Push her away quickly!

In a fit of panic, you push Alison away from your loins and urge her to stand up. She almost seems frustrated at this, but you quickly readjust your attire before the person enters, especially pulling up the panties now at your knees. Beside you, Alison zips her shorts and shrugs, going to wash her hands. You do so as well, wanting to look as nonchalant as possible.

Entering the bathroom is a woman possibly in her forties, likely just here with her family. She doesn't seem to expect anything, and proceeds into a nearby stall.

You however are in absolute agony. Not only have you been edged enough today, but now you were **** away from an amazing orgasm by someone's tongue. You can feel it shaking between your legs, burning for release. You can feel your forehead covered in sweat, and with a paper towel you wipe as much of the drool away from your mouth as you can manage. But the sensation is there... You want to cum so badly, even more than before.

Alison starts to leave, but you tug on her arm desperately.

"What?" she asks. "We're done here, right?" She turns heel and leaves the restroom. You gave up your chance!
