Ariel goes for the special waterbed

               "I hate to be such a burden to you. Since you are trying to help me find true love but that rubber waterbed with the seawater and air pump sounds so good I could just fuck you again." Ariel says as she reach up for you as you pull away typing the order as you do.

                "Now wait it will be here in a few days and then you can show me all the joy you feel once your in your new bed but right now I need to get some rest on a real bed or I will not be any use to you." You tell Ariel. 

                  After a few days  and the two of you get used to fucking in the tub the bed finally comes and they install it as Ariel hides in the bathroom. You tell them it's your girlfriend getting ready to try the bed out in her mermaid costume in case they take a look at Ariel in the bathroom.

                   Then you lift Ariel to the bed when they are done and gone and slip her into the rubber water part. So she could feel the ocean for the first time in a long time in cased in rubber. 

                    She lets out a moan and cum inside your waterbed  as she feels so turned on my the feel of the sea all around her mermaid body. As she reaches up and touches the rubber she feels your body on top of her causing her to cum even more in the waterbed in bliss.
