I'm never so horny as when I come into a stash of cash.

It's God's way of stimulating the economy.

Psychological studies have shown that most of us experience a sensation akin to an orgasm whenever we receive a substantial amount of cash.  So, if a provider gets paid for fucking at least once a day and is truly orgasmic with her clients, her  endorphin levels must stay off the chart!

Especially when you're getting in your civvy life as well.  
Ecstatic!  
When I get restless in my sleep it's because I see visions of white envelops in my dreams.
