Hellboy sat on the gym floor as he held a book in his hands and his head tilted backwards on the wall as he listened to the sounds of wings whipping and fluttering through the air. He had his eyes closed as he absorbed the sounds of his love practicing with her wings.

His love.

It sounded so strange to say that to himself. He let out a soft sigh of content as he thought about the past week. After that night when they finally acted on their desire, they spent every waking moment they could together. It was almost as if it opened something inside them. He thought about the few times when he'd come back from a late-night mission with the knowledge that someone soft lied in his bed waiting for him. It had been so long since he had that feeling. When Liz was alive.

He'd come in silently, head to the bathroom for a quick shower, then slip into bed naked. And almost every time Angel would awake and drop her arms over him, giving him a warmth he'd missed. She'd sling a leg over his and his shaft would find it's home inside her, slipping in so easily. And she'd moan by his ear. He loved hearing her moan.

It wouldn't be long before he'd have to pull out, but it was worth it. Every time she'd shudder besides, above, or under him, he would memorize it all. The way her expression contorted into pleasure, her eyes shining as she looked at him, the way she gripped his bicep. He always regretted letting her go so he could clean up.

His member hardened beneath his cargo pants, and he opened his eyes to look down. He could see the slight tent his pants made. He heard a door open. He quickly dropped the book he held on top of his bulge, hiding it. He nearly groaned at the impact. He turned his head to see a male agent had entered the gym, staring upwards towards Angel.

"The gym is reserved," Hellboy growled. He didn't like the way he was looking at Angel.

The agent's head snapped towards the red demon. A look of surprise marred his face then he schooled it as he spoke, "Apologies sir. I didn't realize it was reserved. I'll come back after."

Hellboy nodded, glad he got his message across. He looked away, intending to continue to read his book to distract himself from his soon to be raging dick. But when the sound of the door didn't occur, he looked back. The agent was still standing there, holding onto his gym bag over his shoulder. He was looking up at Angel with an expression that Hellboy couldn't decipher.

He looked up at Angel. They had come here daily for a few hours so she could properly stretch her wings to their full length. After being cooped in her back for those many years, it certainly needed it. And it gave her opportunities to practice flying. He couldn't fault the agent for staring. She was beautiful.

But at the same time, he glowered. He should be the only one who gets to see her this way. She was vulnerable. He even knew Angel wasn't comfortable yet to let others see her.

"Agent," Hellboy growled when he looked back.

The man jumped, jarred out of his thoughts. He looked to Hellboy, and his cheeks reddened in embarrassment. "Oh. Sorry Sir. I couldn't…uh. Sorry." The agent turned around and headed to the door as Hellboy watched to ensure he did leave.

But at the last second the agent stopped then looked at Hellboy.

"Wouldn't she feel better if she was able to fly outside?"

Hellboy raised his eyebrows at the question. Of course, he had thought about that once or twice. But he had valued her safety above all, plus there wasn't really a place where she could do that.

The agent continued, "I don't mean to step over the boundaries, but we do have a roof, don't we? Wouldn't she be more comfortable up there instead of this space? The gyms too cooped up for someone like her."

The agent left before Hellboy could snap out a reply. He looked up. Angel swooped. The agent was right. They did have a roof. He never thought about that. They would still be on Bureau property…maybe that was an idea. He watched as Angel made her descent to the floor, her soft footfalls echoing as the wings folded in and disappeared.

He tossed the book aside as Angel walked towards him. Her eyes dropped when she got nearer, and she gave a smirk. Before he knew it, she kneeled over him. Her hands on his shoulders for support. Her legs on either side of him. She dropped her body down. The warm core of her over his hard heat. He wrapped his hands around her back, feeling the ridges of where her wings were housed.

"What was that?"

Hellboy shook his head, "Just an agent. He didn't know I reserved the place for you."

"Tsk. You should put a sign over the door."

He grinned. That's not a bad idea. He looked at the clock on the wall. "We've got like twenty minutes left." He looked at her, "We've got the whole place to ourselves. What do you want to do?"

She grinned salaciously. Her eyes twinkled. She took a hand and let it slide down his chest. "I think I have an idea."

Good Lord. What has he done?

He raised an eyebrow. He hardened. She leaned forward and pressed her lips against his. She wiggled her hips and he let out a groan.

"I think," He said as he pulled his head back to look at her, "you're a bit addicted."

She laughed, "Oh yeah. To you."

He pulled her against him, hard. They kissed and his tail wrapped itself around her ankle. He slipped a hand under her shirt, needing to feel her smooth skin. She let out a soft gasp at his cold fingertips. She pulled back and as she stared into his eyes, her hand went down further. Her fingers touched his belt and undid it.

He leaned his head forward and pressed his lips against her throat. "There's cameras around here," he murmured against her skin.

She pulled at his pants and the button snapped off. Then she spoke as she pulled the zipper down. "Has that ever stopped you before?"

He paused then leaned back. He looked at her. Watched her. She flicked open the slit of his boxers and slipped her hand in. Her eyes glittered with desire as she wrapped her fingers around his engorgement.

"No," he said as he shook his head.

Fuck no.

His tail unwound from her ankle and tickled her up her thigh. She pulled him out from his pants. She looked down. Pre-cum leaked from his slit and she swiped it with her thumb. Then she lifted her thumb into her mouth. His eyes darkened so quickly, and his hands moved before he could think.

She wore leggings. His stoned hand grasped the lining of her leggings and pulled, tearing the thin fabric away. She gasped in surprise. Then her lace underwear came next. She was pulled up into the air, her bottom lifting from his legs. Before she knew it, he slipped inside her all the way to the hilt in one slide. Her eyes widened.

He stretched her so differently in this position. She held onto his shoulders as he thrusted into her. There wasn't much she could do as he clamped his teeth on her shoulders where her neck met as he continued to thrust hard. She let out a gasping moan as her clit rubbed against the fabric of his boxers.

"Hel-" She could only gasp as pleasure rose so quickly; she couldn't control it. She let out a cry as she felt him rub against her walls so harshly.

He held onto her as her head fell back, her mouth opened in ecstasy. The sight of her like that above him, under his control nearly tipped him over. He pulled him to her hard as she shuddered, coming down from her high. He twisted her to the floor, so he'd hovered over her, never once slipping out.

He thrusted hard, breathing harshly by her hear. She grunted from the movement, and he pulled out. His member pulsed outside of her, spilling his seed on the floor. He closed his eyes against the desire and pleasure that had raged through his bloodstream. He opened his eyes, seeing her stare at him. Her hand palmed his cheek, stroking it.

He grinned at her and nipped at her bottom lip.

"I'm addicted to you too."
