For my birthday this year, I told my gf there were a few things I wanted to do to her.
I wanted to tittyfuck her, which nobody had ever done with her before, and I after I wanted to finish on her face and in her mouth and have her swallow it. I had cum in her mouth just one other time before, and immediately she spit it back on my chest. Among other things I also wanted anal, which we’ve done plenty of times before, but this is about the tits and mouth part. Yes, I know, this is all a bit vanilla, but my gf is less adventurous than me and also assertive.
My dick is fairly small but her 34Es are plenty large enough and I’d done a brief dry run before so I knew it would work. (I’ve also tittyfucked girls with larger tits before)
So she tentatively agreed but pushed back a bit at me cumming in her mouth because she finds it kinda gross. Finally she said she would do her best to try it.
