Ns1 I have to say, I don't know about your attitude towards women...
I fired my gf. That however is a boss/worker relationship. She works in exchange for money, but it's my money, so when I don't want to give it to her anymore, I don't have to.
I reserve the right to withhold the penar as well. She works (cooks, cleans, dishes, rubs feet), in exchange for sex. Sometimes she misses a few spots. No ticky, no washy.
You're talking about HER money here, though. How can you tell her what to do with her money?
Tips and advice are welcome because this idea sounds like it has potential.
