I gave her a grin, "We've come this far. Might as well go the distance and get you your PhD."

Moisture fogged my sister's eyes and she said, "You are so wonderful, Cal." Then, "Okay, let's do it."

She tightened her clasp on my fingers and began moving toward the mat on the floor. I moved with her and tried not to think about the act to which we were about to commit—pretend to commit. One of the attendants gathered herself behind Tara and reached out to take off her flower necklace. Tara bowed her head and allowed herself to become now and once and for all utterly naked, as I was. In this moment I could not help but look directly at her voluminous breasts. Her nipples were hard within perfectly symmetrical areolas. It was with effort that I pulled my eyes from them and back to Tara's gaze. Fortunately, my sister didn't seem to mind; she was smiling.

She began reclining.

Down, she lowered herself down onto the mat, all the while drawing me toward her. I let myself be guided by her. I got down on my knees as Tara reclined onto her back, parting her legs, letting me settle. In this moment I paused and took in the scene: my sister, lying back, legs parted, her womanhood exposed, welcoming, inviting...her stomach moving with short nervous breaths...her breasts swelling, heaving, beckoning. If this were any other woman I would have found myself overwhelmed and would have ravished her by now, burying my face in her breasts, showering her with kisses, licks, nibbles, and of course the thrust of my manhood as it probed, pleadingly, against and into her sex.

It was also in this moment that I found that I could no longer hold back the carnal instincts of my being as the blood flowed into my loins and my erection began to swell. I tried to imagine I was a movie star, doing a love scene, surrounded by cameras... But it was no use; I was growing hard, growing erect. For my sister. I was simultaneously aroused and embarrassed, worried that once Tara saw—or felt—that I was physically responding in this way she would be horrified and recoil from me. That, of course, would blow the whole charade and ruin her project, not to mention her respect for me as a brother.

Thankfully in this same moment the attendants were draping the blanket over us so that even if Tara looked down between us my erection would be hidden by dark shadow. Very carefully I positioned myself so that I was now kneeling between her spread legs, supported above her by my straightened arms, hands on either side of her. As we shifted around I felt my legs occasionally graze her thighs, which did nothing to help subside my now fully formed erection. I was completely hard, huge and protruding.

Saying something...Zami was saying something. Sounded far away.

"Cal," Tara said softly, "she's asking you to lower yourself." She swallowed. "To...enter me."

Despite the proximity of our two naked bodies it was pretty obvious to someone watching—the elders—that I was no where near being on Tara's body, let alone entering it.

"Well," I said, trying to give her a reassuring grin, "it's time for some push-ups."

She gave a nervous nod and I lowered myself down, trying to keep my butt up so as not to accidentally touch her with my hard penis. I got low enough to feel her breasts begin to squish warmly against my chest, our mouths only an inch or two apart. Then I pushed back up, allowing myself a soft sigh—a bit of acting, yes—before lowering myself back down for another push-up.

After two or three reps, I saw a worried look in my sister's eyes, but her attention was actually turned toward the elders. I followed her gaze toward them and saw almost comically puzzled looks on their faces. I glanced back at Tara.

I said in a whisper, "They're not buying it, are they?"

She shook her head.

I swallowed. "That means I have to get closer, Tara. If we're gonna sell it."

She nodded and whispered back. "It's okay, Cal. Do what you need to, but only if you're still okay with this."

"I can do this. I'm okay with this."

"Thank you, Cal."

Closer. I had to get closer. So I did it. I let myself ease down against my sister, this time letting my hips come down as well. I thought about warning her about my erection, because there was no way I was going to keep it from touching her. But I couldn't figure out what to say. I figured if it hit her she'd either freak out or not. The moment of truth.

Lower...lowered myself down. My chest again pressed against Tara's, our flesh searing together, our mutual rapid heartbeats meshing. I lowered my head down to one side of Tara's bringing my lips close to her ear. Her mouth was close to my ear a well, I could feel her warm breath. At that point the tip of my penis grazed against the inside of her thigh, high up where it met her pelvis. I heard Tara take a quick sharp intake of breath at the realization of what was touching her. To add insult to injury, I must've been leaking precum, because the sensation was not only warm and electrifying, it was wet.

"I'm sorry," was all I could think to whisper to my sister.

I lowered myself all the way now, and as our bodies connected from chest to stomach to pelvis to thighs my cock slid up against the front and top of Tara's smooth bald vagina. The pre-ejaculate fluid ebbing out of my urethra provided a lubricant that helped me slide firmly against her, and it was all I could do not to groan with the guilty pleasure I absorbed from this carnal contact.

Tara took another breath, held it, then sighed. I must've repeated "I'm sorry" a few more times, because Tara finally said, "It's okay, Cal. It's okay." She even reached out and gave one of my butt cheeks a little reassuring pat. "It's...just a natural reaction."

I was tremendously relieved. It would've been devastating to have her freak out beneath me, thus blowing the whole charade and of course destroying all of her work with the Kasabai. Not to mention, I still worried, the potential violence these people might wreak upon us.

Giving a sidelong glance over at Zami and her ladies I was further relived to see smiles and nods of approval. Tara's breathless surprise from the contact my penis was having against her was convincing the elders that intercourse had now commenced.

"It's working," Tara whispered, coming to the same conclusion. "Keep it up."

Keep it up, she says. Oh the irony of those words. It was definitely up. And I did what I was told: up, down...up, down...sliding against her, my cock sliding against her, a slick trail of precum now well established along her mons pubis. This was quickly becoming the most torturous thing I had ever experienced. Every fiber of my being wanted to simply surrender to the sexual urge, to push into this woman's vagina, or at least hard enough against the outside to stimulate the nerves further. To stimulate the urge, the desperate desire to ejaculate.

I couldn't look Tara in the eyes anymore. On the downward movement I lowered my face toward one of her ears. On the upward movement I clenched my eyes shut, desperately trying to maintain control.

Throughout this supposed consummation I vaguely heard Zami chanting her blessing. Words, voices, breathing, drums...how much more could I take? When could I end this, or make it look like I was ending it? Soon, it had to be soon!

Then something incredible happened. Almost as subtly as when she had stroked my thumb with hers, Tara made another minute yet electrifying movement: as I lowered my body down against her, with my cock grazing along her mons, she thrust her hips up.

At first I thought she simply might've been shifting her hips, having grown uncomfortable on the thin bed of firs. But as I lifted up and pressed down again, there could be no doubt that Tara was moving her hips up again. We may have still been simulating intercourse at this point, but my sister was now matching me thrust for thrust. And it felt wonderful, too wonderful. I was beginning to thoroughly enjoy dry-humping my sister, and it was useless trying to tell myself that such a thing with a blood-relative should not be enjoyed.

Saying something, she was saying something, my sister. "God, Cal...oh God."

"Yes, baby," I groaned back, getting lost in my lust.

Each time I lowered myself I was now pressing harder against her, my cock firmly pinned against her thigh, her luscious breasts smashing hotly against my chest, sweat forming between us, breath coming in short stunted jerks.

"Cal, I...we..." She didn't finish, just gripped me tighter in her arms, thrusting her hips up hard now, even moving them from side-to-side, and after a few testing moves we found a way to grind our genitalia against each other to provide more direct stimulation. I could now distinctly feel the shaft of my iron-hard cock work its way into the warm wet grove of my sister's perfectly smooth labia. How I kept from just jamming the head of my cock right into my sister's vulnerable pussy at this point caused both wonder and regret in my tortured psyche.

After a few minutes of this, lost in our feelings, I sensed that the drums and chanting of the elders was getting louder. Or were my senses just heightened in the total high of sexual plateau?

I was now looking directly into Tara's eyes, and she returned my gaze. We were not stupid, we knew what was going on. The only question was, how far were we going to take it? It wasn't just my mind wondering; my cock had practically had enough, and I was ready to burst at any minute.

Tara's soft sultry voice get me into focus again. "Cal, it's been long enough."

"What?" I breathed, realizing that I suddenly wanted to kiss her. Kiss my own sister.

"Long enough," she said, thrusting up at my own push against her. "It's been long enough, I think. We should...we should finish."

The fact was, I was actually quite close to "finishing." You have to realize, my good friend, that I hadn't masturbated in something like ten days, and I had all but fucked a girl once during that time, and then I'd been naked and surrounded by naked people—including my sister—for the last few days. You could say that I was primed, very primed, to pop with virtually any amount of stimulation. And that stimulation had been happening for a good 10 to 15 minutes.

Finishing would not be a problem.

