Def need more of your thoughts on Clark bumping against Lex's cervix
it’s painful. not much, nothing lex luthor can’t handle, but he knows he is gonna feel sore as fuck tomorrow. he likes it, though. likes the way superman not only metaphorically rearranges his guts, but quite literally. likes that if superman comes like this, his seed would be inside the uterus. likes what it implies. it makes him wet. opens up quite a lot of new possibilities, too.
lex tries to keep the pain out of his expression and his sounds, but nobody can be perfect when a superhuman fucks them three ways to sunday. so, ultimately, lex lets out a few pitiful sobs — he would be terrified about those sounds later — and tries to jerk away from the big cock that is splitting him wide open.
“baby? what’s wrong?” superman asks, immediately stopping his thrusts, still buried to the hilt, the tip of his dick resting against the cervix’s opening. lex shuts his mouth with a click, facing away from clark’s worried gaze. this should be above him. his partners do not worry about him during sex, they do what were told to do and not a thing more or less. but superman is no ordinary partner. he is kind and sympathetic and so utterly alien. and he wouldn’t comply if he didn’t see a good enough reason.
“you can continue.” lex replies, his face still looking at the wall, his fingers gripping clark’s shoulders a bit too tight.
“what?” of course superman is going to be like this. tear lex’s chest open and show his vulnerabilities to the silent room. tell every inanimate object in there that lex luthor is, fundamentally, human.
there are tears gathering in the corners of lex’s eyes. it’s such a stupid thing to get emotional over, but he cannot just will the emotions away. he hates knowing that superman sees his tears the moment the first particle is formed. it feels so, so human. which lex luthor should not be. but he is.
“talk to me, lex. i won’t continue until you tell me what’s wrong.” lex dares to throw a quick gaze at clark. he sees empathy, worry and… and something close to care.
the tears fall on his cheeks.
“why… why do you have to be like this?” lex sighs and finally moves his head back, taking in clark’s big form, his iridescent black curls. lex is looking superman in the eye when he finally admits; “your dick is too big for me. it’s hitting my cervix. painful. you satisfied to have your ego stroked even more?”
clark looks dumbfounded for a few seconds, then he blushes and tries to pull out. lex, mortifyingly, whines and hugs the man with his legs, not letting him pull out all the way.
“what are you doing!? did i say you can stop fucking me!?” lex is fuming, his face hot with anger and embarrassment.
clark licks his lips and dutifully stops. his brows furrow in question.
“you said it was painful. i don’t want you to suffer, lex.”
if it was any other situation, lex would burst out laughing. right now, though, he is exhausted, still horny as hell and determined to make it work. and he is totally not dealing with this conversation during sex.
“i’m going to tell you something, and after that you will shut up and fuck me like you did before, understand?” when superman frowns and opens his mouth not to agree, but to ask an even more, certainly, stupid question, lex raises his voice: “understand?”
“good.” lex takes a slow breath and makes sure to hold clark’s gaze. “i enjoy pain. people with whom i have sex don’t dare to hurt me. they are too horrified of what i can do to them. and these people, usually, cannot even reach my cervix with their pitiful dicks. so, clark, i need you to stop worrying about me and start putting your back into it. i can assure you, i’m capable of stopping you if you do anything i don’t like. now can we continue before another interdimensional creature will steal your attention and before i lose my fucking mind?”
“what are you waiting for, you dim alie—“ and just like that, superman shuts lex off with a fierce kiss and continues to fuck him, finally understanding the assignment.
lex’s cervix will be aching the whole week after that.
