I WAS JUST TALKING TO JUPI ABOUT TYUN'S SIZE DIFFERENCE KINK BC HE DEFINITELY HAS ONE!! NO ONE CAN CONVINCE ME HE DOESN'T HAVE ONE. my biggest thing about this taehyun is that he's normally such an articulate person, like he's very aware of his thoughts and feelings, but he just CANNOT think about soobin being sm bigger than him without losing his shit. and he can't figure out why. like if he thinks about sb's height for more than a minute he just starts sweating buckets with virtually no explanation until it gets to the point that he can't even look him in the eye, bc every time he does, he realizes he has to look UP and his brain starts going haywire. obviously soobin figures it out soon enough, and he's initially thinking that taehyun must be going through some kind of phase that's making him super insecure about his height again but whenever he tries to have a conversation about it th is just clammed up. he can't say a word and every time soobin talks about it, trying to comfort him by saying, "i'm not /that/ much taller than you, a lot of my limbs are just bigger, yk? like look at our hands, could you guess that we only have like a 3in height difference," taehyun swears it's getting hotter in the room. until eventually he realizes he's hard and it all clicks into place SPECIFICALLY BC he starts thinking about how small his dick would look while soobin held it, how soobin's hands could probably go around his waist and then some, and how soobin's cock is giant (bc ofc he's seen it, they've lived together for 5+ years). and then SOOBIN realizes taehyun's hard, mostly because he's blushing like hell while he keeps talking at him about how it's really just his legs that are longer, or that taehyun could match his size with a good pair of insoles. and then he also realizes what's been going through taehyun's head bc he's just staring at soobin's crotch. like he can't even be discreet about it, he really wants to see how small he looks in comparison to /that/, and then it's soobin's turn to clam up and blush and try not to think too hard about tyun's little hands and lips wrapped around him. it's all in vain though, bc one of them breaks eventually and they end up jerking each other off while taehyun just keeps whining about how it's not fair that soobin is so much bigger.
