I was at a girls house I know, she texted me and wanted sex. We skipped the oral part and she got on me to ride my dick. Her pussy felt extra wet this time but I just let her ride me. She got off of me so we could go to her bedroom and I noticed my dick was really wet and smelled like cum. I asked and she said she just got fucked a few hours ago. I got grossed out, washed my dick of in the sink and left. Is that odd?
