With a low huff, her waist rose orgasmically as she reached a powerful climax. Her pussy twitched in bliss, providing me with another wave of sweet fluids. She might have been more excited than before because her twitching lasted for several seconds, small moans escaping her lips.
The sole concept of making my sister reach such a high in pleasure finished me too. I came together with her, my hand rubbing my glans hard to improve the pleasure. Her mouth was still full of my balls, increasing the stimulation further.
We stayed in this position for a few moments, appreciating the pleasure rushing through our bones. Finally, she released my flesh to pant lightly, her hips touching the soil of the cavern again. I removed myself from her, sliding toward her lower body.
There was nothing like cumming together with an inexperienced voyeur teenage girl. One more cross in my checklist.
Ursi was still a bit out of it so I placed myself in the most interesting spot, in front of her vagina. It was still shivering a little, a small quantity of juices flowing out of it. I opened her lips with my fingers, witnessing her lewd flesh in its post-orgasmic state. It was pleasant to see how strings of fluids linked the left and right parts of her inner cunt, creating a nice erotic view. Her pleasured female smell also filled my nose, and I was hard again without doing anything.
However, my eyes focused more on a specific part of her insides. There was a thin membrane that separated her outer twat with the deeper reaches. Despite clearly pleasuring herself often, her hymen still stood untouched, maybe because she only usually touched herself externally, without putting fingers inside.
Come to think of it, she was fourteen this cycle. This meant that, from the next cycle, she would be considered an adult, allowing any man to mate with her. First times were still considered special even in this prehistoric world. Each cycle, our tribe would have around five children who needed to be “initiated”.
For boys, it was simple. They would designate experienced women to teach them how to mate. If the boy, who was now almost a warrior, had a preference, he could choose a specific woman for his first time.
For girls, it was a bit different. It seemed that even here, taking a girl’s first time was a bit exciting for men. As such, those who wanted to take a girl’s first time would volunteer for her initiation. From those, a hierarchy would be established based on their actual position in the clan. Stronger warriors were at the top, while newer or weaker ones were at the bottom. In other words, if the strongest warrior in the tribe wanted to deflower a girl, he was certain to get that right. As for lower-ranked warriors, they could only hope no one higher ranked aimed for the same girl.
Back to our current situation, all of this implied that some random dude would take my sister’s virginity soon. There was no way that was acceptable. If she had to lose it, it might as well be from me!
I checked my dick’s size, comparing it to the position of her virginal membrane. Good enough. Fortunately, I wasn’t that small in this world, and that still showed even at my age.
While Ursi was still recuperating, I decided to do the ultimate move a man could do: combo dual losing of one’s virginity! Don’t be upset, Ursi, because I’m giving you my first time too!
I aligned my waist to her crotch, opened her legs wider, and positioned to tip of my cock right in front of her naughty hole. There was no need to hesitate. I wasn’t that kind of pervert.
With one large thrust of my hips, I inserted myself into her, tasting a woman’s pussy for the first time of my life. I pierced her hymen in one go, not leaving her the time to react to my act.
“Ah…! Ack…!”
Right as my sister groaned in pain, I felt the exact opposite sensations. Her wet and warm flesh extraordinarily enveloped mine, pulsating around me, and the sole idea of penetrating a girl for the first time would have made me come if I hadn’t done so barely a minute before. My tool felt the best there, and I wanted nothing more than to stay like this forever, with her contracting cunt stimulating me.
Ursi raised her upper body to check what was going on, and her eyes widened when she saw I was mating with her. She froze again, pain in her expression, and was unsure about what to do. I still didn’t want to break the charm by talking, so I used perverted gaze communication again.
I first made eye contact with her, glanced at the hole in the wall, back at her, and then at our point of connection. I did this a few times until realization appeared on her face. My meaning was simple.
The voyeur act that excited you so much before is now being done to you. You can be a voyeur of yourself!
She shook at this great philosophical revelation. In my previous world, this was called point of view sex, something a great many people enjoyed. Her breathing accelerated again as arousal soon replaced the pain of her deflowering. It also probably helped that she didn’t feel that hurt from the coitus since I wasn’t very big yet.
Ursi’s gaze dropped as she focused on the part where I was penetrating her, her face flushing with excitement again. Now that she was more stable, I slowly started to move inside her. Damn did it feel amazing! Her folds squeezed me on each passage while her walls released another wave of warm pussy juices, lubricating our act. I was now having sex for the first time in two lives, and the elation was just as great as when I went down on my first pussy ever.
With a lewd squelching sound, I increased the pace of my strokes inside her horny cunt.
