Girl in Local Pool who sends the inside of my Speedos Insane

[Papadoop]

Basically theres this girl at my local pool.
Shes tanned, nice body and wears a Black Swimming Costume that shows off her body, her face is Ok but she has this long black hair that near goes down to her buttocks.
Everytime she approaches the Sauna I end up with a Stiffy and cant remember an occasion where I havent blew my load in my briefs when shes been around.
Spoke to her and she seems nice enough but dont think shes into speedos but she just turns me on so bad dont think she knows how much she arouses me
