Superwonderbat where Bruce keeps stealing Clark’s clothes anytime he can, to the point where whenever he’s at home, he is probably wearing a daily planet hoodie.
He wants to wear Diana’s clothes, too. Badly.
Not only does it make him feel guilty that he’s only sporting one of his partner’s claims, he also loves the way Diana smells and her stuff always looks so comfortable, he wants to be able to lounge on the couch with a pair of Metropolis Meteors sweats on and snuggle into that plain gray hoodie he sees Diana wear all the time, his nose in the neckline to pick up the hints of vanilla and jasmine that follow his partner.
How does he solve this problem? He pouts.
Anytime he sees Diana in anything that’s not her uniform, he heaves a big sigh as he traces the fabric, sometimes going as far and to bury his head into her shoulder or stomach as he forlornly rubs his cheek into the material.
Once, he even tried to wear a sleep shirt of hers when he was staying at her place. By the time he got it over his shoulders, he had already ripped the neckline. Diana had laughed and told him it was okay, she likes him better sans shirt anyway and Bruce had to tamp down his disappointment. It was nobodies’ fault. Diana, despite her height, is smaller than him, with his broad stature and muscle bulk brought by years of work. It’s a silly thing to sulk over, but he can’t help it.
He thinks he’s being subtle about it.
Despite being the most elusive man in the world, he has trouble keeping stuff from Clark and Diana, especially when he really doesn’t want them to know. They talk about it, it takes them less than 5 minutes to deduce the problem and less than 7 to find a solution.
Diana buys a bunch of stuff in Clark’s size, hoodies and t-shirts and pj pants, and breaks them in. She pretty much wears only her new baggy clothing for a week. Then, she’s leaves it out for Bruce. A hoodie draped over the back of the couch, a t-shirt on top of his pillow in her bed, pajama pants waiting for him when he gets out of the shower.
He knows what they’re doing, knows they talked about it, but he can’t find it in himself to be bothered. When he saw the hoodie on the back of the couch and threw it on he thought it was a new one of Clark’s until he caught a whiff of Diana’s distinct detergent. Immediately, a smile takes over his face and he noses into the collar, taking a big whiff as he falls back into the couch. When he looks up, Clark is standing in front of him with a cocky smile on his face. “Looks good on you,” he says after giving Bruce a once over. He leans down and kisses the hair sticking out of the top of the hoodie before he disappears back out the door. Bruce hides his pink cheeks under the new garment.
The first time Diana sees him in one of her t-shirts, she gets why Clark likes it so much. He’s so cute and soft and hers. She basically dives on top of him where he’s laying on his couch, kissing all over his face until he’s breathless from giggling and shoving at her shoulders. She scoops him up to carry him to bed, holding him in a bridal carry and whispering, “my baby,” before she drops him on top of the duvet. She tells Clark they’re going to bed, curling up behind him and pressing her head in between his shoulders before wrapping an arm around his chest. Clark gets there a couple minutes later, smiling broadly at the sight of his two partners curled up together and the space left for him. He changes and kisses the back of Diana’s head before lying down on Bruce’s other side, letting himself be pulled against the other man so Bruce can tuck his head under his chin. They both hear the shy ‘thank you’ he mumbles as he squeezes each of their hands that he’s holding. Clark kisses his head and murmurs, “No problem, sweetheart.” Diana kisses the back of his neck with a whispered, “Anything for you.”
