A/N: This is my first fan fiction on this website. My awesome Betas, Way Worse Than Scottish and FireWhiskeyDays really helped pull it all together. Special thanks to Way Worse Than Scottish for adding in River's catch phrase, 'spoilers, sweetie'. This is a two part fic. I've rated part one 'T', and part two 'M' because of the smut. Part one can stand alone if you don't want to read about sexy times.

The Phone Call

River hadn't been working at the university for very long. It had only been a few months really, and she didn't want her students to think they could get away with any nonsense in her classroom. Luckily, she wasn't having any trouble swaying college students to take her class, and always had a full hall of students eager to learn. She was sure it had nothing to do with her failure to follow the school dress code; she found it much too stuffy and conservative anyway. Today, for example, she was wearing her black leather pants, a red blouse that hung down in the front showing her ample cleavage, and daringly high black heels. If you've got it, flaunt it, River always thought.

Her current lecture was on one of the duller archeology topics, and none of her students were paying much attention. She sighed, and then glared at several of her students, who quickly stuffed their cell phones back into their pockets when they noticed her gaze. The year was 2006, only the beginning of the technological advancements on Earth, and it would only get worse with time, she reminded herself. Still, that was no excuse, and she was already annoyed about the lack of air conditioning in the lecture hall. River resumed her lesson on the different types of fossils, but was quickly interrupted by the loud ring of a cell phone.

"Who didn't silence their-," River stopped mid-sentence when she realized that the phone ringing was in fact coming from her own bag. "Shit," she whispered under her breath as she started to dig around in her bag trying to find the damn thing. A few students snickered, and River gave them an apologetic look. She gasped when she realized it wasn't her normal cell that was ringing but her communicator, a direct link to and from the TARDIS.

"Umm, I have to take this," she muttered, absently casting her eyes over her class as if daring them to be too loud. She clicked a few buttons on the communicator and held it up to her ear. "This better be important," she nearly growled into it. The Doctor knew better than to interrupt her classes.

"What, I don't get a 'hello sweetie'?" The Doctor asked in his best pouty voice. She didn't answer. "Anywaaays," he said trying to procure a more serious tone, "I need you. And, um... It's important," he added.

"Are you in trouble?" she asked in mock concern, looking around at her students' questioning faces. She was worried, but it wasn't like he couldn't take care of himself. Yes, he was known to get himself into some sticky situations... and in fact she had already had to save him twice this month. She changed her mind; the Doctor really couldn't take care of himself. It sounded to her like he was trying to make light of the situation; which was something he did when he was nervous. "Oh yeah, loads of trouble, I think you need to get out here right away," he said with what River assumed to be a smirk on his face. "So where and when are you- I'll come get you," he prodded, clearly way more excited than he need to be.

"Sweetie," she said warningly, "you need to tell me what's wrong right now. I'm in the middle of a lecture, and a classroom of college kids are staring at me."

"Oh, OH," The Doctor said suddenly in understanding. River huffed, but smiled for her class.

"Is this something we can talk about later?" She asked.

"Oh, erm, not really," said The Doctor. "You see my problem is that I miss my wife. It's just me and the TARDIS, because your parents are away on holiday. So I really need you here with me. Right now, River." River could hear the desire on his breath when he said her name sending a shiver down her spine.

"What kind of problem is it then?" River asked, smiling lightly.

"An intimate problem," he purred. She fought the shiver that went through her.

"And you need my help to fix it?" she asked, playing dumb.

"Oh River, I think you're the only one who could fix it," he said, his voice deepening all of a sudden.

"Oh, really?" she quirked an eyebrow.

"I'm sure you have many ways to fix my… er, problem," he said in a low tone.

"Spoilers, sweetie," she teased. Oh, she was enjoying this.

"Oh, forget about your students and your spoilers, River, and come!"

River looked around at the classroom, and then back at the phone. "My class is over in thirty minutes, can you meet me after?" She said with a hint of urgency on her breath.

"Thirty minutes, oh no River that's much too long," he whined.

"I'm sorry sweetie, you'll just have to wait," she sighed. It really was too long, she thought, already aroused by what most certainly awaited her.

"Oh, the things I will do to you for making me wait," he growled in the most primal and sexy way, making her knees go weak. She reached over to support herself on her desk.

"I can't help that I have a class," she playfully snapped.

"Does it matter?" He replied cheekily. Oh she could practically hear his smirk. Damn him.

"I'll see you in thirty minutes in my office," she said, quietly adding 'April 12, 2013 3pm' under her breath so he could hopefully get the time right.

She hung up the phone, and for the first time that day her entire class was focused on her.

"Who was that?" a student asked from the back row.

"My husband," River answered. She marveled at how intrigued the students could get into their teachers personal lives, not that she was going to share any more with them.

Students blurted out questions and whispered amongst themselves about what she might have been talking about to her husband. Most of them didn't even know she was married. She stopped the whispers by making up a semi-convincing lie in which he had lost their house key, while she desperately tried to draw their attention back to the lesson. Unfortunately, she was having trouble focusing herself. Her mind wondered to what the Doctor had planned for 'the things he would do to her for making him wait', and how she could get back at him for putting her in such a state in front of her pupils.

A/N: Part two to come very soon! It'll be a bit longer as well. Please review.
