Surprise Surprise

My girlfriend and I have messed around in the best and she likes to see me j/o and stuff. She asked me if I'd try role playing and I agreed. Well she tells me that she is going to give me the best orgasm that I've ever had and if I was willing to let her. Of course I did. She blindfolded me and told me to lay on my back. She started kissing me all over and starts jerking me off. Then she starts to finger my bum, which was weird for me but it felt ok. She started talking dirty and starting jerking and fingering faster and I shot a load of cum all over my chest. She scooped it up with her finger and put it in my mouth. It was so hot for some reason, as I had tasted my cum and tried anal masturbation for first time.
