The other sister smiled, giving me a short yank with her arm, "We don't need to talk to understand each other."
Without a moment to detangle, she was dragging me to the treehouse, her hand reassuring but firm. She was very graceful and practiced in her walk. "Understand it like that," she called down, her voice strong. "Step here... take hold of this branch... drag your body up..."
I acted the same way as her, which was the same way she had done to me.
Without waiting for a response, she had already gone on top of me, her nightie flying up as she reached for the next hold. I took a quick look at her and I could see that she was not wearing any clothes.
Everything was quite dark and colors were changing a bit, but I could still see the outline of her pussylips, the subtle curvature of her thighs. I almost missed breathing. Was she aware that I was staring at her? Not likely. She probably saw me as one of those wild, untamed guys who were lost and copying her gait like a willing student.
Mary's sister grinned down at me, her eyes twinkling with delight. "Yo, Mary! Look at that! He's catching on! He's clever!" She sounded warmed, almost proud, like she'd just given a new lesson to a puppy.
Mary, with an eye full of doubt, followed her tone, "Sister, you're seeing it that way only because you want him to be under your control like some pet. Don't take it too far." A note of warning mixed with an ingredient of curiosity, and maybe an amused trace, could be felt in her voice.
Rather than giving me an answer, her sister only laughed softly; then, as if I were a small boy, she passed her fingers through my hair. "Oh, come on," she said.
She got a little nearer, and the feeling of her warm breath on my ear made me shiver. "He is so cute.. just like a small child..?" She beamed, but she looked serious - as serious as a play.
Mary's gaze met mine directly, and her face gave me no clues about what she thought. Breathe in, "I'm watching you," she said very quietly but firmly. Nevertheless, she was not giving me a threat; instead, she was making me a promise.
I felt a thrill run through me as I returned her gaze. Yeah, this was going to be a blast.
By looking on the one hand at the treehouse and on the other at the pictures that were hanging on the walls (maybe family photos?), I didn't recognize anyone from the pictures, but at the same time, they were framed in a way that showed these two were either sentimental or at least not completely cut off from their past.
There was a mattress on the floor that seemed both wrinkled and as if it had been used a lot, which to me was a sign of at least some nights under the stars or some lazy mornings with tangled sheets.
Mary, seeing my expression as I looked at the things in the treehouse, laughed and said, "He must be so confused to see all these weird things at once."
Her sister gulped some water from a bottle, then she flipped it over and held it up for me. "Drink...," she said, but didn't give it to me. Instead, she came closer, and her body was almost touching mine. She said, "Put your mouth here... aaaa...," gently tilting the bottle.
Not really knowing what to do, I complied. She slowly and not all the way, poured the water into my mouth. I paused for a moment before showing that I didn't know how to do it, so the water ran down my chin. I demonstrated my large surprise at this strange sensation.
Mary was not amused. "He is a fool. Shut your mouth."
Her sister just shook her head and sighed, "I must be patient while I teach him..." She spoke with a tone of patience, as if she were talking to a kid or with a fascinating experiment.
Mary brought the bottle over, drank a lot from it, and then demonstrated it to me. "This is the way," she started and swallowed the liquid very dramatically.
"Do you understand?"
I enjoyed immensely the way they treated me—as if I were their object of curiosity and their project—this little game was intoxicating to me, and I was playing it really well.
This time, when Mary's sister poured water in my mouth, I swallowed it properly, making a small satisfied "ahh" for effect.
Mary's sister brought her hands together, and her laugh, like wind chimes in a gentle wind, filled the treehouse. "It's learned by him! I'm such a good teacher!" With her enthusiasm, she beamed at me, her eyes brightening as she softened her stare and leaned towards me.
She then pointed to herself and, slow and clear, said, "I am Veronica..." After that, she pointed at Mary and said, "And she is Mary."
It was then that I realized her name was Veronica...
