Somnophilia / Hate Sex

He pisses her off and then turns her on. Trouble is he's good at both.

"Alvez, will you be so kind as to shut your trap!" Penelope barked from her spot in front of the computer. Rossi had managed to do something to the machine and it was currently sitting lifeless on his desk - Penelope just had to figure out exactly what he had done.

"I'm giving you good advice!"

"Telling me to turn it off and back on again is pretty ridiculous seeing as I can't even get it to turn on!" she practically growled.

"And you call yourself a computer genius?" He shook his head and tutted.

Penelope clenched her fists together and then released, exhaling a calming breath as she did so.

She decided it would just be best to ignore him so she stood from the chair and leaned over the desk, turning the tower of the computer around so she could see if there was an issue with the cables.

"I don't know why people go on about you - you can't even turn a computer on."

She knew he was goading her. She knew she should just ignore him. But she couldn't. It wasn't possible.

She turned to face him with fire in her eyes. "If you don't be quiet within the next three seconds I will ram this computer where the sun doesn't shine - so shut up!" Her teeth were clenched painfully together and she was almost certain her eyes were bulging.

Luke held his hands up in defeat. "Fine - I'll leave you to it." He turned slowly and began to leave the room. Just before he got to the door he turned back around. "You have made sure the sockets on haven't you?"

He was grinning from ear to ear. She felt her entire face turn red as her eyes widened and her mouth opened.

Luke chuckled and closed the door quickly, leaving her alone as her feral scream of annoyance died in her throat.

She breathed heavily for a few seconds and then turned her attention back to the computer.

He was such an asshole.

Later that night when Penelope entered her apartment, she found Luke sat on the sofa watching some television. She'd had to stay behind and get Rossi's computer set up for tomorrow.

"Take your pants off," she commanded, throwing her bag to the floor and removing her jacket.

Luke stared at her for two seconds before grinning and doing exactly as she said. He stood up and in records time he was sat back on the couch, completely naked. He was already hard.

Penelope took her time in kicking her shoes off and then taking her dress, tights, bra and underwear off. It was a punishment. Luke could look but not touch.

When she was naked, she unpinned her hair from the up-do she had it in and let her blonde locks fall down her body, the ends tickling her bare chest. Luke's eyes darkened - he loved it when she had her hair down.

"You pissed me off today," she told him, straddling his lap and easing herself onto his body. His hands went to her hips instinctively and he squeezed.

"I know." He was cocky - literally.

"I didn't appreciate it." She rubbed the head of his cock all over her soaked flesh.

"It turned you on," he countered. "You're soaking."

He knew how she felt about them fighting. She loved it. They weren't dating per se, but he did spend a lot of time in her bed, on her couch and in her shower.

"You pissed me off." She reiterated the words from earlier.

"I turned you on," he countered, pressing his hips against hers, tempting her.

"Shut up," she growled, surging onto him.

He filled her completely as she cried out, her eyes closing instinctively and her hands moving to rest on his pecs, her fingernails scratching at the skin.

Luke placed one hand on the back of her neck and pulled her forward, eagerly pressing his lips to hers as he gently thrust upwards. Nothing too invasive, just small teasing strokes to get her going.

The movement made her moan but she wanted more. Penelope jarred her hips faster, rubbing every inch of her inside walls with the bulbous head of his cock.

It drove them both wild.

When she needed to breathe, Penelope pulled back from Luke and rested her hands behind her on his thighs, fingernails digging in once more. Her hips moved erratically and she threw her head back, feeling everything.

Luke leaned forward, pushing himself deeper as he captured a sweet nipple in his mouth and sucked on the hardened bud, his tongue swirling around the peak before he lightly bit down, pushing her closer to her impending orgasm.

He wrapped an arm around her waist and pulled her closer, neither of their hips keeping to the same beat. It all added to the pleasure.

"Oh…" Penelope sighed when she felt the familiar tingle in her lower belly and her clit began to prick with pleasure.

"That's it," Luke urged. "Cum for me."

"Shut up," she told him.

She felt him grin against the skin of her breast.

Luke pushed his hips forward and then snapped then back sharply, repeating this several times before he felt Penelope still above him. All the air left her body and she squeezed her eyes shut tightly as her creamy thighs clenched and shook and her body vibrated with pleasure.

A warmth hit the tip of his cock and he felt wetness slip down the rigid appendage, leaking onto his balls.

That's what did it. That's what sent him over the edge.

He buried his face in her ample chest and groaned.

Neither of them moved as they struggled to regain their composure and get their breath back.

When Penelope pulled back to look at his face, there was a smirk of satisfaction spread from one corner of his mouth to the other. He wiggled his eyebrows at her for extra effect.

"Asshole," she muttered under her breath.

He just chuckled.
