Regency AU: As Tony gets more bold, he asks Steve and Bucky to act out one of the the scenes in the erotic romance novels because he wants to try it out or because he doesn’t think that position is possible
(A note: Tony still tries to read his erotic novels in private despite the fact that he knows his husbands know about them. He is super embarrassed at being found out because of Sarah saying they were secret books and even though he’s realized that was just to make him feel comfortable/safe the feeling that they should stay secret doesn’t leave him.)
Tony only goes to them because he thinks it’s completely ridiculous. Totally inaccurate. He can’t even believe something so hilariously wrong got published, and he’s a little disappointed because so few of his erotic novels have triads like he does and this one is so blatantly wrong–
“It’s called ‘double penetration’ and it’s perfectly possible,” Bucky says.
Tony squawks and flees the room. Steve and Bucky stare after him, concerned. Tony usually flees when he’s embarrassed but this time had seemed different.
(It’s because he didn’t believe them and thought he was being made fun of and he was hurt. Then he recalls that Steve and Bucky have literally never lied to him (at least about these things) and he has to take a moment to just–consider, this is–how?? The human body can only take so much–
“Peter’s head was bigger than my husbands’ dicks,” Tony says to himself, or so he thinks. Happy stares at him and then slowly leaves the room. Pepper looks horrified. Tony doesn’t notice.)
“Have you ever wanted to do that to me?” Tony blurts out.
Steve looks up from a sketch he’s doing of Bucky, blinking slowly. “Honey, there are lots of things I want to do to you. You’re going to have to be more specific.”
Tony blushes and looks back down at his needlepoint, mumbling to himself. Steve stares at him a bit longer before returning to his sketch. “…I meant have you ever wanted to do… that. Where you’re both inside me,” Tony finally whispers, and then feels so embarrassed that he wishes he could disappear. Steve doesn’t hear him because he’s focusing on his sketch, but Bucky does, and he falls off the couch, he’s so shocked. Tony lets out a little ‘eep’ and stands up to flee.
Steve catches him before he can get out the door, more out of instinct than anything (and also because he’d heard, in the background, Bucky blurting out ‘don’t let him leave!’). He turns Tony around in his grip but Tony won’t look up at him, too embarrassed, too scared. “Just–Just forget it, Steve, I–”
“Shh, honey,” Steve whispers soothingly, thumbs rubbing little circles into his arms, and Tony unconsciously relaxes, at least a little. When Steve lifts a hand to cup his cheek, he leans into it, eyes fluttering shut, “Don’t be so embarrassed. We’ve got you.”
Bucky sidles up beside them, nuzzling the back of Tony’s neck. “You shouldn’t be afraid to ask us questions, sweetheart.”
Bucky eventually cajoles Tony into repeating the question. He mumbles it into Steve’s chest, too embarrassed to lift his head. “Have you ever wanted–or, um, considered, um. Being inside me. At the same time?”
Steve swears softly before dipping his head to press kisses against Tony’s ear and neck. “Honey–and I don’t mean for this to sound flippant or rude–of course I’ve imagined both of us fucking you at the same time.” Tony lets out another embarrassed little “eep!”
Of course, now that he knows they’ve both thought about it, he feels obligated to let them do it.
“That is exactly why we haven’t told you,” Steve deadpans, and then leaves to go take care of something his mother had wanted him to do.
Tony watches him leave fretfully before looking up at Bucky. “Was–was that wrong?”
“Honey,” Bucky sighs, eyes going soft, and reaches out to cup the omega’s cheek. “We don’t want you to do things for us because you think you have to. We want you to do it because you want to. Steve’s never going to do anything to you if he even thinks you’re only doing it for him. And the same goes for me. If you decide it’s something you want to try, great! We’ll try it. If you’re only doing it because you think it’ll make us happy, then you don’t really want to do it, and we’d feel awful when we realized it. And we would realize it, eventually,” he adds, because they would–Tony doesn’t know it, but he always gets this expression when he’s forcing himself to do things he doesn’t like, his jaw going tense and the smallest furrow appearing on his brow. Those things are few and far between! But they still happen enough that Steve and Bucky can recognize it easily.
“Oh,” Tony says, and then leaves to mull on this information alone.
(Rhodey approaches Steve and Bucky silently, holding a large book. He beckons them to lean down. Steve and Bucky do so obediently. Rhodey nearly knocks them out with how hard he hits them before he turns and silently rolls away.