She leaned closer and, silently drawing an imaginary line in the air with her finger, she explained it to me, "Call me... Ve... Ve... Ro...Ni..ca..." She spoke each syllable distinctly, watching me closely.
I behaved like a timid and wide-eyed savage, throwing a nervous smile at her and swallowing hard. Copying her, my voice shaking as I said, "V... Ve... Ro... Nica..."
Veronica was overjoyed. Next, she pointed at Mary, supporting me, "M... A... Mary."
To be sure, I looked at Mary, pointing with my finger at her and saying, "M... A... Aaary."
Once again, Veronica applauded, her delight sincere. "Very good! Look, Mary! He's so smart!"
Mary crossed her arms, smiling at me a little. "Yeah... he is not that terrible." Her voice was a bit skeptical, but the warmth in her eyes was unmistakable. She was beginning to recognize me as more than just a lost one from the wilderness.
I did not show it on my face and kept my expression inscrutable, feigned innocence with my eyes wide open, but in my head, I was already spinning with the exhilaration of what the future might hold. This was merely the kickoff.
A mattress was laid out to its full extent by Veronica, and as her figure sank into the comfortable material, she patted the area beside her, her fingers curling in a silent invitation. The move was unmistakable - lying down.
Mary's surprise shock could be heard in her words. "Sister, is it that you are really going to sleep with him?"
Veronica's face turned so red all the way down to her neck and she was so embarrassed that she couldn't speak properly. "Who said anything about sleeping with him? I want to find out if he is able to read our signs!"
She shot a look at Mary, but it was more a glare of the type that an actor uses when playing a child who looks at life in a new way and pretends to be the only one to understand it.
After a little while, I went over to her and gently dropped next to her on the bed. Her scent was like that of the sun on skin with a little flower mixed in.
My body immediately and excessively responded - my hard-on throbbed against the spur-of-the-moment rugged fabric of my leaf skirt. Anyone would be able to tell; as the fabric moved, the shape was there for you to see.
Veronica gasped for air, her eyes darted down for a brief moment before they went back to mine. What was between us was electric, dangerous, and she got it - this was going to be much more fascinating than what I had thought.
Mary's voice went even sharper and more strained as she advanced a step. "Sister... get away from him. He's horny. He might rape us!" Her words were filled with panic, and her stare kept flipping from both of them to the bulge in my leaf skirt, which was pretty obvious.
Veronica reddened even more, but she stood her ground. She picked her lip and said with a low but firm voice, "Mary, we are not sure of it. He could just be showing normal behavior to mate with females. They might not even be aware of it as a wrong thing." She sounded a little bit of wonder, trying to make friends with something wildly unfamiliar.
Mary gasped, her voice shook as she tried to get the correct words and make sense of them. "But... but... " she stopped abruptly, her fingers pressing into her palms, her knuckles turning white. Her eyes showed the emotion of fear, but alongside it was something different, a raw and unrevealed one. That was curiosity. That was the most reluctant and nearly a forbidden form of curiosity standing on the verge and pulled one side back to lean in and see what lies down.
It was at that point in time when the realization came to me: They are as unaware as I was first.
They haven't the slightest notion how "Stone Age" folks lived here. Nor did I when I first arrived here.
But their take on it was somewhat logical in a perverted way. For them, a man from the primitive period would be ruled by his nature only - seeing a female, getting a hard on, and doing it without thinking or feeling. Like animals. Like the rawest side of nature.
And somehow, I agreed with them as well. It made sense if you took away everything else - culture, ethics, layers of civilization that had been there for millennia.
The real Stone Age - survival and reproduction would be the only rules. Desire wouldn't be complicated by shame or rules or the burden of societal expectations. It would just be.
But this world - this reality - was nothing like that.
In this Stone Age Era, it was enmeshed in the layers of meaning, morality, love, longing, and the heaviness of what was "right".
Men were trained to see virginity as something sacred, to detach lust from instinct, to feel shame where there should be none. It was all so artificial, so far away from the raw, unfiltered survival rhythm.
