It Takes Courage by lucanidsoap
Fandoms: Project Hail Mary - Andy Weir, Project Hail Mary (2026)

Summary
Ryland Grace is a coward. Always has been. He doesn't take risks, and his failed scientific career, failed friendships, and failed romantic life don't prove otherwise. But he saved Rocky, whether that be out of selflessness or the fear of being alone again. He took a risk.
Grace is glum in the midst of waiting for Taumoeba-06 to evolve (any day now), burdened by loneliness and touch-starvation. Attentive Rocky notices this in Grace's demeanor and checks in on him. Grace confesses how much he misses physical contact and surprisingly discovers the feeling is mutual.
Rocky engineers a solution. Something that will drastically change the course of their relationship.
Or
Rocky engineers a method for him and Grace to hug. This escalates to Rocky pleasuring Grace, a misunderstood confession of love (language barrier), regular physical contact (among other things), and reaching a mutual understanding of what their relationship means.

Let Me See You Stripped Down to The Bone by lucanidsoap

Summary
Within Eridian clusters, it is very normal to mate with fellow members. Some mate bonds are primary, like my relationship with Rocky and Adrian. But others are secondary, taking on a more platonic shape. Eridians don't experience shame when it comes to sexual relationships between cluster mates. To them, sex fulfills a biological need, as eating does for me. It's not taboo to mate with multiple partners; in fact, it's encouraged for producing the most viable offspring. The more variation among worker cell DNA in the fusion process, the better.
That's where we are now. Multiple mates. Multiple clutches. All inside me.

Chain, Keep Us Together by lucanidsoap

Summary
To amuse myself—admittedly, grown tired of this monotonous routine—I've decided to punish my human for his chain-making incompetence. I wordlessly stood up, restrained Grace with the length of chain I had just produced, and forced him down onto the ground. He protested, but the knowing dilation of blood vessels within his sex organ betrayed his words as it became erect.
I allowed my ventral seam to split open. Mercury dribbled all over his lower body, his clothed erection. I held his hips down, forced open his garments, and sank down onto him without acknowledging a word.
I resumed the chain-making process.

A part of him regrets agreeing to Rocky's conditions. He propositioned him in such a mischievous tone. "Grace, I have an idea. Something we could incorporate into our next sexual encounter." Nothing could've prepared him for what came next. "What if I fucked you while you explained science to me."
