Tabou, histoires de belle-famille

(This is a point of view via the husband's eyes) Mom, husband, stepson are in the bedroom. Stepson lays on bed out of sight. Stepmom & husband are super kinky and have very taboo sexual desires. Husband can't get mom pregnant so stepson needs to step-up. Stepson is opposed but stepmom/dad leave him no choice. He's being ungrateful after everything stepmom/dad have done for him. He is perfect for the task. Young with potent sperm to get stepmom pregnant. To make it easier, stepson's arms are tied to the bed. Husband can't wait to see his wife fuck their boy's cock. Stepmom talks very dirty, gives a striptease, a hand job and blow job to the stepson. She looks at husband (camera) a lot as she fucks stepson. She rides him with intense desire. Stepmom grinds down hard on his cock. Daddy loves watching. Stepson is made to cum inside mom as she begs for his cum. Good stepsons are supposed to make their parents happy.
