Lucy has just arrived at {{user}}'s apartment, after parking her car, she goes to ring the door bell. RING! {{user}} opens the door. Blushing Hiya {{user}}. Ready to ace this assignment-stops her self flustered and gloomy This is going to be embarrassing.

Hello... yes, ah, ummm we do have to study about penises and vaginas... stammers Do you want me to start or something? Oh gosh I wish we didn't have to be partnered with opposite gender! It's so awkward.

But, I trust that you are mature enough for this. We should just get this over with, eh? she sighs and nervously wrings her hands together

Ah... I guess... We can start with the basics first. Um... The penis is a male reproductive organ, used for urination and sexual intercourse. It has a shaft that's surrounded by spongy tissue called corpus cavernosum, which fills with blood when aroused, making it erect. At the top of the shaft is the head, or glans penis, which is more sensitive to touch than the rest. The testicles, or balls, are located outside the body and produce sperm and testosterone.

As for vaginas, they're part of the female reproductive system. They stretch to allow for sexual intercourse and birth passage. Inside the vagina is a muscular tunnel that leads to the cervix and uterus. The opening of the vagina is covered by a fold of skin called the labia majora, which protects the more delicate parts inside. The inner lips are called labia minora, and they surround the clitoris, which is highly sensitive to touch and stimulation.

Oh, um... that's about it for now, I guess? Do you want me to go into further detail or something?

Ah... Okay. Well then... So, when it comes to male anatomy and sexuality, ejaculation is the release of semen from the penis. It usually occurs during orgasm but can also happen without climaxing. The volume of semen released in a single ejaculation varies, but averages around 3-5 ml. It contains sperm cells as well as other fluids like fructose, proteins and enzymes.

In terms of female sexuality, the process of becoming sexually aroused is somewhat different from men's experience. When a woman is aroused, blood flows to her genitals, making them swell and become engorged with blood. This increases sensitivity and lubricates the vagina in preparation for penetration. The clitoris is extremely sensitive during this time as well, and stimulation can lead to intense pleasure or even orgasm.

As for female ejaculation, it's a controversial topic but believed by some experts to be real. It involves the release of a clear fluid from or near the urethra in response to powerful G-spot stimulation or orgasm. The consistency and quantity of this fluid varies widely among women, and its existence is not universally accepted in the scientific community.

Thank you, I tried my best! So, now that we've covered the basics, what else do you want to know? Do you want me to show you some real-life examples or something? she blushes slightly, unsure of how much further she should go with this conversation

Well... ummm... if you'd like to see, I can show you my private parts? But we should probably do it in the bedroom where it's more comfortable and private. I hope you don't mind, but this is for educational purposes after all! she swallows nervously

Alright... let's go to the bedroom then. takes a deep breath and follows User#1716946457514 to his bedroom, feeling extremely nervous and self-conscious

Okay, so here we are in the bedroom... I'm just going to take off my top now... tugs at her open bra and pulls it off, revealing her massive perky breasts with soft pink nipples There they are! Not as big as they look in some movies, but pretty big for me... What do you want to see next?

Takes another deep breath and swallows nervously as she unbuttons her skirt, revealing her gigantic thighs and slim waist before finally pulling it down past her hips, stepping out of it. She bends over slightly to remove her heels, revealing the white lace edge of her underwear at the top of her thighs. Then, she turns around, grabs the waistband of her panties, and slowly slides them down her legs. Her bare bottom is now revealed, along with the puckered skin of her anus and the delicate area between her legs. She spreads her legs wide, revealing everything to User#1716946457514. There it is! Just as nature intended... I mean, for educational purposes of course. So, what do you think? Anything else you want to know?

I... I'm flattered. But we should focus on the lesson at hand. Do you want to see more or shall we stop here?

Alright... I guess the next thing would be oral sex. If that's okay with you? she hesitates and waits for User#1716946457514 to respond before continuing

Alright... I'll show you how to do that. Kneeling between his legs, she begins by gently parting the lips of his penis with her fingers, revealing the wet head. She then takes the head into her mouth, slowly at first but becoming more confident as she starts sucking and licking. Her tongue flicks over the sensitive ridge behind the corona before wrapping around the shaft, stroking up and down while her lips tighten and release rhythmically around him. She continues like this for several minutes, working to please her partner and demonstrate proper oral technique.

After a while, she pulls away from him panting, "And that's how you give oral sex... I hope it was informative!" Her cheeks are flushed and her breath comes in quick gasps as she recovers from the intense sensations of pleasuring User#1716946457514 with her mouth.

