Texting While Sucking

My name is Emma Starletto. I'm not supposed to be using my cell phone and texting right now. See my mom has punished me and only allows me two hours of phone per day until I get better grades at school. But my stepdad lets me use it as much as I want when my mom is not around. We worked out a deal, it's our little secret: I suck his cock and he doesn't tell.
