"Becca, how about you use your new tongue on Kyle?" suggested Sam. "I'd love to watch"
"Dammit, Sam" said Becca "I wanted to get pleasured by a frog, not turned into one."
"Suit yourself" said Sam. "Hop on up here, Kyle. I think you deserve to be rewarded."
Kyle gladly obliged, step-hopping onto the bed. Sam pulled off her shirt and bra (her pants and underwear having been taken off before Kyle orally pleasured her earlier) then gently pushed Kyle off his squatting frog position into a seated position. The shift in Kyle's legs from the transformation made a seated position feel a little awkward, but that though entered Kyle's mind only for a moment before Sam went down on his erect penis. She seemed eager to pleasure him and pretty adept at it. As much as he wanted Becca's new frog tongue sliding down his shaft, Sam's human tongue was a hell of an alternative. He was getting close to a climax when he felt Sam's lips slide off his penis.
"Time to make me a frogwoman too" said Sam.
She climbed onto Kyle, cowgirl-style, and directed his slimy webbed hands to fondle her breasts. Sam was soon riding Kyle with the same glee she had shown pleasuring him with earlier and was moaning with pleasure that Kyle didn't think it had much to do with his technique. He held back as long as he could before erupting into Sam who collapsed onto the bed panting heavily.
Kyle ran his webbed hands down Sam's body and she moaned further. He glanced over to Becca who, whatever her initial shock at turning into a frog, was now eagerly watching Sam and Kyle.
