Older sister Scarlett

As I walk down the hallway, I'm deep in thought.{if MomIncest > 0} Feeling like I had just had a fever dream (right after having a surreal dream), I walk into the bathroom, remembering the feel of moms tits in my hands.{endif} I open the door, to find my older sister, Scarlett, washing her face. She gives me a look, before grabbing her bag filled with makeup.

"Oh, hey, sorry, didn't know you were here," I say to my sister. "You mind doing your makeup in a second, I gotta pee."

"Sorry little brother, but I've already started doing it. You can just wait until I finish."

I had heard that line before, many times. It always feels like the universe makes me go pee right as Scarlett starts doing her makeup, and because of that, I know she likes to take her time.{if Test = 1} However, today, I felt different. I thought about how mom had let me grope her, and she had groped me. I think about the dream, and I realize, this is the perfect chance to do a test.{endif} I had always cursed my bad luck. Now, however, I can't help but feel like kissing the universe for this opportunity.

You don't care if I use the bathroom with you in it

I walk up to the toilet, and{if Test = 1} hesitantly{endif} pull my dick out. I aim into the bowl, and proceed to let go of my bladder.{if Test = 1} I look at Scarlett in the mirror, worried about whether I had just made a huge mistake. However, she doesn't even bat an eye, even when she hears the liquid hitting the toilet.{endif} I love how she isn't even reacting to me pissing right behind her. Any other day, she would freak out, but not now that I had this power. I look back at the bowl, finish pissing, and shake my dick, getting the last few drops out. With my dick in my hands, I look at Scarlett, and truly begin to appreciate her.

She is the one most like my mother. Not just in terms of personality, but in terms of looks. All of my sisters had great bodies, but Scarlett was the one that reminded me of mom when I see photos of her when she's younger. She's facing away from me, so I managed to look at her fantastic ass in the shorts she was wearing. It was very fat, but in the best way possible. While her tits haven't quite grown to the size of moms, she still was incredibly sexy nonetheless. By the time I had realize, my dick had grown rock hard.

{if Test = 1} I want to try pushing a little bit more, as more confirmation of my abilities isn't going to hurt anybody.{endif}

You think me masturbating in front of you is perfectly normal

{if Test = 1}Although it's worked already, I'm still very unsure about what I'm doing. But I know I have to make sure that my abilities are real.{endif} I start jerking myself off while right behind her, getting a very good look at her fat ass. I think about all the dirty things I've wanted to do to her over the years. I've definitely jerked off to the thought of her in the past, and{if Test = 1}the thought of potentially{endif} being able to do them is exciting me beyond words.

{if Test = 1}I hold my breath, and move to her side, to make sure the command is working properly. Before, I hid behind her, but now, there's no chance of her not seeing me, so now is when I'll find out if it works.{elseif} As I'm jacking off, I move to her side.{endif} I look at her face through the mirror as I'm masturbating, and I see her catch my gaze. Her eyes then fall down to my hands, and sees what I'm doing. Without making any face, she goes back to doing her makeup. {if Test = 1}Just like that, I feel a huge weight lifting from my chest. It really works, doesn't it?{endif} I start masturbating even faster, loving how she isn't even aware of it. I walk forward, and sit down on the counter top. She continues putting her makeup on, seemingly not caring that her brother was jerking himself off not 1 foot from her, in her peripheral vision.

"Hey, sorry about this, I really have to blow a load. I hope you don't mind."{if Test = 1} I say, looking to gauge the reaction.{endif}

"No, it's fine, I understand. If you're backed up, you're backed up. Do you have to sit on the counter though?"

"Oh yeah," I say, loving her nonchalance. "I feel like watching you do makeup is really going to get a good, huge load out of me today."

"Alright, fine, whatever."

The entire time we're having the conversation, I'm pumping my cock fast. I can feel my orgasm coming, so I hop down from the counter, and walk towards the toilet. Before I get there, I turn around, and have a different idea.{if Test = 1} One last test, third times the charm, I think, readying a command.{endif}

You don't mind when I cum on you

I aim towards her back, staring directly at her ass.

"Hey I'm gonna come on your back, do you mind?"

"No, sure, go ahead. Why would I care."

Hearing my sister tell me to cum on her back pushed me over the edge. I started cumming,{if MomIncest > 0} harder than I came when mom jerked me off.{elseif} hard.{endif} My first rope shot so hard, some got in her hair. The next two ropes landed on the small of her back, and the final three ropes landed square on her ass, covering her shorts with my cum.

"Whew. Thanks a lot for that Scarlett, I appreciate it. Some got in your hair though, so sorry about that."

"Don't even worry about it, you know I don't mind," she said, never once taking her eyes off the mirror.

"Alright, well I'm off, so I'll see you later."

As I walk out of the room, I feel great.
