Penis Training with Her

An hour earlier.

* * *

“Let’s train our pelvic floor muscles!”

As soon as we entered the VIP private room, Mari uttered those words.

“Pelvic floor muscles?”

Of course, I had no idea what she was talking about.

Mari, with her smooth tone, explained it to me.

“Pelvic floor muscles—also known as PC muscles. They are the muscles that mainly support the bladder and intestines! Training these muscles has various benefits for male se*ual function!”

“O-Oh…”

“And if I explain it with a diagram, the location of the muscles seems to be like this…”

Mari showed me a cross-sectional diagram she had sketched herself on her phone.

It was an incredibly well-drawn illustration, given that she was an active illustrator, but all I could say was, “Oh, yeah…” What else could I say in this situation? I couldn’t keep up with her at all.

“So, these PC muscles, although they support the intestines and bladder, they also have the role of retaining blood in the p*nis. So, in theory, if you train these PC muscles well, your pe*nis, Sei-kun, can become a muscle pen*s that can maintain an erection for a long time!”

“T-That so…?”

“So, I’ve researched muscle training to strengthen these PC muscles of yours, and I want you to do it!”

“Y-yeah…”

“Hmm? What’s wrong, Sei-kun? You seem a bit down… Did I say something wrong?”

“N-no, I don’t think so.”

Mari’s words being right or wrong was a minor issue at this point.

It wasn’t Mari who was wrong.

It was the situation.

What a sad situation to be in, coming to a sports gym with my girlfriend and having to do erection training.

And Mari was so serious about it, too. I didn’t understand much, but the logic behind the training probably wasn’t that wrong.

But the situation ruined everything.

Why?

How?

Why am I being forced to listen to my girlfriend’s “erection enhancement method” theory in this place!

I didn’t confess to Mari to do this!

“Alright, Sei-kun! Let’s work hard together for this penis training!”

Mari smiled brightly as she made a tight fist.

She’s so cute.

“Y-Yeah, let’s do it!”

Mari was so cute that I thought I might as well go along with it.

However, my thoughts were once again completely shattered by Mari’s next statement.

“So, Sei-kun, take off your pants and underwear!”

“Huh?”

“Take off your pants and underwear!”

As she said that to me, Mari took out various tools from her bag.

Thin rubber gloves, lotion, an egg-shaped mysterious tool…

“Wait, wait… let me confirm something. I mean, Mari, can I ask you some questions one by one?”

“Huh? What is it, Sei-kun?”

“You see… I’m about to do the training for these PC muscles, right?”

“Yeah!”

What a good answer. So cute. But…

“…why do I have to take off my pants and underwear to do the training?”

“Well, it’s said that the most effective exercise for training the PC muscles is to tighten and loosen the anus.”

“T-That so… but even then, I don’t have to take off my clothes, do I?”

“Well, but to make sure you’re doing it right, it’s better if I touch you directly, right?”

Wait, there’s another point to argue about.

“Um, Mari. Just out of concern, what do you mean by ‘touching directly’?”

“Huh? Of course, by putting my finger in your anus while you’re doing the exercise, I can tell if you’re doing it right, right?”

I mean, that might be true.

I mean, what she’s saying might not be wrong.

But just hearing it made my crotch go “Suuu.”

Hey. Mari-san. Hey, hey, hey?

“Oh, don’t worry about being seen by others! This is a private room, and we became VIP members for this purpose!”

…That’s not the point.

“Also, I’ve prepared gloves and lotion. So even if it’s your first time, you don’t have to worry about getting hemorrhoids, okay?”

…That might be true.

“Oh, by the way, this is mine. Ta-da! V*ginal Training Balls! I’ll work hard on my vaginal training too, so I can make Sei-kun feel even better!”

…I see.

“Let’s chintore!” (T/N: P*nis Training)

So, I was looking out the window at the familiar streets of my town and tightening and loosening my anus with a blank expression.

I could feel the presence of Mari’s finger, the certain foreign object there, as I tightened and loosened my anus.

Ah, looking at it this way, my town is quite cluttered. There are things you don’t notice until you take a step back and look at it. With such thoughts of escapism, I tightened and loosened it again.

“Tighten~”

When Mari said that, I tightened.

“Loosen~”

When Mari said that, I loosened.

“Good job, good job♡ You’re so handsome, Sei-kun♡“

I thought it was a different kind of handsome, but I tightened and loosened. Tighten and loosen. Tighten and loosen.

“Sometimes, this kind of date is nice too, isn’t it, Sei-kun♡“

I think she being serious, which is a bit scary.

[TL: I’m speechless…..but I wonder if that’s true. Do you guys know?]
