Learning to control your transformation

The Government extended the lockdown so it looks like you would be stuck at home for another 2 months at least. Your sister came home from her University flat, not being able to stay there as spring became summer. She had to share the bathroom with you and the others to continue to shield your brother. You let her know that you knew she was half mermaid but kept your relationship with mum a secret.

With the house full of people it was harder to sneak around. You would always run salt baths but you couldn't transform unless your mum dunked your head. On the few occasions mum could make it to the bath, she would slip in after you transforming with no effort. Then she would hold your head underwater until the pain came and then you would embrace it and take on your mer form.

Next, you would have sex; as quietly and gently as possible to avoid excess splashing that might alert the family. Most of them spend their time watching T.V downstairs or playing games using various consols shouting into their headphone mics which conveniently masked the sound of splashing and moaning from the bathroom. By the end of the first month of extra lockdown, you could transform by simply having your head forced underwater.

Also in this time period, you creped into your parent's bedroom at night. One these occasions you fucked your mother as humans while your farter watched or helped. The first time was really something.
