Jake woke up later while Kelly still slumbered. He went to the bathroom and relieved himself. He thought about Kelly's wish for him to have a frog tongue. Surely the leggings would transform him as they had transformed her? Jake went to Kelly's office and picked up the green leggings from the floor. They seemed to small, but he decided to try to get them on anyway. He carefully slid his legs and and the material, though snug, seemed to stretch. With a gentle tug they reached his waist. Jake could feel how tight the material clung to his butt and groin, but he found the sensation enjoyable. He returned to bed.
Kelly woke up later, briefly, but just snuggled up against Jake's body, enjoying the feel of his arms around his cool, smooth skin against hers.
When Jake woke up again he was spooning with Kelly. With his groin snuggly against her butt he felt aroused, but his arousal felt strange somehow. He supposed it was just the leggings. He slid his hands up Kelly's chest to caress her breasts with his webbed hands.
Webbed! The leggings had worked! He could feel the enlarged tongue in his mouth.
"Kelly," Jake whispered in her ear, "I've got a surprise for you..." He tickled her ear with his tongue.
Kelly stirred in Jake's arms. She felt his hands massaging her breasts. Webbed? How?
Jake released Kelly so she laid on her back. Then he moved down the bed, positioning himself on all fours like a frog, and leaned down to Kelly's groin. Half-awake she had her first glimpse of Jake's green body. Something about it seemed off. Then Jake's frog tongue slid into her. It was everything she'd hoped for and she was quickly lost in a haze of carnal delight. As Jake pleasured Kelly, he felt his own arousal growing, but instead of the normal sensations he felt...wet. He stopped what he was doing and sat up on his knees, looking down over his changed body for the first time. Two firm, green mounds unexpectedly obscured his view. He fumbled for the top of the leggings with his webbed hands and, with difficult pushed them downward.
The abrupt stop surprised Kelly. She opened her eyes and looked at Jake. Her eyes went wider at the sight of the frog girl kneeling on the end of the bed.
