for Advance Chapter
Shiina Mayu had a problem.
Recently, I have become aware of my interest in sex, and my sexual curiosity, which until now was merely a matter of knowledge, has become uncontrollable.
In other words--
"What's going on with a man's penis?"
--It was a worry just like that of an adolescent middle school student.
They are illustrated in health textbooks. I understand the physiological phenomena of erection and ejaculation.
However, having never seen one in real life, Mahiru couldn't concretely imagine the reality that a man had something that she didn't have.
"Searching online... somehow doesn't seem right."
It's not that I just want to see anyone.
I'm sure if I looked into it I'd find something, but I think it would just make me feel disgusted.
However, every time Amane goes into the bathroom to masturbate, I can't help but imagine it in my head.
"I wonder how men masturbate. I'm curious."
Recently, Midday had been thinking about such things all the time.
--Aname's point of view--
"I'd be happy to split the cost of food in half and cook it in your room."
After that, we made some detailed arrangements and it became a daily routine for Mahiru to cook in Amane's room.
With everything from preparation to tidying up, it was becoming a common sight for Mahiru to hang out in Amane's room until late into the night.
(Speaking of strange things, it's "that".)
Mahiru was sitting politely on the long sofa and was reading a book.
However, the book he was reading was one of Aname's treasured possessions... an erotic book.
Although at first he was very interested, he pretended not to be interested while Aname was around, but recently he had begun to read freely, albeit timidly.
"...Huh...?! ...Wow."
However, it's her facial expression that's the problem; she blushes every time she turns a page, and at times she swallows her saliva and becomes so engrossed in the book that it's just too adorable.
(I told you I wouldn't attack.)
He doesn't have any intention of attacking her to begin with, but Mahiru is so cute when she makes all kinds of faces while reading the porn magazine that he can't help but reach out to her.
Lately, I've been finding myself becoming entranced by the way Mahiru stares with such delight while eating her food, so I need to exercise a little self-control.
Although he doesn't think he wants to date Mahiru or that he could date her, he is reminded once again that she is an incredibly beautiful girl.
On top of that, people have been letting their guard down a lot lately, and even though it's starting to get a little chilly, they're often wearing light clothing or no tights, which makes it hard to know where to look.
Aname is a healthy high school boy, and sometimes gets an erection when he sees a girl's skin in a sensitive area.
Each time, he would deliberately declare that he was going to masturbate and engage in self-stimulation in order to make Mahiru more alert.
He had been prepared for the worst, even if he was disliked, but Mahiru was wearing light clothing in opposition to the season, and was relaxing with an inviting vulnerability.
(Without any consideration for other people's feelings at all...)
It doesn't feel bad knowing that he trusts me that much, but I wish he could understand Amane's situation, having to exercise self-control every time.
"Um, I'm going to the toilet to jerk it off, Shiina, it'll be about time for you to--"
--I was about to continue, "It would be better if you went back to your room," but Mahiru gave me an unexpected answer.
"...Isn't it fine to do it here?"
"...teeth?"
What on earth is this angel saying?
"This is Fujimiya-san's house, so you don't have to go to the trouble of using the bathroom; you can just do it here."
"No, I don't think that's going to work."
"I, I use the restroom here too, so it would be a problem if the smell lingered. Besides, I don't really care what you do."
He talks very fast and rattles off. Well, masturbating in the bathroom is a bit cramped, so if he doesn't mind, I'll let him.
"Okay, then I'll do that, but please don't complain later, okay?"
When I pulled down his pants, his semi-erect penis was already making its presence known even through his underwear.
"...Gulp."
"...Shiina?"
"Y-y-no, it's nothing!"
Mahiru turns her gaze back to the book she's been reading, but can't hide the way she keeps glancing at my dick.
It was a little embarrassing, as expected, but he thought it must feel really good to masturbate while being watched by the famous angel Mahiru.
I had always thought that being seen masturbating by a girl my age was an impossible situation for me, but when I actually found myself in that situation, I found myself rather excited.
As he forcefully pulled down his pants, Aname's thing, already fully erect, shot up.
"...! Hyaaaaaah!"
"Hey, who said I don't care?"
Mahiru's face turned red and she covered it with her hands as she let out a small shriek. She was still staring intently through the gaps in her fingers.
