I am engrossed in a report for work when you enter the room sheepishly and ask for some advice. You look like you've seen a ghost so I immediately put my work to one side to listen to your troubles. You eventually confess that you've been perving on your Step-sister. That you saw her taking selfies and she even caught you with a hard cock staring at her. Eventually you break down and tell me you stroked your cock for her. Of course I understand. It's natural to be curious and I'm proud that you were brave enough to share your secret with me. It must have taken a lot of courage to be so honest and I have no intention of shaming you for it. You're my Step-son and I care about you very much. But I can't have a testosterone fuelled hard on wandering around the house wanking at my Step-daughter when I'm trying to work, so it's time for a little life lesson. I commend your bravery for opening up to me, and in return, I share a secret of my own. I've been aware of your little escapades, and now, I want to join the excitement. I want to see this famous cock of yours and teach you how to control it. I can tell you're already hard, don't try to deny it. The evidence is written all over your face and bulging from your trousers. I know you are aching to take it out for me and show me. Show me just how hard and girthy your naughty Step-mom makes you. Show me how big your dick is. I instruct you to reveal your hard cock, the very one that's been causing all this trouble. I watch with eager eyes as you obey, your manhood springing free, thick and pulsing with need. It's clear that your Step-mom's attention has you more aroused than ever before. Now stroke it for me, stroke it like you stroked it for your Step-sister. I expect full obedience as I enjoy the sight of your dick being pumped in your fist. I guide your hand, teaching you how to stroke your shaft with the perfect rhythm and pressure. My top slides down, exposing my tits – those very tits that have fuelled your fantasies. Now, they're yours to admire as you pleasure yourself under my watchful gaze. With each stroke, you edge closer, under my command. I can see the desire burning in your eyes, the anticipation building to a crescendo. And when the moment is right, I give you the permission you crave, to shoot your hot cum, just for me. Your dick belongs to me now and you willingly accept ownership. This is more than a mere handjob tutorial, it's a forbidden journey into the depths of your carnal desires, guided by the one woman who knows you better than anyone else. I know you're ready to please your step-mom.
