Should I possess Airi or Chisa?
Possess Chisa
I was conflicted, but I still decided to go for Chisa. If I had to live someone else's life, Chisa seemed like a better person to become than Airi…
I needed a body, even if just a temporary one. I knew she didn't deserve it, but I could always possess someone else in a few days, or try what I thought of doing with Sophie and find a way to share her body with her. Chisa and I didn't interact often before, but she gave me the feeling of someone trustworthy.
I'll have to find a way to talk to her alone before lunch.
The rest of the class went by, and I rushed to find Chisa. Sophie's small frame made it difficult at times to get through the crowd of hungry students on their way to the cafeteria. But I finally saw her leaving her class, and quickly ran towards her.
"Chisa!” I called.
She turned to face me, giving me a warm smile. “Oh, Sophie! Hi!"
"H-hey..." I could feel Sophie's shyness overcome me as I approached her, making it harder for me to speak. "H-how are you?"
"I'm good! Did you want something?"
I fidgeted with my fingers, trying to keep acting like Sophie. "I... I'd like to ask you something... in private."
"Hmm?" She seemed to consider it for a moment. “Alright. You can come with me to the roof?"
"Huh? The roof?"
"It's a great place to... watch the sky and relax..." She answered albeit a bit awkwardly.
That's where she goes during lunch break? No wonder I never noticed her before.
Almost no one went to the roof, so it might be the best opportunity to possess her.
I did my best to fight back Sophie's shyness and smiled. "I'd love to!"
"Great! Let's go then."
I followed her to the stairs, still apprehensive. I tried to convince myself that it was fine. It's just for a few days... I'm not stealing her life forever…
We reached the roof, and Chisa turned to face me before sitting near the center. I quickly glanced around, to make sure that no one else was there. We're alone, good.
I smiled as I walked closer to Chisa. "It seems like a nice place to eat."
Chisa nodded as she started unpacking her lunch. "Yeah. I tend to prefer being alone when I'm eating."
“I see."
"So, what did you want to talk about, Sophie?" Chisa asked.
I took a deep breath. "It's... about Ben."
A teasing smile formed on her face as she leaned closer. "Ben? Did he finally confess his love for you? Or vice-versa?"
I was taken aback, as she seemingly misinterpreted my nervousness. "W-what?"
Chisa chuckled. “Come on, we're not blind, the whole school can clearly see how much you love Ben, and how much he loves you."
“R-really?"
"Of course! It's obvious that you two are made for each other!"
I sighed, somewhat depressed by my own denseness. Was I seriously the only one unaware of this? Trying to regain my composure, I spoke. "W-well... It's... not exactly about that..."
"What is it, then?" Our conversation was halted by Chisa's phone vibrating in her pocket. As soon as she grabbed it, she made a surprised expression. "S-sorry! Gotta reply!" She stood up and walked away, nervous.
Is it a private call?
In any case, it was my chance to leave Sophie's body without Chisa noticing it, as she was too engrossed in her call to look at me. I opened Sophie's mouth and slowly moved towards it. I dropped to the ground, slowly taking shape. When I was fully reformed, I looked at Chisa and Sophie. Sophie was ****, and Chisa was busy talking on the phone.
I slowly went closer, waiting for her to finish her call. "I'll talk to you later, okay? We're still meeting after class, anyway."
Ah, she has something planned for later…
I wanted to talk to Jane afterwards, but it would have to wait, it seemed. Considering what I was about to do, I thought that fulfilling her obligations was the least I could do to repay her.
She hung up and sighed. “Ah..." She turned back, and immediately noticed me, her eyes widening in surprise. "W-what is that?"
I jumped on her and slithered inside her mouth as fast as possible. My body started to dissolve inside hers, and this strange blissfulness returned.
She was trying to mutter something before losing consciousness. "A... sli..."
After a few seconds, I felt my senses coming back. I opened my eyes, feeling vastly different than when I was Sophie or Jane. When I stood up, I noticed how heavy my chest felt compared to Sophie's.
They're... huge… Way bigger than even Jane's…
I already knew that Chisa was fairly well-endowed in that regard, but seeing them from her perspective made them appear massive. So massive that I even felt some back pain.
As I was focused on my new body, Sophie groggily stood up, holding her forehead. "Hmm..."
I quickly went to her side to check on her. "Sophie, are you alright? How are you feeling?"
"C-Chisa?" Her eyes widened as she saw me.
I shook my head. "Not exactly, no. It's me, Ben."
