Krissy pressed down her weight on top of the smaller Narissa as she grabbed her head in both hands and nibbled her neck. The smaller reptile was a blush of teal scales and hissing moans of pleasure, her new and larger fantasy girlfriend almost instinctually driving her insane with anticipation as the buffer lady lizard held down her arms and chewed at her sensitive underneck before releasing a slick a warm tongue from her snout to lick at Narissa's nipples with firm and controlling slurps of her mighty tongue.
Narissa was in heaven. She struggled against the fantastically strong femme reptilian and cried out as the huge and powerful creature resisted her struggles with ease, her mass of thick powerful muscularity easily pinning the smaller reptile down as she worked her tongue over Narissa's breasts and sensitive belly. She simply laid back, closed her eyes, and let her new mistress do what she wanted, for the first time in her life reduced to a sexual plaything according to the female hierchy of her species. Krissy was impossibly big and strong, far beyond the normal limits of her leaner reptilian species, and having her fantasy brought to life so wonderfully lubed her like nothing else ever had.
As Krissy continued downward, forcing Narissa's trembling arms behind her back and holding them tight, the bigger lizard growled and hissed, her new stronger senses enticed by pheromones and the smell of their joint female arousal, the unique scent and even flavor of Narissa's particular sexual scent driving her to greater and greater need. She would pleasure the smaller lizard woman completely until she begged for it to stop, and then she'd keep going. That was her need, her desire, her will. Distantly, the human mind in Krissy was titilated by the transformation, her new size and power, and she almost wished to become even bigger and more dominant for her beautiful new partner, but this would do for now.
Ty stood in the door frame watching the show with the hardest cock he had ever had. His masculinity felt pathetic before the two gasping and writhing lizard women, and he looked down with a hot blush at his own inadequete body, denied the healthy development of his age by his own genetics. He wanted to please Narissa. He wanted to gain the confidence and sexuality to fill the ancient lizard woman's sex and bring her to a satisfying climax. He knew there was only one way to achieve that level of satisfaction for them both. But he was scared what might happen.
As the girls progressed their fun, Krissy held down Narissa's stomach with a powerful hand and forced her legs open. Of course part of the game was that Narissa pretended she didn't want it, and despite her struggling and whimpers of protest against the larger lizard girl, it was all to heighten the mood of dominance and increase her own pleasure. Krissy lowered her muzzle to Narissa's practically dripping pussy, held her thighs open, and tenderly licked her huge tongue down the length of the scaly slit, teasing the swollen pink clit within and lapping Narissa's thick clear fluids up.
It seemed that Krissy was growing bolder, more confident in her new form, and any suggestion of a human being passed as Krissy plunged her hungry snout into Narissa's slit and began lapping her juices up as quickly as they flowed forth, forcefully pinning her down the entire time and taking what she wanted. Narissa squeeled, writhed, and gasped, offering a weak and pained "No!" and gasping "Stop!" from time to time. Krissy was fully engrossed in her task, however, and relented nothing. Even as Narissa came the first time, her tail flying stiff and her tensed and powerful reptilian body flailing wildly under the giant's powerful attention, Krissy offered no sign of stopping, forcing Narissa's clit to bulge and strain again towards another climax.
Ty took a deep breath and took advantage of the distracted women. He started slowly, working his power over himself and simply feeling what it was like. From within himself, a deep and powerful energy began to build through his flesh. He could feel warmth and strength like nothing before.
Somewhere, distantly, lost in a fog of physical sexual delights she could never have imagined, Narissa felt Ty. She briefly closed in on his thoughts, delaying her own impending orgasm for a mere shred of a second, and experienced his perceptions - delicious and warm - of experiencing his own abilities in full. Narissa offered a satisfied smile, eyes clenched shut in bliss, as she fell over the cliff a second time from her big sexy girlfriend's tongue and passed into a state of screaming, hissing, and powerful multiple orgasm. Her claws dug into the floor with such force she tore the cheap carpet and splintered wood, her pinned legs strained and kicked with no purchase. Her body trembled with pure focused lust. She felt for a moment her bladder might release from the intensity, but then realized it was just Krissy's thick forked tonguetip slipping into her pussy and hitting her reptilian g-spot.
Ty felt Narissa for a moment and built up his courage. Amidst the lizard sex, the bestial growling, and the scent of horny reptilians and their fluids, Ty progressed his body to its proper development. He was not disapointed. Falling back into the door frame, ass planted on the ground, he struggled and groaned as his own boiling hot energy changed him. It was almost overwhelming, and he had to keep stopping to prevent himself from passing out. With each development, he took a moment to wipe the tears from his eyes, check over his progress, and marvel as he became a proper young man of 15. He began to exagerate, giving himself athleticism and definition. He grew harder and taller, approaching a lean but muscled 5'7" and a thick and healthy 5 inches long downstairs.
As Krissy began to make Narissa beg, as she had intended, Ty continued to grow off beside them. The entire trio was now so lost in lust and pleasure that they didn't hear the lock click downstairs and Dustin's keys jingle as he turned the knob.
