This Girls a stank tramp?

She gave me oral in a park, thing is she knelt in dog muck when she did it. Didn’t even seem to bother her. I’m kind of tired of her skank act, at the same time she pleasures me. I know I’ll miss it when she’s gone. I think I’m only attracted to the idea of her being sleazy? I hate her personality. Also, she gives me lots of money cause her dead parents left her inheritance. I’m one of those guys that do. I need to upgrade now (and get some self respect). How do I make a clean break without her getting all fanatical over it?
