Xan came again, his grossly swollen balls pumping his seed so hard they pulsed visibly before swelling larger still. Coal clenched her inner muscles around the growing member within, milking it of all it had to offer as her body simply absorbed the seed into her body. She had started to chant softly as she gyrated on her pole of flesh, uttering spells that came to her out of a lust soaked mind in a language she had never heard before, but that all demons, even minor familiars knew from the twisted womb.
“Ah, mistress, I think that the demon you were fucking may have…arg…filled you with a lot more of his essence when I hit him than he had …ohyeah…intended. Must have been some grade…A…spooge.”
“Then if he returns, I’ll have to…milk him of his seed again…He was certainly…more demon than…you could ever be…even if I…ah! Oh my, that’s what I’m here for…”
Xan’s musings were cut off by another bout of growth. He was now close to five feet, taller than he had ever dreamed and looking more like a real weight lifter than a child on steroids, but his penile growth had obviously dwarfed that of his body, and showed little sign of abating. Coal was now able to lift herself up and slam down on Xan’s rod in a most satisfying manner, Xan’s monster balls forcing his short legs apart so they could rest on the ground. Each downward thrust was met with a burst of hot seed, the pressure helping the buxom demoness lift up again, her wings fluttering in delight as her breasts bounced and her tail flickered across the stone floor.
As Coal continued the glow in her eyes gained power and her muttered incantations came faster and faster, more certain of the cryptic words and unhuman inflections. What had started in Xan’s ears as “grow you little worm” was too fast and mysterious for him to understand, but he doubted it had anything to do with him anymore. What little power of though he retained why fulfilling so many of his dreams was gibbering to him that Coal was defiantly more succubus than human, and that perhaps this was a bad thing for Xan in the long run. His senses too weak to pick up anything odd, Xan still suspected that somthign had gone wrong in his potion (well, more wrong than he had hoped for)…or was it Zyrix's botched spell that had lent the succubus in Coal more strength that two potions could have…
Conscious though on Xan’s part fled as his member suddenly switched into overdrive as Coal rose up onto the tip of his member, only her muscle control and Xan’s bulbous cock head holding her there as his balls clenched one last time, pumping a continuous stream of spunk in the waiting demoness’s womb, the final phrase of her spell ending in an orgasmic shriek of pleasure. As Xan’s balls deflated, the suction pulled them into his body as every last drop of maleness was pulled from him, fuel for Coals final ascension into demonhood. Slowly at first, but with increasing speed the extra hight he had gained was lost as his member grew even longer, if thinner. Soon the length of his rod had Coal on the tips of her daintily clawed toes, then floating off the ground using her wings as the shaft she was on grew still taller, as she had planned.
Soon, even Zan’s two foot height was lost as more and more of him was sucked into him member until all that remained of him was a five foot rod of rigid red flesh an inch and a half across, the purple veins along its length a parody of scrollwork. As his head was suckewd in to form a bulbous, fleshy ball at he flesh staffs tim, Xan’s last thoughts were: I was used… I was used!
