I (19F) would often visit and stay in my boyfriend’s home. His family is wealthy and the house was large enough for all of us and was comfortable for the most part.
However, as the time went on, and I stayed for longer, I started getting more and more comfortable. Less manners, more freedoms, etc. On numerous occasions, my boyfriend’s dad would use the bathroom as I was in the shower. It did not bother me, but one time he came in as I was making myself cum in the shower. He must have known because he immediately apologized and left the bathroom. I quickly finished my shower and went to get dressed.
About a week later, he knocked and I told him to come in. He said he did not want to intrude like last time. I was humiliated but in some ways turned on by being exposed to him.
