Chapter 10

Wednesday - Morning April 22nd

Mmmm ... Saeki's right breast filled my hand, so wonderfully firm, yet amazingly pliant. Her nipple had grown ripe as I caught it between my fingers. I pinched it between my knuckles, refusing to release my urgent grip. I loved her tits and I'd been dreaming of them. Perhaps I still was, but no. I kissed her neck and hair, opening my mouth as if I might bite her, but all I did was suckle gently and tease her with my tongue and teeth.

"Uh-hmmm..." she sighed, sleepily, contentedly as she lifted her top leg, the right one.

My cock had grown through the open fly of my boxers and the pulsing shaft rode along her pussy. We were moving together, slowly at first, but with increasing energy as we came more fully awake. She still wore her panties. I couldn't get inside the girl, but I felt her heat radiating from between her spread thighs. Saeki lifted her head, wanting a kiss, I thought. I couldn't see her, because I wanted to keep my eyes closed and explore her by touch and taste. It didn't matter -- I had memorized every part of her.

"Oh my God!"

"Huh?" I opened my eyes and screamed. "Aiiiii ... Yukiko!"

"You dirty pervert! Get away from me!" She shouted, slapping my hand away from her tits. She clamped her legs together, briefly trapping my erection against her pussy.

"What are you doing here?" I yelled, blinking my eyes as she twisted her body, rolling over and quickly sitting up.

Her top, the ragged t-shirt, had been pulled upward and Yukiko's luscious breasts jutted proudly from her chest. I couldn't help but stare at them, noting how plump her nipples had become after being gently pinched and pulled in our sleep. They much resembled my cock that way, which was exactly where her attention was fixed. I sported a long, fat erection that bobbed sharply every few seconds with eager desire. Never mind the shock and horror I felt at cuddling with her, my cock had plainly enjoyed every second of it!

"You'd rape your own sister?" She shoved me off the bed with a painful THUD! when my skull bounced off the floor. "You sneaky jerk! I should castrate you!"

"But ... What happened to Saeki?" I rubbed my head as my sister ran from my room. It took me a few seconds to actually believe that I'd only been dreaming. She'd seemed so real.

Sunrise must have been another hour or two away. Through my window, the sky was still dark without even a hint of morning.

"Five in the morning?" I frowned at my clock and crawled back into bed.

Now that the excitement was over, I hoped that it wouldn't take me long to fall asleep again. My cock refused to soften, however, and I could smell Yukiko on my bedding. The mattress was still warm where she'd been laying. I tried to turn my thoughts back to Saeki, but as I squeezed my erection, she kept turning into my sister.

Instead of sliding my swollen erection into Saeki's moist pussy, in my imagination it was Yukiko pulling me inside. Her tits rubbed my chest. Her stiff nipples inviting my mouth to suckle them while we made love. She wrapped her legs around my hips, pulling me deeper. I felt her fingers scratching my back, urging me to fuck her faster and harder. We were going to cum together!

"Fuck!" I let go of my cock as if it had burned me.

I'd been jerking off, but I hadn't cum. I didn't want to! Masturbating to obscene visions of fucking my own sister? I felt almost sick to my stomach. Humping her in my sleep was one thing, like accidental, but this was something else completely. I blamed her for it. Stupid Yukiko and her teasing. What did she expect? She walked around the house wearing next to nothing, sharing every dirty detail of her sex life, and trying to make me spill in my pants for her amusement.

She's lucky I didn't rape her! A man can only take so much, after all, and a little bit of gorgeous, sexy Yukiko went a long way. Sleep would be impossible now. I needed a cold shower. Imari would be coming around at seven to wake me up anyway and while I'd normally leap at the chance to get even a few more minutes of sleep, I was more interested in deciphering my black book.

The heavy tome sat on my desk, calling me like a siren to explore its mysteries. Yukiko had translated quite a bit the night before, but so much more remained. We hadn't even gotten to the really complicated spells yet. Yeah, I decided, a cold shower, some breakfast, and a good hour alone with my notes sounded better than laying in bed with a boner.

