I need to collect a sperm extraction from you, but so far all previous attempts have failed. Luckily I'm a very hands on nurse and I decide to use an unorthodox approach to collecting your sample. I tell you to fuck me over and over again (roleplaying with my fuck machine as your cock) and I want you to cum inside my pussy. I'm very confident that this new method will have you cumming in no time. Now fuck your nurse and make me moan ;)