But then I had a horrific thought. Up to this moment my sister and I had been faking sex. Even in my euphorically delirious state of lust it was logical to assume that she was now telling me to fake my finish as well. The very thought of having to end this without having an actual orgasm was not something I wanted to even contemplate. Amazingly, however, just as I was processing this in my lust-drunk mind my sister seemed to read my mind, perhaps my pained expression.

Somewhat breathlessly, she whispered, "Cal, if you need to...finish yourself, you can do it. Just," she added, "just try to keep it hidden under the blanket."

I couldn't believe my ears. Desperately I whispered, "Are you sure, Tara?" As if to give her every possible reason to change her mind, I added, "There will be quite a...quite a mess."

Tara swallowed and looked at me, taking one of her hands from the small of my back and reaching up to stroke me cheek. Then she pulled my ear to her lips and said in a voice of mostly warm breath, "It's okay, Cal. You have to ejaculate. If you don't and we end this, they'll see that you're still...still erect, and they'll have doubts."

As if to reassure me further, Tara did something incredible: she began lightly kissing my ear, then she worked here way down my cheek, ending with a very light kiss on my quivering lips. "I'm okay with this, Cal. Just let it happen."

This whole time we were continuing to thrust against one another, maintaining the rhythm almost automatically. I suddenly felt the most intense rush of emotions swell up from my stomach to my chest, almost into my throat. I could only look down at my sister with indescribable love and lust. I knew then that I had to kiss her, really kiss her, but the fear of shocking her kept me frozen. It also broke my thrusting pace.

I watched Tara's face as she realized I had stopped moving, keeping my body pressed against her. She glanced over a Zami, the attendants, and back to me. I looked deeply into my sister's beautiful eyes and prepared to thrust against her one last time, eager to make myself cum against her smooth naked pelvis and thigh. I just had to make sure I didn't shoot any of it beyond the thin reed blanket covering us, which would certainly blow the charade apart.

I don't think Tara quite realized why I suddenly paused. She was looking curiously up at me. But before I could say anything or start moving again, I actually felt movement on Tara's part. She began moving her hand again, this time between us, reaching down toward where our naked middles pressed together. I almost leaped back when I felt the fingers of Tara's hand graze against my penis.

"Tara," I grimaced. "What are you—?"

"Shh," she replied softly. "I'll help. It will be...it will be easier this way."

My lust-swollen brain hardly contemplated what my sister was saying, but my cock didn't need to be told twice. It gave a solid twitch and stiffened even harder when Tara gently wrapped her hands around the shaft, allowing a couple of fingers to flick lightly along the tip, instantly getting gooey with the profuse amount of precum that had been flowing steadily from my urethra.

"Thrust again," she said, "make it look good."

This I didn't need to be told twice. I began moving back and forth again, really playing into the part with grunts and groans. The sounds coming out of my mouth actually didn't need to be faked. As I thrust forward, Tara kept a solid grip on my penis, essentially stroking me from a stationary position as I thrust back and forth. I sensed that her hand, which gripped my cock, was also pressed firmly against her vagina, ensuring that the direction of my thrusting would indicate actual penetration to the onlookers.

Virtually drunk with desire now, and well on the verge of cumming, I gazed through foggy eyes down at my sister and just kept whispering "thank you thank you thank you."

And she was moaning back, "Oh my Cal, my sweet brother, let it happen, baby."

Another thrust...and another, and oh mother of god please just one more, one more and—and—

"Oh, Tara, baby, I'm—I'm gonna—"

"I know, Cal, cum for me, baby. Let it go. Let it all go."

And with a final powerful thrust, hard against her hand, hard against her pussy, I felt the absolute most powerfully intense orgasm I had ever known burst forth from what felt like my feet, through my legs, churned to the ultimate intensity within my balls and out like an atomic blast through the shaft of my engorged cock.

Still gripping my cock, Tara managed to shift her hand just enough to try and catch as many of the splashes of hot semen as she could. I didn't even care at this point, and I lost count of how many times my cock pulsed and spewed forth yet another thick wet rope of sticky white sperm. It seemed to go on for minutes, and I seemed to hear myself from afar as I cried out in pure pleasure, drawing the delighted "oohs" and "ahs" of those watching us.

I even heard Tara mutter, "Jesus, Cal," as she looked down between us and watched my cock continue to ejaculate against her hand and stomach. And while I had been coming, I was continuing to press firmly against my sister. Unknowingly, I had been contributing to just enough stimulation for Tara, who took in the combined sensation of my weight against her pussy and the sight of my pulsating cock. It was enough to do the incredible.

It sent her over the edge too.

"Oh, oh my God, CAL!" My sister cried out, almost as if frightened at what was washing over her body: an orgasm. A massive orgasm. Her body shook under me, her breath came in desperate, almost choking gasps. She freed one hand and gripped one of my ass cheeks. And she came and came.

As did I. As did we both. It was a moment that was instantly etched in time. Instantly infinite yet suddenly over at the same time as we finally collapsed together, our bodies meshed in a mass. The obscenely large pool of semen that had collected on my sister's midsection pasted and spread between us as we lie there, me on top, my soft warm sister breathing beneath me.

I felt her hand still against my penis, which after a couple of moments began to settle back into a slightly more flaccid state, and she let it go at last. As we panted in exhaustion, Zami cried out something in Kasabai. I blinked and looked up at her, only to find the elder smiling down at me with a look of great joy. She said something to the two attendants, whom I'd almost forgotten had been watching the whole time. Whatever Zami said she had to repeat it a few times, because the attendants, very young women, had been absolutely enraptured by what they had just witnessed—or what they thought they had just witnessed. Perhaps it was their first initiation into this ceremony too. In any case Zami's orders had finally gotten through, and they both sheepishly backed out of the hut and then began screaming something out as they ran deeper into the village outside. Within moments I could hear cheering throughout the village.

I looked down at Tara. She had been watching me, studying me, smiling at me. The smile was a relief, because in the distinctly post-orgasmic state we now shared I was afraid she would suddenly realize what we had just done with her own brother, realize that the hot fluid oozing between us was my incestuous seed, and she would freak out. But it was just the opposite; she was calm.

She said, "The girls are alerting the village about the success of our union. The village is happy for us. Zami is happy for us."

I let out a breath. "That's a relief."

Tara kept smiling.

It seemed that we should've probably have said something more to each other at this point, but Zami was speaking. I leaned my head down to allow Tara to translate softly in my ear.

"She's bestowing further blessings upon us and—oh good, she's going to step out of the hut now and give us some privacy to get some much needed sleep."

I was further relieved to know that Zami wouldn't be staring down at us anymore, but that led to another question. I asked, "We're to sleep here? Together?"

"I'd say that's logical. We are, after all, married now."

"True."

After another few words Zami left, and then I was truly alone with Tara for the first time in days. We were still pressed together, the warmth of our naked bodies combined, the product of my ejaculation still quite wet between us. I could smell it, and I was sure she could too.

"There's some water in that wooden bowl over there," she said gently. "We should try to clean up a bit."

I nodded, and with a sudden reluctance, I lifted myself off of Tara's perfect body and moved the reed blanket from over us. In the dim light I could see the mess on her stomach, and I tentatively felt the same residue of thick semen clinging to my own abdomen. I got up, stretching a little, and fetched the bowl of water. Tara sat up, then got to her knees as I returned with the bowl and set it between us. I mirrored her kneeling posture, and we quietly washed ourselves with the limited amount of cool water. The whole time I couldn't keep from marveling over and over again at my sister's glorious nakedness. Only the fact that I had just enjoyed one of the most intense orgasms of my life kept me from growing painfully erect yet again. Nevertheless, my cock protruded prominently, and my sister glanced at it frequently as we cleaned up. When we were done, we looked at each other for several wordless moments: now what?

Finally Tara, the logical doctorate candidate, spoke: "We must sleep here together tonight, to keep up appearances. I'm pretty sure we won't be disturbed, so we can hopefully get a good night's sleep."

"Sure," I acknowledged tentatively. I could see in her eyes that she had more to say, or she certainly had much to ponder, but we obviously weren't quite ready to bring up the 800-pound gorilla in the room.

To help bring things to a close, at least temporarily, I reclined back onto our "wedding bed" and pulled the reed blanket partially up my body. I said, "A good night's sleep sounds like exactly the perfect thing right now. I am utterly exhausted."

Tara hesitated only for a moment, but to my hardly concealed joy got back down onto the bed with me and joined me under the blanket. "Yes," she said, "sleep is what we both need right now after the craziness of today's events."

