My Sister

Over the summer, my sister came home from a night of drinking, climbed in my bed naked and reached around and grabbed my dick. This ended with her almost begging me to let her jerk me off while I played with her pussy. We both came and fell to sleep.

This happened a few weeks later.

Last night, he first night home from college, she got drunk and the same thing happened.

I am not really sure what to make of this. She is a great sister and we have a good relationship, but this is on the edge of wrong.
