The door swung back behind them, clicking close. Steve leaned against the wall, his arms crossed. "I knew I should've never trusted you," he mumbled. "'It'll be fun!' you said." Steve waved his arms at the closet. "I don't think this is going to be fun."
"Relax, will you?" Tony said, stepping closer to him and wrapping his arm around Steve's. Steve stared down at Tony's hand which was gripping his bicep.
Tugging his arm away, Steve said, "How can I relax when I stuck for seven minutes with you in this tiny closet?" Sighing, frustrated, he turned away from Tony and stepped towards the back of the closet. Tony came up behind him, slipping his arms around Steve's neck.
"Come on, Steve," Tony whispered. "It'll be fine."
Steve turned his head to see Tony. "Are you sure?" Steve asked a bit nervously.
Removing his arms from Steve's neck, Tony clutched Steve's shoulders and turned him around. "Of course," he whispered before forcefully pushing Steve up against the wall and thrusting his lips on his.
Steve scrunched against the wall, his hands sprawled out on it and his knees slightly bent. Tony still kept his lips on Steve's, but they were still. Steve, panicking, ducked down. Breathing heavily, he looked up at Tony. "What's wrong, Capsicle?" Tony asked him.
"I—" Steve stammered. "You—me—"
Tony grabbed his hand and helped Steve to his feet. "I know," Tony said. "But maybe this is the only time this could happen."
Steve tilted his head. "I don't know about that."
Smirking, Tony kissed him again, this time passionately. Steve timidly kissed back for a few seconds before meeting Tony with the same ferocity. Tony slipped his tongue into Steve's mouth. Steve jumped a tad bit, almost pulling away as Tony did this, but went along with it.
Tony pushed at Steve's jacket, pushing it off of him and onto the floor. Although unsure, Steve went with it until Tony started fiddling with the buttons on Steve's shirt. Steve pulled his head back, staring at Tony. "What are you doing?" Steve breathed.
He didn't say a word; instead, Tony took his fingers and finished unbuttoning Steve's shirt. It swung open, Tony slack jawed as he rubbed his hands on Steve's chest. "We need to go to the gym together more often," Tony mumbled.
Steve shivered as Tony ran his fingers across his abs. Something about Tony's touch gave Steve's goosebumps. Soon, Steve found himself pulling off Tony's shirt, forcing his lips back on Tony's again. Tony was hunched up against the wall as Steve kissed him, running his hands through Tony's hair. Tony pulled away from Steve, kneeling down a little more where he could put his mouth on Steve's chest, giving it small kisses and an occasional lick. Steve moaned as he did so.
He grabbed Tony's shoulders and pulled him up to his face where he could see him again. Steve, his breathing jagged, crushed his lips against Tony again, his hands sliding down to Tony's belt loop and tugging it downwards.
As Tony was getting ready to oblige, the door swung open. "Okay guys, your time's up," Natasha said. "I'm surprised you haven't kil—" She froze at the sight. Steve and Tony's face were pressed up against each other still, but they were looking over at Natasha. Tony's back was bent backwards at an awkward angle while Steve towered over him. Removing his finger from Tony's belt loop, he scooped up his shirt and jacket. After throwing on his shirt, he left the closet, his face blood-red as he left the building entirely.
Tony stared at the rest of the group, he were gaping at him wide-eyed. Shrugging, Tony picked up his shirt as well. "What happens in the closet stays in the closet," he said before leaving and heading upstairs.
The rest of the group had no idea what to say.