"Uh-huh! Oh! Little brother ... Yes! Fuck me!"

I stopped short, blinking at the closed door of my sister's bedroom.

"Your cock is so big," she groaned. "Be careful with me, I'm a virgin! Oh! Like that! I love it when you touch me there!"

The sound of her bed shifting on its old springs lent a curious melody to Yukiko's breathless narration. I didn't have to see her to know that my sister was masturbating.

"My little brother's cock is in my pussy!" she gasped. "Fucking me! Fuck ... ing ... me!"

Obviously, Yukiko had no issues with her incestuous fantasies! What surprised me, as stupid as it sounds, wasn't that my sister would play with herself. I just couldn't believe she actually got off on the idea of having sex with me. I'd always thought she'd been teasing me, torturing me with her body and lewd innuendo. My sister really did want to fuck me? So why had she run away?

She needed a doctor!

Perhaps I did as well, considering the way my cock had instantly grown hard as steel beneath my towel. I'd been on my way to the bathroom, but instead, I turned the handle of Yukiko's door as cautiously as possible. She probably wouldn't have noticed if I'd kicked it down, but I didn't trust her either. This could be just a ruse to torment me further, especially as she wasn't even trying to be quiet.

"Uh-huh! Uhhhh ... God! I'm going to cum! Make me cum all over your big cock!"

I peeked around the barely open door and felt the bottom fall out of my stomach. This wasn't another of my sister's tricks! She was on her knees, ass high in the air with her shoulders on the mattress. I had a perfect view of her tight, round ass, and especially her dripping wet pussy as Yukiko rubbed her vulva with wanton delight.

"So good!" she gasped. "Bite my nipples, little brother! Fuck my cunt! I want to feel your cum inside me!"

My cock jerked beneath my towel, already leaking clear precum, and I had no choice but to rub myself through the rough cotton. Yukiko's eyes were tightly shut, her panting voice loud and clear as she filled the bedroom with obscenities. She didn't finger her pussy at all, I noticed, but kept moving them around in a tight, frantic circle. She'd pull her rubbery labia one way and then the other, bucking her hips every time she crossed over her distended clitoris.

Juices streamed down her spread thighs, a thin, whitish discharge that reminded me of Mika Ito. Lubricant for a stiff cock, I told myself, that's what it was. Yukiko's flushed body shivered as she grabbed her right breast, digging her fingers into the tender flesh and pretending they were mine.

"Yes! Love my tits! Squeeze the milk out of them! Fuck your milk into my pussy! I love you!"

And with that, my sister's orgasm arrived with a spurting flood of female ejaculate! The oily juice squirted between her fingers, spattering like rain between her legs. Yukiko spread her pussy lips apart, showing me the bright pink flower of her sex.

I had my fist wrapped around my cock, having loosened the towel so it could lay at my feet. I stroked my erection, lost in the unexpected and brutal display of my sister's sexuality. Everything that had come before, all those years of merciless teasing, paled by comparison to the awful truth...

"You made me cum, little brother," she whispered, staring with her bright, brown eyes wide open and fixed on mine.

A smile played at her lips as she massaged her drooling cunt and I froze with my cock pointed right at her.

"Ugh!" I hitched a sharp breath and threw my hips forward, pulling back on the shaft with the first violent spasm of my climax.

Semen flew through the open door to land on her bedroom floor. I squeezed the base of my cock as if I might choke the remainder off, but it was too late for that. Hot ball cream burst from my cock with reckless abandon. Six or seven deep contractions pulled the sperm from my balls and sent it flying towards my pink-faced sister.

She didn't move from her bed, but kept rubbing her pussy, pulling it open with both hands between her drenched thighs. She was giving me a target, or so I imagined, but my cum landed far short of her bed. It didn't matter. As soon as I'd finished cumming, even before the weakest pulsations stopped completely, I felt the unwelcome taste of guilt rising in the back of my throat. We'd just had sex, Yukiko and me, and even if we hadn't touched each other physically, I'd felt another, much more personal connection. We'd shared something taboo and foreign to my conscience ... I'd fucked my own sister!

