I fuck my best friend Rioc's stepsister when I discover her in the shower

Rioc and Antonella come to visit my house, we are very good friends and I have a good time with them, today Antonella asked me if I let her shower and I had no problem, when I went to see how she was doing, I realized that she left the shower door open so that I could see her, She is a very attractive woman, I love her huge tits, it's all vagina she has, those labia that you look like sucking cock and delicious that they know how to fuck.
