I made the mistake of using Luna's mane and tail shampoo.

Turns out one perk of being the Princess of the Sun or Moon was a personalized set of shampoos and conditioners, specially made to deal with the challenges of that magically charged, eternally flowing hair. I did not know this. And Luna's dark, night-themed bathroom decor made it a little tricky to see labels...

Long story short, even after several extra rinses, I left her chambers with my short brown hair sparkling.

Not brightly, mind. I wasn't going to dazzle anybody or blind someone with a laser lightshow or show off the Big Dipper in my hair. No, just every few seconds a point on my head would gleam like a star in the night sky. And I was annoyed because it made me look like I had the most fabulous dandruff problem.

I must have been quite a sight, descending the stairs of her tower in nothing but my shoes and one of Luna's towels wrapped around my waist, my other clothes held in a bundle under my arm. The early-morning guards assigned to the bridge connecting the tower to the rest of the castle certainly seemed surprised. The two armored stallions didn't move from their posts, but their eyes did bounce between naked me and the tower and back to me, attempting to draw the obvious connection.

I thought about saying something with my power to cover up the fact that I'd just had a quickie with their lunar goddess, but I was still a little antsy and grumpy and so I decided to leave them be. Besides, if they were professionals, they wouldn't spread rumors about who was meeting the Princesses at whatever hours.

My plan at that moment was to march back to my room, figure out how to dress myself (since right now I only had the one set of street clothes and the suit from Fancy Pants), and then head to the kitchens for breakfast. But I was derailed by a certain Prince as I rounded a corner and we made eye contact from across the next hall. I wasn't exactly in a mood to figure out how to solve Prince Blueblood's problems, and kind of hoped the preppy royal stallion would leave me be. For a second, I could see something of a grimace on the Prince's face, giving me hope that he would go another way. But then he seemed to summon some courage and march straight towards me, so I braced myself.

Blueblood walked over and stood in front of me, his blue eyes looking my half-naked body up and down. "Pascal..."

I had flashbacks to when the masculine stallion had literally presented himself to me Saturday night, and prayed I wouldn't see a repeat. "Yeah, Your Highness?" I said, trying to keep the edge out of my voice.

His eyes lingered on the lunar insignia on the towel, and I could see the question dancing behind his eyes. But he ignored it for the moment and said, "I... wanted to say something, the next chance I got."

"Shoot," I replied. This seemed to be going better already.

Blueblood took a deep breath and sighed. He took a moment to make sure no one was nearby to eavesdrop, then looked at me. "I realize that my actions that night put a lot of unwelcome pressure on you, and I wanted to apologize for that. I was... under a lot of stress, and I somewhat foisted a few personal problems in your face. Among other things."

No kidding, I thought.

The Prince's chest seemed to puff up, as though some weight was already being lifted as he spoke. "So I want to be clear that I have no expectations. I've since cleared my head. I simply ask for your forgiveness and understanding."

I frowned and shook my head. "Look, Prince. I exploited your fundraising party to... to take in some of the high society life and... and spread my own brand of 'normal.' I'm the one that owes you an apology, frankly."

"Then let us consider the matter squared!" Blueblood decreed, raising a fist in solidarity. Then he leaned in with a bit of a smirk. "And besides, if it has the same end result as last time, as far as I'm concerned you can 'exploit' my events whenever you like!"

Ah, right, I did sort of create a big ol' normalized orgy and walk out, didn't I? I had wondered about the effect on the fundraiser and Blueblood's reputation – looks like it was positive.

Another question lingered in my mind. "So are you not really attracted to me, then?" I recalled it was Spitfire's powered-up influence that led to the whole 'confession' in the first place. Blueblood said he'd 'cleared his head' – was that like Rainbow Dash examining why she enjoyed sucking my dick and coming up with 'method acting'?

Blueblood pursed his lips and glanced aside. A bit of color sprouted on his sharp white cheeks. Uh-oh. "Well... I probably shouldn't say."

Dammit. Alright, time to make my boundaries crystal clear with this dude. "Hey. I'm in an open poly relationship, and it's friggin' inevitable I'm gonna cross the bicurious event horizon someday. When that happens, I might be willing to take you up on your 'offer' in a casual – I can't stress this enough – casual manner. But I wouldn't wait every day in the mailroom if I were you. And if you're looking for romance... you should probably look somewhere else."

The Prince's ice-blue eyes went through a number of interesting motions. There was widening with hope and surprise, bouncing up and down my body with nervous excitement, then dropping low with disappointment.

"Just so you know what to expect from me," I said.

He nodded. "I understand." Then he put his hand on his chin and regarded me in a studious way. "So gender is the main barrier..."

I resisted the urge to throw back my head and groan at the ceiling. Instead I just managed a low grumble in the back of my throat. "Look, if you end up using a swap potion or spell or something – just don't ambush me with it, okay? Geez."

