Kasumi gets her room key.

Kasumi watched as her fellow classmates received the same flower necklace until she heard her name called out. Kasumi looked over and saw Kawakami walking towards her with what seemed to be her room key. "Kasumi," Ms. Kawakami called, waving her over. "Here’s your room key. You’re in 304 on the third floor. Go ahead and unpack." Kasumi took the key and started heading towards the elevator; she walked in and pressed the third-floor button. As she rode up, she imagined what her room would look like. Would there be a view of the ocean? How big will it be? The elevator doors opened, and she stepped out into a bright hallway adorned with tropical artwork. Kasumi found her room and unlocked the door.

The room was a lavish and quite massive just for one person. A balcony overlooked the shimmering ocean. Kasumi dropped her suitcase and rushed outside. The salty breeze rushed through her hair as she gazed at the horizon. She could see surfers riding the waves and all the people lying on the beach. Kasumi turned back around and started unpacking all of her belongings. She took out her recently brand-new bikini, which was a bright pink two-piece that had a nice fluffy design to it. As Kasumi examined the bikini, she did feel a little nervous about wearing it out in public since it didn't leave too much to the imagination and looked a little bit too small on her, but Kasumi pushed those thoughts away and kept unpacking the rest of her clothes.

Eventually Kasumi finished getting unpacked and sat down on the bed and felt a wave of sleepiness wash over her. As she was about to lay her head down, she suddenly heard a knock on her door. Kasumi stood up and walked over and opened the door to see some of her female classmates standing in front of her, all wearing different types of bikinis. Some were wearing a standard plain color, and others were wearing just an ordinary one-piece, and then there were a few who were wearing such small bikinis that it looked like they weren't even wearing anything. Kasumi was surprised that those girls were even allowed to wear those on the school trip. The girl who knocked on her door spoke up, asking if Kasumi wanted to go and head on down to the beach with them. Kasumi immediately accepted since the beach was the part she was looking forward to the most. The girl told Kasumi that they would meet her in the lobby. Kasumi quickly ran over to the bed where her pink bikini was and grabbed it, heading towards the bathroom to go get changed.

Kasumi quickly started stripping off her clothes, starting with her school blazer and shirt. She folded them and placed them on the countertop. Moving on to taking her skirt off, she pushed it down and stepped out of it. Kasumi then peeled off her leggings and set them with the rest of her clothes. Kasumi now stood in only her underwear, which she quickly undid her bra and felt it fall off, revealing her bare breasts to the open. Now that Kasumi was fully naked, she took the bikini top and tried it around her neck, making sure it properly covered her chest; she did the same with the bottoms until she was now ready to head down to the lobby to meet up with her classmates, but before that, Kasumi glanced into the mirror to look at herself. She looked at how her pink bikini made her curves stand out and how it clung to her body, especially around her hips and chest. Kasumi was a little worried it might be a little too much and might bring too much attention on her, but then she remembered what some of the other girls were wearing and figured that she should be alright.

Kasumi walked out of the bathroom and grabbed the towel she brought and wrapped it around herself. Kasumi knew the other girls didn't really care about walking around half naked, but she felt a little uncomfortable with the idea of walking around with so much exposed skin. One final check to make sure she has everything she needs, Kasumi exits her room, making sure to lock the door behind her. She walks down the long corridor until she makes it to the elevator; she waits for the elevator doors to open, and as they do, she steps in and presses the lobby button. After a short while, she is now in the lobby; she looks around for her classmates. It doesn't take long for Kasumi to spot them: a group of around five girls all wearing bikinis stood near the exit of the hotel. The girls all waved towards Kasumi to signal her to come over; Kasumi walked towards them, ready to head down to the beach.
