Prompt 18: "Stop biting that bloody lip."

Summary: Patrick is unprepared for Shelagh's attack of pregnancy hormones. I'm eliminating the miscarriage scare for the sake of this story and because poor baby Shelagh didn't deserve that!

A/N: THIS PROMPT IS M-RATED PROCEED AT YOUR OWN RISK. Like, it's just smut. Okay, that's all.

Disclaimer: I own nothing.

"Shelagh, I really have to go this time." Patrick was honestly trying his hardest to get downstairs and out the door to the surgery, but Shelagh was making that next to impossible. She'd woken him at 5am with less-than-subtle movements of her fingers on his thigh and soft nips of her teeth along his shoulder. They never went back to sleep. Now, though, it was 7:30 and truly, if he didn't get out of bed soon, he was going be embarrassingly late.

"You don't have any appointments until 10." Shelagh grumbled as she kissed her way across the back of his neck.

"I have rounds before then, love." he sighed in tortured frustration as she doubled her efforts and wrapped her legs around him from behind. He'd finally made it to sitting on the edge of the bed, which was much further than he'd made it after round one, but she was apparently determined not to let him escape. "When did you develop such a disregard for my schedule?"

"I didn't," she giggled, "I just decided you were better scheduled here." She punctuated her quip by sliding her hands from around his waist to between his legs.

He was going to be late.

He finally stumbled into the surgery at 10:30 after frantically completing his rounds and praying that none of his patients noticed that he'd pulled his jumper on backwards after his nearly humiliatingly fast round three with his wife...his wife who was sitting at her desk looking as prim and proper as ever with her perfectly pinned hair and blouse only just pushed out by her four month pregnancy belly. Nurse Mount gave him a clearly questioning look at his haggard appearance, but he ignored it and marched speedily to his office without another glance at Shelagh. He couldn't afford to look at her anymore today. Lately, it seemed any time they made eye contact, their clothes were on the floor ten seconds later. It was only partially his fault, really. He'd grown so used to being the lead instigator in this aspect of their marriage that when her morning sickness stopped and her hormones kicked in, he was more than pleasantly surprised. He loved his bold, challenging Shelagh and was more than happy to let her take the lead. Until, of course, her desire became insatiable and it became everything he could do to keep up with her. It was rare that he felt the age difference between them, but he was sure his exhaustion was starting to become visible to everyone and he wasn't sure he'd be able to think of a good excuse if anyone asked why he was so tired.

He supposed he could refuse her, but really, he knew he never would. Aside from the fact that he couldn't bear the thought of refusing his pregnant wife anything, he wanted to be with her. He expected that their sex life would calm slightly as their marriage went on, but in reality, the only things that slowed it down were interruptions from others. If they weren't both so dedicated to their work and they didn't have two children with a third on the way, he wouldn't have been surprised if they were together nightly. Truth be told, he supposed those obstacles could be gotten around. Shelagh had certainly proven that over the past week…

The knock on his door at the beginning of his lunch hour didn't surprise him and he happily looked up, expecting to see Shelagh with their lunches in hand. His favorite little spitfire did indeed enter his office, but instead of leaving the door open and walking to his desk, she locked the door and leaned against it with a familiar gleam in her eyes.

"Hello darling" she greeted with a shy smile before slowly making her way towards his desk.

"I know what you're doing and it won't work." Patrick tried to stop her with a grin. "Shelagh Turner wouldn't dare." he felt confident in his assumption that she wouldn't actually have locked his office door for that, but when his teasing didn't seem to phase her, he got a little worried.

She stopped at the edge of his desk.

"Maybe you don't know Shelagh Turner as well as you think." Her voice dropped and she caught her lip between her teeth, somewhat shocked at her own brazenness, but unable to focus on anything else.

She was killing him.

"Stop that." he nearly growled.

"Stop what?" she asked completely innocently. God, she really had no idea and he didn't know how to handle the flushed temptress in front of him when she genuinely didn't understand how seductive she was being behind the overwhelming push of her hormones.

"Stop biting that bloody lip, Shelagh." he warned. "I might not be able to control myself if you don't."

