I'm the best step-sister ever, so I treat you to breakfast in bed. Soon after waking you up, I notice your morning wood showing from under the blanket. I'm shocked and entirely impressed by the size of your dick. That can't be your dick, come on! It's massive. I doubt whether it is truly the size it appears under the blanket and beg you to show me. You're hesitant but eventually pull it out. I'm so turned on by your monster dick I can't resist it: I start by stroking it and soon progress to a blowjob. I have you cum in my mouth and I swallow it all. I want to do this every morning, it can be our naughty morning routine!
