Okay, guys, this story is completely a long-shot.

I wrote the start, as you can probably tell, based off the Wolfman movie, and I had absolutely no plot whatsoever, rather a kind of... kinky..? thought about the movie, but I wrote this out and it all came into a rather cute and nerve-wracking story... well, in my opinion, anyway. So excuse the parts where there's not much sense :)

Pairing is, definatly, Alvin and Simon, so please, if you hate these two together, do yourself a favour and don't read it, because it's not worth your time. There are over 2320 fanfics in this category that you could read other than this.

To all the fans of these two, I hope you enjoy this, and I'm always happy to write for this pairing,

:D

'Simon, please –'

'Alvin.' Simon gave Alvin a look he couldn't argue with and Alvin hung back, folding his arms. 'I need to check, Dave's or –'

'I know!' Alvin exclaimed, 'I know it's "Dave's Orders", but after a week, I don't know what you expect to find! There is no more monster stuff in my room!'

'Our room,' Simon corrected, 'and I can't be sure.'

Alvin glared and paced his side of the room, Simon looked around; under Alvin's bed; behind books on the shelf – luckily, he never noticed the book hidden behind the pillow on the windowsill.

Simon suddenly turned sharply to Alvin, who was beside the window, and stormed forward. Alvin worried if he'd seen the book.

'Spread 'em.' Simon ordered, pushing Alvin against the wall while turning him around so his back was to Simon.

'Th-there's nothing on me, I swear,' Alvin insisted. Simon rolled his eyes and reached far into Alvin's left pocket, straight away finding a toy wolf. 'That's not – I can explain –'

'Of course you can,' Simon chided, dropping the toy into his box. He turned back and reached again into Alvin's pocket.

'S-S-Simon,' Alvin shuddered when Simon reached way too far down, 'T-that's not a t-t-toy,' Alvin screwed his eyes shut when Simon ignored him and kept feeling through.

Eventually, Simon pulled his hand out, staring impressively at Alvin, hands on hips.

'I felt something down there,' He told Alvin almost menacingly, 'and don't think I won't get it just because you hid it there.'

'No, S-Simon, it –'

'Strip, Alvin, or I'll do it for you,' Simon ordered. Alvin turned around, shaking his head desperately.

'Si, I'm not kidding, that area's definitely clear –'

'I'm not buying it, "Al",' Simon retorted. He walked closer to Alvin threateningly, but Alvin slipped sideways to avoid being backed against a wall, half terrified of what Simon was suggesting, his mind no longer on the book.

'Simon, why don't you believe me?' He asked desperately.

Simon raised a brow. 'You're seriously gonna go with that question?' He asked, 'Now you're just desperate.' He kept walking towards Alvin until he'd managed to back him to Alvin's bed.

'Simon!' Alvin protested. Simon rolled his eyes and pushed Alvin on the bed.

'Will you strip, already?' He demanded mockingly. 'Because I am not kidding about reversing that. Final offer, Alvin.' He leaned dangerously over Alvin, who was in a sitting position off the edge of his bed.

'Gosh, Simon, trust me for once!' Alvin pleaded. Simon frowned as though his older, red-clad brother, was crazy, then pushed Alvin down slightly.

'Look, Alvin,' he began, placing his hands at Alvin's hips, 'I don't want to do this any more than you want me to, so if you –'

Alvin grabbed Simon by the waist, pulled him on top of him and flipped them over, so he could straighten Simon out.

'Simon, there is no toy down there.' He promised darkly.

'Then what did I f –?'

'Shush, will you?' Alvin scolded. 'That was a... it was me... responding to you... touching me... down there...' He figured slowly. Simon's eyebrows rose.

'You had an errection?' He concluded. Alvin blushed and nodded slowly. Simon then frowned. 'Wait, for me? Alvin, that is not good.'

Alvin scoffed and got off Simon. 'It's no big deal.' He replied passively, brushing aside the conversation; but Simon took it right back.

'Don't say that, Alvin,' he protested, 'it's a huge problem!'

Alvin chuckled. 'I wouldn't say "huge"...' he joked. Simon sent him a small glare.

'Does the word "mate" ring a bell for you, juvenile?'

Alvin frowned. 'As in... how the Australians call their best friends..?' He guessed. Simon rolled his eyes, standing and pacing slowly in front of Alvin, who wasn't quite as phased by the events.

'How about "Spring"?' Simon tried. Alvin shrugged.

'Dunno what the season has to do with this, but –'

'"Heat"?' Simon raised his voice. Alvin frowned, perplexed as to where this was going, unsure if Simon was okay or not.

'Simon, it's not a big –'

'Alvin!' Simon interrupted loudly. 'It's a problem! You and I are ten this year, and...' he paced a bit faster. Alvin still had no clue as to what was wrong with his younger brother.

