There are certain unspoken rules in findom, and one of them, is that a leaky cock equals a leaky wallet. It's so rare for a sub to tribute after he's already cum, but when that cock is dripping, when you feel the pressure in your balls and you're reaching those edges for me, your wallet is oh so penetrable too. I like to think of your wallet as a tight little pussy. I have to get it to warm up, I have to make it soft, and open, so that I can slide my greedy fingers right in. I just keep taking as it's gaping, providing endless waves of pleasure yet never quite letting you reach that climax you ache for. Because for as long as that cock is leaking precum, your wallet is leaking cash for me too. Allow me to demonstrate... ;)
