More efficient fucking

To your amazement, it isn't actually you who decides to move things along next. Instead, Diane takes some initiative at one point and whilst riding one cock in her pussy and sucking another, she starts fingering her own asshole. She collects a bit of spit dangling from her chin and uses it as lube to slide one, then two, then three fingers into her own asshole, deliberately trying to stretch it out for what's to come. She then uses the same fingers she just had in her asshole to beckon a man from the crowd to come over and start using her backdoor. This whole display only seems to reassert her role as nothing but a cocksleeve in your mind, removing any doubts you had about whether this new role for her in the office was going too far.

The man slowly lines himself up with her asshole, Diane paying him no attention as she continues bouncing on the cock in her pussy and messily sucking on another. However, her attention is drawn the moment he slips it into her backdoor, double stuffing the buxom whore. Her eyes shoot open wide as her focus is drawn to the intrusion at her rear. However, it's only a momentary distraction for her before she returns to her bouncing and sucking.

The gangbang continues on in this position for some time, with the men using each of her holes rotating through, with some of them reaching a climax and depositing their seed deep in one of her holes and others simply taking a break to allow a coworker a turn with the depraved MILF.

The moment one man deposits their seed into Diane's asshole, another is quick to take their place. It's only occasionally that enough time lapses between anal fillings that some cum does leak out of her rear end. This is often helped along by Diane unwittingly spreading her cheeks to welcome the next visitor to her back door only to cause more of a leak than expected.
