Author's Notes: Feel like I need to specify this is not intended to be Young Justice. I've looked to the comics Titans run by Dan Abnett for M'gann's characterisation here. Enjoy
M'Gann's green skin flushed as she argued with Nightwing, her red hair swishing around her as she pointed her finger at him.
"Batman trusts me to handle things, Nightwing. I don't need you to tell me what to do."
Nightwing sighed, running a hand through his dark hair. "Look, M'Gann. I get that you're used to following Batman's orders, but this is my team. I'm in charge here, not you. And I won't tolerate insubordination."
M'Gann crossed her arms over her chest, her full breasts pressing against the fabric of her costume. "Fine. But I still think I should be reporting directly to him."
Nightwing shook his head. "I don't have time for this. Follow me."
He turned and stalked off, leaving M'Gann no choice but to follow him. She gritted her teeth, annoyed at being treated like a child. But as she followed Nightwing down the hallway, she couldn't help but admire the way his ass looked in his tight costume.
Nightwing led her to his room, pushing open the door and gesturing for her to enter. M'Gann hesitated for a moment, but then stepped inside.
The room was dimly lit, with a large bed in the center. Nightwing closed the door behind them, turning to face M'Gann.
"Listen, M'Gann. I don't want to fight with you. But you will learn to follow my lead."
M'Gann's eyes narrowed. "Fine. I understand. But what does this have to do with anything?"
Nightwing stepped closer to her, his eyes blazing. "This has everything to do with it. I need to make sure you understand who's in charge. And I need to make sure you're willing to follow my orders."
M'Gann's heart started to race as Nightwing reached out and grabbed her, pulling her close. She could feel his hard cock pressing against her, and she couldn't help but respond to his touch.
Nightwing's lips crashed down on hers, his tongue demanding entry. M'Gann moaned, opening her mouth to let him in. She could feel his hands roaming over her body, touching her in all the right places. His fingertips were like fire against her smooth, green skin.
Nightwing broke the kiss, pulling back to look at her. "Do you understand now, M'Gann? Do you understand who's in charge?"
M'Gann nodded, her breath coming in short gasps. "Yes. I understand."
Nightwing smiled, his eyes dark with desire. "Good. Then let's see how obedient you can be."
He reached down, grabbing the hem of her shirt and lifting it up over her head, taking her cape with it. Then he reached down and loosened her skirt, letting it fall to her ankles. M'Gann stepped out of it, standing before him in just her bra and panties.
Nightwing's eyes raked over her gorgeous green body, taking in every inch of her. M'Gann could feel her nipples hardening under his gaze, and she knew he could see how wet she was through her panties.
Nightwing reached out, tracing a finger over the curve of her breast. M'Gann shivered, her pussy clenching with desire.
Silently, he reached behind her, unhooking her bra and letting it fall to the floor. M'Gann's breasts spilled out, her nipples hard.
Nightwing reached out, cupping her breasts and squeezing gently. M'Gann moaned, her pussy getting wetter by the second.
He leaned down, taking her nipple into his mouth and sucking gently. M'Gann cried out, her hands reaching out to grip his shoulders. He smirked.
Nightwing moved his mouth to her other breast, teasing her nipple with his teeth. M'Gann's legs started to shake, her pussy throbbing with need. She definitely knew who was in charge now. "Dick," she moaned out softly.
Nightwing reached down, hooking his fingers into the waistband of M'Gann's panties and pulling them down slowly. M'Gann swallowed nervously, completely naked now.
Nightwing's eyes blazed as he took in the sight of her. He smiled, his voice softer than before: "you're beautiful." He ran the back of his hand gently down her lime-green body, soothing her silk-like skin.
"Guess it's my turn," he winked as he took off his domino mask. She watched, transfixed as he shed his black and blue costume. He grinned, stripped down to his boxers and sat on the edge of the bed, leaning back on his palms cockily. "Want to help me with these?" He asked with a knowing smirk.
M'gann nodded and dropped to her knees in front of him. She tugged his boxers down and tossed them over her shoulder. His cock stood to attention in front of her. He was even bigger than she'd expected.
She felt him thread his hands into her dark red hair, tangling his fingers in the crimson locks and tugging slightly to assert control. She opened her lips and leant forwards. He groaned as her mouth slid slowly down his shaft. "Fuck," he breathed out gently.
