Jake found himself aroused at the sight of Kelly's naked green frog body. He knelt by Kelly's side, checking her over - out of genuine concern as well as attraction. She seemed unharmed, just...changed.
"Are you okay?" Jake repeated. "How did this happen?"
Kelly caught her breath and tried not to let her new tongue get in the way of speaking. "I'm okay. I bought some special leggings off the internet" she said, gesturing toward to the discarded clothing. "More special than I ever imagined. What do you think?"
Jake kissed her passionately. "I think it's been awhile since I wanted to have sex with you as much as I do right now" he admitted.
Kelly smiled. "Good, because I want to be fucked so badly right now. Just not on this floor."
Jake scooped up Kelly and carried her to their bedroom where he set her down on the bed before stripping off his clothes. Kelly assumed a frog-like position on all fours. When Jake approached, she wrapped a webbed hand around his penis and stroked it. Then she switched to her mouth while fondling Jake's balls with her hand. Jake had to brace himself on Kelly's shoulders as she ran her tongue up and down his shaft. He struggled not to climax right there, so amazing was the oral. No human tongue could do this. Kelly showed no signs of stopping. Jake felt slightly dizzy with pleasure. He suddenly blew his load. Kelly kept sucking Jake off until he was done and collapsed on the bed.
Kelly licked her lips, enjoying the taste of Jake and happy she had pleasured him so well, but she craved her own orgasm. She lay back on the bed and began fingering herself, which proved difficult with her webbed hands. Then Jake, having had a moment to catch his breath, crawled between Kelly's legs and began kissing his way up the inside of her muscular green thighs. He didn't realize he had a frog kink until today. Soon he had his face buried in Kelly's crotch, his tongue probing into her slimy depths. Kelly fondled her own breasts, which she found more enjoyable with her webbed hands. Jake had never been so eager to go down on her before, but after the oral she'd given he certainly owed her!

As Jake and Kelly snugged in the afterglow, Jake asked "How was it?"
Silence. "It was good, but..." Kelly finally said.
"You wished it was my dick instead of my tongue?" replied Jake.
"That or a tongue like mine" admitted Kelly. "You experienced what a tongue like this can do."
