Sister-in-law caught me masturbating

So I was home alone I was feeling a little frisky. so I went to my bedroom and started pleasuring myself on my bed for maybe 15 minutes or so I was extremely into it I oblivious to my surroundings. The sister in law walked into the house. I did not notice at all. She goes into my bedroom and stand there and watches me play with myself. I truly had no idea how long she was there for and what exactly she seen. But as soon as I noticed, I stopped, we made eye contact and she smiled at me. (I did not cover up).

But she walked away with a smile on her face. I was not able to finish and got dressed. I walked out to confront her, but she was already in the shower. She did leave the door cracked open. I did a little peek, but wasn’t able to see much because it was too steamy. I was just able to see the silhouette. Once she was done taking her long shower, she walked by me as I was in the couch in her towel. We made an eye contact and she went into the guest bedroom.

We did not talk about it afterwards we just went about our business. But I jumped in the shower later in the day, and I didn’t notice that the showerhead was set to the pulsate setting, which never is. Makes sense why she was in the shower longer than usual. I’m sure she enjoyed herself. What are your thoughts?
