You decide to confess to your sister that you find her attractive. The response is pretty bad. She's disgusted and decides she should probably tell on you. However, you planned for this response. You looked into magic and using it to change the world and people around you. Your sister will soon be exactly what you want her to be as you snap her into different clothing, give her longer hair to make her look hotter, snap off those glasses... put her in sexy, sexy lingerie... and make her into a big slut who WANTS to suck her own brothers cock! Ohhh, but you never know, you cum down her throat and in her belly may cause a reversal!
