137. Go for a walk on the beach.

Gluttony/Lust Chapter 3: It's a dog eat dog world.

"That sounds romantic," she smiled and took my arm. "I know just the place." Together we walked to the northwestern part of town to a place where you could see the guarding watchtower in the distance, but we walked back south along the beach with the sea to our right and the cliffs growing up to our left. The eastern beach was bigger, but this was more private since it was smaller. Also, it ended in just a quarter-mile in all the large rocks with the ruined temple far above. But with the sun setting on the water as we walked hand in hand it was very romantic.

Walking shoulder to shoulder I reached over and ran my finger up her cheek to push some of her cute pink hair over one of her pretty little ears. She smiled and turned her head towards me and looked so beautiful at that moment. I bent in close, knowing that I was going to kiss her and she would let me when a sound broke the moment. It was a barking dog.

"Good boy!" I heard my sister's voice cheer and laugh. Looking down the beach I saw her come along the beach finishing her own walk with that same stray dog from before, playfully throwing a driftwood stick into the shallow surf and watching him bound after it to bring it back to her. Then she saw us. "Oh. Hi Yuki…" she said noting how close we were standing and holding hands. "Kenji…"

The three of us were at a momentary loss of words, but that's when the dog ran back in, dropping his stick and getting violently mad at me again for no reason. Something inside me took over, threatened by this simple mindless beast. "ROOOWRRRR!" I let loose a bestial snarl at the small creature and felt every hair bristling on my body. The dog backed off in fear, as did Yuki, but Kouki took the dog's defense.

"Stop it!" Kouki scolded me. "You're scaring him!"

All my rage then became directed at her, "Shut up! All you ever do is bitch at me! You know what dogs do to bitches?" I could feel my body changing as my shouts became feral and wild, turning into snarls by the end of my rhetorical question. My clothes started to rip and I could smell their terror at watching my transformation. It was so sweet and tasty, I needed more! "They fuck them!" I snapped at her.

Then they ran and it was like a **** to me. I was thrilled to chase them even though I easily was able to outrun them when I dropped all fours with my clawed paws digging into the sand. I snarled at the hems of their dresses and bit to rip away large swaths of clothing, enjoying their delicious panic as they struggled to get away. The stray dog even tried to defend Kouki, but it took only a second for my massive jaws to clamp down around its tiny neck and snap it right open. Its blood was sweet and bitter at the same time, and while the taste of victory was like honey on my tongue the rest of my prey’s fear tasted even better.

I lost interest in it quickly in the mangy corpse and continued harrying my two bitches as I shredded their clothing, only putting a few bloody scratches and shallow nips into their soft tender flesh. When the beach ran out and I finally had them cornered up against the rocks they were both already exhausted and down to just their bras and panties. At that point, Yuki decided with nowhere left to run she would try to reason with me.

"Kenji!" she yelled and I stopped just sort of pouncing on her, curious to what she could possibly say. "This isn’t you. You’ve been taken over by some kind of oni. Fight it, Kenji! I know you are still in there somewhere." I consider her for just a moment, walking up close to her as she holds out her hand to me. I can still smell the fear in her, but she’s trying to put on a brave face. I actually let her think she’d gotten through to me for just a moment before I jumped atop of her, pinning her to the ground as I rammed my cock into her crotch so hard it ripped right through her panties to dig its way into her dry cunt.

Her shriek of pain was music to my ears, as was Kouki’s and I quickly started thrusting the extended length of my new massive cock out of its sheath. It was a strange and different feeling, like getting a second erection after I already started banging Yuki’s nice tight cunt. The tip of my cock swelled, forming a knot on the end that prevented it from being able to come out easily so that no matter what, she was stuck with me inside of her until I came, which wouldn’t be long given how pleasant her thrashing to try and get away was making me feel. The thought of trying to run past us crossed Kouki’s mind, but one snarl from me as my eyes stayed locked with hers and she shrank back against the rocks before turning away from my bestial gaze as she started looking for another escape route.

I didn’t give her long before my first injections of sperm started flooding Yuki’s fertile womb. She must have liked how that felt because by the time my knot shrunk enough to pull free of her abused vagina she was moaning and shaking there just lying in the sand. With her domesticated, I left her and approached Kouki, who had started trying to climb off the tall slippery rocks, but hadn’t made much progress. That put her in just the right position so that I bit at her ass, leaving a small bloody scrape, but also hooking her panties and tearing them apart and I yanked her back down.

She tumbled and rolled into the sand, covering her body in the scratchy grains, but she was still aware enough to try and right herself, but I wouldn’t be denied. With her on her hands and knees, scrambling to stand I took her, much like Yuki, but this time I was able to insert myself fully with her in the correct doggy position. "No!" she screamed as I powered through her fresh and unbroken womanhood, rending the fragile thin fleshy barrier that Yuki hadn’t had. I hadn’t known Yuki was a slutty bitch until then. Only then I could tell the difference of what taking a virgin felt like, but that turned me on for my next mating even more.

My fore paws grabbed at my sister’s hips and pinned her tiny hot twat to my balls and this time my expanding knot at the end of my cock pierced up inside my lover’s womb, locking her into frenzied copulation with me that was even better than the first quickie fuck I’d given Yuki. I nipped at my bitches neck as I panted out how good this felt, but found I couldn’t make words anymore. My mouth had fully become canine-like so all that came out were howls and barks, but none of that mattered anymore. The only thing I cared about was fucking Kouki and filling her with my spawn. She was my true prize and Yuki was just the appetizer.

