Through my travels in the Kalos region, as a Pokemon scientist and Pokemon breeder, I had recently discovered an unusual potion shop, which carried elixirs and tonics that enabled a person to temporarily undergo transformations into various Pokemon, including some new potions from the Kanto region which enabled even more powerful Pokemon transformations. I was too intrigued, I had to investigate. I went to the shop and decided to try the Charizard tonic, infused with a fast-acting plasmid containing Charizard DNA. I purchased the bottle and went to a secluded clearing not too far from my house, bringing the bottle of Charizard DNA-infused potion with me, excited to find out how effective it was. I was waiting on my wife, Kateri; she was curious about the potion as well and wanted to see how the results came out.

I figured taking off my clothes first was a good idea, so I took them off, shivering a bit in the wind. I drank the potion and felt the changes begin. First, I began to grow taller. As I grew, I could feel my muscles tightening and becoming larger, and my hands and feet started changing into claws. A tail began to extend from the base of my spine, and my skin began to shift to a bright orange, my chest becoming ivory-colored. Within a few minutes, I had orange and ivory scales covering every inch of my body, and my hair had been absorbed by my scalp, leaving two straight horns, and my neck began to grow longer. As my neck grew, my tail continued to grow, a small flame igniting at the end, and I topped out at my max height of about six feet. I felt my skull begin to rearrange itself, and my nose and mouth elongated into a snout. I gasped as I felt two powerful wings burst from my shoulders, my wingspan quickly growing to six feet. The flame on my tail intensified, becoming bigger and brighter, and I knew my transformation was complete. I couldn't resist, and I leapt into the air, using my wings to gain altitude quickly, and then glided blissfully around the clearing, enjoying my new body.

I looked down and saw Kateri walk into the clearing and looking up, her eyes became big and round seeing me flying above her. I glided down, stopping just short of her before landing softly, feeling completely in-tune with the flight ability of my body. Kateri came close to me, her eyes still round in surprise and wonder, and she ran her hand over my scales, fascinated by the smooth reptilian feel combined with the warmth of my body. As she continued to slide her hand over my chest, I felt myself becoming warmer and somehow more relaxed, and slightly horny. I wondered what it could mean, but Kateri answered my question with an "oh wow," and I looked down and saw in shock my penis extending from my new sheath, growing quickly to become 8 inches long, a couple inches thick and a deep red color. Kateri looked up at me, amused and intrigued, and she couldn't help herself as she ran her hand slowly along my warm, red member. I felt the warmth intensifying, and I knew I was getting hornier. I nudged her breast with my snout, giving her a sly look and winked at her. Kateri understood what I meant, smiling back at me, and wasted no time in removing her shirt. Her beautiful E-cup breasts bounced free, so big and beautiful, one thing I really loved about her. I kissed her gently and began to fondle her with my claws, slowly so as not to hurt her, and continued to kiss her. I finished one particularly deep kiss and slid my tongue out of her mouth, down her neck and to her breast, and encircled her perky nipple with my tongue, licking, teasing her. Kateri sighed, feeling more relaxed. "Mmm, you're teasing..." she moaned softly to me. I growled softly in response, and gently took her nipple into my mouth and began to suckle her, applying just the right amount of pressure and attention in short licks with my tongue to make her whole body shiver in excitement. I took my knuckle and felt her vulva, now wet with her tasty juices which I knew from experience were addicting. I gently picked up Kateri in my claws, bringing her slowly to eye level. I smiled at her and gently spread her legs, bringing my nose close to her lovely vulva. I slowly extended my tongue, touching her clit with the just the tip, bringing a soft sigh from Kateri, before pushing my long tongue firmly over her sensitive clit, up and down, slowly evoking more moans from her as I stimulated her most sensitive organ. I continued to lick, extending even more of my tongue up and down her entire opening, making her moan even louder, her opening becoming slicker and tastier, arousing me even more, my cock becoming harder with every sweet moan she made. I slowly trailed the whole length of my tongue over her clit, before sliding the tip inside her opening, and firmly pushing the rest inside, making Kateri gasp as I slowly began sliding my tongue in and out of her delicious depths. I smiled even more broadly as very quickly, Kateri cried out in ecstasy and orgasmed, her whole body shuddering in pleasure, and she panted as she squirted her delicious juices into my mouth, her clit becoming even harder as her walls contracted around my tongue. I slowly slid my tongue out of her, dripping with her tasty fluids. Before she could fully recover, I brought my fully-erect cock to her entrance, already a foot long, and three inches thick. I slowly pushed my cock against her clit, making Kateri moan in surprise and sensitivity, her clit even more sensitive than before. I sat back on my haunches and grabbed her legs in my claws, so easy with my new muscles, and slowly penetrated her, my cock sliding easily inside her, until only a few inches were not yet inside her. Kateri panted from the pleasure of the penetration, amazed at how much bigger I felt, and grabbed my arms as I began to thrust, gently hitting her cervix with every push. Kateri began to moan even louder, her moans making me even more aroused every passing second. I brought my face to hers, and we kissed, my tongue sliding inside her mouth and entwining with hers. The pleasure was so intensely wonderful from being inside her tight vagina, and I began to get close. I grunted as I was almost to my climax, and pulled her tighter onto my cock. Kateri gasped as I penetrated her cervix, and I threw back my head as I orgasmed, and released spurt after spurt of my hot seed into her womb, making her gasp as I began to fill her up with each jet of my thick cum, her womb filling up and making her stomach inflate as the sheer volume of my cum stretched her womb. Kateri tried to hold on but the warmth filling her insides was too much, and she cried out in pleasure as she cummed hard, her pussy contracting hard around my cock, milking every bit of cum from me, filling her completely. Kateri belly was so big and round, she looked so cute and pregnant as we finished together; she was panting hard from the intense bonding session we had just had. She looked down in amazement at her huge belly, and I slowly pulled out of her, my cock flopping down as cum began to gush from her pussy, covering the ground. Kateri sighed happily in relief as her stomach slowly began to deflate, and I took the opportunity to surprise her and slide back inside her; she let out an "OH!" of surprise as my huge cock penetrating her soaked vulva, spreading her apart once again and burying my cock inside her warm, gooey depths. I quickly slid in and out of her, making sure not to apply too much pressure to her cervix but firmly sliding in as far as I could, and before long she was crying out in pleasure, getting louder as she came closer and closer to another climax. In only a few seconds, she let out a soft cry of ecstasy as her body went into overload and she came, her pussy contracting around me again, her body wracked by pleasure from feeling me inside her, completing her. Kateri had always been a busty cutie, and I grabbed her big breasts, so soft and squishy and I kept thrusting. I knew my wife all too well, and gave her little time to recover. "You're so mean! OH!" she moaned as my cock slid inside her almost to the hilt, thrusting quickly and firmly until in only another ten seconds she hit another orgasm, my cock still completely hard inside her pulsing depths. I kept pumping, enjoying making her orgasm multiple times, and she moaned even louder as she came only a few seconds after her last climax, her vaginal walls contracting wildly around my cock.

It was then that her changes began.
