This is a completely implausible hypothetical. What girl is going to let me have my way with her if I suck a dick first? That's ludicrous. And the answer is no. I would do filthy, unspeakable things to Autumn Reeser, but I wouldn't suck a dick for that chance.
You have to suck a guys cock before spending a night with your own dreamwoman. Would you? and (this gets kinky, I know), which famous man would you go down on?
This just popped up in my head, while thinking what I would do to spend the night with Nina Mercedez gotta think it through myself and will get back later with my answer.
