Track 13.5: The First Penis Masturbation

“P-Penis masturbation……?”

Reading a certain word in the title of a hypnotic voice recording package reflected on my screen, I gulped down my saliva. My name is Tatsumi Nanami. I am a normal girl that you can find anywhere. That is why, naturally, I did not have a penis on my body.

Though I did not have one, I had some interest in it. If I had to say, I was more interested in how to masturbate with it. Just how would it feel like to masturbate with a penis? – such was the extent of my interest.

“……this is a voice recording work just for you, to give you a simulated experience of how a man masturbates through hypnosis, is it?”

The hypnotic voice recording community brought together people with all sorts of tastes and hobbies, assembling together an extensive variety of genres. In order to try out new genres, I also looked through the works of different groups I normally didn’t check, and what I finally arrived at was this [First Penis Masturbation] work.

“No…but…even if it’s hypnosis, there’s no way it could……”

There’s no way I could suddenly believe that it could give a simulated experience of male masturbation. Since my memories during hypnotic masturbation become rather fuzzy, I wanted to do something so that I could check what’ll happen to me but……

“Ah, that’s right.”

Isn’t there a simple method to objectively see my own state? That’s right, it’ll be fine as long as I record it with my smartphone’s camera. Now that I think of it, in the past I also recorded myself during hypnotic masturbation.

It was a little embarrassing to be recording myself while masturbating, but I was more curious about what would happen to me, so it couldn’t be helped. Alright, now that it’s decided, let’s immediately download it. I have to determine the authenticity of this hypnotic voice recording. While I’m downloading it, I’ll set up my smartphone so that it faces my bed…….okay.

As I prepared for the voice recording, I cleaned up the surrounding area. However, even though I was doing all this preparation for it, I still felt doubtful about this hypnotic voice recording. If a penis suddenly sprung out, it’d start reaching the level of an illusion. I also should’ve built up quite a bit of resistance against hypnosis, so things probably won’t get that bad.

◆◆◆

[——warmth is gathering throughout your body. It is steadily, steadily flowing towards your important place.]

“Fuaa……ahh……………AH……ahhh……ah…………….”

Hot. Just below my belly feels hot. Something is gathering from my entire body. It was at a comfortable temperature, as though I were being enveloped in steam. Within that warmth, it felt as though my body was going to melt. The sensation of my body gradually became more and more fuzzy.

[That energy will now help in making you feel good. At the very end, that warmth will concentrate on a single point on your body and make a symbol of pleasure.]

“Haa…….haa……naa…………….nn……”

The warmth that had been flowing from my entire body suddenly concentrated onto a certain spot, gathering towards my clitoris. My hips reflexively rose, and a longing voice leaked from my lips.

[Come, now start to imagine a man’s member, think of the shape of a penis. You will make as strong and clear an image that you can inside of you.]

When I was told that by the voice, images of penises started to float inside of my head. Regardless of my will, my brain started to form an image from the memories of my life experiences all on its own.

[Look, try touching your lower half with your hand. You can already feel a penis. That is an incarnation of your desire, it is your sexual desire itself. Can’t you see it? Can’t you feel it?]

“Uwah……y-yes……I can see……the penis……I can feel……the penis……”

When I looked towards my bottom half, before I realized it, a pulsing member that twitched strongly was there. The place where all the energy flowing from my body gathered stood excitedly. It was a penis, something that I had only seen in textbooks.

[Now, with this the preparations are complete. Well then, I’ll now teach you how to masturbate with a penis. Properly follow what I say, and let’s turn you into a Monkey-san who can only think about stroking your penis, kay?]

“A-Ai’ll……ai’ll bekyum one……! Ai’ll bekyum…a monkey……!”

From my previous state only moments ago where the inside of my head felt as though it were filled with mist, my brain slowly changed completely in order to focus on something. I rearranged my rough breathing as I waited for the next instruction.

[First you will stroke your penis by yourself. Using both hands, firmly, but gently, grasp the shaft, and slowly move them up and down.]

“Yes……I will……stroke my penis……”

I did not have any experience in touching a penis, but my hands entwined the rod in a surprisingly natural manner. Squeeze, when I had completely grasped the penis, the tip momentarily quivered pleasurably. That pleasure spread like a ripple, and I also quivered.

And then, like I was told, I slowly started to move my hands. Starting from the base, I stickily moved them up and down as though I were squeezing something out.