For the next few minutes there was a little awkwardness as to how we were going to settle into bed with each other. We didn't exactly spoon, things were still just a bit too weird for that at the moment, but finally we settled onto our sides, facing each other. The blanket got pulled up so that, though we were of course still quite nude under it, what we could really see of each other now was our faces. In the dim light hers looked angelic. I gazed curiously and suddenly quite hungrily at her for a good several minutes before the biological reality of my post-orgasmic body began to set in and I found myself beginning to doze.

In this euphoric state of half-wake-half-sleep, I sensed Tara reaching out with a slender hand to lightly stroke the side of my face and my hair.

"Oh Cal," she said in a whisper, "what have I gotten you into?"

With my eyes now closed, I whispered back, "I agreed to this, sis. No regrets."

"Thank you, Cal. You are wonderful." Her voice sounded a little distant now, but that was because sleep was fast coming upon me. From afar I heard her continue, "And the truth is...I'm glad it's you. I'm glad it will continue to be you."

Continue, she said...continue. This led to the final thought I remember having that night: this "consummation" of our marriage was really only the first phase of the ceremony....

* * *

At dawn the next morning the sound of whispering stirred me from slumber. The whispering was peppered with youthful tittering and giggling. I opened my eyes and saw that the two young assistants to Zami were the ones whispering to each other while they had been watching Tara and I sleep. What they were giggling about became obvious when I realized that Tara and I had, after all, settled into a spooning position, the reed blanket had slid off of us, and I was sporting a classic morning erection that was poking fairly squarely into my sister's ass crack. And it did my erection no good by the fact that, as last night, these two girls were gloriously nude.

It was a highly erotic sensation, of course, but I was still unsure about how Tara was going to be handling our fake post-coitus this morning, so I moved my erection away from her and slid the blanket back up, glaring at the giggling girls, who giggled even louder than then began to chirp cheerfully in Kasabai. This served to wake Tara from her slumber, and for a second she seemed confused as to where she was. But to my great relief when she rolled over slightly to see me next to her, she smiled sleepily.

"Good morning," she said, groggily.

I smiled back at her, trying to maintain eye-contact rather than stare at her wonderfully exposed breasts. "Good morning."

The girls chirped again, and Tara turned to them, listening then nodding. She said something back to them and they bowed and departed. Turning back to me, Tara said, "Part Two of the ceremony will begin shortly. You are to head to one side of the river with the men, I'll join the women on the other."

Tara, now quite used to being naked around me, got up and stretched like it was no big deal. I sat up but kept the reed blanket strategically over my crotch and my damned persistent erection. Part of the problem was that I also had to take a serious piss. Once I could relieve my bladder I'm sure my erection would go down...

I said, "Um, why don't you go on ahead. I'll be out shortly."

"Really?" she said. "I think there is a crowd gathering outside. They'll want to see us emerge together."

"Oh boy..." I puffed out my cheeks, stared down at the ground for a moment.

"Cal, what's wrong?"

"I just...need a few minutes."

Tara knelt down next to me and holy fucking god was she still so gorgeous! I forced myself to look away.

"Cal," Tara said, a note of worry in her voice, "this is getting to you, isn't it? We've definitely gone too far, haven't we?"

"No, it's not that," I said quickly. "We've made it this far, it's just...I'm...somewhat...excited at the moment."

"Excited?" The worry in her voice turned to puzzlement.

I glanced at her. "You know when guys wake up and they have to use the bathroom how sometimes..." I trailed off.

Tara finally came to a realization. "Oh my! I'm sorry, I understand now." We were both quiet for a moment. Then she said softly, "You're erect right now?"I nodded. "It would help if I could go to the bathroom, but..."

I saw Tara bite her lip in contemplation and glance around. "Here," she said at last, standing again. "Use this as a chamber pot." She'd stepped across the hut to fetch the wooden bowl from which last night we'd drawn water to wash my semen off of ourselves. It was empty now, and she set it down next to me.

"Seriously?" I said.

"You gotta do what you gotta do, right? And if we don't step out soon they're going to come back in here and get us."

"Uh...okay."

We stared at each other awkwardly for a moment. Tara then seemed to realize something and said, "Oh, sorry, I'll turn away."

I shrugged. "Hell, it doesn't matter, you've seen a much more serious bodily function of mine, I guess taking a leak in front of you can't be any worse."

Tara grimaced at me. "Oh god, Cal." But despite my crude comment we both chuckled, happy to release some of the tension that remained between us.

But speaking of "release," I felt like I was going to absolutely pop any second, so I mumbled "Fuck it" and stood, letting the reed blanket drop. Thankfully, my erection had abated somewhat, but there was still enough blood in the shaft to keep me well-engorged and sticking out considerably, much to Tara's amazement, which she quickly tried to hide in a blushed glance over to any other part of the hut that was suddenly fascinating.

In symbolic discretion, I half turned away from Tara, and bowl in hand, I took aim. For a few embarrassing seconds I was piss-shy, but eventually biology won out and I was able to let loose with an eventual torrent of urine into the bowl. It was a tremendous relief, and I was tempted to hang my head back and sigh, but I remembered I needed to concentrate on keeping everything flowing into the bowl and the bowl not spilling.

When I was done I glanced over at Tara, and interestingly enough I saw that she had, after all, pretty much watched the whole thing once I got started. Interesting. I also noticed that she was sort of crossing her ankles as she stood, and she was fidgety.

"You okay?" I asked.

"Hmm? Oh, yes," she said. "Just watching you...er, hearing you go makes me...well, I have to go too."

"Uh...well, there's room in the bowl, I suppose...."

"No, I'll make it to the river. I'm not the one who had to get rid of morning wood."

This last she said with a smirk and wink. I glanced down at myself and confirmed that my erection had finally died down so that my penis, while still quite proudly hanging down between my legs, was of it's normal flaccid size.

"Shall we, husband?" Tara asked, trying to sound cheerful again.

I grinned. "Sure, dear wife. Let's go."

Hand in hand, and of course naked, my sister and I stepped out into the bright light of the morning to find virtually the entire village gathered in a large circle around our marriage hut. Led by Zami there were energetic cheers, chants in Kasabai, and overall applause. The cheering sounded surprisingly Western, very similar to what one might expect stepping outside the church after a traditional Christian wedding. And it was quite amazing to see how wholly and thoroughly this culture embraced their own odd concept of matrimony.

As the chanting continued, Zami stepped forward and said a few things to Tara, who translated: "As the girls said earlier, you will now leave with the men for a sacred part of the river, I will head with the women to another. There will be some ceremonial hunting, more bathing of course, among other things, then we'll meet again for dinner before sundown. Okay?"

I shrugged and gave her a smirk. "Got nothing better to do."

Tara surprised me by leaning toward me and giving me a very loving but light kiss on the lips. "You are wonderful, Cal. Thank you." I could only smile stupidly at her. One of the village girls was already tugging her away, so she parted from me and shouted, "See you soon!"

Now that I was on my own with just men, I found it a little easier to concentrate. Not being able to speak a word of Kasabai, I had to pay close attention to the gestures of guidance the men gave me, encouraging me to splash and bathe with them in the refreshing current of the river. If any American with classic OCD could stand to be naked in public, he or she would be quite at home in how obsessed this tribe was with cleanliness.

The bathing was followed by Pictionary-style instructions on once again how to use a bow and arrow, how to use a spear, how to look for grubs under rocks and what plants could and couldn't be eaten. I got the sense that I was being given a crash-course in how to fend for myself and provide for my new bride. I didn't mind. As a former military officer and survivalist by trade, this was actually an incredible experience, and I reminded myself to pay very close attention to everything I could, because I would need to provide accurate feedback to Tara for her documentation.

Tara. My sister. And according to the Kasabai, now my wife. I wondered how Tara would transpose such information into her documents. Her breakthrough in integrating with this tribe was going to get her name into all of the most prominent journals of her field, I was sure of that. But if she were to refer to me as her "mate" in all this, it would most certainly cause shock and distraction from the otherwise true value of her work. I made a mental note to ensure that she obscured my true identity when she published her work. Amazingly, I didn't feel embarrassed at all about what I had done with my sister, but I was certainly concerned that Western society would be appalled, and Tara would be shunned amongst her peers. So the fact that her "husband" was her sibling would have to be concealed forever....

The highlight of the day was when I successfully arrowed a wild bore from around 30 meters or so. Certainly no archery records would be set by me today, but for someone much more used to an automatic rifle than a bow I was fairly proud of myself. And the men of the tribe seemed to take my fresh kill, so early on in my "training," as a good sign.

Though the steamy heat of the jungle never really seemed to ebb, day or night, I could sense by the changing light through the canopy overhead that it must be getting fairly late in the afternoon, and the rumbling in my stomach reminded me that I hadn't eaten in hours. I also quickly learned that dinner would be shared with the women.