"B-but it was bigger than I imagined and had a strange shape..."
"I haven't compared it to other guys so I don't know if it's big, but I think it's probably about this big."
(I mean, even Shiina can imagine a man's penis. Well, she's been really interested in porn magazines lately.)
"Um, well... if it's that big, won't it interfere with your daily life?"
"It's not like this normally. Besides, boys release their frustrations by masturbating every day so they don't accidentally get big."
Mahiru seemed oddly convinced, "I see." All the while, her gaze never left my face.
"Well, that's why I'm going to masturbate. First, I need to prepare some toys and a masturbator."
With a bang, he placed the latest pornographic magazine, a masturbator, and some lotion in front of him.
By the way, the subject of this post is "Angel Heroine Fallen Angel Anthology vol.3." There's nothing particularly deep about it, I think.
"Um... what is that?"
"This is lotion. When using a masturbator, you need to make it slippery with lotion or it can hurt, and it also doubles the pleasure."
"Is that so?"
As I said this, I poured lotion onto Aname's thing. This cool sensation became addictive.
Then, after applying it thoroughly, just stick it into the masturbator.
"Hmmm, fuuuuh."
"...Hmm, it really does feel good."
"Yeah, I carefully selected the onahole to suit me. It's just the right tightness."
While talking, he strokes the onahole up and down. The room is filled with lewd squishing sounds.
"Wow, there's a sound."
"Hmph, hmph... the lotion makes you look even more erotic, right?"
"Y-yes, that's right."
Until recently, Mahiru would have turned her face away and said, "I don't know," but today she seemed to be truly honest about her sexual desires.
"Hmm, hmm... hmm."
"..."
"Haa, haa."
"...Hmm."
For a while, the only sounds were the squelching and Aname's heavy breathing, but then there was some movement coming from Mahiru's direction.
"Hmm, hmmm... Shiina?"
"Ah, hmmm,... what is it?"
When I turned my gaze towards Mahiru, I saw that her hand was in her crotch, although it was hidden by the bag on her lap.
"What, did you do it?"
"There's nothing special. Fujimiya-san, why don't you just masturbate without worrying about it?"
"...ah"
(I said masturbation...)
Even though she said there was nothing, it was clear that Mahiru was also masturbating, and the fact that Mahiru clearly said the word "masturbation" made Aname even more excited.
"Fuh, uhh, I'm almost coming."
"Yes, ah, ah, ah, I don't particularly mind, so please go ahead and cum."
He hasn't even looked at the new porn magazine he bought for a long time now, and is masturbating facing Mahiru.
Their excitement grows as they masturbate together.
"Ugh, I'm cumming!!"
"Ahh, ahh, mmmmm!"
They both climax at almost the same time. The inside of the onahole is filled with Aname's sexual fluids.
"Haa, haa, haa."
"Phew, pheew..."
Once they reach wise age, a slightly awkward atmosphere arises.
When I happened to look at Mahiru, our eyes met and we both looked away.
"Umm, maybe Shiina should go back to your house soon. It's a good time."
"That's right. Well... my legs are weak, so I'll rest for a bit and then go home."
"I, I see. I'm going to wash off in the bath then. You can come back at a convenient time."
With that said, he quickly retreated to the bathroom.
--Mahiru's point of view--
Mahiru stayed behind and made sure that Amane had gone into the bath, then picked up the masturbation aid that had been left there.
"This is... Fujimiya-san's semen..."
Inside the masturbator, there was a pile of semen that Aname had just ejaculated.
Mahiru scooped it up between her fingers and played with it, stretching it, making a squishy sound.
"It's really sticky. And... it has a strong smell."
I sniffed it. It had a pungent, fishy smell, but strangely it didn't feel unpleasant, and it made my head feel fuzzy.
"This, more..."
When you smell it, you feel like you want it endlessly.
"H-No, I can't. I have to leave before Fujimiya-san comes out of the bath."
If someone were to see me in a place like this, even Aname, a perverted gentleman, would be shocked.
I put the masturbator back in its original place and get ready to go home.
"...Ah."
When I was about to go home, I suddenly realized something.
"What should I do about this..."
Mahiru was at a loss when she saw a large stain on the sofa where she had been sitting just a moment ago.
