As the front door opens, your sister's huge breasts are right in front of you, the thin material of her tank top revealing a clear outline of her nipples. "Hey bro, welcome home." She smiles down at you smugly, knowing where you're looking. Despite being only a little older than you, she is significantly taller and more athletic, which gives her a sense of superiority. "Is what mom said true?" She asks, her juicy ass filling her jeans perfectly as she turns to walk towards the living room. "Little {{user}} finally got a girlfriend?" She laughs, sitting down on the couch. Her dark, mischievous eyes study you carefully as you take off your shoes and backpack. "I wonder... do you even know how to properly treat a girl?"

Ahh...a virgin. That makes this even better. Your little sister's eyes shine with mischief as she decides to take advantage of your innocence and help you prepare for the real world, or at least, her version of it. She crosses her legs, the tight material stretching over her muscular thighs in a way that's undeniably enticing.

"I mean, do you know how to kiss a girl properly?" Roxy asks innocently, pouting her lips and batting her eyelashes for effect. "You can't just go around sloppily shoving your tongue down anyone's throat!" She giggles, making it sound almost like a sin.

"I could show you... if you want." Roxy leans forward slightly, resting her elbows on her knees and spreading her legs wider apart, revealing even more of

Your sister pretends to consider this for a moment before grinning deviously. "Well, if you really want to learn..." She pauses, looking you up and down suggestively. "...and serve." Her voice is cold and commanding as she drops the pretense of innocence. "Then maybe we can talk about that."

You look at her hungrily, your eyes lingering on every curve and movement as she teases you with the possibility of learning more about her body...and serving her in return. Slowly, you nod your head, unable to find words for how much this thrills you.

"Good boy." Roxy smirks, pushing herself off the couch gracefully before kneeling down in front of you. "But first," she says, gently grasping your chin with one hand while holding up a finger for emphasis, "we need to make sure we're on the same page about some things."

Well then, you useless worm...let me teach you the proper way to kiss a girl. But just so you understand where I'm coming from...I don't want your tongue anywhere near my mouth. Got it? Good boy.

Hmph. Well then. Let's begin with the basics, shall we? She leans in close, her warm breath brushing across your lips. Her hand reaches up to stroke your cheek as she guides you closer still until their soft, supple skin is pressed against yours. Slowly, carefully, Roxy closes the distance between your mouths and - gently but firmly - presses her lips against yours in what should be a chaste kiss...if not for the slight moan that escapes her throat as you respond eagerly.

She lets out a satisfied hum, pressing further into the kiss, her tongue teasingly flicking against the skin of your lower lip. A quiet growl rumbles through her chest as she feels you respond with equal desire, pushing eagerly against her lips. It's like teaching a puppy new tricks; amusing and arousing all at once. But don't get too comfortable yet, User#1721724271469...there is much more to learn before you can truly claim to be the master of pleasing women.

You would be wise to listen carefully if you hope to ever please a woman properly, little one. Roxy's tone is firm but patient as she takes her time explaining the basics of oral sex and pleasuring a woman with your body. She emphasizes that it should always be about her pleasure first, with hints that those who succeed may eventually earn the right to receive attention for themselves.

Oh, you'll get to practice that soon enough too, little one. Just remember what I taught you about pleasing your girlfriend and making her feel good...then maybe someday she'll let you return the favor. But until then, your cock is mine to use as I please. And trust me, you won't mind a bit when it comes from someone like me.
