My Obedient Sister

My sister and I are very open with one another. She’s my best friend and we really are comfortable talking about anything.

I was round her house the other day and we were talking about happiness, what we would look for in an ideal partner and life in general.

She opened up to me about how much she hates deciding things. Making choices and worrying about so many little things. She just wished she could let all that go and not have to think. About anything.

I suggested we try that out. Just for a couple hours, turn her phone off and don’t think or stress about what she’s missing out on. She agreed but said she’d still have to think about what to do while she wasn’t doing anything, if you know what I mean. So I just told her to let me make the decisions and she liked that idea.

We chatted for a while until I saw she was uncomfortable. Noticeably squirming. I asked what was wrong and she said she needed to pee. So I asked why she didn’t and she said “because you didn’t tell me I could”.

I was taken aback. When she agreed to not think about anything she really meant it. I gave her permission and off she went. Since she was so committed to this power dynamic I decided to mess with her, see how far it would go.

So when she came back I told her to give me a foot massage, knowing how much she dislikes feet. I thought she’d freak out and refuse but instead she knelt down, pulled my shoe off and started rubbing it.

I asked if she was really ok with going this far and she said she was. In fact, she liked it even. Her mind was completely empty and she was focused on only thinking about things I told her to.

So knowing about her aversion to feet, I pushed her more. I told her to take my sock off. She did. Then I told her to kiss it, sure she wouldn’t. But she started kissing. No eye contact, no hesitation, no words. She just followed my commands.

I’d never thought about my sister in a sexual sort of way, but seeing the control I had at this point had me turned on. I told her to stop and grabbed her by the chin. I lifted her head to look me in the eyes and asked how she really felt about kissing my foot.

“How do you want me to feel?”

Damn… “I want you to like it.”

“I liked it.”

I know this is starting to sound like some made up fiction. I wouldn’t believe me either. But I had to write this out somewhere because I can still hardly comprehend it.

Anyway… I told her to follow me upstairs. On her knees. She crawled slowly behind me as I went into her bedroom, and waited as I tooted through her wardrobe.

I pulled out a lace bra and panties, and some hold up stockings. I told her to put them on. At this point I was still trying to break her, find the point at which she’d say no and snap out of it.

But she started to undress. In front of me, her own brother, not timidly nor erotically. Just matter of fact. Like this is the thing she has to do. She stripped completely naked and then slipped into the lingerie I had lying on the bed. Once she was done she just stood there, docile and sexy.

She honestly seemed so content I felt like I could’ve left and come back tomorrow and she’d still be standing in that exact spot.

My heart was pounding like crazy. I sat down on the bed and told her to sit next to me, which of course she did.

Then I reminded her that she didn’t have to do any of this. I was only pushing her, testing her, messing around (though a part of me was very much turned on). She could get up and leave if she wanted to.

“I only want what you want”

Goddamn. “Ok, then right now… you want to suck my cock”

I leant back, knowing that if my sister was really messing with me she’d take this as a joke, get up and admit she lost our game of wits. But instead she grabbed my waistband and pulled it down.

She started to move her head down and I shouted STOP!

“If you really do this, you can’t undo this”

She turned to me again. “I only do as I’m told”

“Ok. Then go ahead”

She smiled and took my head in her mouth. She gave one of the best blowjobs I’ve ever had. Took every inch and every drop.

After she was done I pushed her back on the bed and went down on her. Clearly we were both all in on this dynamic at this point, I might as well indulge. After I was done eating her out I lay with her. The regret was creeping in though not as much as I’d expected.

I told her she can have her phone back now. But she didn’t break.

“Do you want me to have my phone back?”

“Well… I guess so.”

I told her to go and get it and then come back. She went downstairs and back up again on all fours, even without me telling her. I guess the command stuck.

She got back in bed, phone in hand.

“Aren’t you gonna check it?”

“Only if you tell me to”

Clearly this dynamic wasn’t going to change. She’s still my obedient sister even now.