I was just about to finish when I howled out my dominance, but saw something that distracted me. I wouldn’t have noticed it if I hadn’t thrown my head back, but it was the monk, suicidally jumping off the cliff from the ruins above us. I would have laughed, but he was going to land right on me so I reflexively tried to move away, but was locked still within Kouki’s uterus by my own bulbous dog cock that prevented her from getting away. She had a **** grip on one of the large rocks that I had shoved her up against as I defiled her.

I couldn’t react fast enough and then with a mighty blow he slammed a small cube he held into my forehead emitting a bright dazzling light at the same moment my body started spraying my second load of semen deep into my sister’s belly. She was crying out as her womb contracted in unbidden pleasure as it accepted my load, but my head seemed to crack open, letting all the anger and hatred I’d felt so recently rush right out of me. I was sure I was dying as a collision like that should have split my skull in two, but after a second of intense fireworks in my brain the monk gracefully landed on his feet next to me as if his acrobatic attack had all been as easy as walking.

In his hand now rested a glass cube filled with what appeared to be bright purple worms, but I could tell that it was really the oni that had been controlling all my perverted thoughts and so many other crazy things, such as this mystical transformation of mine. Then I realized, I wasn’t human, but a dog! I was as big as a person, and maybe twice my original weight, but a beast still all the same. Oh crap! And I was still mounded atop Kouki with my softening dick still seeping the last vestiges of my recent orgasm into her!

I tried to speak, to apologize as I backed up, disengaging my sloppy dick from my poor innocent sister's gaping cunt, but all that came out was a pitiful whine. Even worse was the guilt I racked up as I couldn’t help but watch the gush of sperm and blood that followed as she finally collapsed to lay face down in the sand next to her sister in this vicious ****. Yuki must have passed out after I left her as she was groggy and still trying to clear her head lying out on the darkening beach as the sun had long since set and all the bright reds of the vanished sun had shifted to vibrant purples.

I looked back to the monk to try and get him to help them, but he had vanished from the end of the dead-end beach as if he never existed, and with him that bizarre cube he held that had freed my mind of the evil presence that had left me curse with this body and the horrible things I’d done to both of these girls. Unable to aid them in any other way I licked Yuki’s face with my long wide tongue as a dog would and that seemed to help her come too.

"What happened?" she asked no one in particular as she rubbed her brow before looking around. I bowed my head and looked as sorrowful as I could, but without being able to speak I had no idea if there would be any way I could ever make them understand that this wasn’t my fault. Then I had an idea!

She looked at me confused as I started pawing at the sand, then saw Kouki passed out next to her. "Kouki, are you alright?" she said with concern as she helped my sister onto her back and wiped the sand from her face.

"I’m not sure…" she groaned. "I feel so sore."

"Yeah, tell me about it," she smiled slightly before returning her attention to me. "Something’s happened to your brother."

I was worried it would be too dark for them to see properly, but then the bright full moon crested out from behind the southeastern cliff and covered us in its soft pale light. More importantly, it let the word character I had carefully drawn into the sand be read clearly.

"Sorry?" Kouki said as she read it. "Kenji, is that you?" I nodded. "What happened?" she asked, just as Yuki had when she had woken. I wasn’t sure, but I think the trauma or the magic had somehow caused some memory loss in both of them. To me, that actually seemed like a godsend! Hopefully, they would find a way to forgive me for what I’d allowed happen, but for now, I just moved to the side and drew out another character in the sand.

"Oni?" Yuki asked as she read that one. "Well, my Granmama says that there are evil oni and spirits that can take over your body and do horrible things. Though usually to those that are lacking in virtue and generally acting slutty."

"I would never…" Kouki began, but Yuki cut her off.

"Looks like you already did," she said pointing at the drying sperm sticking her puffy cunt lips together. "And me," she said rubbing her own crotch. "Some evil spirit must have infected us and made us all have sex."

"And turned Kenji into a dog?" she cried out in utter disbelief. To get her attention and try and make her believe it I barked and nodded my head happily. "If you really are Kenji, prove it," she declared still skeptical. I thought for a moment and moved to another spot and wiped my paw across some sand to smooth it down before scrawling two more characters to make it unmistakably clear to her who I was.

"Matsu," Yuki read aloud as I finished the first one.

"Moto," Kouki finished before I’d gotten more than two swishes of my crude paw writing done. I still finished it, while they just watched, then also wrote my first name, just for good measure.

"Oh, Kenji!" Kouki cried and dropped to her knees right on my writing to hug me. "I’m so sorry. I don’t know how this happened, but I promise you I’ll look to find a cure and won’t leave you until you are human again." I rested my head on her shoulder and let her hug me, unsure of what else I could do.

"Well, I’ve got a farm, and Granmama might know something," Yuki suggested. "Why don’t we go and try and see if our clothes are anywhere along this beach first, but my house is not far from the bluff. You can sleepover with me tonight."

"Thanks, Yuki," Kouki said as she stood and rested her hand on my head and pet me between my ears as we started walking back north along the moonlit beach.