I pulled the door shut, almost slamming it in my haste, but I was terrified that she would say something to stop me. What if Yukiko invited me into her room and onto her bed, would I say no? I couldn't have feelings like that for her, but she obviously felt something more than sisterly affection for me. This was wrong! It was just a game to her. She'd acted outraged in my bedroom, only to fantasize about me in hers. She'd wanted me to catch her doing it too, of that I had no doubts. Yukiko had planned the whole thing. She was seducing me, slowly but surely, and I couldn't stop her.

My penis hadn't even gone soft. I wanted to turn around and go back, throw open her bedroom door and bury my cock inside Yukiko's pussy. That would finish it, I thought, once and for all. There would be nothing left after the ultimate betrayal of our family honor. We'd be damned for all time, but free of guilt and shame. That would be Saeki's argument, and I could hear the girl's lilting voice urging me on.

"Obey your instincts and leave morality to the sheep," she said, smiling. "It's only wrong because someone else wants it to be. Go ahead, Minase. Fuck your sister and loose the demons from their chains ... and then you can fuck me."

I shook my head, nearly falling down as I wave of dizziness washed over me. She's been there! Saeki. I'd seen her and heard her voice, but not in the bathroom. I looked around, trying to remember the way people do with dreams, forgetting the details in that split-second between sleep and waking. But it felt like deja vu, not a dream at all. Had she said something like that before? No, I didn't think so, but her voice had been so clear. The smile on her face and the humor in her lavender eyes. All of it seemed so familiar, and I was lucky that way -- Saeki made me forget about Yukiko for the moment, and an ice cold shower did the rest.

"Minase?" Imari rubbed her eyes. "I can't believe this! You're awake!"

"Did you see Yukiko out there?" I asked, ignoring her theatrics. She'd just walked through the front door like she did every morning.

"I must be dreaming!"

"Don't make such a big deal out of it," I told her. "Did you see my sister or not?"

"Yukiko?" Imari shrugged. "I saw her outside, walking towards the train station. Why?"

"Nothing," I said, going back to my notes.

After my shower, I'd stayed in my room, grateful that my sister hadn't decided to bother me. She probably didn't have time, since she was supposed to be at work by the time Imari showed up. I'd eaten a muffin for breakfast, barely tasting it as I compared the translated spells to the originals. I definitely didn't want to depend on Yukiko for any more help!

"You're studying, too?" Imari asked, looking genuinely astonished. "What's come over you this morning?"

"Hey! For your information, I study a lot," I protested. "Just because you've never noticed before..."

"I would have noticed something as strange as that!" she exclaimed. "What's this book? Encyclopedia of Demonology? Witchcraft? Where did you get this?"

"Saeki let me borrow it," I answered, turning in my chair. "Give me that."

Imari frowned as I took the book out of her hands. I closed my notebook and the Bible Black as well, stuffing them inside my book bag. There wasn't enough room for the encyclopedia, so I'd just have to leave it a home. I wasn't in a real hurry to give it up just yet anyway. I still had a lot to learn.

"So you like magic now?" Imari asked. "Or is it just her?"

"I don't know," I sighed. "It's complicated."

"She's very sophisticated, isn't she?"

"Saeki?" I couldn't help but smile. "Yeah. I guess so. She's different."

"From me?" Imari looked decidedly unhappy.

"Well, of course," I said. "There's nobody else in the world like you."

Her irrepressible smile returned with a vengeance. "Really?" she asked. "You're not just saying that, right?"

"Of course not," I insisted. "You're the only girl I know who can be annoying and fun at the same time."

"Annoying?" She narrowed her eyes.

"And fun," I repeated. "You're one in a million, Imari."

"Now I know you're teasing me!"

WHAP!

"Ouch! Jeeze! What did you hit me for?" I asked, rubbing my shoulder.

"Because you deserve it," she replied. "Hurry up and get ready. You have to buy me a bean cake now."