Blueblood's eyes widened at the suggestion; I guess he hadn't actually been implying that and I'd caught him off guard. He then chuckled bashfully. "Sounds as though you have experience."

"You have no idea. In fact, your little 'offer' was nowhere near the strangest" – or most mentally scarring, I internally added, thinking of Celestia – "thing to happen that evening."

"I– Wow." He put out a hand towards me, which I awkwardly managed to shake while keeping my towel and bundle of clothes up with my other arm. "Well, thank you for listening, Mr. Pascal. I wish you luck. I've read up on your situation; being an alien commoner from another world will no doubt make things like bureaucracy and finances challenging here, so if you need any kind of favor, by all means write me."

I was surprised. I had only barely started to think about those sorts of things; I'd been stuck in legal limbo for so long. "That's... very generous of you," I said. Why were you never this kind to Rarity at the Gala? my inner nerd questioned.

"It's the least I can do for, well, everything. In public," Blueblood said with another embarrassed chuckle. Ah, was this some way of ensuring that I didn't spread mean rumors about him? More mean rumors than he was already getting, anyway? ...Okay, maybe I needed to take a timeout on the cynicism.

I pulled my hand back and adjusted my towel before it nearly slipped off my body. "Welp, I gotta go get decent, so..."

"Of course, of course," Blueblood said as I hurried by. "Your hair looks marvelous, by the way!"

I winced hard and continued stomping down the hall. "Just– Just don't ask!"

I wasn't sure if Derpy was going to sleep in without me, so I opened the door to our room carefully and slowly. However, I was not expecting what I saw inside.

"Moondancer?" I called out as I entered.

The beige unicorn sitting at the edge of our (otherwise empty) bed looked up from her book (which she was resting against her enormous sweater-covered bosom) with a bit of a start. "Oh, hey!" As I clumsily closed the door behind me, her eyes locked in on my moon-styled towel. "Um... Is that...?"

I looked down. "Long stor– Well actually a short story now that I think about it, and it kinda tells itself." I hurried over to the bathroom and tossed my bundle of smelly clothes inside, allowing me to get a more proper hold on the towel to maintain my decency.

"Y-Your hair...?"

"That is a slightly longer story."

Moondancer still seemed a little hung up on the unspoken revelation. Without looking down, she magically stuck a bookmark into her novel and set it aside. "Y-You and Luna?!"

"Yeah. She'd been very... patient, apparently. And she's way more confident in her sexuality. Think that might be significant going forward." I grimaced as I realized I probably shouldn't kiss and tell, especially when it comes to royals. Moondancer was trustworthy, and it wasn't like I had signed an NDA, but I needed to exercise a tad more discretion with more than just Celestia's problems. "Anyway, what are you doing here?"

"Well, uh..." Moondancer crossed her legs and looked aside awkwardly. "I guess I should start from where we split up. Or maybe... Long story short, Trixie's setting up a sort of magical night for you two. You and, um, 'Derpy.'"

I was taken aback, mostly because I'd been planning to do the same thing. "Really?"

"Yeah. She wanted to keep it as a surprise, but..." She cleared her throat and pretended she wasn't getting a little red in the face. "So after your treatment, the three of us talked for a while, and it came up that tonight was going to be her last night off in Canterlot, and the first night you're non-addictive, so... Trixie was all, 'We have to make this The Best Night Ever!' and started making plans."

Those never turn out well, I kept to myself. I walked over to the closet to survey my clothing options. When I opened the sliding door, to my surprise, there was an extra bag on the floor with more of my old wardrobe neatly folded in it!

"Derpy went back to your place last night to get more of your clothes," Moondancer explained.

So she flew or took the train to Ponyville, visited Lyra and Bon Bon's place, asked for a few extra changes of my clothes, and brought them back up to Canterlot? All last night? "She is just too kind..." I muttered as I picked out a new shirt and pants and hurried to the bathroom.

While I was changing, Moondancer came up to the door and kept talking. "She and Trixie left about fifteen minutes ago! Trixie's taking her out on the town, shopping and stuff I guess, and setting up something for you two in the evening."

Decency restored, I opened the door and squinted at Moondancer. "I wasn't invited?"

She shrugged and stepped back to allow me through. "Well, we weren't sure what was going to happen to you. She figured you might be tired and need your rest. Y'know, so you could save up... for tonight..." Moondancer lost a bit of steam and sort of sheepishly smiled. "It made a lot more sense when she said it."

I mentally assessed my condition. Truth was, I could probably use a little rest today. I'd just finished another round of craziness. I had nearly blacked out again last night. But Luna's quickie left me with a little extra need in my loins that made me antsy. And more than that...

"I kinda wanted to spend the day with her, too, not just a magical night," I complained, making my way towards the bed.

Moondancer joined me as we sat down. "Maybe let Trixie have this one? I think she's trying to get on good terms with Derpy and make sure this polyamorous arrangement starts out strong. It might be for the best."

"Well, I don't have a choice now. Do you know where she went first?"

