Jenn stood back and hungrily looked Jill over. She was sitting back down and panting heavily, with an ecstatic look locked on her face. The area around her pussy was definately not clean shaven anymore - fine white fur had sprouted there and now covered roughly all of her crotch. Jenn could also see Jills tail protruding behind her, sticking up awkwardly from her sitting position. Jills tail was just as long and bushy as her own, but the colours were different - it was all white except for a black tip. Jills fur extended a few inches down her legs, but the change was definately concentrated around her pussy. Jennifer knew she couldn't leave her friend halfway through a job, so she took Jills head in her hand, saying "It's your turn to do me now."
A glare flashed in Jills eyes, and she replied "Nuh-uh. You only dared me to let you eat me out, you never forced me to do anything to you."
Jenn was lost for words, floundering wildly until Jill continued "Luckily for you, I'll throw this one in as a freebie."
Jenn laughed out loud with relief, "Oooh. You'll pay for that."
"Now now," Jill replied, "we've done me. It's your turn now."
Taking Jennifer by surprise, Jill launched herself forwards, wrapping her hands around Jenns ass and thrusting her face deep into Jenns slit. Jenns response was immediate, moaning in pleasure as she felt Jills tongue explore inside her. She placed her furry hands on the back of Jills head and they pushed themselves together. Jills tongue probed Jenn furiously, and Jenn was pleased to see that now both their tails were thrashing in pleasure. Jenn shuddered her first orgasm, hearing soft moans coming from her pussy as Jill was covered in her delicious juices. Jenn found that once she had started she couldn't stop, orgasm after orgasm bursting forth as she writhed in pleasure. Jills face was completely covered in Jenns thick juices, and she could feel the juices begin to work their change. Her nose and mouth pushed out into a small muzzle (much to the delight of Jenn). Her ears became pointed and furry, slowly moving to the top of her head. Her tongue got longer, and Jill exploited the opportunities this gave her, causing yet more orgasms to gush forth from Jenn. Jill could feel her hair grow longer and yet merge with the fur emerging on her face, forming a long black mane. She felt fur spread down her neck and onto her shoulders, following the paths formed by the juices dripping from the rapturous Jenn. Finally, after one more shuddering orgasm brought forth yet more of Jenns cum, Jill withdrew. She noticed with interest that the places where the few stray drops had landed also sprouted white fur, resulting in small dots of fur on her otherwise human midsection. Altough her head and groin were now that of a fox-woman, the rest of her was essentially human. She knew how to change this though, and took action while Jenn was still recovering. Gathering up the thick cum trapped in the fur around Jenns slit (doing this didn't help Jenn calm down at all), she watched as her hands grew black fur, her nails lengthened and sharpened slightly, her hands overall became more paw-like. Pleased at this development she spread the cum up her arms, sighing with sensation as they became more slender, and as fur emerged to complete her black 'gloves'. She eagerly connected her arms with her fur covered shoulders, and, pausing only to collect more of the liquid, kept going. Jenn happily complied with providing more cum, the sight of Jill massaging herself into a fox-woman had already led her to start masturbating with arousal. Jill massaged the cum into her breasts, dusting them each with a light coat of fur. She lingered pleasurably as each stroke caused them to swell to a surprisingly perky D size. The intense pleasure of oiling up her breasts with come brough Jill back to orgasm, and after she calmed down for a few seconds she noticed that her feet had grown fur where the drops of her own cum had landed. Excited with this prospect, Jill began frantically masturbating; exploring her now-furry pussy with her now-furry hand. Somehow she still had more cum left to orgasm (the small part of her mind that was thinking rationally at this point figured fox-girls must have amazing sexual abilities) and with her free hand she spread her juices around. First she connected her groin to her breasts, completely covering her chest in white fur. Then she spread her cum down her legs, making them more slender and covering them with white fur, until it became black 'socks' at her feet. These too changed, becoming more pointed like Jenns, and raising so they no longer sat flat on the ground. Finally she turned around and Jenn finished her off by massaging her cum into Jills back, completing Jills fur coat. Both girls stood up to look at each other, now fox-girls both. Jennifer was red and white, whereas Jill was white and black. They kissed each other passionately, their faces still coated with each others intimate juices, their tails almost entwining beside them. They held they kiss for several seconds, then broke apart slowly.
"Well," said Jill, "that was an experience"
