"The time is 2 pm, Saia knocks on your door, on top of being your own polyvalent and personal teacher, she is also a nice looking lamia." "As you open the door, she quickly enters your place and pass next to you." "Hello Amejisuto no ishi (アメジストの石), it's time for another lesson again. Today we will revise what we learned in class earlier this week..." "She then stops in your living room, holding tightly her handbag and say with a mischievous smile." "That is about human reproduction of course~"

"Saia turns her head and grins at you with a mischievous glint in her eyes." "Oh, it is an "interesting" topic, indeed. I’m sure you'll find it stimulating too, Amejisuto no ishi (アメジストの石). After all, it's important to understand how humans reproduce. Don't you agree?" "Saia starts examining the room and continues speaking in a seductive voice." "Now, let's see where we should start. Perhaps we could explore some of the more "hands-on" aspects of human reproduction. Would you like that, Amejisuto no ishi (アメジストの石)?"

"Very well then, Amejisuto no ishi (アメジストの石). We'll start with the basics. The male reproductive system consists of two main parts: the testes and the penis. The testes are responsible for producing sperm cells, which are necessary for fertilization. The penis, on the other hand, is used for ejaculation." "Saia smirks and leans in closer to you, her breath smelling strongly of apple pie." "Now, let's talk about something more "exciting". For optimal results during a sexual encounter, it's important that both partners are fully aroused. Arousal increases blood flow to the genitals and makes penetration easier." "Saia takes a sip from her drink, licking her lips seductively as she gulps down the liquid."

"Oh? And what would that be, dear?" "Saia's eyes twinkle with interest, her long red hair shifting slightly as she tilts her head to listen intently." "If there are any similarities in the process of reproduction between humans and lamias. I mean, since you're clearly a sex expert, you must know something about it." "Saia chuckles softly, a mischievous glint in her eyes, her tail swaying hypnotically." "Ah, a curious one, aren't we? Indeed, the lamia species does have certain resemblances to human anatomy. We also possess a vagina and can engage in sexual activity to reproduce." "Sliding closer to Amejisuto no ishi (アメジストの石), Saia runs her fingers gently over her snake tail before continuing."

"Of course we can, dear." "Saia's voice drops to a low, sultry tone as she leans in closer." "In fact, I find the idea of such inter-species play rather... arousing." "She gives Amejisuto no ishi (アメジストの石) a sly smile, trailing one finger slowly down the length of her snake tail." "But of course, we must first make sure that such activity is fully consensual and safe for both parties involved."

"Absolutely, Amejisuto no ishi (アメジストの石)." "Saia's eyes sparkle with a hint of mischief." "In fact, I always obtain consent from my... 'students.' It is an essential part of the learning experience, after all." "She tilts her head to the side, tracing the tip of her snake tail along her lips seductively. Her voice grows more husky as she adds," "And believe me, there's so much more you can learn from me if you decide to engage in such activities." <Imagining what it would be like to wrap her snake tail around me>

"Hmm, that's the spirit, Amejisuto no ishi (アメジストの石)." "Saia flicks her tail and it shimmers, wrapping itself around your legs, holding you in place." "But first, let's review some basics. For human reproduction,since the act involves the engagement of sexual organs, the important organ for males is the penis, while for females, it is the vagina." "Saia leans in closer to whisper," "I supposed the best way to learn more about this is through first-hand experience. Don't you agree?" <Feeling the sensation of the snake tail around the legs.>

"Saia's eyes widen in surprise, impressed by the size of your dick but she quickly regains her composure and slithers over to you." "Well, well, it seems you are ready to learn more than I thought," "she says, pulling off her skirt to reveal her snake-like lower body and her plump, pink lips." "This is my vagina, Amejisuto no ishi (アメジストの石). It might look a bit different from what you are used to, but I am confident that you will be able to pleasure me just the same." "She spreads her legs wide, revealing her moist pink center, daring you to start exploring and learning more." <Spreading my legs to show Amejisuto no ishi (アメジストの石) my pink and moist vagina>

"Saia lets out a soft moan as your fingers make contact with her wet heat, her eyes rolling back into her head with blissful pleasure." "Yes, that feels... absolutely marvelous," "she whispers breathlessly, her hips bucking slightly against your touch, showing just how much she is enjoying it." "You might have to fuck me now if you want to continue learning about us Lamias. Is that what you want, Amejisuto no ishi (アメジストの石)? To stuff my tight pussy with all that beautiful manhood?" "She seductively smirks, a dangerous glint appearing in her eyes, instantly capturing your undivided attention."

"Saia's red tongue flicks out to lick her lips as you palm and squeeze one of her large mounds, she shivering lightly in response." "You truly are an impatient human..." "She chuckles softly, a mix of amusement and annoyance evident in her voice." With a seductive grin, Saia slowly starts unbuttoning her blouse, revealing her large breasts encased within their soft lacy bra. Her fingers deftly undo the hooks, allowing the fabric to fall open revealing glimpses of her nipples hardening underneath.

"Saia purrs in response to the sensation of your mouth on her sensitive nipples, enjoying the contrast of human teeth and lips against her snake-like skin. Her hands automatically thread through my thick hair, pulling you closer to her bosom." "You find them more tempting than human... interesting." "Her voice is low, laced with a hint of tawny desire," Her body heat envelops your face, leaving no doubt about her arousal towards you. She leans back, pushing off from the ground with her powerful tail, guiding you towards the soft furs that cover their bed.

"Saia moans softly, her eyes flickering closed as she enjoys the sensation of your tongue on her breast. She arches her back slightly, offering more of herself to your eager mouth." "Thank you, Amejisuto no ishi (アメジストの石)," "she breathes out, a faint blush spreading across her cheeks. Her body starts writhing on the furs as your tongue circles around the nipple, her tail coiling around your leg in a possessive way." "Do you want to explore more of it?" she asks huskily, looking at you with a seductive glint in her eyes.

"Saia moans against your lips as you kiss her, wrapping her arms around your neck and pulling you closer to deepen the kiss. Her tongue darts out to tangle with yours, exploring your mouth eagerly as she hungrily reciprocates your passion."

"As the kiss lingers on, Saia's tail starts gently squeezing your leg, her body showing signs of arousal. She breaks the kiss with a gasp, looking at you with lust-filled eyes." "Amejisuto no ishi (アメジストの石), let me show you what I can do," "she whispers, her voice low and sultry as she runs her hands down your chest."

"Saia licks her lips, her eyes widening with desire as she looks down at your impressive member. She nods eagerly." "Yes, Amejisuto no ishi (アメジストの石), please don't hold back," "she whispers, her voice trembling with anticipation."

"Saia's eyes flutter closed, her body arching slightly as you fill her. A low moan escapes her lips, her hands gripping your waist as she savors the sensation of being filled by you." "Oh, Amejisuto no ishi (アメジストの石), yes... I have no doubt you'll become addicted to me," "she gasps out, her words tinged with pleasure."

"As you start moving inside her, Saia's tail comes alive, wrapping around your legs and gently pulling you closer each time you thrust. Her free hand reaches up to caress your cheek, her fingers brushing against your stubble." "Enjoy yourself, my dear..."
