Karen took the kiss full on her mouth. She used her hand and held Zack's chin in place between her fingers. She could feel his skin fluctuating and flowing between her fingers. She felt him morphing and suddenly found that she had to lean slightly down to continue the kiss. Finally, after a good thirty seconds, she broke the contact.
Zack's lovely feminine form greeted her eyes. He had bright red hair and a smooth complexion that was dotted with freckles on her cheeks as well as along her shoulders and exposed neck, though it looked as though they ended just short of her breasts (which were still covered by a fashionable, if slightly cleavage revealing top) which were an absolutely delicious C-Cup, "Whoa..." the girl said, looking slightly confused, "Hey...that was...nice Karen...but we've been friends for, like, 3 months now. I mean, if my name weren't Serena, I'd be really confused right now. What was that kiss about?"
"Did you like it?" Karen asked, still admiring Zack/Sarena's form. She was definatly pleasing on the eyes.
"Yeah..." she blushed, "But Karen...."
"Wow, that was totally HOT!"
