"No" it echoed in his mind. Kyle had to fight the teenage pumped up hormones and resist the urge to continue masturbating. His self pleasure was going to be his doom, once more. He dramatically spread his arms and placed them on the wall, facing the bed where the frog-girls were having their best time. Although he wasn't caressing himself, his penis stood erect as the sight was exciting.
While giving Becca some head Sam realized what was happening to their frogman pet. She smiled, retrieved her tongue from inside Becca's pussy (causing a deep moan) and confronted him.
"What's wrong, Kyle? What are you doing...Aren't you enjoying yourself?"
"I won't go back to frog, that's for sure" Kyle answered, his will was strong but fought with a laughter.
"Well your resistance technique isn't working".
Even Becca participated in the laughter which was interrupted by random inflated throats and smoother croaks. Kye coouldn't believe that he was still changing afterall. His crotch was green with small spots of a dark green. His pubes had fallen and even the pink head of his little Kye was changing to a paler version. The skin was spreading to the the rest of his body, in a bat of an eye it reached his chest whose muscles developed and a swimmer's torso embued him. His legs became more powerful and forced him to bent slightly. His breathing regained a rythm. He put his eyes again on the bed action...Becca's leg were spread as wide as she could while Sam feasted on her. They switched glances with Kyle and licked their lips.
He didn't hold it.
The visual stimuli was overbearing...and he orgasmed. Kyle grunted and the euphoria got hold of his body. A warm sensation covered all his body, his spine twitched and his throat inflated like a balloon letting a deep "RIBBIT" escaped. He was thrown to the floor and softed his fall with his new frog hands that slapped the floor. He could feel his new tongue acomodating in his mouth a new vision field made him possible to almost see his back. The warm feeling stopped and gave in a cold wave that responded to the humidity in the air, like if he had came out of the shower.
"There you go, a big and new frogman for us!" Sam exclaimed.
"I'm not even wearing a suit..." Kyle whispered.
"It seems there's no way back now" she answered. " Come, we need a strong male!"
