Carmen walks in and catches her home builder on the phone with his girlfriend talking about what a dumb ass she is and how she doesn't even know he is working illegally without a contractors license.
Carmen is pissed about the delays finishing her house and she decides to teach this guy a lesson he will not forget. The poor guy has no idea what is under her dress so when she offers him the choice of being 'Hammered' by the contractors board OR getting 'Nailed' he chooses the latter.
He had no idea that Carmen was packing her own tools and knows how to use them. She puts him through a rigorous apprentice program of cock sucking and getting his ass drilled. She finishes with a huge facial so he better understands how good it is to get the job done right!
