It's been a while since Step-mommy and Step-daddy got intimate and Step-mommy feels so neglected. You and her have a conversation and she is telling you that she has been neglected in so many ways and she has been crying her eyes out lately. She even thinks Step-daddy has a mistress. Because you want to help her, take action and try to satisfy her although is wrong and Step-mommy is really reluctant to that because it's so fucked up on so many levels. You push and grab her despite her reluctance. She keeps telling you to stop because she's still very fertile and this whole story might end up into impregnation. You still proceed and fuck Step-mommy until you cum inside her.
