Chapter 2.5

Ai was sitting in her room with Syo when all of a sudden she felt something wet between her legs, she looked down and saw blood, she quickly closed her legs and covered herself up. Ai, "Syo-kun" Syo looked up from his book and stared at Ai, "What is it?" Ai, "Can you go get Reiji for me?" Syo, "Why can't you do it Ai-Senpai?" Ai then gave him the scariest look she could conger up, "Don't ask questions, just go!" Syo was scared Ai had never raised his voice. He jumped off his bunk and ran out the room to go get Reiji; not even 5 minutes later Reiji busted into the room with Syo. The look on Ai's face meant that Reiji was the only one who needed to hear this information. Reiji, "Syo-kun can you leave me and Ai-Ai alone for a little bit." Syo, "Sure…" A little part of Syo was jealous of Reiji, but Ai had a look of fear grazing his face. Wait, that couldn't be, he must be imagining things, Ai hardly showed emotions. Syo walked out of the room leaving Reiji and Ai alone. Reiji walked over to Ai, "What's the emergency Ai-Ai?" Ai looked down and grasped her pants, "D-don't laugh." Reiji, "What makes you think I would laugh?" Ai, "Just promise." Reiji, "I promise, I promise, now what's the matter Ai-Ai, you seriously have me worried now." Ai opened her legs revealing all the blood. Ai, "I-I don't know what's going on, it just happened." Reiji instantly knew what was happening, and for obvious reasons Ai didn't, because she hadn't grow up with a mother. It didn't help her case because she was homeschooled until she entered Saotome's Academy. Reiji, "Don't worry, it's nothing bad, this happens to all girls, it's what they call a period." Ai, "Period?" Reiji, "Ah, how to explain this." Reiji felt embarrassed of having to explain it, but he knew he was the only one who could. Reiji, "Once a girl hits a certain age, which can be different for every one, every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn't get fertilized, the lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period. (This is the actual term) The menstrual cycle happens every month and can last from 3-7 days." Ai, "So I have to deal with this every month? How can I hide the fact if I'm a girl if I'm walking around bleeding?" Reiji, "That's why girls have things called pads and tampons that's are used to absorb the bleeding until its over with." Ai, "B-but, I don't have any of those." Reiji, "Go get in the shower, I'll take your sheets change them and put them in the wash and run to the store and grab you some of the heavy duty pads. We'll start you with pads until your get comfortable enough to wear tampons. Also, until you're off your period the best option of clothing would be to wear darker clothes. I'll explain more when I get back, I repeat, do not leave the shower until I get back. Ai nodded and grabbed some dark clothing and went into the shower.

Reiji knocked on the door, "Ai, I'm going to come in and grab your bloody clothes and throw them away since there's no way getting red out of white. I'll buy you a new pair of white jeans while I'm at the store. Ai made sure she was in the shower completely covered before Reiji came in and grabbed the clothes and carried them out along with the sheets, making sure he locked bathroom door when exiting. Ai just sat in a hot shower, watching the blood leave her body. Hoping Reiji would get back soon.

When Reiji exited Ai's room he headed to the laundry room where he ran into Syo. Syo, "Reiji-senpai. What's the matter with Ai-senpai?" Reiji, "Ai hasn't been sick since he was younger, so he didn't have any medicine to help him get better, so I'm going to go to the store and get him some. Until then he's going to take a cold shower to help his temperature down. If you go into room stay out of the shower, and just check to see if he didn't pass out. Syo, "Understood, but why are you carrying Ai's sheet?" Reiji, "Well, he's sick so it would be better to wash them and put him on different sheets until he gets better." Syo, "That makes since." Reiji, "I better hurry, I'll talk to you later." Reiji quickly made his way to the laundry room starting the process to clean Ai's sheets and quickly ran to the store to grab Ai a tone of pads along with a box that was big enough to hold them all, in addition to a lock so nobody else could get into it. Reiji also grabbed some cold medicine to help play with the story that Ai had been sicked. It had been about 30 minutes since he had left Ai in the bathroom and he had to hurry and get back.

