It seemed like it took forever, but eventually Anne and I reluctantly broke our kiss. She hissed her affection for me and her soft tongue tickled my ear as she grinned. I couldn’t believe what I was staring at. Anne’s face and head were that of a boa constrictor, but from the neck down she still had the body of a human being. A scale covered green and yellow human body, but it was still recognizable. She watched me with interest, flicking her tongue, as I rubbed her arms and wrapped her large flippery hands into mine. It was as if there was no bone at all in them anymore. Anne grinned and rubbed her flippers against my chest, her eyes sparkling with excitement.
She grabbed the bottle in her flippers and handed it to me enthusiastically. “More!” Anne rasped, “Give me more of the oil! I want to see if it changesssssss me again! Thissss feelsssss ssssssooo good!” I grinned. “Does it?” I asked, emptying a healthy dose of the oil into my hands, recognizing the scent as the same my girlfriend now had. The smell of a reptile. “Yesssss!” Anne said, grabbing my hands and touching them to her ample breasts. “My blood isssss cold! My body isssss sssssooo different! More! More!” I gulped, and began to rub the oil into her tits, watching with amazement as they seemed to balloon under my touch, gaining firmness and size, stretching with an audible noise. Anne hissed her delight, and grabbed the oil from me.
“Fassssster!” She commanded. I complied, rubbing the oil into her growing breasts and spreading it to her body. I enjoyed the feeling of stroking and massaging her new scales, covering her from her head to her flipper feet. In no time, her smooth green and yellow scales with slick with the strange substance. Her eyes went wide with surprise. “I feel the changesssss again! T-They’re getting sssssstronger!” With shock, both of us watched as Anne began to gain size. A tiny nub of a tail emerged from her spine and quickly grew out from her rump, getting longer by the second. At the same time, my girlfriend gained feminine muscle and body definition as she enlarged proportionately, growing into a bigger and more lovely snake woman. As her tail dangled over the edge of the bed and reached the floor, I noticed her snout push out longer, saw her neck elongate to a full foot in length, and her torso stretch up ever so slightly as her midsection and thighs gained a little bit of plumpness to them. She was huge, muscular, and gorgeous now! Easily 8 feet or more!
“Mmmm!” She licked her lips. “Thisss makesssss me ssssso horny!”
I looked down and saw her engorged and pulsing labia, surrounded by those sexy scales. I couldn’t resist any longer as my penis erected. I had to have sex with this gorgeous reptile!
