When a girl knows that she can get whatever she requires as long as she flashes some knockers and strokes some dong, she's going to make sure to do it on every guy that she can, even if that man happens to be her step father. Jessie Andrews has thoroughly seduced her stepdad John Strong by pulling off her bra and showing off hot perky knockers. She promises that she'll take good care of him and goes for a rimjob and a blowjob. That's a full service penis sucker if I've ever seen one, and that's even before she goes and fucks the hell out of him.
