A friend of my brother was visting him a couple of weeks ago. I called my brother because there were some works in my building and I would have no water until the following day, so I could not take a shower. My brother told me that I could go to his house and have a shower after work, so I did. However, I did not know that his friend was there. When she opened the door, she told me that my brother was in the gym at that moment and he would be back later. I just told her that I would have a shower and leave. She said it was ok but smiled and asked whether she could take my suit off and help me have a shower. I thought she was kidding, since she is younger than me and I think she is having sex with my brother. Besides, I do not like her. When I was about to got to the bathroom, she insisted and took her t-shirt and bra off. Then she came to me and kissed me and we finally had sex before I entered the shower. She had condoms, so I assume that she had them to use them with my brother. She also told me that she wanted to swallow my cum, so I took my condom off before cumming in her mouth.
I finally had a shower and she went to the living room. She has been texting me for some days now but I do not want to have sex with her again.
She saw something like this.
