There's some nice details like "Richie had his cock semi hard staying up with a bent upper part. It was glistening in the sun from all the cum on it." but if this is indeed from a female's perspective, maybe give some more details of the narrator's feminine body.
Otherwise, the setup of three individuals above the sea in a nice luxury boat obviously lends itself to very sexy times. Make sure to give more details of where in the world are we. Is this off the coast of New England? Caribbean? New Zealand?