She suddenly jolted up. "B-Ben?! W-why did you possess Chisa?"
"W-well..." I looked away, a bit embarrassed. "I... I saw that you wanted to get closer to her and... decided to possess her..."
Sophie blinked a few times, as if she realised something. "I... remember thinking about you possessing her or Airi..."
“What?"
"I can remember what happened this morning from when we left my room until we arrived in class. But I... see myself doing everything. It's... weird..."
"Hmm..." A theory popped up in my head. "So it seems that whatever happened earlier, it allowed you to remember what I was doing, but as if you did it yourself, is that right?"
“Maybe..." Sophie hesitantly confirmed.
"Do you remember anything else?"
Her eyes suddenly widened again as her cheeks reddened. "W-wait… I... remember... thinking about... being confessed to..."
"H-huh?"
"D-did you... read my memories?"
I looked away and started to blush. "I... I did… I... had no idea about your feelings for me..." I then let out an awkward chuckle. "Even if the rest of the school was apparently aware of that, based on what Chisa told me before I possessed her…” I took a deep breath and smiled. "I love you too, Sophie..."
"Y-you do?" She froze, most likely unable to process that what she heard wasn't a dream.
"Yes. I've... loved you for a long time now. I... I don't know how our relationship could work considering the state I'm in, but would you still be willing to give me a chance?"
Sophie was taking a few seconds to reply, making me more anxious than ever...
It'd be weird, wouldn't it…
But she then gave me a warm smile. "Of course… I love you, Ben, and it won't change no matter what you look like." She approached me and hugged me tightly. "I won't let you face this alone, Ben. I will always be there for you."
I closed my eyes and let out a soft sigh. "Thank you, Sophie..."
She then backed down and looked at me, a bit apprehensive. "Do you... plan to stay as Chisa, though?"
I knew Sophie would ask me this question. "She doesn't deserve to have her life stolen, right? I'm going to stay in her body for a few days at least, to be able to think of what to do next. Maybe I could share her body with her, otherwise..."
She tilted her head. "What do you mean?"
"Well, I'm not sure it's something I can really do, but I thought of trying it back when I was still possessing you. I thought that I could maybe let my host be in control while still being in their bodies."
She smiled. "I see. I'm... glad you're thinking like this."
"Oh yeah, before I forget, let me give you Chisa's number!"
"Sure!"
When I grabbed her phone, I noticed what time it was. "We should quickly finish eating before lunch break ends, though. We can talk more later."
"R-right..."
We both sat down and started to eat. Chisa had a salad with tomatoes, lettuce, mushrooms, rice, and tuna that looked homecooked. And looking at her memories confirmed my thoughts.
"Hmm, Chisa is a pretty good cook."
Sophie eyed my tupperware with curiosity. "Can I try?"
I chuckled. "Getting more daring, now, hmm? Would you have asked that to the real Chisa?"
Fidgeting with her fingers, she shook her head. "N-no..."
"You're so cute!" I didn't know if it was because Chisa's personality was starting to influence me, but I really loved to see Sophie so shy, way more than I did before.
"S-stop it... Hearing you say this with her voice is so strange..."
I grinned at her. "It's hard to resist."
After a moment to regain her calm, Sophie spoke again. "So... how's it like to be a girl? To be Chisa?"
"Hmm… It's interesting, I'd say. Being a girl feels very different, even if I fairly quickly became comfortable as you." I admitted a bit shyly.
"Is it why your two potential hosts were girls?"
"Y-yeah... I was... curious..."
Sophie giggled. "Oh, are you ashamed? I don't think there's anything to be ashamed of, it's normal to be curious of what being the opposite gender is like. And I imagine that being Chisa must feel different than being me, as well. Isn't it?"
I couldn't help but glance down, as there were two major differences between Sophie and Chisa. "It... does..."
It only made Sophie laugh even more. "Hehe, I can't believe you have a bigger chest than me, right now..." My embarrassment was apparently a source of amusement to her. "I'm going to be jealous..."
"Y-you don't have to! Y-you're perfect the way you are!" I hastily replied to reassure her.
She smiled at me. "Thank you. And thanks for not telling Jane this morning."
"I was tempted, but I decided that it'd be better to tell her everything with you by my side."
"Will you come home with me after school?" She asked.
I shook my head. "Chisa apparently already had something planned, and I don't want to mess up with her life.I'll come by afterwards, though."
"Alright. I'll think of how to explain things to Jane meanwhile, then. Text me when you're done."
I nodded. "I will."
What's next?
