Author's Notes: It's been a little while since the last update but the final chapter is up now! I realised that, considering he's my favourite Robin, I hadn't been treating Timmy Drake particularly well, so I figured I'd give him a super-experience. So it's Kara and Tim (and a bit of Steph) for the grand finale. Reign of Superman will be up soon. For what happened with Steph and Damian check out my Steph and Damian smut (the second story I ever uploaded, it doesn't have a fancy name: it's just Robin and Batgirl: Steph and Damian, or something like that)

Final Note: Tim here is based on mainstream Tim Drake, not the new 52 garbage heap they call Teen Titans. (I quite like most of the New 52, it's really just Teen Titans that I want to burn)

The door blasted open and Red Robin strode into the warehouse, confidence filling his stride and no expression tainting his face. Kara smirked, admiring his perfect features. "Where's Batgirl?" he demanded, without raising his voice. She giggled, "Steph's fine, in fact she's quite enjoying herself." Tim scowled.

Kara was lying on a large mattress, half-naked. It was clear what she was expecting. Tim could feel the purple kryptonite's effects growing on him. He knew he couldn't resist her for long. He'd barely been able to resist her before the change. The deal-maker for him though, was that his ex-girlfriend, Steph Brown, currently dating his nemesis, Damian Wayne, was tied up in the corner, also half-naked. Tim had to admit, this did improve Kara's chances.

He swallowed before he spoke: "Come in now and we can avoid any conflict here. We can help you." "I bet you'll cum first..." Kara whispered alluringly. Tim shook his head in disbelief. He sighed, what was the point? He'd have to go with Batman's plan after all. He was armed with the same neutralising agent that Black Canary was used on Superman. If he had sex with her, she could be brought in and imprisoned like Superman. Tim nodded, making up his mind. "Challenge accepted..." he muttered.

Kara grinned as he stepped onto the mattress, peeling off his shirt. Her victory in the argument had never been in doubt. She remembered when she'd first met him, back when he'd been Robin. He'd been a little shorter and a lot less broody. He'd made jokes and showed off, doing acrobatics. Now the closest he got to the boy she'd met was sarcastic comments and the occasional moment during combat. Tim Drake had grown up since he'd become Red Robin. She found that made him even sexier, and he was pretty sexy to start with.

"Want me to let Stephanie go first?" she purred as he climbed over her, his arms wrapping around her shoulders. "Let her watch..." he muttered with a slight glint in his eye. She licked her lips then reached up and kissed him. Her legs lifted and gripped his waist. His lips parted to let her tongue enter while his hands ran down her back and unhooked her bra.

It fell away and he gripped her breasts, gently groping them. She moaned into the kiss and tugged at his belt until it came off. He kissed down her neck and she felt his dark hair tickle her skin as his lips pressed against her shoulder-blades. She ripped off his costume, his crotch bulging in his boxers. Both of the youngsters were breathing heavily as they reached for each other's underwear. His fingers dragged over her ass before sliding off her knickers while she simply yanked off his boxers in one fluent movement.

Her nimble hands gripped his penis, rubbing softly. He groaned and gripped her hips, raising them towards his. She obliged and released his cock, resting her hands on his back and pulling herself up into his embrace. His penis slid into her pussy and both closed their eyes. Kara thought she heard some faint mumbling from Steph in the corner, it sounded aroused more than irritated. Kara raised a finger to her lip to indicate the bound girl should be silent.

Kara knew that Batman would have prepared his partner for this. Tim was no doubt neutralising her through intercourse at that exact moment. She didn't care. She had waited too long for Drake already, and besides: it wouldn't matter providing Bane completed his assignment...

Tim started to move, thrusting slowly into her and Kara kept herself close to him. He grinded his hips down into hers roughly but it wasn't enough for Kara. She grabbed his ass and took control, making him thrust faster and harder. Tim grunted but offered no resistance, screwing her hard.

Suddenly she pushed him off and he rolled aside; she straddled his waist. Tim was breathing heavily as she encircled his nipples seductively with her thumbs. She cocked her head to the side and her eyes started to glow red, heating up. Tim felt his skin grow warmer from his close proximity as the lasers emitted from her eyes and fired across the room, striking the rope holding Steph.

