Chapter Text
“Tell me,” Damian pants, mouth wet and red, eyes glazed over in heated fugue, “a story.”
By a story he means a fantasy. This is a game they’ve played since Damian’s first heat, the younger omega clinging to Dick and sobbing because of how much he hated the feeling of an artificial knot inside of him. Dick is the only person who has seen Damian like this, soft and pleasure filled and tortured by the seemingly endless waves of his heat. When he’s extra overwhelmed — usually near the end of his heat when Dick’s has already broken and can’t quite keep up with his brother’s appetites — boiling alive and too sensitive to really give in to his own needs, he asks for a distraction.
Damian asks Dick to tell him a story and for over two years now during their once a month heat Dick has spilled just about every fantasy of his that he can reach for. Not that he’s un-imaginitive or anything, but as a partner — even outside of heat — Damian is very giving and always up to fulfilling Dick’s fantasies or spur of the moment needs. It’s pretty difficult to come up with a new and exciting fantasy when you’re sexually exhausted and your partner has no difficulties meeting your needs.
“I don’t think I have any stories, baby,” Dick breathes, shifting to take some of the weight off his shoulders which has the added effect of Damian tightening around where DIck’s fist is simulating a knot within his cunt.
The younger omega mewls, wetness building at the corners of his hazy eyes. His cock drools against his navel and his thighs clench around Dick’s arm as if fearing his lover will remove his hand before he’s ready. He still hates artificial knots but Dick being an omega this is the closest they’ll ever get — not that either of them minds at the beginning and middle of their heat.
“Why don’t you tell me a story, hm?” Dick asks, carefully maneuvering one of the damp cloths they have prepared to wipe at the other omega’s sweaty, flushed face. “We’ve done a ton of mine, baby. I think it’s your turn.”
Damian pulls his bruised bottom lip between his teeth, hissing slightly when he puts too much pressure on it. Dick immediately moves to thumb the lip out of his brother’s mouth, wiping it with an unused corner of the cool cloth. Those green eyes are so unfocused it’s as if they’re looking through Dick which isn’t super uncommon for the last few hours of the younger man’s heat.
“My turn?” Damian questions.
“Yeah, Dami. Tell me a story,” Dick coaxes, running the cloth carefully over chafed nipples and bitemarks he left along the younger man’s torso when he was deep in the throes of his own heat.
Damian seems to drift for a minute, still not quite relaxing around Dick’s wrist but something in him slotting into place. “Did you know, in the League,” Damian takes a hitching breath, the kind that someone second guessing themself would make.
“In the League,” Dick prompts, truly wondering where this was going even though he didn’t expect the League of all things to be brought up in their heat nest.
“In the League,” Damian repeats, swallowing, “omegas are used freely.”
Some kind of alarm bell goes off in Dick’s head over the statement, the kind that any normal person would have. The kind of mental red flag that starts flapping in the wind any time Damian or Jason brings up something to do with the League. Dick would immediately grab onto that flag and start waving it to the beat of that alarm if not for the outright reverence laced in Damian’s exhausted, heat-addled voice.
“Outside of heats and missions when an alpha was not liable to have their face torn off for the offence,” Damian says, voice coming a little easier as he immerses himself in what he’s saying, “any alpha who had proven themself and passed training could take an omega no matter the place, time, rank.”
The younger omega licks his lips. “Before I came to Father — before I even presented — I knew due to my anatomy that I would be an omega… it was the only thing I genuinely coveted about the designation.”
Dick’s cock twitches against his own thigh and his cunt starts to slick up even with the troubled tangle of feelings swirling around in his chest at Damian’s words. The older omega shifts his hand a little, seeing if Damian is ready to let go of the “knot” yet but the other omega is still milking it. He always needs it longer than Dick does.
“You wanted that?” Dick asks, voice soft and as non-judgemental as he can possibly make it. “Just any old alpha bending you over at their discretion?”
Damian snarls, eyes going sharp like acid for a moment, walls tightening around Dick’s hand. “Trusted alphas, proven alphas. If some plain, useless knothead ever attempted to touch me–”
“Okay,” Dick interrupts carefully, fingers sliding up to trace his refreshed mating bite on Damian’s scent gland, “okay, Dami. C’mon baby, continue your story.”