“I think Tony might have talked to him about the double-penetration,” Bucky says when he blinks the stars away from his vision.
Steve turns to glare at him. “You think?!”)
Finally, though, Tony skitters up to them after supper one night, all nervous and anxious. Steve spreads his arms so Tony can hide his face in his chest and runs his fingers through the omega’s hair soothingly as Bucky flops against the both of them.
“Something on your mind, sweetheart?” Bucky asks softly.
Tony grips Steve’s shirt with white knuckles as he mumbles into Steve’s chest. “I want–I want to try it. With both of you.”
Steve and Bucky look at each other for a long moment before looking back down at the omega fondly. “Alright.” Tony shivers in response and ducks further. It doesn’t stop Bucky from watching the back of his neck flush. He presses a kiss to it just to hear Tony mew.
They’re fingering him when Tony gets that face–the jaw going tense, the furrow appearing on his brow. They slow to a stop in concern. “Honey, what’s wrong?” Steve asks, because Tony had seemed like he really liked the idea when they started.
“I was just–your knots are going to really hurt, aren’t they?” Tony asks, voice trembling.
Steve and Bucky stare at him, flabbergasted, before Steve finally just sort of bellows, “NOOOOOO.”
They are not going to knot him at the same time. No. That’s not a thing. One of them is going to pull out. Two knots won’t even fit.
“My dick hurts at the very idea,” Bucky admits helplessly.
“Oh,” Tony says, looking super embarrassed, and they’re pretty sure the only reason he doesn’t flee is because they still have their fingers inside him.
“Did. Did they do that in the book?” Steve asks awkwardly. Tony makes kind of a drawn-out ‘eh’ sound. “Oh my God. Sweetheart, no.”
However, Tony seems a lot more interested in what’s going on now that they’ve cleared up the misunderstanding. They’re opening him up slowly and very, very carefully, and all he can do is writhe on their fingers and whine “please” and “more” and “I’m ready” and clutch at them helplessly. Finally he whines and wraps his arms around Bucky’s neck, squeezing his eyes shut and breathing out “oh, oh, oh”s as he comes on their fingers, trembling, before going boneless under them, riding his afterglow just like they’d told him to.
Steve and Bucky hurry to take the time to stretch him more while he’s totally relaxed, and his body responds beautifully, all hot and slick and wet and open. “So sweet for us, honey,” Steve sighs into Tony’s ear, and he has just enough awareness to shiver pleasantly and turn his head for a kiss.
Steve slides in first, fingers shaking as he clutches Tony’s hip. All he wants to do is fuck into Tony but he waits, and it’s one of the most difficult things he’s ever had to do, so he distracts himself by peppering the back of Tony’s neck and shoulders with kisses. It takes some maneuvering for Bucky to position himself, and eventually Steve just pulls Tony’s leg up and against his chest to keep it out of the way.
Tony whines into Bucky’s chest as he starts to push into him but tries desperately to stay relaxed. They whisper reassurances to him but he mostly calms himself down with the rationalization that his husbands have never, ever hurt him and would probably cut their own throats before they did anything that could, and that if he asked to stop, they would immediately, no questions asked.
“Full,” Tony whines when Bucky’s settled.
“Too full?” Bucky asks gently, helping him lower his leg.
Tony squirms experimentally and then tucks his face against Bucky’s chest again. “Just–just a minute.”
“We’ve got all the time in the world, sweetheart,” Steve says, voice strained.
Tony whines again as Steve’s hand slips from his hip to rub small, soothing circles against his stomach. “Are you–are you guys okay?”
“Tony,” Bucky chokes out, burying his face in the omega’s hair as Steve chuckles weakly behind him. “Honey, we’re fine. We’re just waiting for you to say you’re okay.”
“Oh,” Tony whispers, shifting again and wincing when Steve and Bucky both make these wounded noises. “Sorry.”
“It’s fine, honey,” Steve babbles. “You just–do your thing, we’re fine.”
Do my thing? Tony thinks, bewildered, before tucking his face against Bucky’s neck and clenching down a little, just to–just to see–
“Fuckfuckfuck okay sweetheart we’re trying really hard here please don’t do that,” Bucky says quickly, hips twitching against his will.
Tony jerks his head back with a mewl as the movement shoots sparks up his spine. “Oh!” Steve and Bucky freeze, terrified, but Tony just squirms a little more, finally pressing down on them further and letting out needy sounds. “Yes, okay, yes!”
