Anecdote

This could be said to be my contribution to something that happened recently. Without giving away many details, I was living with my fiancé's parents and his sister, along with my girlfriend, a few days ago. I was planning to leave on a trip with my girlfriend but we had a fight the night before and went to bed angry, adding to it that we hadn't been intimate for a long time. The joke is that I woke up early to take a shower and when I headed to the bathroom, I saw his sister had washed some of her clothes and I, still upset and excited, grabbed one of her socks and put it in the bathroom, started masturbating with her sock while thinking about her because I've been wanting her for a long time. When I came, I ejaculated all over her sock, I have to say it felt very tasty, it was a sensation I'd never felt before. But after cum, I regretted what I had done and tried to clean up some of the mess I made haha and put it back where she had hung it. I want to clarify here that she didn't hide it or put it in a place where I wouldn't see it, I would like to think she put it in a place where she knows I'll see it but I have my doubts. I'd like to know what you all think, as these days even though I feel bad about what I did, when I see her I imagine her wearing that sock filled with my semen. Attached is a photo of the style of clothes she wears.
