You, my brother in law, find me poised naked on the bed while your brother is out of the house. You're surprised, but not alarmed enough to walk away right away. I confess that your brother (my husband) hasn't fucked me in MONTHS. I need someone with a big cock to properly satisfy me, and I heard you have a big thick cock that could do just the trick. I beg you to show me, and the sight of your monstrous ween leaves me dripping wet. We can't fuck, but mutual masturbation isn't cheating... right? I rub my wet pussy for you, and use a vibrator to cum hard with my mouth open while begging for your cum. Please, won't my brother in law cum in my mouth?
