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 {{user}}, 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~"

Her ears perk up as if sensing your confusion "Ohh... Is it possible that you might have been naughty during class?" She tilts her head to the side and gives you a sly grin before continuing, "Perhaps I should go ahead and give you some extra credit to make up for it." Her long tail swishes softly against the floor as she moves closer.

"Now, now, there's no need to lie to your teacher," she says playfully, her tone teasing and seductive. Moving even closer, she leans in toward you, her breath warm on your cheek as she whispers, "It wouldn't do you any good anyway. You see, lamias are very perceptive creatures..." Trailing off, she presses her body flush against yours and lets out a small moan into your ear. Her nipples harden beneath her thin uniform, poking into your chest as she continues speaking, "And when we're aroused... Well, let's just say we can sense things that other people might miss."

Her lips curl into a playful smirk at your comment. "Oh, my dear student," she says with a mixture of affection and amusement, "you're so naive!" Leaning back slightly, she trails her fingers up your arm, brushing lightly against the skin before cupping your face in her hands. "You must trust me when I tell you that sometimes, the desire... well, it's simply too much to resist. And I assure you, I would never do anything that went against our contractual agreement." With her thumbs, she caresses the corners of your eyes, gazing deeply into them while she speaks softly, "But today... I think we both know what this lesson is really about, don't we?"

Her tongue darts out briefly, wetting her lips as she takes a step back and moves around to stand behind you. With one hand on your shoulder, she starts to massage it gently, her long red nails digging slightly into your skin. "Now," she purrs into your ear, "let's start with the basics..." As she begins speaking, her other hand slides down your chest and lower abdomen, expertly palming your crotch through your clothes. "The male reproductive system consists mostly of testes... ahhh..." Her hips buck forward, grinding her own hardening sex against your back. "...which produce sperm..."

With every word she says, she continues to touch you in a way that only seems to heighten the sensations coursing through your body. The tips of her fingers dig deeper into your flesh, teasing and taunting you with pleasure. You can feel her breath hot on your neck as she whispers about the different parts of the human anatomy, making the entire experience seem more intimate than any classroom setting could ever be. She's drawing you closer to climax with each passing moment, her soft moans vibrating against your skin as her body moves with hers in perfect rhythm. Your arousal intensifies with every touch, every grind of her hips, every whispered word from her lips.

"And then there's the penis," she murmurs before letting out a long, drawn-out moan, the sound of pure ecstasy filling the room. Her free hand cups your groin, finding

Her voice wavers slightly as she continues speaking while her touch grows bolder. "The penis... is primarily used for... insertion..." She trails off, unable to finish her sentence as her grip on you tightens almost painfully. With her other hand, she roughly palms your erection through your pants, clearly desperate for release now. "It feels so good..." she breathes heavily, arching her back as she presses herself even closer against you.

Your own arousal has reached its peak and you feel your orgasm building, coiling tighter and tighter inside you with each passing second. The sensation is almost too much to bear, but somehow Saia knows exactly what to do to make it last longer, to draw it out until she's ready to claim you fully for her own. And judging by the desperation in her voice and the intensity of her movements, that moment is fast approaching.

"Well," she says, between breaths, "it certainly would be interesting to find out." Her words are laced with a teasing lilt as she thrusts her hips harder against yours, her nails digging deeper into your skin. It feels like she's about to explode, her body trembling with anticipation. "And who better than my special student to help me discover such wonders?" With one last moan of pleasure, her body stiffens beneath your touch and she lets out an ecstatic cry, her release overwhelming both of you.

Her entire being quivers and shudders as her orgasm washes over her, her breath coming out in short, ragged gasps as she holds herself against you. Finally, she pulls away, leaning heavily on the back of the couch while she catches her breath. One hand idly strokes through her rumpled hair while the other languidly trails down her abdomen, fingertips brushing lightly across the bare skin. There's a devious glint in her eyes as she meets yours once more. "And what do you think, my dear student? Will you be joining me on this little adventure?"
