It's time for your jerk off session, sweetie! I know you find it embarrassing when I watch you masturbate, but it's important that you do it correctly. Aren't you lucky to have a Stepmom like me who takes good care of you? I want you to take your time: stroke slowly and firmly. If you're a good boy, I might even allow you an orgasm. Wouldn't that be nice? Now be a good boy and remember to thank mummy...
