The Nurses Lesson

It all started because of a kiss. Well, not just a kiss, Lisa and I were engaged in a full-on makeout session in the abandoned hallway of our high school. We were both pumping with adrenaline; this was about as rebellious as it got for a couple of scrawny straight-A students. Lisa didn't even notice the bell ring until I started to pull away. I could feel her disappointment.

"Aww, that's the best rhythm we've ever had." she said, frowning.

"Look, I was loving it too. But now we're officially late. And we've both heard the rumors about Nurse Yvonne," I replied.

"Look, I'm sure she'll be nothing but professional on 'Sexual Health Day,' just like everyone said she always is." my girlfriend replied sarcastically. We both laughed.

"No seriously," she continued "I was told that she's fine, as long as you don't go alone."

"Like, for example, by showing up late because you were making out?"

"Exactly. We just need to avoid doing that!" We both laughed again, but more nervously this time. As the tension increased, we started the long walk to our infamous school nurse's creepy office. By the time we got there, our casual walk had turned into to a full-on run.

"Why hello, you two!" Nurse Yvonne exclaimed as we finally made it to her office "So eager for your checkups! You're a bit late, but that just means we have all the time in the world."

Yvonne was a tall woman with large breasts, dark hair, an athletic build, and the uncanny ability to always be somewhere in the room you didn't expect her to be. Today, she was wearing a labcoat that was about 3 sizes too small, and a pair of high-heels that were not typical medical attire. As I stared at her, I was worried that Lisa would be offended, but a quick glance confirmed that she was as transfixed by this amazon as I was.

"So... Ken and Lisa, I assume? You're the only ones left. Got distracted having a bit of fun, huh?" Her question only partially broke my and my girlfriend's shared trance.

"Alright, go ahead and enter the exam room," she said, opening a door and gesturing us in.

As we walked in to the school's surprisingly-well-appointed exam room, Yvonne casually locked the door behind us and started giving instructions. "Alright. If you haven't heard, today we will be doing the most fun medical procedure of the year- a series of examinations to gauge your sexual health. To start with, I'm going to need the two of you to strip down so I can begin the examination."

I paused for a moment to make sure I was hearing her correctly, then stammered my first words to her of this entire interaction "Wait, you want us to... strip down... together?" I was far too intimidated to admit that Lisa and I had not seen each other naked before.

"Why not?" she replied, without missing a beat, "I find the act of working with couples together.. so invigorating." Her tone was a mixture of sultry and demanding that ensured my brain wouldn't even consider refusing to comply.

And so, my girlfriend and I stripped naked in front of each other for the first time, with our school nurse eagerly watching.

I suppose at this point, I should tell you what I look like. I recently turned 18, but I'm still easily the shortest and skinniest guy in my class. I try to keep my body at least presentable by keeping what little muscles I have toned and my brown hair should-length but well maintained. The only physical measurement I'm above average on is cock size.

My thoughts about my own body were quickly interrupted by my sight of Lisa's nude body for the first time. Lisa is even shorter than me (not a guarantee among women in my class), has beautiful straight brown hair and bright green eyes. But my real focus now was on her perfect (although smaller than average) breasts and flawless skin.

After an appropriate period of letting the two of us ogle each other, Nurse Yvonne gently got my attention, saying "Alright, now we can go ahead and get to the fun part of the exam. To start with, Ken, I'm going to need to examine your penis."

Without giving me a chance to react, Nurse Yvonne bent over and started rubbing my exposed member. I tried to voice an objection, but all I could manage was "Nurse... Yvonne..." before her skilled touch had made my dick rock hard.

"You can just call me 'Yvonne.' I think we're friends enough at this point. Or at least your beautiful erection thinks we are!" She then started writing something down on a clipboard. I could not imagine what it was. Still dumbstruck, I simply watched as she moved on to Lisa.

"Alright Lisa, get up onto the table. It's time for your vaginal examination." As Lisa silently complied, Yvonne turned to me "Feel free to watch. She is your girlfriend after all. You might even learn a thing or two!"

"Wait," I replied, "Shouldn't you be wearing gloves for this?"

"But it's so much more fun without them," Yvonne replied, as if that were a response that was impossible to object to. It arguably worked, because I had absolutely no retort- I just silently followed her instructions to look at what was happening.

I watched silently as Yvonne circled Lisa's private area until she got to the clitoris, which she gently rubbed. Just as I thought she was reaching a rhythm, Yvonne shocked both of us by abruptly sticking a finger into Lisa's pussy.

At this point, I expected some kind of objection, but what I heard from my girlfriend's mouth instead was a breathless "Yes. Oh yes!"

In response to this, Yvonne doubled down, fingering Lisa faster and faster until the breathless cries culminated in one "Oh God yes!"

As Lisa came down from her orgasm and Yvonne withdrew her finger, she smiled. "See, I'm already teaching you two new things for the bedroom."

Still delirious, Lisa murmured "Wow. No one ever put anything up there before"

"Wait. Really?" Yvonne said, looking legitimately shocked. Somehow, for the first time, we had managed to take her by surprise. "The two of you are still virgins?"

What followed was an awkward conversation in which the two of us feebly tried to explain that we were waiting for the right time. Of course, with my boner and Lisa's current state, the two of us had long since stopped believing it ourselves. Eventually, Yvonne decided to bring back her authoritative-yet-somehow-motherly voice and give us simple instructions. "Get back on the table Lisa. It's time for you to lose your virginity."

At first Lisa looked at me hesitantly, but then she glanced down at my boner, smiled, and got back up on the table. This time, I could see her beautiful pussy without Yvonne getting in the way. At least physically.

"Alright, Ken we've clearly had more than enough foreplay. It's time for you to thrust!"

Finally putting my dick in my girlfriend was possibly the best moment of my life. For a moment, everything finally felt right. Then I started to thrust, and Lisa's moans completed the experience. "Yes. Oh God, Ken! YES!"

As I began to speed up, out of the corner of my eye, I noticed that while we were distracted, Yvonne had stripped completely naked and started touching herself. Somehow sensing my attention, she moaned, "You two are -- oh- doing... great! Keep- keep going!"

Those words really set me and Lisa off and we started moving even faster. Lisa stopped trying to control her voice, "Yes, Ken! Yes, fuck me! Take me right in front of Yvonne! Make... Oh God yes... Make me cum! Ah! Oh! AHHH!"

As she started to spasm in blissful orgasm, I was close behind, finally getting to empty my balls into my girlfriend. I decided to make a vocalization of my own: "Yes! I love you Lisa!"

Right after I finished, my shout was quickly topped by the true queen of the loud orgasm, Yvonne herself. "YES! TAKE EACH OTHER! OOOOHH!" One last scream, then a scene of quiet.

As we began to return to our senses, I decided to join Lisa on the exam table so we could cuddle. She quickly pulled me into a hug and gave me another kiss. To our surprise, Yvonne walked over and decided to pull a blanket over our naked bodies. "You two did great," she said with a smile "So I'm going to make sure we have an exam like this every week."
