Summary:

For Hemlock's birthday, Ivy kidnaps Nightwing so the two of them can spend a lovely day together. She doesn't ask Nightwing though, nor any of the Batfamily for that matter.

-------------------------

Pt 2 of AU where Jason is Poison Ivy's protege, and is in a messy messy situationship with Nightwing.

Notes:

I think it's becoming a trend that every time I write a new AU i have to follow it up with at least one sequel of worldbuilding lmao

I wrote this in response to ppl asking for jason making nightwing his property following the first installment of this au!! This ended up being very self indulgent on the fluff side and less on the kink side (tho still quite kinky). I hope you like it <3

(See the end of the work for more notes.)

Work Text:

The morning filters through the foliage, casting little rivulets of light on the grassy bed Jason is laying on. He hums pleasantly as he can feel his body soak in the warm sun, coaxing his cells to awaken and energize. He opens one green eye, and smiles at the face in front of him, reaches a lazy hand up to caress it.

Nightwing is beautiful. With his dark hair and lashes and handsomely sculpted features, he looks like a prince who has been cursed to eternal rest after pricking himself on an enchanted thorn. His naked chest moves in a steady rise and fall. 

Jason sits up slightly, still keeping touch with Nightwing’s face. He runs a hand through his hair. “Wake up, my love.” 

Almost instantly, Nightwing’s blue eyes open. He ganders at his surroundings before his gaze rests on the bed companion sitting next to him. A languid, indulgent smile spreads across his face. Locks of dark hair fall artfully across his face. “Good morning.”

“Did you sleep well?” Jason asks.

“All thanks to you.” Nightwing replies. His expression is so soft and tender that Jason can’t help but lean down and press their lips together. As he does so, the branches in the canopy move to shield them from view, giving them the privacy that lovers deserve. 

Their kiss starts off chaste and sweet, before growing heated. Jason licks into Nightwing’s mouth, feeling the man open up underneath his kittenish licks. The vigilante’s strong arms wrap themselves around his waist, shifting their positions so that Jason is now lying on top. Nightwing’s hands reach down to grab at his ass. His finger skims the edge from his hole, wet and loose from last night.

Jason moans into the kiss, rocking back into the touch. He can feel Nightwing’s interest stirring as well, as evidenced by the growing tent in the blanket. It stokes a heat inside him, seeing Nightwing want him like this, the vigilante’s body reacting in response to Jason’s motions, what Jason is doing to him. Only Jason can do this to him.

Only Hemlock.

He’s already slicked up so it takes very little effort to paw the duvet off of them and slide himself onto his favorite ride. Nightwing arches up to meet him, pressing into that velvety soft inside and making them both moan. They fit together perfectly— through practice and instruction, Nightwing knows exactly where to angle his hips so he can grind against Jason’s sweet spot, make his thighs tremble and his vision burst out into stars.

He knew Nightwing was a fast learner, but it’s exquisite to see it in action. 

A few more thrusts has Jason whimpering, curling in on himself as he feels the pleasure ramping up. He’s still so sensitive from all their love-making last night, and he can feel his walls flutter around the cock like they’re unsure if they want to get away from the stimulation or if they want more. Nightwing notices it and makes his thrusts accordingly shallow, so that his cockhead just rubs against that one weak spot in Jason’s pussy, constantly massaging into it and stimulating it. 

The pleasure is less intense but it builds much quicker. Jason feels his breath quicken, beginning to pant, his body starting to twitch in uncontrolled ways. More slick seeps out from beneath him and all across his thighs. His lips part in a keen and he can’t do anything but try and jerk away instinctively from the mounting sensation of pain and pleasure. Nightwing merely holds his hips down so he can’t escape. 

It’s too much. Jason comes with an overstimulated scream, eyes rolling up in his head as his vision goes white. He slumps against his lover, shaking through the aftershocks, mind completely blank from pleasure. He doesn’t even think he came that hard last night— the bedding is drenched from his release. 

