My father, a veterinarian, has remarried, and I live with my mother-in-law and sister-in-law. One day, an attaché case is sent from his father, who is on an overseas assignment for drug research. It's a domestic PTM that happens with a trigger (a play that repeats inserting it again after sucking the cock inserted in the mako and making it clean). The super horny sex of two people who suddenly change is a must-see!
