I've been lying on the rocky beach for half an hour. The morning sun was just gaining strength, and a pleasant coolness was blowing from the May sea. "It's time to take a plunge," I thought and propped myself up on my elbow. At such a time there were no other people on the shore; there were still three weeks left before the summer noise and din. Nothing foreshadowed the whirlpool of unusual events into which I was about to plunge in just a few minutes. But just at that moment my ears began to ring, and the air around me began to tremble and shimmer.
The first thing that came to my mind was that I was suffering from sunstroke. But the sun had barely risen and a rather cool breeze left no chance for this hypothesis. Meanwhile, the air stopped flickering, a gray haze appeared, and not far from the place where I was located, a certain vehicle literally began to appear out of nowhere.
It looked like a metal bubble with a transparent cabin, which hovered a meter from the ground. Two silhouettes were visible inside - one, judging by the outline, clearly belonged to an adult, and the second to a girl or even a girl, but their faces were not visible because of the smoke. When it dissipated, I rose from the stones and took a few steps towards the unexpected guests. It now became clear that in the vehicle there was a bearded man of about forty and a girl who looked to be about eighteen years old.
With a quiet rustle, the cabin opened, and the device made a buzzing sound and sank lower, almost touching the stones with its iron belly. The girl immediately attracted my attention. Her young pretty face and blond curls could not leave me indifferent, and her large breasts, which were covered with a white T-shirt with a wide neckline, attracted my attention. When this amazing creature smiled affectionately, I felt joyfully warm inside, and a shiver of excitement ran through my body.
- Hello! - said the stranger. - My name is Gleb. And this is my daughter Alice.
Alice laughed at my confusion and greeted me with a wave of her hand.
"Uh..." I said. There wasn't enough imagination for more.
- What is your name? -- Alice's voice rang melodiously like bells.
"D-d-dima," I said with a naughty tongue, stuttering.
"Well, Dmitry," Gleb began to explain. -- Judging by your amazement, the principle of antigravity is not familiar to the scientists of your world. The true structure of the universe, consisting of billions of parallel worlds, is also unknown to you, right?
"You're absolutely right," I said. - So you... are aliens?
Then it finally occurred to me to secretly pinch myself to check if I was dreaming.
"In a sense, yes," Gleb nodded. -- There are many Lands, and each of them has its own traditions and norms, rules and prohibitions. It is very interesting to explore them, but the secret of traveling between worlds is discovered only in some of them. But we honestly would like to ask for your help. The fact is that Alice is studying at the university and is now preparing material for coursework in xenology. And I'm on vacation and helping her.
Alice nodded and looked at me with a smile. I could have sworn there was a mischievous sparkle in her eyes.
"So," Gleb continued. -- Alice explored many traditions in other worlds. She decided to choose the most unexpected of them as the topic for her coursework. I want to warn you right away that much of what I say may shock you.
- Speak. I'm interested.
- In general, this is the situation here. Various prohibitions and taboos of a sexual nature operate in many worlds, sometimes they take the most bizarre forms. But only in yours there is a dual situation. The fact is that in almost all media you have a cult of sex. Alisochka and I specifically looked through your TV channels and analyzed computer networks - most of the requests are related to sex.
Gleb stopped for a second, watching my reaction. And I didn't know at all how not to react, so I stood rooted to the spot.
"But at the same time, in your world specifically, there is a very unusual deviation," Gleb decided to finish the thought. -- With such a comprehensive interest in sexual relationships, family relationships, so-called "incest," are completely prohibited; free love and public sexual contacts are categorically discouraged. You seem to be frozen in a half-position. Hence, according to the conclusions of many scientists who have studied your Earth, there is almost constant sexual tension that haunts the inhabitants of this world.