Free from her bonds, Steph stood up slowly, rubbing her wrists. Kara released one of Tim's nipples to silently beckon Steph over to them. Steph did as she was told. Kara grabbed Steph's wrist and pulled her onto the bed, literally tearing away the slightly younger girl's bra. "Let's make a Steph sandwich..." Kara whispered with a naughty look filling her eyes.

Kara pushed Steph onto Tim, his cock pressing against the Batgirl's ass. Then Kara climbed onto her. Tim hooked his fingers under the fabric of her underwear and pulled it away. His dick slid into Stephanie's ass. Kara let him get started, thrusting forcefully up into her butt while Supergirl simply watched.

This moment brought back so many memories for Timothy. The smell of her hair, the feel of her skin, it was just how he remembered it. Could he still have feelings for Steph? It certainly felt like it. As his dick pounded her ass, his eyes glazed over, lost in the past. They hadn't left on the best of terms, and then she'd ended up with Damian, somehow. After the Superman incident though, he wasn't sure what her status quo was, particularly with Damian; he hadn't seen them together recently, not that he was looking.

Suddenly Steph moaned out and Tim snapped back to reality, seeing what Kara was doing. Kara had started to pump two fingers into Stephanie's vagina. With the other hand, Kara stroked Steph's cheek calmingly then yanked her head back by her hair. Steph moaned out again and Tim's penis pushed into her harder.

Tim took control and rolled over so now he was on top and Kara on the bottom, with Steph still stuck in the middle. He pounded down into her ass continuously, impaling her on Kara's awaiting fingers. Steph couldn't stop the string of moans and cries escaping her.

Steph was so confused. Kara was her best friend, but here they were, screwing like dogs. She had seen Oracle's data back in the original crisis, it hadn't said anything about it affecting the same sex, what did that say about her and Kara? Was this more than just the kryptonite?

And then there was Tim Drake. Her first real boyfriend, she'd thought she loved him. No, she knew she'd loved him. Then they'd broken up and within a couple of years she'd ended up with Damian. The truth was though, she'd never lost those feelings for Tim. Now here he was, fucking her harder than Damian had even dreamed of, what was Kara doing to him? What had she done to him herself? Ever since their breakup and him becoming Red Robin, he'd been different, darker, broken...

The joint stimuli of Tim's thrusting and Kara's fingering caused Steph to explode, giving into orgasm. Kara grinned. "Can you do that to me as well Boy Wonder?" Kara wondered out loud, ignoring Steph now. Kara pushed Steph aside and straddled Tim's waist. He smirked and nodded: "Easily..."

Kara dropped her hips into his, his penis sliding back into her vagina. He pushed onto her back and slammed down forcefully. Kara moaned as he fucked her, just as hard as he had fucked Steph. It wasn't the hardest she'd been screwed, but he had no superpower, so his commitment and endurance were astonishing. Her eyes rolled into the back of her head. He smacked her ass and pushed his lips to hers. His cock pounded her pussy relentlessly and Kara and she called out. How did he have this much power over her?

Then she saw it. Pressed into the palm of his hand, which was resting on her shoulder, was a tiny shard of green kryptonite. Not enough to hurt her, but enough to make her feel the way he was screwing her, like a normal woman would. He must have got it out of his utility belt while Kara was getting Steph for them to play with.

Kara moaned out again as he hit her g-spot. She couldn't take it anymore. As he crashed into her for the last time, she erupted. She moaned as she orgasmed. Tim smirked again then moaned out also as he came with her. He kept inside her as he came, he had to for Batman's plan to work. He glanced over at Steph who was lying on her back with her eyes closed, breathing heavily. He swallowed then pulled out.

Kara ran her hands down his torso, breathing heavily, "You're fantastic..." she muttered, "Steph is a lucky girl..." Tim shook his head, "We're not..." she stopped him mid-sentence. "I guess I'm going to sleep in a minute, with the neutraliser you used," he raised an eyebrow, as she revealed she knew, "so stop lying to yourself..." With that, Kara's eyes clicked shut...

When Kara awoke she was in a cell almost identical to the one Superman occupied. She smirked. "I'm coming..."