Once again I found myself seated in a circle in the main hut of the village. Zami and her "elders" completed a circle that included me and my "wife." Young female attendants stood behind each of us, eager to serve us remove after remove of yet another feast. The men of the village stayed nearby, but outside the hut.

Though we had been naked around each other for days now, it was still very striking to see my nude sister again after not being around her for hours. She was so beautiful, so perfect, I knew that my desire for her was infinite now. I felt no shame in looking forward to our next encounter, though I was careful to act as "brotherly" and professional as possible. In the hours of separation it was quite possible that Tara's feelings were going in quite an opposite direction as mine. But I would find out exactly what was in her mind soon enough, because the meal was concluding, and without having to wait for my sister's translation I could tell that Zami was indicating that a return to the wedding hut was forthcoming.

As we walked toward the hut, Tara and I debriefed on our days. I updated her on the highlights of my day with the men, and she said that other than the hunting her day was similar, even somewhat mundane. She added that if anything there was a concerted effort to ensure that she did not expend too much energy.

"Why is that?" I asked.

With a sudden blush, she looked down. Her voice was almost inaudible when she answered, "To help ensure conception."

My throat went dry.

And then we were in the hut, making a scene almost identical to the one last night. There was Zami, in her ceremonial garb (but still 95% naked) aided by the same pair of young women, chanting on in a voice loud enough for the gathered villagers to hear outside. I watched Zami for several minutes, but it suddenly occurred to me that Tara was not translating for me. I turned and looked at her, admiring her beautiful face in profile, her olive skin aglow from the lamp light. Sensing my eyes on her, Tara turned toward me and gave me a slightly self-conscious smile.

"Everything okay?" I whispered, not wanting to intrude upon Zami's preaching.

Tara nodded, then whispered back. "Just absorbing what's going on." She glanced at Zami, who had paused but realized that Tara was probably just translating, so she picked right back up. My sister went on, "We're going through the usual blessings of the marriage, with high hopes that our first night of consummation was happy and healthy and to the satisfaction of the God of the River, that sort of thing."

I nodded, listening, watching my naked sister.

She quietly continued, "Loosely translated, last night's...union...between you and I represented Light penetrating through the Forest, through the canopy. The Light brings Life." She turned to me, "You, of course, represent that Light, and my...opening myself to you represents the welcoming of the Forest. The Fertile Forest. And Light brings Life, as is expected of your..." She trailed off.

"My what?"

Tara glanced back and forth between Zami and me, but her eyes eventually settled on mine. "Well, your...your seed, of course...that's the Life you are bringing to me."

The sudden memory of the sight and feeling of my "seed" flowing out from my cock and splashing against my sister's flat stomach and the bottoms of her heaving rounded breasts momentarily blinded me. It was such a raw moment, so erotic, so amazing...but through the fog of lust that was filling my mind once again, I picked up on what Tara was getting at. As with the union of any man and woman in any society, the production of children is of course expected and encouraged. Under normal circumstances a new Kasabai husband and wife would have actual intercourse, not a simulation. As far as Zami and the tribe was concerned, my sperm was now flowing through Tara's body, and the blessings being bestowed upon us was meant to encourage conception.

Trying to steer my reeling mind back to rational thought, I quietly asked, "If last night represented my bringing life to you—which we successfully convinced them actually happened, I might add—why do we seem to be going through the same ritual again?"

Hearing myself ask that, it occurred to me that Tara would sense that I was reluctant to repeat last night's ceremony. I most certainly was not reluctant, but I was concerned that the more we had to simulate things, to more likely our charade would be discovered, and Tara's whole mission here could be blown.

If any visible expression of those concerns was readable in my face, Tara didn't seem to notice or be bothered by it. Actually, at this point she was only half paying attention to me, half to Zami. Ever the anthropologist. After listening to the leader of the tribe for several more minutes, Tara leaned toward me.

"Although I can speak Kasabai fluently, there is still the challenge of correctly interpreting some of the analogies and metaphors they use. In one sense, it does appear that we will need to repeat our...our consummation, but something about it will be different."

I swallowed and tried not to let the sudden excitement of "repeating our consummation" work its way down to my loins, which would most assuredly lead to an embarrassing erection. I whispered back, "What will be different?"

Tara held up a finger while paying close attention to Zami. "She's getting to that." More Kasabai chants, more words, more preaching. Finally, Tara lowered her finger and glanced at me, her brow furrowed slightly in curiosity. "Our consummation will now symbolize, to translate literally, 'the flowing of the River of Life through the Forest.'"

I thought about this for a moment. Last night, Tara, as the woman, represented the Fertile Forest, and I was the life-giving Light. If she remained the Forest again, I was now the life-giving River. So what made it different for me?

As if reading my mind and ready to explain, the young assistants to Zami stepped forward and moved to either side of Tara. They gently took her arms and guided her toward the long reed mat that had served as our wedding bed the night before. As she stepped away from my side I selfishly enjoyed a full view of my sister's long slender nude body. Her buttocks were high and taught, her thighs lithe and muscular from regular exercise and a limited diet.

I felt my loins stir in anticipation.

Thankfully I happened to be moving my gaze back up toward Tara's slender shoulders and her long soft blond hair cascading between them at the moment she glanced back at me. Our eyes locked. Once again concern was in her expression, and I knew the question on her mind: was I still okay with this? Despite my growing lust, I still felt an extreme fondness for my sister—in fact, much more than simple fondness now—and with as much warmth and affection as I could convey, I smiled reassuringly at her, adding a slight nod. She nodded back and allowed the assistants to continue to guide her. They stood her toward the center of the mat and then eased her down into what was at first an upright kneeling position. From there she was encouraged to lean forward, onto her hands, then elbows. This caused her luscious rear to point upward and back toward me. Only a few feet away I had a completely unobstructed view of her slightly parted ass and fully exposed and completely smooth vagina.

My erection grew.

Zami noted the visible evidence of my desire at once and said something with an approving tone in Kasabai. One of the assistants moved from Tara to me. She paused in front of me, openly and unabashedly admiring arguably the largest penis she'd ever seen in her life. It only fueled my erection to look at her in turn, her lovely young dark-skinned naked form, but my lust was reserved for my sister. And I wanted her now.

Zami uttered a slight grunt, startling the pretty young assistant back to her task, and she took my hand. I allowed her to walk me the few steps toward Tara until I was standing directly behind her upturned ass. My cock felt so hard, so huge, it actually eclipsed my view of Tara's behind as I looked down at her, the length of my shaft obscuring her ass crack from my point of view. It was with a sudden shock back to the reality of the moment that I realized this whole time Tara had been turning her head, looking back and up at me. And here I was, standing naked behind her, as fully erect as ever in my life.

I felt my face redden. Last night's situation had been different: it could be argued that my erection had understandably occurred by the physical contact and repetitive motion of moving back and forth against my sister's naked flesh. Up to this point I hadn't even touched her, yet here I was, a raging cock with a man attached, little else.

Then something wonderful happened: Tara give me a reassuring nod. We were committed to this charade, come hell or high water. I took a deep breath and nodded back, feeling slightly relieved. As this exchange of approving expressions was happening, I felt both assistants now, one holding each of my hands, gently pulling and guiding me down to my own knees, my cock now mere inches from poking into my sister's backward facing genitalia.

At this point, at this proximity, I could smell my sister! It was a scent that I found intoxicating. I glanced down at the source of the scent. With a perfectly laser-smooth pussy, there was nothing to obstruct the fact that she was wet, apparently as stimulated as me! I was so enthralled with the thought that my sister was as eager as I was, I practically jumped when I felt a pair of soft hands on my shoulder: it was one of the assistants. The other was kneeling near Tara's head and encouraging her to lower her upper half even further. I, in turn, was guided to lean forward to the point where I was now on my hands, and as we shuffled slowly into these positions, it happened.

My cock brushed against my sister's ass.

We both gasped, and in a childish moment of panic I lifted up slightly, as if by touching the tip of my penis against her the electric current it generated would shock the two of us into the reality of what we were doing, something unspeakably taboo. I looked down between us and saw a small wet spot on Tara's right butt cheek, and it was only then that I realized I was already drooling copious amounts of precum. It was so enthralling I almost felt like the next time I even so much as grazed Tara's body with my penis, it would explode into the largest climax of my life.

But somehow, slowly but surely, we lowered ourselves even further. Although it still sent shivers of lust through every fiber of my being, I miraculously did not climax the moment my penis touched my sister's naked buttocks again. In fact, the shaft was now resting snuggly in her crack. But I was still supporting a great deal of my weight on my arms. Arms that were trembling, muscles flexed out to the max.

