Centipede alien aesthetic and ideas (NSFW, oviposition, and lots of goop...) (Patreon)

Came up with this idea in a half-doze this evening, and wanted to share. Warnings for eggs, oviposition, incubation and goop... Gender neutral reader and alien. 

Human is on a mission, their fighter gets damaged and they end up on a planet which is quite hostile. They see the alien scuttling around in the valley below and don't realise they're in heat and desperately full of eggs. Long story short, human slips on a cliff edge and tumbles down the mountain slope, miraculously not breaking anything, and ends up practically at the alien's feet. Instead of attacking, the alien takes the human to their cave and tries to care for them, but is so horny it's difficult for them to think straight. 

Human wakes up to see the alien trying to take the edge off their arousal, black, viscous goop dripping down their abdomen and onto the floor. It doesn't speak any language that the human recognises, but makes chittering and clicking sounds. 

They manage to communicate rather crudely eventually, but the alien is so close to the peak of their heat they can't stand being so close and not filling the human with their eggs. As the human takes their suit off, discovering the tear in the fabric which means they've been breathing the atmosphere fine anyway, they alien starts gushing black goop from their slit and making desperate, rumbling whines. Turns out the human's body temperature is exactly perfect for the eggs, and their heat sensitive antennae just picked that up... 

Human eventually works out what's going on when the alien traces lots of eggs in the dust with its claw and then indicates their ovipositor which is already starting to unsheath itself. They're desperate. 

They start nuzzling against the human, who finds it oddly arousing, and eventually the human consents to being a host for the eggs, once they've ascertained that they're not going to hatch inside them, or that they're not going to devour, take over, kill, eat, etc. them...! Safety first...  

Once the alien has filled the human (most of the eggs actually slide out and the alien is heartbroken at the sight of them, but some stayed inside), the alien becomes massively protective and very tender. They feed the human some tubers and other roots that are surprisingly tasty, and make sure they're comfortable and hydrated. 

The eggs are ready for hatching about a month later and the human experiences searing cramps, but it's not so bad with the help of some special venom/secretion/saliva from the alien that numbs the pain and actually ends up acting as a massive aphrodisiac. The eggs are laid, and the alien holds the exhausted human tenderly, helping to ease them through the process. There are only three eggs, but each time one slips out, the human comes. 

Alien is hugely turned on by the sight of the human lying in their arms, and when the human is finished, they seek permission and when it's granted, they take them, first gently, then roughly. 

The eggs are then allowed to hatch, and just as the last one hatches, the human's tracking beacon comes back to life. 

It's been activated by a passing ship, and they have to leave. 

The alien holds them close, chittering and whimpering, and the little hatchlings cling to the human's leg, but eventually the alien scoops their little clones up into their arms and takes the human up to the top of the cliff to wait for the ship to pick them up. 

The ship lands, and the human says goodbye. Maybe they'll return some day with some earth soil and grow a variety of things, and make a home there with their alien and the little clones...
