It was a normal day in the helicarrier; Tony and Bruce going about working on projects in the— very extensive, to say the least— lab while the others went about training or watching over the God of Mischief just in case he got into any, well, mischief.
Tony never had time to sit down and eat, none of them never really did. Everything was always quick and on the go as they walked in the halls or, in the men in the lab's case, in the middle of working. Tony usually snacked on things such as blueberries and smaller fruits while Bruce barely snacked. Occasionally, though, Bruce would take what Tony had offered to him, and it was only recently he was eating it right from the other's hand.
At first, Tony was a bit surprised when the other man just leaned over and bit the strawberry which he offered in between his lips softly, pulling away just to leave the leaves and small stem of the snack. His lips had brushed the mechanic's fingers slightly as he pulled away and chewed, though he didn't say anything of it; only thanking Tony for the treat and going on with his work.
Today, though, Tony actually brought it a full sandwich. Bruce couldn't help the way that his stomach growled at the sight of it; he hasn't even since the night before and he hasn't gotten time to grab something on the way to the lab.
"Want some?" Tony asks from his side of the table, holding up half of sandwich, having eaten the other half.
"That would be great." Bruce smiles back at him, and of course, Tony rips off a piece and holds it out only for Bruce to take it between his lips once more, chewing slowly and swallowing a few seconds later. A content sound rises from the back of his throat and opens his mouth once more, awaiting another piece of the food. And of course, Tony rips off another piece and feeds him by hand once more.
This goes on until the meal is finished, and Tony rubs his hands together so there's no stray crumbs on them when he goes back to work with the beakers. He had to admit, the feeling of the other scientist's lips brushing against his fingers while he fed him made a warm tingle wash over his skin, and he swore that he saw a blush tinging the other's cheeks before he went back to his work.
He planned on bringing another sandwich tomorrow.
