After overhearing a secret phone conversation between your step-mom and step-dad, it becomes apparent that your step-mom is ovulating RIGHT NOW and needs him to come home to impregnate her.. it SHOULD turn your stomach imagining your step-mom naked and having sex but it doesn't.. your step-mom is the only woman you've ever truly wanted.. desired.. and now she's in desperate need of someone to give her what she wants.. and if your step-dad isn't up to the job then.. well.. it'll HAVE to be you..
