A/N: I thought this tale would have finished by now, but I can't seem to stop adding in bits. Sorry.

Part Five

.

Placing his mobile phone to his ear, Chris brightly said, "Hello, love! What can I do for you today?"

There was a slight pause on the other end of the line. "Chris?" Donna sounded perplexed. "It's me, Donna. Are you okay?"

"Couldn't be better." The grin was all too evident in his voice.

"Did you get lucky last night? I take it the experiment went well," she surmised. "Well, it would go better with your friend the Doctor helping you."

"He told you that?!" he practically squeaked as he hastily tried to sit up, felt a bout of nausea try to break through his skull, and looked around for his glasses. Damn! Where had he thrown them?

"It wasn't a state secret, was it?" she queried. "Don't worry, he didn't tell me what exactly you two were up to."

Chris groaned as he held onto his head; or rather tried to hold it in place. "No, I won't. Did he erm… did he… was… what did…?"

Donna sighed. "Chris, I promise to tell you whatever you want to know, but I have to actually have the question first."

At that moment he spotted his glasses, and reached out to grab them almost without toppling off the sofa. "Okay, here goes. What did you think of him?"

"Nice. He seemed very nice," she said. Blimey! That must be the understatement of the century. "A bit full of himself at times, and intense, but all in all I liked him."

Chris wiped his hand down his face, feeling his good mood slipping away. "And did you erm… was there any… have you made… plans to see him again?"

Oh! Hadn't the Doctor told him? She thought they were close friends. Then again, did that mean something else? "I won't lie to you, Chris. He overwhelmed me quite a lot last night, what with all the talk and smooching. Is he like that with every woman he meets? Because it would make perfect sense to me if he is a serial hit and run driver." Donna then let out a small sob. "I've been a total silly cow, haven't I? I can't believe I actually believed him for five seconds. God, I am thick!" she declared despondently.

What? Oh no no no no! "Donna, you are not thick," Chris firmly insisted, not knowing quite how to play this. "I'm sure he thinks a lot of you."

"Yeah, nice try," she stated as she wiped at her eyes desperately. "It serves me right for being taken in. I'm sure you'd never treat a woman like that."

He heard her sad sigh and wanted to immediately hug her close. "Why don't I come over early and we can have a nice cuddle in front the telly this afternoon? Just name a box set of DVDs and I'll bring it over."

"Oh Chris!" She then frantically wiped even more tears away as she considered his thoughtfulness. "What would I do without you? Apart from have no one to cook massive meals for, I mean. Bring something we can bitch about; and can you pick up some decent ice cream on the way?"

"Anything for you, love," he eagerly replied, and felt a warm glow within his chest when he came off the phone. This was beginning to look promising. With that in mind he eyed the rest of his potion suspiciously. Was it wrong to have used it if it gave him what he wanted? Well, it wasn't as though he would have to use it again…

As he stood on her doorstep he wanted to greet her with the words, "You ordered a large cuddle" but when she opened the door and weepily flung her arms around him it seemed slightly out of place to do so.

Within minutes he had her settled down on the settee, some innocuous DVD in the player, and the kettle on for a calming cup of tea. Handing her a mug, he plonked himself down cosily next to her and opened with the question, "Do you want to tell me all about it?"

She nodded, put the mug down and wrapped her arms around his body, leaning her head on his shoulder; making the most of being able to do this with him as she felt him return the embrace. Okay, she was beginning to feel a bit of a fraud at this point, but when the opportunity presents itself… "You must think I'm a right div acting this way. But he reeled me in hook, line and sinker."

Chris smoothed a hand over her hair. "What on earth did he say?" he wondered.

"Some flowery things, but it was more how he said it, making me feel special," she explained.

"Well, you arespecial," he blurted out, and ignored the inevitable derisive snort from Donna.

She then surprised him by asking, "Are you related to him?"

Oh! How should he answer that one? "Erm… yes, actually," he said guiltily.

"I thought so," she mumbled next to his chest. "There's quite a family resemblance; not that I'm saying you go around seducing women just for the fun of it. In what way are you related?"

Near panic made him mutter, "On my dad's side. He had some traits my mother wasn't too keen on."

There was a muffled yawn as she nestled more into his chest. "I don't blame her," she said before drifting off.

Chris didn't mind too much; it meant he could indulge in running his fingers through her hair to his heart's content for the next hour or so. After that she woke up and insisted on cooking him a dinner, so it was a win-win situation.

Well, it was until he got home when that damn bottle of mixture called out to him to prove her wrong and use it again.

Donna was just about to change into her nightwear when her doorbell went. Thinking it was probably Chris complaining he had forgotten his wallet or something, she didn't hesitate to open the door, and was shocked to see the Doctor standing there.

