I Cheated On My Bf With A Stranger

I'm using a new account to post this because I he knows my username.

He is a very shy guy and not very muscular. A bit on the skinny side. I agreed to date him because I'd known him for a long time (our families are friends). I hadn't had sex in a long time and needed it. So I decided to do it with him. During the weekend, we went out. The whole time, I kept dropping hints by touching him and kissing him often. But he just smiled. I told him I was ready for it but he kept talking about something else. We went back to his place and I kissed him aggressively. He responded to it but then he got a call from someone and left me there. It was so frustrating.

A few days later, I was sitting at a park, calming myself by looking at the sceneries. Some guy sitting nearby said hi to me. He looked like the jerk type and had a smug smile. But since I was bored, I accepted his company and actually he was quite funny. He invited me to his place for some drinks and since I was having fun, I agreed. We drank and talked a bit. After a while, we were on the bed with him on top, pounding into me. After feeling horny the whole week, it felt so good. I was so wet and sensitive down there. He fucked me relentlessly. When I orgasmed, I remembered my boyfriend. He seemed so pathetic compared to the stranger on top of me. I gave him all the opportunity while being so sexually frustrated. But it was all relieved by this guy who I had just met.

My body wanted to let him come inside me, but I managed to force myself to push him off and let him shoot on my face. It was good sex but soon I realized what I had done and left in a hurry. I kind of feel bad for cheating. Should I tell him?
