"Tony, do you have that update on the—" 

Peter whimpered at the realization that they'd been walked in on again. He went down to his elbows and buried his face in his arms, like if he couldn't see Steve, Steve couldn't see him.  

Of course that didn't work. It never did. That knowledge made his dick drip, and caused Mister Stark to moan as Peter clenched around him. 

"C'mon, don't leave the door open, Capsicle," Mister Stark said, stilling inside Peter but not pulling out. 

Peter was certain Mister Stark had nothing against the door being open, and just wanted an excuse for Steve to come closer. 

Mister Stark had made it very clear before they got involved that he had certain…tastes. Even if Peter had minded, he probably would have just dealt with them anyway. But he'd quickly discovered that even though Mister Stark's tastes might embarrass or frustrate the hell out of him…Peter still really liked them. 

Maybe too much. He often wondered if his obvious enjoyment wasn't enabling Mister Stark to be even bolder.

One of the things Mister Stark liked was for people to know Peter was his. He liked showing Peter off when he could—which was anywhere the press wouldn't hear of it. And he never locked the door or had F.R.I.D.A.Y. frost the windows when they had sex, no matter where they were, at least in the Tower. 

Peter heard Steve sigh, but felt the air shift as he moved closer. 

"Hands and knees, cupcake," Mister Stark said, giving Peter's nipple a pinch. 

"Oh!" Peter cried, pushing back up onto his arms and trying not to look at Steve, but still seeing him in his periphery. 

He couldn't help but gasp as Mister Stark started fucking him again, slowly, like he wasn't in any hurry. 

Peter could feel Steve's eyes on him as Mister Stark used him, and if it weren't for the cock ring Mister Stark had put on him earlier, he probably would have come. 

Peter bit down on a whimper. 

"He still gets embarrassed when people walk in, isn't he cute?" Mister Stark stage-whispered at Steve. 

"Tony, what is that? " Steve asked, sounding exasperated. 

Peter couldn't tell what he was looking at, but—

"Cock ring?" Mister Stark said, and Peter whined, realizing Captain America had been looking at his dick. "He comes too fast without it," and Peter got the impression of a shrug. 

Steve sighed. 

"When's the last time you let the kid come, Tony?" 

"Oh, about…three—?"

"Four," Peter interjected quietly. 

"—days ago," Mister Stark said, sounding unsure. 

There was silence for a moment and Peter wondered what look they were sharing, but was too embarrassed to look over and check. 

"Tony." Steve reprimanded. 

"What?" Mister Stark said defensively. "He's mine, I'll do what I want with him."

Peter shivered at the possessive entitlement in Mister Stark's voice and felt himself leak. 

Steve sighed again and Peter could feel the disapproval in it.

"Can I touch him?" Steve asked. 

Peter felt his arms grow weak and start to buckle. Steve was asking Mister Stark, not Peter. 

Fuck that was hot. 

"Sure, just don't make him come," Mister Stark said casually. 

Steve ran two fingers up Peter's dick, through the pre-come he'd been leaking, before rubbing at the head a bit. Peter had to close his eyes and breathe through his mouth, trying to hold back. It felt incredible after being on edge for days, and Peter wanted to come so badly, but then—

The touch was gone. 

"Look Tony, he's dripping," Steve said, as if trying to talk sense into him, apparently showing the evidence to Mister Stark. "Give the kid a break."

Peter wondered what was wrong with him that having his dick touched just to prove a point rather than pleasure him, was making him pant with lust. 

Mister Stark made a noise like he was pretending to think about it. 

"Nah, he's good like this," he finally said. "Hand me that plug, I'm almost finished."

Peter whimpered, knowing it was about to end and he'd be left like this. Again. 

"Yeah, you like it when I fill you up, don't you sweetheart?" Mister Stark said, leaning over Peter's back and running his hand possessively over the inside of Peter's thigh, his voice deepening with his thrusts. 

Peter couldn't help but nod. 

"Have fun, Tony," Steve said sarcastically, apparently giving up. "Dinner's in five."

"We'll be there," Mister Stark said confidently, speeding up his thrusts. 

Which meant Peter would be plugged and full of Mister Stark's come during dinner, and Steve knew, which meant by the end of the night everyone would know. 

And Peter was still hard and wet. 

It was going to be a long night.
