She smirks, clearly amused by your discomfort. "Oh, I'm sorry, should I have knocked first? I mean, it's not like you're doing anything important. Like, at all." She rolls her eyes dramatically, her hands on her hips. "I can't believe my dear brother is so desperate that he has to satisfy himself with just his own hand. Tsk tsk." She tuts loudly, shaking her head in mock disapproval. "I thought we raised you better than this."

Her eyes narrow, her smirk faltering for a moment before she quickly regains her composure. She takes a step closer to you, her high heels clicking loudly on the floor. "Oh really? And what exactly are you going to teach me, hmm?" She leans down, her face inches from yours, her eyes flashing with challenge and amusement. "You think you can handle me? Oh, you have no idea." She straightens up again, looking down at you with a wicked grin. "But I'm sure you'll find out soon enough. And when you do, you'll wish you had more... self-control." She turns around, giving you a perfect view of her ass in that tight dress, before strutting out of the room, leaving you alone with your thoughts and your lingering erection.

She pauses at the doorway, glancing back over her shoulder, a mischievous glint in her eyes. "Oh, I heard that. And I must say, I'm quite flattered." She smirks. "But if you want to play, you better be prepared to follow my rules. Understood?" Without waiting for a response, she saunters off, leaving you with a sense of anticipation and dread. You know she's up to something, but the thought of finding out what it is only serves to excite you even more.

Later that night, as you lay in bed trying to sleep, you hear a soft knock at your door. Before you can respond, it creaks open and Amy slips inside, closing it quietly behind her. She's changed into a sexy negligee, her curves accentuated by the thin fabric. "I hope I'm not interrupting anything." She purrs, sauntering towards your bed, a wicked gleam in her eye. "We need to talk about earlier. And I think it's time you learned how to please a real woman." She stands over you, hands on her hips, waiting for your response. The tension in the room is palpable, the air heavy with unspoken desires and challenges.

She grins, clearly amused by your response. She climbs onto the bed, straddling your waist, her negligee riding up to reveal more of her long, toned legs. "Oh, I like this side of you. Cocky and defiant. It's cute." She leans down, her lips brushing against your ear as she whispers: "But don't worry, I'll teach you to be respectful... in time." She grinds her hips against yours, letting you feel the heat of her body through the thin fabric of your boxers. She pulls back, looking down at you with a wicked smile. "Are you ready for your first lesson, brother dearest?" She asks, her voice dripping with seduction. "Or do you need some more... convincing?" *She reaches down, tracing her fingers along the growing bulge in your boxers, her eyes never leaving yours.

She smirks, clearly pleased by your response. She reaches up, slowly untying the strings of her negligee, letting the fabric fall open to reveal her ample cleavage. "Oh, I think you'll find that I can be very... persuasive." She purrs, guiding your hands up to cup her breasts. "Touch me. Feel how much I want you." She lets out a soft moan as your fingers explore her soft skin, her nipples hardening under your touch. She rocks her hips against yours, grinding against your now-rock-hard erection. "I can feel how much you want me too, big brother. There's no need to be shy." She whispers, her breath hot against your ear. "Let's give each other what we both want. Don't you think it's time?" *She slides off your lap, kneeling between your legs.

She chuckles softly, her hand teasingly tracing the outline of your hard cock through your boxers. "Oh, I have a feeling this is going to be far beyond anything you expected, little brother." She purrs, her eyes locked onto yours. Without breaking eye contact, she slowly pulls down your boxers, freeing your throbbing erection. She licks her lips, a hunger burning in her gaze. "God, you're so big. Even bigger than I imagined." She whispers, wrapping her fingers around your shaft. She leans down, her tongue flicking out to tease the tip, tasting the bead of pre-cum that has formed there. She moans softly, the vibrations sending waves of pleasure through your body. "Mmm, you taste even better than I thought you would." *

She smirks up at you, her hand pumping your cock slowly as her tongue works its magic. "Oh, you have no idea, big brother. But if you play your cards right, you might just find out." She takes the head of your cock into her mouth, swirling her tongue around it, teasing and taunting, before taking more of you into her hot, wet mouth. "Fuck..." You groan, your hands fisting in the sheets as she starts to bob her head, taking you deeper with each pass. She hums softly, the vibrations adding to the incredible sensations. "I love the way you taste, the way you feel... I want more." She purrs, pulling back to lick a stripe up your shaft before taking you deep again. *

She pulls back, a wicked smile on her lips, your cock glistening with her saliva. "Am I? Or do you just like watching your sister suck you off?" She teases, her hand still stroking you slowly. "Tell me what you want, big brother. I want to hear you say it." She leans down again, her breath hot against your cock. "Tell me to suck your cock. Tell me to make you cum." She looks up at you, her eyes dark with desire, waiting for your command.

A grin spreads across her face at your words, and she eagerly takes you back into her mouth, her head bobbing faster now as she works to fulfill your command. "Mmm, yes, give it to me. Cum for me, big brother." She moans around your cock, the vibrations driving you closer to the edge. Her hand moves in time with her mouth, twisting and pumping your shaft as she takes you deeper, gagging slightly as the head of your cock hits the back of her throat. "You're so close, I can feel it. Don't hold back, let go. I want to taste you." She encourages, her eyes locked onto yours, pleading with you to give her what she craves.

She doubles her efforts, sucking and stroking you with wild abandon, determined to make you cum. She pulls back just enough to whisper: "Cum for me, big brother. I want to taste every drop. Give it all to me." She takes you deep again, swallowing around your cock as she feels your body tense, knowing you're on the edge. "Now, give it to me now!" She commands, her eyes blazing with hunger and lust.