"You just wanted to kiss me," I told her. "Didn't you?"

"Excuse me?" Imari's cheeks turned pink.

"That's why you hit me all the time, isn't it?"

"No!" she protested. "Where did you get that crazy idea?"

I wondered what I was doing. Seriously, I asked myself why I'd ever want to venture into the minefield of romance with my oldest and best friend. Maybe because I had feelings for Yukiko? I didn't even want to look in that pocket! Something had happened that morning, but I'd pushed all thoughts of my sister away. I had to resist any desire to explore such a perverse relationship as incest.

But Imari was like my sister too, wasn't she? I felt the same discomfort when I considered Imari sexually that I did with Yukiko. There was one significant difference between them, however ... I could have sex with Imari and be guilty of nothing more than taking our friendship to the next level. Falling in love with her would be normal, even expected by everyone who knew us. Maybe I'd had the perfect girl all along and just didn't know it.

Or maybe I wanted to fuck Yukiko and Imari would be the perfect stunt double. It would be like incest, but not incest. Shoot, I felt ashamed of myself just for thinking about seeing Imari naked, which was the whole point. Fucking her would feel exactly like fucking Yukiko, except I couldn't get in trouble for it. Why did I want to feel guilty though? There had to be something wrong with me, but I couldn't shake my excitement.

"Why are you looking at me like that?" she wondered. "Are you feeling okay?"

"Huh?" I blinked at her. "Sorry. I was, um ... I didn't get much sleep last night."

"Well, I'm not going to kiss you," Imari said. "So you can forget about that!"

"Okay."

"Okay?"

"Uhhh..." I smiled a her. "It's not okay?"

"I don't even know what we're talking about anymore," she sighed. "Buy me a bean cake."

I did exactly that, but Imari's reaction hadn't been anything like I might have expected. She seemed almost embarrassed when I suggested she wanted to kiss me. Why had I imagined anything else? It's how I would have responded to such a strange idea. The girl wasn't going to suddenly leap into my arms. Imari probably didn't even like me that way. I wasn't even sure if I liked her that way! Neither of us wanted to ruin our friendship, I knew that, so of course we couldn't kiss.

Just like I couldn't possibly kiss Yukiko? Definitely. But still, the idea had been planted and as we walked to school, I couldn't help but appreciate Imari in a whole new light. She might have been thin, hardly voluptuous like my sister, but in a firm, athletic sort of way. If her tits were on the small side, they were definitely perky beneath her blouse. Imari wore a bra, of course, but it didn't hide the wonderfully upturned shape of her breasts.

She had long, coltish legs toned from years of martial arts practice. I'd always thought them skinny, but that's because I remembered how awkward Imari had been as a girl just entering puberty. Our friendship made it almost impossible to look at her with any sort of objectivity. My memories were so strong and clear. I'd never been able to separate my past feelings from the present, but now I could finally see the beautiful, sexy young woman Imari had become.

For the first time in my life, just looking at her made my cock stiffen with desire. Man, I thought, this was getting complicated!

Arriving at school, the first thing I did was check Ito's shoe shelf. After masturbating in front of the entire class, I didn't honestly expect her to return the very next day. I breathed a silent sigh of relief when I saw her school shoes undisturbed. She hadn't come back, but Imari and I had gotten there even earlier than usual, so it was possible Ito could still show up. I really hoped not. I didn't want to be confronted with the fact that I'd not only cast a spell on the girl, but I'd raped her as well.

"I guess Mika isn't here today," Imari sighed. "I hope she's going to be okay."

"Yeah, me too," I agreed, with somewhat mixed feelings.

We changed our shoes under an oppressive silence. It was like the girl had died or something, which seemed pretty ridiculous. I half expected to see Ito's ghost reaching for her shoes and I wrote off my apprehension as guilt. She'd been humiliated, that's all, I told myself. She'd get over it.

"Did you bring my book?" Saeki asked, already in our classroom and playing with her Tarot cards.

"I'm still using it," I said. "I hope you don't mind."
