Happiness Comes from the Anal (1)
"Ahhh..."
"Sorry. That was a bit much after all, wasn't it?"
"I-I'm fine. It's just a little sore."
Yesterday's experience must have been intense enough that Nia could still feel a dull ache in her empty rear. I figured the culprit was how roughly I'd taken her on her very first time.
"It's not that it hurts, exactly. The problem is it keeps tingling, and that just makes me feel dirty."
"...Ahem."
At least Nia's willingness to play along with me so far had confirmed that the magic I'd designed worked exactly as intended. Once activated, a cleansing module scrubbed the rectum clean. After that, a secondary module suppressed intestinal activity so the freshly cleaned space wouldn't get dirty again for a while.
That much was exactly what I'd planned from the start. But using the spell at all meant you were about to put serious strain on the sphincter, so I'd added a light restorative enchantment to help compensate.
Honestly, healing from a slightly sore state makes the area more sensitive faster. Better for development that way.
It was a feature born of careful thought from every angle, and it had been a huge help while I was training Nia's ass. Last of all, I'd included a function that made it obvious the spell was active: the words Ready for Use appeared on the upper curve of the buttocks like graffiti.
I'd felt the full effect of that one while taking Nia doggy-style. There was something incredibly arousing about magically unlocking a hole that wasn't meant to be used and then putting it to work. The added visual kick was fantastic. Considering how much more complicated it made the magic circle, I'd completely thrown efficiency out the window—but then, anyone who cared about efficiency would have just used a pussy for sex in the first place.
Hell, if efficiency were the point, contraceptive magic would be the smarter route.
The truth was, the reason I'd dragged Nia into the swamp of anal play at all was that I couldn't cast contraceptive magic on her pussy. With the Order of Mijia as the state religion, this world refused to tolerate anything that interfered with the sacred act of childbirth—magic included. Public opinion made circulating that kind of spell nearly impossible.
Anal sex, by contrast, didn't carry the same stigma. The sense was that people did it not for contraception but for the unique pleasure it offered, so it escaped most of the scrutiny. That was a genuine relief. If the Order of Mijia's doctrine had been strict enough to taboo ejaculating anywhere but a vagina, then anal sex—and oral, and titjobs—would all have been crushed under the Church's boot. Honestly, for a world where even basic contraception was this hard, they were practically saints for leaving us this much room.
"Let's skip the magic today and rest."
"Do we have to?"
"Yeah. We overdid it a little."
I'd been leaving the spell running far too often lately in the name of training. Keeping bowel activity suppressed for that long could cause problems. No matter how carefully the magic managed things, forcibly overriding a natural bodily function couldn't be good for you. From what I'd heard, the technique was originally meant only for emergency stopgaps.
"I'll need to revise this part."
Given the magic circle design I'd already settled on, the drawing itself would stay the same—but I could add an option to fire the spell without the intestinal suppression if the user wanted. At the training stage, as opposed to actual anal sex, that function was basically unnecessary anyway.
"Are you getting up, Cali?"
"I've got manga work to do."
"Ah..."
Even after sleeping for ages, Nia's body was so exhausted she couldn't drag herself out of bed. Instead she sank into another stretch of sleep so deep it almost felt excessive. Still, the occasional day of sleeping in like that was probably for the best. Lately I'd been cutting into her rest for anal training, so she needed days to recover from the fatigue.
"Hah. Where was I again..."
The new series I'd started working on was titled Happiness Comes from the Anal—a name that made it obvious at a glance this was a sequel to Happiness Comes from the Breasts. The actual tone of the work, though, was going to be quite different.
Like the previous series, it would go all-in on the erotic and use an omnibus format. The big difference was that this time the protagonist would always be the same person. In the last work, the lead had changed with every episode.