Tara seemed to sense that I was fatiguing quickly. She spoke softly, "Cal, relax down against me if you need to. You'll never be able to stay up like that."

"I know," I said through gritted teeth. "It's just...I mean...I'm not sure how we're going to be able to...simulate this if they just stand there and watch us again."

Tara got my point very quickly, and this caused her to twist her head around again to look at me, quite a bit of worry in her expression. But as she met my steady gaze some kind of process seemed to occur in her mind, for her expression began to soften, and as her eyelids dropped a little, I even got the sense that she was going to—

No, I couldn't even tempt fate by thinking it!

Yet still she stared at me. Oh god, I thought, my body trembling. Are you going to ask me what I think you are, dear sister?

But then her expression changed again, and her eyes looked away from mine to some point just behind me. Before I could look back to see what she saw, I felt it: the girls were draping the long skin and fur blanket over us. Now, as last night, our naked bodies were "censored" save for our feet sticking out one end of the blanket, and our heads and shoulders the other. This of course made the decision about how to handle Night #2 an easier one: it would be like Night #1.

At this point, with as far as we had taken this charade, I would have been absolutely kidding myself if I tried to deny the almost primal desire penetrate my sister. But as consumed as I was with such wonton lust for the woman beneath me, I still cared about her enough to realize that such an act would change everything, no matter how far we had already taken things with our continued mutual nudity and simulated sexual actions. So that just left having to determine how best to position ourselves under the crude blanket to make this second act of marital consummation look believable. Tara apparently had figured this out already, because I could feel her begin to move beneath me.

"Lift up a little," she requested, her voice a little unsteady. "They know you're resting against me now. You need to make as if you're going to...enter me."

In complete amazement at the words coming out of my sister's mouth, I knew that she was making sense from a practical "plumbing" standpoint. I indeed lifted up, and another electric shock of pleasure zapped through me as I felt Tara shift her weight slightly to one elbow as she used a free hand to reach back and tentatively grasp the shaft of my penis."Jesus, Tara," I moaned.

"I'm sorry, Cal, but with you holding yourself up on your elbows like that, one of us needs to make as if to...well, to make it happen."

I closed my eyes and let her guide me...but to where?

"Let me know if this is too uncomfortable," she said, and I felt my stiff cock being angled out away from my body, almost straight down, and then I realized what she was trying to do. "Just need to get it down and...in-between," she said, her voice raspy now, her breathing quickening.

She parted her legs a little more, angled her hips just so, and then I felt the shaft of my penis being pulled down and in-between my sister's inner thighs. The upper length of my cock was now pressed firmly up against her moist labia. I shifted my weight as we connected this way, and a sudden gasp escaped Tara's lips.

"Ohhh...Jesussssss!" she exclaimed.

I froze solid, terrified that I'd hurt her or something. "Are you okay, Tara?"

"I'm sorry but...I...oh, Cal!" was all she could utter.

Her body began to quiver.

"Oh, I can't help it, Caaaaaallll!" I felt a sheen of sweet sweat suddenly form on her back, and incredibly it seemed to get warmer and wetter where my cock pressed against my sister's pussy.

Tara was in orgasm.

Holy Jesus, my sister was experiencing a powerful climax, and this was just with my pressing against her, not even moving! All I could do was lay there, my teeth clenched tight, my body stiff and shivering in excitement, as this incredible orgasm seemed to bubble up from deep within Tara's core. It seemed to build and build, and last and last, and through the whooshing sound of my own blood coursing through veins near my eardrums, I could hear even Zami and the girls let out their own exclamations of wonder at how sudden and how powerful my "wife's" orgasm was.

Back on both hands and elbows now, head pressed against the mat, Tara pushed back and hard against me with her pussy.

"Oh Cal...Caaaallllllll...ssssssooooo....soorrrrryyyy!"

Her voice was little more than gurgling now, so completely did this orgasm sweep through her. But from what I could make of her words I sensed that she felt quite guilty about the pleasure she was experiencing by her own brother's touch. This was still taboo, still against what our rational natures should be allowing. But it was happening, goddammit, and I did not want my beautiful sister to feel guilty about it. I knew now that I was hopelessly and deeply in love with her, and I wanted her to feel perfect, to feel like the princess she was.

"Shh," I soothed her softly. "Just let it wash over you, Tara. Just let it happen, baby."

I wanted to take her hand and reassure her, but this required me shifting my weight so that I could move an arm up toward hers. This shift caused the shaft of my downward pointed cock to slide several inches against my sister's slightly parted pussy, and when the head of my cock grazed Tara's heavily swollen clitoris, she exploded.

"Ohhhhh! God! Oh god, Cal! OH GOD YES!" she wailed at the top of her lungs. It was still hitting her, a full minute in, maybe more, and so powerful were her cries of joy that even Zami and her assistants were stunned, and I could hear murmurs of amazement from outside the hut.

It was so intense, in fact, that it became infectious. With all this anticipation, all the build-up to this moment, and now with such proximity of our bodies, of our exposed and sensitive genitalia grinding against each other, there was no way I could maintain control. It was almost as if my body took over on its own as I began to grind even harder against my sister, pushing the shaft of my cock up and down, up and down, against her perfect pussy.

This only re-intensified her marathon orgasm, and I swear I could feel her gushing at this point, because just before I climaxed I felt a literal torrent of warm fluid wash over my shaft and balls. But climax I did, and my sister and I both cried out together. I felt my balls tighten, and my semen began blasting great thick warm ropes from the tip of my cock and spattering wetly into Tara's thighs and the reed mat beneath us.

Somehow, as our mutual orgasms were exploding and merging, my hand found hers, and we gripped each other like lovers....

* * *

I have no recollection of what happened immediately following the mutual orgasm I'd experienced with my sister. All I knew was that at some point in the middle of the night I'd woken with a start to realize that it was pitch black in the hut, the lamps having long since burned out. The village was quiet, and the only sound I heard was that of Tara breathing deeply next to me. Not just next to me, curled up tightly against me. The night of our first "consummation" we had felt awkward around each other, and though we'd slept together, we'd remained somewhat apart most of the time.

Not tonight. At some point soon after cumming together, Tara and I had drifted off into sleep in the natural position of me spooning against her from behind, and her snuggled directly within my grasping arms and legs. This night had turned out to be slightly cooler than the previous, and with only a loosely stitched blanket to cover our naked bodies, we enjoyed the warmth of each other's embrace.

I lifted my head just enough to find a soft spot behind my sister's ear, where the warm skin of her slender neck met her hair, and I gave her a soft kiss. Her breathing changed slightly, then settled into a steady rhythm again. Her orgasm had completely drained her. And mine had drained me, quite literally.

I drifted back to sleep.

* * *

In the morning I woke up on my side, almost as if I hadn't moved at all last night, but when I gradually opened my eyes Tara was no longer spooning up against me. I frowned, worried for a few groggy seconds, before I sensed a presence and turned to look up: Tara was sitting up on our mat, legs crossed, smiling down at me.

Smiling.

It was the most beautiful smile of the most beautiful woman I had ever seen.

"Good morning, sleepy head," she said.

I smiled back up at her, relieved to see her in such a good mood. I rolled on my back and felt the still air of the hut upon me. I was still completely naked, of course, but no longer with even the blanket over me. Tara actually had it draped around her shoulders, not unlike a shawl. It must have been to keep the last vestiges of the fading chill off her; it certainly wasn't for modesty, because the blanket was fully open in the front. I could very clearly see my sister's large breasts, her hard nipples pointing right at me. And, as I had mentioned, she was sitting cross-legged, meaning that with just the slightest lift of my head I could peek over her crossed legs and stare directly into her beautifully exposed vagina. Which made my smile bigger.

Among other things.

"I think you have to pee again," she said with a wink.

"What? Oh." Lifting my head a little more, I could see what I already felt, yet another erection.

But this time I wasn't embarrassed. This time, I was happy to show it off to her.

"It's not just because I have to pee this time," I said, allowing a little mischief in my voice.

"I hope not," she teased back without hesitation.

This caused a long moment of silence between us, both of us locking eyes for several moments. I may not have penetrated my sister last night, but something definitely had changed.

"Come on, husband," she said at last. Then with another wink and her cute little tongue sticking out, Tara shocked me by taking the finger and thumb of her right hand and applying a light gripping pinch to the shaft of my hard cock, just below the base of the head. "You need to take care of this so we can get started with our day."

Before I could react she was on her feet. She dropped the blanket and found another empty wooden bowl. I shook my head and grinned, then got to my feet, stretching and trying to work out the kinks of sleeping on nothing more than a mat and a few animal pelts over dirt. Tara handed me the bowl.

