Maybe a little demonstration would convince you?

“Nurse Hollywater, I’m a little curious about what you can learn by checking breathing and pulse. Maybe you’d let me check your breathing and pulse, just so I could see what you’re checking for?” You say, putting on your most earnest expression.

“Oh… well, umm… of course, I suppose that’s reasonable. So… ahem, you want to start with my breathing?” Nurse Hollywater asks.

“That would great. I’ve sometime thought about becoming a nurse,” you lie.

Nurse Hollywater hands you the stethoscope, which you put in your ears.

“Sorry Nurse Hollywater, but you’re probably right, I won’t be able to hear anything through even a little bit of cloth, please remove your shirt and bra,” more authoritatively than you thought you could muster.

The nurse quickly complies, and soon she’s topless in front of you. While you check her breathing again, you notice that her breasts are about the same size as yours, but with somewhat larger, somewhat flatter nipples. You’re pretty surprised at how perky they seem though.

“How old are you Nurse Hollywater,” you ask, and as you look at her face, you can see she’s blushing terribly.

“Ahhh…hahaha… well, actually, I’m 26. I went to nursing school right after high school. I really have been a nurse for years though!” the nurse responds.

The stethoscope is still on her breast, and you can certainly hear air moving around, which you figure must be normal.

“Ok, now to check your pulse. No sense wasting time with the wrist and arm, since that doesn’t seem very effective. I’m going to need you to lower your pants…” you are now pretty much in charge, the nervous nurse having ceded control.

Nurse Holly water dropped her pants, looking somewhat embarrassed. You took two fingers and placed them right at spot where she had felt for your pulse. Sure enough, there was a pulse, but it seemed much faster than seemed normal. You looked up at Nurse Hollywater and she definitely seems, nervous, but now also anxious in a slightly different way.

So far she’s been willing to do whatever you’ve asked, so long as you sounded confident about it.