Nightwing is still holding him. There’s a faint flush on his cheeks and a few beads of sweat, which Jason is quick to kiss away. When he pulls back, the vigilante’s expression has changed into one of contemplation. He looks like he’s deep in thought, nevermind the fact that he just made Jason come on his still throbbing shaft. As he stares off into the distance, a thin wrinkle middles his brows. 

“What’s wrong?” Jason asks. 

The frown on Nightwing deepens. As Jason watches, he seems to reach a conclusion, mouth opening to speak. “I… I miss…” 

“You don’t miss anything,” Jason says. 

Nightwing’s eyes turn to him in surprise. Jason wiggles off his cock, mourning the loss of it inside, all so he can cup the vigilante’s face close. Nightwing relaxes into the kiss, although there’s still a downward twist to his mouth. 

“But…”

“Hush, lover,” Jason shushes him gently. “What could you possibly want when I’m here?”

Maybe it’s the morning sun that is working against his favor, but Jason can see Nightwing start to shake off the effects of the hypnosis as he loses the last remnants of sleep. The bright-minded vigilante has always had a tolerance for their mind control spores, but clarity is returning to Nightwing at a much faster rate than even Ivy could have anticipated. 

His beautiful face darkens with realization. “Hemlock…” 

Jason quickly pushes Nightwing back onto the pillows, holding the other down with his inhuman strength. He wraps a hand around his stiff cock, ignoring the way Nightwing tries to buck out of his grip as the branches from their tree-bed ensnare his arms, and wraps the other hand around Nightwing’s mouth.

He blows a puff of pink dust into Nightwing’s nose and eyes. In a moment, the vigilante’s struggles die and he goes slack on the bed. A glassy look comes over Nightwing’s eyes as he falls back under the influence of the spores. 

When Jason pulls his hand back, Nightwing is smiling lovingly up at him again, irises glowing pink around the edges. Jason’s heart is beating rapidly in his chest, but he can’t help returning the smile of his lover now returned. 

“Bad boy,” he admonishes with a purr. “You’re a bad boy for trying to rebel.” 

Nightwing’s eyebrows raise and he looks around owlishly, taking in restraints on his wrists and ankles. “Oh. Sorry.”

“We’ll have to punish you later,” Jason says. Crisis averted, he begins to work his hand up and down the shaft, fingernails dragging against its underside. Nightwing arches into his touch with a pleased noise. 

Jason nibbles on Nightwing’s bottom lip as he continues jerking the man off. Under his control, Nightwing is all pliant and wanton, shamelessly moaning his pleasure into the air, letting Jason know exactly how good he’s making him feel. His legs are sprawled out beneath him, hair in a halo around his head as he just ruts into Jason’s hand with a blissed out expression. 

He’s nothing like the feared vigilante everyone else knows him as. Here in their canopy bed, Nightwing belongs only to Hemlock. He’s his precious consort that he can pamper and groom and fuck himself on whenever he wants. 

Ivy gave him such a good present for his birthday. 

When Nightwing comes in his hand, Jason doesn’t even blink before he licks it off. He savors the slightly bitter taste, before leaning down to suck the tip clean of cum while the vigilante quivers and gasps beneath him. Then he sits back up to press mouths against Nightwing, letting him see for himself how good they taste together. 

Nightwing moans, eyelids fluttering.

“Let’s get ready,” Jason says. “We have a big day.”

 


 

A few hours later, they leave the canopy of leaves and climb down to a small glade surrounded by trees, which is currently functioning as Hemlock’s open air living room. 

When he’s outside of Arkham, Jason likes to pick an unassuming spot in Robinson Park to make his home. He uses the trees here to shield it from visitors, always redirecting them away if they wander too close (and occasionally snapping them up for a little snack, if his plants are feeling peckish).

 Ivy has her own apartment in the city, but something about being in the park reminds Jason of the time he spent on the streets, before he was put in the foster care system. He’s always been more comfortable providing for himself. 

