author's note:
yeah hi I am ironic and hella fucking offensive. Fight me about it.
Super NSFW and generally weird. Reader discretion advised.
Zim really doesn't give a fuck about going slow. Not after everything.
(It's not like if he needs more stretching. He's had a buttplug deep in his ass for two and a half hours- he doen't understand human physics very much, or could he care any less about them, and Dib's presentation was fucking boring. That's all he has to say about it- and he really hasn't the patience for it, anyways).
Dib smiles and rubs circles on Zim's thighs (which are wrapped around the human's waist- for leverage, yeah, because wall sex is surprisingly uncomfortable, but neither of them could honestly give less of a shit now), kissing the hollow of Zim's neck and his chin and his open mouth. "You've been good, Zim," Dib says.
"Fuck yes I've been. No time for this foreplay shit you seem to love so much though," Zim replies breathlessly, arching his back and pressing against Dib. "I really want to be fucked. Preferably by you."
Dib chuckles, and kisses Zim's cheek, fingering at the rim of his entrance with slick digits. "Impatient," he whispers in Zim's ear, low and husky and sexual.
"Yeah," Zim grunts, pushing back a little with his lower back and looking up at Dib's with hazed eyes. "Now shut up,"
Dib laughs again, and lines his dick against Zim's entance, pressing in slowly and painfully (not in the way it stretches, but in the way it seems to be taking forever for Dib to be completely buried inside Zim- he's probably doing it on purpose, the sick fuck).
But then Dib is all in and Zim's breath hitches and he hits his head against the concrete behind him- he bites his lip and Dib leans against him, moving his hips in long and blissful circles and then pulling out slightly, then slamming back in again, fucking Zim on shaky legs and with snapping thrusts, sometimes even bending his knees and adjusting his arms and leaning over a little so his forehead touches the wall and his dick leaves Zim all but the tip- then he leans back and slams into Zim, in just the way and angle that makes the brunet mewl and scratch at Dib's clothed back.
It's messy- Zim's shirt is stained and ruined for sure, and he really has no option but to put the plug back in because he has Dib's gross come already dripping out of him in slow and warm lines- but it's also really worth it.
Dib's lips on his, all tender butterfly kisses and sweet caresses are always worth it.