"Nnnnnot really..."

I rolled my eyes and fell back onto the big comfy bed.

"Though she did want me to tell you to 'be in your tux at the palace gates at 5.' So I guess that's when the 'magical night' begins."

I pinched the bridge of my nose and sighed. "Y'know... It's not like I don't appreciate it, and I have a feeling she's gonna burn a crapton of money doing this..."

"She might have some receipts for you," Moondancer jokingly agreed.

"But, ugh." I threw up my hands and then let them bounce on the mattress. "Maybe it's my male pride, but I'm kind of sick of being dragged along by everyone else's plans! I'm dying to do something that I decided to do, y'know?"

There was a bit of an uncomfortable silence. I momentarily regretted my complaining, but before I could backpedal, Moondancer chuckled nervously and said, "W-Well, you're kind of a brand new state-sanctioned demigod. You're gonna have a social calendar now; not much you can do about that. Everyone will have to be proactive if they want your time and attention."

I tilted my head over to her. "Is that what you think of me?"

She shook her head back, quicker than I expected. "Not really. I got to see you in action, see what you're really like. Most everyone else hasn't yet. It's good they don't think you're a monster anymore, but... it might take more time."

I scratched my chin, scrunching up in annoyance as I felt the beginnings of scraggly stubble already making its return. I sighed. "Whatever. Don't want to sound like an ungrateful bastard. She probably knows Canterlot better anyway, and I hope she and Derpy have a great time. Just wish they'd waited maybe an extra half-hour for me. Guess it's not like they would've known when I was getting back, though..."

Moondancer scooted back towards me and gave me a half-worried, half-curious look. "How did the, uh, session go, anyway? If you can tell me."

Shrugging, I replied, "It was a net positive. I don't think she's nearly as happy with it as I am."

She scoffed. "Well, naturally."

"I mean, I thought we were making much more progress, and then she sorta bounced back this morning. It's frustrating. But I think we made at least one solid step forward. Out of a thousand, maybe, but hey, one."

"That's good. So you think it's working? And she didn't go as, uh..." She glanced meaningfully at my crotch. "...hard on you as last time?"

My grumpy expression probably told her all she needed to know, but I still tried to clarify. "Nearly blacked out again, but at least she was the one who stopped things this time."

Moondancer went silent for a while after that, and not in a very comforting way. Her lips were pursed, and her gaze was fixated thoughtfully between my legs. What in the world was she thinking about in response to that?

"Something on your mind?" I asked.

The student pushed up her taped-together glasses, opened her mouth to form a few different words, then started to chew her bottom lip in a concerned manner. None of it helped my mood.

I sat up on my elbows. "Moondancer? Hey, is the world ending, what?"

"Sorry, just thinking..."

"Abooouuut?"

She huffed a bit impatiently and spat, "Your penis, okay? Your dick. Do I need to spell it out?"

Feeling a little testy myself, I replied, "I'd prefer if you did, 'cuz I'd like to know if I should be concerned for the health of Pascal Jr. here."

Moondancer started and put a hand over her face. "Goddess, never call it that again..."

"Believe me, I didn't want to, but I kinda had to snap you out of your trance there. What are you thinking in regards to my dick?"

She spent a few more drawn-out moments trying and failing to figure out how to say what she wanted to say. This time I waited and let her find her words; this was starting to look too serious for further sass.

"Have you...?" Moondancer began, then restarted again. "Besides Twilight's sperm-cell enchantment, have you had any other magic cast on your... your package?"

I sat up fully now, adjusting the bunched-up sheets beneath me. "No, I don't think so." I paused. "What... What was that enchantment, by the way?" Funny that only now did I think to ask what ol' Twilight had cast on my balls.

Moondancer looked aside nervously. In a quiet voice, she mumbled, "Am I allowed to tell you, or...?"

A fair question, if we were considering the risk that Celestia might grill the answer out of me later. But on the other hand... "I have a right to know," I said. They were my jewels.

She nodded and scooted a little closer. She checked over her shoulders a couple of times as if checking for eavesdroppers; frankly, I did the same. Eventually, Moondancer just cast a spell with her horn and surrounded our heads with a pink bubble of silence.

"We didn't want to do a vasectomy, and we didn't want to make you incapable of producing sperm cells," Moondancer explained. "So what we did was... Your current and future sperm now have a sort of reactionary enchantment on each one of them. When it comes into contact with pony tissue cells, instead of triggering absorption, it throws up a barrier and continues on its natural path."

I raised one eyebrow up as high as I could. "You shielded every individual sperm?"

"It doesn't actually add any mass," Moondancer clarified. "It's more of a... situational quantum barrier. To prevent that specific magi-chemical reaction." She brushed a bit of hair away from her eyes. "I mean, you're the only one of your species on this planet – it didn't seem right to go scorched-earth on your reproductive organs."

"Huh..."

