Reverse Cow Girl
I had no idea what Lenna Lovings had in mind when she stated she had a wonderful surprise in store for me. It transpired that her younger stepsister was occupied with her games and couldn't bother us because her parents were away. I was about to enjoy my beautiful girlfriend when my stepsister, Sera Ryder, popped in through a keyhole. That was no longer acceptable, so my dear partner made the decision to take action. It was only natural for her to grab her younger stepsister and drag her into the room so she could play along in our activities.
