My boyfriend and I broke up and I had sex with other guy

I broke up with my ex a few months ago. We were at a party, and I spotted a hot guy. We hit it off and went to the bedroom. We were fucking hard, completely lost in the moment, when the door opened. It was my ex. I froze, but my new partner kept going, not caring. My ex just stood there, watching as I took his cock deep inside me. I looked at him, trying to read his face. He was angry at first, but as I moaned loudly, his expression changed. He pulled out his cock and started stroking it, enjoying the show. The new guy came inside me, and we left, leaving my ex to finish himself off. I felt powerful, knowing I made both of them want me so bad. It was a hot, twisted moment
