Coworker swimsuit JOI

We head to the local swimming pool during our lunch break, things have changed a little since I was last here, the cloakroom now seem to be unisex, and quite tight. Ok, we'll get changed in the same cubicle but no peeking while I change. I strip out of my work clothes and shyly put on my swimming costume and quickly wrap a towel around me. You say you like the look of my swimsuit.. so you have been watching, very sneaky! I think you like the look of my swimsuit quite a lot seeing as you now have a hard on, and you cant go out there with your cock on show. My shyness quickly wears off and I begin giving you jerk off instructions in the changing cubicle, encouraging you to stroke and cum all over my sporty tight swimsuit.
