The office was well lit and nice and warm and cosy and five big dick guys were all naked and standing in a circle around a cute woman who was crouching on a swivel chair in a position so that her bum hole was available for fucking.
Some of those uncut dicks were eye wateringly big and their bell ends were huge.
So the idea was that all the guys together placed a hand on her shoulder and pushed to get her spinning gently and wherever the chair stopped the erect penis nearest to her bum hole could fuck it.
So off they went, the first guy slowly entered her and she gasped as the big dick ended up deep inside her rectum and he could then fuck her for 30 seconds. We chose 30 seconds fuck time as we didn't want any of the cocks to cum too soon or the girls ass to get tired quickly.
So the guy who just fucked her could spin the chair now and see where it stopped next then that guy fucked her ass hole. This kept going on until a dick ended up cumming in her rectum then that guy was out. Some dicks fucked her ass more than others.
The last dick to cum in her ass had to have her squat above his face and fart all the cum out onto his face which was what all the guys wanted to happen to them so they all wanted to be the last to cum
