Ooookaaay. I posted the dirty lady file before Christmas, I heard the oral couple last week and posted them Saturday. My filing system is such that files, once posted, go onto an external drive because I don't want them sitting on my laptop. The dirty lady file had been transfered off my laptop long before I heard the aural couple, so I know there's no overlap.
I give you two other pieces of circumstantial evidence: (i) Why is the aural lady not using dirty talk? and (ii) listen to the man's grunt in each case when he comes. They are definitely different.
I'm starting to enjoy this discussion, it's given me a chance to revisit my files.
By the way, I've made two new recordings since last week's postings. However, I'm not going to post them here until people actually listen to these files and recognise that they're different. Otherwise, what's the point of me writing the descriptions telling you how I made the captures?
