Author's Notes: Revisiting Tim and Kara in a DCAU adjacent continuity.
Robin's bedside lamp cast an eerie glow on the young hero's face as he watched Supergirl sneak into his bedroom. She glanced around nervously before she finally closed the door and leaned against it, grinning like a Cheshire cat.
Robin grinned when he saw her. "Well if it isn't my favorite Kryptonian," he said, standing up from his bed and walking towards her. The hot blonde was a few years older than him and he was looking forward to taming her.
Supergirl's heart raced as she looked up at Robin. He was handsome, with his dark hair and piercing green eyes. Tim Drake wasn't Batman's first partner and she'd first met him as a cocky little kid with messy black hair. As he'd grown older, that attitude had started to grow more and more attractive and she'd found herself flirting with him more and more since he'd joined her on the Justice League.
"Hello, Robin," she purred, sashaying across the room towards him. Robin whistled in appreciation, his eyes dragging up her impressive body, admiring the way her half-shirt and mini-skirt showed it off. "I'm here like you asked," she smiled, trying to hide how nervous she was.
After all this time flirting, he'd called her out on it. Challenged her to come to his room tonight and he'd 'make her feel incredible.' It was a promise she couldn't resist. She'd been tempted to wear something fancy for him but decided to stick to her costume. It seemed to be doing the trick.
Robin raised an eyebrow, his lips quirking into a half smile. "Is that so?" She reached out, tracing a finger down his chest. "I couldn't resist your offer."
Robin's grin widened as he caught her hand, tugging her closer. "Knew it." He leaned in, pressing a kiss to her lips. She smiled. He was a good kisser.
Supergirl's eyes widened as he pulled away, reaching into his bedside table and pulling out a length of rope. She blinked, then started to laugh. "You're going to tie me up?"
Robin nodded, his eyes gleaming wickedly. "Oh, yes. I want to play a little game with you, Supergirl. I want to see just how far I can push you before you break."
She swallowed hard, her heart pounding in her chest. Said so confidently, his words sent a thrill down her spine. "Alright," she whispered, her voice shaking slightly.
He grinned, then grabbed her wrists, quickly tying them together with the rope. He pulled her arms above her head, securing them to the headboard of his bed. She tested the bonds, they were secure. He must know she could use her super strength to break free though.
Robin leaned in, his breath hot against her ear. He reached down, his fingers tracing a path down her thigh. "Spread your legs for me, Kara." She obeyed, her heart racing as she felt his fingers brush against the edge of her underwear. He chuckled, then reached into the bedside table again, pulling out a small, silver vibrator. She suddenly felt the strength of the knots around her wrists much more.
"This is a kryptonite vibrator," he explained, reaching under her skirt and pressing it against her underwear. She gasped, her hips bucking as the vibrations sent a jolt of pleasure through her body. "So no powers I'm afraid. But a lot of pleasure."
She whimpered, her body trembling as he teased her with the vibrator. He pressed it against her clit, then pulled it away, leaving her wanting more. She squirmed as he left the vibrator humming by her knickers as he gripped her skirt and forced it up her firm thighs until it was bunched around her waist like a strip.
She jumped as he slapped her thighs. The stinging sensation the slaps left was a new feeling for the young Kryptonian. He grinned as he eased down her panties, exposing her bare sex. Her cheeks blushed red as she watched him hold her panties up to his face, inhaling her scent, before stuffing them into his pocket.
The vibrator pressed against her again, as Tim used it to trace her folds. Then he circled her clit with it, mercilessly teasing her. Her hips bucked and spasmed. She gasped for breath when he pulled it away.
He grasped her ankles and, with a cheeky grin, pulled them up as high as they would go, lashing rope around them and tying them to the headboard too. With her legs spread wide and her ankles by her ears, Kara was totally vulnerable. As he proved with his next action.
He spanked her, his hand coming down hard on her ass. She cried out, her body jerking as the pain mingled with pleasure. The vibrator sat on the bed by them, the green crystal inside still making her powerless, helpless, vulnerable. He spanked her again, hard enough to leave a red mark.
Tim was just warming up. He delivered blow after blow to her ass-cheeks in turn. Each one harder than the last. There was a consistent rhythm to his strikes. She had about a couple of seconds between each one. Kara had tried to maintain some dignity at first. But she was crying out with each blow now.