Moondancer dismissed the bubble of silence, allowing us to pull back from our awkward leaning postures. We both looked around, then back at each other – unspoken, we agreed not to speak of this in the open. Celestia had eyes and ears everywhere; Moondancer had firsthand experience with that.

"Anyway, so – your penis," Moondancer segued with an impressive amount of calm. "What exactly have you had done to it so far?"

Thrown off by the tangent, I had forgotten the thread of why this seemed to be an issue all of a sudden. But I did my best to quickly answer. "Well, I started at five-and-seven-eighths..."

Moondancer rolled her eyes a little bit, because of course I had measured it so precisely before.

I pretended I didn't notice that. "The first enhancement, that was a slow process with Twi's magic and Zecora's potions and with a bunch of other surgeons keeping watch. That's the 10-inch dick I showed up with on Saturday. Then the other one was..." I trailed off and closed my eyes. "Oh."

"Photo Finish?" Moondancer continued for me. "When she had her personal assistant cast that growth/aphrodisiac mix on you for a fraction of a second? When your body wasn't completely magically ready for it? When we had to use healing auras because it got all raw and... tender and..." She shuddered at the memory.

I rubbed the back of my neck. "Yeah, that one. I'm guessing you think that's–"

"I'm worried it's not healthy in the long term," she said.

I tossed up my hands and nodded; a gesture saying 'fair enough.' "Got me this far, though."

For a moment, Moondancer just stared off into space, shaking her head slightly. "I can't believe I have to be the one worried about the health of your dick..."

"Why ARE you concerned?" I asked, because it was a valid question.

Moondancer waved me off and sat up a little straighter. "Be honest with me; have you had any problems, any at all... y'know, since that happened?"

I thought pretty hard about that. How could I complain, really? It was a thick footlong salami of a thing now. My sack almost overflowed one of my hands. I couldn't remember the last time I shot a blank. And when I orgasmed, the experience was just nothing short of–

I frowned. "Well, there is one thing."

"Yes??"

I had to scoff a bit at how absurd this situation was. "Well, Dr. Dancer," I said, "when I cum, it's very very very very... intense. The buildup is enormous, and the spasms rock my whole world. 'Volcanic' is the word I keep coming back to."

Moondancer's hand started tapping her generous thigh. She really was very thickly built; that sweater and those loose cargo pants really did a lot to obscure her proportions, which otherwise belonged to a very generous MILF. Enormous milk-sloshing breasts, breeding hips, incredible thighs; she was just one big cuddly–

"–would you say?"

I dragged my eyes back up. "I'm sorry?"

"Do I have your attention now?" Moondancer deadpanned, tilting her head down to peer over her glasses.

I sheepishly looked away. It had been a while since I was so completely distracted – and in front of a pony who was immune to my aura and knew my perversions all too well, no less. "I'm sorry."

Moondancer sighed and repeated herself. "Your orgasms are difficult, would you say?"

"I dunno about that... They're still orgasms, they're great. It just stands out."

She leaned in towards me, and I got the feeling that she was about to deliver the point she was trying to make. "Do you think it's possible that the 'volcanicity' of your orgasms and your tendency to black out might be related?"

I reared back. "M-Maybe? But, I mean, that could also be because I have a shitty out-of-shape body and stamina, and I've only blacked out with Celestia, so it might be just her ravenous–"

Abruptly, Moondancer stood up. "Drop 'em."

I gave up. She had a valid point, and I trusted her. I stood up, unbuckled, and dropped my pants and my underwear in one fell swoop. I kicked them aside so I could spread my legs out. I was already pretty comfortable letting my junk hang out in this room, and Moondancer didn't seem to offended. In fact, the sight of my flaccid dick resting atop my balls on the royal sheets seemed to make her pause. She'd said we could be 'friends with benefits' at the end of Saturday night, but I wondered how eager or committed she really was to that idea.

After taking a deep breath to steady herself, Moondancer knelt between my legs and put her face in studying range – that is to say, almost uncomfortably close to my cock. Her huge sweater-bound breasts pressed against the base of the bed, pooling beneath my thighs. All I could say was, "Uh, got a good enough look there?"

"You may want to look away," she said all of a sudden, and her horn started to charge up with energy.

"W-What?"

"Unless you don't mind seeing your penis transparent with all the blood vessels revealed."

"...Ah." I turned my head away. And just in time; her horn went off and zapped my crotch with a spell that felt like it blossomed out until most of my hips were covered. A faint white glow creeped into the lower edges of my vision. I resisted the urge to look down and just focused on the ceiling. I could imagine what she was looking at, though – a 3D X-ray of my manhood.

"Hmmmm..."

I need to stop trusting these unicorns with my cock so much, I muttered internally. "Are you sure you should be the one doing this?" I asked.

Moondancer gave an annoyed grunt and replied, "At this point, I'm one of the world's leading experts on your reproductive organs. And, um..." She quieted down for a second, which piqued my interest. "I... I kind of know a thing or two about... well... magic and penises."

