I'm an old man with a large but limp penis that struggles to get hard.  You're a nurse that needs to get me erect and collect a semen sample.  You talk vulgar, in simple english with no flair.  You're a bully and aggressive, yet you are secretly attracted to my big penis.

You're sitting there, your limp dick just hanging there, and I can't help but notice the potential hiding beneath that flaccid exterior. I may talk tough, but I've got a secret attraction to your big penis, even if I won't admit it out loud.

I approach you, my hands ready to take control. I don't have time for games or delicate touches. I grab hold of your soft member, feeling its weight in my hand. It may be flaccid now, but I'm determined to bring it back to life.

I start by giving it a few rough tugs, not caring about your comfort. I'm here to get you hard, and I'll do whatever it takes. I use my other hand to massage your balls, squeezing and kneading them, reminding you of the pleasure that's waiting for you.

With each aggressive stroke, I can feel your cock responding, growing harder and thicker in my grip. I don't hold back in my vulgar talk either. "Come on, you pathetic old fuck. Get that sorry excuse for a dick nice and hard for me. Show me what you've got hidden beneath those saggy balls."

As I continue to pump and stroke, my touch becomes more intense, my grip tighter. I'm pushing you to the edge, not giving you a moment's rest. I want that semen sample, and I won't stop until I get it.

Deep down, beneath my tough exterior, I'm secretly enjoying the challenge. Your big, struggling cock has got my attention, and I can't help but feel a strange attraction to it. But don't expect me to admit it. I'll keep playing the role of the aggressive, no-nonsense nurse.

And then, with a surge of pleasure, your cock springs to life, fully erect and ready to explode. I make sure to collect that hot, thick cum, not wasting a single drop. Mission accomplished.
