nearly four years the two had been together. pretty much the whole world knew. nearly four years and yet something bothered Tony. the went to bed together every night, that the two actually went to sleep, and most the time he'd wake to find Bruce on the floor, huddled in the shadows snoring, or on the couch, facing away from the bed. it hadn't bothered him at first, thinking it'd been a while since Bruce had someone to lay with and he wasn't used to it, but nearly four years later and the man still did it. Tony was starting to doubt their relationship. he cast a glance over at Bruce, who rubbed his eye's tiredly. maybe it was nightmares? maybe he still had nightmares about the Hulk, who he now knew to be good and misunderstood, from back when he thought Hulk was bad? maybe he had nightmares and was afraid he'd wake Tony with them so he slept some where else?

"Bruce?" Tony ask. Bruce looked over tiredly.

"yeah?" Bruce ask.

"you look tired... did you have a hard time sleeping last night?" Tony ask. Bruce nodded slightly.

"yeah kinda." Bruce replied.

"was it nightmares?" Tony ask. Bruce looked confused, where the hell was this coming from.

"no, actually. you're a serious blanket hog. I got cold." Bruce shrugged.

"if you were cold you would've slept on the couch, not the floor, the floors colder then the bed." Tony said.

"Jarvis warmed it up for me." Bruce shrugged slightly. now he was watching Tony. there was something on his mind and he wasn't going to outright say it apparently, but it appeared his answer had made it worse. "Tony whats wrong?" Bruce ask.

"nothing." Tony replied, turning back to his work station.

"thats bullshit and you know it. I've known you for five years. I can tell when something is bothering you, so spill." Bruce said.

"how long have we been together Bruce?" Tony ask. Bruce raised an eye brow.

"it'll be four years in about two months." Bruce replied.

"so if something were bothering you, would you tell me?" Tony ask. Bruce was even more confused now, but nodded.

"yeah of course I would." Bruce replied.

"and there's nothing wrong? nothing you need to tell me?" Tony ask. Bruce thought for a few minutes then shook his head.

"no not that I can think of." Bruce replied. Tony turned.

"then why don't you sleep in bed with me?" Tony ask. Bruce's eye brows shot up, so thats what this was about. he rubbed the back of his neck.

"oh, that." Bruce muttered. Tony nodded. "okay you're going to think this is super stupid and I know your self-conscious, but I can't sleep with the light." Bruce replied. now it was Tony's turn to be confused.

"huh?" Tony ask. "light? why don't you ask Jarvis to dim it? but wait, our room is usually pretty dark." Tony said. Bruce rolled his eyes and tapped Tonys chest. Tony paused, then it sank in. "oh, that light." Tony muttered.

"yeah, when it's dimmed by your t-shirt it's not so bad, but when its not I can't sleep." Bruce admitted.

"why didn't you just say something. I can wear a shirt to bed." Tony shrugged. Bruce shrugged back and Tony chuckled taking his hand. "come on, its time for bed. you look exhausted." Tony chuckled. Bruce grave him a sheepish smile and followed him to bed. Tony kissed his forehead and smiled, holding him tightly. Bruce buried his face in Tony's shoulder and smiled, yawning.

"this is two nights in a roll we've gone to sleep." Bruce murmured. "at the same time." Bruce chuckled. Tony laughed softly and kissed Bruce's cheek, running his fingers through Bruce's hair gently.

"yeah well apparently you didn't sleep you well, you wouldn't make our usual week or so." Tony chuckled. Bruce nuzzles his face into the crook of Tony's neck murmuring happily.

"your shirt is still kinda bright." Bruce muttered. Tony frowned.

"then roll over and face away from it, because I'm cuddling you tonight, like it or not." Tony muttered. Bruce laughed and rolled over to let Tony spoon him. Tony watched his lover drift off to sleep. as soon as Bruce was good and asleep, he got up. he wasn't sleepy and he had something he needed to fix.

*next morning*

Bruce woke up and stretched, surprised not to find Tony next to him.

"Tony?" Bruce ask, looking around the room. "Jarvis, where's Tony?" Bruce ask.

"sir has stepped out for a moment." Jarvis replied. Bruce raised an eye brow, getting up. he headed downstairs.

"hey Bruce you look like you slept good." Natasha said. Bruce nodded grabbing a cup of coffee.

"yeah. I didn't have to curl up on the floor to escape the light of Tonys reactor, best sleep in a while." Bruce admitted. she nodded. "speaking of, have you seen Tony? he was gone when I got up." Bruce said.

"yeah he left about ten minutes ago, said he had to go pick something up." Natasha replied.

"Tony had to go get something?" Bruce ask, eyebrows raising quickly. Natasha shrugged. "Tony has people to do that stuff for him. Tony doesn't just go run an errand." Bruce said. Natasha shrugged again and went to eat her toast. Tony came back a few minutes later.

"oh hey you're up." Tony smiled. Bruce crossed his arms over his chest.

"alright Mr., what are you up to? you don't simply just run errands." Bruce said. Tony gave him a grin, kissing him deeply.

"why don't you come with me and find out." Tony said, giving a shit eating grin as he grabbed Bruce's arm. Bruce yelped as Tony pulled him along. he pulled him right back up to their bedroom. then let go, pulling a shirt from his bag. he tossed his other aside and pulled the knew one on. even Bruce could tell the shirt looked different. "Jarvis, cut the lights and close the blinds." Tony said. Jarvis cut the lights, close the blinds, and it was completely dark. Tony grabbed Bruce and pulled him close. Bruce swatted at his hand. "just me love." Tony smiled. "like it?" Tony ask.

"I don't understand." Bruce replied.

"I spent two hours last night, personalizing seven shirts to the exect calculations to keep my reactor from keeping you awake." Tony explained. Bruce smiled and pulled him closer, giving him a deep kiss. Tony smiled and kissed back.

"thats sweet." Bruce muttered. "but why would you waste money like that Tony?" Bruce ask. Tony shrugged, resting his forehead against Bruce's.

"you didn't like my nightlight." Tony replied. Bruce smiled, brushing his lips against Tony's.

"I love you." Bruce murmured.

"I love you too." Tony grinned.
