The two criminals kissed passionately, as their tongues dueled against each other.

Isabelle out her arms around his neck as Ratigan's hands pulled her dress back, gripping her bare thighs. One of his hands started untying the back of her dress, undoing the hooks. He quickly did that and then undid the back of her corset. He then pushed it all down to her waist, showing him her bare chest and ample breast. He lifted her higher, sucking one of her breasts, grazing the nipple with his sharp teeth.

Isabelle moaned as she pressed his head closer to her chest, feeling his long tongue lick her breasts. She breathed harder as she tried to move his jacket down and take off his cravat. She didn't realize that as she tried to pull it off, it was going tighter around his neck. He growled as he release her with one hand and ripped his cravat along with his jacket. He then saw her breathing heavily, her chest nearly heaving.

"P-Padriac, I n-need you...please!"

Ratigan looked at her panting. He wanted her just a bad, so he undid his zipper, letting his hard-on out. He then lifted her a bit, removing her underwear. He groaned slightly when he felt just how wet she was, she was actually dripping down her thighs.

Taking a deep breath, he put the tip in her, both rodents hitching from the intense feeling. Ratigan then put more of himself in her, his eyes shut tightly as he grind his teeth, as he felt wrapped in her tight heat. He then heard Isabelle whimper, making him open his eyes and seeing her face scrunched in pain and tears in her eyes. He was about to ask what was wrong when he realized just how tight she was.

Oh shit.

Isabelle hasn't slept with anyone since that preacher's kid when she was 14; she was unbelievably tight.

"Isabelle." he whispered, seeing he look at him with tear-filled eyes. "Do you want me to-"

He didn't finish his sentence when she smashed his lips to his, shaking her head. He understood as he slowly thrust into her, stopping whenever she gasped in pain. By the third thrust, she started to moan as he started panting.

Isabelle then gave a loud moan, when Ratigan suddenly covered her mouth.

"Isabelle, we're hiding. We have to be quiet." eh whispered, even though he was having problems being quiet as well. Isabelle nodded as she bit her lip, trying to keep her moans in. Ratigan grunted and growled as he continued to thrust into her.

Ratigan then remembers what Neil said, about being with Isabelle was like playing with fire. He understands as he thrust into her; he felt like every fiber in his being was burning. My God, he felt like he was being burned alive.

Isabelle was trying hard not to scream as she bit Ratigan's shoulder, eyes clenched shut. She felt so full, yet she loved every minute of it. She kept whispering his name over and over, feeling him grip her thighs harder as she said it.

She heard him whisper many things to her, saying "Darling" and "Isabelle" in a raspy tone. One of the things he said that got her a little confused was him saying, "My Valkyrie". She tried to understand what he meant, but the other sensations she was feeling made it fly from her mind.

She opened her eyes and saw that his large tail was thrashing widely. She then pulled back to look at his face, which was just as flushed as her, while they stared at each other with passion in their eyes.

"P-Padriac..." she whispered, "I-I'm close."

Ratigan nodded and said, "So...am I."

As he thrust harder into her, both breathing heavily as they felt their orgasms approaching, Isabelle suddenly hugged herself tighter around him and smashed her lips to Ratigan's, screaming in his mouth as an orgasm ripped through her. Ratigan felt her tighten around her and with a loud groan/growl, he poured into her.

His legs suddenly felt weak as they slid to the floor, still clutching each other. Ratigan removed his hands from her thighs, noticing that they are now dark bruises on them. Isabelle seemed to catch her breath as she smiled and gave him a quick kiss on his lips. He smiled roguishly as he kissed her back. Suddenly, Isabelle pulled away, leaving him confused.

"Padriac...what time is it?" she asked Ratigan went into his vest pocket (which he wondered why it wasn't ripped off) and took out his pocket watch.

"Its five to midnight." he said, then his eyes widened with realization.

Abigail was supposed to let them out at midnight.

They quickly got up and tried to hurriedly fix themselves up. Ratigan zipped up his pants, put on his jacket (which he realized distastefully was wrinkled) and tie up his cravat.

Isabelle pulled her corset and gown up. She tried to reach the back of it to tie them, but Ratigan moved her hands away as he tied it and button up her gown. Apparently, it was just on time, because they heard a knock on the door and Abigail's voice.

"Isabelle, Professor, are you in there?"

"Yes, we are, Abby." Isabelle said as Abigail (who was wearing a maids outfits) opened the door, the youngest Cassidy noticing that they both looked tense as they left he room. She then shook her head and went to business.

"OK, you suite is on the 4rd floor, third door to the right. Professor, you room is right next to hers." she said, giving them their keys, and then looking at the two suspiciously.

"Are you two alright?" she said, watching them blink and nod frantically.

"Yeah, we're fine. Thanks, Abby!" Isabelle said frantically, and then leaving quickly to her suite, with Ratigan following suit. He noticed that Isabelle was walking oddly, then he realized that she was actually limping. He grimaced; he didn't mean to be so rough with her.

Isabelle then stopped in front of her suite, turning to look at her rat lover. When she looked up at his face, she blushed darkly and averted her eyes, making him chuckle. He tilted her chin to look up at him, dual colored eyes meeting smoldering yellow.

"I must ask, my dear...was I...a boring lover?"

Isabelle looked at him with disbelief, wondering why he would ask her that. That's when she remembered when she told him of her first time, how boring it was. She blushed darkly and shook her head.

"No, you weren't. You were a bona fide good lover." she said, making him laugh loudly. He then gave her a quick kiss on the lips, then started walking to his own room. He then looked back at her with a secret smile.

"I can assure you my dear, next time, it will be much better than the last."

The statement made Isabelle blush even more, wondering just how much better the next time they make love will be.

AN: FINALLY! A SMUT CHAPTER! I BEEN WANTING TO WRITE THIS SINCE CHAPTER 1!

Yeah, they do it in a closet while on a job, not a smart idea and its a miracle that nobody heard them.

Yeah, I don't think Isabelle with sleep with anyone since that kid when she was 14 back at Clearwater because she wants to share it with someone she equally wants. That's why she was really tight.

Remember what Neil said to Ratigan at the end of chapter 17, Twilight Chapter 2? About being with Isabelle is like being with fire and that she's a Valkyrie? Ratigan is thinking that while he's making love to her, it just sounds good.

So, Abby let them out, they got to their rooms and Isabelle tells Ratigan that he wasn't boring at all. I just had to make her say something southern like "bona fide". Lol, she sounds cute saying it.

Anyway, I hope you enjoyed this chapter, next one is the heist. So stay tuned and comments are loved!

I don't own GMD, just Isabelle and Abigail!