Tentatively, he stood. 'Are you okay, Simon?'

Simon sent a glare Alvin's way, then took him by the hand out of the room, down towards the basement. Passing Dave on the way, he told him he would be helping Alvin with homework and would be locking the door. Dave didn't have time to respond before Simon had dragged Alvin through the door, locked it, and pulled him down the stairs.

'You know, you could have just said, "let's run down to the basement",' Alvin insisted once Simon had let go of him. 'I can walk, he cleared up, straightening his shirt then cap.

'Alvin, just let me straighten this out;' Simon halted. 'Do you, even consider, having feelings for me?' He blandly asked.

'Uh...' Alvin frowned. 'What kind of feelings?' He asked. Simon sighed, annoyed at Alvin's slowness.

'Alvin,' he began, 'Chipmunks are supposed to feel heat in spring and mate.' He clarified. 'I'm asking if you think of me as a possible interest, with feelings brothers shouldn't have for each other. Feelings that only occur in spring if chipmunks are over eight or nine years old.' Simon locked gaze with Alvin. 'Do you or don't you consider these feelings?'

'Towards you?' Alvin cleared up. Simon nodded. 'Well, no, but I can't help... thinking about it now you've said...' Alvin shrugged.

'Do you like it?' Simon made each word as clear as possible.

'It's, uhm, weird, yeah... I don't like it, but... I'm not... too grossed out by it, either.' Alvin admitted. Simon looked as though he was trying to remain cool-calm-collected.

'In... In a chipmunks usual life...' He began slowly, 'we don't experience many differences to a human, but the thing that sets us apart is... spring.' He paused here, gathering his words. 'In spring, a chipmunk will undergo something called "heat". At any stage in life, there will be some form of this urge. A lucky amount of chipmunks find a member of the opposite sex (or same, if preferred), and may claim a "mate".' Simon gave Alvin a cautious look here. 'Once one of the two claims the other, the other must comply, even if they don't want to. It's the order of nature; a law.

'Usually, it's a male claiming a female, not opposite, but that's not certain. And both newly appointed "mates" will have to learn to love each other, even when one was not willing.' He took a breath, but Alvin interrupted.

'Wait, what's this got to do with us?' he questioned provocatively.

Simon sighed. 'I'm getting there.' He insisted. 'In our case,' he motioned to himself and Alvin, 'we were not available for any female for us to claim, and the majority of chipmunks claim a mate at five. It's preferred. So, that didn't happen with us.' Simon motioned for them to sit, and they did so slowly. 'and don't assume that we needed another chipmunk to vent our spring heat to, because spring came and went and we only had each other. Instead of claiming a mate, we needed to find other ways to fulfil our spring heat. Things we used to do, like sleeping so close, and actually having a verbal relationship –'

'What do you mean by that?' Alvin mused thoughtfully.

'Most chipmunk siblings don't talk. Their main goal is to find a mate, reproduce their species, and die knowing they've completed their life-cycle.' Simon admitted sadly.

'That's a horrible image...' Alvin muttered. Simon nodded to agree.

'Like I said, this didn't happen to us.' He continued, 'we passed three more springs, and many urges, until we'd matured, and realised we couldn't find a mate. By almost seven years old, we were with Dave. Not only had we found a bigger meaning to life, we weren't tempted to mate anymore; our goals were sidetracked to a human reality.' Simon smiled. 'We were very lucky.'

'So... why are you interrogating me, again..?' Alvin asked in confusion.

Simon sighed. 'Well, I said we couldn't have found a mate, but... we could have. Only, we were far too young and confused to realise it.' Simon went on, now frowning in memory, not looking at Alvin. 'It's very rare for a chipmunk not to find another to mate with. Even more so there were no females around us. We had the... very... very, very rare resort of mating with each other...' Simon shook his head. Alvin had an "oh, I get it... yuck" look on his features. Simon continued. 'Mating within the family is not unusual for a chipmunk, well... it's not considered bad, anyway. It was a resort we could have taken.'

'But, we wouldn't,' Alvin got out. Simon shook his head.

'It would have happened, to vent our urges, if not for Dave.' He looked worriedly at Alvin. 'But it wouldn't have been Theodore's problem. He was, and still is quite, too young.' He set a locked gaze with Alvin. 'You and I would have mated. Only to fulfil our "heat", without care.'

Alvin nervously swallowed. 'S-so we would have... we'd be... be "mates", i f Dave hadn't found us?' He figured. Simon nodded.

I'll end it there, and I'm sorry if there's an awkward ending every now-and-then, but I wrote this story out fully on paper, without chapters included XD

I hope it was (is) okay, though, and I'm going to continue it if there is even one positive review.

Thanks :D