Again and again, Robin's hand made contact with Kara's ass, the skin turning red; a beautiful contrast against her usually milky skin. Her gasps and moans filled the room.
"Beg for it, Supergirl," he growled, spanking her again. "Beg for your orgasm."
"Please," she whimpered, her voice barely audible. "Please, Robin. Let me cum."
He chuckled, then pressed the vibrator against her clit again, holding it there as she writhed and moaned. She was so close, so fucking close. But just as she felt the orgasm building, he pulled the vibrator away again, leaving her gasping and frustrated.
He spanked her again, then reached up, untying her ankles and letting her legs come down again. He ran his hands up and down her thighs a few times to tease her. Then he took her bunched up skirt from her midriff and dragged it down her legs and off her. He pressed his lips to her navel and let his tongue loose. She whined, writhing beneath him.
"You make lovely noises," he grinned, "but I need some piece and quiet to concentrate," Robin winked. Kara's wyes widened as he took her skirt and tied it around her jaw, gagging her with it. She made a muffled noise of protest and got a pinched cheek in mockery for her troubles.
Then gripped her top and yanked that up to expose her breasts. Her bra was quickly disposed off and she closed her eyes with pleasure as he groped and squeezed her tits.
After giving her breasts a few hard slaps and gleefully tweaking her nipples until they were red, Tim was ready. Kara could see it in his eyes.
He reached into his pants, pulling out his hard cock. He stroked it a few times, then positioned himself at her entrance. She moaned, her body trembling as she felt him push inside her.
He started to fuck her, his hips pistoning as he drove himself deeper and deeper inside her. She moaned, her body writhing as she felt the orgasm building again. She was so close, so fucking close. But just as she felt it cresting, he pulled out, leaving her gasping and frustrated.
He grinned, then reached down, pressing the kryptonite vibrator against her clit again. She moaned, her body trembling as the vibrations sent pleasure coursing through her veins. Then he pulled it back.
Her eyes widened as she felt the vibrator press at her tight asshole. She shook her head frantically. He shrugged. "I said I'd break you…" Then he pushed it forcefully into her ass.
Kara screamed into her gag. He playfully pumped the vibrator into her tight rear a few times before leaving it there. Her eyes were watering now. He grinned. He was loving this. He stroked his cock a few times then pressed it back into her pussy.
It didn't take long to finish fucking her now with this barrage of pleasure. He pounded into her relentlessly while vibrations shot through her from her rear. He grabbed her a fistful of her blonde hair at the top of her fringe and pulled, forcing her head up to look at him. He was grinning from ear to ear. Her scalp burned with pain.
The gag was muffling it effectively but she was screaming with pleasure as he fucked her. That scream only intensified as she finally orgasmed. He pulled back, thankfully sliding the vibrator out as he did, letting her thrash about in pleasure until she was finished.
Kara looked up at him with wide eyes. His hand was curled around his erection, pumping slowly. He came over her face, his hot cum splattering against her skin. Supergirl's eyes stung as she felt the warm cum hit her skin.
She blinked as there was a flash of light. He had his phone out to take a photo. He pulled the skirt from her mouth and she gasped in as much air as she could. Then she felt his cock slap against her cheek. She sighed and opened wide.
Her cheeks hollowed as she sucked him clean. He groaned with pleasure, feeling her lips pumping his shaft up and down, as she drew out his ejaculation as long as possible. She realised he was still holding up his phone. He was filming her do this.
He grinned as he slid out of the blonde's mouth and put his phone down at last. She lay there, panting for breath. "So was it as good as I promised?" He winked. "Mhm-hm," she moaned in agreement, smiling. It had been fucking incredible.
He reached out to her face, which was still stained with his cum, and rubbed her face possessively, rubbing his juices in and smearing them around. "Going to come back for more tomorrow?" He asked, holding out his fingers for her to suck clean. "Mhm-hm," she agreed again.
Robin untied her and helped her to her feet. He picked up her cape and playfully pulled it round her throat, pulling her back against his chest. "And what am I going to do to you tomorrow?" He whispered in her ear, pulling the cape a little tighter around her throat to ensure he got the right answer.
"Anything you want," she giggled. "That's my girl," he said proudly, releasing her. He spanked her sore, red ass one last time as he gathered what she could find of her clothes.
She stumbled out of his room, exhausted and embarrassed. But as she got back to her room, she felt her strength returning and she slept that night with a huge grin plastered across her face.
