Summary
"But Grace have sex in crew quarters sometimes."
"That's not— you shouldn't—" Grace shakes his head. He knows Rocky doesn't mean to make him uncomfortable. Heck, Grace's biggest problem at the moment is that the knowledge of Rocky watching him doesn't make him uncomfortable. Not in the way it probably should. "It's not really sex. Since I'm by myself when I…" he trails off and hopes that's the end of it.
"Rocky is here when Grace have not-sex."
"No, I mean—" Grace sighs and tries not to pull out his hair. "It's only me. Touching myself. You don't touch me."
Rocky sinks back on his hind legs and goes quiet in a way that Grace recognizes as careful thought. Stony fingers click together and drum against the aluminum composite flooring. When Rocky speaks next Grace nearly falls off his stool.
"Grace let Rocky touch, question?"

Hiro's sweet tooth has gotten out of control and Aunt Cass has begged Tadashi to find a way to get him off his favorite lollipops. Tadashi, rising to the occasion, invents a flavor spray that can make anything taste sweet—the only catch is the user needs to be blindfolded. While Hiro is product testing, blind and unaware, Tadashi's temptations get the better of him.

No Less Than Nothing: A Ryland Grace Classroom Series by cloudberryyy
Fandom Project Hail Mary (2026), Project Hail Mary - Andy Weir

Summary
Best read in order <3
Slice-of-life classroom days with Ryland Grace.
A rotating cast of kids (Emma, Mia, Malik, Luis, Leila) + one meteorite labeled UNKNOWN as the moral center. Science shenanigans, found family vibes.( I probably should add a “don’t try this at home” tagline for all the science )

Summary
One "Broken Toaster." One "Viper" Therapist. And a clinical disaster that’s about to go off the charts.
To the elite of West Hollywood, Kim Taehyung is a miracle worker—the "Sultan of Sensation" who can fix any relationship with a silk turtleneck and a baritone hum. He is professional, high-maintenance, and currently trapped in a "Celestial Purity" vow with his yoga-guru boyfriend.
To the rest of the world, Jeon Jungkook is a superstar graphic novelist. He’s handsome, shy, heavily tattooed, and built like a god. But he has a secret that even his bio-hacking girlfriend can’t fix: his libido is a total flatline.
When Jungkook begs for a "hands-on" medical intervention, Taehyung’s 98% success rate is put to the ultimate test. Between "Scientific Marinations," accidental-nudity collisions, and a boyfriend who thinks ink is a spiritual sin, the two are about to find out that the best way to fix a heart isn't through a spreadsheet—it's through a total Manual Override.

Summary
“Then…” Enid steels herself. “Then can I touch myself, or not?”
Wednesday exhales, uncrossing her arms. “You may.”
This fucking girl.
“Fine,” Enid says in a small voice, scooting back on the bed.
She feels cowed and decidedly not turned on, shoved as far away from her as possible against the unforgiving headboard. This was not how she saw her Thursday afternoon going when she escaped to find some privacy.

Ever since she’d been small, Hermione’s reward for good marks had been a rampage through a bookshop, so the day she tore open her O.W.L.s results and triumphantly brandished the eleven Outstandings, her beaming mother said, “We’ll go to Foyles tomorrow,” without any discussion required.

Summary
The inherent eroticism of being perceived with curiosity and without judgment. Or, what if you were on your way to Tau Ceti e to save the world, and your alien best friend watched you get off for science, and then you learned some interesting xenoanthropological facts about Eridian mating customs? Well, it happened to my buddy Ryland Grace.
"You can see?" I whisper.
"I hear." Rocky matches my quiet tone. "I hear everything."
And that's interesting, because those words fuse white-hot with my pulse, and earth themselves with a thump between my legs, and all of a sudden I'm not soft anymore.
Okay. Yeah. We're way past being shy.

Summary
At our next Maximizing Rocky Happiness meeting, I pitch my idea to Adrian over a walk down the beach.
They don’t say anything for several seconds after I finish my explanation. Maybe it was a bad idea to share. Finally, Adrian asks, their tone dry, “You want to put Eridian eggs inside squishy human body, question?”