It took me a couple of seconds, but I had to smirk once I finally put it together. Right, she had implied something to that effect back in front of the stadium, hadn't she? "Something of a solo connoisseur, huh?"

I could feel her hair brush against my bare skin as she turned her head to one side in embarrassment. "Um, are you bothered by that?"

Half-heartedly, I shrugged while still keeping my head pointed towards the ceiling. "At this point, I don't know. But let's just say I saw plenty of dickgirl porn art on my way to the hyper and growth and male-dom and mind control stuff, so I'm kind of inured to it."

"Okay..." she replied uncertainly. Moondancer tugged on the head of my penis with her magic, gently stretching it away from my body. "So... you really do get off to this stuff? I mean, the whole brainwashing thing? Having all that power?"

"Eh. Mind control fantasies of various flavors, once upon a time. Confronted now with a brainwashing reality, Celestia in particular... Not so sure."

Moondancer made a noncommittal "Hmm" and didn't comment further. The magical manipulation of my penis finally ceased, though I could still feel the x-ray aura tingling through my crotch. Moondancer said, "I can see why you might be experiencing a lot of backing up before ejaculation and..." I could almost feel the heat of her blush. "Well, I shouldn't go into too much detail. But let's just say I'm kind of worried about whatever other stallions Photo Finish has done this to. She seems to have a particular preference in, well, cumshots. At least for the others it's temporary."

"Yikes," I said. I was starting to get dizzy from keeping my face held up towards the ceiling. "Well, it still got me through the night, sort of."

"There is that," Moondancer admitted. Her hands pushed against the base of my cock (which felt sore in a way I hadn't noticed until now) and gently cupped my balls. "And it looks like your ability to make semen hasn't been adversely affected. But in terms of the shaft, this is not really an 'efficient' penis."

I laughed somewhat exasperatedly. "Well, I'm not really used to having more than one option! But I agree – it's high time for Dick 3.0. Just... I don't want it too much longer, yet."

"Really?" the unicorn responded with some surprise. I shared that feeling, even towards myself. I wore my hyper fetish on my sleeve, but...

"I don't want to affect Celestia any worse with this thing until she's more used to it. And, uh." I became a little sheepish. "For Derpy tonight, she's still saved herself in a couple of ways, so... I don't want to be shoving a baseball bat anywhere on our first 'real' night, even if ponies can stretch around it..."

"Ahh. Okay," Moondancer replied in understanding.

"So can you focus on just efficiency and stamina, if you can?"

I heard the shift of her thick-rimmed glasses being pushed up dramatically. "I've got something I can try."

Her horn charged up with magic for only a second before it zapped my cock with a continuous beam. I held as still as I could as I could feel my parts shifting. I tried to pay no attention to the sensation, but there was an unmistakable widening at the base, a thickening, strengthening, hardening all around... It actually wasn't unpleasant at all. The magic inside me seemed to be helping things along properly this time. Some of the magic flowed deeper into my body, following my blood vessels and making painless, microscopic tweaks within my pelvis. A little bit even tingled in my chest.

The active magic sat in my body for a few more seconds, then it all went away. "There we go," I heard Moondancer say. "Scan's gone too; you can look down now."

Good news for my poor neck. I let my chin fall to my chest, and I beheld my newly optimized cock, almost fully hard and pointing straight at Moondancer's mouth. It had gotten a fair bit thicker all around, especially in the middle – I was now qualified to call mine a 'fat' cock.

As my excitement grew, my boner rushed the rest of the way to full hardness with both surprising speed and surprising ease. My erection felt stronger from within, somehow. My hips tightened in anticipation of some serious thrusting action.

I even looked a little bit longer, too, by about an inch. A long, fat, 13-inch cock.

"I thought I said I didn't want it bigger," I pointed out, but I couldn't even finish the sentence before a growing smirk curled up the right corner of my mouth.

Moondancer looked up into my eyes with a distinctly saucy smirk of her own. "No reason not to give Derpy a little extra."

We stared at each other for a few silent seconds, my cockhead bobbing between us in time with my heart.

I started, "Wanna–?"

"We should–"

We both stopped for a second, chuckling awkwardly, and waited for one of us to say what we were both thinking first. It was eventually Moondancer. "We should make sure it's all working properly," she said, blushing but forcing past all her shyness.

"Wanna take it for a test ride?" I said smugly. I tilted my hips and waggled my new cock from side to side.

Moondancer pouted and poked a finger into her cheek. "Ohhhhhh... Oh, alright. If you insist." She got back up onto her feet – bumping her breasts against my jutting erection in the process – and levitated her glasses over to the end table.

My t-shirt was all I had left, so I quickly took it off so I could watch the rest of Moondancer's undressing. I figured it would be a sight to behold. But as I pulled my shirt over my head and tossed it aside, I noticed that Dancer was frozen on the spot. Her arms were up over her head and her magic had grabbed at the hem of her sweater and the waist of her pants, but she had stopped everything to stare at my naked body.