On only our second morning of "matrimony" we were already following a routine. But as our second night as "husband and wife" had progressed, so was our second morning, because this time my sister didn't bother turning away to give me a semblance of privacy while I went to the bathroom. She simply folded her arms under her ample breasts and watched with unmasked amusement.

"Really?" I said.

She shrugged. "After last night, after having to clean your mess up from between my legs, I figured being shy around each other was sort of silly now."

"My mess?"

"Okay," she blushed. "Our mess. Nevertheless," she gestured the entrance to the hut, "the natives grow restless."

Well, if she was going to be bold, then so was I. I hesitated only for a couple of moments, because I now really truly had to piss like a race horse. It certainly wasn't easy, facing off with my naked sister, trying to will my erection back into some partial degree of flaccidness so as to be able to aim into the bowl. Eventually, though, I got the aim lined up, and after a couple of piss-shy drops I finally got a good stream going, and it was a wonderful relief.

Halfway through, when I was more sure of my aim, I glanced up at Tara. She was openly staring at my cock as a steady stream of urine filled the bowl.

"It'll only be fair for you to let me watch you do this some day," I said with a mocking tone of annoyance.

She blinked, then looked up at me. "What? Oh...well, I suppose that's only fair."

Wow, I had only been joking. Did I really want to see my sister pee?

"Sorry," she said. "I don't know why I suddenly find what you're doing so fascinating. I keep resisting the urge to step around behind you to help you aim."

Wow again. It was surprising enough to cause me to stop peeing. My cock twitched.

She giggled. "Oops, did I embarrass you?"

I gave a nervous chuckle. "Not really, I was about done anyway." I gave my now fully flaccid penis another shake or two over the bowl, causing Tara to titter in amusement, then carefully set the bowl down. In another part of the hut I found another bowl still full of fresh water with which to rinse my hands, though I knew I'd be washing in the river again soon.

Turning back to her, I said, "So, shall we, Mrs. Staddon?"

"We shall, Mr. Staddon."

* * *

On this second of our three-day matrimonial ceremony, different activities at last took place. The men and women of the village went their separate ways again, but only as far as having one sex on one side of the river, the other on the other. For a short while there was a degree of mixing as everyone enjoyed an opportunity to splash and swim a little in the fresh water of the river. But at a single sudden command from Zami on the female side everyone quickly hopped out to the river's edges, segregated once more, and everyone dripping and gleaming in full nudity.

Near each edge of the river, directly facing each other, I noticed that surprisingly Western-looking chairs had been fashioned out of reeds, sticks and leaves. Guided by my "groomsmen," I found myself sitting in a high-back chair with honest-to-god arms, not unlike what one would expect at the head of an American dinner table. Tara had her own equally elaborate chair facing me from across the water. It was one of the narrower points, so I could clearly see my sister only about thirty feet away.

We smiled at each other's naked glory as the segregated tribe halves gathered around us. On my side the men began to beat their chests and strut around, chanting in unison. On Tara's side the women lined up along the edge of the water, laughing and gesturing teasingly, as if conveying to the men that they were no match for the strong Kasabai women.

From time to time Zami spoke, or small groups from either side would sing songs back and forth, dancing in very unusual but clearly festive routines. Between the distance and the sound of the river, it would've been impossible for Tara to translate for me in anything under a constant yell, so I just sat back and let the events unfold around me.

In truth, I was only interested in one thing: our third night together. As patiently as I could, I played the dutiful new husband and did my best to enjoy being the center of attention, along with my "wife," throughout the rest of the day's festivities, which included fine meals, fine singing, and of course more bathing. I was beginning to think the term Kasabai actually translated into "prune."

Then the evening, with all the incestuous pleasures it promised, came at last.

* * *

Back in the marriage hut, the scene was quite familiar: Tara and I stood side-by-side while Zami, facing us between her two nubile naked assistants, orated in her now-familiar "elder" tone, no doubt blessing we the happy couple, conjuring the gods of the lands to be kind to us, happiness to the village, that sort of thing. In a soft aside, Tara partially paraphrased the transition for me, but unlike the previous two nights she seemed to be less focused on Zami's words.

In fact, I was beginning to get the sense that my sister was growing impatient for some reason. She was shifting a little too frequently on her beautiful bare feet. We started holding hands, and her thumb moved back and forth regularly along mine. When I turned to look at her she seemed to be almost aglow, clearly charged by something. My heart swelled when a sudden thought came to me: was she as eager as I was to get to our third coupling? If the orgasm she'd had last night was any indication of what our sessions were doing for her, the answer had to most definitely be yes.

So I smiled, and my penis began to swell.

It didn't take long for Tara to notice this, and I now luxuriated without reservation in the fact that she was gazing very openly and wantonly at my growing erection. Without taking her eyes off it, she whispered to me once again.

"You're so beautiful, Cal."

Her tone was pure, full of emotion, I felt myself getting choked up a little.

Seeing my erection for herself, Zami seemed to hasten her words, and before long her young assistants were stepping toward us, gesturing for us to move to positions to which they guided us. This time I was the one who was encouraged to get down on the marriage mat first. The young woman guiding me spoke gently in Kasabai, and Tara translated.

"She wants you to lay flat on your back, Cal."

I followed instructions. At one point, as I was being guided down onto the mat, the tip of my erect penis grazed against the assistant's arm. She grinned in amusement when she realized what hit her, and I clearly could see a small moist spot where my precum had oozed against her smooth brown skin. I glanced sheepishly up toward Tara, but she was looking again at Zami, who began speaking once more. Tara translated:

"Tonight is the final phase of the union. We began with the Sun bringing its warmth and Light to the Forest. The next night brought the River flowing and nourishing its strength and Seed into the Forest. And tonight..."

Tara looked down at me, her eyes twinkling with emotion.

"Tonight the Forest finds its Root."

While I pondered what that meant exactly, my assistant moved from me and joined the other on either side of Tara. She was guided to approach me, and then to step over me so that her feet were on either side of my hips as she looked straight down at me. Were I to grab my cock and point it up toward her, it would be aimed directly at my sister's smooth moist vagina.

We stared at each other.

Tara's breasts looked heavy and massive from my current point of view, looking straight up toward her. They moved beautifully as her chest puffed in and out with deep breaths of anticipation. Her legs looked infinitely long, infinitely smooth. Her perfect pussy pouted proudly down toward me. I began to feel a slight tingling in my fingers and toes, as if every last ounce of my blood was now flowing toward my groin, desperately keeping my cock as hard and ready as possible.

The Forest finds its Root... The meaning of the translation was beginning to make sense. Assuming on all three nights she represented the "Forest," it was now pretty obvious as to what the "Root" was. In crude Western thinking, on our first night together Tara and I had done it Missionary style, and last night had been Doggie Style.

Tonight my sister would straddle me.

She seemed to come to this realization at the same time, and when I could pull my eyes from her beautiful pussy or various other naked parts of her body I saw her expression change slightly into one of logistical consideration: how would we go about simulating our final act of marital consummation tonight? The answer actually seemed fairly straightforward: she'd settle onto her knees over me, no doubt, and when the blanket was draped over us, she could simply sit upon my cock as it flattened against my stomach. Or to make it look like I was entering her, she could conceivably angle it to stick up against her ass crack, needing only to slide forward slightly to get the look just right. So tonight I would either be cumming against her ass, or my own stomach. Either way, I certainly wasn't going to complain. I only hoped at that Tara would allow me to use my hands, to hold her hips, perhaps reach up to feel her breasts...

As predicted, the assistants guided Tara to lower herself down. Tara kept her almond eyes on mine the whole time. We were lost in each other, now completely committed to our simulated roles as husband and wife. No awkwardness remained; we'd seen too much of each other, felt too much of each other. This third night was feeling quite natural. And as Tara sat upon me, my penis felt the now familiar sensation of her soft, warm vagina lips as they caressed gently along the length of my cock, which had indeed been pressed against my stomach, between her thighs.

This was going to be wonderful.

I moved my hands tentatively, grazing along the sides of my sister's legs. In our previous "couplings," my hands and arms had been used only for support and balance. Tara had gripped my penis that first night, speeding my ejaculation, but amazingly this was the first time I was attempting to explore Tara's body on my own initiative.

She welcomed it.

