Isamu's moons! (Patreon)

"Ugh... I can't believe Isamu wanted to come here. I could have slept in." Aika grumbled as she walked behind Isamu to the local planetarium. She wasn't the biggest fan of museums of any kind, but Isamu had insisted they go early in the morning. "Why do you want to come here anyway? Don't you have anything better to do on the weekends?"

"I haven't been to one! Besides, I got these early bird tickets for cheap! Stop being so grumpy, you might actually learn something!" Isamu curtly replied. This annoyed Aika, souring her mood just a bit more.

Isamu was mesmerized by the exhibits in a dimly lit room, illuminated by spotlights. "Wow! It's like we're really in space! Isn't this nice?"

"Yeah, yeah..." Aika looked disinterestedly at the models of planets and moons. Suddenly, a plan had appeared in Aika's head. "Hey! There's an astronaut ride over there! You should get dressed for it, go to the bathrooms and strip down in a stall, I'll go collect the suit!" Isamu, giddy with excitement, immediately darted to the bathrooms without a moment's hesitation. Aika smirked and waited a few minutes before following her in.

"Which one are you in, Isamu?" Aika called out to her. "The one at the end! I'm ready to put the suit on!" Aika stifled a laugh. "Alright! Now they said you need to take off your underwear too, hand me your clothes and I'll give you the suit! Isamu happily stripped down and handed a pile of folded clothes to Aika under the door of the cubicle. "Alright! Now hand me the suit!" The faint sounds of footsteps could be heard going away from Isamu.

"...Aika?" Isamu cracked the door open, only greeted by an empty bathroom. "Huh... Maybe she's outside? Hopefully the place is still empty..." Isamu slowly walked out of the bathroom and back into the halls, completely exposed.

"Still safe! I can look for Aika without worrying too much." She walked around searching, but to no avail. She soon got distracted, as there was something magical about the experience of being completely nude, passing by the planets and stars. Isamu felt oddly at peace.

That peace was soon shattered though, as the sounds of a crowd could be heard entering from around the corner. Isamu immediately attempted to look for a hiding spot, but there were no good ones. Returning to the bathroom she came from would been going towards the sounds of the crowd. The crowd would soon be able to see her. In a panic, she stepped behind the largest exhibit she could find, a model of the Moon.

She could see the silhouettes of the crowd, but didn't seem to immediately take notice of her. "Huh... Maybe it's too dark to see me clearly? She relaxed a bit and got up slowly from behind the model, still instinctively covering her crotch. "I should take the opportunity to go further in to find Aika-EEP!"

The floor below her rotated, her rear now facing the crowd. A bright light meant to illuminate the model of the moon instead shone on Isamu's large behind! The crowd definitely noticed as now flashes from cameras began going off, as well as the increased murmuring.

"That exhibit looks a lot nicer than I remember!"

"I didn't know we had two moons!"

Isamu's face turned bright red hearing the comments, but she also heard the cackling of a familiar voice. She immediately ran towards the sound of the laughter, finding Aika laughing uncontrollably. "Give me back my clothes!"

Aika calmed down and handed Isamu her clothes back. "You know what, I did learn something new! I'm a big fan of your "moon" walk!" Isamu sighed at the joke as she quickly found a corner to get dressed.
