Big dick for younger stepsis

What do you do when your stepsister lets you walk up on her naked and says she wants your dick right in your face? Riley's been provoking me for days and finally I gave up and let her give me a blowjob. Damn, this bitch can suck! She made me so horny I just had to fuck her like she was some hottie from the club, not my younger stepsis. Her pussy felt so good and she swallowed my cum too, wow! Hope mom and dad won't find out and we can keep doing it.