“Nn nn———-hauu……♥ OHH——Hooh……♥ Nyuu———fuu……♥”

Just around the time I started to get used to it, the way my hands moved started to change. They went towards the tip of the penis, holding it as though they were trying to irritate it, and then dropped to the base of the penis in one stroke. The rush from the new stimulus caused me to involuntarily thrust my hips forward.

“……OH♥ OHOOooh……♥ Stwoking mai penishh….nnn♥ I-Ish moar painfull dan I foughtttt……♥ Hoohh♥ A-Ai kyan’t show dish shameful wook to anyoneeee……♥”

Stroking a penis was a far more dumb act than I had imagined. However, it felt even better than that, and I could not stop my hands. On the contrary, the more I thought about how unsightly I looked, my brain became paralyzed by an inexplicable pleasure. My facial expression crumbled in a slovenly manner, and I let out a revolting smile.

[Ufufu……it’s been prepared quite well. You should be feeling something now, aren’t you? Look, that thick, male impulse is boiling up from within you.]

“AH……♥ Ahhhh……♥ Hahi♥ I kyan…feel ish♥ Sumting…ish, haa……♥ Shumting ish kyummingg♥ OH, OH, OH♥”

I noticed it after being told that by the voice. Something was welling up from within me, something that was sort of irritating, sort of yearning, something that I could not understand too well. Even now, it was trying to jump out from inside of me.

[That is——semen. A fluid that men leak out when they feel good. Having grown a penis, you are also the same. When you reach the peak of pleasure, it will start to spurt out from your penis of its own accord.]

“Shpur-, shpurt sphurt♥ Ai’ll shpurt it outt♥ Sheemen♥ will kyum outt♥”

Creak, creak, creak. The sound of the bed creaking grew quicker. Unaware, I had started to move my hands up and down far more violently than before. Without comprehending what I was doing, I did nothing but indulge in the pleasure. If I just continued to stroke myself off like this, I’ll be able to release this irritating feeling that was swirling inside of me.

“OH, OH, OH♥ NN, NN, NN♥ Ahh♥ Come♥ Come♥ Something ish kyumming♥ OH♥”

Every time I drew my hands down to the base, smack smack, the sound of flesh colliding was emitted. Stroking myself felt too good, and my movements steadily became more and more intense. I could tell that something was rising up. I could tell that something was about to rush out. Within me, something was——–

[———come on, let it out-]

“AH♥”

Fwop, my field of vision was overturned. While still making a shameful ahegao*, my body bent backwards to its limits.

*T/N: Ahegao = a face made during orgasm

“OHOOOOOooOOOOOooooOOHHHH♥”

The pleasure exploded inside my penis and turned into semen, spurting out. The penis struggled violently within my hands scattering a white fluid in the surroundings.

“OH, OHHhhh……♥ Nn nn♥ NNnnnnnnnnnuuu♥ Ha, haa, haa♥ Ahiih……♥ Ah♥ Aeeaaa……♥”

It was a momentary affair. As though the penis was satisfied, it became obedient and feebly lay on my thighs. At times it would spurt out some residual juices, causing me to twitch. I could only stare blankly at the violent pleasure that had passed like a storm.

◆◆◆

[——you know it’s still not over yet, right?]

“Yesshhhhh♥”

As my hips trembled while I was submerging myself in the lingering waves of pleasure, I once again heard that voice. No matter what sort of state I was in, as soon as that voice spoke to me, my entire brain would react to it.

[My goal is to imprint the pleasure of penis masturbation onto you, and turn you into a penis-crazed pervert. There’s no way I could let things end after masturbating just once, right?]

“Ah, ah, ah♥ N-Nyo wayy♥”

I didn’t hear about something like that. I don’t want to become penis-crazed. The faint bit of me that barely remained rejected that. My consciousness already felt like it was about to fly away from the ejaculation earlier, so there’s no way I could stand any more pleasure than this. And, I’ve heard that a penis gets smaller after ejaculating once. That is why it cannot ejaculate any more. Thinking that, I turned my eyes toward my lower half and swallowed a breath.

“……hiih……w-why…has it gotten bigger again……?”

Standing there was a penis that, rather than getting smaller, had swelled up vigorously to become even larger than the first time I had masturbated with it.

[Fufu, your penis is specially-made. Even if it ejaculates several times, its excitement won’t lessen any more. Every time it ejaculates, it will steadily grow, until the very end where it might just take over your brain itself.]

“N-Noo……noo……!”

I absolutely don’t want to become controlled by this repulsive thing. Even though that’s what I was thinking, my hands were attracted by the penis, and it took everything I had to restrain them. Even though I mustn’t ejaculate, my body was once again seeking out that pleasure.