I got more than a little self-conscious. I looked down to see what all the fuss was about. Still the same weirdly undernourished post-magical-liposuction torso. I tilted my gaze back up at the unicorn, silently questioning.

Her pony face scrunched up cutely, weakly attempting indignation. "W-Well, you're not– Guys don't have a monopoly on staring at naked chests," Moondancer stammered.

"Just... never thought mine was worth staring at," I explained contritely.

Moondancer's face softened, and she looked down at me with a more pitying expression.

I covered my face with one hand and groaned. "Sorry. Fuck, I keep killing the mood."

Moondancer smiled and shrugged. "...Mood's not that important right now." And she lifted the sweater over her head with her magic. She wasn't entirely naked beneath – there was a beige, bikini-like utilitarian garment that seemed mainly designed to cover her nipples and reduce their impression on the outside clothing. But a few snaps later and the bra fell away. Just about her entire outfit came off by itself without hardly having to move her body.

I was right; this was a sight to behold. No fearing for my life, no philosophical debates – I could just appreciate her beautiful body. Each pale yellowish breast big enough to cup with two hands. (Her default size. Quite a bit smaller than her enhanced mass on Saturday, but still big and lovely for my tastes.) And her thick thighs staring me in the face...

She stepped out of the pants and panties pooled at her feet and started to climb onto the bed over me. She was a little unfocused without her thick-rimmed glasses, but I decided they enhanced the unguarded, wild-woman appeal she had right now.

Moondancer positioned her body over mine, forcing me to lay fully on my back and stare up at her. Our big sexual body parts grazed each other; my erection poking her belly, her nipples grazing against my chest. The heat between us was starting to get stifling.

Neither of us had the nerve yet to start something or figure out where the flow was headed. Figures, two nerds getting into bed together...

Moondancer let out a nervous laugh. "I can't believe we're just going to DO this."

To quell her nerves and mine, I pushed myself up and kissed her on the lips. She leaned down into it and kissed back, timidly at first, then going wild and forcing my mouth open with her tongue.

Then she pulled back in shock. "The hell! Your saliva, too?!" She licked up the leftover fluid around her lips.

I gave my best helpless shrug. "Sorry."

She started guffawing and rolled over onto the bed to my right. "Fuuu-ha-ha-ha-huuuck! Pascaaaa-aaal! You're a fucking incubus!" She shot a very very light punch at my arm. "That's not fair!"

"Oh good, I'm not the only one who was thinking that," I deadpanned, smirking. I scooted over into cuddling range, laying on my side and pressing myself against her body, my manhood sliding against her thigh. Moondancer bit her lip and just watched me excitedly, rubbing a hand against my back. "But if anything," I continued, steadily lowering my voice into a husky whisper, "I'm a demon that found his way into heaven..." I reached up and caressed the underside of her left breast, slowly bringing it in range of my hungry mouth. "...where angels and goddesses rule."

I latched onto her nipple and licked around her areola, drawing a lusty groan out of her. "Nnnn... So, you think it's all balanced in the end, huh...?"

I didn't answer at first. No milk came out of her breast, but the flavor, the texture, the scent – all more than enough for a tit man like me. Finally, I popped off and rested my cheek against the side of her boob, pleasantly dazed. "Long as I'm no longer poisoning anybody," I said softly. "I inflame your lusts, you all inflame mine... I demand your tolerance, you demand my respect... It's not 'symmetrical,' but it might be making its way towards 'tenable.'"

"Mm," Moondancer grunted. "We get some help with our sex-life balance... and you get all the tits and pussy you want."

Only half-kidding, I replied, "If I do my job perfectly, so does everypony else."

She actually snorted at that. "Okay, smart-aleck. Why don't you put your mouth to better..." She trailed off and shook her head. "No, no, this is supposed to be about testing your penis's health. Let's focus on your ejaculation first."

"69, then?" I suggested without missing a beat.

Moondancer seemed surprised by the offer to eat her out, but quickly smiled. "Mmm. Okay." I rolled onto my back, and Moondancer perched herself over my face, giving me a perfect view of her creamy thighs and big bulging buttocks. I welcomed the smothering that was about to happen.

At the same time that my world became little more important than the fat, wet pussy in front of my mouth, I felt her substantial tits press against my legs and the base of my shaft, and a nervous pony mouth tentatively accepted the girthy head of my cock. Her tongue swirled once, then stopped to savor the initial flavor. I responded with a few deep probing licks and was rewarded with a pleasant, vibrating moan into my manhood.

Like before, Moondancer had a faint vanilla/cream-soda taste to her. Whichever Master had decided to give every pony just a hint of a color-coded flavoring to their sexual fluids, I couldn't really hold it against them. I could almost see the reasoning: Ponies were meant to be sampled in great numbers, like a harem buffet.

But to me, it was even tastier knowing how intelligent this young mare was, and how much she'd sacrificed to help me. I bet that where the Masters and I differed.

