You took a deep breath as you slammed the door shut. It all happened fast, too fast for you to feel comfortable with. And quite frankly, you didn't care too much for this whole situation to begin with. This vacation into Japan was supposed to be short and sweet, and it had gone so well for a while. You rode on a train into a village deep in the countryside to spend the night and explore the area, you heard there were giant salamanders nearby and those are pretty cool. You even had the nicest conversation with this one blonde lady who spoke English. She asked standard questions, like "Where are you from?", "Why did you come to Japan?", and "Do you have anyone that would miss you if you disappeared?" Your standard stuff, it was a pleasant conversation overall.
Shortly after it, she looked around the train. You did too, and you only saw the train conductor looking out to the tracks and an old Japanese grandpa taking his nap. Before you could finish your thought about the old train being so empty, you suddenly found yourself falling downwards, landing into grass.
Internally, you had a momentary Blue Screen of Death as you struggled to rationalize how you ended up from inside the train to outside in some forest. Was this some glitch in the universe? Where was this anyways? It was forested and hilly terrain, and no sign of train tracks anywhere. A blonde-haired girl in a black dress nearby seemed to... float. Odd but maybe that's just a cultural thing in Japan, you wouldn't judge. You approached her to try and ask about your situation, and she smiled. You smiled in return. She seemed cute, in an air-headed way. Her smile and atmosphere caused your common sense to falter, and you decided that she was just so cute, you'd do what anyone else would do - you reached out to pat her head. She thanked you by biting your finger. You recoiled, blood covering your index finger. There didn't seem to be any major damage, but DAMN did that bite hurt and leave a lot of a blood.
When the blonde-haired girl began grinning even wider, blackness swirling around her, you realized that maybe you were in some serious trouble. It was time to bail.
Darting through the woods, you searched for some place to hide. Your pursuer was presumably right behind you, though you dared not confirm that. In some tree rubble? No, too dirty. In the water? You were deathly afraid of mermaids, and you heard rumors drunk ones could turn you into something scary. It was probably untrue, but you wouldn't tempt fate. Eventually, you came across a weird door built into the side of a cliff. It kinda reminded you of a hobbit hole, but only a little. No other options, you prayed the door was unlocked and jumped through it.
And that leads up to now, the present. Sweaty and tired from all the running, you took a few deep breaths to catch your breath. The interior you now found yourself in was... a little queer. The aethetics reminded you of a Western rural house, with decorations that wouldn't be out of place in some grandma's house. The knick-knacks and such adorning the wooden walls and floors, with some out-of-date electronics had a cozy feel to it. Well, cozy aside from the chilly temperature of the place. Realizing that this was someone's home, you called out if anyone was home. You wanted to apologize for the intrusion, after all. The house stayed silent. You debated if you should lock the door. Maybe the owner was out. But if you didn't, that vicious maneater could burst in at any second. After some thought, you reasoned that any homeowner would likely have a key, and that it would be safe to lock.
Stuck in this house for the forseeable future, you saw no other option but to look around. You billowed your shirt to try and cool yourself from the chase of earlier. The inside of the house was cool, but all that running had worked you up a sweat. As you did, small bits of hair fell from your torso, arms and legs, not that you paid it much mind. Your attention was spent elsewhere. Winter photographs decorated the wall. You took your time to appreciate each one, noting the up-close details of snowflakes. The quant living room had a very large recliner, complete with a tv tray and accompanying old tv set across from it. Whoever lived here must've lived alone (and been a loser), you thought to yourself.
Your now-bare legs lead you into the next room of the house, the kitchen. It was also antiquated, charming and cute. As you ruffled through the contents in the pantry, you felt... something... stirring in your nether region. Were you getting horny? Bleh, it must've been the stimulation from the cold... no, hot? Were you cold or were you hot? You swore that it felt kinda cold when you came in here, but you were still sweating just as much as you were outside, if not more. How weird. Weirder still was that the fridge seemed to barely be running. That is to say, its contents were cool and refridgerated, but you didn't hear any electrical hum from it. Weird. It was also filled to the brim with food. Whoever lived here must've enjoyed eating a lot (and been a fattie), you thought to yourself.
