It's time to have a talk with your favorite sister. Since you've gone away to college, you've been behaving like a jerk. You're so full of yourself; the way you're treating girls is disgusting. As your sister, it's my job to teach you, my naughty brother, a lesson in respecting women. What better way to do that than to transform you into a girl yourself? Take off those ridiculous boy clothes. You won't be needing them anymore. Instead, you'll be wearing a frilly pair of floral panties and a cute, feminine dress. Don't even think about walking away - see this laptop I'm holding? It's yours. Full of dirty porn. What would mom and dad say? Better to obey your sister than find out. My brother looks so pretty as a girl! But it doesn't seem like your attitude is changing as I'd hoped. Hmm...I think it's time to take your punishment to the next level. You're not just going to be a girl, you're going to be a baby girl - fitting given your infantile behavior. Time to take off those panties and replace them with a baby diaper. Open up wide for a nice pacifier as my soft diapee encases your baby butt. See? It's so much better to be a baby girl for big sis than a dumb, disrespectful man. I'm going to keep you just like this, my sweet baby sister, forever. No more big boy! You're just a little girl now.
