Short story (4258 words).
Nina has a massage guy. She has been seeing Kevin for a year, and knows he has a girlfriend, but she still has little fantasies about one day hitting on him. She never quite has, because she worries he will turn her down, but the temptation always seems to be there.
She begins thinking about it more often. Thinking too much. Asking people for advice, and fighting with her boyfriend about Kevin, and it seems like everything is going a little far, and getting complicated, as if she’s fighting for something she hasn’t done, and doesn’t want, but yet she keeps on fighting for it.
And that almost makes her think she ought to try.
This one is free and short.
