Hey step-daddy, I have a confession to make! I kinda looked into your phone and found all those sites you've been using to meet other women, and I don't think step-mommy would be happy about that, so I had this amazing idea that will help you not to cheat! I found you a pink cock cage so we can lock up your dick to keep you faithful, and if you don't agree I'm gonna have to tell step-mom everything! So you better put on this cock cage, and I promise to let your cock out whenever I feel like you're allowed to fuck step-mom. I just don't want you going out of the house without that cock being controlled! And if you think I'm bluffing, I've got all the proof to show to step-mom that you've been a cheating bastard! So are you prepared to take slight measures to stop you from cheating, controlled by no other than me! And if you agree, I promise step-mommy will never know!
