^When I was in college, my girlfriend had a lot of money saved. She'd pay for everything of mine. I went along with it for a while, until I realized she was doing it out of guilt - because she was cheating on me. When I found out, I didn't do anything for two months and let her keep on paying for everything. I was giving her what she wanted, and she maintained my standard of living.
I was in a similar situation with another girlfriend in college. They didn't want to be labeled as a lesbian by Johnny Fratboy, so essentially I licked pussy in exchange for hush money.
