Just only...

As she tried her best to walk without falling over she could not help but count down the steps remaining before she knew she would lose it...

15 steps: Her toes were curling in her heels, it made it hard to balance on her feet. Her fingers were starting to stiffen. Her eyes wanted to roll to the back of her head.

10 steps: She had to slow her walk again. Her knees refused to bend from how stiff her legs were. Her vision was starting to blur.

5 steps: Her whole world revolved around the sensation between her legs. Her whole body began pulsing from pre-orgasmic twitches.

2 steps: She starts seeing white as her whole body relaxes and stiffens again in a massive twitch...

On the very last step before exploding, she reaches the bench of the bus stop and stops in her tracks. The halt in the movement stops the buildup, but now she is simply standing on the very brink, still having to fight off the impeding landslide, but it was starting to come back down slowly. She did not dare move a muscle. At that point a rather strong gust blew her dress up and massaged her drenched and exposed clit. That pushed her even closer, if it actually was possible, to what could have been the single biggest orgasm of her life.

She stood there, using all of her willpower to keep her body in check. It finally came back down and she was able to sit, releasing the strain on her tortured legs. It was only a couple of minutes after that she saw the bus turn the corner and start making it's way to her stop.

She was still on the edge. Would she be able to move again, and board the bus without succumbing?
