For context, I 20m have been thinking a lot about my ex, because she was younger and shorter than me but dominated me and was stronger than me, and I thought yesterday that my sister, 18f (not sharing pics), could do the job. So I made a post about it, and a lot of people here gave me ideas, so I decided to go and see if she could dom.

So I went to her and spoke with her, and told her at one point that I bet I could beat her at armwrestling, and told her that if she beat me, I would do what she wants and she agreed. We did go and armwrestle, and she beat me soo easily. She made fun of me for being weaker than my little sister. She told me she wanted me to massage her back and shoulders, so she put on a crop top and sat in front of me.

When I started massaging her, I noticed her skin was smooth and her back was muscular, wich turns me on, and reminded me of my ex. I never thought this would happen, but I got hard over my sis! I became so nervous and started shaking, she noticed and asked me what was going on, and I told her that I was nervous because she would do anything she wants with me, and she told me that she easily could, and laughed because I was scared of her.(she dont know I got hard)

After a while, I finished massaging her and she said that I obeyed her and we should do that more often, and we talked a bit. But someone gave me the advice not too long ago to steal her phone and only give it if she could take it from me. So I did, I took her phone and ran away, but when she caught me, she pulled my arm towards her and made me fall to the ground, then she took back her phone. She got a bit angry and asked me why I did this, and I told her that it would be fun, and she told me to never do it again.

Later that night, I talked to her about how my EX would physically dominate me, and I loved it, and I told her that this is why I was nervous when massaging her. She told me that my story with my EX was hot.

I dont know how to feel now, this is very hot but I am not into incest and don't know if I can continue
