One day.
As usual, I was looking at the screen of an online auction on my computer.
I wasn't looking for any particular item, just browsing causally. The other day, I had just won a bid for a mirrorless single-lens reflex camera that I had wanted, and if I bought anything else, I wouldn't be able to survive as a single man living frugally.
Still, it seems that opening the auction screen as usual has become a habit.
My name is Kureha Kosuke, 30 years old. Single. Height 181 cm. Weight 74 kg. I did track and field and karate in college, so I'm on the slim side.
I'm a researcher at Yuuki Scientific Industries in Narashino City, Chiba Prefecture, and I'm developing inkjet heads for computer printers. We're in an age where 3D printers have just started appearing and it's now possible to create a variety of three-dimensional objects, but they're still expensive products that are out of reach for the average person.
Our company's products are quite popular, and because of my sociable nature and good looks, I'm often sent on business trips to sell them.
"Hmm..."
A certain product caught my eye.
It said, "One of a kind."
The thing is a solar-powered radio-controlled wristwatch that you can find anywhere, the name of the watch is "Perfect Sex". I thought it was a silly name for a watch and opened the detailed description.
The dial has hour, minute, and second hands that indicate the usual time. A small window for the date and day of the week is located on the right side of the crown. Incidentally, there is also a crown on the other side.
There are two small chronometers on the dial, one for centimeters (length and thickness) and one hand for a six-hour timer.
I tilted my head and read the detailed explanation.
"If you're skillful, you can use it however you like! This watch will guide you into the world of perfect sex. It's the only one in the world! Any woman will be captivated by you! I developed it, but I'm now 89 years old and no longer have any interest in sex. I'll give it to a young man who wants to have dizzying sex with a woman! I burned the blueprints, so it will never be possible to make another one like it!" it says.
The price, including tax, is 220,000 yen. For a radio-controlled watch, this is an exceptionally high price.
Completely waterproof, can be used up to a depth of 100 meters. Shockproof. Completely waterproof with a one-piece titanium structure that can be used in hot springs. By simply operating any of these functions, your penis and entire body will be completely covered in antibacterial properties, eliminating the risk of contracting a sexually transmitted disease.
No one was bidding. There were two hours left.
"..."
I stared at the watch.
And then, before I knew it, I had clicked on the "Bid Now!" button. As if my hands had moved of their own accord, I entered my credit card number, and my bid was confirmed.
And then, four days later, on a Saturday morning.
The apartment doorbell rang, and I got off the elevator to the sound of a voice saying, "You've got a delivery." However, there was no sign of a delivery person, and only a small box in the mailbox. It was addressed to me, but there was no sender's name or address.
I took the box and returned to the apartment.
I sat on the sofa in the living room and opened the box.
The watch was exactly as it had appeared online, housed in a beautiful wooden box that appeared to be made of finely carved teak.
There was an instruction manual written in English, and it explained in detail how to use the watch. I can speak a bit of English, so I can understand the contents of the instruction manual.
"If I could use any woman freely with just this watch, I'd have no trouble..."
I muttered to myself, laughing, as I looked at the instruction manual.
The manual includes the following information, written in red:
① Setup (PIN entry and activation)
② Ideal thickness and length adjustment (penis length: up to 25cm. thickness: up to 6.5cm diameter. glans diameter: up to 8cm. Can be adjusted depending on the partner)
③ Duration of erection and ejaculation (unlimited erection. Time from insertion to ejaculation. You can ejaculate as many times as you want within that time. Can be adjusted depending on the partner.)
④ The number of times you can have sex a day (unlimited. Completely antibacterial and pregnancy prevention functions included)
⑤ How to release the aphrodisiac (for women only. Pinpointed electromagnetic waves that make any woman they set their sights on addicted to sex. Within 10 meters, it can be adjusted easily from a weak 0.1 to a strong 5), etc.
And at the end it says "bonus".
* Bonus: Use this function only with women you really like. During slow sex, rotate the dial ring clockwise twice to level 0.5. Press the right crown once and whisper to the woman what you want her to do. It's a kind of subliminal effect that will permanently imprint itself in the woman's brain, allowing her to do whatever you want her to do. To release it, rotate the dial ring counterclockwise twice and press the right crown once.
I immediately followed the instructions and entered my eight-digit PIN code, then used the included needle-thin pin to press the hole in the back cover. Beep-Beep-Beep, I heard eight small beeps. The hands of the watch, which had not been showing the correct time until then, moved automatically to match the current time.
