The final, penultimate step of Oliver's plan is to rock a boner in plain sight. When Eva sees it, Oliver acts embarrassed even though he knows his plan is about to come to fruition. Eva assures him that it's natural. From there, it's only natural, of course, for mom to make a move. As Oliver planned all along, Eva has been daydreaming about Oliver's dick since she saw it earlier. Once Eva has popped Oliver's cock out and started stroking it, there's no going back. Soon enough Eva's lips are wrapped around Oliver's fuck stick sucking him off in a hot and horny BJ.
Getting to her feet and letting her dress fall to the floor, Eva turns around and spreads her ass cheeks so Oliver can get an eyeful of her chocolate starfish and pussy. Her hands shift to her big boobs as Oliver leans in for a pussy feast. Then she sits down on her stepson's dick as Oliver guides his mommy with his hands on her hips while she rides him. Her reverse cowgirl ride transitions to Eva on her hands and knees with Oliver pounding her lush snatch. Then he gets mom on her back so he can finish her off with a hand wrapped around her neck. Pulling out, Oliver jizzes on Eva's stomach as the final act of his stepmom seduction.
