Hey guys, this is gonna sound kinda weird...

anyway, I drink a lot of milk. I carry a milk carton with me just about wherever I go, doesn't matter if it gets warm, I just fucking love the taste, right? I'll generally have a few litres a day. And a result of this is... um, a milk fetish - yes I know how that sounds.

I told my girlfriend this via fb a few minutes ago, and she thinks I'm joking. Is there... some sort of way I can break it to her that I'm actually dead serious about this? I would actually really get off on just pouring milk all over her naked body, and hearing her moan as the dairy trickles down her breasts onto her stomach... oh god, should probably stop typing that. :/ Anyway, we joke around a LOT in our relationship (we make a lot of awkward jokes, or ridiculous jokes, etc) and we're very good at having those joking conversations in a dead serious manner, but we both know the other is really joking

How do I get her to know that I actually am NOT joking about my milk fetish, and I want her covered in full cream milk? I don't think she believes me
