A silent introduction

The fun continues on like this for some time, with Diane likely unaware that there's even another woman in the room given that the only interaction she's had with either of her daughter's thus far is having her pussy eaten by Tracy, which for all she knows could easily have been one of the men from the office.

This all changes however during a regular position change where Diane ends up getting fucked on her back. Meanwhile, you position Tracy to sit on her face, resulting in a pussy being stuffed directly into Diane's mouth. She immediately makes a surprised sound, of course being confused as to where this pussy has magically appeared from. She does, however, start licking it without protest and just as much zeal as she was previously sucking the men's cocks.

You were concerned that this would be the point at which Diane would catch onto exactly what was going on, resulting in an early reveal of your big surprise for her. Considering the suspicious lengths you went to in order to avoid having her or her daughters' recognising each other by obscuring their vision and banning speech. However, it appears the MILF she has more tits than brains as she obediently laps at her daughter's pussy. Perhaps her mind is simply fried right now thanks to all the non-stop dick she's been receiving for the past hour.

Things once again quickly escalate to the rougher side as Tracy is soon bent over to be fucked in the ass and throat whilst her mother continues to dine on her pussy.

The group cycles through many more positions like this, with the girls remaining blindfolded and none the wiser of the nature of this particular orgy.
