Lily is a sweet girl that went to a clinic to be artificially inseminated. However once the Doctor has her naked with her legs spread wide in the stirrups he explains that it is a NATRUAL Insemination clinic and proceeds to use a medical device to induce orgasms so that her vagina is ready for the donors.

Between donors the Doctor continues to administer orgasms to aid in the insemination. He also squeezes her throat to help her maintain proper breathing techniques
