Author's note: I am including reference people for the main characters appearances. If you are interested you can look up photos to go along with the story: Alyssa - Irelynn Dunham, Hanako - Yui Uehara, Aika - Miki Hamano, Sayo - Ruri Tachibana. Or you can use your imagination.
On the way back down Alyssa was feeling self conscious but energized by her mountaintop exhibitionism. Aika and Hana had their kimonos back on even more loosely than before as they bounced down the path. They told Alyssa that it was time to go to the main onsen bathing areas.
There were still few people at the building as they returned. Alyssa looked at the place in a new light now knowing it was for women only. The big gate made more sense and the complex felt more open inside. They passed a few employees including Sayo, who gave her another deep bow and long stare. While everyone she saw by the doorway and in the hallway was covered, mostly by robes, she had the feeling that clothes were unnecessary -- that at any moment they could all be naked.
In the anteroom to the bath there was a washroom, as it was customary and indeed mandatory to clean oneself before entering. These rooms are open, with half-length stalls and no privacy. Despite the different setting, the girls washed each other as they did at home. The lone other women in the wash area appeared to pay them no attention as she scrubbed her crotch in full view.
The pool was large and stretched outdoors with 3 small side tubs. Beyond them were trees which hid a wall at some distance, giving if the feel of being in the woods. A couple women middle aged women sat together in a tub under a waterfall dumping a cascade of steaming water on both of them. Another pair were walking around. The onsen in town had been modern, clean, and comfortable, but this one was luxurious with aged wood and stone that seemed to be a part of the landscape itself. It managed to be even more peaceful and soothing. If she felt exposed to nature nude on the mountain, she felt at one with it here. Her excitement was no longer nervous or self-conscious.
Here the patrons made little attempt to cover crotches or breasts with tiny cloths or their hands. The bathers' comfort with their nudity bordered on exhibitionism and struck Alyssa as very sexy. The women were fit and shapely with smooth skin and hairy bushes.
After Alyssa gazed at the activities going on around her for some time, Aika broke her trance by tugging her hand. She gestured to the smaller pools to the side. These had pipes above which created a waterfall a couple feet wide. They stood together in front of it in the pool. Aika pulled the other 2 girls in so they could all feel the smooth pressure of the water coming down at once. She maneuvered them into a triangle so that their bodies were all pressed together with water flowing in the middle. The downpour mixed with the rubbing of body parts against each other leaving Alyssa turned on again.
When they sat back down and the rest of the scene returned to her view, Alyssa noticed several of the women watching them. Shortly after, as she followed Hana and Aika out, she could feel the eyes of the others checking her out from head to toe.
They walked through the hallways with kimonos carelessly closed not even tied as if the place was theirs, making brief, silent exchanges with those they passed. They returned to their room totally relaxed and tired from the heat and the day's adventures. The staff had laid out futons on the tatami floors for the girls to sleep though there were only 2 -- 1 large and 1 small.
The small futon was for Alyssa. She barely had the energy to pull on her panties and tshirt for sleep. Aika and Hana had relinquished their kimonos as then entered the room without putting anything else on. They said, "oyasuminasai" (good night) and bowed in unison, then crawled into their futon together and whispered as they held each other close.
Alyssa watched their silhouettes in the low light as they remained with their heads close. She was no longer fazed by their touching but did not expect them to sleep nude together. She as her mind wandered to thoughts of being between them she dozed off.
The girls were reading in chairs by the window when Alyssa awoke. They had their robes open as they sat back, languidly turning pages. Somehow they either guessed when she'd be up or alerted staff when she had, because the breakfast seemed to show up almost immediately, carried by 3 petite attendants. Hana greeted them without attempting to close her robe. Aika was probably more exposed as she pointed out the desired locations of the settings and gave some other instructions.
Once they were gone Alyssa took her shirt off and looked for her kimono, only to see the other two drop theirs again. "I guess I need to expect this," she thought as she sat down in only her panties for an otherwise traditional Japanese breakfast. The girls told her about a longer hike they would do in the late morning that was even more beautiful than the one they had done the prior day. After eating they picked up a bag and gestured towards the door.
This trail started out steeper. Alyssa was pleased that she put on her sports bra and panties. After some time the trail leveled out and they passed another pair of hikers also in loose kimonos. Hana seemed to know them as they briefly conversed in rapid, chipper Japanese. She tells Alyssa that from there they can go as they'd like. The 2 Japanese girls remove their kimonos, and invite Alyssa to join them. She gave up her kimono, but kept the underwear.
She got to watch their nude bodies as they move gleefully through the forest. Hanako's thin frame glided elegantly with a little bounce in her small breasts. Aika had a more sensuous motion with her hips turning and her tits jumping. Alyssa imagined they had a floral scent she can smell and follow. She felt her lust bubbling up. For the next several minutes she debated if she would strip. She definitely wanted to, but needed to build up the courage for just a moment. "If not now, then when," she said, convincing herself.