"Wow..."
I put the watch on my left wrist with some admiration and proceeded to step ②.
"Is it worth the price? Or is it just a fake..."
I thought it was just a normal watch, but I decided to follow the instructions and try to operate it.
I pulled out the crown on the right side to the second position, and from the "normal" position, I adjusted the thickness to 4.5 cm. and the length to 18 cm, then put the crown back.
Suddenly, my dick, which had been in its normal state, started to rise up.
"Ouch, ouch!"
I grimaced and cried out as my cock was so hard it was about to burst through my pants. My cock was so hard it was caught in my pants and it looked like it was going to break.
I hurriedly stood up, quickly unbuckled my belt and pulled my pants and underwear down to my knees. My cock, freed from my underwear, had large veins and was thicker and longer than I'd ever seen before. It was so erect that it was pointing upwards and touching my belly button.
"This is no good! I have to let one out!"
I grabbed my cock, the veins of which were bulging, and stroked it violently.
After about 10 strokes, my cock reached its limit.
"Oh no!"
I placed the mouth of an empty plastic bottle on the table over the tip of my cock.
"Uuh! Kuku! Aah!"
I closed my eyes and climaxed with a thrusting pleasure. With a bang, bang, my urethra widened, and a huge amount of semen spurted out of my 18cm cock.
"Ahhhh! Ahh! Ahh!"
The semen that spurted out of my dick hit the bottom of the plastic bottle, making a "splat! splat!" sound.
"This... I can't believe it..."
I stared at my cock, which had ejaculated violently. The semen I had ejaculated had accumulated in the plastic bottle, it was cloudy and thick. I'd heard that normal semen is at most 2 cc, but the amount I had ejaculated was at least 5 cc.
This was the first time I'd ever ejaculated such a large amount of semen.
My cock had grown surprisingly large, and even though I'd ejaculated a huge amount of semen, it showed no signs of shrinking. On the contrary, it remained rock hard.
Wait a minute. I'll try setting it too normal.
I set the crown of the watch to "normal." Then, as if by magic, my huge erection subsided, and my dick returned to its normal size as if the air had been released.
"Wow, I might have won something incredible..." I muttered to myself.
A watch called "Perfect Sex" that I had acquired by chance.
Staring at my cock that had calmed down, I put on my underwear and pants, cleaned up the copious amount of semen I'd ejaculated into a plastic bottle, sat down on the sofa and read the watch's instruction manual so thoroughly that I knew it by heart.
According to the instruction manual, this watch was the very definition of "perfect sex."
When I wear this watch on my wrist, if I approach a woman I see nearby within 10 meters and press the left crown once, a weak "Aphrodisiac Electromagnetic Wave" will be emitted. The strength of the "Aphrodisiac Electromagnetic Wave" can be selected from 0.1 to 5. If the "Aphrodisiac Electromagnetic Wave" hits the targeted woman, she will want to have sex with me and will be captivated by me on the spot.
From the time the "Aphrodisiac Electromagnetic Waves" are applied to the woman until the "Aphrodisiac Electromagnetic Waves" are turned off after sex, the woman will have no memory of the time. The instruction manual states that it is recommended to use it for internal ejaculation, since it is fully antibacterial and has pregnancy prevention functions. In other words, it means that I can do it raw as much as I want.
*However, if I want to leave a woman's memory of my face and the great pleasure she felt during sex, to make her remember having sex with me and want me to hold her again, I can leave her exposed to 0.1 "Aphrodisiac Electromagnetic Waves".
Before having sex, operate ② to set the length and thickness of my penis to my liking. Operate ③ to make my penis fully erect, and I can do whatever I want with it, from blowjobs to insertion, and piston-like movements. I can enjoy doggy style and even standing sex. I can adjust the time until ejaculation in advance.
④ is the operation that decides how many times a day I will have sex with a woman. I set it to infinite. I'm 30 years old and have plenty of energy. Four or five times is a piece of cake.
If I pull the left crown out one notch and turn it to the right, the sperm will die 0.01 seconds after ejaculation. This is apparently a pregnancy prevention function. If I turn it to the left, the sperm will survive for 24 hours, and there is a high possibility of pregnancy.
I'm a pretty shy guy, but if this instruction manual is correct, then I can have sex with any woman I set my eye on all day long.
"There's no reason not to try it..."
The desire to have sex with a woman immediately rose in my heart. Even though I hadn't operated the watch, my dick started to swell up.
