I've only done real Cream Pies and full Leather a handful of times because it's SO HARD to clean.
But it does feel absolutely amazing. :). Met a woman at a local laundromat and after handing her my business card she wanted to put a cream pie in my leather pants. She was ecstatic that I let her. After she did it she was eyeballing me and point blank asked me if I was getting off on it. I just gave her a smile and she cocked a eyebrow, gave me a sly smirk and then smacked the other cream pie in my face and slowly/sensuously smeared it around.
