Abby is definitely the most masochistic girl in my team. She loves being screwed, literally. This time her big inner labias were nailed and screwed to a wooden stick. I think no one else would have done it to Abby so erotically than Jessica. Both Abby and Jessica enjoyed every moment of this session. As a preparation Jessica drilled two holes for the screws with a screw driver machine and then she nailed Abby's labias to the wooden stick to fix them. After that she used a manual screwdriver to turn in the screws and in the end Abby had three nails and one screw in each of her labia minora. After removing them she had huge holes but they completely healed and disappeared in a few days.
