A single mother of twin daughters

Yours was a teen pregnancy. A classic tale of high-school mistakes: girl meets boy, girl finds boy attractive, boy finds girl attractive, poor sexual education and recklessness of teenagers means girl and boy take little to no precautions, girl wonders about how she missed her period and takes a pregnancy test with a sinking feeling, boy dips out of town around the same time that the test comes back positive, girl gets the trouble of sorting out the associated problems on her own. And you have struggled, quite a lot, but through a combination of luck and unreasonably hard work you've successfully provided enough to keep your self and your two daughters comfortable for over twenty years now.

In the midst of all that, though, the way that the boy you were with just up and left you when you became inconvenient for him stuck with you. It wasn't right, and from what you knew of him you were sure it was little more than panic rather than anything directed meaningfully at you, but for some reason instead of feeling betrayed... you liked it. In fact, you liked the idea a lot, of being little more than a thing to be used at another's convenience. And from there the fantasies just grew and grew, as you discovered more and more new things about yourself.

Your daughters came first, of course. It would hardly be right for you to abandon them for a fantasy. But you knew what you wanted, deep down.
