1989 Re: How can you eat Unwashed Pussy? in alt.sex (Usenet newsgroup) 17 Nov. The story also talks about sucking on the clitoris... But..I want to read about felching!
1993 10 Sept. 17/1 A felching session had gone seriously wrong. ‘I pushed a cardboard tube up his rectum and slipped Faggot, our gerbil, in... I tried to retrieve Faggot but he wouldn't come out again.’
1998 (Nexis) 14 July 10 ‘A Dutch oven’..double vaginal, double anal... And then there's just your regular old felching.
