Reading Small Gods and I'm scandalized to see that they use em- and en-dashes interchangeably. In one case, an interjection even had an em at the start and en at the end! Feels great to reach Pratchett again, though. Like slipping into a hot bath.

I'm obviously biased towards the very first picture of my bird! (Curtsey of @korilsnake.bsky.social ) Aside from that, I really adore Where No Hyper Has Gone Before and A Swell Sacrifice (which I really wanna turn into stories of my own at some point). I drew tons of inspiration from earlier art.

Also, I don't know if Bermasin will mind me sharing their art from Furaffinity (I don't think they're on bsky?), but it is a massive mood and part of what set my inspiration on fire. (Even if I might go for macro/giantess or insanely huge dickgirls, too...) www.furaffinity.net/view/63674307/

This image graced me with inspiration to ask the question: What if a sexy superheroine interrogates a villain with her growing tits? Wrote 2 pages tonight, might continue it later! www.patreon.com/posts/sexy-1...
Shade, in spite of his circumstances–shackled to the table in a steel cage of a room, nothing but gunmetal grey and mirrored glass around him–was smiling. “You can’t break me,” he boasted. “You’re a hero. You’re not allowed to get your hands dirty.”

Solar was a hero, that much was true. She was also a bombshell, in several meanings of the word; strong enough to fold the man opposite her like a piece of origami, beautiful enough for the glitzy magazines, and busty enough that any such photos would get the publications in trouble with the decency police.

She sat opposite the debonair super-thief, in the uncomfortable little chairs of the interrogation chamber, watching his attempts to taunt her not so much with a glare as with a look of quiet appraisal. Just another day at the job.

“Alright,” she began, “Let’s get the preliminaries out of the way. Will you tell me where you stashed the royal jewels?”

“Come now. You’ll have to do better than that. One might think you’re aiming to offend me.” Shade spread his hands (as far as his bonds allowed) and laughed. “What’s it matter to a heavy hitter like you, anyway? The king has plenty of cash. He’ll hardly miss a few trinkets.”

“Right. I’ll put that down as no then.” 

“Unless you make it worth my while. Which I’m certain you can’t.”

“Let’s find out.” Solar looked him straight in the eye. “Drop your pants.”

The first crack in Shade’s facade appeared. “W-what?”“Your cock. Get it out.” The blonde heroine was as matter of factly as could be, smirking only slightly as she peeled off the top of her pure white and gold uniform to unleash her monstrous, perfectly shaped tits upon the would-be mastermind opposite. “You’ve been staring at them ever since I stepped into the room. Let me give you a closer look.”

Shade wasn’t in a position to refuse, his attention stuck as securely to Solar’s bare breasts as his shackles were to the table. Until she tore his chains apart with a flick of her wrists, and left her as the sole source of authority in the room.

The thief opened and closed his hands momentarily, saying, “I’m free…?” as he–too slowly–realized he was anything but.

“Your cock,” Solar repeated. “Give it to me.”

The heroine would brook no argument. She loomed over him, a half-naked monument to femininity and erotic power, so close that he could smell her perfume. Even during their chase, when she finally caught him and tossed his hoverbike into the sea, he hadn’t been this close to her. Now he was–and his world of plans crumbled to dust as the thoughts of her sexy body and what she might do to him thrust into his brain.

She didn’t leave him to fantasize. Solar stripped him forcefully, her smile resurfacing as she found his cock, hard and eager for her, and she wasted no time getting down to her knees to envelop it in a canyon of cleavage. “Not bad,” she said. “I can have some fun with this.” 

“Likewise,” Shade gasped, fighting for control. “I’ll… accept this offering.” Control, in this instance, being the simple act of regaining the use of his body, to reach down and squeeze the world-famous pair of tits wrapped so snugly around his dick.

“Oh, this isn’t for you. It’s for me.” She had only just begun her slow, sensuous titfuck, and he was already trembling in her grasp, begging to release between her fat, jiggling tits. She watched him, grinning slyly, as she brought him to the edge, dancing precariously at his limit unt…

It's slow going, but I started chapter 3. Can I eventually figure out how to handle a longer narrative? We'll find out, come hell or high water.
The restaurant was a fancy fusion affair in the upper district. Valdemar had never seen a fleet of waiters so well-dressed and so numerous, and the prices of the evening menu reflected that. He and Dez had made it to their reservation on time, against the odds, and the one Lyra that had a full set of clothes had reluctantly agreed to tag along.
“So,” Dez said, sipping her cocktail. “I’ve got a great plan for us…”
“But you’re not mad? Not even a little bit?” Valdemar still couldn’t believe it. “Caught me fucking around with an angel and that’s it? Not even a little fireball my way?”
“Val, you do what you gotta do. I’ve seduced a lawman or two in my time to get out of trouble, too. I’d be a terrible hypocrite to hold that against you.” Dez grinned proudly, as if to point out that he’d have to do better to beat her on that particular scoreboard. “Even if the fruits of my efforts weren’t quite as plentiful as yours.”
“There is that. Very fruitful,” Valdemar agreed, glancing sideways at Lyra, who as yet did her best to pretend that she was too dignified to take part in this conversation. “But I thought you guys were sworn enemies. Bound by law to fight. If you’re going to duke it out, we’d better find a cheaper venue, is all I’m saying.”
“Gods, no.” Dez laughed. “In principle, sure, but who cares about that? Blind fervor is above my pay grade. And below it, come to think of it. You’ll have to ask your feathered girlfriend over there which bracket she’s in,” Dez said, eyes glittering with mischief.
“None of your business,” Lyra replied, returning the serve with a sharp rebuke.

Feeling a little Hitchhiker's guide to the galaxy.
Many a world has fallen pray to the self-reinforcing cycle of growth-orgasm-growth. It’s one of the better arguments for the existence of multiple dimensions or cyclical universes; if a single hyper or macro getting their rocks off was enough to end existence for good, we wouldn’t be here to read about it. So really, given the penchant for any sizable population of growers (which could be as little as one, by definition) to smother the planet and/or universe in curves, muscles, or cocks, there was no need to panic. We’ve all been here before, and we will be, again.

This is a beautiful sentence.
If you were outside, any conversation just had to stop and wait and wait, until they came in low and large enough to blot out the afternoon for a second, like the sun just winked at you. You could look up and see empire then, even if you didn't know what you were looking at.
