Chelsea, Harper, and Shelby were life long friends working at a fertility clinic together, they loved their job. One day while administering a new fertility gas to a patient, the tank sprung a leak, and they each received 10 times the normal dose. In the haze of gas and confusion Harper knocked over the giant vat of mixed sperm samples. It spilled throughout the room inseminating all three of them. They emerged from the procedure room looking nine months pregnant.
