i'm a firm believer that all superheroes have size kinks and they all look a little different for them
hal jordan is gross about it, almost objectifying with every single thrust. he's traditional, masculine in a way thats intended to make you feel safe, an older guy just around to protect you right up until the moment he gets inside of you. "so fuckin' tight... sweet little thing just sucking me in... beggin' for it" he manhandles you in the rough way, shoves you down and lifts you up whenever he wants, hand on the stomach when you're moving too much "stay fucking still, not tying you up right now"
clark kent is so sweet about it, you can tell he means well and his sense of security comes from him putting your needs over his own. unlike hal, his size kink is almost pure amazement. the blush on his face while he watches you take every inch of him. he's gentle in moving you, gentle in his thrusts "gosh, you're taking it so well honey... gonna take such good care of you". honestly, you probably don't even realize he has the kink until he presses his palm against where he's thrusting "it's right there isn't it baby? didn't think it'd fit all the way up there"
with bruce wayne i feel like it's a little different, it's more subtle. he doesn't mock you the way that hal does, its simply something that's in the air. he'll pin you up against walls, he keeps a hand on your throat or deliberately on your ass just to see how it fits. it's a little bit of an ego thing, the playboy in him knowing that he was always going to be stronger, always able to have you how he wants. "you just stay right there pretty... i'll hold you up" also def likes to hold your jaw just to see how big his hand is compared to your face
