Mary looked at her changes and felt her tummy. It was softer than before and had some slits at her sides. She probed one of that slits and winced in pain when a finger slipped inside it.
“Ouch! I have some kind of bruise here!” She said.
Jeff looked at that slits and recognized them. “They are gills! Are you able to breath underwater now?”
“Am I? Please! Take me to the pool!” Mary asked euphorically. “I want to test this now!”
Jeff stood up and Mary quickly used her tentacles to climb his body until she was eye level with him. She kissed him full in the mouth and he walked to their pool.
They had quite a large house and their pool was on the backyard. They had no neighbors facing their backyard since it faced a mountain with a forest.
She took Mary to the pool and as soon as he was on it border Mary jumped into the water. Jeff saw as Mary struggled to coordinate her tentacles to swim and soon jumped into the water. As soon as he pulled her by her arm, she used her tentacles to hold onto him and put her head over the water.
“Let me guess,” Jeff said “you don’t know how to breath underwater and how to swim using your tentacles, am I right?”
“No,” Mary said with a grin, “I wanted you into the water with me!”
Mary submerged and climbed down Jeff’s body. She used her tentacles to undress him and soon was sucking his cock. Jeff was excited and felt her ministrations becoming more and more like a pussy, enveloping his cock entirely and squeezing it lightly while sucking. He leaned on the border and caressed her head, only to feel her skull soft. He couldn’t see what was happening to his wife since the water was too wavy.
Soon he saw as two tentacles climbed his body up to his neck and embraced him. The tips of these tentacles caressed his face. He felt something caressing his balls and couldn’t hold it anymore as he came hard into Mary’s mouth. He felt as she released her grip on his body and swam away from him.
Jeff saw as Mary’s shadow underwater came back to him and soon two tentacles emerged and embraced him again. He felt as her tentacles held his legs and were climbing his body. Soon she surfaced, but she looked totally different from when she went down on him.
