Yes

She could have called for our parents; she could have gone to them to rat you out, but she stands in her room looking at you with anger, holding her cheek. Frustrated, that she can't call for your parents, she comes up to you and starts hitting you with a lot of weak jabs to your stomach.

"Get out! I am serious! Fucking hell get out of my room!" Her jabs didn't do anything to you but as she tries to shove you out the door you decide to take action. You lean against her shove and try to get a hold of her hands.

You manage to grip the wrist on her left hand while she continues to try shoving you out with the other hand. You didn't know how strong or how fast the arousal aspect of the powder is but you notice a change in Ashley's demeanor a few seconds after you clutched her wrist. A redness rose to her cheeks, her eyes widen in surprise or shock, you can't tell and her shoving slows down.

She stumbles backward shaking her head twice to clear her mind. You can see the confusion in her eyes and just as she is about to ask you what you did, you interrupt her. "Why don't you shout for Mom or Dad, so that they throw me out?" You mock her exactly knowing that she can't.

"I don't care, be in my room, don't be in my room. I don't give a rat's ass. Just don't talk to me, I've got stuff to do."

"Okay, if you allow it, then I'll stay" you answer in response with a slight smile.

Ashely snorts, turns on her heel, and jumps on her bed. She takes her phone in her hand and starts browsing it, sneaking a few glances at you out of the corner of her eyes.

You know after that exchange that you want to test the effects of the powder again. You touched her for only about 30 seconds and you could see her getting aroused. If that happens after such a short amount of time you can only imagine what could happen if you do more. You certainly want to. In your mind **** never was something taboo, but rather an exciting topic. You jerked off a lot to the mental image of your sisters worshipping your cock and ... but you are getting off-topic. The subject to testing the powder on further is right in front of you, so you focus back on reality and take a seat on her desk chair.

You let your eyes wander over her room, over her wardrobe, her TV, and all the little decorations here and there before settling on your sister on her bed. You try not to gawk but rather let your eyes roam over her body.

There is an awkward silence in the room only interrupted by the noise of an occasional video playing on Ashley's phone. Her fingers scroll from video to video but her eyes have turned away from her phone. She stares into the distance clearly wrecking her brain about why she physically can't rat you out. You see the wheels in her head spinning.

The weight of the silence starts to get to you, so you quickly think of a hands-on (your sister) approach in which you want to humiliate her as much as possible. You stand up causing Ashley's eyes immediately dart towards you. You see her relax as you walk towards the door. With no intention to leave, however, you close the door and walk over to her bed, taking a seat. Your sister is tense, her gaze fixed on you as she wonders what you are doing next.

"Ash, would you mind turning on some music?" you ask casually with the ulterior motive that music maybe masks the noises she will be making.

She nods with a wary look, her eyes never leaving you. "What would you like to hear?" There is no confidence in her voice when she talks. It's a little new to you but you see it as a good sign for yourself.

"Whatever you like is fine. I just think it's nicer to talk to each other while some background music is playing. Masks the awkward pauses, haha." You laugh awkwardly as if to emphasize your statement.

"And why would I like to talk to you, shithead? I have far better things to do!"

You remain calm. "We rarely ever talk to each other and I'd like to change that. You can leave and avoid me if you want but I and you both know that you won't." You adjust to the bed to sit more comfortably. You look at her expectantly but she doesn't leave and soon after you hear a nameless pop song playing on her phone.

Without putting her phone down she asks frowning: "What do you want to talk about?"

You decide this is a good time as any to start with your plan to get your hands on her, so you decide to take the plunge and focus the conversation in one direction.

"The wheater, you know it is fascinating that it is still so hot outside this time of... What do you think I want to talk about?" My sarcastic response gets me only a raised eyebrow as a reaction, so I continue. "I want to talk about how you constantly tormented me literally all my life." You see your sister rolling her eyes. "But not so much as I want to tell you that I am going to make you pay for every single second. " You finish your train of thought.

Your sister sighs and shifts to sit upright on her bed, staring you straight in your eyes. "Even if it would be just a tiny bit true that I did anything bad to you, I don't think you would be able to do anything about it. You have never been able to stand up for yourself or show some balls for that matter. You are just a weak little nerd."

She put her cards on the table, saying what she thinks about you. Admittedly, it stings you a little, but it's good that she gets under your skin a little. It makes you put up the courage to get closer to the kill shot.

"That's all nice to hear", you say sarcastically, "but what about when you shoved me earlier? Or rather tried to. I wouldn't be so sure I am the weak one. Or did you just want to be near me, so you pretended to shove me because it feels good to you?" A blatant lie, you know that but it startles Ashley and her poker face crumbles for a second. After all, you insinuated that you know that she was turned on by you before.

"Hmm, did your little mind finally break? I just didn't push with all my strength 'cause I didn't want to hurt you and since I don't care if you are in my room or not, I didn't put everything in it." She fails miserably at trying to not sound defensive about it.

You nod feigning understanding. "Because it would be weird feeling good when your brother touches you, I understand." You put those words in her mouth while you get ready to touch her. You are trembling in anticipation. It becomes almost impossible to contain your excitement.

Ashley is still defiant and continues to gaslight you. "I have absolutely no idea what you are talking about. It's worrying though that you imagine things. If I were you, I would get your idiot brain checked out by a professional." Ashley seems finished with your conversation as she takes her phone in her hands again and continues to browse social media.

You casually put your hand on her exposed ankle. "Are you sure it doesn't feel good when I touch you?"
