With more than a single partner, some long rests, and cat naps, about 9 hours.
Resulted in a sore EVERYTHING, carpet burns, sore jaw, two new bite marks, sticky all over, and was afraid to let anyone touch me for a week, 'cause I was so raw, front and back..
With just one partner, about 4 hours, but no naps.
