Summary
Simon's picked up a habit.
Ever since their first time together, an invisible barrier had been broken between Simon and Grace. Grace had always been a tactile person, only spurred on by his years of human solitude, but he felt reaffirmed that it was wanted now that Simon initiated and reciprocated more freely. Arms around each other's waist from behind, chins on their shoulders, hands interlinked and legs tangled on the couch. They played footsies while they ate and Grace would drape himself across Simon whenever he felt like it or his legs got tired because he knew he was strong enough to take it.
They've had sex since that first morning. Blowjobs, handjobs, and actual fucking. It's been amazing.
And every time, Simon asks.
OR Grace gets fucked in the ass.

Movies, books, games, and porn.
Patterns too. How-to's and 3D templates.
With an alien engineer as a best friend and tools left over from the Hail Mary, the biggest obstacle Grace faced when getting what he wanted was overcoming his own anxiety enough to ask.

Waking up slowly in his husbands arms and luxuriating in the calm and quiet morning - no rush to be anywhere, no hurry to get anything done - must surely be paradise all on it's own. He wants to bask in it, let himself be utterly consumed, like an overindulgent hedonist.
OR
Simon begs Ryland to sit on his face.

Summary
One second Ryland sat beside the fire, breathing crying beneath the stars. The next Simon shoved into him hard enough that both of them crashed backward into the sand. Ryland made a startled sound as the blanket twisted beneath them. Sand scattered. The firelight jumped gold across Ryland’s shocked face.
Simon didn’t know what he was doing.
He had never done this before.
Not really. Simon just suddenly could not survive the distance between them anymore.
So he closed it.
And kissed him.
Hard.If you are scrolling late at night with your morals in one hand and your phone in the other and you just want to get to the smut, start at Chapter 11.
Sneak Peek: “The metal thumb of the prosthetic pressed lightly against Ryland’s mouth. Ryland opened for him immediately.”

Summary
“I don’t know if I can sleep,” Grace admitted, tersely. “I can’t get these theories out of my head, even if half of them don’t make any sense. I want to sleep—heck, I want to stop for a bit, take a break maybe—but I just can’t.”
The pad of Simon’s thumb roved over his cheekbone thoughtfully. Then, “Would you like to go down? Do you think that would help?” he asked.
Grace hesitated for a moment, eyes flitting between Simon’s face and the empty space over his left shoulder. “I… yeah. Um. Maybe that would… help. I think that would help.”
Inspired by the filament station discord discussing how Grace can sometimes suffer from problamatic levels of hyperfixation. combine that with his known oral fixation and Simon's need to take care of the man who takes care of him and, well. very sweet cockwarming ensues.
can be read as part of the bite-verse, but also as a standalone.

Summary
“I can’t,” Simon pleaded, voice breaking. “Fuck, Ryland, I can’t, I can’t—”
“Even if I want you to?” Grace asked, and Simon’s breath caught in his chest. “Let go, Simon. Whatever you want to do to me, I’m game.”
“Don’t say that. Fuck, don’t say that. You don’t know what you’re asking for.”
“Don't discredit me. I know what I want.”
Simon jerked away from him with a snarl. “You’re gonna get hurt. I can’t control myself.”
“Then let me help you.”Four months ago, the Eridians found a human welded into a metal box on the bottom of an ocean made of human blood, and somehow that's not the weirdest thing about the man. Even after they let him out of quarantine, he doesn't talk much, and Grace keeps a cordial but distant relationship with him--until he gets sick with some mystery illness and Grace gets tasked with helping him recover, because surely he knows what to do. (Spoiler alert: he doesn't. But he figures it out.)

Summary
“I know it’s a little late for this, but I was thinking we should be exclusive,” Deadpool growls, halfway through the window with his gun out and pointed at the mound of comforter between Peter’s legs.
“What the fuck,” Peter gasps. His thighs clench around Wade – it is Wade, isn’t in? – more because his entire body seems to be clamming up in shock than because he’s that desperate for an ill-timed orgasm. It really isn’t helping that Wade’s still going at it.
“What the fuck is right,” Deadpool says. He cocks his gun. “This motherfucker has ‘til the count of three before I blow his brains out.”
Or: Deadpool gets cut in half, resulting in two Deadpools. A threesome ensues.
