I got fucked by a big dick on my bday and my bf doesnt know

I got fucked by a big dick on my bday and my bf doesnt know. We had a girls night and went to a bar. A guy hit on me and after a while I flirted back. Started with just a kiss then went further . My friends knew what was going on and let me go with the guy. When I first saw it I was shocked. It felt so good going inside me. I could feel every bit going in . I came faster than I usually do and then kept going for manybrounds. Now I think about it all the time and cant help but compare him with my bf thats small.. I want that feeling again and have even thought about a cuckold lifestyle for our relationship
