Yes. The "Quickshot Cure" - a pill making it extremely hard for a man to cum, improving sexual endurance

"I'll...do it..." After a bit of hesitation, Adam agrees to Dr. Miller's offer. Though he'd never admit it out loud, having the attractive doctor laying her hands on his member on a regular basis is a large factor in his decision.

Dr. Miller smiles faintly, looking pleased and turning to the desk to select a test product. "Daily, at the same time, is alright with you?" When Adam nods nervously, Dr. Miller selects a bottle and hands it over.

"This is 'Quickshot Cure', it's designed to assist men who have issues with ejaculating too soon during sexual intercourse. It should become far more difficult to cum after taking it, but there hasn't been much testing so far."

Adam accepts the pill bottle, and Dr. Miller smiles faintly again. "Don't take anything yet. Tomorrow, after the salve is completely worn off, we'll do a control test without any medication. After that, we can try some trials with the medication."

"Right..." Feeling a little disappointed about not getting a handjob from the doctor, Adam turns to leave. As he does, Dr. Miller calls out to him one last time.

"Ah, one more thing, you should refrain from masturbating for the sake of constancy in the trials."

Embarrassed at having his masturbatory habits discussed, Adam nods and leaves the office.