[You should just feel good and let your penis ejaculate. It’s simple, isn’t it? Now, why don’t you empty your head, and lose yourself to your penis?]

“Ahh, ahh♥ Nyoo♥ I-I…amm♥ ah, ah, ah♥”

The words that were whispered into my ears easily penetrated into my head to a terrifying extent. That sweet temptation corrupted my heart all too easily.

[——–Loo~k, completely abandon yourself to the penis.]

“AH, AH, AH♥ Punyuuuu♥ Ai wiyuuu♥ Ai wiyuuuuuuu♥ Ai’ll yuush ebweyting inshide me to stwoke maishelb and shoot outttt♥ OH♥ Ohnyuuu♥ Ah, ai’ll bekyum an emptee hyeaded monkeyyyy-shannn♥”

And then, my heart submitted. To this voice, to the penis. Both my hands were already firmly grasping the penis and had desperately resumed stroking it. It did not take very long until the second ejaculation occurred.

“OH♥ OHOOooooOOooohh♥ Upyuu♥ Nyuu♥ UuuuUUuuuuuUUuu♥ NN, nn, nn♥ Nnheaaaaaa……♥”

Like earlier, the penis drooped feebly once, but after scattering about the remaining juices it soon regained its vitality. It became even more powerful than before, and was a size larger, as though it was stealing energy away from me.

[*giggle* I’m also happy that you’re becoming honest to your penis. Now then, I’ll teach you another way to make your penis feel even better. Focus your consciousness onto my words.]

When I was told that, I fell into the illusion that an eagle grip had grabbed onto my brain, forcing my ears to focus onto her. I cannot defy this voice. Because I know that this voice will give me pleasure. I end up following whatever this voice tells me to do.

[——a hole. The penis is entering a hole. A hole that is close to you. As long as your penis can enter it, anything is good. You cannot help but want to thrust your penis into that hole. You’ll irresistibly want to violate it, ravish it, and shoot semen into it.]

“Uu, uwahhh♥ Holeee……♥ Holee……♥ Want to…put it in♥ Can put it in♥ Violate…hole♥ Uu…UuuuuuuUUU……♥ Hole, holee♥ Penishh♥ Shooooot♥”

Snort, snort, my nasal breathing grew rough. I wanted to put it in right now. In the blink of an eye, the inside of my head was completely filled with the thought of putting my penis into a hole. I got up from my bed, and look around my surroundings.

——knock knock

At that moment, I heard the sound of knocking from my room’s door. Following it, a click sounded as the door opened.

“Onee-chan, I came to return the manga I…borrowed……”

The one who entered the room was my little sister, Mutsumi. While holding a manga in one hand, she looked in my direction and stiffened.

It’s a hole. Seeing Mutsumi, that was the first thing I thought. Before I realized it, I was straddling Mutsumi in the hallway in front of my room.

“HIiiiiiiiIIIiii…O-Onee-chan’s gone w-weird againnn!”

I firmly held Mutsumi down as she desperately wriggled in an attempt to escape. And then, in a mostly unconscious manner, I grabbed Mutsumi’s pants and forcefully pulled them down together with her panties.

“Hyauun!?”

“Ah, ahaaah♥ Holeee♥ Holeeyyyy♥”

Together with a cute scream, Mutsumi’s butt jiggled as it appeared in front of me. In that chasm were two faintly twitching holes. I heard something snapping inside of me.

“Ahh……AH……AaaaaAAHHH♥ HOLEEE♥ MATEE♥ Fuuu, fuuu♥ Lesh mateeee♥ Kyum, ai’ll impwegnyate youuu♥”

Without a hint of hesitation, I shoved my penis into that hole. I didn’t know which one it entered. My hips moved of their own accord. Right now, I was being completely controlled by the penis. My body, my thoughts, my desires, everything.

“Wait, Onee-cha-, ah, ah, wh-what are you……!”

“Hmph, hmph, hpmh♥ Nn, nn, nn♥”

Slap, slap, slap, squelch, squelch, squelch

The sound of my body striking against Mutsumi’s butt echoed inside the corridor. I could not stop the movement of my hips. A far greater pleasure than that obtained from stroking myself assaulted me.

“OH♥ OHhooohh♥ Uryaa♥ Orya♥ Orya♥ I kyan’t forgib youu♥ fooaa wiggling such a butt awoundddd♥ Dish bad butt dat shaduces Onee-chann♥ Like dish♥ OH, OH, OH♥ Hmph♥ hmph♥”

“S-Seduce, you say……! You’re the one that suddenly……! Ah, w-wait a sec, stop it…already! Onee-chan, wake up!”