That single-protagonist setup was closely tied to the anal-sex magic I'd been refining all this time. No matter how carefully I'd polished the design, the spell was still the work of a magical novice. I'd just assembled the readily available modules into something that looked plausible. But a lot of people believed Siwoo was a grand mage. If a spell he casually tossed into a commercial work turned out to be that rough around the edges, it would raise eyebrows.
So I'd thought it over and decided to include the creation of the spell as part of the story itself.
The protagonist is a novice mage who loves anal. The story opens with him developing this magic himself.
That way, readers would assume the spell was deliberately simplified to fit the tone of the work, and it would also help them immerse themselves more deeply. Honestly, I couldn't think of a better solution.
With that structure locked in, and given how the previous series had split its themes across different characters in omnibus fashion, this one would keep the same protagonist while rotating through heroines. Four heroines, plus the opening episode about developing the magic—that would give me five episodes total, just like last time.
"First episode starts simple: pure anal sex."
It would focus on the process of developing a rear hole into a proper second pussy, then the actual anal sex that followed. I'd gathered such excellent data this time around that I could lean on it heavily and still produce something solid. Since the basic flavor was the most important part of the whole series, this was also the section that needed the most attention to quality. The character design would stay relatively ordinary to match.
Next: a heroine who loves taking it incredibly deep.
The main content would revolve around training with an anal dildo of ordinary thickness but absurd length. I planned to introduce a new concept here—a long, soft, floppy dildo—though I'd only present the idea in the work itself and leave actual product development to someone else. The centerpiece image would be that impossibly long toy sliding out of her ass in a glistening rush, the sensation pushing her over the edge until her legs gave out and she collapsed. To sell the wonder of hiding something that long inside such a body, I set her as a slim, slender type.
And if we've done long, next we do thick.
I'd also include a chapter centered on thick anal insertion, with the fun of watching the training dildos grow progressively wider. It was a harder edge of the fetish, but leaving it out of an anal-focused work would have felt incomplete. I'd just have to write plenty of careful notes about the training process. Once development was complete, the heroine would showcase the appeal of an anus stretched obscenely wide—so while she didn't need to be slim, I planned to keep her height and hips on the small side. That way the contrast between her tiny frame and that massively gaping hole would hit harder visually.
"And finally: the tail."
This world had races you could call beastkin—people with animal ears and tails. I planned to draw a chapter about fitting something like those tails as an Anal Plug Tail. This heroine would have enormous breasts and a full, voluptuous body that didn't look particularly agile. Honestly, the idea of someone twitching their ass to wag a tail was just hot. Picture a soft, heavy body that wasn't quick on its feet—except for the tail buried in her ass, thrashing around with pure excitement. That contrast alone would be incredibly arousing, so I locked in the design.
Four heroines felt like the right number to properly express everything appealing about anal. Of course I'd packed each one with smaller distinctive traits as well, carefully making sure no little charm went to waste. And I hadn't forgotten the meticulous detail in the training sections, so nobody would end up with health problems from trying to copy it.
"So even though this is a sequel, that means no pre-orders this time?"
"That's right. Instead, there's a bonus item we would normally have given out with pre-orders. This time it'll be included with every copy as a permanent freebie."
After that conversation, I threw myself into the new work and finished the manuscript faster than expected. The moment the cover design was done, I booked a date and headed in to submit it. Drawing page after page of pure, heartfelt anal art for the first time in a while had been deeply satisfying.
After some thought, I'd decided the cover should feature the most attention-grabbing body of the lot. Front and center was the busty, voluptuous heroine wildly wagging her Anal Plug Tail. Looking at it now, she was an outrageously lewd character. Which, to be fair, she actually was.
"So this new work includes a spell the protagonist uses, correct?"
"Yes. We'll need to include a booklet explaining it with the published volume."
"Is the spell that important?"
It was. You needed it if you wanted to experience the work with your own body. Judging by how popular breast training had become last time, anal training would probably catch on too—maybe not quite as hard, but enough. And since the spell was essential to that trend, there was no way around including it.
