Reverse Cow Girl
Molly Little, your new stepsister, has been observing you whenever she had the chance since she moved in. She will even enter whatever area you're in only to talk and flash her adorable ass and tiny, toned physique. You eventually reach a point where you have had enough and decide to either put up or shut up. When you "accidentally" bump against her in the bathtub, she begs to suck your erect cock rather than becoming alarmed. You two go to her bedroom to fuck her as soon as she's finished gobbling your knob. After months of building, it's really satisfying to watch her bounce on that cock. It's a good thing the house is always yours because it's going to turn into a stepsis fuck pad.
