Without hesitation, when I see a TS provider I always got for DATO. I love it on women but even more on a TS. I start at the cock, work down to the balls and then there it is - so  I do it and sometime I go deep.

Guys - Is this safe and sane? DO you do it to?

For some reason, the front end tends to actually be cleaner than the human mouth.  So I will dive right in.  The back door, otoh, is the complete opposite.  There are all kinds of potentially nasty bacteria lurking back there.  So, even if it's just been washed, I won't go there.

For sure I do it every time, It is one of, if not my favorite things to do with TS women and usually my finisher if I haven't cum already. Have them sit on my face and jerk me off.
