Mid 20's woman stranded on island with youger male

[nicka26]

I would like to develop a story with a woman about a woman between 22 and 28 who is stranded on a tropical island with an 18 year old guy. There would be turf battles at first and lots of tension. Ultimately this would give way to sexual desires and passion, with a fetish or two thrown in for erotic pleasure.

It could be great, maybe they come from very different backgrounds which would add to the fire.