Steve and Bucky watch him carefully before they start to move, slowly and gently. Tony jerks his head back with a moan and nearly bonks Steve in the face with it. “Holy shit,” Bucky says, humor in his voice, as Steve takes a moment to gently direct Tony’s head over his shoulder so that he doesn’t just fucking concuss them both.
It takes a while to find a good rhythm, and Tony doesn’t make it any easier with his squirming. Bucky finally pulls Tony’s leg over his hip so he has less leverage to move and that seems to do the trick for them, having him stretched between them, leg over Bucky’s hip and head over Steve’s shoulder. Tony’s slick and hot and the wet sounds their cocks make as they draw out of and thrust back into him are absolutely obscene, and Tony whimpers and bites his bottom lip in embarrassment, but they don’t let him demur, whispering praise and encouragement to him.
“Feel so good for us, sweetheart,” Steve murmurs into his ear. “So hot and tight.” Tony mewls and turns his head to press a kiss to Steve’s jaw, overwhelmed beyond words.
“Whose knot do you want, honey,” Bucky asks gently as Tony scrabbles at his shoulders. “You want my knot? Or Steve’s?”
“Yes,” Tony answers desperately.
Steve hides his amused smile in Tony’s throat as Bucky snorts. “Can’t make a decision, sweetheart?”
“Please,” Tony whines. “Please I need it!”
Bucky raises an eyebrow at Steve before smiling a little. “Alright, sweetheart, we’ll give it to you.”
Tony whines again, ending in a high-pitched keen as Bucky pulls his cock free. Then he lets out a guttural sound as Steve presses his knot in, eyes wide in shock. “Oh.”
Steve rolls his hips a few times until Tony whimpers and tries to squirm away. “Sorry, sweetheart. You still a little over-sensitive?”
Tony grips the sheets with one hand, tight, and lets out another whimper. “Oh, oh, oh…!”
Steve rubs gentle circles on his stomach again. “Shh, sweetheart. We’ve got you.”
“We certainly do,” Bucky answers, shimmying down the bed so he can get his mouth on Tony’s cock.
Tony screams, sheets twisting in his hand, the other going back to clutch at Steve’s hip, and then he shakes and shakes and shakes as he finally comes. Steve grunts at how tightly Tony clenches around him, wrapping his arm tighter around Tony’s waist. Tony babbles something but neither of them really understand it, but they figure that’s okay because then he murmurs both of their names so sweetly that they have no choice but to kiss the words from his lips.
“Was that okay,” Steve asks Tony gently once he’s calmed.
Tony’s eyes flutter open before he lets them drift shut again, eyelashes fanning over his cheeks as he breathes out a ‘yes.’
Bucky brushes his thumb over Tony’s cheek gently. “You took that like a champ, sweetheart. Next time I’ll knot you, okay?”
“C’n knot me when Steve’s done,” Tony offers tiredly.
“Aw, that’s sweet, honey, but I already came all over your thighs,” Bucky answers gently.
Tony makes a confused sound and looks down to find that there is, indeed, quite a mess all over his thighs–although a lot of it looks like his own. “Oh…”
“I liked doing it,” Bucky admits, stroking his thumb over the omega’s cheek again. “Just rest, honey. I’ll go get something to clean you up.”
“Okay,” Tony answers, sinking back against Steve with a sigh. Steve and Bucky share an amused look before Bucky gets up to get a damp cloth to try and clean him up.
(“Is something wrong with Anthony?” Sarah asks in concern when he doesn’t come down to breakfast. “And where’s Steven?”
Bucky blushes a little and doesn’t look up from the tray he’s putting together. “Anthony’s feeling a little under the weather. Steven’s tending to him while I get breakfast.”
Sarah gives him a long look. She knows he’s lying but if James Barnes is blushing she really doesn’t want to know the truth.)
((“Oh,” Tony moans, clutching his pillow closer to his chest. “Steve.”
“Sorry, honey, but I’ve gotta do this,” Steve says, frowning, as he rubs his hands over Tony’s lower back. “You’re gonna cramp up if I don’t.”
“You’ve split me in two, you neanderthals, you–you beasts. Oh, Steve, not so hard, please.”
Steve winces but continues rubbing. “Sorry, Tony,” he repeats quietly. “We don’t have to do this again.”
“But I want to do it again!” Tony snaps, turning to glare at him. Then he whimpers and turns forward again. “Ow. Just–maybe not soon.”
“Holy shit,” Steve blurts out in response.
“Steve! I said not so hard!”))