And still, we found ourselves here.
A woman from the future, a system that cannot be explained, and me - a man confused between time and space - all of us thrown into a version of the Stone Age that seems more like a break in reality than history.
It was neither the past. Nor the future. It was a crash, an area where time's rules have been twisted, where the worlds that should never have met are now intertwined.
A time machine by 2050? Not likely. A "system" that bends the laws of physics? Hardly conceivable. Yet, here I am, lying next to Veronica, with my hard cock.
Veronica moved a little and said with a voice that was abrupt and business-like, though her cheeks were red, "Mary, bring me a condom."
Mary was so shocked that her eyes grew larger than usual, "What?! Sister, have you lost your mind?!"
Veronica's red became even more intense, but she didn't drop the point, "Mary, you are the one with the dirtiest mind. Don't you know that I am a biologist?" She looked at me, and the next words that came out of her mouth were of seriousness and almost like an academic nature, "I want to find out if there is something unusual in his sperm - if his body produces more protective antibodies than ours."
Mary put her arms over her chest and said with a voice that was very close and tight, "But we can just do his blood test! You don't need to - " She stopped, as if the words were too scandalous for her to utter.
Veronica refused to agree. "Blood test won't give me the answers I am after. I want to know if his sperm is more viable than people from our timeline. You remember the reports—after the glaciers melted, the air got polluted, and the virus that didn't just kill people,"
"It made them infertile. Even with the government's population incentives—offering care for parents and children—people still weren't able to get pregnant. That's the reason why they started the Exodus Project and sent all those people here. But what if the virus came with them? Then there's no reproduction even here in this timeline?"
Mary looked as if she had just seen a ghost. "So it means... that fertility issues might still be a problem for the people in the fortress? Even if we have put our timeline behind us?"
Veronica confirmed with a nod. "Yes, it is possible. And if that is the case, the only way we can figure it out is by understanding why. It could very well be that his body has the answer."
Mary was staring at Veronica, then at me, and her fingers were nervously scratching one another. "But ....?" Her voice was extremely low, and her throat seemed to be clogged. "I... I am not doing it with him. You decide."
Veronica didn't look away. Her tone was calm, almost detached, although there was still a slight pink color on her cheeks. "Mary, it is the only way. The only way for science. For the coming generations." She was silent for a moment and then, after a quick glance at me, she said to her sister, "I know it is hard, but be brave."
Though Veronica's assertion was quite straightforward and assertive, there was something else apart from that being conveyed - something that was not stated but could be heard like the crackling of a radio between the lines. "It won't be necessary to sleep with him... He might just be done with a handjob," was the unspoken part of the sentence.
The treehouse seemed to get smaller with the shrinking of the space between us and the suffocating feeling of air that the presence of an awkward silence brought. Mary's chest heaved, her eyes were round from a mixture of amazement and something else, something darker, something that was almost like curiosity. She didn't argue; she didn't utter any refusals. She only stood there and was twisting together her fingers, her thoughts racing at a high speed.
However, I am not sure that they thought positively because in my head, it was a complete mess as well.
Supposing they find my circumcised cock? Would they then understand the truth—that I am not some barbarian from the past but rather someone from their time or close to it? Would that be the end of everything?
After a while, Mary spoke, her voice weak and trembling with emotion: "But, sister... I am still not convinced that it is a good idea. What if he thinks that we want to mate with him and then... he might try to rape us!"
Veronica was not sure herself and was biting her lower lip. "Well,... perhaps, you are right. We can't take any risk," she said. Looking at me, she was full of contradictions, "I don't really feel like it... But he doesn't seem that bad, you know?"
Mary's voice becomes more and more cutting, her terror transforming into revulsion. "He is evil! He is terrible! Who knows if he's even washed his body in years? And then what if he carried some disease or virus? For all we know, he might have AIDS!"