The younger omega is slow to cool down again, nostrils flaring, fangs bared. Damian is always a hair trigger away from threatening any given person in a room, but with the heightened emotions of a heat it gets worse. Hence why — after that first time anyway — Dick and Damian don’t have their heats at the manor.
“I wanted,” Damian breathes after a long few moments of intentionally calming himself, “more than anything, that freely given touch. I used to watch as other omegas… other members of the league would be allowed casual touches, be allowed such freely given pleasure…”
Damia’s walls flutter and unclench slightly from Dick’s fist, allowing the older omega to slowly extract his hand from the younger as the room once more fills with the rainy summer smell of Damian’s pooling arousal. He uses the rag to wipe his hand down, eyes still trained on his brother, the way his flush has made its way down to his chest and the way his pulse has clearly spiked under his dark skin. Usually this arousal has been called forth by whatever filthy thing Dick has brought from his own mind to pull Damian’s system back towards arousal rather than knot-milking.
“They were allowed to be used,” the teen says, that slight tone of reverence back in his voice. “Could be filled up and sated at any point of the day, in any room, with any other person around.”
Dick is definitely contributing to the aroused scent curling in the room. His own honeysuckle scent gets thicker as the other omega loses himself in the fantasy, in the memories. He shifts, sliding down to where he can shoulder between his brother’s rubbing thighs.
“I once witnessed two omegas being used in the middle of a meeting I had been forbidden to attend,” Damian tells him, moaning softly as Dick rubs his cock over his brother’s loose, well-used hole. “Every alpha in the room took their turn with them, filled them and left them dripping and used on the table.”
Dick presses into his brother, the other omega moaning and arching into the thrust in such a liquid, wanting way it almost feels unreal after how exhausting his heat has been. Usually at this point Dick would be riding him carefully or jerking him off to try and help him through the last wave or two, but this fantasy — memory, whatever — seems to have taken its hold on both of them.
“Keep going,” Dick encourages as Damian’s legs lock around him and his fingers dig into the older man’s shoulders to draw him closer.
“I would stray after my training, seek out dark corners thatI knew others frequented,” Damian admits, moaning sharply as Dick hits his oversensitive sweet spot. “Other omegas would walk down those halls, sometimes multiple times, in hopes of being caught and used, and I would watch when they were finally caught, pressed against walls and over benches, held down against the floor.”
“You want that, baby?” Dick pants, nosing his brother’s scent gland where it’s absolutely pumping out waves of arousal. “Want Bruce or Jay or Timmy to push you down in the manor’s front hall and fuck you into the floor?”
Damian’s eyes roll back as he gushes through an orgasm untouched, the strongest yet of his entire heat. He’s shaking, crooning high in the back of his throat. His nails are drawing blood from Dick’s shoulders, his inner walls milking the other omega for all he’s worth.
And alright, yeah, Dick is into it. He’s spilling inside the other omega, digging his fangs into the scent gland and the mating bite that he’s already refreshed once this heat. He’s thinking about how good it would be to watch Jay throw Dami’s legs over his shoulders in the lounge and just go at it, or Bruce bending the young omega over the Bat-computer’s console, or Tim pushing the younger Robin down on the floor to take him right there in front of god and everyone.
He’ll have to be the responsible one this time. Usually Damian corners him after the heat finally leaves both of their systems, either in the shower afterwards or when they’re eating their first hot meal in two days. He’s always calm, respectful, and always tells Dick about how it’s okay if something is just a fantasy. Dick has to do that this time, Dick has to be the one to reassure his brother and tell him it’s okay if it is just a fantasy, but even more important than that Dick needs to tell Damian that it’s okay if he wants it to be more than a fantasy.
He’s already compiling a list of alphas in his head that Damian respects or trusts and it’s a short one. A truly easy list of possible alphas to gather in the manor for one day to actualize the teen’s longstanding free-use fantasy that he’s kept locked away deep inside. Their three family alphas and Jon are the only ones that Dick can think of that he would be okay with his mate sleeping with… perhaps Slade if it wouldn’t send Bruce immediately over the rails. Better not, he decides less than a minute later.
Damian’s fingers tangle in Dick’s hair as the older omega lets his weight go heavy and lax on top of his mate. “Love you.”
Dick buries his nose against Damian’s abused scent gland. “I love you too, Dami.”
