Movie scene happens in restaurant table. Woman and possibly two or three other persons are at the same table. Woman has witch’s teat in her thigh and familiar or some creature crawls under the table and starts sucking her witch’s mark or teat. Im not sure but if I remember correctly, she in ecstasy and stabs one of the other people to hand with a fork.
I think i saw this movie in 80’s.
Thats all I remember.