With her own hands, Tara guided mine toward her naked hips, and I gripped them with open lust. My expression at this point must have been that of a giddy teenager about to get laid for the first time, and Tara's face beamed with affectionate amusement back down toward mine. Her thighs and hips and buttocks became fields of exploration for my fingers. Smooth skin, toned muscles, pure woman. In return, Tara allowed herself to lean forward slightly, and she brought her arms closer together in front of her, causing her breasts to swell to an even larger size, capped by rock-hard nipples. At the same time she leaned gently against me, her hands on my muscular chest. She shifted her hips slightly, smiling at the gasp of air that escaped my lips at the sensation. The shaft of my penis, and even my testicles, were now quite moist by my sister's eager wet pussy.

Where was that damned blanket! I was eager to feel my sister begin moving over me, desperate to feel her up even more, and hopefully help her cum again before my own inevitable explosion. But after what both Tara and I realized had been several moments, no blanket had come. Something other than our sexual position was different tonight. But what?

The answer apparently came in the form of Zami speaking again, and while I had to wait for my sister to translate, I clearly recognized something unmistakable on her face: stunned surprise."What is it?" I whispered. I couldn't wait for the translation. Whatever Tara was hearing from Zami caused her not just to look surprised but to freeze her body in a clear fit of tension. It was frightening enough for me to refrain from any further groping of her naked body until I knew what the hell the matter was.

Finally, Zami stopped speaking, and Tara slowly looked down at me again. "There...there will be no covering tonight," she said weakly.

"What...what do you mean?"

She swallowed. "I...well..."

Movement in the hut caused Tara to pause and glance away from me again. I shifted just enough to see that it was Zami who was moving. The assistants had long ago backed away to the walls of the hut, once again watching the entire proceeding with open interest. But Zami was indeed moving again. Moving toward us.

She kneeled down next to us.

"Tara," I croaked, "what's...what is going on?"

Zami knelt down, and as she muttered yet another odd chant in Kasabai, she reached out toward Tara's hips. I slid my hands out of the way, quite confused. I looked back up at my sister, not even trying to mask my concern.

Tara, for her part, seemed to have regained some of her composure, the shock of what she'd been hearing Zami say finally settling down. She looked down at me and said gently, "Cal, Zami is going to bestow her final blessing upon us."

As Tara said this, I felt her begin to lift her weight off of me at Zami's guidance. I began to desperately wonder what in the hell this all meant. Was Zami pulling my sister, my "wife," off of me? This "elder" wasn't about to try to mount me herself, was she? Lord knows, I was horny enough at this point to hump a rough-barked tree trunk, but this was certainly not the setting I considered ideal in what was otherwise every man's fantasy: a threesome.

But there would be no threesome, as Tara explained: "Cal, as the chief elder of the village, of the Kasabai, Zami is going to personally bless and personally...guide us...in our final and most precious stage of marriage." She paused, then added, "She's going to...'plant the Root.'"

With that, she lifted herself off me completely, and I felt the warm air of the night on my glistening cock. I hadn't realized until that second how indescribably magical it had been to feel warm caress of my sister's groin on me. But then it was my turn to give a look of shock when I felt Zami's warm dry fingers begin to lace themselves around the thick firm shaft of my penis.

I opened my mouth to say something, feeling obligated to say something, but I was as stunned and amazed as that very first time that Zami had clutched at my flaccid cock and balls when I had encountered her before we had first entered the village. That seemed like months ago, though it had been only days. And at that time, though I was still quite nervous about being naked around my sister and other villagers for the first time, I had been otherwise relaxed "down there." Not this time. This time I was sporting the epic erection of my life, and it was now firmly in the grip of the elder of a strange and obscure tribe in the middle of an almost unknown corner of the wilderness. In fact, she was gripping me with only one hand. With the other, Zami was reaching up and touching Tara's shoulder. But she wasn't just touching Tara's shoulder. She was urging her back down. Directly down toward my cock, which, in the firm grip of Zami's hand, was now pointed straight up at my sister's vagina.

"Tara..." I was finally able to moan.

She had been slowly allowing herself to be lowered down on me, but with mere millimeters to go, Tara paused, and she placed her hands on my chest again.

"Cal, I'm sorry...I had no idea it would come to this."

I glanced at Zami, but the elder was surprisingly patient. For all she knew with her fractured understanding of English, Tara and I were simply expressing words of love and commitment to each other. I turned back to my "wife." When I spoke my voice seemed to be from a thousand miles away.

"Tara, I am not going to do anything you do not want to do."

"Oh Cal," she said. A tear formed around one of her gorgeous eyes, like a gleaming diamond. "You are the most wonderful, most important person in my life."

"And you are everything to me," I replied, my voice thick with emotion.

"So I tell you this with an open heart, my Cal," she said, her voice cracking with emotion, barely a whisper. "Enter me now, my love, and allow me to reward you with my very body, my very soul."

My love...

Zami pressed again on Tara's shoulder, and closer the two of us came, until we connected. Until I was at her entrance. Our eyes never broke contact, and as the diamond fell from my sister's eye, down upon my chest, her hips lowered down upon mine, and slowly the penetration began. And I entered her.

I entered my sister.

As my penis slid inch by inch into the tightness of Tara's vagina, Zami's fingers disconnected one by one, and in one long incredible fluid motion, Tara settled fully onto my hips, and her weight upon me became an extension of the warm blanket of pleasure that emanated from our combined cores. Continuing in slow motion, Tara leaned down fully against me, and as our chests came together I felt the added warmth and softness of her ample breasts.

When our faces got close there was no hesitation: we kissed.

Days of nudity, days of incestuous sexual tension, including mutual orgasms and various other bodily functions...yet only just now, in this perfect moment, was I kissing my sister as a lover for the first time. Our tongues intertwined and ours was a kiss as deep and as passionate as could be expected from any newly betrothed couple. It was such a whole and fulfilling and mind-numbly exquisite kiss I'd almost—almost—forgotten that I was inside her.

Until she moved.

Our eyes had been closed for the kiss, but as the sensational reminder of our coupling sent tingles throughout our bodies, our eyes opened simultaneously, and Tara lifted her head slightly, breaking the kiss only so she could look down upon me.

"So beautiful," she said, and she smiled. I smiled back.

We began making love.

Forgetting everything around us, forgetting the reality of our genetic connection and the world outside this hut, Tara and I moved slowly against each other. She raised herself steadily up and down, and as our hips met I pushed up, getting every last possible millimeter of my aching erection into her. Our movements became more pronounced, more eager, and my sister occasionally let out a gasped grimace. It was clear from the beginning that her vagina was not yet used to my much larger-than-average penis, and her cervix was literally feeling the brunt of it.

Amazingly, though, even though this was our first time having sex it was as if we'd been lovers for decades, because our rhythm never lost its steady stride. I'd never felt so complete and perfect inside a woman before, and Tara clutched at me as if to lose me from inside her would mean the end of her life.

We were only vaguely aware that our incestuous love-making was taking place under the gaze of other people. It didn't matter. Tara and I were lovers at last, and the rest of the world was now melting away as we melted together. Throughout the experience, we never really moved more than slowly, hips moving just enough, arms clutching tightly to each other, tongues continuously intertwining. I wanted it to go on forever. But of course, the laws of biology were beginning to take their toll...

I felt the rumblings of my orgasm. It wouldn't be long now. And Tara's tight vaginal opening clenched and unclenched around my shaft, her breathing became erratic, even coming out in quick staccato gasps...

My sister was about to cum, too!

It was incredible. It was too good to be true. I was about to experience a simultaneous climax with a woman I now loved more than anything else on this planet. But with that realization, I also suddenly became aware of other laws of biology: I was inside my sister, I was about to climax, and I was wearing no condom.

The thought of ejaculating directly into my sister's eager body was almost enough to push me over the edge for real, but I managed to slow our movements even further, scared to even bring up what had to be said. But as if she could read my mind—or more accurately, deducing why I had slowed our love-making to practically a halt—Tara made the decision for both of us.

"Don't stop, Cal," she whispered breathlessly in my ear. "I can't bare the thought of you stopping, baby, not now...not when we're both so close..."

"But—" I stammered, gasping as she began to slam her hips firmly against me, impaling herself even further on my cock. "But Tara...should we be careful? Shouldn't we—"

"It's okay, Cal," she almost shouted. "Don't stop, baby, please! I'm going to cum, and I want...I want you to cum too!" She began grinding harder, as if just that one more quarter-inch of cock was going to hit her spot just right. "Inside me!" she cried out. "Oh God, Cal, cum inside me, please do it!"

"Oh God, Tara!" I moaned, feeling my balls tingle and tighten.

"Oh, please do it, my love! Just let go and fill me!"