Billowing your shirt a yet-again a few more times, you decided you couldn't take this sweat anymore. There was a bathroom in this place, right? Walking down the hallway, you quickly found it and proceeded to take off your clothes. You prayed that the owner of the house would be understanding and wouldn't have the urge to reenact Psycho on you. You looked at yourself in the mirror. You were always a slender person, but you never noticed how your waist seemed to go so inward. It was almost feminine. In fact, your whole physique looked kinda... Maybe you needed to eat more red meats, otherwise you might end up in that trap aesthetic.
You turned on the shower and held out your hand to test the water, waiting for it to get hot. You waited for what seemed like a while, before the temperature finally felt right. You didn't notice any steam, but oh well. As long as it felt comfortable, who cared about steam? Just made it easier to breathe anyways. The refreshing water slid down your body, and you made sure to scrub everywhere, your legs and arms feeling incredibly smooth. The only odd place out was your pubic region. You usually kept the hair the neat and trim, but now it seemed to have grown out a lot. It made your dick look kinda small in comparison. You grabbed your old partner to check its length, when you nearly dropped it from your hand. It was SENSITIVE. Holy fuck, you could feel sparks from that. What was with you, why were you feeling so arroused? You hadn't really masturbated since you had been in Japan, but, was that really it? You looked a bit nervously at the bathroom door. You had locked it, right? You hoped so.
Fuck it, this thing was asking for your attention, and you would oblige. Was it a bit degenerate to do this in someone's private home? Probably, but it was in a shower. Any evidence would wash itself away. You stroked it a few times, positioning yourself against the shower wall. Water poured down down your smooth body, as your bone structure changed even further. Had you been focused on anything but cardinal pleasure, you might've noticed your proportions changing more. Your facial features enhancing their feminine beauty until they became unmistakably female. Your hair changing its length to adopt a fluffy texture with a pale lilac hue. Whatever masculine muscles you had left seemed to fade away, though your thighs grew a bit thicker. Not greatly so, but enough to give you an hourglass figure.
Your shrinking member was getting harder and harder to jerk off, but you paid the fact no mind, too lost in your own lust. Absentmindedly, a hand wandered over to your chest and began to grope it. Nothing happened at first, but slowly, with each rub, the area began to soften and expand. Where once had been a flat, masculine chest developed a nice small set of breasts. They grew in size and in sensitivity, as you tried to contain a moan. They developed into a great and respectable size, giving an equal amount of pleasure likewise. In fact, so much so, that your other hand decided to abandon the penis it was so concerned with earlier to focus just on your newfound breasts. Still desiring to give the last masculine part of yourself some pleasure, you lustfully looked around, desperate for something, until your resorted to just dry-humping the tile wall. The sight would've looked ridiculous to an observer, but you were the only one around, as far as you were concerned.
Finally, release was granted. Your small masculine member gave one final shoot, the last one it ever would, as what was left of your masculinity sprayed itself against the tile wall, and flowed down the drain as water carried it away. Accomplishing its final mission, your penis retreated inward, reforming your genitles to be entirely female. The ability to impregnate replaced with the ability to be impregnated, there was no mistaking it - you were entirely a woman now.
You stood in the shower for a bit longer, mind blank from lust. Once the post-nut clarity sank in, you realized what had happened and turned off the water, rushing towards the mirror. In the reflection was not the good-ol' anon you had seen for years and years. Instead it was a woman, with skin fair like snow, a gentle blush to her cheeks, and soft fluffy hair. She had a mature beauty to her, alongside her large breasts and hourglass shape. The woman in front of you would've been incredibly alluring... If you weren't her, and if you had a penis still.
