There are a few porn flicks where an actress pretending to be a doll is unboxed by a bloke and shagged senseless while trying to maintain her inanimate role... I find them oddly erotic, but also hilarious as the women never manage to stay "in character".
I'd much rather pay an SP to pretend to be a sex doll, than go to some room in the middle of nowhere and mess around with an actual one.
That Adultseek advert is borderline tempting. A much better deal than the link shared by the OP.
