Dr. Neville removed her suit jacket and dropped it to the floor.
Due to a new bone structure and increased muscle, Betty lifted her tail up in the air until it served like the back of a chair to Dr. Neville. She could feel the scales push up against her back as it inched her closer to Betty.
"Unbutton."
Dr. Neville was not hypnotized, but she might as well have been. She slowly unbuttoned her shirt and started to take it off.
"No, leave it on. Keep unbuttoning."
Dr. Neville looked down. She forgot what bra she wore today. It was a secret she kept from her patients. Sometimes she liked to wear one of her favorite black bras. It had a nice lift, but she loved that it could unfasten from the front. With one hand, she quickly unhooked the strap in her cleavage. Her breasts impressively dropped.
With an open shirt and an open bra, Betty had never noticed how hot her doctor was. She pushed her even further until they were an inch away from each other's mouths.
Even with the short proximity, Betty couldn't hear Dr. Neville's whisper. "Speak up."
"Make me a mermaid."
Betty didn't need to be asked twice. She grabbed Dr. Neville's head and kissed her like her life depended on it. Their tongues frequently grazed each other, Dr. Neville laughed in pleasure as she bit on Betty's top lip. All while knowing what was building inside her. She was infected. She could grow a tail. She could double the size of her tits. And it made her so fucking wet.
As much as Dr. Neville wanted to cum, she also desperately wanted to taste a mermaid. She slid down Betty's tail, loving how it felt as it rubbed against her. She was right, there was still an opening where Betty's crouch used to be. With one hand, she spread open the scaly lips and with the other she put her hand down her pants.
As Dr. Neville explored the inner workings of a mermaid, Betty felt the heat rise up inside her. It was like her clit was even stronger; she wanted to know how it would feel if water rushed past it. She lightly grazed her boobs, but then she needed more. It was coming. Her tail kept flapping on the ground, causing items on Dr. Neville's desk to move. She pulled on her nipples as she let out beautiful siren's call as she shuddered from the waves of her orgasm.
Dr. Neville grunted as she kept getting more turned on and rubbing herself faster than she has ever done on her own. It wasn't enough so she leaned forward so she could insert digits inside her. The angle wasn't right. She got off of Betty and sat on the floor in front of her desk. She quickly kicked off her heels, and pulled off her pants and panties. She never felt the carpet on her ass before.
Betty was in awe as she saw Dr. Neville exposing herself and getting two fingers inside her. Betty slid off of her chair and knocked it out of her way. She dragged herself backwards up against the door, her tail stretching as far as Dr. Neville's feet. It was one thing to fantasize about her doctor and it's another to see it.
Dr. Neville watched as her patient mimicked her behavior. While holding one of her giant tits, Dr. Neville watched as Betty slid her hand down her tail and found her opening. Betty was slowly discovering how she felt and Dr. Neville changed her speed to match Betty.
They kept eye contact except for when they simply had to look at their exposed bodies. To avoid being too loud, Dr. Seville bit her lip too hard. Betty was usually a screamer even when it was just herself, but as a mermaid her cries came out as beautiful singing. The sound started another wave inside Dr. Seville, which caused her to slide further onto the ground until she was on her back with each leg on the side of Betty's tail. Both of their bodies shook and the tail kept brushing up against Dr. Seville.
They had no idea how much time has gone by. They both breathed deeply with smiles they couldn't hide. Betty breathed in deeply and sighed as her tail had a light glow under her scales. She moaned as her pussy moved towards its original location, causing a division in her tail that continued down her body as the feeling of legs began to return. It looked like she had long yellow legs with diver's fins at the bottom. The tailfin started to recede as her legs regained their thin pale shape.
Betty sighed as she held her large breasts one last time before they shrank to their original size. She popped up and put back on her top and her maxi skirt. Betty beamed as she said, "Thanks for the cure, doc. I'll close the door on my way out."
Dr. Neville was still in shock as Betty left her office, too exhausted to even try and hide for the split second the door was open. This is going to be an interesting discussion with her husband tonight.
