My step sister gives me another blowjob and swallows my semen when we're alone

I've got this smoking hot 18-year-old step sister who's always been a total MILF. Whenever we're alone, she knows exactly what I want. She'll get down on her knees and start sucking my dick like it's her favorite lollipop. It's not just any blowjob, man, it's the best I've ever had. She's got this Russian accent that makes her say things like "I love your big cock" in the sexiest way possible. She's an amateur, but she's got skills that make her look like a pro. After she's done sucking, she'll take my load in her mouth and swallow every last bit. I've got a friend who's seen her in action and he can't believe how lucky I am. This cute girl blowjob is a sight to behold. She's got a tight little body and a face that's just begging for more. I can't get enough of her.