Mutsumi seemed to be saying something, but her scream just made me even more excited. Firmly holding onto Mutsumi, the speed at which I banged my hips against her increased. I felt the sensation of something welling up. I’ll shoot. I’ll ejaculate into Mutsumi.

“AH♥ AAaaaAAaahh♥ Kyum♥ Kyumminggg♥ OHOH♥ Y-Youu♥ Y-Youuuuu♥ Ai’ll impweg♥ Impwegg♥ Impweee———Nnn HooooooOOooOOOOoOoooOOOoohhh♥”

And then, I finished grandly inside of Mutsumi. Semen that wouldn’t stop flowing. It was as though I was shooting everything that was inside of me. I couldn’t resist this pleasure.

“OH, OOoooohhh……♥ Fugiiihh♥ NNnmuu♥ Uu, uheeaaaaaaa……♥ Aheeaaahhhh……………♥”

I became unable to support myself, and powerlessly collapsed on top of Mutsumi. Right before I lost consciousness, I could hear the pleasant laughter of the voice.

[*giggle* Al~right, a penis slave is complete.]

◆◆◆

[Uwah……y-yes……I can see……the penis……I can feel……the penis……]

“Ahh, ahh, AWAWAWAWAWAWAWAWAWAWA……-!”

About one hour later, I was sitting in seiza while still naked, being made to watch the video of my masturbation. Next to me was Mutsumi, who was looking down on me in an imposing stnace.

After that, when I recovered my consciousness, Mutsumi drew close to me with an incredibly threatening attitude. It made me wonder just what sort of play I had done this time. Every time I ended up dragging her into it. According to what Mutsumi said, I acted as though I thought I had grown a penis and was behaving correspondingly.

Even if it was me, there’s no way I’d have such a stupidly off impression. I had a video taken by my smartphone, so I figured we might as well check it together. Me saying that led to the current state of events.

[……OH♥ OHOOooh……♥ Stwoking mai penishh….nnn♥ I-Ish moar painfull dan I foughtttt……♥ Hoohh♥ A-Ai kyan’t show dish shameful wook to anyoneeee……♥]

“UWAHHHHHHHHHHHHHHHHHHHHHHHHHHH!!”

I held my head while crouching on the spot. I simply could not look directly at it. In the video was the image of my desperately raising my hands up and down in the empty air. Mutsumi was also watching that recording with an expression that displayed disgust that came from the bottom of her heart.

[Shpur-, shpurt sphurt♥ Ai’ll shpurt it outt♥ Sheemen♥ will kyum outt♥]

“S-Stop ittt! Stop it alreadyyyyyyy!!”

The me inside the video was curving her body with all her might while squirting. She hadn’t grown a penis, and naturally she wasn’t ejaculating either. She was being completely manipulated by the hypnotic voice.

[AH, AH, AH♥ Punyuuuu♥ Ai wiyuuu♥ Ai wiyuuuuuuu♥ Ai’ll yuush ebweyting inshide me to stwoke maishelb and shoot outttt♥ OH♥ Ohnyuuu♥ Ah, ai’ll bekyum an emptee hyeaded monkeyyyy-shannn♥]

“Haha……AHAHAHAHAHAHAHAHA……HA……haha……”

The air around us grew heavy as we watched the sight of me shouting such a crazy thing while making an ahegao in the video. All I could do was laugh now. Eventually, the video approached the time at which Mutsumi entered the room.

[Onee-chan, I came to return the manga I…borrowed……]

Upon seeing Mutsumi as she entered the room, I attacked her with an incredible momentum, looking almost like something from a horror film. Following that, it was easy to tell what was happening in the hallway in front of my room from the slapping sounds. Since it was filming with the bed at the center of the video, you could barely see the two of us, but the sight of my back as I assaulted Mutsumi was firmly reflected at the edge of the screen.

[OH♥ OHhooohh♥ Uryaa♥ Orya♥ Orya♥ I kyan’t forgib youu♥ fooaa wiggling such a butt awoundddd♥ Dish bad butt dat shaduces Onee-chann♥ Like dish♥ OH, OH, OH♥ Hmph♥ hmph♥]

“…………..”

“…………..”

Squelch squelch. We watched as I made pitiful noises and swung my hips, that had nothing there, against her like an idiot. Mutsumi put down the manga in her hands and silently left the room. Left behind in my room, the sound of my voice as I climaxed in the video echoed fruitlessly.
