In one night, I basically turned into a "milking machine" for my best friend's little brother

A bunch of us were hanging out at her country house, and she brought her younger brother along. There was a ton of alcohol, and I got pretty tipsy. Everyone was taking turns going to the sauna, so I was walking around in my swimsuit. It is pretty revealing and definitely sexy. He is 18.

Of course, the guys kept staring, but her younger brother was the one who really turned me on. He was not looking at me in some hungry, animalistic way. He looked shy and embarrassed, even though it was obvious he wanted me.

I spent the whole evening teasing him on purpose. I would stroke his leg, casually press my chest against his shoulder, things like that. Whenever he handed me something or brought me something, I would always kiss him on the cheek.

When everyone else went to the sauna, the two of us stayed behind to make salads. That was when I noticed he had a huge erection.

I have no idea what came over me, but I offered to help him out. A few moments later, I had my hand wrapped around his dick and was jerking him off. At the time, I felt like this cool, experienced older girl who was giving him an amazing memory he would never forget.

He did not last very long, but I took that as a compliment.

Later that same night, he asked me to do it three more times. Seriously, I have no idea where he found the energy. We would sneak off somewhere private, and I would jerk him off again.

But the next day, once I was sober, I realized that this had been a really, really bad idea and that I had seriously messed up.

My friend already gives me crap about being "too wild," and now I went and did this with her little brother.

I am terrified she is going to find out, because if she does, I feel like our friendship is over.
