>>21748517She's got 3 holes and 2 hands to work with. That's 5x men at once. Assuming it takes her 10 minutes to finish off each man on average, that would be 30 men an hour. At that rate it would take 33.3 hours straight of taking man meat to get through them all.
Even if you bump the rate of COOM to 5 minutes per man (she would have to be godly at handjobs or choose exclusively quickshot men), it would take a whole 16.67 hours to get through all of the men with NO BREAKS. She would need to subsist off of COOM for an entire day and probably wash down the cum with energy drinks to keep up the rate for the whole 2 shifts of whoring.
The only other option would be to bump up the rate by getting good at giving footjobs to make it so she can handle 7 men at once. At that rate, it'd take 11.904 hours, or rounding up to 12 hours, to finish. That's a full factory shift of sex.
