Tomoe was a part of our family as far back as I could remember. When she was a Kirlia and I was a baby, she could always sense when I was about to cry and would have just the thing to cheer me up—whether that was a blanket or my favorite toy. She so impressed my parents that they basically made her my babysitter as we got older. "Big sis," I would call her, especially when she became a Gardevoir. Even though we were only a few years apart, she truly looked the part of the older sister, towering over me in my preteen years.
Maybe it's how empathetic Tomoe's evolutionary line is, but we always had a close connection. I was always a little terror, and she was always the calming, angelic presence. I think for a while there I even liked teasing her just to see how far I could push that patience—deliberately leaving messes in my room or coming home with muddy clothes just to see if she'd silently puff her cheeks out in mock annoyance or wag one of her three small fingers at me reprovingly. But her patience must have won out. The loving headpats when I did my chores, and the many late nights talking while she listened silently and attentively, me all cuddled up in her arms, winning out in the end and maybe transferring some of that mellowness to me.
But in my late teens, that childish rebelliousness gradually turned into...something else. When I looked at big sis, my heart started to ache. I felt restless cuddling with her at night. For the first time, I had to ask her to sleep separately from me (the guest bedroom was technically hers, but she never used it). I didn't even want to take baths with her anymore, and that had been one of my favorite things growing up—watching her levitate soap, brushes, and even water made it a show every time.
Now I was lying awake in bed, alone, thinking ruefully about just that. All the fun I was missing out on because the thought of feeling her against the bare skin of my back, her soft and warm chest horn against my back, her arms casually wrapped around me as we both relaxed was doing decidedly unrelaxing things to me. It was making me itchy and nervous, and a spot in my pants was getting quite lively.
School had covered it, but I never really paid attention. Guys in class had talked about jacking off, but I hadn't really felt the urge until now. Call me a late bloomer, but now that I'd caught up at eighteen years, I kinda hated myself for it. My own body was getting in the way of all the closeness I'd had with big sis Tomoe. And I couldn't stop it—even now, it was making my heart race just thinking about her.
As I was struggling with those thoughts, I heard a very gentle knock at the door. I could feel the faint telepathic connection—it was Tomoe. I scrambled to throw some covers over myself to hide my excited little buddy down there and called her in.
"H-hey there-whatcha need, sis?" I asked.
She glided gracefully around the bed and sidled up next to where I was sitting at the edge of my side of the bed, rather than the opposite side. A bit too close for comfort, considering the state I was already in.
"Uhh, you really shouldn't—we probably shouldn't cuddle like this anymore, it's—ah..." Arceus, this was awkward.
She must have sensed my awkwardness, because she started stroking my head comfortingly, pulling me closer in. But that only made things worse down below—she smelled so sweet, so unlike any human. She radiated a feeling of understanding, and I realized my awkwardness wasn't the only thing she'd caught on to with her telepathy.
"If you know what's going on with me right now, you should leave me alone, Tomoe...I don't wanna creep you out."
Tomoe shook her head. She hugged me tighter—a lot more firmly than the casual, sisterly hugs we used to share.
