I've been asking you to fulfil my sexual desires for a while, but you always turn me down. You don't want to watch your wife fuck another guy, you don't want to be a cuck. But I'm insistent this time. And I know all about your dark taboo desires. You think I haven't noticed. The way you look at her, the times you've called out her name when we've been fucking. You want to fuck your Step-Sister, and I know the perfect way to combine both of our fantasies. You're going to watch whilst I fuck my own Step-Brother, being my pussy denied cuck, whilst jerking off, thinking of your Step-Sister.
