Shinji is woken up by a cold breeze...

Why did it get drafty all of a sudden? I opened my eyes, expecting to find the covers stolen by Kouki rolling away from me in her sleep, but instead found myself alone in the bare bed. Confused and chilly I looked up to see some commotion going on around me, but I couldn’t focus, fuzzy from being fast asleep, and it was still pretty dark as well. I yawned and curled one hand over my eyes as I tried to rub away the tiredness to see what exactly was happening.

"Let me go!" Kouki screeched as she tussled with someone.

"What's wrong, sis? Given the way you were moaning earlier I figured you'd like getting manhandled," her familiar-sounding male assailant mocked.

"Kenji?" she asked sounding scared and confused and my mind agreed it sounded like Kenji, but not entirely the same either. Something was wrong with his voice.

"What’s go’in…" I started before involuntarily interrupting myself with a yawn. "...on?"

<Shinji, my sweet. You’ve been a naughty little boy,> I heard as a naked woman suddenly appeared in my lap.

She sounded like… "Setsuko?" I asked.

<Yes,> she said and I suddenly tensed up. Oh shit! She caught me in bed with Kouki! An electric jolt ran through my brain as I suddenly awoke completely. <But don’t worry, I know just how you can make it up to me.> And then she was kissing me!

Hey, I may not be the smartest guy on the planet, but when your fiancée kissed you, and I mean like all-out tongue in my mouth kisses you like she was doing now, it means she liked what you did. Maybe it turned her on knowing I was a real stud and had just nailed another woman? And here I thought she’d be furious. Well, all’s well that ends well I figured and kissed her back.

I’d never kissed her, but man, did she have a long tongue. I swear it was all around mine and going crazy. Of course, I was happy to get my hands on her ass and start squeezing and pulling on her hot flesh, but then she wrapped her hand around my cock and I was putty. Her hands started pumping up and down my only semi-hard shaft, quickly building back up my previously satiated desire for sex as she really knew how to manhandle me.

I had almost forgotten about anyone else also being in the room when I felt the bed shift and Kouki moan out, "No, Kenji… Don’t… Ahhh." I looked over, and in the dim light of the moon which only really illuminated the open doorway and floor, I could just make out the shadowy silhouettes of Kenji now lying atop of Kouki beside us. Was he...? "We shouldn’t…Ummmpf!" Kouki moaned again before I saw Kenji’s hips come down and he muffled her objections by placing his mouth on hers.

They were! He was totally fucking his own sister, the incestuous bastard! Well, what did I care? I’d already notched that twat on my belt, so he can have the sloppy seconds. Besides, I had Setsuko to fuck now and she seemed rather eager to go, so why not. How many other guys got to bang two chicks in one night?

As if reading my mind, my bride-to-be broke our lip lock and asked in the sexiest tone, <Are you ready to fuck?>

"Oh, yeah baby," I nodded and spanked her ass. "I’m ready for ya."

<Good,> she said with a sly giggle, and then suddenly her hand pushed me down on the bed hard. I hadn’t been prepared for that, much less that she was so strong, but I just went with it thinking to let her have her way the first time. But then she grabbed my legs and forced them up over her shoulders.

"Baby, what are you…" I asked concerned, not seeing any way to do the deed in the position she was putting us into, and getting worried by how easily she was able to push me around. Then I felt something hard press up against me. "Hey now, what the fuck is…" Then it started to push against my ass! I tried to struggle, but her hands on my thighs held me so tightly as to cut off my circulation. Then she pulled my hips up, pinning my back to the bed and further preventing me from moving.

<Try to relax baby,> Setsuko laughed with a creepy echo in her voice. <It’ll hurt less when you lose your virginity.>

"My what!?!" I started to freak out in confusion. I’d just fucked Kouki, and before that had already bagged Yuki once before I left on that damn war. "I’m no vir…" I started to tell her when it actually hit me. Both figuratively, and literally. What she meant was that my ass was still virgin, having never been fucked by a dick before, and somehow she had a dick and it painfully started piercing open my terrified asshole. I screamed in horrible pain, probably waking up more than a few other people in the house. Fuck did that hurt!

As much as Kouki had whimpered as I’d forced my prick in her bum earlier I figured she was just acting like a girl. Besides, she’d asked me to do it so I figured she must have liked it, but this fucking hurt worse than anything I’d ever felt before. "What did you put in me?" I cried out through my tears and begged, "Take it out!"

<But, baby, you said you were ready to fuck,> Setsuko laughed, and then I felt more of her phallus push inside me, opening up deep parts of my shitter that had only expanded that wide when I was constipated. Fuck! Whatever she put inside me must be as thick as a tree trunk! I knew she must have split me open down below and I was probably gushing blood all over the bed. I didn't want to die, especially not like this.