Still, his mentor makes a habit of dropping by to say hello. Her presence is indicated by the little bushel of hemlock sprouting in the middle of the room, which was definitely not there a few hours ago. Jason grins as he sees the small box sitting atop the white flowers, and the card with Ivy’s handwriting on it.

Enjoy your time together, my sapling. 

She spoils him. 

Nightwing is standing by as Jason unboxes his gift and pulls it out. It’s a gorgeous wreath made of green twine interwoven with strings of golden hay. A blue flower adorns the center of the wreath— a forget-me-not, which matches Nightwing’s eyes on a normal day. Jason takes the collar and turns to his consort, feeling little daisies open across his nape in badly concealed excitement. 

“Remember our anniversary?” 

Nightwing frowns. “We have an anniversary?” 

“More or less,” Jason lies, blatantly. He moves his hands up to start fastening the wreath around Nightwing’s bare neck. The vigilante lets him, still regarding him curiously. 

“The first time I captured you,” Jason explains. “The time with the venus flytraps?” 

Nightwing’s expression brightens, pink eyes alight. “Oh! Right.” 

They are talking about it lightly, but that time with the flytraps was one of Ivy and Jason’s first successful plots to take over Gotham. It was also the first time Hemlock and Nightwing really got down and dirty in their fight, where the unspoken sexual tension between them finally hit a breaking point. 

… Maybe that plan would’ve been successful if Jason hadn’t been so busy fucking Nightwing inside the flytrap he ensnared him with. Oh well.

He finishes fastening the collar and steps back to enjoy the view. Nightwing is a godly statue in the making, completely naked in the light except for the flower ring around his neck, and the mottled hickies all across his body. With golden tanned skin, he looks like he’s glowing. 

He still has his mask on however, because unfortunately after all of this, Jason is going to have to return him to where Ivy abducted him off the roofs, memories wiped of the last forty-eight hours. And if he wants Nightwing to ever speak to him again, he needs to at least leave his secret identity intact. 

Jason tugs him over to a fern bush acting as a table, and sits him down. They have berries for breakfast, although it’s mostly Jason hand-feeding Nightwing because he gets his own sustenance from water and sunlight. Nightwing takes every piece of fruit from his fingers so willingly but gently, like a bird, it makes whatever he has for a heart skip. 

There’s just something about watching him in this docile state, knowing that only Jason can see him this way, that Jason made him this way, which fills his chest with want. He wants to see more of this side of Nightwing, submissive and obedient, not mouthing off like he usually does (although Jason loves that part too, but everyone gets that part of Nightwing and so it’s nothing special.) He’ll cherish every moment that he gets. 

They finish up breakfast and Jason goes about tidying the living space while Nightwing just sits at the table and watches him. He knows they usually only get to see each other at night, but while Nightwing always looks dashing in that dark uniform of his, Jason must be underestimating how much better he himself looks in the day. With the fresh morning air and bright sunlight feeding his cells and leaves, making them bright and iridescent, he probably also looks heavenly, like a forest deity. 

He notices this when he bends over to check on some clovers and Nightwing makes a small keening sound. He looks over his shoulder to see the vigilante staring at his ass, overtly drooling. His dick is already starting to chub between his legs. 

Jason is hopelessly endeared. He straightens some ivy plants on the wall and then stands up. “Come here,” he calls. 

Nightwing gets up obediently. When he gets close enough, he wraps his arms around Jason’s midriff and tucks his face into the back of his neck, nuzzling the flowers there. Nightwing gets cuddly when he wants something, it’s so cute how much he’s just like a dog. 

He slides his hardening shaft between Jason’s legs and starts to rub it against them, letting out a small pleased sound. “Hemlock…”

Jason bites his lips as he feels himself beginning to slick up. Their libidos truly do match up. “Go on, lover,” he says breathlessly. “Just the thighs, yeah?” 

