A/N: Hello all. So, here's the thing. I actually wrote this originally as part of chapter one, but cut it short for later use. So here it is. I do not own Doctor Who. Also, I love reviews, so should you feel the need... (hint hint, nudge nudge). And last but not least, hi Lurkers!

A/N take two: Oh, almost forgot. Since the first chapter is pretty smutty, I will be providing a summary at the end of this chapter to give the general gist of the story to those who prefer to avoid the smut. I will post a notice at the beginning of Chapter 1, too. Happy Reading!

Chapter 2: An Explanation

The next time River woke up, the Doctor was pacing back and forth in front of her bed. River lay still and watched him move, fast and furious, hands behind his back, and considered what had happened. She had woken up, she remembered, and the area between her legs had hurt… River gave an experimental twitch, and was pleased to discover they no longer hurt so much.

Then, River thought back further. Let's see… she had come into the TARDIS, moved it to safety, and then the Doctor… Oh. River glanced at him again, still pacing, still ignorant that she was awake. She cleared her throat.

The Doctor jumped, startled, then turned and hurried to her side.

"River? How… How are you feeling?" He took her hand and stared into her eyes.

"I'm fine, Doctor." She replied. "Nothing… hurts now." She blushed and looked away. The Doctor cleared his throat and said:

"I can explain, River." he released her hand and sat down in the armchair, leaning forward to look at her. "You know about Time Lord instincts, I assume?" He raised an eyebrow, and waited till she nodded.

"A little."

"Well, here's the thing. You know that women have their… fertile times, right? Well, with Time Lords, unlike most other species, the males also have certain… times. Sure, we're fertile all the time, but the marriage rite of a Time Lord is so intimate that it literally alters the genetic make-up of said Time Lord, even deeper then regeneration. So that, well. Time Lords usually marry other Time Lords, and after a certain amount of time, at certain intervals in a marriage, the Time Lord gets a need to impregnate the
Time Lady for about a week, unless he has already done so. Usually, it's about 3 months to 3 decades after the actual marriages, with about the same interval each time for the rest of the marriage. So, depending on the number of Time Lords currently out there, it will happen more or less frequently. And it only stops when the Time Lady is well and truly pregnant." The Doctor paused, took a deep breath. "Which you are."

He looked up into River's shocked face and smiled weakly.

River stared at him, mulling it over, taking it in. Pregnant? The TARDIS had said nothing about… But they had used... No, they hadn't, she hadn't been able to…

Around and around her thoughts went, till her head was spinning. She looked away from the Doctor, staring at the wall. Finally, she decided on a course of action. One step at a time… Without looking at the Doctor, she threw back her sheets and swung her legs over the edge of the bed opposite him.

"River!" The Doctor stood up, alarmed, and moved to go to her. But River just held up a hand over her shoulder and, still not looking at him, climbed out of bed and walked out of the room. The Doctor stared after her helplessly, hands by his sides.

River went to the nearest bathroom, crossing her legs while she opened her secret cabinet and pulled out a long, narrow package. Then, she went to the toilet and peed on the stick. Setting it on the edge of the bathtub, facedown, she slowly finished up and went to the sink and washed her hands. Then she stood staring at a wall, trying not to think, until the TARDIS hummed. It was time. She turned around and picked up the stick.

There was a soft knock on the door, and River poked her head around it. The Doctor lifted his head from his hands; the TARDIS had locked the door, preventing him from following her, so he had been left in defeat to wonder about what she was doing.

"River? Are you… What happened?" The Doctor slowly stood up and moved towards her. River stepped in and shut the door.

"Can Iask you something?" Rive asked, not looking at him. "Why didn't you tell me all of this before? Why, when we've been married for months, did you not find even one moment to tell me that there would be a time when you would attack me and basically rape me?" River's voice cracked on the last two words, and she sat on the bed, holding the bedpost for support, and turned her face away to hide her tears.

The Doctor moved closer and carefully wrapped his arms around her shoulders. "I… I don't know, love. Maybe I was scared of what you might say, or that you might leave, or… something. I had hoped that I could just park the TARDIS on a random planet when the time came, and just wait it out without you coming in. I tried, you know. It's awful, having to pass those times with no respite. So far, this has been the second time it's happened, and you walked in on the first day." The Doctor rubbed River's back as he talked gently, trying to soothe her.

"I tried, I really did… but the thing is, once I smelled you, there was nothing I could do. My animal instincts took over, and…" The Doctor shrugged and leaned over to rest his chin on her shoulder. "Please forgive me."

River stared away, listening. She understood, now, why he'd acted so horrified to see her. He'd been trying to protect her. She twisted in his arms so they were facing each other.

"Oh, Sweetie. Of course I forgive you." River smiled and hugged him. "It's not as if you're the only one at fault here. I didn't exactly protest, did I? In fact, I seem to remember having been quite provocative." The Doctor squirmed, not looking at her.

"Erm… that actually wasn't all you. The… I might have contributed more than a little to you willingness." The Doctor blushed and looked down.

River stared at him for a moment, trying to figure out… oh. Yes. That. Subconsciously, she raised her hand to her neck and felt along the base of her collarbone for the bite mark, now nearly healed, and ran her tongue along her teeth, tasting the raw flesh. Then she dropped her hand and swallowed.

"Still. What's done is done." She turned to him and wrapped an arm around him, burying her face in his shoulder. She sniffed. "You smell nice. Like…"

The Doctor wrapped an arm around her as well, and kissed the top of her head.

"I… you should probably get some sleep. You must be tired." Before River could protest, he had scooped her up and tucked her into the bad they set on. He paused and smiled down at her for a second, then raced out the door, which he closed with a sharp clack, signifying that she had no choice but to rest. River snuggled down and pulled the blanket up, and the temperature in the room dropped to keep her comfortable. She smiled sleepily at the TARDIS in thanks, then drifted off.

Post-note: So, thanks for reading, please review, do not own, etc. And now, for the Chapter 1 summary.

Summary: River runs into the TARDIS intent on hiding from the things she's been fighting with (no idea what, just something to set the scene). Unfortunately, she walks in on an extraordinarily libidinous Doctor, who had meant to stay away from her during this time. So, basically, his instincts kick in, and he jumps his wife (who is not entirely unwilling) and, with the aid of a few Time Lord quirks, succeeds in taking her virginity, impregnating her, and driving her to an amazing and long-lasting climax which causes her to black out. Later on, she wakes up dressed in a nightie and in bed. The Doctor gives her something for the pain which also knocks her out, and then the story picks up again in the above. :D

P.S. : So, that's that. One last thing though. After this one, I'm kinda stuck on where to take this story. I could go the way this story seems to point, or I could go somewhere else. Tell me what you think, maybe give me ideas if you have any. I have lots of material, and I'll try to be flexible. Okay, that's it for real this time. Bye.
