Last week I went to serve a bbc, I showed up and there were 2 of them there that took turns on me front and back repeatedly for 3 hours. It was ******* and exhilarating. It was like an x movie - what some of these people talk about as fantasy.
I was sore for a week but totally worth it. If you fantasize about this regardless of gender - do everything you can to be ready for it!!!