Syo walked into the room, and went over to the bathroom door, "Ai-senpai? Are you alright, Reiji-senpai told me you had a fever." Ai, "Y-yeah, I'm fine, Reiji told me to sit in a cold shower until he got back to help drop my temperature." Syo, "If you want I can come in and check your temperature, so you don't have to sit there until he comes back." Ai, "Don't worry, I'm fine, the cool water feels nice on my skin." Syo blushed at that statement. Syo, "Alright, Reiji-senpai, should be back soon." Syo then walked back out of the room. Ai just sat there, "He better."

Ai had been in the shower for about 45 minutes now; this had to be the longest shower she had ever taken in her life. Reiji finally made it back to the dorms and walked into Ai's room after dodging everyone. Once he was in the room he went over to the bathroom and knocked saying that it was him. Ai quickly unlocked the door and then got back in the shower covering her body with a towel. She peaked her head from the curtain, "About time." Reiji, "Okay, I'm going to set up your first pad, then you have to do it from there, and don't worry I'll leave so you can get dressed in privacy. Reiji blushed as he picked up her underwear making sure it wasn't backwards. Reiji, "okay first things first, always wash your hands before and after you put on the pad." Reiji washed his hands then grabbed the pad and opened it up, "Then you grab a pad and open up the package, you take the pad out and remove the long strip of the back, then you put the long sticky side down on your underwear and then if you have wings like the one I have here you take the paper of the wings then put the wings around your underwear like so." Reiji then sighed, "You'll know if you put the pad on backwards and don't worry its an easy fix, just turn it around. You must change the pad at least every 4-6 hours while you are on your period. You'll know when your off your period when you go 24 hours with brown like blood being left in your pad then 24 hours after that it being completely clean. Also when removing the pad, it cannot, I repeat cannot be flushed down the toilet, if you do that you'll stop the toilet up. To throw it away properly you take it and roll it up then wrap it with toilet paper before throwing into the trash can." Ai paid attention to everything Reiji had told her. She nodded and Reiji quickly got out of the restroom so Ai could get dressed. Ai quickly put on the underwear with the pad, it felt weird but she didn't have that wet feeling anymore. She then dried herself off properly before putting on her purple bra with her black tank top with her purple hoodie with black knee shorts. She then dried her hair before putting it in it's normal hairstyle. Once she exited the restroom she saw Reiji sitting down with a box in his hand. Ai, "What's that box for?" Reiji, "This box is holding all of your pads, I figured you wouldn't want the boys to see it, so I figured you could put it in your closet and lock it up. Ai, "Good thinking, I hadn't even thought about that." Reiji, "Figured, here's the combination I set for it." Ai, "Thanks Reiji, really." Reiji, "no problem, also Syo thinks your sick so here's some cold medicine, flush one pill down the toilet to make it look like you took it." Ai nodded and quickly went to the restroom and flushed one pill down the toilet before leaving and taking the box over to her closet and stashing it away. Reiji, "I also got this small little bag that could be locked so you could put a few pads in here just in case we have to go somewhere for a couple of days. This is the lock combination for this one, don't forget." Ai nodded and thanked him again. Reiji, "Also this is Midol, this is what women take if they have cramps right "their" indicating what made the difference when him and her. Ai, "What are cramps?" Reiji laughed awkwardly before explaining, "During you menstrual period, your uterus contracts to help expel it's lining. Hormone-like substance (prostaglandins) involved in pain and inflammation trigger the uterine muscle contractions. Higher levels of prostaglandins are associated with more-severe menstrual cramps." (Actual definition) Ai, "Oh, okay, is their anything else I should look for?" Reiji, "you might crave a certain food, or be more emotional but other then that I don't think so." Ai, "Alright, thanks Reiji." Reiji, "Now get some rest, you look really pale, since this is your first period your body is not used to losing blood so it be best for you to get some rest. I'll either wake you up for dinner or one of your roommates will bring it to you, alright." Ai nodded and climbed into her bed and went to sleep almost immediately. Reiji smiled and left the room, Ai was like his little sister and he was glad that for once he was able to help her, even though, he couldn't have helped her back then.

Ai just had her first period! Like I said in the beginning Reiji is like her embarrassed big brother! Poor Reiji must have been blushing so hard from his embarrassment having to explain everything to her. But what happened to in the past, is it the reason she won't tell anyone other then Reiji about her true sex. Why is Reiji the only one that knows? Find out later on when we get back to the actual story. I hope you enjoyed this chapter and until the next chapter, farewell.
