It’s not every night you read about how poor construction techniques can shake apart a theatre when they sympathetically resonate with the interference pattern from the vocalists’ pitches. Right?”

I could almost feel a bead of sweat forming under my mane as we looked at eachother, staring each other down, hoping he’d swallow that line.

C’mon! Swallow it!

I refused to breathe while Scroll Keeper slinked away; I could tell he knew something wasn’t right but didn’t have anything to justify investigating further.

Which worked out just as well since I flinched and looked down again. There was Moon Shadow’s smirking face with my cockhead in her lips like a pacifier. “You ok?” I asked sarcastically. “Looks a little tight under there.”

She pulled my cock half into her muzzle then back out with a ‘pop’ before she answered back saucily. “Soon as you're (Ahem!) back in my bed I'll show you just HOW tight (Hmm!) I am under here.” At least she had the temerity to blush some before she finished. “Sorry. Little hard to talk with all that tasty cum swimming in my throat, you know.”

“Why wait?” I fired back quietly. “I don’t think the Librarian’ll be back anytime soon after that.”

“Because,” she told me like I was a failing student in her class. “In about five minutes the next wave of ponies comes in and I don't want to share you just yet.”

Ok, that got my ears to perk up hard. “--Just Yet?”
