A door opens, right next to her

She had the button just below her tits open and she turned slowly while pulling the fabric apart. She was dancing and loving the risky exhibitionism and was about to be on full display from head to toes, save for the bunched up skirt over her hips. She was turning it into a strip tease.

As she turned, the door she was next to opened. You both froze for a split second. You were turned on even more that you'd just been caught, and even more that your wife is full-frontal flashing a person.

Hell, maybe a couple.

Maybe a whole room of people.

The iron surged back into your cock and it was as hard now as it was when you were in the elevator and were pumping her full of cum. She grinned filthily and kept dancing, her turn stopped, but her hands moved the fabric out of the way to completely expose her tits to the room occupant as you watched from 10 feet away. Her dance became more primal, he thighs parting and you knew between her own flowing cum and the creampie you shot into her, she was soaked.
