My Stepsister Never Sucked Before

This morning i woke up a bit earlier than usual and caught my stepsister naked in couch . She was touching herself. So i use the situation. And tell her if she don’t suck my cock right now i will tell to parents what she is doing. So she was shocked and don’t want to parents know that she was masturbating at family couch . Before she start to suck my limpy cock i didn’t realize that this is her first blowjob. Enjoy!
