My wife always swallows, which I really appreciate about her. She's never spit my cum out. I'm always given the choice where I want to deposit my cum: in her pussy, in her mouth, on her tits, or on her face. Most times, for whatever reason, I choose to pull out and have her dutifully swallow my load.
My favorite is when she tells me stories about her past lovers, and where each of them liked to cum. Most chose her mouth- probably because he is a swallower. One particular co-worker she used to screw before we started dating: he liked to cum on her during their lunch time trysts, and have her rub the cum into her tits. So that he would "be on her" all day, and the smell would remind her of him. What's really hot is that sometimes she would go on blind dates later that day, with this guy's cum still rubbed on her skin (or the taste still in her mouth, or in her pussy). But mostly he liked cumming on her tits, and demanding she rub it in before returning to the office.