I gripped Moondancer's hips and pulled myself deep between her legs. I gave up any hope of light or air for a change to drink as deeply of her as possible. Moondancer pulled off from her exploratory blowjob before she gasped and bucked herself against my head. Our 69 became rather one-sided as Moondancer lost the concentration to keep going and simply rode out the sensations I was giving her.

After spending so much time going deep, I finished off my attacking her clit with just the tip of my tongue, poking and stroking it. That set her off like a depth charge. About a second later, a torrent of pussy fluids splashed over me, forcing me to close my eyes.

Moondancer collapsed against my lower body, flattening my cock against her tits as her labored breath repeatedly compressed her chest against my thighs. "Is..." she gasped, "is your human tongue supposed to be special too...?"

I pulled back, wiped my face with my forearm, and shrugged with a cocky grin. "No, I just think you Equestria girls are supposed to be easy."

"Is that so...?" she replied, regaining some of her sass as she sat up.

"Like I said, 'supposed' to be. My experience has been... otherwise."

Moondancer sat over my head and gently rubbed her dripping, twitching pussy with her hand. "Yeah... You had to use mind control to get this far, and even then I nearly... well..."

My hands, lacking anything else to do, reached around and stroked her thighs. "Any hard feelings?" I felt compelled to ask.

She gingerly lifted her leg and got off of my face. Now kneeling to my right, she shook her head and said, "No. You put your money where your mouth was. That..." She involuntarily rubbed her upper arms. "That's very important to me. That you followed through." With a bit of light laughter, she added, "You didn't corrupt all of Equestria."

"That I wasn't just spouting bullshit to justify being a perv?"

"That your actions actually stayed consistent with that bullshit," she said with a grin.

"Ah, fair enough."

Moondancer caught herself and shot a withering look at my dick. "What are we doing? We still haven't made sure your new cock is healthy."

"Hey, I'm in no hurry," I said, putting my hands behind my head.

The student put on a thoughtful look. "Well, then... We probably shouldn't do intercourse, because we'll want to see it in action... Um..." She shifted down the bed, looking at me nervously. "Would it be alright if, uh, you just masturbated by hand just this once?" She positioned herself between my legs, and the way she knelt over set up her breasts as a big fleshy curtain right in front of my fattened dick. More quietly, she said, "Maybe onto my... my tits...?"

I smiled with a mix of pleasantness and lust. "I'd love to."

Then I reached out and grabbed my new dick for the first time with both hands. Immediately, I could tell – she just hadn't added an inch of length, she had really made it fatter, thicker, stronger, especially around the middle of the shaft. At full erection, I felt like I couldn't even squeeze it that hard. There was just so much muscle mass, with so much blood flowing to make it all turgid, that I couldn't budge it without some effort.

As I gave it a few slow, soft strokes, another change became apparent as my fingers moistened. "I'm... leakier than before," I mumbled, not sure how to feel.

Moondancer was raptly attentive to the motions of my hands and cock, barely even acknowledging the rest of me. "I mean... That's a consequence of not... of not..." She lost track for a good couple of seconds as another drop of precum poured out of my big cock-slit. "Um, of not tightening the base to get that explosive buildup."

"Okay, I'm just– I'm a little worried for the sake of my future underwear and pants."

"Oh no, I guess you'll just have to get 'drained' regularly," Moondancer said with more than a hint of sarcasm. She still didn't take her eyes off my cock.

I actually frowned a little bit. "I'd like to get some semblance of a normal life, eventually."

"Isn't regular masturbation pretty much normal?" she countered.

She had me there. I dropped the subject and focused on giving her a big finish.

I focused on her breasts, aiming my cock at them and appreciating how full and ripe they looked even as they hanged down. She noticed this and repositioned herself. Now Moondancer was more or less sitting with her knees spread far apart, leaning over and cradling her breasts with her forearms, holding them so close that there was less than an inch between my head and her cleavage...

Rather than a volcanic burst, this time my orgasm triggered normally and shortly after I was shooting. Hard. My cum splattered against her pale yellow boobs and splashed against her arms and her chin. And then right on the heels of that shot was another one, then another one.

"Umm...!" was all I could muster in reaction to my cock shooting off like a goddamn rifle. It was almost beautifully efficient, not jerking or bucking but simply maintaining constant pressure, while my urethra did all the hard work of delivering payload after payload all over Moondancer's chest. It went on for nearly a whole minute, and I was so caught off-guard that I was starting to see tiny spots of color in my vision.

Finally, the flow of cum trickled to a steady drip, and my cock returned to a more normal state of hardness. My balls ached pleasantly with relief. Moondancer just stared down at herself, looking for all appearances as though someone had dumped a can of white paint between her breasts.

"Wow," she said.

"Uh-huh...!" I gasped, reached behind me for a pillow so I could prop up my weary neck.

"So, uh..." She looked up at me. "Was that better?"

