These are more of the headcanon type and not very concise but hey now ╮(ᵕ—ᴗ—)╭
In my previous post I have listed plenty of ways they're attracted to each other I suppose, but I did not get into that many details (foreshadowing). The short answer is that they like almost everything about each other they want to gobble the other up but you already know that.
Polyester is quite fond of his brother's physique. Both of them work very hard to keep up their appearances. They are twunks okay? Polyurethane's workouts mostly focus on agility, endurance and speed. He has quite the legs actually. Not that he's mid above the waist but below where his ribcage ends is built like a Greek statue and that drives Polyester crazy. Maybe he is more of an ass guy. Polyurethane flashes anything around and below that area and he folds in an instant.
Polyester associates his brother with both sharpness and softness. Polyurethane has sharp teeth and both of them enjoy it. Yet his lips are so soft the feeling lingers after touching. There's nothing quite like it. He loves the downturn of his eyes and his lower eyelashes and his pastel irises and how expressive they are when his mood shifts. His well-kept hair and fluffed up wings and smooth skin and his precise cruelty and mockery when it comes to their enemies; Polyester loves to watch him fight.
It's obvious that Polyurethane has his own unique way of dressing up, especially for special occasions too, it's more feminine but not extremely so. Polyester actually looks forward to whatever new fit he'll come up with because he's literally adorable it should be considered evil. Like literallyyy.
Polyester also secretly loves giving Polyurethane what he wants. He probably shouldn't spoil him, probably doesn't, and it can sting now and then when Polyurethane doesn't know the true depth of his feelings and what he does for him, and he should really wish for his brother's own independent growth and he does, but By God he gets electric shocks when Polyurethane genuinely asks him for something. Even if he doesn't really want to do it. Maybe even more so.
Maybe Polyurethane is a tiny bit sadistic (*whole ass lie. He is sadistic) but he does kinda dig it when his brother's troubled. He pushes his luck and as the contrary man he is he does get put off by it randomly. Sometimes. For example if Polyester is hurt especially because of him and not in a sex way either. Or if he catches a glimpse of his internal turmoil. Buuut he may or may not have a hard-on about it too. Duality of man.
Other than that, Polyurethane does think Polyester is painfully handsome in any way. Polyester is well-groomed too, just in a different way than he is. He loves the red of his older one's eyes and how fresh he smells and the silky feel of his face. So like, his brother serves face no matter if he's sleeping, fighting, just hanging out or when he's forcing eye contact in bed, telling lies, breaking in and giving Polyurethane what he wants. Uretan's for real Polyester's no.1 fan.
He loves to rile his brother up and make him jealous from time to time; Polyester is very jealous but Polyurethane is usually more vocal about it. Polyurethane has a mysterious allure that attracts glances and screams look don't touch, while Polyester is naturally more charming in a professional way that eases others into feeling like they can talk to him. Gets Polyurethane acting in some kind of way to keep his brother's attention to himself but on sunny days he kinda likes to show him off.
Polyurethane loves all parts of his brother's body but he loves loves loves leaving hickeys on visible areas the most. Also biting boney areas because they feel good under his teeth. Jaw, collarbones, hands, you name it. If he were to go for non-bony areas those would be tits or thighs. But if he were to do what he reeeeallly really wants he's biting Polyester all over. It is what it is.
Lastly, he can't tell if Polyester knows this, but simply looking at his brother's face will easily wipe off his worries. Almost to a comical extend because the world could be ending and he wouldn't even be that upset if there's no fear of losing Polyester. He can even follow through plans he shouldn't have just because Polyester's presence keeps him away from feeling bad about it. Problems with Ramie are exempt from this and if Polyurethane conflicts with his brother to a huge degree he might avoid looking at his face altogether. But it doesn't change the fact that to Polyurethane, Polyester's visage is an anchor.
If day ever comes that I have to prove I'm thinking about these seriously and not just projecting let it be the proof because you'll never see me saying im an ass guy
