DeepThroat Practice With My Step-Brother!

My boyfriend finally told me what he wants as his Christmas gift.. He wants a blowjob for his gift but I don't know how to give a blowjob! I want to make sure it's a really good BJ but I need help from someone I trust first. Ya know, we're not fully related right? I could practice on you and you can tell me if I'm doing good or not! Don't worry, our parents don't need to know about this.. Mmmm look at that hard cock staring back at me, begging to be sucked. I start off slow, building up the tease and suspension. I slide my step brother's cock deeper down my throat until I'm completely fucking his cock with my throat! Okay, maybe this isn't my first time giving a blowjob, but I've been wanting you to cum in my mouth for so long!! Thanks step-bro!
