You're here testing out our newest product and getting paid to be a guinea pig. I've just finished taking your vitals, and tell you to put your clothes back on when you reveal to me that you think the product gave you some kind of side effect. You have a massive erection that just won't go away! I tell you that you can't walk out of here like that, so you'll just have to take care of it quickly. I look away so you can stroke your cock and get off, but you tell me that you like me to watch, so I do. I comment on how swollen and hard your cock looks. Is it always like that? I dirty talk you some more but then notice your orgasm isnt progressing as quickly as I'd want it to. I take off my lab coat and reveal my bra and titties. Then you tell me you have a panty fetish, so I show you my white lacy panties I have on. I tease you with my panties and body as I order you to stroke for me. Finally you cum for me and your boner goes away. That was quite an interesting part of a clinical trial!
