“Come here, Kitten. I’ve got a nice surprise for you.” Tony pats his lap and tsks when Peter coyly turns the other way. He smiles fondly even as he firms his voice. “Kitten, don’t make me tell you twice.”

Peter perks up visibly but still takes his time crawling to Tony on all fours. His ears stay in place and his soft tail brushes his thighs as he goes, much better quality than before Tony came into his life. The plug holds him open deliciously as he slinks across the hardwood flooring without a care for his knees.

He stops and rubs his cheek against Tony’s thigh before climbing up and into his lap, legs spreading and around Tony’s thicker waist. He feels his tail slide down to the floor but Tony picks it up for him before he can reach to adjust. Peter purrs happily at the thoughtful attention and leans in to kiss him sweetly.

“Good Kitten. You’re so cute when you don’t want to listen, even when we both know you want this treat.” Tony kisses him back thoroughly enough to distract Peter from what he’s grabbing from out of his pocket. His eyes widen when he sees the collar; buttery soft leather in Iron Man red with a gold nametag. His eyes chest and groin both go hot all over. “I know it’s more of a dog thing, and I don’t expect you to want to get a leash or anything to go with, but I want my Kitten to feel special and owned whenever he wants.”

Bucky knows he’s going to get in trouble for this but he just can’t help himself. Peter was still stretched open from when Tony had fucked him last night in front of Bucky, and Bucky was instantly horny from the sight of his stretched out hole. 

Despite getting to jerk off on top of Tony’s load leaking out of Peter’s used rim last night, painting him up right after the other man pulled out, Bucky’s cock rose up like it had been neglected. 

He needed a taste.

He’s got his tongue inside and two metal fingers massaging the spot behind their youngest lover’s balls to the tune of Peter’s soft, whimpering cries, when Tony comes back from his morning shower.

“You know I’m going to have Peter put you in your cage for this.” Tony says while buttoning the cuffs to his dress shirt. Bucky moves to stop what he’s doing, to accept his punishment now, when Tony tuts sharply at him.

“Finish what you started, Peter isn’t getting punished for your bad behavior. You can’t cum but he can, as much as his little heart and cock can handle. Then you go in your cage until I take you out of it.” Tony strides over to the bed and brushes Peter’s sweaty curls aside to kiss his temple. He smirks at Bucky where his face is back buried between Peter’s cheeks and only gives him a pat on the head before heading to the door.

Bucky’s cheeks heat from the treatment at the same time his cock leaks harder between his thighs.

“Are you wearing my shirt?”

Peter isn’t sure what he expected when he came home from classes, but Tony wearing one of the silly meme shirts Peter bought off of a third party site with a 15% discount code while drunk isn’t it. 

He also isn’t expecting how hard he gets seeing Tony wearing his stuff.

“Hey, kid. Pretty sure you left this behind the other day, and, well, I am known for being selfish and greedy, so.” Tony tossed him a smile over his shoulder but didn’t otherwise look up from his tinkering at the kitchen counter. 

Why he was disassembling parts there of all places Peter didn’t know but he wasn’t about to pass up an opportunity. 

“That’s fine. I’m feeling a little greedy myself.” Peter slid into the spot behind him, pressing his hips flush to Tony’s ass while his hands slipped in front and made slow, loving, stroking pets towards his lover’s fantastic cock. He was delighted to feel Tony had hardened in the time it took his fingers to wiggle beneath the hem of his pants and wrap around the girth of his shaft. 

“This is really delicate work here. I probably shouldn’t be distracted, you know.” Tony sounded amused and his cock was only getting bigger in Peter’s hand. 

“I wonder what your girlfriend would do if she knew what you were doing right now.” Bucky growled, low and hot. The other man gave him a slightly withering look before continuing on with his day. Which apparently meant wearing tight shorts and no underwear around the compound like he didn’t give a damn who saw the outline of his cock and the swell of his ass straining the material. 

“Don’t have one of those, Barnes. Does it look like I want one with these anyway?” Now Tony seemed amused. His back was to Bucky as he made his coffee. 

Someone (Bucky) had moved Tony’s coffee grounds to the top shelf last night and so Bucky was treated to the sight of the genius getting on tiptoe and stretching up and up to reach for it. 

Bucky looked longer than he should have before finally shaking himself out of his daze. He walked up behind Tony and grabbed it with his metal hand, the flesh one landing on the counterspace beside Tony’s hip. He lowered the bag of grounds down in front of Tony so that his metal arm circled him, so close, so close, he could smell Tony’s aftershave and feel his heat and almost touch his skin.

“Here.” Bucky breathes the word behind Tony’s ear. He feels him shiver better than he sees it. A slow, devious smile breaks across his face as he isn’t pushed away. “If you don’t change out of those shorts and into some pants I’ll have them around your ankles by lunch time.”

Tony takes the coffee grounds and starts preparing his usual blend while managing not to bend over right then and there.

“ ‘How do you feel about adding another person to the mix?’ you said. ‘What could go wrong, Tony’s a horndog, right?’ you promised.” Peter whined, bent over said man’s lap with his ass in the air and bright red with hand prints. He flinches and squeezes his legs together when his mentor and brand new lover brings another heavy, perfect swat down onto his buzzing skin.

“Well, he wasn’t wrong. And your hard little cock tells me you’re loving this punishment just as much as we both are.” Bucky laughs at his lovers plight. Peter had gotten so used to being mouthy and it’s finally gotten him the spanking he’s been angling for.

Tony reaches underneath and between Peter’s thighs, forcing them apart so he could feel how hard and hot the kid was for this. He grinned, slapping the jumping skin of Peter’s inner-thigh. “But, the whining, kid. Really?”

Tony loved brats. He loved the way Peter was already opening his mouth to complain some more.

“I’m so sick of your voice. Why don’t you come over here and put your mouth to better use?” Tony pushed the panting, squirming slut right off his lap and spilled him out across the bed. He knelt above him, stroking his cock and laughing along with Bucky at the outraged, nearly scandalized look Peter gave him.
