Considering the topic it should be a sperm donation clinic.
I notice a handsome man walk into the sunlit little clinic, I walk over to him in my slutty nurse outfit and with a bright smile I greet him "Hi, and welcome to our clinic, please sit down and relax. The condoms in the bowl are free so please take as many as you need, we don't want anything to get spilled now do we?" winking at him.
I wait for him to sit down before I lean down to hand him a tablet, his eyes falling down to my cleavage "Here you can see the nurses working today, we'd like you to choose one out of them that will help you through the process in a most... enjoyable way".
I glance down and notice the obvious hard-on in his pants and my smile widens "Of course, the more you can provide the more compensation you will receive from doing this tiring and bothersome work. Now, take your time to choose and when your ready I'll call the nurse for you".
