Previously published as MMF Straight to Gay MMF Short Story by Wallace, Natasha (AUTHOR).
Blake has a secret that he's never told his wife, Lily. He's always wanted to watch her with another man. When it slips out, one day, she surprises him by agreeing to give him what he wants. In search of the right man, they both find a beautiful stranger on a dating app. When the three of them meet up, however, the dynamic is unexpected. Blake and the stranger have palpable chemistry, and Lily takes notice. Their night is about to take a wild turn into uncharted territory with Lily leading the way.
Single perspective. Reminds me of a bottle rocket, quick burn, fire and done. No major flaws with the story. If you want quick and dirty, this does it. No real depth or errors.
