Sarah/Zac had finally made it to where Sarah was heading. It was a huge cave. Sarah entered it and inside was a small pond with water that was glowing. Zac had no idea what it was, as he wondered Sarah began to remove her clothes until she was completely naked then she began to walk towards the pool, Zac didn't know what to do, but she had taken over his body so all he could do was watch from her point of view. She slowly walked into the pool, as she did the water began to glow brighter, she laid down in the pool with all but her head under water. "Now Zac watch what we came here for, this pool is going to turn us into a sexy 25 year old woman". Zac couldn't believe what he was hearing. "Ah i can feel it working" she Said, Zac could to as the changes began. She/he felt her hands tingle as they grew to a full grown woman's hands followed by his arms growing longer, next she/he grew taller and her/his legs became more feminine, her/his butt trembled as it grew more fuller becoming more toned and firm, next her/ his small b cup breast began to jiggle and tingle as they began to grow again to big firm cc cup jugs, then her/his shoulders grew wider as her/his neck grew longer, finally her/his face changed from an innocent 14 year old girls face into a sexy Playmates face, her hair then grew longer all they way down to her new butt. Sarah then stepped out of the pool and admired her new body. She was nothing short of a goddess. Zac was looking down to, he was sure glad she possessed him.
