Anna wanted to take pictures for my blog

Anna wasn't good at keeping secrets, and she wanted to remind it to me. I couldn't log into my blog, but I could see she was posting articles saying how bad I wanted to be fucked like a slut, to drink cum, to serve men. As expected, she also wanted to put on pictures once in a while, so she had to make me take some.

"Hey sissy! I need you to do something for me."

She was enjoying the power she had on me. It was a friday night, and she knew that after a week of school I needed to blow off some steam. When she entered my room I was watching porn, still wearing jeans, on top on my girl's panties. Anna was wearing a dark blue dress, like she wore to go out partying. She looked incredibly hot. Just to tease me ?

"I decided to allow you to post a few pics on your blog. So if you really want it, we can to take pictures of you being slutty. OK ?"

That wasn't a question, and it was not about what I wanted. It was about what she wanted. And I could not refuse. In part because it turned me on, and also because of what she said first.

"Today I almost copy pasted your blog adress to a friend of mine, you know ? Good thing I realized before hitting send. Can you imagine how people would react ? Haha... Anyway, we need to make you up, dress you up, and go onto the shooting location. Yes, I have a very good place in mind for those pictures."

I was afraid and horny at the same time. What was happening to me ? I wanted my sister so bad, and I enjoyed being threatened and **** like that to do things. She made me wear a short carmine dress of hers - perfect fit for my skinny body - with black thighs and heels. And with the make up and my hair done, I looked smoking hot, as she did. We went to the car unnoticed, and she took the wheel. I was still afraid, but at least a bit more confident considering my beauty at the moment. No one else would have known I was not a real girl. I had a boner in the car just thinking about guys enjoying to watch me dance.

But the fear overtook again when we parked next to a dance club. Anna got out of the car before I could say anything. I followed her to talk, but she was walking too fast for me in heels. I couldn't do anything but to follow her. She entered the club, and went straight to the crowd. The music was good, there was a lot of people dancing to the pounding drums, under the flashy lights oscillating between every possible color.

I eventually caught up with Anna, after finding a path through the crowd, not without feeling a hand sliding in my back and almost finding my butt while walking. My sister was just waiting for me in the middle of a group of people dancing like it was their last day on earth. She came closer and started dancing right in front of me, slowly first.

"You need to loosen up, sissy!" she said laughing. "Move with me!"

I just followed her lead and tried to sway my hips with hers. Soon her hands were around my shoulders, then brushing my hair, holding my waist. We were very close, our bodies touching each other. People were watching. The music was so loud and overwhelming, and the lights shooting from everywhere, and my sister's hands on me...

Behind, someone was dancing right against me for a few minutes. I only realized it at the moment Anna walked away from me smiling. I just kept on dancing like crazy, rubbing my ass on whoever was behind me. I could feel a boner between my cheeks. Some guy was hitting on me, probably thinking about how bad he wanted to fuck me. It didn't take long before another man got in front of me to rub his body against mine.

I didn't notice at the moment that my sister was taking pictures of us. But it wasn't the only reason we were at that club.