Nightwing seems happy where he is. He starts rutting against Jason’s ass, using his thick thighs as a cocksleeve. It’s unbearably hot to feel his stiff rod moving between Jason’s legs, first awkwardly and then smoothly once it gets covered in enough slick. Jason gasps as a few wild thrusts end up chafing against his hole, but Nightwing just goes back to grinding between his thighs again. 

“Tease,” he mutters. 

Nightwing’s hands start to wander up to the cup of his chest. He gets handsy immediately, fingers pinching and rubbing Jason’s nipples until they harden into little green buds. Jason bites back a small moan, content to tip his head back and let the touch-starved vigilante do what he wants.

They stay like that for a while, Nightwing fondling his pecs and rubbing against his thighs at a rate just quick enough for a lazy stimulation, but not so fast that he’s on the route to climaxing. 

It’s enough that Jason can close his eyes and enjoy the feeling altogether. That’s also when he hears something he missed earlier— a little birdsong happening right outside his abode.

Huh. 

Jason opens the petals of a trumpet flower at his entrance, speaking through it like an intercom. “What do you want, birdie?”

Robin’s chirrup-like tone answers him. The little bird sounds angry. “I know you have Nightwing, Hemlock!”

Still thrusting against him, Nightwing mouths hungrily at his nape. Jason tilts his head to give him more access. “I have no clue what you’re talking about.” 

“You totally do! People saw Poison Ivy kidnap him in broad daylight!” 

“Hmm. Red-haired plant lady with big thorny vines?”

“Yes!”

There’s a particularly hard nip on the throat, an insistent thrust between his legs, and Jason holds back a pleased moan. He can feel Nightwing’s ministrations getting bolder, maybe feeling a little jealous that Hemlock’s attention isn’t on him right now. His lover’s possessiveness makes him purr and he looks back briefly to mash lips with him, gasping at the way Nightwing’s tongue just dives down his throat. 

Jason loses track of time in their kiss as Nightwing ravages his mouth. He can be so assertive when he wants to be. Eventually he remembers who he’s speaking to, and has to push Nightwing gently away, lips still painted with his saliva. 

“Sorry, doesn’t ring a bell.” 

Hemlock!” Robin is agitated. “He’s been missing for two days!”

“Who is that?” Nightwing mutters dazedly. “Who are you speaking to?” 

“No one important,” Jason assures him. He presses back against Nightwing’s hips, squeezing his thighs together and coaxing a groan out of the man. “Why don’t you focus on fixing your little problem, ‘Wing?” 

Nightwing blinks at him, confusion coming over his pretty face. “But… I wanna make you feel good too, Hem. It’s your birthday.” 

Oh, Hemlock’s little plant heart can’t take it. He’s just as guilty as Ivy for spoiling his loved ones. 

“Okay,” he croons. 

He turns back to the intercom as Nightwing goes back to kissing and caressing him. He can tell from the bird’s twittering that he’s overheard practically everything that was just exchanged. Oops. 

“Well, you heard it.” Jason says, not bothering to hide the laugh that escapes him as Nightwing starts fondling his chest harder and pressing kisses down his spine. “It’s my special day, so I’m not letting him go any time soon. Nightwing is mine for the day.” 

Robin lets out an angry chitter. “I’m telling Batman!” Then he’s gone, grappled off, probably to make do on his promise and to tattle to Bats.

It does put a dampener on his mood that he’ll probably have to cut his day short with Nightwing. The moment the sun goes down, he can probably expect Batman to be marauding into Robinson Park, flamethrowers ablaze. And while he could spend time planning his defenses, or even just packing up his things and leaving, he doesn’t really feel like doing that on his birthday. Hemlock doesn’t really care if he gets sent to Arkham anyways. 

“You have such a controlling family, ‘Wing,” he grumbles, twisting around so he can wrap a leg around Nightwing’s waist and pull him closer. “Guess that explains why you are the way you are.” 

