But seriously, I have not partaken in DATO. If you have it pushed near your face, would you not end up at least kissing it all over and cuddling it?
I cannot blame OP for wanting to devour it with his DATO. It is very tempting when you get your face between the two cheeks. However, the faint musky odour prevents me from proceeding any further.
Now we know that most MPAs and Escorts shower probably 10 or 15 minutes before the session. But that is enough of time to develop the musky smell again. If you want to eliminate the bacteria then use apple cider vinegar. Add some on to a cotton wool rub it between your cheeks or her cheeks until the bad odor is gone. Don’t worry about the vinegar smell it goes away after a time and it also does not burn. Natural apple cider vinegar kills bacteria and fungus it also has prebiotics which helps to promote good bacteria. Bragg Apple Cider Vinegar is one of the best to use.
