After catching mom cheating with the neighbor, you decide this will be the optimum time to use it against her to get what you want. After joining her in bed for a "nap", you wake her by lifting her nightie and touching your cock to her ass and then tell her if she doesn't do what you want, then you are going to tell your father about her fucking the neighbor. Reluctantly, at first, she agrees to go along with it, but then realizes your cock is much bigger than your father's and ultimately is consumed with passion.
