[MF] fling at work, kept secret. Her First BWC

I’ve worked with this girl for a couple years and have gotten pretty close with her. We make each other laugh and just have fun at work. I do have a girlfriend though. So the other day at work she kinda gave me this look as we were talking about doggy style because of something completely random. She said “I bet you stretch out your girlfriend in doggy”. She has no idea how big I am. I replied “yeah and she loves it haha”. The day got later and we were the last two to leave so I waited to walk her out to her car because it was getting dark. In the elevator down she stood in front of me and just backed her ass right up on to me instantly making me hard. (She’s a red head with a really nice ass) When she felt me get hard, she turned and told me she wanted me to cum in her. Fuck it, so we went to a hotel, and as soon as we got in the room she pulled my pants down and was literally speechless as her jaw hit the ground. She instantly told me how much she loved it and started sucking it like crazy. She told me she was really tight because her bf was really small, but that she wanted me to stretch her ass and pussy out. I agreed. I told her to get into doggy. Damn her ass was so nice it made me harder. I brought the tip right to her pussy and she moaned. The second just my head was in I felt her whole pussy gripping it and getting soaked. I instantly went balls deep and she screamed, her legs shook and she told my she was mine forever. I started to go hard but every time I went all the way in and out her pussy would force my cock out and she would squirt everywhere. She was begging for my cum. She wasn’t on birth control but I still filled her up. She said she’s never had better sex. She literally told me she was mine whenever I wanted her. Might convince them both to have a three some as they both worship my cock haha.