M'Gann felt a swell of satisfaction at his response. She kept her lips locked on his cock as she bobbed her head up and down slowly. He couldn't repress his groans of pleasure. She sucked diligently, savouring his taste.
He gripped her hair tighter as she swirled the tip around her mouth with her tongue. Her hands rested on his bare thighs, rubbing gently. He let himself lay back, releasing his grasp of her red locks to lie splayed on the bed, content to let her pleasure him as long as she wished to.
M'gann made the most of the opportunity. She wasn't sure how long she'd been giving this blowjob for by now but she was impressed with his resilience. The salty taste of pre-cum stung on her tongue but he seemed to refuse to break for her.
As M'gann came up for air, suddenly he grasped her shoulders, pulling her up towards him. Her body pressed against his on the bed. He reached up and stroked her cheek gently. "That was great," Nightwing whispered, "but I'm ready for the main course now…"
He rolled over so he was on top of her now. His hands entwined with hers, stretching her arms out to the sides. Her chest rose and fell with every breath. Nightwing grinned, positioning himself at her entrance. The young Martian girl but her bottom lip hard to stop herself crying out as he drove down into her. His hips started to rock back and forth and M'gann found herself whimpering.
His hands released hers to fly to her heaving chest. She moaned as he grasped her tits and squeezed harshly. Her arms wrapped around him, scratching at his shoulder blades.
Nightwing's fingers started to dance around her breasts. M'gann felt a jolt of electricity run through her as he pinched her nipples. She moaned, her pussy clenching down around his dick. Nightwing chuckled, leaning down to whisper in her ear. "You like that, don't you?" He nipped at her ear, causing her to whine.
The Titan's dick twitched inside her, causing her to gasp. M'gann raised her hips to meet his thrusts, making Nightwing growl. His fingers left her breasts to reach down and tangle themselves in her hair. "God, M'gann…" He mumbled, pulling her head back so he could kiss her.
M'gann moaned, kissing him back. Her fingers dug into his back desperatelyand she felt him smile against her lips. He broke the kiss and pulled out of her. M'gann groaned, missing him already. Nightwing smirked and rolled over so she was straddling him.
"Now…" He said, voice full of lust, "It's your turn to do some of the work…"
M'gann smirked and reached down to grip his cock. She positioned it at her entrance and slowly lowered herself down onto him. She felt herself stretch around him, making her whimper. Nightwing's eyes darkened as he watched her.
"Ride me, M'gann…" He ordered.
She started to move her hips back and forth. Nightwing growled, his fingers digging into her hips. She increased her pace, the sound of her skin slapping against his filling the room. Dick reached down to rub her clit, causing her to cry out.
Nightwing's hand shot up to cover her mouth. M'gann's eyes widened as she looked down at him. He smirked and leaned up to whisper in her ear. "They can hear you all the way in Gotham…"
M'gann moaned, trying to muffle herself. Nightwing's hand left her mouth and moved to tangle in her hair again. She whimpered as he pulled her down for a kiss. His tongue forced it's way into her mouth and M'gann moaned.
She started to grind her hips down against his. Nightwing's hands moved from her hair to her breasts. He pinched her nipples again, causing her to cry out into his mouth. He broke the kiss and started to thrust up into her.
M'gann threw her head back, moaning. Nightwing's hands moved from her breasts to her hips. He pulled her down to meet his thrusts. The bed creaked as they moved together.
"Fuck, M'gann…" Nightwing muttered, "You're so tight…"
M'gann moaned, her pussy clenching around him. Nightwing's thrusts became more frantic. M'gann could feel herself getting close. She started to rock her hips faster and faster. Nightwing growled, pulling her down for another kiss.
M'gann moaned into his mouth, her pussy clenching around him. She felt herself start to fall over the edge. Nightwing's thrusts became erratic and she felt him shudder.
"M'gann…" He cried, his fingers digging into her hips.
M'gann moaned, feeling herself cum. Nightwing collapsed back onto the bed, pulling M'gann with him. She smiled and leaned down to kiss him. His hands came down to rest on her back, stroking her soft flesh absentmindedly.
"That was the most incredible sex of my life," M'Gann breathed out. Dick chuckled. "That was the idea," he grinned. "You want it to happen again sometime? Then you follow my orders from now on. Got it?" M'gann nodded with a wide grin. She'd definitely got it.
