I have to talk about this on a personal level,
because I don't offer DFK in my sessions.. but..
I love & am in love with being french kissed after some hearty oral.. after all the work I've done to make you cum.. that kiss is like bliss. I feel like only a mature man who knows himself sexually, though & through, would be willing to do such a thing.
Anyone who's squeamish about bodily fluids, during sex.. I can't do it.