Her last plea was an all-out scream as she was now deep in the throes of clearly the most powerful orgasm of her life. And I was right there with her. With one final powerful thrust upward with my hips I buried my raging cock to the hilt and unleashed a torrent of molten semen. For a solid minute she wailed out in pleasure and I grunted like an animal, brother and sister cumming together. I felt rope after rope of thick, potent incestuous sperm blast deep into my sister's clenching pussy, and it only served to heighten her orgasm. Deep within her I knew that I had ejaculated harder and more powerfully than ever in my life, and throughout our mutual explosions of bliss I could only clutch desperately to my sister so she wouldn't fall off of me in her ecstasy.

After this exquisite session of long warm blasts inside her, I felt my ejaculations finally began to ebb. But as my cock calmed down from its own spasming twitches, I could feel the continued contractions of Tara's vice-like vagina. It was as if a fist was inside her body, clutching and squeezing my cock tightly, milking every last drop of sperm from the shaft. Beyond the copious moisture of our love juices flowing together at our groins, the rest of our bodies were wet as well. In such jungle settings, after such intense orgasms, we two new lovers were drenched in sweat. But we didn't care.

Tara's quivering pussy finally began to relax, and her breathing just started to slow, and in total orgasmic exhaustion she slumped forward again, onto my chest, her firm wet breasts squishing out again against me as I gripped her naked hips and kept her steady. We lay like that for several minutes, just breathing and basking in the afterglow. Out of my peripheral vision I could sense that the Zami and her wide-eyed young assistants had quietly exited the hut. Another few minutes passed, and it seemed almost as if Tara had fallen asleep on me. Amazingly, I was still almost fully hard, and still buried inside her. I flexed my groin instinctively and heard a slight subconscious gasp from my new lover.

I kissed her forehead and whispered instinctively what I'd come to realize over the last few days: "Tara, I am in love with you."

Though the words had barely been audible it was enough to stir Tara from her semi-slumber. She lifted her head and gazed directly into my eyes. She held herself like that, just staring intensely at me. Despite the situation—including the fact that I was still inside her—I began to feel slightly foolish. We had toyed with the "love" word quite a bit over the last few days, but now I was saying it directly: I was IN love with my sister.

Was it too much? No.

Because in the next moment Tara burst into tears and threw herself back against me, gripping my body almost painfully tight with her thighs, knees and arms. When she spoke through her sobs, her voice was muffled against my neck, but her words were clear:

"I am in love with you too, Cal. Oh god, how I love you!"

There was no ambiguity in the tone and language we were using with each other. This was far, far beyond the familial love between siblings. I had fallen utterly and deeply in love with my sister, and she was expressing the same toward me. I wasn't about to try to rationalize it or think about the implications of it. I only knew it was true, deep and absolute love.

Our new love was being consummated through continued caressing, kissing and, well, love-making! Though I was far from being as ramrod hard as I had been during our first round of sex, the novelty of Tara's unknown vagina, the pure eroticism of the incestuous moment, and my complete passion for this woman kept my penis firm enough to remain inside her. Our faces were so close that we could taste each next breath we exchanged in front of each other.

Eventually we did move, had to move. Tara's frame was quite slender and light against my thicker more muscular body, but a person can only hold a position for so long! As I moved to roll my sister under me, she maneuvered her legs to keep us together, her heels now digging right into my butt cheeks, keeping my perpetual erection firmly inside her. When we made it all the way around we ended up in the classic missionary position, and it was clear what need to be done: I started pumping again.

I drove my tongue into my sister's mouth, and hers entwined right back into mine. I moved back and forth, in and out, steadily pumping my once again fully engorged penis deep into Tara's eager opening.

"Jesus, Cal," she said, her voice shaking and breaking as my hips pushed against her, "you're so big...oh how I've been craving you!"

To this I could only respond by thrusting harder, more desperately into her. Having climaxed mere moments before I was more relaxed, more confident, and much more determined to give this beautiful woman the ride of her life, and I fell into a steady solid rhythm of fucking. Tara continued to moan and gasp and occasionally cry out as each next orgasm began to build, crescendo and then crash over her, filling her body with a feeling I could only imagine yet fully appreciate as something I, her own loving brother, was giving her.

I can only imagine what the villagers were thinking as the minutes ticked by with the constant sound of my sister orgasming loudly from within the tent. For the most part the sounds from her throat were unintelligible syllables of ecstasy, but here and there her words were pure:

"So good, Cal...oh, my sweet brother! Yes, baby, make love to me! Give it to me! Don't ever stop, my love!"

And I didn't! Well, I mean I kept giving it to her as much as I could, as hard as I could, until the essence of what we were doing began to creep up on me again and I began to feel the tell-tale sensations from deep within my groin, deep within my core: I was going to cum again.

Inside her.

Having let loose inside my sister the first time, there didn't seem to be a need to warn her this time. On the contrary, as soon as my writhing and bucking lover began to sense my rhythm breaking, my breath coming short, she opened her eyes and began to encourage me.

"Cum for me, my love. Let yourself go."

I clutched her desperately as my orgasm built up, and once again I felt her heels dig into my ass, beckoning my climax.

"Give it to me, baby. Cum inside me, please!"

It was going to happen soon.

I grunted, "Oh Tara, my sweet girl, I can't hold back, I can't—"

"Yes, my love!" she cried out. "Cum for me! I love you so much, and I want to feel you explode inside me!"

That was all it took to send me over the edge. What man can resist the words of a woman practically begging him to ejaculate inside her? And that's exactly what I did. After giving her a few last monstrous thrusts, sliding us half-off our reed mat, I finally slammed home against her and roared out once again in ecstasy as I unleashed yet another voluminous torrent of semen into to Tara's perfect pussy.

My sister received my seed and my love as eagerly as I gave it; I felt her clasp me even tighter, screaming out, "Yes! Yes! Fill me, Cal, yes!" There could be no mistake by anyone in the village—hell, anyone in the whole fucking jungle: this "marriage" was CONSUMMATED!

Now it was time for true exhaustion. We couldn't have kept going if we'd tried, and as if to confirm what needed to be a rest period, I felt my penis slowly deflate and soften at last. I looked down at the woman below me, the woman I'd grown up with as a sibling and now knew as a lover, as a "wife." She was absolutely glowing.

"My god, you are so beautiful," I said.

She giggled, causing us both to wince in "pained" pleasure as her vagina contracted and involuntarily expelled my flaccid penis from her body at last.

She said, "If I'm as sweaty as you appear to be, I'm sure I'm a horrid mess."

"You are beautiful," I insisted, giving her sweaty nose a light kiss. "You're perfect."

"And you are like a god, Cal," she said softly. "I want to worship you, I swear."

"Oh, baby..." And we kissed again, for several moments.

Eventually Tara eased back, breaking the kiss. She said, "I'm sorry, baby, but as much as I want to stay like this with you for ever, I'm actually starting to cramp up."

I feigned a moment of pouty resistance, realizing I had this slender lovely girl locked in my embrace, but I too was feeling quite stiff and gooey from our epic love-making, and it was actually nice to be able roll off of her and lay next to her, catching my breath, resuming a normal pulse rate.

I must have dozed for a few minutes, but Tara's sudden gasp of "Oh my god" got my eyes wide open again.

"What is it?"

She was sitting up, looking down at her crotch, her legs spread apart. She looked...hot!

"You came like a fire hose, Cal," she giggled, staring down at herself. "I'm going to be leaking for hours."

I grinned. "You should have expected that."

She glanced at me, then grinned herself. "That's right. That first night when you came on my stomach, my god! You can really pump it out, baby!" Hearing my sister talk about my cum actually got my cock to twitch, ever so slightly. Tara actually noticed it, then reached over and put her hand over my crotch, as if to block another erection. "Oh, no you don't! It's going to take me a while to get used to that monster, don't even expect a Round Three tonight!"

"Don't worry," I said, "I promise not to rape you again until the morning."

"It's me who's going to do the raping," she quipped back.

It was incredible. Here we were, bantering and flirting and joking like excited new lovers. Well, we were new lovers, but certainly the two most unconventional lovers anyone could possibly imagine outside of this backward jungle: two blood-related siblings now married in the eyes of the community in which we had integrated ourselves. I must have been really daydreaming about this, because I suddenly noticed Tara just staring at me, smiling.

"What are you thinking right now?" she asked.

I shook my head and smiled back. "Only how incredibly lucky I am."

She moved toward me, shifting to her hands and knees to lean in and give me another kiss. "That makes two of us," she whispered. "I could never have imagined that—oh!"

She suddenly looked down between herself again, and I followed her gaze as a large glob of my semen chose that moment to ooze out of her still-swollen, onto the reed mat.

"Like I said," she chuckled. "I'll be leaking for hours."

"Why don't we rinse off before bed," I suggested.

"A wonderful idea!"
