"I can't for the life of me understand why I'm being so nice to you, Saur'ex!" I exclaimed, gasping with delight, "after the way you doubled crossed Gyn and me!"
"But Linzi, haven't we already been over this?" the Snake-demon replied "How could I refuse he who was my Captain during The Great Cataclysm, the Second Father to my son?"
I moaned loudly, my vaginal walls squeezing and relaxing on his cock, feeling its unusual coolness inside me, as I basically rode his tail like I was straddling a horse, my bottom bouncing up and down on his huge ballocks, something I knew he enjoyed immensely. His leathery, tendril-like appendage gripped my ankles as usual, keeping me from falling off, as he rose upwards, extending and straightening his tail out beneath me. I wrapped my arms around him and spread my thighs wider apart so his thick shaft pushed deeper inside me, his cockhead pressing against the front of my vagina as the thick stem arched harder. I contracted my inner muscles more strongly, then relaxed them, building up a rhythm on his gorgeous iridescent cock, milking him with my body as he hissed slowly and loudly in deep pleasure.
"We're just too sexy for this little hu-woman to resist, father!" said Rept'ex, who had been using his own tendril appendage to whip my ass lightly, but who now began to slowly push the cool, smooth head of his equally rigid, equally impressive cock into my bottom, making me pant with joy as I felt both hard cockstems rub against each other and fill me tightly both in the front and the back. His leather 'second tail' now wound round my wrists, lifting them above my head and drawing them tightly together. I was now trapped and squeezed between both Snake-demons as they brought me slowly to panting, groaning, screaming release. They then wrapped me in their coils, one on each side of me, almost up to my breasts, my hands free as I sucked on one of their cocks, then the other, my fingers round the thick bases of each, pumping the iridescent shaft of the father's while my tongue flicked at the emerald green head of the son's, exploring the ridges and sensitive frenulum area with my tongue tip and my little stud, then sliding my lips over the cool smooth surface of the bulb to suck slowly. Then I would seal my lips behind the cap of the father's cockhead, tightening them on his shaft and sucking, while I slowly stroked and pumped the thick shaft of the son's, finally watching in fascination as both cockheads spat long, green, thick strings of cold Snake-demon come simultaneously.
Later that afternoon, as I wandered back from the Snake-demons' pit-like dwelling in the centre of the estate, through the pleasure garden that my Master had set out for me, to the main house, I reflected on how my sexual nature had developed since my beloved Gyn had brought me to the Demon Realm. Sexual activity was becoming less and less about physical pleasure for me, incredibly intense and enjoyable as that was increasingly becoming, but more about a deepening sense of satisfaction and pleasure in the performance of sexual acts for their own sake. My sexual curiosity was continuously getting the better of me, causing me to experiment with some unlikely household objects, as well as constantly exploring Tel'estar's toy chests for devices that I hadn't yet tried. I had been easily aroused from the moment of my transformation, but the sweet lickerishness in my belly had recently become an ever present tickling within me; I found myself unconsciously watching the crotch of every He-demon I encountered, assessing their probable length and girth from the outlines of their cocks through their garments. I had become such a nuisance in this regard that my Master had finally ordered me to stop seducing his staff after finding me in a barn with two of his Lynx-demon groundskeepers that I had made friends with during my captivity on his estate!
I entered the house through the main door, heading for the bathroom. I passed the open door of my Master's study on my way, spotting me, he called to me to attend upon him. Despite my captivity and my enforced separation from my beloved Gyn, he and I had been together so much by this time that I now actually accepted his Mastery over me; I smiled as I ran to where he sat, dropping to my knees and coming to a sliding stop before him, making him laugh softly.
"And what has my little pet been up to all morning?" he asked, smiling.
"Visiting the Snake-demons, Master!" I replied, gasping lightly, sexily, something else that I had begun doing recently whenever I found myself near any attractive demon.
"I expected as much!" he replied "Apart from myself, they seem to be the only ones who can...satisfy you properly these days. I have been giving that fact some attention lately, to be frank."
"I have just been thinking about it myself, Master!" I replied, again in a breathy, sexy gasp.
"At first I suspected that Lal'estel's evil had left some kind of residual traces in your nature." he continued, "but as the changes in you began prior to your encounter with her, I decided to consult the Demon Lore. I could only theorise, as there is no direct correlation with your specific situation, but I believe my conclusions to be sound."
"Yes, Master?" I asked, curious now.
"Gyn combined your natures at the time of your transformation, correct?" he asked.
"Yes, Master." I answered.
"And your natures are now melded, each one bound to the other, what you Hu-mans call 'soulmates', yes?" he continued.
"As I understand it, yes, Master." I replied.
"And my sister continued to infuse you with her essence, to rejuvenate you, prolong your life?" he added.
"This is true, Master." I said.
"And, of course, Gyn and I reformed your body by combining all of our essences." he concluded. "I did mention the possibility of unforeseen effects, did I not?"
"Yes, Master." I replied.
"Then there is only one hypothesis that fits, consistent with our lore," he concluded, "but will you trust me to test it on you?" he requested.
I needed to know as much as he did! "Yes, Master, do whatever it is you need to do." I said.
He grasped my left hand and, unsheathing his long dagger, sliced it across my palm! I screamed aloud, looking at him in pain, shock and disbelief. But then he held up his own left hand, palm open, revealing that his own hand was also bleeding, a sliced cut of the same length on it! He spat thickly into my hand, then rubbed it with his fingers until my cut was completely healed and had disappeared; his own hand he simply bandaged.
"Forgive me, Linzi." he said , in a tone that seemed to suggest he was asking for my pardon for far more than just a cut to my hand.
"What does that mean, Master?" I asked.
"First, it means that you are no longer required to address me as 'Master', nor must you refer to yourself as 'the pet', or any other variation of that description." he said, releasing me from those commands. "It also means that you are free to leave at any time you wish, although I humbly request that you remain here as my honoured guest until such time as I can arrange your safe return to Lady Gyn'estar."
"But what does it really mean, Mas... I mean, my Lord Tel'estar?" I asked.
He smiled at my politeness. "It really means, Linzi, that we should have paid a little more attention to Demon Lore!" he exclaimed. "We have inadvertently made a little demon out of you!"
I sat back on my heels, dumbfounded. "I...I'm a demon?" I stuttered.
"Well, a part-demon, more accurately, but not fully hu-man any more, definitely." he said, "no demon can now do you harm, for instance. Exactly how much of a demon you are, I am not sure, to be honest."
