"Daddy's Girls" has Ryan McLane, a veteran of Bree Mills' "Tricky Spa" series of Oiler vignettes concerning massseurs who trick femme clients into having sex with them, as a fake-religious father who irritates his step-daughter Alison Rey by bringing home a church-sanctioned foster child in the form of sexy and glamorous Karlee Grey. Opening scene features Rey's mom played by a plus-size performer who doesn't speak and whose face is never shown on screen -probably a crew member tossed into the show.
It's all about incest, but a very lengthy sex scene that becomes a three-way has Rey, given to talking to herself aloud in order to deliver the story's exposition, seducing a reluctant dad McLane and then seguing from a catfight with Karlee when the new kid in the house catches them at it to both 2 on 1 dick action plus lesbian sex while everyone continues to scream at each other (when their mouths aren't full, that is).
The trio sort of stay in character, except that artistic license by Mills and her co-director Craven Moorehead) has them behaving as sex-crazed beings above all else, indicated by the unlikely lesbian action between such adamant rival siblings.
