au where dainsleif is an alien with tentacles and diluc is an astronaut (more trans diluc smut 😩)
diluc curses when the alien easily disarms the weapon from him and seizes all four of his limbs with dark, slimy tentacles.
despite his valiant efforts to break its hold, the alien latches on. diluc stares fiercely at the humanoid alien as it…or rather he lifts diluc into the air and draws him uncomfortably close.
he’s about to spit profanities when the alien forcefully spreads his legs open and trails a tentacle along his…diluc involuntarily jerks at the unexpected pleasure, gasping at the sudden touch.
“what are you…” diluc begins, before the alien tears his suit open to expose his cunt. his eyes widen in realization, and he struggles harder, to no avail.
“don’t—” he protests at the large tendril slotting between his lower lips in a slick glide, leaving a trail of slime coating his entire pussy.
diluc chokes on his words when he feels the thick tentacle slide deep inside him, the slime easing the way. it doesn’t stop, driving deeper and deeper until it rams directly into his cervix.
he comes almost instantly, body trembling as he squirts helplessly onto its length. his fluids only excite the alien more; another tentacle latches onto his clit, suckling eagerly.
he sobs almost hysterically when the alien’s tentacle doesn’t relent and even picks up its pace, causing slick and slime to gush out with every thrust. it’s wet and messy, splashing onto diluc’s thighs and the alien’s humanoid stomach.
“no, i can’t—” diluc whimpers when another tentacle feels along his labia. apparently, he can. diluc’s vision almost whites out when the tentacle is forced in alongside the other one, stretching his walls impossibly wider.
“dainsleif.” the alien’s voice cuts through the haze of pleasure and pain. diluc blinks his tears away to look at him, chest heaving with every breath. was that his name?
diluc doesn’t know, but when he moans out the word at a rough thrust, the alien seems pleased
