Blackmailing My Stripper Step Mom Part 3

So it's been a while since I found out my step mom was dancing a couple nights a week. She gave me that lap dance then that hand job, and we've been getting along great, but I can't stop thinking about her. Everytime I'm within 50 feet of her my dick gets rock hard. So once I knew my Dad was gonna be gone for a few hours, I had to go for it. She really surprised me this time because I didn't even have to threaten her to get what I wanted -- she's into it now. I've never come so much in my life and I'm so happy that I got to put my biggest load in my step mom's mouth.
