When we were there, I removed my clothes with a lot less apprehension than I normally should have. There was something magical in not being afraid to show myself to her since she felt the same toward me.
When I was nude, my body wasn't of much interest to her except for my "mutation". She often glanced at it when we bathed even though she tried to be discreet about it. It seemed she was curious about that obvious difference between us.
I sat on the bed and started my explanations.
"Men are quite easy to please. They usually feel it a bit less on the rest of the body but their mutation is sensitive. Wait. Let's stop calling it mutation. Its official name is a penis."
"It even has a name?"
"Right. Just like your groin area is called a vagina, there's a name for that part for men. And because it's the most obvious difference between men and women, it's gotten a lot of derivative names over the years. Like dick, cock, schlong, and whatnot. In the same manner, women's vaginas receive a lot of alternative names, like pussy, cunt, twat, and so on."
"Huh… That's a lot of information to remember."
"It's not a big deal. It's just so you don't be surprised if I use a different term."
"But, why have so many names for the same thing?"
"You know how the massage feels good, right? Well, some of these names are a bit vulgar and that excites people if they use them when they're massaged."
"I don't get it."
"It's fine, it's not very important. Anyway, the main point is that when massaging men, the focus should be on their penis."
"Okay. Does that mean you don't want a full-body massage like you did for me?"
"It's not that it won't feel good but it's also not absolutely necessary to reach orgasm."
"I understand. So, how should I handle your… "penis"?"
"The only limit is your imagination but the most common ways are to use your hands, your chest, or your mouth."
"Alright."
She nodded with determination. She then looked at my boner and pondered for a moment.
"I have one last question. Why is your penis small sometimes and why does it grow big like now?"
"Very good question. It's similar to how your vagina gets wet. It means it's ready to feel pleasure."
"That was the reason?"
"Yes. There's also another reason but I'll tell you when we get to it."
"Okay. Then, I'll start now."
I opened my legs a little and she came to sit next to me. A normal woman would probably have kneeled in front of me to facilitate the work but it was interesting how that wasn't her first reflex.
With hesitation, she extended her hand to my dick and stopped right before touching it.
"Tell me if I hurt you or do something wrong, okay?"
"I will. Go on."
I was already quite excited to finally receive Suuru's attention and her halt felt like she was teasing me. Fortunately, this was the last one and she finally delicately took hold of my raging hard-on. Her soft fingers felt both a bit cold and nice on my cock and I couldn't help shivering a little at the contact.
She was now holding my shaft around the middle like she would hold a metal bar but didn't do anything more.
"What should I do next?"
"You need to move your hand up and down to stimulate it."
I then pointed to my glans.
"You see the top part there? It's the most sensitive spot, a bit like your clitoris."
"I got it."
With slow movements, she ran her hands up and down my tool and I let a sigh of pleasure slowly escape my lips. While I took care of myself quite often, it couldn't compare to innocent Suuru doing it for me.
"There's a bit of liquid at the top of your penis."
I redirected my attention to it and could see she was right.
"That's pre-cum. It's also a bit like when your vagina gets wet."
"I see."
"It's mostly for lubrication purposes. Using it or saliva feels better than just rubbing skin against skin."
"Saliva? Just like how you licked me?"
"Exactly. You're a quick learner."
She smiled a little, just as she always did when I praised her. Then, she pondered for a second before taking off her hand from my sex. She then spit a bit of saliva on it and smeared my length with it. I was amazed at how she precisely understood how to do things.
After that, she resumed her up-and-down movements, now much slicker, the sensation more fluid and pleasurable for me.
"Nice… You're doing great, Suuru."
"Does it feel good?"
"It feels amazing."
She grinned again and went on with her handjob. However, she was still a complete novice at the act. Which meant, she only did that for a long time and nothing more.
Eventually, my lust grew too high and I needed more stimulation.
"Can you go a bit faster, Suuru?"
"Yes."
She accelerated her back and forth and the pleasure increased again. I decided to guide her in the right direction until I reached my orgasm.
"Good, just like that. Now, increase your speed progressively until I reach orgasm."
She nodded and did exactly that. I also gave her a few more advice from time to time.
"Try to stimulate the top part every so often. That's where it feels the best."
"If you can, use your other hand to softly massage under my penis. Yes, these sack-like parts. They're called "balls"."
"It's okay to change your pace when you feel like it. It makes things more interesting."
And so on. Suuru was a fast learner. She was motivated and executed my instructions to the best of her ability. Seeing her so dedicated to the task and with the renewed sensation of getting an increasingly skillful handjob, I soon reached my limit.
