Rachel is walked into the lab by Dr. Cupcakes and Dr. Straps with her hands bound behind her back. The two Doctors get to work on their next experiment. A clear polymer strap, that Dr. Cupcakes developed, will be used to bind Rachel. The harness is buckled into place first. Dr. Straps seems to enjoy groping and smacking Rachel's ass in between tightening straps. A matching head harness ballgag is applied next. Dr. Straps then starts tightening straps around Rachel's legs. Dr. Cupcakes then cinches them with zipties, making sure they are ultra tight. This is where Part 1 ends.