"Please, take it out…" I whimpered again, struggled to escape again, but found myself totally immobilized as she held my legs and ass up with all my weight resting on my shoulders. "You’re killing me." Setsuko just laughed and then thankfully I felt her pull back, withdrawing her invading spike from my rump, but only for long enough to get some room to drive it back inside, deeper and harder than before.

Cruelly she then grabbed my cock so hard I thought she was going to rip it off. My tears already flowed freely from my eyes at the pain of her ripping open my asshole, but then she taunted me, <If you hate it so much why are you so hard?> And to that she stroked my prick in her vice grip and only then did I realize she was right. While I’d never experienced such savage pain I was indeed as rigid as a kunugi oak tree. And once I realized that I also then recognized that a part of my body really liked the filling sensation of her pole in my rear end.

After that, I stopped resisting, finding that the pain was lessening with each of her thrusts and enjoying the sensations of my abused colon. I couldn’t resist it anymore; it was like a switch had been turned in my head. In desperation I took my erection away from Setsuko and started jerking my meat for all I was worth, having never felt too turned on in my life, despite the unpleasantness of it all. She just laughed and used my excitement to let her fuck me harder, the stinking swell in my anus now causing my entire body to tingle with fireworks.

"Ready to get filled up with my baby batter, little sister?" Kenji teased Kouki. I’d almost forgotten about the other couple fucking beside us, but hearing that Kenji planned to knock up his step-sister was fucking sick and hot!

"No. You can’t!" she protested at only a whisper as he sped up his thrusts to finish up. I could tell by the faster pace slapping of their sweaty flesh it wouldn’t be long now. "No, no, no, no…." Kouki slowly built up, begging with each thrust. Then with a harsh groan from Kenji, she changed her tune. "Yes!" she cried out in delight. "Oh gods, that feels too good! Yes! Fuck! Fill me with your babies! More!" she wailed as it sounded like they were finishing up. Just hearing them and picturing Kenji’s cock spraying his cum started setting of my own climax.

<Yes, that’s it. Cum for me, my cute little sissy whore,> Setsuko cheered me on, but I was already over my limit and couldn’t stop now if I tried. My body clenched up and in this position, I involuntarily ejaculated a hot rain of sperm all over my own face and torso; at least a few drops landing on my tongue and trailing a salty course down my gullet before I could close my mouth. <Yes!> Setsuko cried out and then I felt her rod in my bum twitch and quiver as if it were itself a real cock and then flood my insides with a warm liquid that stung me like bee venom. I was still climaxing, and while I felt it, confused and yet somehow happy that the anal invader was in fact a real cock. Was she packing this whole time and just kept it a secret?

"Do you really want to see it?" I heard Kenji laughingly ask off to my side as if he had read my mind, and then a candle across the room on a table ignited even though no one was around to have lit it. And while that should have been worrisome on its own it paled to the real amazement of the couple that had just come in and started raping us.

If that was Kenji still atop of his sister, he no longer looked much like he had before. His skin had darkened into a vivid red like hot fresh blood and from his head now two sharp black horns extended up in a curve. "What the…" I started to boggle, but stopped after I glanced over and saw Setsuko had transformed in much the same way, yet far more shocking. Her skin, once pale alabaster now glistened with her sweat like a ruby, and her mane of blonde hair had transformed into a tangled forest of bluish onyx on her head and above her crotch. And that was where the most amazing thing of all was; as she eased me back down to the bed what emerged from my body was indeed a very real cock, vicious and evil-looking as the hard beast was coursed with thick purple veins and still oozed out a large drop of her white sticky cum from her tip.

I couldn’t break eye contact with the magnificent tool as she walked around the bed. It bounced and swayed as she moved before presenting the demonic prick to me for a closer inspection. Perhaps worst of all, I found I was envious of how beautiful it was. <Do you like my new toy?> she asked and I couldn’t help but nod in awe as I took in the grandeur of it. She still looked like a woman, albeit a much different one that I’d seen yesterday, and from my vantage looking up at her standing over me now I could even see her womanly slit hiding underneath this massive beast of a cock. <Kiss it and show me your devotion then, lover,> she ordered and knelt down over my face.

I didn’t even resist in the slightest now. My mouth simply opened wide in acceptance of the salty tipped prick and then before I knew it my lips were stretched to their limit as my throat bulged with her girth. I happily let her pound my face with her coarse black pubic hair tickling my nose and couldn’t wait to finally taste her creamy load. From that moment on my body and soul belonged to them.
