She carefully carried a dozen rabbit pelts up to the round, thatched hut. With her arms full, she pushed the leather door aside and set the pelts on the floor just inside so she could push herself up into the room. Two beeswax candles made the room only slightly brighter than the almost-full-moon nightscape outside, but she could hear a clink of glass on the far side./p

The voice came from the shadows. "Good. You're here." He placed a glass test tube onto the shelf in line with the others, and turned toward the doorway. He reached down a hand out to help her up into the room. When he leaned into the light, she could see his eyes were soft and shining, and he wore a calm, satisfied smile. Kitsu was familiar with this expression; it meant his experiments were going well./p

His hands were in the pockets of his white lab coat, and his eyes were not looking out the window, but, unexpectedly, seemed to be intently considering Kitsu./p

After being revived into this primitive world, she was just glad to be in a colony with people who built interesting things. At the rate their team was going with re-inventing all of human technology, she had hopes to see the beginnings of space travel in her lifetime./p

Scars crossed his forehead toward his eyes, like lightning bolts emphasizing his zealous energy. He held her gaze, still smiling. "Your work has been invaluable in this lab's progress. The iron forge, the improved telescope design... it was well done. And," he held up a braid of thin gold threads "when we build the generator, I'll be trusting you to make the most efficient use of our limited wire. ...But there's something essential missing from our scientific advances. Have you noticed," he continued, turning to look out the window at the moon rising over the empty village center, "This primitive village has been here thousands of years before we were revived, and still there are still only a handful of children. Hardly enough to keep humanity alive if there was one bad winter. The population needs to grow. Without people, there can be no science."/p

"Modern society depends on proper sexual fertility as much as on technology. I myself am eager to make children, but the village as a whole remains sparse because they carefully hold back. They have no reliable way to manage fertility. To enter the modern world, the village will need a way to have children, and also to em style="box-sizing: border-box;"not/em have children." There. The gauntlet was thrown down. Contraception: a pleasurable technology that their lab had not em style="box-sizing: border-box;"yet/em re-invented.

She feels a glow spread across all of her skin, and settle brightly between her thighs. Knowing that her nipples must be apparent through her dress, she turns toward him, hoping he notices. "Where shall we start? Extracting synthetic hormones from the Vitex berries and forming them into a monthly pill? Modifying the current rubber recipe to be stronger em style="box-sizing: border-box;"and/em thinner, to make latex condoms?" She let her dress fabric slide down her shoulder a little further, just in case. "Re-inventing such devices will change the purpose of sexual contact from em style="box-sizing: border-box;"pro/emcreation to em style="box-sizing: border-box;"re/emcreation.

A grin that expressed eagerness and anticipation, with eyes half closed and the corner of his mouth twisting up with delight. It was the same passionate smile as when he planned the first lightbulb. From his toolbelt, Senku retrieves a large, stoppered test tube and spins it between his fingers. He holds it up to the light. Inside is a transparent gel, almost pink in color./p

Senku smirked. He clearly enjoyed her shocked expression. He reached out with his free hand to embrace the small of her back and pull her closer. He pressed the vial into her hands, then reached to brush her hair away from her face. Leaning in close, he fervently whispered into her ear, "Get excited..."/p

Kitsu allowed herself to melt into him, becoming like molten steel, and feeling the sensation of his heartbeat. The warm and intimate rhythm of their breath mirrored the pace of the kiss, deepening and amplifying the intensity of the merging connection.

Her body was lithe and supple, and her skin still very soft from being revived out of stone. His eyes kept a burning contact with hers while his arms encircled her waist and shoulders to draw her close. While his fingers traced along her spine, he explained: "With this new recipe I developed, we can separate the em style="box-sizing: border-box;"social/em benefits of sex from the em style="box-sizing: border-box;"reproductive/em benefits. And so we can get the best of both."/p

Your brain is currently filling with dopamine, which anticipates pleasure." She pressed her hips toward his fingers, eager for them to reach her clit. "But soon that will shift into more serotonin and oxytocin...It's a complex cocktail of pleasurable neurotransmitters, all with personal and social benefits."/p

His tongue became acquainted with her thighs, lower belly, and outer labia before she felt his breath over her clit. Pausing, he breathed over her, "Just let me know if there's something I can do more optimally, ok? I'm taking mental notes on your unique needs." His tongue rounded the edges of her inner folds, allowing her clit time to yearn for it. Senku massaged and sucked at her with skillful precision and gentle adjustments, while Kitsu grasped the fur blankets and nearly sang out with pleasure./p

