Blackmailed by my Stepson, Into Fucking Him!

Description: My stepson approaches me after finding my explicit videos online. he uses that to his advantage and says he is going to tell his father about my endeavor if i do not do exactly what he asks. it turns out the little pervert wants to not only see me naked, but for me to touch him, blow him, fuck him, and take his load in my mouth. i need my marriage to work, and my life to stay in tact, so i cave and give him everything he wants. am i the best stepmommy in the world; or the absolute worst?