“Sorry, Hem,” is all he gets offered as Nightwing dips him gently onto a small ledge that just grew out of the wall. He lifts Hemlock’s thighs up in the air, sliding himself back between them. When he starts up again, his shaft rubs and grinds down against Jason’s clit. 

It takes only a few thrusts before Nightwing comes with a grunt, painting Jason’s abdomen and part of his chest white with his release. Jason comes a second later, mouth parted in a silent gasp and eyelashes fluttering as he squirts all over Nightwing’s front. 

It’s a filthy session, they’re both sopping wet from messing around for too long and need to go rinse off in the park’s fountain again, but Jason loves it anyways. 

 


 

Jason is just done trussing Nightwing up when the vines keeping his home protected part, and Ivy steps through. He grins down at her from where he’s hovering in the air, balancing on the apical bud of a grape vine as he adds the last finishing touches to Nightwing’s body.

“Pam!”

“Hemlock,” she says. “What are you doing to your caged bird now?” 

Jason hums as he strokes the vigilante’s heaving chest lovingly. “Punishing him. He got a little rebellious earlier.” 

Punishment is a light word for it, because Nightwing is clearly into whatever pretzel-like position Jason folded him into. He’s currently suspended in the air, twine binding his arms and legs behind his arched back like a roasted pig, with a delicate vinework crossing his chest and abs that Jason may have spent too much time on. His eyes are blindfolded with a few of the grape leaves. 

There’s a cute little daisy chain wrapping its way around his erect cock, the final flower perched pretty on top of his slit. Jason had just been preparing to sit himself on it when Ivy arrived. 

Going back to his mentor, Ivy barely bats an eye at the state she’s caught the two of them in. Of course, Jason has definitely walked in on her doing things with Harley Quinn on a routine enough basis that it doesn’t really bother him anymore. As the naked plant people of Gotham, they sort of are known for their promiscuity. 

He continues with his plan, seating himself on Nightwing. Nightwing lets out a little subdued moan, drools a bit, but he can’t do anything when he’s so tightly bound, not even thrust up into Jason. It’s the perfect little position to let Jason warm his cock while he picks up where he left off in his brand-new copy of Wuthering Heights.

Ivy watches him idly from below. “You realize that you could keep him forever, if you wanted to. We have already done research into how to affect long-term mind control.”

“Nah,” Jason says. “I don’t want Bats on my ass for the rest of my life.” 

“Speaking of, I passed him on my way here.”

“Did you guys fight?”

“I left him a small gift.” In Ivy words, that basically means that Batman will be here within the hour. 

Jason frowns and sets down his book. “Aw, really? We were just getting started.” 

Ivy shakes her head fondly. “You play with fire, sapling. You know Nightwing is Batman’s favorite pupil.” 

“Doesn’t treat him like he is,” Jason grumbles. He clenches down on Nightwing one last time before reluctantly getting off wincing a little bit at the chafing since he hadn’t much time to get wet. He hops onto the ground. “Then what are you here for, Pam? You didn’t have to come warn me, you know I’ll be fine going to Arkham for a few weeks.” 

"I’m interested in the research you’ve been doing,” Ivy replies. “The incubation of your child.” 

Jason brightens up. “Really? You’ve never been interested before!”

“You’ve achieved milestones I didn’t think you could. You’re a good scientist, Jason.” 

If anything, getting that praise is the next best present he’s gotten today. Jason thinks he’s beaming so hard that his skin is turning red from all the sugars coming to the surface. “Wow, that means a lot, thanks.” 

She gives him a light kiss on the cheek, before turning to leave. “Come along now.” 

Jason goes to follow before he remembers that he still has poor Nightwing trussed up in the middle of the clearing. He sidles up to his lover, caressing his cheek tenderly. Nightwing looks up at him with eyes that are still pink, but are slowly fading back to blue. 

“Where are you going?” he asks curiously. 

“We’re leaving before the Bat comes, ‘Wing. You’ll have to stay here.”

