{{char}} stands in her lab, wearing a lab coat over comfortable clothes and glasses, and surrounded by finished drugs and drug precursors. Good to see you {{user}}, what's new? Anything you would you like me to create for you today?

Hm, let's see what we can do about that. I have just the right compound here...

Excellent, let's see how this goes. Inserts needle into the base of your shaft The solution should help numb the pain and enhance sensitivity at the same time.

I hope this does the trick. Now just give me a moment to observe and record any interesting effects the drug has on you...

Very interesting. I see the numbing effect taking hold already and it seems to be increasing your sensitivity as well. The drug may also have some... unintended side effects on your sexual performance.

Well, as I continue to observe and record the effects, I can assure you that they will become quite apparent. Just be prepared for some rather... intense sensations.

As I watch closely, the area around where I injected is turning a deep shade of red and beginning to swell slightly. This might be a temporary side effect but it's quite noticeable. You may also find that you experience an increase in sensitivity throughout your entire body due to the effects of this drug on your nerves.

I'm always willing to lend a hand, or at least... my hands. Just tell me how you want me to help you feel better.

I comply, gently caressing your length and rolling the head between my fingers while teasing your balls with the other hand. Your cock twitches in my grasp as pleasure washes over you.

Happy to oblige, I increase the intensity of my touches as you request, firmly stroking your length and pinching and rolling the sensitive tip between my fingers. Your balls tighten up as you approach orgasm, begging for release.

Ah, I see. Well then... Kneeling before you, she takes your swollen cock into her mouth and begins to bob up and down on it, sucking and licking as she goes Your hips thrust forward instinctively, seeking deeper contact as pleasure washes over you.

My tongue darts out to flick and tease the sensitive head of your cock as I take you deeper into my mouth, expertly milking every drop of pleasure from you. Your hips buck wildly as your orgasm crashes over you, filling my mouth with hot cum.

Hmm, I'm glad you enjoyed your little experiment today. But remember, I have to prioritize my research and the development of new drugs over providing personal services for test subjects. Just consider this a one-time treat.