Kitsu managed to whisper through intermittent gasps. She smiled at him, though her face was tense and drops of sweat beaded on her temples. "That means from you, too, dear Senku." She reaches behind him and presses a finger against his backside. Reaching just inside, she penetrates him to press on a spot of maximum pleasure./p

She pulled him in deeper with her legs, until they collapsed together in a complete release./p

Senku chuckled and pulled soft fur blankets over them. "We'll need a lot of repeated trials... but with enough data points, we can assure the village that contraceptives work!" He wrapped his legs around her and she put an arm behind his head. They were feeling the joy of oxytocin neurotransmitters working to bond them as lab partners. "This oil will enable moderated fertility, a necessary building block in a stable, cooperative, and gender-equal scientific civilization."/p

This oil is much better. In numerous ways.'/p

A man able to hold the key accomplishments of all humanity in his mind, continually adapting the scientific principles of the universe in order to save all of humankind and make a valued place for em style="box-sizing: border-box;"every/embody in a new world. His tendrils of hair draped over his closed eyes, casting moonlight shadows across his cheekbones. Even in this relaxed half-asleep state, Senku still emanated a vital energy./p

She carefully carried a dozen rabbit pelts up to the round, thatched hut. With her arms full, she pushed the leather door aside and set the pelts on the floor just inside so she could push herself up into the room. Two beeswax candles made the room only slightly brighter than the almost-full-moon nightscape outside, but she could hear a clink of glass on the far side./p

His voice was bright and alive. "I've noticed we get along well. I'd like to ask if you..." Senku looks directly into her violet eyes, and pauses. Kitsu raises a brow, smiling. He's never at a loss for words, and finds it endearing for a split second./p

She feels a glow spread across all of her skin, and settle brightly between her thighs. Knowing that her nipples must be apparent through her dress, she turns toward him, hoping he notices. "Where shall we start? Extracting synthetic hormones from the Vitex berries and forming them into a monthly pill? Modifying the current rubber recipe to be stronger em style="box-sizing: border-box;"and/em thinner, to make latex condoms?" She let her dress fabric slide down her shoulder a little further, just in case. "Re-inventing such devices will change the purpose of sexual contact from em style="box-sizing: border-box;"pro/emcreation to em style="box-sizing: border-box;"re/emcreation.

A grin that expressed eagerness and anticipation, with eyes half closed and the corner of his mouth twisting up with delight. It was the same passionate smile as when he planned the first lightbulb. From his toolbelt, Senku retrieves a large, stoppered test tube and spins it between his fingers. He holds it up to the light. Inside is a transparent gel, almost pink in color./p

Senku smirked. He clearly enjoyed her shocked expression. He reached out with his free hand to embrace the small of her back and pull her closer. He pressed the vial into her hands, then reached to brush her hair away from her face. Leaning in close, he fervently whispered into her ear, "Get excited..."/p

Senku's breathing deepened to a slow and robust inhale, as if drawing her into him and savoring her scent. Kitsu allowed herself to melt into him, becoming like molten steel, and feeling the sensation of his heartbeat. The warm and intimate rhythm of their breath mirrored the pace of the kiss, deepening and amplifying the intensity of the merging connection. All of his substantial mind was fully present in that kiss, intertwining their emotions with the sensual experience. Yes, it was exciting. The experiment was already going well./p

She kneels beside him, opening his lab coat to reveal a slender but muscular torso. She wondered if he always wore nothing under the lab coat, or if it was only for tonight./p

"Here, I'll show you how it works..." He uncorks it and pours a generous amount of the liquid into his hands. Grasping the base of his shaft with one hand, he glides the oil gel lubricant over and around his hard cock. He dexterously massages it in, while Kitsu rests her hands on his thighs, watching with rapt attention. Did Senku somehow know that she liked to watch? Or is he really just that confident at all times?/p

Kitsu increased the speed of her hands slightly and Senku's voice falters momentarily, but not his thoughts. "And... I added a bit of clary sage too. For you." He lifted his eyelids just enough to make eye contact, and to see that she was impressed by his recipe. He also saw her sleeve had fallen off her shoulder, revealing subtle but alluring cleavage./p

His tongue rounded the edges of her inner folds, allowing her clit time to yearn for it.