I scrunched up my face in thought. "Ummm..." It was hard to tell; it seemed like the first orgasm with a newly enchanted cock was always a more intense experience than the orgasms to follow. But they did tend to set the standard in terms of... I don't know, 'behavior.' I tested my cock in my hands, squeezing gently to try and feel out any lingering pain. "I feel fine. Think you fixed the efficiency issue. Maybe pretty far in the other direction."

"Oh." She bashfully looked off to the side. Her horn glowed and began the work of clearing off the cum from her tits, either lifting globs of it into the air or making it disappear entirely with cleaning magic. "I guess I've had a lot of practice. Pony cocks and human cocks, not a great deal of difference."

"I'm not complaining," I clarified. "But if the goal was to make this less intense so I could stand up to Celestia better... I think we've just traded out for a different kind of intense. I dunno, maybe I'll get used to it."

Moondancer scratched her head and made a big ball of my cum disappear from the room. She levitated her glasses back onto her face and gave my body a studious pass with her eyes. "I think, to solve that, you actually need to build up your physical strength and stamina. There's only so much your cock's quality can do for you." She hung her head and groaned. "That was all just an excuse to play with your cock, in the end."

"Hey..." I started, but then I yawned. The tiredness from my early rise and Luna's quickies was catching up with me. "I think you were right to worry about my dick health, at least." Then I realized what I had just done and furrowed my brow. Now that I was thinking about how tired I was, I was noticing that the rest of my body was still pretty fatigued.

Moondancer noticed how grumpy I suddenly was. "What's wrong?"

I rested my arm over my eyes. "They were right. Derpy and Trixie were right. I should probably be getting my rest today."

Moondancer giggled. Her horn's magic washed over me, clearing up some of the stains on my own body. Once we were both clean-ish, she let herself fall onto the bed next to me. "It's not so bad, though, right? You have a palace suite all to yourself, just relaxing... And you'll have lots of days in the future with both of them, looks like."

I sighed and nodded. I just had to swallow my pride a bit, was all. Then I turned my head over towards her. "Y'know, I've been meaning to ask you..."

"Hmm?"

"So you and Trixie came here this morning to visit me and Derpy. When it was clear I might not be back soon and I'd be tired anyway, Derpy and Trixie left to go out on the town and set up some kinda honeymoon night for me and Derpy. I get all that. But why did you decide to stay and wait for me?"

"Oh." Moondancer's face was already a little red from our activity, but the way her face changed shyly made it look like she was blushing even more. "I... kind of wanted to figure out... this, this whole thing."

I sort of saw where she was going with this. "You and me? The 'friends with benefits' thing?"

"Yeah." Moondancer stared straight up at the ceiling. "I think I've figured out what I want."

"And what's that?" I asked with genuine interest.

She let out a sigh. "I kind of want to try dating. Regular ponies, I mean. I don't mind... this, and I don't think any of my future partners will mind either, thanks to your power, but... I think what I want is a permanent partner. And I kinda want to see what regular dating and relationships are like, now that I've kind of jumped past all the sex hurdles– A lot of reasons, basically."

I nodded. That all sounded reasonable to me.

"You're going to be traveling and doing all this sex therapy stuff, and I don't think I want to stay close enough that I'm waiting for you to come back so we can have a deep relationship. But I do want to stay friends, because I like the idea of what you're doing, and the magical science around you is fascinating, and..." She chuckled nervously. "It's probably going to take me a while to navigate the whole dating thing, so I wouldn't mind you coming over once in a while to do more 'penis research.'"

"If that's what we're calling it," I said with a grin.

"Or 'fuck each other's brains out,' if that works better for you," she teased back.

"Either way."

"Yeah." She lost herself in her thoughts for a few moments. "Basically... I don't want to be part of your harem, but I don't mind being one of your 'girls in every town,' if that makes any sense."

"And friends besides?" I asked hopefully.

She looked over at me and smirked. "You're starting to sound like Twilight."

That one stung a little bit. "I just– I guess I don't want to be 'that pervert guy you hang out with once in a while to run experiments with,'" I muttered.

Moondancer put a finger to her chin. "No, you're more like... 'that guy who took me on a magical adventure that broke me out of my sexual shell.' And who doesn't like being taken on a magical journey of self-discovery?"

I raised an eyebrow. "Even when it's harrowing and the guy leading you is kinda dubious?"

"Have you read a youth adventure novel? That's basically all of them!" Moondancer said with a grin. "As long as it turns out fine in the end, it seems to work out."

I managed a short chortle, but found myself the one staring at the ceiling in adrift contemplation. "But what happens after the adventure? When the 'enemy' is defeated and your 'mentor' just turns out to be a perverted guy with superpowers? None of the books cover that."

There was a pause between us as we both considered the question in calm silence. After a short while, Moondancer tilted her head over and said, "Brunch?"

I suddenly realized I hadn't eaten anything yet. I got up. "Fuck yeah. Brunch."
