Fucking my best friends step-dad

You come home to your step-daughter having a party with a dozen or so old friends from college so you go straight upstairs to your room to escape the noise, luckily their in the basement mostly so you can barley hear anything from there. You know everyone in the house, they grew up playing with your step-daughter at one point or another, she was a popular teen. A few you didn't know would grow up to be so beautiful, and some you did. Once you get into your room you see a young bald woman wearing a tiny red dress with her legs wide open, bearing her freshly shaven pussy. Your instantly turned on but confused as to why this hot young woman is in your bed. Then, the second she apologizes you realize who it is. It's your step-daughter's best friend, Briana! Little Bri was practically your second step-daughter when the teens were in college, but she's all grown up now. You both sit and talk for a few minutes, catching up. Briana didn't want to go back down to the party quite yet.
