Despite the worried expression on Rachel's face, the sight of her as a half frog gave Marty an immediate erection. He remembered their earlier lovemaking after Marty first transformed and his later self-pleasure at a pond while still froggy.
"I'm sorry" he said to Rachel. "You're scared. We need to get help. We can find the witch again. She can give you the same liquid she gave me to change you back to normal."
Rather than be offended, Rachel was relieved. She also remembered how turned out she got by seeing Marty turned froggy; she had been worried the feeling wouldn't be mutual. But knowing Marty desired her as a frog as much a she desired him as a frog...
She licked her lips. "Help later" she commanded. "Horny now."
Rachel hopped onto the bed and motioned Marty to join her. He sat down on the bed, unsure of what she had in mind. Rachel pushed him gently onto his back, spread his legs wide, and lowered her mouth toward his crotch.
