Open mouth kissing is a simple kiss,
With or without the slight use of the tongue.
It is normally a short, meaningful kiss.
This kiss is simply a step ahead of the average Peck
And a step below a full blown Makeout Session
NOTE : An open mouth kiss is exactly what it says
A kiss on the lips, with mouths slightly opened
To decrease awkward lip tightness for a more relaxing,
Enjoyable kiss.
