I wrote this for another board earlier today, but I thought I'd post it here too — some of you might find it interesting. It's a very real, honest account of my first experience with scat (with another person). It's written for a non-scat-practicing audience, but I might come back to this post later and edit it to include the sorts of details that you all might be interested in knowing. This took place about three years ago.
There's not much to tell, really. I'd been jerking off to scat porn for a long time and thought I'd finally try it for myself, but it took me a lot of courage to finally arrange the meeting. We messaged a bit on the website at which I had found her, and I told her exactly what I wanted.
We met in a hotel room that I had booked in Berlin. I was so fucking nervous the half hour before she was due to come, then finally I heard a light knocking at the door. It felt surreal to see her then, to know that we'd be doing such sexual and disgusting things later. She was dressed quite cutely, it was winter so she had a nice coat, a scarf, and a hat.
I started off by offering her a drink, but she only had a bit of water. She got undressed while I laid down on the bed, then once she was undressed she got on the bed too, and sat on my face, pushing her warm, slightly wet pussy down onto my mouth. I ate her pussy out like that for a few minutes before she shifted a bit and put her asshole over my mouth, which I licked too. I noticed that it tasted much stronger and more bitter than her pussy (which tasted somehow slightly salty to me).
She'd only been sitting on my face for about ten minutes before I suggested we go to the bathroom for part two of the "session". She warned me that most men are unable to swallow or even chew shit during a first session, and she also wanted to know how far she was allowed to go in forcing me to do it. I just shrugged and said we'd work it out as we went along.
I laid down in the empty bathtub as she squatted over my face, with her feet up on the sides of the bath. She started off by pissing on me, but she was too far backwards and so I moved my head away to avoid her piss going in my eyes (getting piss or shit in your eyes is a nice way to get a serious eye-infection). Her piss was relatively clear, with a bitter taste.
Soon after that she started to shit. She pressed her asshole down onto my mouth, I could feel the hole opening wider as I tongue-fucked her. Then the shit came. She was shitting a lot, too much for me to even have in my mouth, so I moved my head away again after a bit and let her shit on my chest and face. The smell was much stronger and less appealing than I'd imagined it would be, and I'd even lost my erection by then, which was annoying. After she was done shitting I licked her dirty asshole for a bit, tasting the very bitter, almost medicinal traces of shit left behind on her ass.
She got up, then, and seemed disappointed that I hadn't eaten all her shit. I got up too, and looked at myself in the bathroom mirror. My lips were brown with her shit, and there were smears of shit over my cheeks, my chest, and even my back (since I'd leaned back in the bath against her pile of shit).
She said then that the session was done, and after wiping herself clean, she quickly got dressed, counted the money I'd given her, and left. It was only after she left that I finally came, jerking off furiously to her shit that was left behind in the bathtub (while I did this I was also chatting with some other scat fetishist friends in a online chatroom)
So all in all my first scat experience wasn't as great as I thought it would be, but it still didn't put me off wanting to try it again, but that's a story for another time 
But for me it doesn't matter and i would like to read more here. Please post a continuation.
