None!

"And what's that?" I asked.

"That once you enter this hot spring there's no going back. You'll never be able to enjoy any other hot spring again. Nothing will compare to the perfection of the purity hot spring! Now go ahead you two. Go and have fun. Just make sure to wash up first before you get in." He said with a chuckle.

I let out a breath of a relief. At first, I thought he was going to mention one of the criteria's or strange rules for the hot spring. We definitely got lucky with the school renting out the entire place. We don't need to go through any security or anything to enjoy the warm, relaxing water.

Quickly we both headed through the curtains and into the changing room. Unlike our school, there wasn't any lockers. It was just wooden shelves with baskets. Even in the changing rooms, they still had the same aesthetic as the rest of the building. We undid our kimonos, sliding them off our bodies, folding it, and leaving it in one of the baskets.

"Oooh~ Looking good as always." My friend laughed.

"Shut up. You just saw me changing back in our room."

"You know, we should invite that staff member to come here with us later. I'd love to put you two side by side and whose breasts are bigger. My money's on hers. Though these are still my favorite~" She said as she walked up behind me and started groping my breasts from behind. Her thumbs and index fingers finding their way to my nipples. Pulling and twisting them.

"S-Stop that~" I muttered as a moan escaped my lips. "L-Look at the other baskets on the shelves. T-There's probably another girl in here, I don't want them catching us like this."

"Fine, but you owe me~" She sang before giving my butt a light tap and walking away.

We headed towards the showers. These were different from our school too. We weren't standing up with curtains or stalls between us. We were sitting down, the shower head in our hands as we lathered our bodies in soap. It was a bit of an annoying tradition. You had to wash up here so you wouldn't get the hot springs dirty. It made sense, it meant the hot springs wouldn't ever get dirty. It was still annoying though.

I quickly washed up, not wanting to take too long and give my friend the opportunity to use the shower head for more than just washing...Or to offer to help wash my body. Luckily, I managed to finish washing up before she did. I waited another minute or two as she cleaned her hair before we finally headed off.

We didn't see any towels anywhere, and we were going to get into the water anyways, so we just walked forward with our bodies completely exposed. Depending on how the other girls are, we might make some conversations and some new friends. Though if it seemed like they wanted to be left alone, we'd just stick to a corner and talk to each other while enjoying the hot spring.

As soon as we sat down the edge of the hot spring and dipped our feet inside, I realized our mistake. We really should've checked the clothes inside the basket... There were five guys there, watching us. Staring directly at our breasts and pussy. One of them, I could've swore was our teacher.

My entire body instantly turned red. My body felt like it was on fire, like my heart was going to burst out of my chest. I jumped up, ready to run back to the changing room.
