After a long search Jeff was tiredly looking at the computer screen slowly scrolling down through the options as a result of his boredom, then Emily spontaneously pointed at the screen, "that one", she excitedly yelled, pointing at an option named animal cloaca, it has a ton of varieties and modifications that the user could customize, Emily went for that option since she loved reptiles and all from them, the idea of having a reptile genitalia just made her wet, so after checking some options and adding some extra things they clicked enter and waited for Emily's changes.
Jeff saw his friend standing up naked in front of him just wearing a shirt that could see her nipples through it since she wasn't wearing any bra, after some seconds the vore and reptiles lover girl felt the changes began in her body. Her feet extended, turning her nails into long black claws while her legs also morphed into a dinosaur-like legs, green scales didn't take too long appearing in all her feet and extended to her legs and hips, replacing her human skin from waist down to green lizard scales, then something started to grow on the top of her ass becoming larger and pointed that resulted in a lizard tail. Her changes weren't finished as Emily still had her human vagina and asshole, but then another hole appeared, moving her other two holes closer to her tail, now her changes were completely finished, a human girl with the lower body of an anthropomorphic lizard which had a reptile cloaca and human vagina and anus at the beginning of her tail.
"This is completely awesome" Emily excitedly said trying to keep the balance with her new legs.
"Sure it is, I see that you didn't have enough with the cloaca part" Jeff giggled noticing her lizard legs and tail.
"It was an opportunity that couldn't ignore" she put her hands in her waist, now standing properly. "And by the way", she added, "now we can have more fun" she rubbed all her three holes with her tail.
"And I'm totally looking forward to it" he approached Emily.
"So what should we do now" she said in a sensual tone putting her hands in Jeff's shoulders.
