The Expert Swimmer. {Shanks x Reader}

So, I haven't been writing for a while due to a lot of issues at home and for that I apologize. I was asked ages ago to do a happy Shanks x Reader and an actual story of it rather than a oneshot and naturally, I wanted to be up for the task so I really had to take a break and try sorting out my head a bit before working.
Now, I'm not feeling 100% but I've tried and I hope you enjoy it.
Also rating it as mature just for caution, there might not be any sensitive parts but I dunno, known me it will be bad language.
Anyways, hope you like and of course, I own nothing.
