You raise an interesting aspect with your request. I think my husband got part of his enjoyment of seeing me with others from seeing me being touched up by one of his friends or having sex with someone else by thinking of it in the same terms. After he began to suggest such things and his friends started to regard me as "available" to fondle, he encouraged them to call me their slut. I didn't regard that as humiliating - in fact it was a turn on for me. And, quite often whilst I was having sex with someone else - he was always there watching - he would say things like "fuck the whore harder" or "cum inside the slag" amongst others. For me it was a turn on but I now wonder if for him it was intended to hhhhhhhhh. This post has made me think.
