the mention of the nautilus got me thinking of somethin entirely different.
gordn is a deep sea scientist, and is sent in a one man mission in a submarine to previously unexplored depths. there's been wierd sounds and seismic activity recorded here, but BM doesn't tell him that. he's just there to test the capabilities of their new manned submarine and take readings.
except that things start to go wrong. he loses contact with the surface. and he keeps hearing strange sounds, seeing strange sights in the cameras. then the alarm blares - the protective casing on the sub is failing. as well as the navigation. and the motors. this thing is going to fall apart and he's going to die at the bottom of the ocean.
and just as water starts leaking in, the casing on the sub breaches in, and gordn flinches - panic overwhelming his mind just as he thinks he's about to die.
because benr, a massive underwater creature, has been circling this little interloper for the better part of 4 hours. there's something alive inside, but he can't tell what. and then it starts to shriek - stuttering and falling lopsided towards the ocean floor, its alien lights flickering out and leaving them in darkness (which benr prefers, and it allows him to swim closer)
there's something in there, and he wants it. he's got to crack this thing open like a wonder ball. but he's smart enough to understand that whatever's inside may be destroyed by the force of the water rushing in. so he does the only sensible thing:
he takes the whole one man sub into his mouth, and, keeping his lips shut, gently bites it open. what falls onto his tongue surprises him. something warm. something warm and alive and gasping for air.
being a deep sea creature, ben probably doesn't have access to air. so let's say that sweet voice nonsense can generate air, replacing the water in his guts and mouth.
gordon coughs up water, half unconscious. ben gently pins him to his pallette and spits out the rest of the sub - he has his prize. he swims deeper, back to the trench he calls home, to curl up and prod at the warm little creature in his mouth.
ben knows what a human is. but humans aren't supposed to be down here. he closes his eyes and lathes his tongue gently over his little captive, building an image of him in his mind through touch. so, so small. but strong for a human. thick around the middle. long hair. tastes like sweat and neuroticism. something about it - him - interests ben, even though gords not awake yet.
gord is gently coming to in the warm confines of bens mouth. the cold, cramped interior of sub and the frigid water spilling in has been replaced with bone-deep, humid warmth. and something warm and plush keeps pressing against him, moving him around. the jostling rouses him and he opens his eyes to ... darkness. is he dead? it takes him a moment, but only a moment, to put several things together - his sub breaking. the humid heat. the strange pulse against his skin and the movement of his surroundings -
he's inside something living. his sub broke, he didn't die, and something fucking ate him.
his first instinct, of course, is to panic. he thrashes in bens mouth, not really thinking about the fact that the deep sea is outside, just - acting on instinct. he doesn't want to die like this, swallowed alive by some unthinking monster.
Ben is taken aback by the sudden movement. he can't talk to gord and tell him to calm down, so he pins the tiny creature with his tongue, trying to still his movement. he's also just... curious. about the way the movement feels in his mouth, different from anything else he's ever eaten.
the attention only makes gord panic more, though, so ben decides the only thing he can do is swallow him down so that he can use his mouth to speak. Then maybe he can get this little guy to chill out.
this is getting long and im tired, but ive got more ideas for what comes next :)
I've seen similar kinda stories/aus like this where they just have benb as a giant mer, but.
I'm thinkin more along the lines of Deep One benb
grats gord, you just got rescued by gamer bro cthulu!
