There isn't any reason you need to check out the second bedroom; your best bet would be to follow the scent trail leading into the foyer and see if your supernaturally inclined rodent guest is hiding out in there. However; as you start to make your trek down the hall you start to become a bit self-conscious of another smell just as pungent as the intruding mystery rodent...that being yourself. You pause to take a moment and sniff your arms and chest, being on all fours you even lift one of your legs and stretch your snout underneath. The heady aroma of your spilled nectar soaked into your fur matting hairs into small tangles and minor dust encroached between your thighs causes you to cringe and cover your animal nose in disgust.
Your arousal is one thing, but it is quite uncomfortable roaming the house stained and encrusted in your overindulgence. You're grateful for regaining your human mental faculties assuming being nothing more than a wild instinct driven animal would leave you ignorant to good hygiene. You are not ready to personally groom yourself in such baser fashion...at least not when your covered in god-only-knows what.
You turn your gaze to the bathroom door left a crack open, deciding in that instance you can't continue your investigation until you clean yourself up proper. Scurrying across the hall you slip through the crack and enter your bathroom, your nostrils pleasantly surprised prepared for a bombardment of nasty grime and waste a bathroom stall can have. But; thankfully, you do a better job than most keeping this private facility clean. Even the floor itself doesn't stick to your paws as you scamper onto one of the floor mats next to the sink counter and drawers.
Looking around the restroom, still astounded by how crazy your world feels being this small and everything else towering, you start to question how exactly you plan to clean yourself off. The shower is out of the question as you are too small to work the shower knobs, let alone the force of the spray most likely to be too uncomfortable if not painful. And there is no way you would resort to taking a dip within you toilet bowl. You surmise eventually that the best method if your sink. You can pull the lever on the drainage plug to stop the water from escaping and the knobs on those will be easier for your to operate. It should feel like a nice bath or even a dip in a pool not drenched in chlorine.
At first; you think you most major hurdle is getting up to the sink counter. But thanks to your clawed versatile paws and mini-rodent frame you manage to climb up rather easily. You use the drawers straight edges to get your grip on some of the more difficult parts using the top drawers as a stepping stool to get over the smoother marble surface of the counter in the end. It does wind you a little falling onto your back and taking a much needed reprieve wondering how real mice and rats have the energy to pull these stunts.
Once your strength returns you do exactly as you planned turning on the faucet's hot water and letting it run until the heat kicked in, leaping around to the cold knob and testing the temperature until it is at the preferred heat altogether. You check the sink's bowl briefly to make sure there isn't any left over grime or dust to clean first before you pull up on the drainage plug's lever watching the sink flood close to the top before shutting the flow.
You lean over the pool's surface splashing playfully at the warm waters with your paw. You let the rippling surface grow placid becoming mesmerized at the pool's reflection, seeing yourself in your anthropomorphic mouse form completely for the first time. You caressing your fuzzy cheeks and whiskers seeing the same in your reflection, wiggling your round ears and batting your beady rodent eyes. You bring your paws over your bare naked (though furry) chest gently groping the vestige of your breasts, sneaking a paw down your stomach to tease the animal teats now present under the belly fur.
This is real. This isn't a fantasy or a dream you are experiencing. You have become a real mouse. And the range of emotions stirring from this reality makes it hard for your to decide if you regret it...or love it.
What decision isn't hard is finally diving into the filled sink. It takes you a moment to adjust to how you blow out your air underwater with an animal muzzle sucking in water through your nostrils, gasping for air as you break the surface and wincing in pain. But after some time swimming back and forth, whether doggy paddle or backstroke, diving back underwater becomes easier. Too bad your sink isn't as large or wide as it could be to better swim in.
Eventually; you float to an edge and hang up your arms and relax for a bit, letting your lower half simply drift and float to the top. The temperature is still just right and the only thing that was missing now was some bath soap, candles, and serene mood music. As you continue to hand by the edge you start to wonder how long this rodent affliction might last. Is this going to be a temporary thing or are you stuck like this forever? Will you run the risk of losing yourself again and become a instinctive feral mouse again? Has the mystery rodent already disappeared or could it be watching you even now?
Floating in the warm waters make it difficult to really focus on anything at the moment. For now you just want to indulge in this bit of peace and not worry so much. Whatever fate has in store for you it can wait at least five more minutes right?