Summary
Grace’s foot caught on the bottom of your cardigan. He tried to catch himself, but it was to no avail. After a few seconds, he crashed, hard, into your lap.
You, thankfully, cushioned his fall. It could’ve been a lot worse. You were only a couple days away from retrieving the predator sample, and Grace couldn’t very well collect anything with a broken bone. He heaved a sigh in relief.
“Uh, Ryland?”
The relief he’d felt moments ago was replaced with dread. Grace shot up from where he’d landed and saw you covered in Rocky’s powdered 'seasoning'. He glanced down at himself after.
The gloves had kept his hands safe- yay! But, every other inch of his body was coated with the same power. The now empty, deep jar sat just a few inches away from the two of you.
Oh god. Nearly everything on Erid was lethal to humans. Grace very well might have just killed the two of you, and Erid and Earth could kiss the solution to their problems goodbye.
or: grace and reader have a cultural exchange with rocky in the form of video interviews. in the middle of one, they get an accidental, large dose of what ends up being sex pollen for them and have to bang it out. a lot.

How do you explain sexual arousal to a guy whose species doesn't experience it? Whatever the case, Ryland Grace is definitely not the right person for the job.
Unfortunately, a hands-on demonstration might be in order.

Summary
“I guess, um,” I say, licking my lips as I stall. When did my mouth get so dry? “I don’t know why, don’t ask me why, but… you’re… obviously a lot stronger than me, and I guess that… activated some part of my brain that’s… into that, I guess.” I wring my hands, fussing with the arms of my jumpsuit tied around my waist- anything to avoid looking up at Rocky. “It’s just… been a long time since I’ve, uh. Mated with anyone, on Earth, and I think I’ve just been a bit- frustrated, so my body’s just reacting to whatever it can. Don't- don’t get me wrong, I know it probably doesn’t make a lot of sense, I mean- you could literally crush me if you wanted to, but- for some reason, I… I guess it was just… exciting. To me.” I finish lamely.
Rocky stares at me, as much as a being with no eyes and 360 degrees of echolocation ability can stare. I am acutely aware that he can hear every beat of my heart, every hitched breath. He can probably sense the pinpricks of sweat that bead on my forehead. I swallow, my heart hammering in my chest at the silence.
Rocky finally tilts his carapace ever so slightly. “You are aroused by strength in mate, question?”

Atmosphere, Explained by cloudberryyy
Fandoms: Project Hail Mary - Andy Weir, Project Hail Mary (2026), Bill Nye the Science Guy
28 Mar 2026
Tags
Summary
When porcupinesarentreal said, "In a universe where Grace goes back to earth, he would absolutely kill it on Sesame Street,” but sage-rats commented: „Get this man a guest spot on Bill Nye the Science Guy.”
or
Back on Earth, Ryland Grace is invited onto Bill Nye the Science Guy to help explain air pressure, vacuum, and why the atmosphere matters.
It should be easy. It’s just science. Just a studio. Just a room full of kids, cameras, demo props, and one relentlessly enthusiastic host in a bow tie.
But between vacuum chambers, imploding cans, and one disarmingly simple audience question, Ryland finds himself talking about more than physics. About pressure. About fear. About what Earth gives you every second without asking for thanks.

Summary
At thirty-one, Satoru has everything: power, prestige, and a thriving biotech empire built by his own hands.
What he doesn’t have is… a child.
Satoru doesn’t want just any child. He wants a perfect daughter, crafted by science, designed down to the last strand of DNA. To achieve this, he selects a surrogate: Yuuji Itadori, a young omega whose genetics are ideal.
To Gojo, Yuuji is nothing more than a file, a profile. Love has never interested him, and a mate even less.
But contracts have consequences.
Because behind the perfect genetic match is a person painfully human who catches him off guard and make him question his entire worldview.
Satoru never planned for his surrogate to start trying to affect him in ways he can’t explain.… and win his heart.

Through the spite of the spirits or plain rotten chance, a door that would have been better left untouched has opened. On the other hand, with Fire and Earth as one's allies, sometimes escaping is the easy part.
