My wife takes care of all our finances, so any money I make goes directly into our joint account. At times I can make a little "extra money" by doing extra jobs etc and I always bring it to her on my knees and offer it to her. My wife usually says that I am a good little sissy and snatches it from my hand laughing!
Sometimes she will ask how I am for money and if I have anything at all in my wallet. (I rarely have much, but sometimes enough for "emergency petrol" incase I breakdown anywhere etc).
I will always answer honestly and sometimes she will offer me a little to have in my wallet, other times she will just laugh at me and say "tough" and not give me anything.
At one point we discussed that I should ALWAYS have to pay for any kind of sexual contact with her ( Im usually never allowed intercourse and NEVER allowed blowjobs but can receive hand jobs at times, or be allowed to come over her feet as she watches me ).So for any of these things I would have to pay her for it, otherwise it simply wouldnt happen!!! It would be difficult for me to achieve anyway as she gives m very little money so saving for a sexual adventure would take close to a year with the prices she told me at the time !
Anyway....the idea never really got put into practice for whatever reamister.
What can happen at times however is that if I have managed to do and "extra job" somewhere that she does not know about I can come home with around $400 and I will say to her "look what I have" I want to pay you for sex tonight and she will agree and come to me and I will had over the money to her. I usually leave it up to her what kind of "sexual contact" Im allowed, but its often to be masturbated by her as she talks to me about kinky humiliating things ;) .