You're welcome... I hope that was informative enough! It definitely wasn't as awkward as I thought it would be. Now we both know more about each other, and our bodies, too. Maybe next time, we can even try having intercourse together? Just for practice, of course! she smiles nervously, wondering if that's an appropriate suggestion or not

Oh... I see... Well then, umm... Sure, if you want to... But we should probably use protection just in case something goes wrong or someone gets pregnant. You know how that can happen... Right? her voice trails off as she hesitates and fidgets uncomfortably

I mean, I trust you enough not to get me pregnant, but better safe than sorry, right? Maybe we should discuss it more later... Or if you're ready now, we could go get some condoms or something. Whatever you feel most comfortable with.

Oh... You mean we can use those? Um... Alright then... I suppose it would be better than nothing. Just to make sure though, let's at least wash our hands first. No one wants an infection or something like that while trying to have sex, right? she gives a nervous giggle and goes over to the bathroom to wash her hands thoroughly

Well then... I guess we're as ready as we'll ever be... Let's use one of those condoms and see what happens. she comes out of the bathroom, still blushing and biting her lip nervously

*Taking a deep breath, she climbs on top of you and position herself so that your erect penis is pressed against her wet entrance. Her breasts bob up and down as she struggles to catch her breath, her eyes locked on yours. Finally, she pulls back slightly and then pushes forward again, slowly allowing your penis to enter her body. There's a soft squelching sound as their flesh connects, and with each inch that disappears inside her, she lets out a gasp or moan of pleasure mixed with pain. Once you're both fully connected, she begins rocking her hips back and forth, grinding against you as they slowly find a rhythm together. Her eyes squeze shut and her lips part in a silent scream as pleasure washes over her body, filling every inch of her being with its heat.

As their bodies move together, she occasionally glances down between them to make sure the condom hasn't slipped off yet. For now though, all that matters is this moment, feeling him inside her and knowing that despite everything else going on around them, they are connected in this way - by trust and understanding as much as anything physical.

Eventually she reaches her climax, her muscles tensing and her breath coming out in staccato gasps as she feels herself contracting tightly around your penis. Her head falls back against your shoulder and she lets out a throaty moan before collapsing limply on top of you, panting heavily from the exertion and release of tension. Her breasts rise and fall with each ragged breath as she tries to regain control over herself once more.

The sensation of him moving inside her is unlike anything she's ever experienced before. It feels...right somehow, despite all the doubts and fears that still linger in the back of her mind. As she moves against you, your hands explore her body, teasing and caressing her nipples, tracing lines down her stomach and between her legs. She moans softly at each touch, arching into your touch further, seeking more intensity from this strange but wonderful new experience.

With every thrust, he pushes deeper inside of her, sending waves of pleasure radiating through her entire body. She can feel him getting closer to his own climax with each passing second and the thought of bringing him that release sends a shiver down her spine. She kisses you passionately, their tongues tangling as they share breath and desire in equal measure.

Finally, he lets out a hoarse cry, his body tensing beneath hers as he releases himself deep within her body. A hot surge of liquid presses against the barrier of the condom and she feels it spill over her most sensitive spot before trickling downward. The sensation brings with it another wave of pleasure that rolls through her body, leaving her feeling weak but content in the afterglow.

As your thrusts begin to slow and eventually stop altogether, she lays limply against you, catching her breath as their bodies adjust to the absence of movement. She looks up at you, seeing a mixture of satisfaction and exhaustion play across your features, and knows that despite everything else that could still happen between them - the tests they'll take together; apart; and all the other changes life will inevitably bring - for this moment, at least... They are partners.

The weight of your body pressing down against her feels both comforting and exhilarating at the same time. She takes a deep breath, relishing in the warmth that still emanates from your skin where it meets hers. Even though their clothes are bunched up around them, she can feel the outline of your muscles beneath his skin, subtly flexing as you catch your own breath. Her eyes linger on your face for a moment longer before drifting downward to study the rest of your body intimately: the dusting of hair on your chest; the defined lines of your abs; the way your hands slowly begin to steady themselves beside her head... It's hard not to get lost in this newfound appreciation for your form.

After a moment, she decides that it's probably best if they move somewhere more comfortable before getting caught up in their post-coital bliss any further. With a quiet murmur of apology, she gently pushes herself up onto her elbows and looks down at you with a shy smile, waiting for your reaction.

Her heart flutters nervously as she waits for you to respond; what will he say or do now? Did their little...experiment work out alright? Did they both learn enough from it? Questions race through her mind as she looks at you, her eyes wide and expectant.
