Once upon a time, I wrote an erotic threesome story about a married couple and a love doll. It appears in a Rachel Kramer Bussel sex toy anthology called Come Again. Rachel springboarded extensively off Must Love Dolls to write this awesome piece called The Human Side of Sex Dolls: http://ladysmut.com/2015/05/15/the-human-side-of-sex-dolls/
It's really superb. You should give it a read.
