Caught my little step-brother in his room being suspicious. So took hisipad to find that he’s been watching giantess porn. But his searches are all based around a step-mom or step-sister. What a little perv. I continue humiliating him for his embarrassing fetish. Found a folder with drawings of us as giants. This is getting out of hand. I can feel him getting hard under me as i continue teasing him. As i hump and make fun of him. Threaten to tell everyone. He cums in his pants. What a loser. Maybe i won’t tell but only if we can play like this again.
