My stepdaughter asked me for help with her homework, but when I went into her room, I saw her on her bed in her school uniform, trying to do her homework. I couldn't help but grope her bottom until I lifted her skirt and saw her delicious panties! My dick reacted immediately, getting hard, so I started rubbing it between my little princess's luscious buttocks. She, without losing concentration, continued focused on her homework. While I kept rubbing myself against her ass, one of my sudden movements caused my cock to end up penetrating tight pussy. It was at that moment that I lost control and started fucking her. It was several minutes of pleasure where I pulled hard on her panties and rammed repeatedly her ass until I finally felt like I was going to cum, i pulled my cock out of her pussy, and my cum fell onto her buttocks, staining her panties. It'll be really hard to explain to my wife why our princess's panties are wet.