Nightwing’s expression turns to disappointment. “Don’t go, Hem. We’re having fun.”

“I know, lover.” The one fact that Jason can never get over is that while the spores do give him subliminal control over Nightwing, they work only to amplify what’s already there. So somewhere in that vigilante’s handsome head is a part of Nightwing that wants this, that wants to be strung up and treated like Hemlock’s treasured consort and property. Hemlock just doesn’t know how strong that part is. 

For all he knows, it could just be a fleeting fantasy of Nightwing’s that happened once and never again. But also, Nightwing did let Ivy kidnap him off the street, and he probably does know it’s Hemlock’s birthday. Maybe it is a more conscious thought after all. 

He presses a kiss to Nightwing’s lips, mouth lingering on the other’s. “We’ll have more fun, ‘Wing. I’ll see you again.” 

“Okay,” Nightwing breathes. Jason plucks the flower from his collar and wafts it quickly under his nose. He watches the vigilante’s eyes roll up into his head before Nightwing slumps down in his restraints, now unconscious. 

“You’re just going to leave him like that?” Ivy asks.

Jason shrugs. “It’s my birthday.”

 


 

They don’t end up getting very far before Batman catches up to them. Apparently, Ivy had kidnapped Nightwing on the eve he was supposed to set out for some Justice League mission, which meant that his disappearance was unfortunately broad-casted to heroes all across the country. 

A few of Nightwing’s friends show up to Gotham to help, and while Hemlock has tussled with the Amazon and the Atlantean on equal grounds in the past, they do the speedster with them this time, who he knows not to mess with unless he wants all of his plants run over. Jason makes the wise decision to give himself up so Ivy can slip away undetected.

Unsurprisingly, he gets a long berating over how evil and inhumane he is for abducting and brainwashing their friend. Then they get bored of rambling and toss him into Arkham so he’ll learn his lesson. Yeah right, like that’s going to happen. 

Arkham is where Hemlock is now, sitting against the wall of his cell and bored the hell out of his mind. He supposes the guards have learned their lesson from last time, where he used a dandelion seed that had drifted in from his open window to break out. Now they’ve stuck him in a dry musty cell with no sunlight, so that he’s forced to respire instead of photosynthesize to keep himself going.  

It sucks, frankly, compared to the sunny canopies of Robinson Park that he was just frolicking among. He wants Ivy to hurry up and come get him out. 

“Meal time, plant freak,” a guard yells through the cell’s door. Jason sighs. They give him half a glass of water and a raw steak on most stays, but apparently the asylum’s freezer broke down so now he just gets half a glass of water and a shotglass full of plant fertilizer. It isn’t even the right type of fertilizer for him, but whatever. 

The guard slides the tray through the feeding door. There’s the standard glass of water, but there’s a small shrink-wrapped muffin in place of the fertilizer. Jason picks it up like it’s a dead rat and looks at the ingredients. 

“I can’t eat this, dumbass. It’s plant-based.” 

“You’re Prisoner No. 243, aren’t you? This here’s your sponsored food for today. You eat it or starve.” The guard barks back. The door slams shut. 

Jason flips the door off, and settles back into his corner, ready to go back to daydreaming about his birthday date with Nightwing. Then his eyes fall back on the muffin and he frowns. 

There’s a little card tucked inside the wrapper. Jason unwraps the shrink packaging so he can read it. It’s written in a hand he doesn’t recognize and the words look a little rushed, like the person scribbled the note quickly before they could get caught. 

happy late birthday! hope you like lemon poppyseed

Jason looks back at the small yellow muffin with seeds sprinkled across its top. He smiles. 




Notes:

Dick, hearing that Hemlock broke out of Arkham: Oh no!! how could that happen??
Dick: I guess I'll have to go bring him in. I hope I don't get railed. Again.
Tim, who watched him sneak in the muffin: :/

 

I love to think that Nightwing does like the feeling of being owned by Hemlock, he just doesn't want to admit it <3 Thank you for reading!!
