My classmate

At college, I was the class nerd, and I was also the richest student attending the college. But it was a secret from everyone except Danica; she came from the same small town as me. She didn't expose my wealth; she decided to use me to make her way through college easier. Local jobs for college students were in short supply. Me being well off and didn't need to work due to a large allowance. She could have exposed me, but then she would have a lot of competition. Couldn't threaten exposure; left her with only one choice. Use me; she offered me sex in return for financial support. Acting as my girlfriend, she got financial support; I got sex. She also couldn't date anyone else either; neither could I, but I wasn't on anybody's possible list of boyfriends. During our time at college were together, studied together, and regularly slept together. We graduated in almost equal places in our class. But the years together had made us closer; we had actually become boyfriend and girlfriend. We married within a year of our graduation.
