Part One - Resolution
"Urgh! For fuck's sake!"
Jake dashed from the living room into the kitchen. Isla stood at the counter, gripping the countertop in her hands. Her head hung, long dark hair covering her face. Her briefly focused on the roundness of her ass, bulging through her jeans.
"What's wrong?" he asked, concerned for his flatmate.
"There's not a single fag in the flat! I've looked through every cupboard, every drawer!"
"Well, yeah," replied Jake, relieved it wasn't something more serious. "You threw them out. Or gave them to your mates."
"I know, but I thought I must have missed some! I'm never that thorough." She turned to look at him, a pleading look on her face. "You don't have any, do you?"
Jake shook his head.
"I haven't smoked in years, you know that." He stepped over to her, putting his hand on her slender arm. "I know it's tough, but you can make it. It's only been a week."
"I know! That's what's so fucking awful! I've barely made it through a week, how can I keep this up?"
Isla had given up smoking for New Year's. She'd managed to cut down from ten-a-day to five over the last few months, and thought a New Year's resolution was the perfect opportunity to give up for good. She hadn't really believed just how tough it would be.
"When I was giving up," said Jake, "I was on nicotine gum for weeks. You should get some of that."
"No, that's no good. It's just giving up one hook for another."
"Well, you were looking for a smoke just now," he pointed out.
"That doesn't count," said Isla, convincing neither herself nor her flatmate. She'd idly picked up a pen off the counter and was flapping it about in her hand. Looking around, she absently put it in her mouth, moving it around with her tongue. Jake felt a brief surge of arousal at the sight.
He and Isla had lived together for a couple of years now, matched up by a mutual friend when they both needed somewhere to live. They'd both had a few partners over that time, nothing ever lasting longer than a few months. Jake had developed a huge crush on Isla, and she knew it, but she never really minded. It was flattering, and aside from a little flirting, it never really came up. Certainly it never bothered her. Sometimes she heard Jake wanking in his room, the tell-tale slap and occasional grunt giving it away when he thought she wouldn't hear. It turned her on just a little to imagine that maybe her was thinking of her when he did that.
Isla was about average height, reasonably slim, with a decent pair of tits and, she didn't mind admitting, a pretty fantastic butt. She thought she was quite pretty, and plenty of men had been into her over the years. Jake thought she was beautiful, with a stunningly gorgeous body, and he never missed an opportunity to check out her ass when she was turned away from him. For his part, Jake was fairly tall, averagely handsome, also dark-haired. He'd always wanted to be a little taller, a little more muscular, a little better looking. Isla thought he was pretty nice to look at, nothing to get in a twist about. Not that she hadn't wondered about it from time to time.
She caught him watching her as she rolled the pen around her lips.
"What?"
"You need something to take your mind of the craving," he said. "Something to do with your hands and your mouth. If you're not going to smoke or chew gum, or use vapes or anything else you could get addicted to, you'll need something else."
"Don't suggest food. I don't want to get fat."
Getting fat would just make that ass bigger, thought Jake, but shook his head.
"OK... what else could you use your mouth for...?"
He chuckled as the obvious suggestion popped into his head. Isla got there a split second later.
"Oh, don't be disgusting!" she snapped, half-jokingly.
"Well, it would be something to do with your mouth and your hands," he noted, "and you did say you enjoyed it."
Ah, shit, she thought. Never get drunk and let things slip to your horny flatmate.
"I with I'd never told you that," she said. It was true, she did really love sucking cock, but that wasn't the point. "I don't even have a boyfriend right now," she pointed out.
"Like you'll ever have trouble getting one," he pointed out. Getting turned on and suddenly feeling self-conscious, he turned to leave, but couldn't resist adding, "or I could always take one for the team!"
Isla sighed and shook her head, promising herself that she had to cut down the flirting she allowed between them. Still, she couldn't fail to notice the bulge in his pants just before he turned to leave.
Part Two - Cigarette
Hours later, Isla lay on her bed, scratching at her arms and biting her lip. The craving was getting worse. She looked to her bedside table, at the collection of chewed up pens and pencils she had left in her wake. Jesus, this was getting ridiculous. It wasn't just the craving for nicotine or the sensation of a cigarette in her mouth. The conversation with Jake earlier had been running through her mind. She'd even watched some blowjob porn on her phone, silently in case he was listening, and quickly made herself come, but that had only made it worse.
After another ten minutes lying there, unable to get the idea out of her head, she slapped her hands down onto the mattress and pushed herself out of bed. She stormed into the living room, where Jake was watching TV.
"OK," she said breathlessly, before she could change her mind. "Let's do it."
Jake turned to her, still half-watching his show.
"Do what?"
"I'm going nuts in here. I've got to go back to work tomorrow and unless I think of something I'm going to be awake all night fighting these cravings."
"So...?" he added, not quite able to believe what he hoped she might be getting at.
She sighed anxiously.
"I want you... to let me... suck your..." she stopped, an overwhelming surge of embarrassment washing over her.
"Woah," said Jake, standing up, "that was just a joke. I mean, it's not that I wouldn't... you know, I would, but... wouldn't it make things weird?"
She looked him in the eye, setting her face so he knew she was serious.