She flushed even deeper and he saw the war in her eyes between her desperation and her modesty. He wasn't sure which one he wanted to win out at this point. They shouldn't do this here and had frequently stopped themselves before, but he didn't know if four-months-pregnant Shelagh would want to stop and the idea thrilled him as much as it terrified him.

He saw the minute her resolve broke.

"I don't think I want you to control yourself." she whispered.

"Love, are you sure?" he forced himself to ask one more time before they both did something they would regret.

"Please, Patrick." she begged.

He broke.

He threw himself out of his chair, rushed over to her side of the desk, and kissed her roughly, tugging on her swollen lip with his own teeth. His enthusiasm lifted her off the floor and he groaned as she wrapped her legs around his waist. He had originally cursed the day she abandoned her tight pencil skirts for looser dresses, but now he was eternally grateful for the way the fabric let her move uninhibited around him.

He unceremoniously dropped her on the desk. He would apologize later. He needed his hands.

Her skin was searing, even through the light fabric of her dress, and she keened at every touch as though they'd been apart for months and not ravaging each other that morning. That part of her, at least, was consistent. Once she fell over her wall of insecurities, she was fully committed to their sexual adventures.

Shelagh knew that increased desire was a common side effect of pregnancy, but she wasn't prepared at all for when it actually hit her. She loved sex, and she loved Patrick, but suddenly it wasn't just love, it was need. Pure, unadulterated need. She couldn't focus, she couldn't sleep, and she constantly felt like she wanted to crawl out of her skin with how sensitive she was. It was as if they only thing in the world that made her feel calm was her husband's touch and really, that didn't make her feel calm at all.

He was wearing one of his blasted jumpers today; she couldn't even rip it off him. He must've sensed her frustration and he stepped back and quickly tossed off the jumper, his shirt, and his vest in one go. The feel of his warm chest against her palms sent relief soaring through her and she dragged her fingers down his stomach to the button of his pants as he shivered.

"God, Shelagh, you're insatiable." he grunted as he slid his hands up her skirt and bit down hard against her neck. He wanted her dress off, but there wasn't time and her desperation was contagious. His fingers found her at the same time hers managed to sneak beneath his shorts and they both gasped at the jolt of pleasure.

"Patrick. Need. You." she panted as he pulled her panties aside. Her head fell back when he slipped two fingers inside of her and he groaned at the vision of wantonness she made before him. She was still oversensitive from their relentlessness that morning and he quickly shoved two fingers of the hand that wasn't making her see stars into her mouth to stop her growing volume. She was surprised at how much she welcomed the intrusion and sucked at his fingers. The sensation combined with her eagerness sent him reeling and he suddenly didn't care about making her come before they were joined. It wasn't as if it was going to take much to get her there anyway.

She whimpered at the loss of his fingers, but then shot up into his arms as he entered her without warning.

"Yes, yes, yes." she chanted into his shoulder as he dug his nails into her backside to steady them both. He had no idea where his stamina was coming from lately, but god, was he thrilled about it. Her insanity bled into him and threw his logical mind into a messy haze where nothing existed except the incredible feeling of her throbbing around him.

"Oh, Shelagh." he sighed. "So. Good."

He heard the high pitched whimpers in the back of her throat and knew she was close. He slammed faster against her and ignored the sear of pain as she bit into his shoulder when she came. Her seizing muscles drew his own release out of him and they collapsed onto the desk in a pile of sweat and heat.

"Feeling better, love?" he asked cheekily.

She blushed into the roots of her hair.

"Yes." she shyly admitted. He marveled at her ability to look that sweet after what they just did, and in his office, no less. "I don't know what's gotten into me lately."

"Well, I imagine it was me." he grinned. She rolled her eyes and laughed. "I do want you to eat something before break is over. In all seriousness, as much as I love your enthusiasm for physical activity, I worry that you're not eating enough."

"We're both fine, Patrick." she assured. "I promise I'll eat some lunch."

"Thank you."

He put himself back together and she gently hopped off the desk to grab their lunches.

"Patrick?" she called from the door.

"Yes?"

"Don't wear a jumpertomorrow." she instructed with a smile as she headed out of his office and past a winking Patsy.

18 down, 32 to go! Hope you enjoy!
