I masturbated Infront of my sister again.

Not really, I decided to take a bath today and during it, I was bored, so I came up with this idea. It got me turned on so I touched myself from that point onward with a few breaks. Once I was done, I got dressed but intentionally left my cock out. I was so embarrassed to see if she would realize but so I knocked on her door and opened it but didn't show my full body. I was still masturbating and I asked her a few questions and said good night and left, I almost came from it but I held myself back so there wasn't any cum on her door. I don't know if she noticed or not because she gagged a little and said eww, BUT, she was also on the phone with her friends. Just throwing this out there as it happened today and I don't wanna forget about this post tomorrow morning.