"YOU!" she spat at him.

"Hello, Donna," he said smoothly, looking very unruffled. "I hear you've been casting aspersions against my character. Tsk tsk! This won't do. And after all the lovely things I said about you."

"If you didn't go around acting like a conceited prig then I wouldn't have to," she defended herself.

"You wound me, Donna Noble," he replied, placing his hands over his heart. "Up until now I thought you might be the one."

"The one what?" she queried, glaring at him.

"I know, let's carry on discussing this on your doorstep for all your neighbours to hear," he sarcastically replied instead.

Her cheeks flared in embarrassment. "I suppose you'd better come in then. But you are not staying here long, so don't think that you are."

He stepped into her small hallway, and swept his smug smile towards her. "As if I would ever do anything to upset you. No, I'm here to apologise and let you say sorry to me in return."

"Sorry? Why should I say that?" she asked.

He moved closer to her, almost wedging her up against the lounge door. "You know exactly why," he said as he brought up a finger to trail it down her cheek. "I hear you spent the afternoon canoodling with Chris."

"And what if I was?" she asked defiantly. "It's got nothing to do with you."

He shook his head. "Au contraire, mon amour. It matters a great deal to me, since I laid a claim on you last night."

Her hand shot up to slap him hard, but he deftly caught it. He then had the cheek to chuckle.

"What's so bloody funny?" she demanded to know as he held onto her wrist. She'd be blowed if she'd allow him to intimidate her.

"You are, my gorgeous, darling, fiery ginger," he near whispered, rubbing his nose seductively along her jaw. "I love the way you react." He then almost freaked her out by taking a deep sniff next to her throat. "I love so many things about you."

"How can you say that? You hardly know me after one night of dancing," she retorted.

"And kissing. Don't forget we were snogging each other; and very nice it was too." That irritating self-congratulatory smirk was back.

"I think you should leave," she announced.

"No!" His eyes shot daggers at her, and then he spoke more gently. "No, Donna. I won't leave you yet. We have too much to discuss."

What was he on about? As far as Donna was concerned they had nothing to discuss and she was completely over him. Her unrequited love for Chris was enough to see her through. She was totally unaffected by the Doctor's enticing scent, his dark eyes that were so soft and intense at the same time; that mouth that suddenly made its way onto hers, sweeping away every carefully placed argument she had built up in order to ward him off.

A groan or two forced its way out as their lips glided together in a hot, seductive dance. Her mind fought hard to battle against this delicious feeling but it was as though something was forcing her to ignore every single counter argument and focus only on how good he made her feel.

It almost worked, because she jolted when she realised his hand was once again on her bottom, tenderly caressing it. He hardly batted an eyelid as his other hand kept her head in place, and he crooned in her ear, "You are sobeautiful."

Her mind buzzed with delight; and all she wanted to do was kiss and kiss him before he disappeared out of her life forever.

It was quite weird when he broke from her with a strangled cry; his eyes blown wide open. Anger then raged on his handsome features. "That little sub-human!" he cried. "I'll get Chris back for this."

Sub-human?! What exactly did that mean? She truly hoped Chris hadn't done anything stupid on her behalf. "Why? What has he done?" Donna asked in shock.

"Something he'll regret," the Doctor merely answered darkly. "Nothing for you to worry about," he added deliberately lightly as he quickly pecked a kiss on her mouth. "I'll see you soon."

With that he was gone, out into the night; so Donna hastily texted Chris to let him know the Doctor was on the rampage.

She then sat staring at her phone, thinking, 'Ring! Why don't you ring?' as she waited for a reply. How did she really feel about the Doctor? Her mind was in such confusion, as if a spell had been cast over her where he was concerned. She liked kissing him, she knew that; and he absolutely filled her head when she was with him. But when she was back on her own, Chris was all she wanted to think about. Why couldn't she be happy with the one man that had offered himself to her in recent years? Why did she always want the unobtainable?

Taking a deep breath, she decided she would make the most of this opportunity after having told Chris the absolute truth. He deserved to hear it from the horse's mouth. Although perhaps she'd leave out the bit about fantasising it was Chris she was really kissing? Yes, that part could be very shaming.

With that decision made, she took herself off to bed to see what her dreams would bring.

For his part, the Doctor was furious as he stormed back to Chris' house. The little pipsqueak had tampered with the strength of the potion, making it nigh on impossible for him to stay the night. Well, he wasn't going to let that detail escape his attention next time.

But as he opened the front door his strength was already rapidly waning; and by the time he climbed the stairs he was almost out cold.
