I'm 19 years old and my little sister is 11. I have anorexia and am 6'1, 115lbs. She's 5'0, 75lbs. Wasn't sure if I'm allowed to post a pic of us, so I just left it.
Anyway, my sister likes to have play fights with me and it's usually in good fun. The last play fight however turned vicious. She wrapped her thighs around my waist and squeezed hard. I submitted but she said she wouldn't let go until I said that "I was her b*tch". So I just say it, but she wants me to repeat another thing. She now wants me to say that "the only girl I can get is an ugly retard" referring to my autistic girlfriend. I reluctantly say this but she still won't let go.
Eventually I can't breathe, get a panic attack and then wet myself. I've only ever had 2 panic attacks before (exams) and have never urinated. I've never been so embarrassed in my life, I can't even look her in the eye anymore. I get panicky around her, how do I control this? Also, does this make her stronger than me? I don't believe she can be at such a young age. I just want to be normal.
